Less emissions Merkel urges aviation to innovate

Status: 06/18/2021 8:35 p.m.

“As soon as possible”: Chancellor Merkel called for speed in innovations at the National Aviation Conference. Air traffic must quickly become lower in emissions. The industry is hoping for the summer business. The aviation industry and politics want to promote “green” flying in Germany with state funding. After the pandemic, all economic policy measures would have to be aligned with climate targets, said Chancellor Angela Merkel (CDU) at the National Aviation Conference in Berlin. “As for other industries, climate neutrality is a very ambitious goal for aviation,” said Merkel. To achieve this, there must be innovations, for example in drive systems and infrastructure – “and not at some point, but as quickly as possible”. Because the product cycles in aviation are very long.

Emission-free flying

In addition to the restart of the industry, which was badly shaken by the corona crisis, the focus of the industry summit at the capital airport BER was above all the path of aviation to emission-free flying. The airlines are focusing on the development of sustainable fuels as well as new, more economical aircraft and even electric aircraft. Representatives of the industry associations BDL, BDLI as well as the industry giants Airbus and Lufthansa repeated that this was a joint task of business and politics – and that is why public funds were necessary to kick-start innovations. The federal government is already investing billions in funding into the development of emission-free kerosene and clean aircraft technology. “At the moment, prices and quantities leave a lot to be desired,” said Merkel, referring to lower-emission fuels. Here you have to come to competitive terms. With extensive funding, alternative fuels based on electricity could also be ramped up on the market. Lufthansa boss Carsten Spohr said that synthetic alternatives to kerosene are around five times more expensive than fossil fuel today, and that PtL kerosene costs ten times as much. “No airline can afford that.”

No competitive disadvantage

With regard to the new climate regulations for European aviation expected by the EU in July, the Federal Government believes that stricter climate protection rules do not result in a competitive disadvantage compared to airlines abroad with lower standards. Merkel warned that there should be no distortions in the competitive struggle and no double burdens.

Aviation in Europe has been participating in CO2 emissions trading (ETS) since 2012, and the Corsia CO2 compensation system is to be introduced on a global level. “ETS plus Corsia does not work,” said Federal Transport Minister Andreas Scheuer (CSU). Corsia is the right instrument. The EU Commission considers this to be the weaker system.

Lufthansa wants to repay corona aid

Lufthansa was in dire straits due to the collapse of passenger flights in the Corona crisis and had to be supported by Germany and the countries of its subsidiary airlines with a financial framework of nine billion euros. Germany accounted for a total of 6.8 billion euros of the state rescue package for Lufthansa. The company has now announced that it intends to repay the state funds soon. “We were one of the first companies that was saved by the federal government. We also want to be one of the first companies to pay back the rescue funds – hopefully before the general election,” said CEO Spohr. The federal government, which in addition to loans and silent participation became Lufthansa’s largest shareholder with the rescue operation, wanted the state to withdraw “as soon as possible,” said Scheuer. With the help, the airline must get back on the road to success as quickly as possible. “And the state has to get out of there,” emphasized the minister.

Industry hopes for summer business

After the dry spell in the Corona crisis, aviation is relying on a recovery in summer business. According to the Federal Government’s Aviation Commissioner, new virus mutations could slow down the long-awaited restart. “At the moment there is great optimism and bookings are going through the roof,” said aerospace coordinator Thomas Jarzombek of the Reuters news agency. But everything depends on the infection situation. “Of course, there is now the delta variant as an uncertain component.” You can see in the UK that this delayed openings after the lockdown

Film industry “There’s never been more shooting going on”

Status: 06/18/2021 10:22 a.m.

The film industry is recovering from the forced Corona break. Due to the great pent-up demand, production is currently running at full speed. But the pandemic has consequences that will change the industry.

From Tina von Löhneysen, RBB

Backdrops on trolleys, trucks being unloaded, locked gates behind which secret stage sets are set up – in the Babelsberg studio there is a buzz. Christoph Fisser is a member of the board here and is in a good mood. In a polo shirt, he walks across the extensive grounds. “We are starting three major international productions these weeks, all of which are star-studded,” he says. You can hear the pride in his voice. “Not only here, it is shot everywhere like never before, because all films are being made up that were not made last year. They were all already financed.”

Make-up artists are hard to come by

The industry is booming. So much so that it is difficult to put crews together. Make-up artists and sound engineers are hard to come by because they are all already engaged in productions. Studio Babelsberg is a heavyweight in the industry. Founded more than a hundred years ago, films such as “The Blue Angel” or later “The Bourne Ultimatum” and “Grand Budapest Hotel” were shot here. It is considered the oldest film studio of its kind in the world. During Corona you only had to close for 16 weeks, two large-scale productions then continued filming in Potsdam. Although this was associated with a large logistical and financial effort – 60,000 tests were carried out for it, and now more meticulous testing is being carried out – but it has just continued.

The industry stood still

The industry as a whole was different. There was a standstill. It was hardly shot. The uncertainty was too great, the conditions too strict. Now there is far-reaching relaxation, the general sigh of relief and a lot of catching up to do, says Sebastian Lambeck from the producer alliance for film and television. But in perspective one will be able to observe a shift in production activity.

“Financing movies has become even more difficult due to the pandemic,” says Lambeck. Whether you get a film in the cinemas when it is finished, how well it is going: All this has become even more unpredictable due to the pandemic. And, quite clearly: The trend that was already emerging has accelerated enormously as a result of Corona: “The streaming providers are the winners of this crisis.” Babelsberg board member Fisser also notices this. The demand has more than tripled, which is due to the great hunger of streaming services for content. For Fisser’s company, that doesn’t really matter. When he shoots, it always makes money. But it hurts him a little. “We love cinema, you really have to say that. Personally, I much prefer to produce cinema films than serial, but the market has changed dramatically.”

“Films galore”

Despite all the changes: the good old cinema still exists. In these weeks, the movie theaters in Germany will open again, regionally staggered. “There are plenty of good films,” says Christian Bräuer, chairman of the AG Kino – Gilde eV

“In the next four months, about as many films will be shown in theaters as would normally be spread over an entire year,” he reports. Constantin Film AG, which is both a film distributor and a production company, confirms this. Like all distributors, they have an unusually large number of films on stockpile. That means for the cinema-goers: There is a huge selection of films. This is one of the reasons why the cinema operators are looking at the openings with great confidence. The hope: After the crisis there will be a boom – not only in film production, but also in watching films.

In recent days, the traffic police team number 11, the City Police. Hanoi constantly deploys troops, especially at peak hours to separate traffic, guide, as well as handle cases of motorbike drivers entering Thang Long Boulevard. According to the reporter’s actual record, the above violation is very common in the early morning rush hours and late afternoon rush hours. Notably, when asked, violators all said they knew about the above ban. However, because of hurry, forgetting, fear of traffic jam…so “missed” to go in. “I came home from the inner city of Hanoi in Thach That, when I turned onto Thang Long Boulevard, the road for motorbikes was blocked, so I went into the car lane. I knew this was a forbidden road, but I was afraid of traffic so I went in the wrong lane. With full vehicle papers, I was fined 2.5 million VND and temporarily seized the vehicle”, said Ms. expressed regret. Similar to the case of Mr. H. (Thach That’s family) said, this is the first time he entered the forbidden road, the reason was also because the lane for motorbikes was blocked. “I was fined 2.5 million dong and impounded the car. In the next few days, I am thinking of borrowing a motorbike to go to work, I am very sorry for the violation, “said Mr. H. All violators will be recorded, and vehicles will be impounded. When motorbikes and rudimentary vehicles enter the lane for cars, there is still a lot of potential for accidents, because the speed of travel for cars is very large. In fact, there have been many serious traffic accidents that occurred when motorbikes went to the wrong part of the road on this boulevard. Talking to PV, Senior Lieutenant Dinh Ngoc Hai (Traffic Team No. 11, Traffic Police Division of Hanoi City) said that the unit has continuously launched propaganda, rectified and handled violations. In the process of handling, the majority of vehicle drivers obey the orders of the traffic police, but there are also people who do not obey, ready to turn the vehicle, speeding and recklessly overtaking to avoid the task force potentially dangerous traffic. It is known that the above violation will be administratively sanctioned from 2 to 3 million VND, stripped of driving license for 4 months and temporarily impounded the vehicle for 7 days. Therefore, to ensure the safety of road users, it is necessary to consciously obey the regulations.

The speed of light (more generally, the speed of propagation of electromagnetic radiation) in a vacuum, denoted c, is an important fundamental physical constant in many areas of physics. It has an exact value of 299,792,458 meters per second, because the meter length unit is redefined based on this constant and the standard second. According to special relativity, c is the maximum speed that all energy, matter, and information in the universe can reach. It is the speed at which every massless particle bound to physical fields (including electromagnetic radiation such as light photons) propagates in a vacuum. It is also the propagation speed of gravity (such as gravitational waves) predicted by current theories. Particles and waves travel with velocity c regardless of the motion of the source or of the observer’s inertial frame of reference. After Einstein founded relativity, it became known that the speed of light is indeed very fast, because this is the upper limit of the local speed in the universe, and no other speed can be exceeded. through it. Moreover, regardless of the medium in the frame of reference, the measured speed of light is exactly the same. Based on the principle of the constant speed of light in relativity and the highly accurate measurement of the speed of light, physicists have also determined the speed of light to be 299,792,458 meters/second without affecting the speed of light. affect the current physical quantity. In this way, people no longer have to worry about accurately measuring the speed of light, and can also solve the problem of errors in the equipment used to determine the clock. The speed of light propagating in a vacuum is independent of both the motion of the light source as well as of the observer’s inertial frame of reference. The constancy of the speed of light was postulated by Einstein in his 1905 paper on special relativity. Physicists can now only experimentally confirm the speed of light by methods above two Two-way speed of light is frame-independent, because the speed of light cannot be measured in one-way speed of light, ignoring some conventions of uniformity. synchronization between the clock at the source and the clock at the receiver. Whether it’s electron transition, nuclear fusion, nuclear fission, or the annihilation of yin and yang matter, these processes produce light. Once light is created, their speed will immediately reach the speed of light, and they will always travel at this speed. If light were not absorbed by matter, they would not be dissipated in the universe, and the speed would always remain at the speed of light. For example, the first photons created in the universe 13.8 billion years ago are still present today, and they travel through the universe at the speed of light. So, how did light reach the speed of light? How does light maintain the speed of light? What is the driving force that drives the light forward? If it is explained from the point of view of the particle nature of light, then light is composed of photons with no rest mass. According to special relativity, since the static mass of photons is zero, their speed can only be the speed of light. According to the Higgs mechanism of the Standard Model of Particle Physics, when photons without static mass pass through the Higgs field throughout the universe, the photons will not be coupled, so they will not gain static mass, and their speed will not decrease. Once the photons are generated, their speed will directly reach the speed of light, and there is no acceleration from zero to the speed of light. Propagation of photons does not require energy to propagate, if they were not absorbed by matter or a black hole, they would always travel aimlessly through a vacuum at the speed of light. On the other hand, if explained from the evaporation of light, the nature of light is electromagnetic wave. Maxwell’s equations of electromagnetism show that electricity and magnetic fields are essentially unified, that a changing electric field excites a magnetic field, and a changing magnetic field excites a repeated electric field, creating out electromagnetic waves. Since electromagnetic fields are formed at the speed of light, electromagnetic waves travel at the speed of light. The generation and existence of electromagnetic fields are independent of the medium, so light can travel at the speed of light in a vacuum. Although the spatial structure continues to expand, light propagating through space will appear redshift, but they will not completely disappear in the universe.

Corona vaccine Which slows down vaccine production

Status: 14.06.2021 8:11 a.m. Corona vaccine is still scarce in Germany. The production of the vaccine has been running at full speed for months. What makes it so difficult to manufacture quickly in large quantities? From David Zajonz, WDR In theory, anyone in Germany has been allowed to be vaccinated for a week if they want to. In practice, more precisely in the doctor’s office, many people who want to be vaccinated receive the same information over and over again: “We would like to vaccinate you, but unfortunately we do not have enough vaccine.” In vaccination centers in North Rhine-Westphalia, there are currently no initial vaccinations at all due to supply bottlenecks. Almost six months after the start of the corona vaccination campaign in Germany, vaccines are still in short supply. The frustration of many people who have not yet received a vaccination is correspondingly great.

Previous production “absolutely sensational”

Nevertheless, the speed of vaccine production is enormous, believes Rolf Hömke from the Association of Research-Based Drug Manufacturers (vfa). It normally takes several years to produce a new vaccine on a large scale: “Judging by all the experience of previous vaccine projects, it is absolutely sensational how quickly the additional production was built up,” says Hömke. To clarify, he cites two figures: Before Corona, according to the World Health Organization, a good five billion vaccine doses were produced worldwide every year – against tetanus, measles and many other diseases. On the other hand, more than two billion vaccine doses had been administered in the fight against Corona by early June. According to current company information, more than 700 million vaccine doses of BioNTech / Pfizer’s most frequently used vaccine in Germany alone have been produced and shipped worldwide – up to three billion by the end of the year.

There is a lack of personnel and materials

There are several reasons why vaccine production is not progressing any faster. The production is complex, says Udo Reichl, an expert in the production of vector vaccines at the University of Magdeburg. “Vector vaccines are produced in bioreactors,” he explains. “Building a new production facility with bioreactors can take one to two years.” Therefore, production cannot be ramped up at will. Manufacturers also struggle to find qualified personnel. In addition, there is a lack of materials that are needed for production, according to vfa spokesman Hömke. “For example, there is a lack of spare parts for the production systems, sterile plastic covers and special chemicals.” Lipids, i.e. fats that are needed for mRNA vaccines, are particularly popular, says Hömke. “A large manufacturer of lipids for vaccines told us that at the beginning of 2020 they expected a few kilos of these lipids to be in demand. Now they can sell a few tons of them.”

Pharmaceutical companies work together

In order to be able to produce faster, the pharmaceutical companies enter into an unusually large number of partnerships. A prominent example is the collaboration between the small Mainz research company BioNTech and the US pharmaceutical giant Pfizer. The French manufacturer Sanofi, on the other hand, whose own vaccine project has stalled, plans to soon produce BioNTech / Pfizer’s vaccine in its Frankfurt plant. Another example: BioNTech has taken over its plant in Marburg from the Swiss pharmaceutical manufacturer Novartis – including its employees. It takes a long time to build new systems, explains vaccine expert Reichl. Conversely, converting existing production facilities is much easier.

March 31, 2021

Worry about poorer countries

The joint efforts of the pharmaceutical companies mean that the vaccine shortage in this country should soon be over: “In Europe we will see a gradual relaxation in the supply of vaccines over the summer,” believes Reichl. However, he worries about the supply of poorer countries. “A large part of the world population still has hardly any access to vaccines. If we need further vaccines in Europe to vaccinate against new mutations, these in turn will not be available for other countries.” So it could happen that Europeans and North Americans will be vaccinated three or four times while people in other parts of the world are still waiting for their first shot. It is therefore all the more important, according to Reichl, to set up further vaccine productions in poorer countries.

interview 04/26/2021

According to the Tianyancha APP, Beijing Huaguan Commercial Technology Development Co., Ltd. is a commercial enterprise with chain shopping malls and supermarket chains as its main business. Its main body is Beijing Huaguan Commercial. Beijing Huaguan Commercial Technology has invested in Zhuozhou City. 6 companies including Huaguan Supermarket Co., Ltd. and Beijing Yanxin Huaguan Trading Co., Ltd.

The entry of JD.com also means that the digitization process of Huaguan will be accelerated in an all-round way. It is worth noting that at the 2021 China International Retail Innovation Conference on May 24 this year, Feng Yi also stated that JD.com will in-depth cooperation with Arima to build an omni-channel retail benchmark, and launch digital synergy in the supply chain, omni-channel business upgrades, In-depth cooperation in member digital management has jointly promoted the omni-channel retail reform of Arima.

In fact, Huaguan and JD.com had cooperated a few years ago. As early as 2014, Beijing Huaguan Commercial and JD.com signed an O2O strategic cooperation agreement. In the future, they will be stationed on JD.com’s platform to sell products and be responsible for distribution. Although the cooperation between the two parties did not create much spark, Huaguan has never given up the idea of ​​building an omni-channel. It is understood that in 2017, Huaguan Supermarket and WeChat Pay launched a self-service payment applet, and replaced waiting in line with one-click payment on mobile phones, realizing an automated supermarket shopping experience.

On January 24 this year, Zhang Bing, a representative of the Beijing Municipal People’s Congress and chairman of Beijing Huaguan Commercial Technology Development Co., Ltd., revealed in an interview with a reporter from Beijing Commercial Daily at the Fangshan District Group Meeting of the Fourth Meeting of the 15th Municipal People’s Congress that Huaguan Supermarket in 2021 It is expected that 10 new stores will be opened in Beijing. At the same time, Huaguan Supermarket will continue its digital transformation.

Zhang Bing told a reporter from Beijing Business Daily that some roads were closed due to the fluctuation of the epidemic, which affected the stability of the supply of goods. This requires companies to be fully prepared in peacetime to deal with emergencies. This poses a challenge to the responsiveness of the company’s supply chain, which means that we need to be predictive, and the basis of the pre-judgment is the digital operation of the production area, inventory, scheduling, and sales. Supermarket retail must change from extensive to refined Transformation of operations.

It can be seen that the supermarket retail industry and the Internet have moved from antagonism to integration, the former has gone from lively to deserted, the latter has gone from small to unshakable, and now the combination of the two, the supermarket market has also entered a new Internet era and new Retail stage. As Ali started to take a stake in RT-Mart in 2017, Ali’s digital transformation is also getting better. This has also allowed more and more companies to follow suit. Especially during the epidemic, supermarket online orders surged, and online platforms became the second growth curve driving traditional supermarket sales. This also allows physical supermarket companies to see the prospect of digitalization and accelerate the pace of digital transformation.

Wen Zhihong, partner of Hejun Consulting and head of chain management, said in an interview with a reporter from Beijing Business Daily that the current digital wave in the supermarket industry has arrived, and the business model of the supermarket industry in the future will no longer just stay in the original offline. Physical stores are moving towards omni-channelization.

“Comprehensive integration actually means the reconstruction of the traditional retail industry, including commodity management, customer service, store management, and store planning. Great changes have taken place. It will be very difficult to develop on your own capabilities alone. . The development of an enterprise will have different leading forces at different stages.” Wen Zhihong analyzed.

Donnie Yen (right) and Nicholas Tse in the movie Fury. Movie content Wrath of Fire revolves around the tense confrontation between crime boss Khau Cuong Ngao (played by Ta Dinh Phong) and the leader of the crime team Truong Sung Bang (played by Donnie Yen). Initially, the character Khau Cuong Ao was a good friend of Inspector Truong Chong Bang. But for personal gain, Khau Cuong Ngao colluded with criminals and became a murderer. Recently, when the film was about to be released, the Hong Kong martial arts star (China) recalled the films that made a name, including Ip Man . The actor remembers Mike Tyson’s heavy punch when filming Ip Man 3 (2015). Recalling the scene above, Donnie Yen said he thought he would have died if he hadn’t dodged the blow in time. “Just a little carelessness, punches can be fatal,” Donnie Yen told SCMP. Donnie Yen and Mike Tyson. “When I first met Mike Tyson, I was very emotional. I don’t think I’ll be acting with an idol. I was really worried at first. I’m afraid he can’t control the force of the punches because Mike is actually not a professional actor. I was very cautious,” said Donnie Yen. When filming Ip Man 3 , Donnie Yen always considers this a life-and-death boxing match. He recalled his fight with Mike Tyson in the action movie. For a moment, Mike’s punch grazed Donnie Yen’s head, even coming close to touching the Hong Kong actor’s hair, before the punch hit the sandbag behind. “I had to immediately lower my head to avoid an accident. He used a lot of force, even all of his energy, to throw the punch. As Mike approached, I felt like a big truck was coming towards me. Eight years later, I still remember that dangerous moment vividly,” film star Ip Man told SCMP. In the movie Ip Man 3 , Donnie Yen as Master Ip Man, this time used his martial arts skills to protect good against evil. That’s why Ip Man became an enemy of Frank – a gang boss specializing in looting and oppressing civilians in 1950s Hong Kong played by Mike Tyson. The fight scene between Donnie Yen and Mike Tyson in the movie Ip Man 3. The scene of Ip Man vs Frank impressed the audience and was considered the most “expensive” scene in Ip Man 3 when the audience had the opportunity to admire the high-low competition between modern boxing and traditional Wing Chun martial arts. system of China. Talking about Mike Tyson, Donnie Yen shared: “He is too famous in the world boxing world. People may not know who Donnie Yen is, but everyone knows Mike Tyson. That’s why I always stay focused when duel with him. Just a little loophole, I will pay the price. Mike Tyson’s attack speed is very fast, I also dodge quickly but still feel like I have just narrowly escaped.” Meanwhile, Mike Tyson also used many words of praise for his colleague. “This is my first time acting in a martial arts movie. On the set, I completely followed Donnie Yen’s guidance,” Mike said. After an encounter with “the scariest man on the planet”, Donnie Yen said that Wrath of Fire is the action film that makes him most satisfied in his decades of filming. Quoc Tiep (th)

Illustration. For ants and small animals, the resistance of the air helps them a lot and makes their falling velocity very slow, sometimes their acceleration is negative (due to the wind blowing up). Thus, ants are almost unharmed when falling from the roofs of high-rise buildings. All objects falling through the air have terminal velocities that depend on their size, shape, and mass. The terminal velocity of an ant (6.4 km/h, according to the physics department of the University of Illinois) would be vastly different from the terminal velocity of a human (about 200 km/h). “For rats and any small animal, there’s really no danger. You can drop a rat into a minehole nearly 1,000 meters deep and when it hits the bottom, it’ll be slightly stunned and run away. , provided that the ground is fairly soft.The air resistance acting on a moving object is proportional to its surface.If the length, width and height of an animal are divided by 10, respectively, the mass is its mass is reduced by 1000 times while the surface area is reduced by only 100. Therefore, the air resistance for small animals is usually 10 times higher than the driving force. Force isn’t usually a problem for an insect, it can be free-falling without danger, with the ability to grip.” Michael Kaspari is an ecologist at the University of Oklahoma (USA) who has studied the aerial activities of wingless ants. Research shows that when ants are facing a predator, they will jump right into the air from tall tree branches and use their legs to control the direction of flight to reach the tree trunk. The longer hind legs will help the ants glide through the air, helping them avoid falling into places they consider dangerous. With this ability, it is possible that the ant has found a way to cling somewhere before it falls to the ground, but whether or not the ant does, the ant will not die if it hits the ground. The most ancient creature that still exists to this day It is said that the earth currently has 10 million billion ants, despite the fact that they are killed a lot every day. According to the biological kingdom, it is estimated that ants account for 15-20% of the total number of animals living on land. Ants are animals belonging to the order of membranes, the class of insects. Scientist Corrie Moreau and French colleagues published a study showing that ants appeared between 140 and 170 million years ago. That means they are the most ancient creatures that still exist to this day, despite the violent fluctuations of the earth. Since then, it has been found that ants have a very high ability to survive in all weather conditions. Such survivability is endowed by nature, for they show no sign of changing accordingly. Which means it’s very likely that an ant 170 million years ago and an ant today would be no different. It is thought that the earth exists about 20,000 different species, with 4,500 families. They are present everywhere on earth. Even the extremely cold places are the poles of the earth, or the hot center of the equator. Ants come in many varieties, but the color is usually just red or black. Especially, there are new species mixed with white color. Ants are gregarious species, with a rather distinct social organization. Each ant nest has an average of about 100,000 children in a colony with a single mother (Christian ants can live up to 30 years). Here, there is something like the organization of a swarm life of bees. The vast majority of ants in the colony are worker ants (who only live for 1-2 years) – likened to the hardest workers on earth. The job of worker ants is to take care of the queen, incubate eggs, transfer eggs, raise baby ants, build burrows, find food, guard … Not many people know that all worker ants are female, but their reproductive organs are not fully developed, so they can never become a god, but are forever just “cool” feet from birth. until death. Ants are considered to be the strongest species because they can carry food 10 times heavier than themselves. But to transport that heavy amount of food, they must use collective strength in coordination. Together they carry the food they earn very easily, when thousands of them work together. Ants are everywhere, everyone can see them or be bitten by them, but few people know that they also have positive effects. The Masai people of eastern Africa have a habit of using ants as a tool to heal wounds. When a member of the tribe is injured, they will catch a few large ants in the swarm of “army ants” so that they bite on both sides of the wound, then remove the ant body, leaving only the ant head on the wound. Since then the wound does not bleed and heals quickly. And interesting things about ants Ants are animals with a fairly hygienic life. Specifically, the handling of dead animals. When one ant dies, the other ants in the colony will together carry the dead ant out of the nest, with the sole purpose of keeping it clean and avoiding infection or disease spread. The workers will take care of the carrying, under the command of an ant that is supposed to be in charge of the burial of the colony. It is also surprising to learn that ants are insects with very advanced organizational systems. Along with the Lord ant, worker ant, and burial commander ant, there are also ‘teacher ants’ Born, in order to have the necessary skills, they undergo a learning process under the guidance of “teachers”. The “teacher” ants in the nest will teach the younger ants to do the necessary work. In case the “student” learns slowly and “fails” in the test, they will be transferred to another job that requires less skill. Not only know how to find termites, but ants also know how to “livestock” to create food reserves. They feed on insects such as aphids and caterpillars to obtain the sweet substance secreted by these insects. When it’s time to harvest the sweetener from the insect swarm, the ants “milk” using their antennae. It is very interesting to know that ants bring with them the insects they nourished when they move to a new area. It’s no different than people taking livestock with them to more verdant places. People have talked about the extraordinary in the world of ants. They have no ears but perceive sound from ground vibrations, through sensitive sensors on the pins. They have the ability to exist to the point of fantasy despite the harshness of weather and climate. Therefore, ants are also one of the first creatures on earth to be sent into space by humans in an experiment to conquer the sky. Ants have poor eyesight, but they often use the earth’s magnetic field to navigate. They are considered the most intelligent insects when in the small head of ants there are more than 250,000 brain cells. As industrious animals, ants are also said to be “excellent athletes”. If an ant were about the same size as a human, they could run at an average speed of 55 km/h without ever getting tired. They are also able to lift an object 50 times its own weight with extraordinary strength.

Born… as a historical necessity To learn more about one of the oldest and largest railway systems in the world, RFI Interviewed engineer Ta Quang Anh, working at the French National Railway Corporation (SNCF) about the birth of the French railway network. The engineer said that the French railway industry was “conceived” in the first three decades of the nineteenth century. Appearing more slowly in England, where the first steam engine was mounted on railcarts in trade fairs from about the mid-1810s, the birth of the French railway network was also in the similar scene, as a historical necessity. That necessary background is the final stage of the First Industrial Revolution in Europe, the period of the meeting between supply and demand. Regarding demand, in the economic field, it is the need to transport finished products in large quantities, especially in the mining industry and later in chemicals, textiles, and agriculture. In the political field, it is the need to plan territory, unify transportation and administration in a large country with many diverse geographical and cultural characteristics. The achievements of metallurgical technology have enabled the production of quality steels for train wheels and tracks, especially with production capacity for thousands of kilometers of track. In terms of supply, it’s the ability to respond to technology. This is also the intersection of two technological factors that have both developed to the necessary maturity at that time. On the one hand, the achievement of metallurgical technology has allowed the production of quality steels for train wheels and tracks, especially with production capacity for thousands of kilometers of track. On the other hand, in the mechanical and steam engine industry, the soul of the industrial revolution, despite overcoming barriers to liberate labor, is still an inspiring creative ground for optimization in terms of technology. performance and size. On the French side, in 1823, the first railway, 18 km long, connected a coal mine from the vicinity of Saint-Etienne down to a port of the Loire in Andrézieux. Although only using gravity to transport coal to the river port and using horse power to pull construction materials in the opposite direction, in terms of infrastructure, this is considered the first line of the French and European railway network. continent. Only 7 years later, another 58 km line connecting Saint-Etienne with Lyon was also put into operation. This was the first time in France, the steam locomotive improved by French engineer Marc Seguin was put into use instead of horses with a record speed of 12 km/h at that time. A year later, in 1831, the line also began carrying passengers. In 1823, the first railway, 18 km long, connected a coal mine from the vicinity of Saint-Etienne down to a port of the Loire in Andrézieux. In 1814, at the very beginning of the world’s railway history, when it first appeared in England, a strategic report was submitted to Emperor Napoleon by Chief Engineer Moisson-Desroches, highlighting the importance of it. of planning a railway network of seven lines radiating from Paris to all parts of the “hexagonal country”. By 1837, the strategic idea of ​​Moisson-Desroches was concretized in the planning of Alexis Legrand, then the General Architect of roads and mines of France. The drawing that later became known as the “Legrand Star” was the first planning map of the French railway industry. Also in 1837, the first dedicated passenger railway was put into operation, connecting Paris to the suburb of Saint-Germain-en-Laye. On paper and in the field, 1837 can thus be considered the “AD” year of the French railway history. Before World War I, nearly 60,000 km of Line 1 covered France, a sixfold increase in about 60 years. After about 15 years of relatively spontaneous development (since the railway law 1842 stipulates the model of railway socialization), by the end of 1858-early 1859, the railway agreement between the State and 6 railway companies was established. iron is an important legal corridor for network development. This agreement is meant to divide the development market share of private companies authorized by the State to develop the arterial railway system. In 1865, the law was expanded to allow local governments to be authorized to build and operate branch and cross lines for railway companies. The period of the second half of the nineteenth century and the early years of the twentieth century, with the development stimulus mechanisms of the central and local governments, was the period of breakthrough development of the French railway network, at least in terms of total length of routes in the whole system. By the time of World War I, nearly 60,000 km of Line 1 (now about 30,000 km) covered France, a sixfold increase in about 60 years. All provincial administrative sub-areas are connected to the railway network. Also during the early twentieth century, power options such as electric and diesel were also tested and developed for locomotives. The birth of the SNCF was the result of the nationalization of the railway industry in favor of the plan to electrify the entire railway network, a proactive step after the energy and economic crisis of the 1930s. In 1938, the National Railway Corporation (SNCF) was established. The entire 42,700 km of railway with debts and more than half a million railway employees are combined into one. The birth of the SNCF was the result of the nationalization of the railway industry in favor of the plan to electrify the entire railway network, a proactive step after the energy and economic crisis of the 1930s. This was considered the optimal political-economic choice at that time, in the context that the precursor private companies of SNCF faced a lot of financial difficulties after a period of overheating development in terms of terminal infrastructure. In the nineteenth century and especially after the years of World War I there was no source of income, which was followed by the Great Depression of 1929. Railway unions, representing more than half a million workers, became industrial unions are very vocal in society, contributing significantly to workers’ movements. A breakthrough in quality The operating speed at that time was 260km/h, in the same year, the design and test speed reached a world record at 380km/h. The birth of the TGV opens a new breakthrough development phase for the French railway industry. Unlike the breakthrough period in infrastructure in the second half of the 19th century, TGV has “miniatured” France and even Europe with only 3-4 hours of travel. During the period 1990-2010, many domestic TGV routes were inaugurated, notably the Eurostar route running through 50 km of the English Channel tunnel to the UK, the Thalys route going to Belgium and the Netherlands… In 1997, the State separated the infrastructure management part from the SNCF by establishing the National Railway Network (RFF). This is the first step of France when implementing commitments on competition in the field of rail transport in the European Union (EU). In 2015, RFF re-entered a member company of SNCF, after having spun off the mining part into another independent subsidiary in the group. In 1981, France put into operation the first high-speed train line TGV connecting Paris and Lyon. In 2007, France once again broke the world record for the test speed of the express train at 574.8 km/h. To date, this is still the world record for train technology running on rails. In 2020, the state monopoly on train operation officially ends. During the last 30 years of the twentieth century, the absolutely safe operation of 400 tons of steel on rails at 320 km/h has always been a technological icon in the ground passenger transport industry. TGV technology is exported and transferred to many countries, in Europe, to the US, Morocco and even Korea. For the French, TGV is a “national pride”. According to a poll of the French population, the TGV is considered one of the most important inventions of the 20th century, along with the computer, mobile phone and microwave oven. For the passenger railway industry, TGV was born as a lifeline in the context of the energy crisis of the 1970s, the aging of the traditional railway system from nearly 150 years made the railway no longer an option. number one choice for travel needs as highways thrive and air routes become increasingly accessible to price segments. In passenger transport, the decisive factor is not necessarily the speed of travel, but the sum of travel time, comfort, safety and, of course, price. TGV was born to most harmoniously meet these factors. TGV routes connect the centers of major cities (in France and later in Europe, both mainland and British islands) in the journey with moderate time, high safety, good service quality. The railway network in France is operated by the French National Railways Corporation (SNCF). For those doing railway engineering and technology, TGV’s 20 years of conception, 40 years of exploitation, perfection and development has been and will be an inspiration for technical innovation initiatives in many years. fields, from structural infrastructure, energy, signal information to rolling stock; from the construction and manufacturing industry to the maintenance industry. According to engineer Ta Quang Anh, the nearly 200-year history of formation and development is an advantage of French railways. In the world, besides the UK, there is no country as “rail age” as France. This is a great advantage in terms of experience. The coverage of the French railway network compared to the entire geographical territory is very high. Although France is not a country with a very high percentage of urban population, according to one statistic, about 89% of the French population live less than 10 km from a train station (in cities like Paris, this distance is much smaller). . This contributes significantly to the formation of habits and the need to use railways for transportation. About 89% of the French population lives less than 10 km from the station (in cities like Paris, this distance is much smaller). This contributes significantly to the formation of habits and the need to use railways for transportation. On the other hand, rail transport in France with over 80% electrification is a fundamentally environmentally friendly transport industry. With such a large coverage, in the medium and long term future, with the commitments of the French Government to reduce greenhouse gas emissions in the framework of global environmental agreements, railway transport (both cargo and passengers) will undoubtedly remain key government priorities. As more than 80% of the railway network is electrified, with France’s civil nuclear power capacity, the French railway industry has a huge advantage in terms of energy initiative over most railway countries. However, the French railway industry also faces some limitations. A prime example is the British railway industry, which has been in decline since the late twentieth century. In the case of the French railway industry, in terms of people, changing production habits is no longer suitable for the application of modern means and production methods, in many cases, encountering resistance from the government itself. old experiences. In terms of infrastructure, most of the French railway network was designed and built before the twentieth century. Adapting to climate change is a big challenge for network maintenance and repair. TGV is a legacy engineering innovation based on ballast rock infrastructure and wheel-rail contact. But if you want to increase the speed of operation to over 400 km/h, such infrastructure is likely no longer suitable, especially when put on the balance sheet with the cost of maintenance. Of course, train speed is not a prerequisite, but if France decides to race in this direction, it must accept going slower than other countries that have developed or transferred technology for maglev infrastructure. such as Germany, Japan, China.

People wait for their turn to get vaccinated against COVID-19 in Beijing. Photo: AP According to CNBC, within just 5 days of May, China injected 100 million doses of the COVID-19 vaccine to its people. Health officials hope to be able to vaccinate 80% of its 1.4 billion population by the end of 2021. As of June 2, China has injected a total of over 704 million doses of vaccine, of which half were administered in May. The total number of doses of COVID-19 vaccine that China has given to the population accounts for about one-third in one. ,9 billion doses of vaccine are distributed globally. The call to vaccinate is from all walks of life. Companies inject workers, schools urge students and teachers to immunize, local authorities urge people to vaccinate. According to Our World in Data, in 7 days, China is injecting an average of 19 million doses per day. With a population a quarter of China’s, the US only injected 3.4 million doses / day in April – when the vaccination campaign was operating at full speed. A medical worker administers a COVID-19 vaccine at a vaccination site in Shanghai, China. Photo: THX/VNA On May 30, Zhong Nanshan, the head of an expert group of the National Health Commission of China, said that 40% of the Chinese population has been vaccinated with at least one dose, and the government’s goal is to fully immunize all patients. this number at the end of June. In the capital Beijing, 87% of people have received at least one dose of the COVID-19 vaccine. Vaccination in Beijing is easy because there are hundreds of vaccination service points throughout the city. Vaccination buses are parked right in crowded areas such as city centers and commercial centers. However, vaccination in other areas is not as easy as in the capital. Ms. Zhou Hongxia, a resident of Lanzhou, Gansu province, said: “I started waiting in line for the injection at 9am and didn’t get the injection until 6pm. It’s tiring. When I returned, there were still people waiting.” Ms. Zhou’s husband couldn’t even schedule a vaccination. On May 31, government officials said they were working to ensure the supply of COVID-19 vaccine is distributed more evenly. Not only focusing on inoculating people in the country, China also injects its citizens abroad when donating vaccines to Thailand, part of which is used to vaccinate the Chinese before giving them to Thai people. Globally, China has injected more than 500,000 citizens abroad. Before the domestic vaccination campaign accelerated in recent weeks, many Chinese people were in no hurry to get vaccinated because China had almost no cases in the community thanks to tight border controls and mandatory isolation. Recently, China has appeared many small clusters of infection and is suppressing the cluster in Guangzhou. According to analysts, despite the uneven distribution of COVID-19 vaccines, Chinese manufacturers have hardly had problems with the scale of production. Both companies that produce most of the COVID-19 vaccines being used in China, Sinovac and Sinopharm, have drastically increased production, built new factories and converted existing factories to produce COVID-19 vaccines. . Vaccines of Sinovac Biotech (China) at a vaccination center in Bangkok, Thailand on May 12, 2021. Photo: THX/VNA Vaccines from Sinovac and one from Sinopharm have been approved for emergency use by the World Health Organization. “Where in the world can match China in terms of construction speed? How long does it take China to build field hospitals? Just a few days.” Sinovac said it has doubled production capacity to 2 billion doses/year, while Sinopharm said it can produce 3 billion doses/year. From the beginning of the year to the end of May, Sinovac produced 540 million doses of the COVID-19 vaccine. Government support is crucial for vaccine manufacturers at every stage. Sinopharm said that right from the start of the vaccine research, it had borrowed a laboratory at a government research center. Chinese vaccine companies largely do not depend on imported products in the production process, so the scenario of shortage of raw materials and ingredients like the Serum Institute in India should be avoided. As of June 4, China had 91,194 cases of COVID-19, of which 4,636 died.

A healthcare worker is vaccinated against COVID-19 at a hospital in Kolkata, India. Photo: AP In India, the number of infections on May 30 was 165,553 cases, the lowest level in the past 6 weeks. The number of deaths also tended to decrease, to 3,460 cases and the third day in a row below 4,000 cases.

The vaccination campaign is being accelerated by India, although vaccine supply remains a big challenge. As of May 30, India has injected more than 212 million doses of the vaccine, ranking third in the world after China and the US. About 12% of the population was vaccinated with at least one dose, of which 3.1% were fully vaccinated. Prime Minister Narenda Modi’s government said on May 30 that about 120 million doses of the vaccine will be included in the vaccination program in June, a significant increase from 79.8 million doses in May. , government advisers also said that India could reach a supply of 2 billion doses of vaccine between August and December this year, mainly from two domestic manufacturers, the Serum Institute of India (Serum Institute of India). SII) – responsible for producing vaccine samples of AstraZeneca and Bharat Biotech Company, the focal point of domestic production of Covaxin vaccine. In June, the government will provide 60.9 million doses of vaccine to the states to vaccinate health workers along with some other forces on the frontline against the epidemic, people over 45 years old. About 58.6 million doses will be ordered and distributed by state governments and private hospitals. Malaysia on May 30 recorded 6,999 new cases of COVID-19 and was the 5th consecutive day of outbreaks of infection. The government of this country plans to set up more large-scale vaccination centers, mobilize private medical staff to participate in vaccination campaigns in the context of Malaysia preparing to implement a nationwide shutdown. for a period of two weeks, from June 1-14. Medical staff take samples for COVID-19 testing for people in Selangor, Malaysia on May 23, 2021. Photo: THX/VNA Speaking at an online press conference on May 30, Malaysian Minister of Science, Technology and Innovation Khairy Jamaluddin said the government will establish five new large-scale vaccination centers in Kuala Lumpur and have Two more similar centers could be established in the northern state of Penang and the southern state of Johor. Each of such centers has the capacity to administer 40,000 doses of vaccination per day. The Government will also conduct training and training for doctors and nurses to perform vaccinations, stemming from the fact that some vaccines need different handling and storage methods and are different from conventional vaccines. Mr. Jamaluddin also said that the supply of vaccines will increase in the near future, so the government will mobilize manpower from hospitals and private medical centers to voluntarily participate in the vaccination campaign. According to Jamaluddin, Prime Minister Muhyiddin Yassin’s government is also expected to set up mobile vaccination centers at roads to vaccinate people. Currently, about 6% of Malaysia’s 32 million people have received at least one vaccination. In the Philippines, the head of the Philippine Government’s COVID-19 Task Force, Mr. Czar Carlito Galvez Jr, said on May 30 that more than 5 million doses of the vaccine have been administered to people, after nearly 3 months of implementation. vaccination campaign. People wear masks to prevent COVID-19 infection in Manila, Philippines. Photo: THX/VNA Most of these were administered to priority groups, including 1.4 million doses for healthcare workers, 1.368 million doses for the elderly and 1,150 million doses for people with underlying medical conditions. Vaccines introduced in the Philippines include Sinovac, AstraZeneca, Sputnik V and Pfizer. Galvez also said that in June, the Philippines is expected to receive an additional 10 million doses of vaccine, including the amount of vaccine through the Covax Initiative program, 2.3 million doses of Pfizer vaccine, 2 million doses of AstraZeneca vaccine and 1 million doses of vaccine. Sinovac vaccine. The first batch of 250,000 doses of Moderna is also expected to arrive on June 21. The administration of President Rodrigo Duterte has set a target of vaccinating about 70 million people or more than 50% of the population this year. However, this plan is facing major challenges. In addition to the limited supply of vaccines, the lack of confidence in Chinese vaccines is also a big barrier. It was Mr. Duterte who recently had to speak to reassure, urging people to avoid the mentality of choosing a vaccine, but to see that having a vaccine to inject is already a good thing.

Produced | Tiger Sniff Technology Group Author | See you Head Picture | Visual China The female car owner’s rights defense incident at the Shanghai Auto Show pushed Tesla to the forefront. Yesterday afternoon, Tesla emailed the female owner’s data about the car in the accident, and announced the data 1 minute before the accident. However, according to the latest news from Elephant News, the female car owner was still in detention and could not receive outside news. Her husband, Mr. Li, believed that Tesla’s public data violated personal privacy. Tesla explained this one minute before the accident: “When the driver stepped on the brake pedal for the last time, the data showed that the vehicle speed was 118.5 kilometers per hour. Within 2.7 seconds after the driver stepped on the brake pedal, the maximum brake master cylinder pressure was only 45.9 bar. After that, the driver increased the stepping on the brake pedal, the brake master cylinder pressure reached 92.7bar, and then the forward collision warning and automatic emergency braking function was activated (the maximum brake master cylinder pressure reached 140.7bar) and played After the ABS was applied, the system recorded the occurrence of the collision. After the driver stepped on the brake pedal, the vehicle speed continued to decrease. Before the collision, the vehicle speed was reduced to 48.5 kilometers per hour.” Although Tesla claims that vehicle data is encrypted and stored and cannot be directly read, modified, or deleted. When product disputes arise, Tesla will provide true and complete vehicle data in accordance with the law, but there are still voices questioning the authenticity of the data. A brake technology expert told Hu Xiu, “This kind of Excel table data is easy to be tampered with.” “The data is meaningless, it is impossible to determine whether the data has been tampered with, and more information about Bosch brake systems needs to be disclosed.” Zhang Xiang, a member of the new energy and intelligent networked automobile industry expert think tank of the Ministry of Industry and Information Technology, believes that in general, data should be uploaded in real time The data that is hosted by a third party or government agency and then released from the third party’s server is more credible. According to relevant experts interviewed by China Daily, there are three possible reasons for Tesla’s “brake failure”: One is the poor interaction between the car pedal and the iBooster brake-by-wire system, or the vehicle control center makes a mistake in judging and sends wrong instructions to the brake system, causing the brake plate to lose control. The second is that the iBooster system may have a very small possible design flaw; the third is that Tesla’s AutoPilot system and the iBooster system may have a very small matching flaw. According to the experience of another Zhang Che who advocated Qi (a pseudonym), he had twice responded to software problems with the customer service and asked to check the background data, but the other party’s reply was: too much background data, one minute of data It takes a long time to watch. “It’s not that they can’t find the problem, but they don’t act. Every time, they tell me to come back next time if there is a problem.” In addition, Tesla also provided a set of vehicle conditions 30 minutes before the accident: “The driver drove the vehicle normally, with more than 40 records of depressing the brake pedal, and the vehicle exceeded 100 kilometers per hour several times. And the situation of multiple braking stops.” Generally, brakes will have “thermal decay” problems. If the owner frequently re-presses the brakes, the overheated braking force will be severely reduced. However, it cannot be directly inferred that the main cause of the accident was the improper operation of the car owner. What is the final result of this rights protection storm requires more investigations. Without accurate and true data, all speculations are just conjectures. Female car owners are not alone. Since Tesla entered China in 2014, it has encountered various complaints every year. The female car owner just brought to the spotlight in an unexpected way the defects of product quality and after-sales service that had been concealed by Tesla’s aura for many years. How high is Tesla’s failure rate? Data shows that the number of Tesla Model 3 failures is as high as 236. This means that on average, every new Model 3 will have 2.36 failures within 2-12 months. The calculation method of this value is: the number of failures in one hundred vehicles = the total number of failures in the corresponding car system ÷ the sum of all the people participating in the evaluation × 100, which represents the number of failures per one hundred vehicles in a new car within 2-12 months, including failures , Abnormal noise, inconvenience and other problems. Compared to Xiaopeng P7’s 180, ideal ONE’s 134, Weilai ES6’s 56, and BYD Han’s 55, Tesla’s 100-car failure rate is significantly higher than these competing products. After Zhang Qi got the new car Model 3 in June last year, she often encountered some problems-for example, a new car of 350,000 drove on the road, sometimes shaking like a domestic car of tens of thousands of dollars; driving to work in the summer morning, the car will A layer of water mist appeared because the car automatically adjusted the air conditioner to a very low level, and it lasted all night; while driving in winter, the air conditioner only blows cold wind; sometimes the ears of the car cannot be turned on. This is nothing. Zhang Qi called the customer service before driving for repairs. The other party told him that the ball joint (also called universal joint, a kind of ball connection to realize the power transmission of different shafts) Mechanical structure) also repair him. “I wasn’t grateful to him at the time, it just made me think, why didn’t I say it early and recall it early? I only said it when I came to repair it? This attitude is very irresponsible.” Zhang Qi thought she was a very stubborn person before. People are very good at defending their rights, but facing Tesla’s after-sales service, they have no temper at all. The new car started to have various problems in less than a month. Zhang Qi has gone to repair 4 times so far, and the air conditioner has been overhauled 3 times. The first two times, the Tesla maintenance staff told him that there was no problem. Until the third time, the car screen displayed: “Due to a system failure, the temperature holder is unavailable”, the maintenance staff took it seriously. After changing the hardware, the air conditioner can be used later. The automatic control is still inaccurate, “Blow cold air when hot air should be blown”. Zhang Qi’s first three maintenance settlement statements At the end of March this year, when Zhang Qi drove this Model 3 off the elevated road, she smelled a pungent burning smell of the car. He and his friend sitting in the passenger seat were in a cold sweat. They thought it was a battery problem and the car might explode. They quickly parked the car on the side of the road for ventilation and called Tesla maintenance personnel. Two hours later, the maintenance personnel arrived at the scene, pulled the car to the maintenance point, and gave a “no problem” inspection result. During the overhaul, Zhang Qi once went to the car to pick up things. He found that his usual car phone charging cable was scorched. He asked a friend who worked in a car company to find out that this might be due to unstable battery, unstable voltage, and hot. There is a problem with the control system, etc., but Tesla inspectors still said that the car is okay and did not explain clearly-what faults will cause the data line to be burnt? What faults can cause the car to smell burnt? Compared to the car owner who has had a serious traffic accident, Zhang Qi is relatively lucky, but he has not dared to drive a Tesla since then. According to incomplete statistics from the Beijing Intelligent Vehicle Industry Innovation Center, Since 2013, Tesla has had hundreds of traffic accidents worldwide, resulting in a total of 175 deaths. According to statistics from the National Highway Traffic Safety Administration, Tesla has had 200 traffic accidents caused by “out of control” in the United States. Loss of control mainly refers to sudden acceleration, deceleration, and brake failure or steering wheel failure. In China, more than 20 Tesla vehicle accidents have appeared in the news in the past year. Although the number of traffic accidents cannot infer the direct fatality rate of Tesla, it can at least reflect that Tesla does have some unforeseen safety hazards. As Tesla’s sales increase, users have a deep understanding of the problems that arise during the use of vehicles. From the number and reasons of the recalled vehicles, we can also see the quality defects of Tesla vehicles. Among the many domestic new energy vehicle brands, Tesla has the largest number of recalls in the first quarter of this year. According to the announcement issued by the State Administration of Quality Supervision and Administration, a total of 5 new energy vehicle companies need to recall a total of 83,800 vehicles. Including 36,100 Tesla Model S and Model X, accounting for 43.1%, as well as BAIC New Energy’s EX360 and EU400 pure electric vehicles totaling 32,000, and Xiaopeng G3 vehicles totaling 13,399. Tesla’s latest recall of vehicles is mainly to update the software and replace the visual computing module in the central display (including the 8GB eMMC multimedia memory card). The eMMC cards of Model S and Model X produced before March 2018 experienced cumulative wear and tear, It will cause the central control screen to continue to be black. The central control screen integrates the most basic controls of the vehicle, including temperature, navigation, prompt sounds, etc., and most of the functions of the assisted driving system also need to be displayed on the screen. Although eMMC failure will not directly cause danger to the vehicle’s driving performance (acceleration, braking or steering), the software version of the vehicle is running too early, and the eMMC fails, the reversing image will not be displayed, and the external turn signal will not be able to be displayed during subsequent driving. Lights up, and even the defogging and defrosting functions of the windshield cannot be used. With this product issue alone, Tesla was required by the National Highway Traffic Safety Administration (NHTSA) in the United States to recall more than 130,000 Model S and Model X vehicles. Earlier, the German Automobile Administration (KBA) had also requested Tesla to recall about 12,300 Model X vehicles because of the shedding of the molded structure of the car body. In China, in addition to the recall, the relevant regulatory authorities have also interviewed Tesla twice, once in March last year, because some of the Model 3 vehicles should be equipped with HW3.0 chips (Tesla self-developed self-driving chips) , But only used HW2.5; the second time was in February this year, mainly for problems such as abnormal acceleration, battery fire, and remote vehicle upgrades. Why does Tesla always have problems? “Tesla’s current situation is that there are obstacles in the front and chasing after. The market can’t wait for Tesla to hand over a perfect product. If it waits for him to find out all the hardware and software problems, not only the capital can’t wait, but the users Can’t wait, the company has already closed down.” Zhang Xiang said. Tesla has actually passed the stage of building a car (Roadster) and building a good car (Model S), and now Tesla needs to build more good cars (Model 3). In the first two stages, Tesla relied on extreme technological innovation and cost control to highlight the auto market that has been dominated by established automakers for many years and gain a small market share. But in order to gain a firm foothold in the market before the auto giants increase their investment in electrification and intelligence trends, Tesla must rely on selling more products to stabilize the basic market in order to survive. Tesla has been accelerating its expansion in the past two years, building more super factories to expand production capacity and entering more emerging markets. This kind of speeding expansion is obvious in China-8 months to complete the construction of the factory and the off-line of the white body; last year, more than 410 super charging stations and more than 4,000 super charging piles were built in the country; last year, the production capacity was 150,000 vehicles. To achieve 550,000, it has tripled. Shanghai Tesla Factory During the production ramp-up period, Musk is also very clear about the problems behind it. He once said frankly in an interview at the beginning of the year that consumers are not advised to buy vehicles that are in a state of ramping production. “Either buy them at the beginning or wait until the production stabilizes.” Because it is difficult to guarantee that when the output rises sharply, It can achieve perfect details. For example, during the speed-up production process, it takes an extra one to two minutes for the vehicle paint to dry, but in fact there is not enough time to dry the paint. Although this is only an example of non-core components, it can at least show that there are still many omissions in Tesla’s manufacturing process. In Musk’s own words: “Yes, our production is like hell.” In the “Tesla China Chaos Revealed” released by Pinwan, it was mentioned that in order to complete the production, unqualified parts and components were installed on new cars; in order to make these products leave the factory, the solution was very simple and rude– Lower the factory standard. This kind of chaos in the production process is actually because Tesla pursues too much speed, and does not have the time and energy to confirm whether every detail is in place, and to carefully examine the possible omissions and omissions in the vehicle production process. Another point that causes product quality problems is cost control. Musk’s way of doing things is to achieve the best results at a very low cost. Zeng Yuqun, chairman of the Ningde Times, once complained, “Musk has been talking about cost issues all day, and I told him that I will definitely have a solution.” In addition to finding lower-priced suppliers, Tesla’s cost-saving method is actually to reduce unnecessary parts and reduce the cost of core components through system design and independent research and development. According to the dismantling of a Model 3 by the Zhihu Disassembly Laboratory, Tesla has done a lot of “cut corners” to reduce costs. “Switching from Model 3 to a minimalist interior to integrate the lights, rearview mirrors, and entertainment systems into the central touch screen, Tesla’s material cost is 1,000-2,000 yuan less than the competition. Take the 12.3-inch instrument as a For example, if the controller is included, the cost of this component is more than 1,000 yuan. Although the cost of the central control is saved, it increases the user’s interaction cost and sacrifices a certain degree of safety. …… The other is the highly integrated electrical architecture. Model 3 and Model Y divide the left, front, and right body controllers and the central computing unit by location. Although the unit cost of the controller has risen, the overall cost has dropped a lot due to the reduction in quantity. It is estimated that The saved material cost is equivalent to the latest smart phone. ” Tesla’s independent research and development of core technologies, such as chips, autopilot systems and other products, can reduce the occurrence of “stuck necks”, and the cost can also be greatly reduced, but the risks are also increased because of the products or technical routes independently developed by Tesla. Both require a certain amount of time for market verification. A typical example is that Tesla’s driverless technology mainly adopts the visual recognition route, which is to install a large number of cameras and sensors on the car to form a perception layer to identify and distinguish the environment around the car. Another technical route is the lidar route. For example, Xiaopeng, Weilai, Huawei, Uber and Baidu Apollo all choose to use lidar. The reason Tesla chose to take a different path is that it is too expensive. A set of lidar requires an additional nearly 50,000 yuan. Musk once bombarded lidar: “Stupid X only uses lidar!” Although lidar is more expensive, As long as the object exists, it can be detected without being affected by weather, light, etc. Truss once exposed the “ghost phenomenon”. For example, when a car drives to an unmanned cemetery, he perceives a lot of pedestrians around him; there is no car in the front and back, but it senses that there is a car. These are actually algorithmic flaws and cannot be quickly reacted in a special environment. For Tesla, it will take a long time to ensure that the error rate of the entire system is negligible. Write at the end The turmoil that Tesla is facing today is actually the sharp feedback from the market on the quality of its products and services. Tesla needs to divide responsibility and set standards for serious accidents. Regarding the rights protection of female car owners, although Tesla’s current attitude is to fully cooperate with third-party inspections. But Zhang Xiang said, “ At present, there is no third-party organization in the world that can clearly analyze the traffic accidents of smart cars. . Smart cars include a perception layer, a decision-making layer, and an execution layer. At present, third-party inspection agencies can only detect fuel vehicles. For the perception layer and decision-making layer, you need to get the schematics and software codes, and then get them one by one. Analysis, the workload behind this is huge. ” Exploring the truth and investigating responsibility is one direction, and the other direction is that we should think about why there is almost no third-party organization that can analyze the causes of traffic accidents in smart cars clearly? Why is the judgment standard for traffic accidents in smart cars still stuck in the era of diesel engines? When thinking about these issues, some people in the industry also gave concrete feasible solutions. The CEO of Ideal Motors wrote on Weibo that regarding ADAS and brake failure issues, government regulatory agencies can put forward the following regulatory requirements: 1. Vehicles with ADAS must be equipped with a driving recorder as standard; 2. When recording, the screen must display whether ADAS is running or not; 3. In addition to the display of the ADAS operating status, the corresponding basic working status of the accelerator, brake, and steering under the ADAS status should also be displayed. Human driving also displays the working status of these. He believes that this solution is not technically difficult, but it can provide relatively important evidence to reduce the difficulty for car owners to obtain evidence and the probability that manufacturers feel wronged. “If the car factory cheats here, it will directly stop the qualification for production and sales.” Do you have any constructive opinions behind the female car owners’ rights defense incident? Welcome to discuss~

Article | AI Blue Media Collection, Author | Wei Xiao In the face of force majeure, Huawei can only find another way out. Shanghai Auto Show on April 19. When the Tesla female car owner stood on the roof to defend their rights, Huawei’s consumer business CEO Yu Chengdong was also there. But obviously, he didn’t have much thoughts on this matter. He has more important tasks. The only time he has to go to the exhibition is not as good as a knife, such as taking a picture of the auto exhibits of major manufacturers with his mobile phone. This is one of the instincts of people in the automotive industry. Yes, both of Yu Chengdong’s feet have entered the automotive industry. If we say that five months ago, when Huawei internally adjusted the smart car solution BU to the consumer BG directly in charge of Yu Chengdong, the outside world did not have a clear perception. On April 20, one day later, Yu Chengdong personally proved this. On the same day at the Huawei flagship store on Nanjing Road, Shanghai, at the Smart Travel Huawei Smart Selection Tasting Conference, Yu Chengdong officially announced that Huawei will sell cars next. After that, there will be new car products based on Huawei Smart Selection to carry out dual-channel joint sales, which will be sold in Huawei’s offline flagship stores and Huawei Mall, and will be available for consumers to purchase and experience together with Huawei mobile phones, smart screens, PCs and series of smart selection . Yu Chengdong also became Huawei’s chief car sales officer, actively endorsing Huawei’s car sales on Weibo, and became active again. For technology companies such as Huawei, the new energy vehicles are inevitable. From a very early time, Huawei has begun to deploy in the fields of smart car systems, and has reached in-depth cooperation with a number of automakers. However, when it comes to Huawei nowadays, selling cars has a tragic meaning for self-help. Yu Chengdong said frankly: After many sanctions by the United States, Huawei’s mobile phone business has encountered very large supply challenges. As this kind of high-frequency, just-in-demand, massive, and high-value product, mobile phones can make up for this lack of sales, and the only thing that can be compared is smart electric vehicles. Although the sales volume is not as big as that of mobile phones, the unit price is high and the sense of value is high. Obviously, Huawei is still helpless in selling cars to a certain extent. After all, the 12 offline flagship stores and more than 5,000 experience stores are somewhat idle in the absence of sufficient supply support. Fill holes Huawei needs to fill in the deficiencies caused by the ban on its mobile phone business. According to Huawei’s 2020 annual report, Huawei’s growth has slowed sharply in 2020, with annual revenue of 891.4 billion yuan, a year-on-year increase of only 3.8%. In the previous three years, Huawei was able to achieve year-on-year growth of about 19%. Who slowed down Huawei’s growth? The answer is self-evident. It is the multiple sanctions, especially against Huawei’s rapid growth in consumer business in recent years. In 2016, when Yu Chengdong called out “kill Apple in three years and Samsung in five years”, the outside world thought he was talking unrealistically, but the facts proved that Huawei soon surpassed Apple in shipments. And it only took three years to close the distance with Samsung infinitely. According to Huawei’s 2018 financial report, Huawei’s consumer business surpassed the operator’s business for the first time, becoming the largest pillar of Huawei’s revenue. In 2019, Huawei’s consumer business achieved sales revenue of 467.3 billion yuan, a year-on-year increase of 34.0%, accounting for 54.4% of overall revenue. Among them, in the field of smartphones, in 2019, Huawei (including Honor) smartphone shipments exceeded 240 million units, a year-on-year increase of more than 16%, of which 5G mobile phones shipped more than 6.9 million units. According to the reports of market research institutions IDC and StrategyAnalytics, Huawei (including Honor) smartphone market share reached 17.6% in 2019, firmly ranking the top two in the world; 5G mobile phone market share is the world’s first. If it weren’t for the ban, in 2019, Huawei’s consumer business would be the number one in the world, and it would continue to advance in 2020. But unfortunately there is no if. In 2020, the growth rate of Huawei’s consumer business has fallen sharply. The financial report shows that in 2020, Huawei’s consumer business achieved sales revenue of RMB 482.9 billion, a year-on-year increase of only 3.3%, and its proportion in overall revenue also narrowed slightly to 54.2%. At the same time, in this financial report, Huawei’s consumer business did not disclose the shipment volume of Huawei (including Honor) smartphones, but highlighted Huawei’s “1+8+N” full-scene terminal connection. An obvious fact is that this year, Huawei’s mobile phone business has declined significantly. According to the 2020 global smartphone shipment report released by IDC, Huawei became the mobile phone manufacturer with the largest decline in shipments that year, with shipments of 190 million units, a year-on-year decline of 21.5%. At the same time, with the gradual escalation of the ban and the consumption of the original chip stock, in November of this year, in order to save itself, Huawei sold its sub-brand glory in desperation. This further means that Huawei’s mobile phone market share will continue to shrink. In Q1 this year, the signs are already very obvious. According to the Q1 global smartphone shipment report released by Strategy Analytics this year, the top five in the world no longer have Huawei, and the latter has become the “other”. For Huawei, this is indeed an unacceptable fact, but it has to be accepted. In the face of force majeure, we can only find another way out. Automobiles are just a piece of fat for Huawei to fill the gaps in consumer business. Not build a car From the industry’s perspective, Huawei’s participation in the automotive industry has a certain foundation. First of all, it has been in the field of Internet of Vehicles for many years. For example, as early as 2009, the research and development of in-vehicle modules was started; in 2014, Huawei established a car networking laboratory; in 2015, Huawei attracted eight manufacturers including Ericsson, Intel, Qualcomm, and Audi to establish a 5G car communication system. The technology alliance starts with the communication technology that it is good at, integrates AI chips, computing platforms, cloud services and other service modules, and then provides a complete set of services for smart car data. and many more. Based on the accumulation in the ICT field over the past years, Huawei Smart Car BU has penetrated into the core areas of smart electric vehicles, including five business segments: smart driving, smart cockpit, smart network, smart electric, and smart car cloud. Among them, in terms of electric drive system, vehicle power supply, battery management system, etc., Huawei has launched mass-produced products and realized commercial use. Secondly, as Yu Chengdong said, Huawei has brand endorsements and also has offline channels. Huawei’s consumer business has established 12 flagship stores and more than 5,000 experience stores around the world. With such channel advantages, Huawei can approach and get close to consumers by changing the geographic distance between traditional 4S stores and consumers. In Yu Chengdong’s words, Huawei’s car sales are not at the same level as Mercedes-Benz, BMW, and Tesla. These can indeed support Huawei’s car sales. But obviously, the market has another imagination about Huawei selling cars, that is, whether Huawei builds cars or not. Even if Huawei has given the answer many times. In 2019, Huawei clarified its positioning as a “incremental component supplier for connected cars” and an intelligent driving strategy of “focusing on ICT technology to help car companies build good cars”, and conveyed a strong signal to the outside world that it would not build cars. In November last year, when the smart car BU was assigned to Yu Chengdong to take charge of the consumer BG, Ren Zhengfei issued a statement emphasizing “who will build a car in the future, interfere with the company, be transferred out of the job, and find another job.” At the same time, when the official car sale was announced this year, Huawei executives including Yu Chengdong also reiterated: Huawei does not build complete vehicles, but intervenes in the industry as an ICT (information and communication technology) supplier. Huawei should not only help automakers build good cars, but also help automakers sell good cars. It is time and again to draw a clear line between car building. At least so far, it can be confirmed that Huawei’s entry into the smart electric car track is to become a supplier of China’s automotive OEM core component technology company. How to understand it, in the dimension of new energy vehicles, Huawei’s goal is to help Xiaomi build good cars! This is still a feasible way. The problem is, it’s hard to say if you can build a car in the future. After all, the Internet has not been a day or two since the overthrow of the previous plausibility.

WhatsApp is testing a Beta feature to speed up the playback of voice messages After a short activation, WhatsApp released a new version of Android beta 2.21.9.5 to disable this feature. This is arguably another surprise, because WhatsApp typically tests features for a few months before rolling out to public beta testers. This could be a buggy update from WhatsApp and has been quickly fixed. The interface for this version of WhatsApp has also been changed to better accommodate the new features. An icon appears right next to the voice message to perform accelerated operations that the user wants to hear again. In addition to playback acceleration, another feature also tested by WhatsApp is the ability to delete or make changes to a chat on just one active device without affecting any linked devices other. That is, changes or deletion of any chats through one handset will not be deleted from other linked devices. This is quite confusing because often performing a delete or change operation means that the content the user will not want to save on any device. If this feature is kept by WhatsApp, users will have to delete the chats multiple times on multiple devices. This feature is in line with what WhatsApp introduced previously, which is that each account can be importing up to 4 devices at the same time. However, the log out of all these devices is said to be in development, users still have to go to each device to remove the WhatsApp account. The new features that WhatsApp has introduced well for users to try out may see that it may be coming to many people soon.

Recently, Tesla owners’ rights protection at the Shanghai Auto Show continued to ferment.

On the 22nd, Tesla went on a hot search again. This time, the data was finally released.

30 minutes, over 40 brakes The final braking speed was 118.5 kilometers per hour!

On the afternoon of April 22, Tesla China released data for the 30 minutes before the accident. The data showed that in the 30 minutes before the accident, the vehicle had more than 40 records of depressing the brake pedal.

Tesla also made a text statement saying, When the driver stepped on the brake pedal for the last time, the data showed that The vehicle speed is 118.5 kilometers per hour . Within 2.7 seconds after the driver stepped on the brake pedal, the maximum brake master cylinder pressure was only 45.9 bar. After that, the driver increased the stepping on the brake pedal and the brake master cylinder pressure reached 92.7 bar. Immediately after the forward collision warning and automatic emergency braking function was activated (the maximum brake master cylinder pressure reached 140.7bar) and played a role , Which reduces the magnitude of the collision. 1.8 seconds after the ABS is applied, the system records the occurrence of the collision. After the driver stepped on the brake pedal, the vehicle speed continued to decrease, and before the collision, the vehicle speed was reduced to 48.5 kilometers per hour.

To sum up, the vehicle is running at a higher speed, and the driver starts to depress the brake pedal lightly. After that, the automatic emergency braking function is activated and played a role, increasing the braking force and reducing the impact of the collision. The braking system is normally involved in the work and reduces the speed of the car.

for The condition of the vehicle 30 minutes before the accident, Tesla described the following:In the 30 minutes before the vehicle accident, the driver drove the vehicle normally, with more than 40 records of depressing the brake pedal. At the same time, the vehicle exceeded 100 kilometers per hour many times and stopped repeatedly.

The relevant person in charge of Tesla said that he will unreservedly cooperate with the regulatory authorities to carry out in-depth investigations and openly accept social supervision.

Tesla said again late at night:

Will cooperate unreservedly in the investigation

On the evening of April 22, Tesla posted a post on Weibo stating that it once again promised that it would cooperate with the regulatory authorities to carry out in-depth investigations without reservation, and openly accept social supervision. With the consent of the customer, government designation or supervision, the three parties will jointly witness and conduct testing at any qualified and authoritative testing organization across the country.

The following is the full text:

   Zhengzhou City Market Supervision Administration:

   Receive data when both parties are present

   According to JiMu News, at 5:46 pm on April 22nd, related Tesla staff told reporters that they had already taken the official seal data to the Zhengzhou Municipal Market Supervision Administration on the morning of the 22nd, but the staff of the bureau suggested that, It is up to the owner of the car involved to dock and receive.

   

   According to Elephant News, on the afternoon of the 22nd, the husband of Ms. Anyang Tesla Chezhang told reporters that the staff of the Zhengzhou East District Municipal Supervision Bureau had notified the progress of the matter over the phone. Under the supervision of the Zhengzhou East District Supervision Bureau, go to the 4S shop to take the driving data away.

   

   Tesla’s person responsible for handling the accident said: “We have sent the data email to the customer. The customer has not answered the phone, and (we are) sent it to the email address the customer filled in when they bought the car through the company email.”

   New voice from Tesla rights defenders:

   Detection cannot keep up with technological development

   Soon after Tesla announced the situation one minute before the data restoration accident, another car owner, An Baojia, who participated in the rights protection, uttered a voice on Weibo, responding to why he did not perform a third-party identification. He said that “testing cannot keep up with technology” and it is difficult for authoritative appraisal agencies to be the dilemma faced by car owners after the current smart car controversy.

   

   On Weibo, Anbaojia first expressed joy that Tesla started to provide data. He expressed his gratitude to the motherland and human rights defenders. “There was no clear relevant legal basis before. (Background data) Tesla did not give it, and consumers had nothing to do. Consumers found the Consumers Association, and the Consumers Association had nothing to do. In the past few days, they have just received approval from their superiors for pure electric vehicles. Consumers have the right to know the traffic data generated during use and driving, and companies need to provide them unconditionally. With this provision, there will be disputes in the future, and it will be much easier for everyone to get the data.”

   It’s not easy to get the data, but Anbaojia raised a second question: “I don’t understand, and I can’t analyze the specific causes of the accident.”

   Anbaojia said: “There is a car friend who does related work, but he can’t analyze it. I don’t know which organization can interpret this data.”

   

   According to a report from the Beijing Daily, most of the vehicle appraisal agencies recognized by the relevant judicial departments were established earlier. Previously, they had basically conducted accident appraisal for fuel vehicles. Through consultation with several automobile testing agencies, the other party stated that they can perform hardware testing for vehicles, but if there are problems with software or systems, the existing technology of the agency cannot guarantee the detection.

   An industry insider who did not want to be named said that the agencies that conducted accident identification on fuel vehicles in the past may not be able to adapt to the needs of smart cars. The reason is that smart cars are built on the basis of computer technology, so the effect of car owners stepping on the brakes in the event of an accident is likely to be affected by system calculations. Therefore, traditional appraisal agencies can only appraise whether the brakes in the current situation are normal, and cannot appraise the brakes of the vehicle when an accident occurs. To completely restore the truth of the accident, car companies also need to provide background data.

   But even if car companies provide back-end data, whether the back-end data is complete and whether it has been modified has become a point of contention. In addition, a service staff member of a testing agency also said that, like many of Tesla’s emerging technologies, testing agencies now do not have equipment testing software. The most “authoritative” may be the manufacturer’s own analysis.

   This has caused the smart car accident to return to the embarrassing situation of the manufacturer’s “speaking of one family” without a third-party authoritative corroboration.

   Vice President Tao Lin resigned?Tesla: rumors

   After the Shanghai Auto Show’s rights protection incident was fermented, Tao Lin’s “no compromise” attitude on behalf of Tesla was criticized by the central media. On April 21, Tao Lin was absent from the Boao Forum for Asia, and the voice of her resignation began to circulate on social media.

   China Business News reported that Tesla responded: This is a rumor, and Mr. Tao is working normally.

   

The brake pad is a part that needs to be replaced periodically Ask: I am using a 2010 Volkswagen Scirocco. Lately when I step on the brake pedal, the pedal is deeper than when I first bought it. Is it a sign of brake wear and must be replaced? Le Huyen Chi (Thanh Xuan, Hanoi) Reply: Based on the conditions described initially, it is possible to predict that the brake pads of the vehicle are worn out and it is time to replace them to ensure safety. For vehicles, brake pads are a very important part of reducing vehicle speed, ensuring safety. If the brake pads are worn deeply, it will directly affect the slowdown or stop the vehicle. How fast or slow the brake pads wear depends on the way each person runs. However, the brake pads will wear out faster when used by a car in crowded cities, where the brakes are always pressed, constantly checking due to traffic congestion. Conversely, if the road is open, wide, less using the brake, the brake pads will wear longer. Some signs of discernible brake pads wear such as: Brake pedal often hits the floor, when the brake has phenomenon of vehicle or steering wheel shaking, hissing noise or metal sounds colliding due to worn brake pads … Then, it can be found through the brake warning lights that light up on the dashboard. It is recommended that the brake pads need to be replaced periodically, usually for 2 years or 50,000km, whichever comes first. If you regularly check the brake or move continuously in crowded road conditions, the time to replace this part will be sooner. However, because the safety system is very important, when there are strange signs related to the brake system, it is best to immediately take the car to a warranty center, genuine maintenance or a reputable garage for inspection. and soonest remedy.

Losing your temper when detecting a brake problem will only make it harder for you to handle the brake loss. So, you need to be very calm. Always observe and turn on the emergency lights Not panicking and not attentive to reducing the car speed. Instead, the first thing to do is to observe what is happening in front and behind the vehicle to avoid a collision. Immediately turn on the emergency lights, flash your headlights and use the papyrus continuously so that the vehicles traveling together pay attention to actively give way. Reduce the accelerator A vehicle that loses brakes is when the brake can not be used to control the vehicle’s speed. The most recommended treatment when the vehicle loses brakes is to remove the accelerator or reduce the accelerator pedal. However, if you are traveling in a busy road or going downhill, the driver should not remove the accelerator, just reduce the gas pedal. Because leaving the gas pedal to let the car run freely makes the car more likely to collide with other vehicles, causing more serious consequences. If the car loses brakes while Cruise Control is on, the driver should immediately turn off Cruise Control and reduce the throttle. Absolutely do not turn off the car engine When the car loses the brakes, never turn off the engine. Because turning off the engine will make the car lose steering power, making it difficult for the driver to control the car to avoid obstacles on the road. What’s more, turning off the engine means the car is no longer braked by the engine and transmission. It is even more dangerous for a car to fall into a free-flowing state under the force of inertia. Shift the car to low gear The driver can take advantage of the engine brakes by shifting the vehicle to low gear. For automatic transmission vehicles, the driver only needs to switch to semi-automatic mode, low gear mode or switch gears through the gearshift pad on the steering wheel. For manual gearboxes, the driver only needs to change the gear lever to 1 or 2. But a problem posed is that if the car is running at high speed suddenly, being forced to low gear can cause the car to break down, destroying the transmission system even more dangerous now. Some experts share, when dealing with a lost car, the car should not be put in low gear in the first place. Instead, switch the number by level or 2 levels. For example, if the car is in 5, it can go to 4 or 3, after feeling a more stable speed, continue to gear 2 or 1. Depress the brake pedal continuously Even if the vehicle loses its brakes, try to brake continuously. Because the vehicle may lose its brakes just because the vehicle only loses brake fluid pressure temporarily. Depressing the brake repeatedly can help regain the brake fluid pressure. When the soft feel brake pedal is pressed and the brake pedal is low, it is likely that the vehicle will lose its brake due to a malfunction of the oil line. At this point, you should depress the brake several times. Use the hand brake The handbrake is designed for use when the vehicle is stopped. But in an emergency, you can also use the handbrake to create braking force. However, if you use the handbrake, be careful that you only use the handbrake to brake when the vehicle is traveling at very low speeds. Because using the handbrake while the vehicle is running at high speed can cause the vehicle to lock, lose grip, slip long, leading to dangerous situations such as the vehicle being thrown, the vehicle loses control. Actively collide When the car has lost the brake, the driver should try to put the car on empty roads, rough roads, many stones … so that the vehicle can slow down or combine using a sagging method. In case of force majeure, the driver should choose to handle the last brake, which is to actively let the car crash into a safe obstacle to stop the car.

All objects falling into the air have terminal velocities depending on their size, shape and mass. The terminal velocity of an ant (6.4 km / h, according to the physics department of the University of Illinois) will be much different from the human terminal velocity (about 200 km / h). “For rats and any small animal, there’s really nothing dangerous. You can drop a mouse into a mine nearly 1,000 meters deep and when it hits the bottom, it gets dizzy and runs away. , provided that the ground is quite soft The air resistance acting on the moving object is proportional to the surface of the object.If the length, width and height of an animal are divided by 10, then the mass. Its amount is reduced by 1000 times while the surface area is reduced by only 100 times, so the air resistance for small animals is usually 10 times higher than the actuation force. Force is usually not an issue for insects, it can fall freely without danger, with the ability to cling. ” Michael Kaspari is an ecologist at the University of Oklahoma (USA), who has studied the aerial activities of wingless ants. Research shows that when ants are confronted with a predator, they jump in the air from tall branches and use their legs to steer their flight to the tree. The longer hind legs will allow the ant to travel through the air, preventing it from falling into places they deem dangerous. With this ability, it is possible that the ant has managed to cling to something before it falls to the ground, and whether it can grip or not, the ant will not die if it lands. The most ancient creatures still exist today It is thought that the earth currently has 10 million billion ants, despite the fact that they are killed a lot every day. According to biota, it is estimated that ants make up about 15-20% of the total number of terrestrial animals. Ants are animals belonging to the membrane wing, the layer of insects. Scientist Corrie Moreau and his French colleagues published a study that found ants appeared 140 to 170 million years ago. That means they are the most ancient creatures that still exist today, despite the intense fluctuations of the earth. Since then, it has been found that ants have a very high ability to survive in all weather conditions. Such survival is bestowed on nature, since they show no signs of consistent change. Which means it is very likely that an ant 170 million years ago and an ant now are no different. It is thought that the earth exists about 20,000 different species, with 4,500 families. They are found all over the earth. Even the extremely cold places are the poles of the earth, or the hot center of the equator. Ants come in many varieties, but the colors are usually just red or black. Especially, there is a species with white color added. Ants live in herds, with a quite separate social organization. Each nest has an average of about 100,000 children in a herd with a single mother (God ants, can live up to 30 years). Here, there is something like the way bees organize the swarms of life. The great majority of baby ants in the herd are worker ants (who only live 1-2 years) – such as the hardest and most hardworking workers on earth. The job of worker ants is to take care of queens, incubate eggs, transfer eggs, raise young ants, build caves, forage, guard … Few people know that all worker ants are female, but their reproductive organs are not fully developed, so they can never become God prejudices, but are forever just “cu-li” legs from birth. to death. Ants are considered the most powerful because they can carry food 10 times heavier than them. But to transport that heavy food, they have to use collective strength in coordination. Together, they carry the food they can find easily, when thousands of them work together. Ants are everywhere, anyone can see them or be stung by them, but few people know that they also have positive effects. The Masai people of eastern Africa have a habit of using ants as tools for wound healing. When one of the tribe was injured, they would capture a few large ones from the “army ant” group so that they would bite on either side of the wound, then remove the body, leaving only the ants on the wound. From there, the wound did not bleed and healed quickly. And interesting things about ants Ants are animals with a fairly sanitary life. Specifically the handling of the dead. When one is dead, the other ants in the herd together carry the dead ants out of the nest, with the sole purpose of keeping clean, avoiding infection or disease spreading. Worker ants will take care of carrying under the command of an ant that is believed to be responsible for the funeral of the flock. It was also surprising that ants were insects with a very advanced organizational system. Along with God ants, worker ants, and the commanding ants of burial, there are also “teacher” ants. Born, to have the necessary skills, they go through a learning process under the guidance of “teachers”. The “teacher” ants in the nest will teach the younger ants to do the necessary work. In the event that “students” learn slowly and “fail” on a test, they will be transferred to another job that requires less skills. Not only know how to find termites, but also know “breeding” to create a food reserve. They know how to feed insects such as aphids and moths to get the sweetness they produce. When it is time to harvest the sweeteners from the insect swarm, the ants “milk” using their antennae. It is extremely interesting to know that ant colonies carry a swarm of insects that they cultivate when moving to a new area. It is no different than humans taking cattle along to places where the grass is lush. People have talked about extraordinary in the ant world. They do not have ears but senses sounds from ground vibrations through the sensitive sensors on their legs. They have the ability to survive miraculously despite the extreme weather and climate. That is why ants are also one of the first organisms on earth to be sent to space by humans in experiments to conquer the sky. Ants have poor eyesight, in return they often use the earth’s magnetic field to guide their way. They are considered the smartest insects when there are more than 250,000 brain cells in the small head of ants. As a hard-working animal, ants are also said to be “great athletes”. If an ant was about the size of a human, then it could run at an average running speed of 55 km / h without ever getting tired. They can once again lift an object 50 times its weight with incredible strength.

In addition to a number of corporations such as Samsung Electronics, LG Electronics of South Korea and Huawei of China, most recently, Apple (the US technology corporation) also announced to recruit engineers to participate in research and development. to develop wireless technology next generation 5G. According to current research directions, the theoretical speed of 6G network will be one Tb / s, about 100 times higher than the theoretical speed of the 5G network (10 Gb / s). The new technology will also have broad coverage and be more energy efficient than the previous generation. Most importantly, 6G hopes to solve the limitations of current 5G networks. Specifically, even though it is considered as an Internet of Things (IoT) network, 5G still has a long way to go to achieve universal universality due to its limited ability to transmit signals at a height of many thousand meters. ground or deep below the ground or seabed. Meanwhile, 6G is research-oriented to meet both intelligent connectivity, deep connection, heterogeneous connection and everywhere. On the other hand, although 5G network has helped people make good use of artificial intelligence (AI) technology to optimize, distribute resources and process data, the forecast 6G network can do better by making AI becomes intelligent with the processing speed close to the human brain. 6G will integrate the new physical, digital, and services worlds to deliver stricter network performance metrics (KPIs) than 5G. However, the development of 6G networks is still just beginning and the end result will depend on speed of deployment and consensus on the technologies to deliver the ultimate standard. Experts say that the next 10 years will be a period for research and 6G will start to be commercialized from 2030. In the process of deploying previous generations of mobile networks such as 2G, 3G or 4G, Vietnam often lags behind the world. As for 5G networks, we are now starting to perform tests with the expectation of entering the first groups of countries to deploy the technology. But according to experts, in fact, Vietnam is still quite far away from the world in terms of research capacity and deployment methods in the telecommunications sector. Therefore, even though all countries have the same opportunity in terms of time to lead the research and deployment of 6G networks, not all countries have enough potential in science, technology as well as finance. join the race for core technology of 6G right now. Instead of racing to research core technologies, we should take advantage of other existing strengths to catch this wave, such as: Focusing on research and production of terminals for 6G; researching in-depth in the control and optimization of the 6G network system; research on AI technology for management system, data processing in 6G network system; blockchain security research (blockchain) … to solve the safety problem in the new network system. This may be a medium and viable market for Vietnam in the future.

Task Manager interface.

Turn off booting of some unnecessary programs

All you need is a built-in utility – Task Manager. This app isn’t just the place to stop nasty bots from refusing to shut down. The task manager can also help with boot time management. Open Task Manager by pressing Ctrl + Shift + Esc. Alternatively, press the Windows key, type “Task Manager” and select Task Manager from the search results that appear.

If Task Manager is in minimal view, click More details in the lower left of the window to see the full program.

In Expanded view, select the Startup tab. This section lists all the different third-party programs that are trying to launch at boot time. Virtually all of them can be turned off, but there are some possibilities you’ll want to leave them alone.

To figure out what to turn off and what to retain, see the Startup impact column. Any program classified as “High” or “Medium” must be a “candidate” for disabling. Some programs like sound card, password manager or something related to graphics card … must be kept. On the other hand, items like web browser helper or virtual private network (VPN) can wait to launch until you really need them.

To disable a program, select it, then at the bottom right of the window click the Disable button. Under the Status column you will now see that the program has moved from Enabled to Disabled. Continue as needed through the list of third-party programs.

Turn on Fast Startup

Windows 10 also has an option to start your computer faster, which is Fast Startup. When you turn on Fast Startup, Windows 10 automatically creates a Hibernate file for faster startup. How to enable “Fast Startup” as follows:

Step 1: Open “Control Panel”, then select “View by: Large icons”.

Step 2: Select the “Power Options” feature.

Step 3: Click “Choose what the power buttons do” in the left pane of the window.

Step 4: At the top, please click on the green text “Change settings that are currently unavailable”.

Step 5: Under “Shutdown settings”, check the box “Fast Startup”. Click “Save Changes” to save the settings on your machine.

Run Disk Cleanup and upgrade the drive

Alternatively, to add a bit more speed during boot time, you can also run Disk Cleanup. This will remove any junk files and make your SSD or hard drive work more efficiently.

If your computer is still using a mechanical drive, upgrade to an SSD card for faster boot. Installing an SSD is one of the simplest hardware upgrades you can make, and the difference it makes in terms of overall performance is impressive.

With these tips, you should see a significant improvement in your computer’s boot time, and the best part is that it doesn’t require any special third-party software downloads.

On the morning of April 15, the Department of Maternal and Child Health – Ministry of Health in collaboration with Vietnam Network of Social Organizations for Nutrition (SUN CSA) organized a workshop to promote the implementation of the Program “Nutrition care. The first 1,000 days of life are aimed at preventing maternal and child malnutrition, contributing to improving the stature and physical strength of Vietnamese people “.

The workshop aimed to guide nine provinces in the North to develop program implementation plans, and at the same time discussed to promote the development of detailed work plans and implementation of the program in the localities.

Dr. Nguyen Duc Vinh, Director of the Department of Maternal and Child Health, Ministry of Health, said that at present, many localities do not have plans to implement the program, so the provinces need to quickly implement the plan to have the best nutritional care for mothers and children, speed up the reduction of stunting malnutrition in children.

Currently, breastfeeding counseling is still limited. The incidence of anemia in pregnant women is high. Undernourished pregnant women still exist in many localities, but in big cities, pregnant women are gaining too much weight. There is still a gap in the quality of meals for children aged 6-24 months between geographical regions, economic and occupational conditions of mothers and ethnic groups.

Dr. Nguyen Duc Vinh, Director General of Maternal and Child Health Department, Ministry of Health, spoke at the workshop.

At the workshop, representatives of the units / localities discussed to develop a plan as well as organize the implementation of the first 1,000 days of nutritional care program in which identifying and analyzing priority issues. local, target development, selection of solutions, planning activities and program evaluation indicators.

After the seminar, localities will actively review and develop plans to submit to local authorities for approval and implement implementation to accelerate the reduction of stunting malnutrition in the country in general. As well as in mountainous areas, ethnic minorities in particular contribute to improving the physical stature of Vietnamese people, successfully implementing the goal of improving nutritional status of the Sixth Conference of the Central Committee. Program XII and Sustainable Development Goals (SDGs) by 2030.

On December 5, 2019, the Prime Minister issued Decision No. 1896 / QD-TTg approving the program “Nutrition care for the first 1,000 days of life to prevent maternal and child malnutrition, and improve the Vietnamese stature ”.

The program sets specific goals, to 2025, the rate of stunting in children under 5 years old is less than 20%; The rate of underweight malnutrition among children under 5 years old is less than 11%, particularly in ethnic minority and mountainous areas less than 15%; the proportion of children with a low birth weight (less than 2,500 grams) was less than 8%; the rate of anemia among pregnant women is below 23%, particularly in mountainous areas below 25.5%; 80% of mothers practiced early breastfeeding and 25% of mothers exclusively breastfed their babies in the first 6 months; 60% of mothers continued to breastfeed until their babies were 24 months old or longer; 70% of mothers gave children from 6-24 months of age correctly.

By 2030, the rate of stunting in children under 5 years old is less than 19%; the underweight malnutrition rate in children under 5 years old is less than 10.5%; the proportion of children with a low birth weight (less than 2,500 grams) was less than 7%; the rate of anemia among pregnant women drops below 20%, particularly in mountainous areas below 23.5%; 85% of mothers practiced early breastfeeding and 30% of mothers exclusively breastfed their babies in the first 6 months; 70% of mothers continued to breastfeed until their babies were 24 months old or longer; 80% of mothers give children from 6-24 months of age correctly.
