Mr. Ha Quoc Tri also asked Khanh Son District Party Committee to create conditions for Phuong Dai Private Enterprise Branch to continue developing new party members in the coming time. Jackie Chan

It creates an infinitely curved region of space-time, from which nothing can escape, not even light. Do black holes rotate? This is an interesting but not so simple question that I received in one of my recent lectures. To answer it completely and accurately, we need a clear understanding of the very verifiable properties of black holes as well as about the nature of rotation. To date, the concept of rotating black holes is not new. In fact, every object in the universe, once having a mass large enough to be spherical, will also have a rotation. Since mass exerts gravity, every object tends to compress itself – because its parts attract each other. For small masses, this gravitational compressive force – commonly known as centripetal gravity – is so small that it cannot exert any effect on the object, because it is simply an intermolecular force of cohesion. substance – especially solids – is much larger than it is. But with very large masses, on the other hand, the force of gravity is so great that matter will rearrange until it becomes spherical. That is, the state in which the force of gravity directed at the center of the object from all directions is equal to each other. That’s how every object as large as a planet or a star gets its spherical shape. At the same time, when there is such a large mass, another problem arises, and also related to gravity. Since no single star or planet is perfectly uniform, in fact the gravitational forces in their different regions are unequal. This difference is the main reason they oscillate, and hence the rotation. Thus, all large objects in the universe rotate because of their own gravity. What about black holes? The most common types of black holes known to scientists today are stellar-mass black holes. It is formed from the late-life contraction of the cores of massive stars. These stars are usually at least 8 to 10 times the mass of the Sun. Towards the end of their lives, their cores shrink very rapidly because the fusion reaction no longer produces enough energy to resist the contraction of that enormous mass. This sudden contraction causes an explosion that is considered one of the most violent events in the universe” supernova explosion. This explosion tore apart the stellar shell that was previously in the state of a red supergiant. The remaining core of the star shrinks and collapses to become a black hole. All stars rotate on their own axis (our Sun, for example, has a rotation period of more than 25 days). It is not difficult to speculate that something formed from a rotating stellar core would also have to rotate, because that momentum is simply still there. The same is probably true of supermassive black holes – black holes with masses ranging from hundreds of thousands to billions of times the Sun, located at the center of most galaxies ever observed. In fact, when the first image of a black hole was released in 2019, scientists were able to see the spirals of the accretion disk surrounding the black hole. It shows that the giant accretion disk is rotating, not fixed. Just like the fact that all the stars in each galaxy are constantly moving around the center of the galaxy (for example, our Sun takes about 230 million years to complete one full circle around the center of the Milky Way). Two things need to be clarified before concluding that the black hole rotates on its own The entire initial mass of the black hole – in theory – is packed into an extremely small singularity. It is so small that it can mathematically be considered sizeless. That singularity has a certain radius (Schwarzchild radius) known as the black hole’s event horizon, but it is just a region of pure space-time, not an object like it has a surface. like a star or a planet. As such, it is difficult to consider something with no dimensions, or a boundary without a surface, to be rotating, since there is simply no alternate motion of points to a particular surface. No radiation comes out from within the event horizon, which also means that all information inside a black hole is unknown. If matter were indeed crushed and completely collapsed into a single point, the space within the event horizon could itself be a place of absolute uniformity, i.e. no rotation would occur due to the difference. interesting. With these two points in mind, don’t forget that what we see spinning is itself just the accretion disk surrounding the black hole. Of course, one can also calculate the rotational speed of an accretion disk based on its mass when taking into account as well as when not taking into account the presence of a black hole at the center, from which to compare and predict. It looks like the black holes in those places are spinning very fast. Even so, given that we don’t know anything about what lies within the event horizon, or even something specific happening at its very edge, concluding that black holes are indeed rotate or not and how fast they rotate is still too early. Likewise, the charge of a black hole is also a purely theoretical concept and is calculated from solving Einstein’s equations. There is no way for us to verify if an electric charge really exists after being swept inside the black hole’s event horizon. In the future, to know more about this information, we will need to look forward to new generations of telescopes and new methods to image and track more black holes with much greater detail. compared to what there are today.

On June 15, the Department of Health of Ninh Binh province deployed the second phase of COVID-19 vaccination including 14,330 doses for priority subjects according to Resolution No. 21 of the Government; of which there are more than 8,000 doses for the 1st injection, the remaining more than 7,000 doses are for the 2nd injection cases when they are eligible for injection 8-12 weeks apart.

Dong Thap province deployed Astra Zeneca vaccine for the 3rd phase of COVID-19 disease, with 30,000 doses allocated from the Ministry of Health, of which 27,000 doses are expected to be injected in the first dose and 3,000 doses in the second injection. prescribed in accordance with Resolution 21/NQ-CP of the Government, including: Subjects who are absent or delayed in injection in the 2nd round; frontline force for epidemic prevention and control; essential service providers; Teachers and administrative units often come into contact with many people. Master Tran Van Hai – Director of the Center for Disease Control of Dong Thap province said that this activity was carried out urgently and earlier than the original plan from July 5. Dong Nai province will use 17,450 doses to inject the second dose for more than 20,000 people. The remaining 11,450 doses will be administered to about 13,500 people in priority groups. The duration of the second phase of COVID-19 vaccination in the province is expected to last from June 12 to June 30. Vaccination sites at 170 health stations in communes, wards and towns… COVID-19 vaccine fund received VND 5,126 billion According to the Management Board of the COVID-19 Vaccine Fund, as of 5pm on June 15, the fund has received 5,126 billion VND (including foreign currency conversion) with a total of 306,791 organizations and individuals contributed. Minister of Finance Ho Duc Phuc said that the COVID-19 vaccine fund operates not for profit, uses capital for the right purposes and in accordance with the provisions of the law, ensuring publicity and transparency. Economical, efficient. The Fund is subject to the inspection, inspection and audit of financial activities by state management agencies in charge of finance and State Audit; supervision of the Vietnam Fatherland Front and the community. According to the Ministry of Finance, to vaccinate 75 million people, about 25,200 billion VND is needed; in which the budget has already prepared more than 14,000 billion VND and needs about 11,000 billion VND more. Japan will provide 1 million doses of COVID-19 vaccine to Vietnam On June 15, Japan’s Foreign Minister Toshimitsu Motegi announced that the country would directly and freely provide 1 million doses of a domestically produced COVID-19 vaccine under license from AstraZeneca Plc. (UK) for Vietnam. Speaking at a regular press conference in Tokyo, Minister Motegi said that Japan has received requests for vaccine support from many countries and regions. According to Motegi, Japan made the decision to grant a COVID-19 vaccine to Vietnam based on a comprehensive review of the epidemic situation in Vietnam, the shortage of vaccines and the relationship between Vietnam and Japan. Minister Motegi said the above batch of COVID-19 vaccine will be shipped from Japan to Vietnam on June 16. Earlier, on June 2, Prime Minister Suga Yoshihide announced that Japan would provide 30 million doses of COVID-19 vaccine to other countries. In addition to providing vaccines, Japan also plans to help developing countries build cold storage chains, allowing the transport and storage of vaccines at low temperatures. On the afternoon of June 15, Vietnam had 213 new cases of COVID-19 On June 15, Vietnam recorded 402 new cases. As of 6pm on June 15, Vietnam had a total of 9,566 domestic cases and 1,646 imported cases. Number of new cases from April 27 to now: 7,996 cases, of which 1,765 patients have been announced to be cured. Screening test for people with COVID-19. Photo: VNA. There are 23 provinces (Yen Bai, Quang Ngai, Dong Nai, Quang Ninh, Quang Nam, Quang Tri, Thua Thien Hue, Nam Dinh, Hoa Binh, Tuyen Quang, Son La, Ninh Binh, Thanh Hoa, Thai Nguyen, Hung Yen, Hai Phong, Tay Ninh, Gia Lai, Bac Lieu, Dien Bien, Dak Lak, Dong Thap, Tra Vinh) have not recorded new cases for 14 days.

(Source: petrovietnam.petrotimes.vn) Despite being at the peak of the COVID-19 epidemic, in the early days of this June, Thi Vai LPG filling station (TNTV) of Vung Tau Gas Processing Company (KVT) once again set a new record with 89 tank truck and total LPG export volume is 1,512.47 tons/day, compared to designed capacity of 1,400 tons/day. The diverse operating interface has many potential risks related to the disease, but this “challenge” has been approved by PV GAS Vung Tau Terminal (KCTV) and Vung Tau Gas Processing Company – a member unit of the Corporation. PetroVietnam Gas Corporation (PV GAS) overcame by effectively implementing the “dual goal” of preventing, combating and responding to the epidemic, while maintaining continuous and effective production and business activities. Along with a system of clear and specific procedures and regulations, employees at PV GAS Vung Tau’s warehouses are always aware of their responsibilities in complex disease conditions. The plan to maintain production and business during the new outbreak was activated soon. As a result, Vung Tau Gas Processing Company has actively implemented activities under strict safety and security conditions; creatively apply processing directions to create the highest efficiency, serving the needs of customers to the fullest. Previously, PV GAS Vung Tau Port Warehouse also regularly broke LPG export records by itself when applying and continuously improving methods of coordination and management of the delivery system. Specifically, in 2019 there were 3 times to raise the record and in 2020 there was 1 time to reach a new record. With the record continuing to be recorded at the beginning of June, this represents the unit’s efforts in disease prevention in parallel with socio-economic development. This is also a practical activity towards the 20th anniversary of operation PV GAS Vung Tau Port Warehouse ./.

People wait to be vaccinated against COVID-19 in Tokyo, Japan on May 24, 2021. Photo: AFP/VNA According to the Vietnam News Agency correspondent in Tokyo, speaking at a press conference after announcing the extension of the state of emergency for nine provinces on May 28, Prime Minister Suga Yoshihide emphasized his determination to deploy COVID-19 vaccine vaccination for people under 65 years of age, including those with underlying medical conditions, starting at the end of next month. Regarding vaccine supply, Prime Minister Suga affirmed that the government will ensure the necessary amount of vaccine for the vaccination campaign with 100 million doses expected to arrive in Japan by the end of June and another 100 million doses to be added. September. The specific vaccination time of each locality will be decided on the basis of the positive results of vaccination for people over 65 years old, and the location can also be expanded to implement in the workplace. jobs or universities. Prime Minister Suga said the Japanese government will do its best to soon return to normal life for the people with efforts to speed up the pace of COVID-19 vaccination. Currently, the vaccination rate is around 400,000-500,000 times/day, but from June it will be increased to 1 million times/day. Japan started the COVID-19 vaccine vaccination campaign in February, basically giving enough shots for medical staff who are the frontline force against the epidemic. With the operation of two large-scale vaccination centers in Tokyo and Osaka from May 24, as well as positive results from the negotiation to buy vaccines, the Japanese government is expected to be able to vaccinate the entire population. the entire population from the end of June, 1 month earlier than originally planned. In addition, children will also be included in vaccination after the Japanese Ministry of Health, Labor and Welfare (MHLW) has licensed Pfizer’s vaccine to expand the vaccination age from 12-15 years old. . Meanwhile, the pharmaceutical company Modena has also submitted clinical data to the MHLW and may be approved for injections in subjects 12 years of age and older next month.

Climate change is one of the main causes of extinctions worldwide. 5 mass extinctions Dinosaurs became extinct in the Jurassic, more than 200 million years ago. * Ordovician-Silurian Extinction: About 440 million years ago The first mass extinction on Earth occurred at a time when organisms such as corals and shellfish filled the world’s shallow waters but had yet to venture to land. Life itself has begun to spread and diversify, first appearing around 3.7 billion years ago. But about 440 million years ago, a climate change caused sea temperatures to shift, and much of the life in the ocean died out. At the end of the Ordovician, mass glaciations covered the southern supercontinent, Gondwana. According to a study published in the journal Oceanology, glaciation on this scale has stripped away high proportions of the world’s water and dramatically lowered global sea levels, depriving the world of vital habitats. species, destroying the food chain and reducing fertility, according to a study published in the journal Oceanology. However, not all scientists agree with this. According to National Geographic, other theories suggest that the toxic metal may have dissolved into seawater during periods of oxygen depletion, wiping out marine life. Other scientists suggest that a gamma-ray burst from a supernova ripped through a giant hole in the ozone layer, allowing deadly ultraviolet radiation to kill life below. According to APS News, there is a Another theory is that volcanoes are the cause. * Late Devonian Extinction: Over 365 million years ago The Devonian period witnessed the rise and fall of many prehistoric marine species. Although by this time animals had already begun to evolve on land, most of life was swimming through the oceans. Until vascular plants, such as trees and flowers, have the potential to cause a second mass extinction. According to the BBC, as plants develop roots, they inadvertently transform the land they inhabit, turning rocks and rubble into soil. This nutrient-rich soil then runs into the world’s oceans, causing algae to bloom on a massive scale. These blooms essentially created giant “dead zones,” areas where algae take oxygen from the water, suffocating marine life and wreaking havoc on the marine food chain. Species that could not adapt to reduced oxygen levels and lack of food died. However, this theory is still being debated, and some scientists believe that volcanic eruptions are responsible for the drop in oxygen levels in the ocean, according to a study in the journal Geology. A species of sea monster that has been wiped out from the world’s oceans is the 10 m long armored fish called Dunkleosteus . * Permian-Triassic extinction: ~253 million years ago This extinction event is the largest event that has ever occurred on Earth. It wiped out about 90% of all species on the planet and wiped out the reptiles, insects and amphibians that roamed the land. What caused this catastrophic event was a period of rampant volcanism. According to the Sam Noble Museum in Oklahoma, in the ocean, rising levels of carbon dioxide dissolve into the water, poisoning marine organisms and depriving them of their oxygen-rich water. Rising sea temperatures also reduce oxygen levels in the water. Corals are one of the hardest hit groups of marine life – it takes 14 million years for oceanic reefs to rebuild as they once were. * Triassic-Jurassic Extinction: About 201 million years ago The Triassic period was the time when dinosaurs began to inhabit the world. Unfortunately, many volcanoes were also erupting at that time. While it’s still not clear exactly why this fourth mass extinction occurred, scientists suggest that massive volcanic activity occurred in an area of ​​the world now covered by the Atlantic Ocean. cover . Similar to the Permian extinction, volcanoes released huge amounts of carbon dioxide, causing climate change and devastating life on Earth. Global temperatures rise, ice melt, sea levels rise and acidification. As a result, many marine and terrestrial species became extinct; These include large prehistoric crocodiles and several species of flying pterosaurs. All dinosaurs were killed in the fifth mass extinction. Scientists estimate that many species that can fly, burrow or dive into the depths of the ocean survive. For instance, the only true descendants of dinosaurs living today are modern-day birds – more than 10,000 species are thought to have descended from survivors. Is the 6th going? According to The Conversation, scientists define a mass extinction when about three-quarters of species die out in a short geological time, i.e. less than 2.8 million years. Currently, humans are in the early stages of the latest mass extinction, which is happening much faster than any other species. According to the International Union for Conservation of Nature (IUCN), since 1970, populations of vertebrate species have decreased by an average of 68% and now more than 35,000 species are considered threatened with extinction. During the 20th century, as many as 543 species of terrestrial vertebrates became extinct, according to a research paper in the journal PNAS. Since the beginning of the industrial revolution in 1760, humans have been a major factor in Earth’s current environmental crisis. From greenhouse gas emissions and ozone depletion to deforestation, plastic piling and the illegal animal trade, humans have been proactively depriving the world of some species and threatening many others. Ecotourism is an industry that drives conservation efforts around the world, but it is on the verge of collapse since global travel restrictions were introduced. Without tourist income, conservationists are having a hard time protecting vulnerable species from poaching, while the COVID-19 pandemic is intensifying. The New York Times reported. Rhinos in Botswana, feral cats in South America and tigers in India have all been targeted in the past year. In the context of the current pandemic, the wildlife market has become the focus of attention for not only being environmentally irresponsible but also potentially endangering human health through infectious diseases. from animals to humans – such as the COVID-19 pandemic. These markets, which trade in live exotic animals or products derived from them, are found all over the world. For example, bear farms in Asia trap 20,000 Asian black bears for bile, leading to a decline in wild populations. Another potential solution to combat extinction could be the cloning of species. In February 2021, scientists revealed they had successfully cloned a black-footed ferret from an animal that died more than 30 years ago. Native to North America, these small mammals were thought to be extinct until a small colony was found in the early 1980s, where they were engaged in breeding and reintroduction programs. across America. The cloning process is similar to that of Dolly the sheep in the early 1990s.

Orchid nursery nursery Di Linh – the result of the project of breeding In-vitro fake crane orchids by the Center for Science and Technology Application (under the Department of Science and Technology of Lam Dong Province). The technique of propagation by plant tissue culture (In-vitro) is no longer strange in Lam Dong province in general and Da Lat city in particular. The application of this technology to propagate the species of Orchid Di Linh was first deployed by the Center for Science and Technology Application. The project was completed, completed and accepted by Mr. Phan Quoc Chinh, Deputy Director of Lam Dong Center for Science and Technology Application and his colleagues. To select the original source of quality seed, the people who carried out the project had to collect Gia Hac Di Linh orchids in Da Lat city and Di Linh district, in orchid gardens that met strict standards. Sampled plants must have an average height of 30-40 cm, have 14-16 pairs of leaves, average trunk diameter of about 4mm and be planted in plastic or terracotta pots. Each tree has 4-5 fruits and the physiological ripening rate is not equal. Selected fruits that should be dark green and physiologically ripe, of the specified size, without cracks, were collected for inclusion in the sample. After cleaning and disinfecting, samples of Di Linh falcon will be propagated in-vitro according to the following summary procedure: Initial culture stage to create buds and clusters of buds; rapid multiplication stage; rooting stage to create a complete plant. These three stages take about 28 weeks, then the seedlings (5cm tall, 4cm long roots, good growth, dark green leaves) are brought to the nursery to plant and take care of. After about 24 weeks, the plant can be grown with a height of 5-7cm, with 4-5 leaves. According to Mr. Phan Quoc Chinh, plants grown in an In-vitro environment must ensure the conditions of temperature, humidity and light intensity according to certain cycles. In addition to the results of creating a series of fake crane orchids, the project also built a standard process for propagating this plant by the In-vitro method and can be transferred to other units. “During the implementation, we tried to add ripe banana pulp, coconut water to the culture medium. The results showed that shoot formation and shoot growth also increased faster than normal, “- Mr. Chinh said. Very cheap price Seedlings of Phalaenopsis orchids are extracted and put into nutrient bags to be raised in the laboratory before being sent to the nursery. After completing the In-vitro propagation process, the first 500 orchid seedlings were brought to the nursery at the Don Duong Experimental Station (Don Duong District) and continued to be tested on many different types of media within a short period of time. 3 months. As a result, the rate of plants living outside the nursery reached 90%. Among the types of substrates put into the experiment, the coir fiber medium helped the plant grow best, the height of the tree reached 5.6 cm; The root length is 3.70 cm, the survival rate is 95% and the tree has a large stem, dark green leaves, many leaves. According to Mr. Nguyen Nhu Chuong, Director of Lam Dong Center for Science and Technology Application, after the acceptance of the project, the Center continues to propagate about 3,000 plants to supply domestic and foreign markets at an export price. selling for only about 25,000 VND/seedling. “The method of tissue culture in the laboratory makes it possible to propagate many times larger numbers than natural breeding. Therefore, the price that the Center is selling to the market today is normal,” said Mr. Chuong. From the research results of the topic, Lam Dong Center for Applied Science and Technology has developed a baseline standard for the Di Linh Giac Giac orchid seedling and was continued by the Sub-Department of Cultivation and Plant Protection. take. Thereby, the genetic resources of rare forest orchids originating in the locality are preserved and developed. A Di Linh Fake Orchid is eligible for sale for 25,000 VND / tree, very cheap compared to the current market. According to Mr. Ho Anh Dung, Vice Chairman of Da Lat Flower Association, the quality of In-vitro seedlings will ensure higher uniformity and superiority compared to traditional methods, serving the conservation of seed resources. and commercial purposes. The first-line mother tree has been carefully selected, which will help the seedlings to preserve the best characteristics of the mother plant, not only the Di Linh orchid but also precious plants such as Ngoc Linh ginseng, Camellia flower .. .

After irradiation, samples of the fake crane orchids were taken to the separation room to be cultured in nutrient solution for a certain time. (Photo: Nguyen Dung/VNA) In Lam Dong – the “capital” of high-tech agriculture of the country, the application of new science and technology in agriculture is increasingly widespread. Especially for the plant breeding industry to preserve rare genetic resources as well as to develop commercial varieties of these plants. Wild Orchid Di Linh is one of such trees. They are not only mass-produced, but also irradiated to create mutations on demand. Di Linh fake crane – a “famous” orchid of orchid players inside and outside Lam Dong province, often sought to buy with many different prices. However with In-vitro technology As modern as it is today, for the first time, the Center for Science and Technology Application (Lam Dong Department of Science and Technology) has successfully studied the process of mass propagation of this plant. Mass breeding The technique of propagation by plant tissue culture (In-vitro) is no longer strange in Lam Dong province in general and Da Lat city in particular.

Medical declaration via Zalo is considered a method of saving time and reducing the risk of infection. People just need to do the declaration steps at home instead of going to a health station, hospital or public place. In particular, people do not need to declare many times. Once completed, residents will receive a QR code confirming that they have declared medical information to provide security and medical staff at the destination or at the disease control checkpoint. Medical declaration feature on Zalo page “Quang Nam Provincial Police”. In Ha Nam province, before large-scale deployment, all officers and soldiers of the provincial police force made electronic medical declarations through Zalo “Ha Nam Provincial Police”. In addition, propaganda is also promoted so that people know and accompany in electronic declaration. Meanwhile, in Hai Duong, since the Covid-19 epidemic re-emerged, the official account “Hai Duong Provincial Police” on Zalo is used to send all tracing notices and search for people related to the Covid-19 cases in the province, supporting people to make medical declarations during the period of social distancing. Hai Duong province continuously implements strict epidemic prevention measures. The rapid implementation of the “Medical declaration” feature on the Zalo page by the provinces in order to proactively and effectively implement the tracing and timely detection of cases at risk of infection and disease, and at the same time contribute to the common sense. hands to prevent and control the Covid-19 epidemic in the area. For provinces and cities that have not yet implemented the “Medical declaration” feature on the official Zalo page, people can still make a quick and safe declaration on Zalo by searching and paying attention to the Zalo “Prevention of Corona Virus” page. , select the built-in “Medical declaration” and complete the declaration. For locations that require scanning a QR code to declare, people go to the Zalo application and select the QR code icon in the right corner, then complete the required declaration. The online medical declaration feature is Zalo’s attempt to bring technology to the community. Actively declare health to help protect yourself, your family and the community. Previously, the National Steering Committee for Covid-19 Prevention and Control issued Official Dispatch No. 3751/CV-BCD to ministries and ministerial-level agencies, agencies attached to the Government, People’s Committees of provinces and cities on promoting Electronic medical declaration for Covid-19 prevention and control by QR code and applications.

This is a historic milestone that makes China the second country to successfully launch a probe on the Red Planet. In the past, only NASA has succeeded in landing and operating probes on the red planet. (The Soviet Mars 3 spacecraft landed on Mars in 1971 and remained in contact for only about 20 seconds.) The landing took place at Utopia Planitia, a flat land on Mars and the same area where NASA’s Viking 2 rover landed in 1976. After landing, the lander dropped the Zhurong rover – Powered six-wheeled robot named after the god of fire in ancient Chinese mythology. The spacecraft carries an integrated toolkit, including two cameras, a Mars subsurface probe radar, a Mars magnetic field detector and a Martian meteorological tracker. “This is the hardest place to land in the solar system,” said Emily Lakdawalla, author of “The Design and Engineering of Curiosity.” China’s success in its first attempt indicates that it is one of the most capable space agencies.” The European Space Agency also tried to land on Mars in 2003, but its Beagle 2 probe had problems. The ExoMars Schiaparelli spacecraft – another ESA (European Space Agency) effort also crashed in 2016 after software mis-estimated its altitude during a landing attempt. Photo: The Verge The Tianwen-1 spacecraft launched from Wenchang Launch Site in Hainan Province, China last July, embarking on a seven-month trip to Mars. China said that “Tianwen-1 has been operating normally since it entered the orbit of the Red Planet,” the China National Space Administration (CNSA) said in a statement on the morning of May 15. CNSA revealed that Tianwen-1 has collected a large amount of data and photos taken from the orbit of Mars. Andrew Jones, a journalist covering China’s activities in space, said that Tiawen-1 has been exploring the Utopia Planitia landing site for more than three months while orbiting Mars. Now, after a successful landing, the Zhurong rover will embark on a mission that will last at least three months to study Mars’ climate and geology. “The main mission of the Tiawen-1 mission is to conduct a comprehensive and extensive survey of the entire planet using orbiters and to bring the probes to surface locations of great scientific interest. focused to conduct detailed investigations with precision and high resolution,” the leading scientists wrote in Nature Astronomy last year. It is known that this expedition vehicle weighs about 240kg, nearly double the weight of China’s previous Yuto Moon. The CNSA said last month: “The Mars rover Zhurong is hoped to ignite the fire of China’s interplanetary exploration and guide humanity into the vast unknowns of outer space.” Photo: The Verge Before Tiawen-1 successfully landed on Mars, the United States also successfully landed 5 rovers on the surface of the Red Planet. More recently, on February 20, 2021, NASA’s Perseverance probe passed through the atmosphere of Mars and landed on the planet on a historic mission to recover rocks to help answer the question. whether life ever existed on Mars. Although this CNSA project is more than four decades behind NASA, this success of China shows that its space engineers are rapidly closing the gap with the US. Tiawen-1 marked a big step for China in the field of space exploration. Previously, China also became the first country to successfully land and operate a probe in the dark side of the Moon in 2019. Recently, China also successfully launched its first core module. Chinese space station. In the future, this will be inhabited by groups of astronauts in space. Earlier this year, China, in partnership with Russia, announced plans to build a space station on the surface of the Moon.

After Tucson is listed in the future, the commercial vehicle autonomous driving market in which it is located may also enter the eve of large-scale landing. Image source: Tuworm Creative At a time when passenger car autonomous driving is not yet mature, the field of truck autonomous driving has given birth to “the world’s first autonomous driving stock”. On April 15th, Eastern Time, the self-driving truck brand “Tucson Future” officially landed on Nasdaq. The opening rose by more than 3%, and the opening price was US$40.25, slightly higher than the IPO price (US$40), but it began to fall after rising to US$41.5, and closed at US$40 on the day, which was flat compared to the IPO issue price. It is foreseeable that after Tucson is listed in the future, the autonomous driving track will be sought after by more capital, and the commercial vehicle autonomous driving market in which it is located may also enter the eve of large-scale landing. In response to more issues related to future business planning after the listing, Times Finance tried to contact Tucson Future, but as of press time, no response has been received. Is the “first share of autonomous driving” worth US$8.787 billion? The autonomous driving track is divided into the passenger car market and the commercial vehicle market. The former, such as Baidu, Didi, etc., directly face C-end consumers, with Robotaxi as the final commercial landing scene; The specific business scenario is unmanned autonomous driving. Tucson Future was established in 2015. In the future, it will mainly provide customers with computer vision-based commercial L4 autonomous driving solutions, high-speed scenes and unmanned transportation solutions for container trucks in the port. Headquartered in Shanghai, with branches in the United States and Beijing, the main market is currently in the United States. Tucson’s future business model has been relatively clear. In July 2020, it launched its own driverless freight network “AFN”. The ecosystem consists of fully automated semi trucks, high-definition digital map routes, strategically placed terminals, and a cloud-based proprietary autonomous operation supervision system TuSimple Connect. composition. Based on this network, Tucson’s future service models mainly include three types:

Cooperate with the shipper. In the future, Tucson will use its own unmanned vehicle fleet operating in an unmanned network to provide shippers with unmanned freight services calculated by mileage.

Cooperate with the carrier. Carriers can purchase driverless trucks, operate them in the driverless freight network, and connect to Tucson’s future driverless systems when necessary.

Fleet. Fleet owners can buy and operate their own fleet of driverless trucks. These unmanned trucks will operate in the unmanned freight network according to the mileage-calculated charging mode.

Since its establishment, Tucson has gone through 10 rounds of financing in the future, and the disclosed amount of E-round financing is 350 million yuan. In addition to the founding team, Tucson’s future largest shareholder is Sina affiliate Sun Dream Inc., which accounts for 20% of Class A shares.

As the first stock of autonomous driving, what is the market value of 8.49 billion U.S. dollars? “From the perspective of Tucson’s current financial indicators such as revenue and profit, as well as its commercialization capabilities, the market value of US$8.49 billion is relatively high. However, Tucson’s future track will have high growth, and market competitors will be relatively If there is less, there is more room for imagination in the future.” Major General Ding, an IT Internet observer, told Times Finance and Economics.

The capital market has always valued autonomous driving very high. Both Baidu Autopilot and Waymo are currently valued at around US$40 billion. However, the market for autonomous driving passenger cars is very large, and the non-commercial vehicle market can match them.

Compared with its peers, Pony Zhixing, which is also on the truck autonomous driving track, is valued at more than US$5.3 billion after the latest round of financing, and Zhijia Technology is valued at US$1 billion. Tucson’s current market value can be regarded as the leader in the future. .

From the point of view of the track, Tucson’s future potential is indeed relatively large. According to an Essence Securities report, the traditional freight truck market in the United States is as high as 800 billion U.S. dollars, with high labor costs, accounting for 43% of operating costs per mile, and the problem of aging drivers is serious. 54% of commercial truck drivers are 45 years of age or older. There is a strong demand for autonomous driving technology.

However, in terms of specific operating conditions, US$8.49 billion may be more “paying for the future.” From the perspective of revenue, Tucson will always be at a loss from 2018 to 2020, with net losses of US$45.03 million, US$84.883 million, 177 million US dollars, a total of about 2 billion yuan. And Tucson said in the future that “a lot of expenses and continuous losses will be incurred in the foreseeable future.

From the perspective of commercialization capabilities, Tucson has not yet achieved mass production in the future. The prospectus discloses that it will cooperate with Navista and Volkswagen’s Traton for pre-installation and mass production to jointly build and deliver L4 unmanned trucks. At present, the vehicle has received 5,700 pre-orders and will be put into production in 2024 as planned .

Before mass production, the level of hardware reliability is not enough, so Tucson’s future half-car test vehicle still needs to be equipped with safety officers and drivers before it can go on the road.

Who is the second “Tucson Future”?

“Like the United States, it is difficult for the passenger car market to give birth to the next Tucson in a short period of time. The commercial sector is still the direction that domestic auto-driving related companies should pay attention to and make efforts.” Major General Ding said.

The passenger car autonomous driving market is vast. Most of the players entering the game are Internet companies with strong capital. Although there have been preliminary results, companies such as Baidu and Didi have already begun road tests, but they are still far from commercialization. The process is difficult.

From the perspective of the technical route alone, the domestic car-road coordinated route is still in the early stage of equipment laying, and it is far from reaching the level of mutual perception between cars and roads and other vehicles. Moreover, the current domestic laws on autonomous vehicles are basically in a blank state.

Foreign “smart bicycles” models are also full of difficulties. Earlier this month, the CEO of waymo, a leading autonomous driving company, resigned. According to foreign media reports, internal employees said Waymo did not have much direction inside, technology stagnated, and senior leaders set goals. unrealistic.

In contrast, self-driving commercial vehicles do not carry people, involve fewer safety issues, and the road conditions are relatively simple and fixed, and are easier to commercialize. The current domestic commercial vehicle autonomous driving fields are mainly truck freight and mines.

In the field of truck freight, Zhijia Technology and Xiaoma Zhixing have respectively completed D round financing and C+ round financing, and become unicorn companies. Among them, Zhijia Technology has introduced Guotai Junan International and Hedosophia as investors, both of which can provide Its listing assists, and according to media reports, it is in the process of SPAC merger negotiation in order to go public through backdoor. However, like Tucson’s future, both have not yet achieved mass production.

However, compared with the American truck freight market, the domestic truck freight market is not mature yet. Chen Mo, the founder of Tucson Future, once publicly mentioned the reasons for prioritizing the development of the American market.

First of all, there are only test licenses in China, and operations are not allowed. If trucks do not have an operating license, they cannot transport goods and cannot be profitable; in the United States, the cost of freight hardware is declining, and labor costs are rising, but the country has not yet reached the intersection; unmanned driving needs to be combined with drop-and-hook and box-drop transportation. Mode (after arriving at the transportation point, the tractor can drop the carriage and hang another carriage, which can shorten the stop time to a minimum), but many domestic trucks and trailers are integrated, and the drop-hang and drop-box rate not enough.

There is also great potential for autonomous driving in mines, with huge market space and high risk, difficulty in recruiting drivers, and strong demand for unmanned operations. According to Chentao Capital’s calculations, the total annual market size of domestic mine autonomous driving exceeds 100 billion.

Domestic mining autonomous driving solution providers are dominated by start-up companies, because mining operations are complex systems engineering, which not only require autonomous driving technology, but also dispatch and fleet management, and Internet of Vehicles communication technologies. Therefore, domestic large-scale equipment companies tend to cooperate in-depth with driverless start-up companies.

Tage Zhixing, a leading company in this field, was established in 2016 and has now completed 8 rounds of financing. Its founder and chief scientist Yu Guizhen stated that it is confident that it will be listed on the Science and Technology Innovation Board within 1-2 years.

However, according to Chentao Capital’s analysis, mining autonomous driving companies are still in the initial stage of commercial trial operation and field deployment testing. The work efficiency of autonomous driving has not yet been equal to that of manual driving, especially night operations have not yet carried out normal operations. Although many companies have received commercial orders, most of them are pilot projects and have not yet participated in the normal production operations of the mine.

Optimizing mass noise is a challenging problem in phono cable design. Nordost Odin 2 Tonearm Cable + solves this problem with 2 solutions. First, Nordost’s tonearm wire isolates the mass signal completely. When necessary, users can choose to mass-connect the chassis of the charcoal tray and the phono preamp to create a link with extremely low noise between the two devices. The second way, Odin 2 Tonearm Cable + uses 2 ground wire segments (detachable, equipped with 2 Dual Phono-Filament and TSC technologies) directly connected to the armor layer of the main tonearm wire, eliminating socks also interference in signal transmission. Similar to Nordost’s Supreme Reference cable line, Odin 2 Tonearm Cable + has a calculated length to minimize microphonic vibration noise. The company’s top tonearm wire uses HOLO: PLUG jacks with 4 options, straight DIN, 90-degree DIN, RCA and XLR. Odin 2 Tonearrm Cable + is manufactured by hand in the US, which is essential in making signal cables that require extreme precision. Cable Nordost Odin 2 Tonearm Cable + has a reference price of $ 12,999 / 1.2m and $ 15,999 / 2m. Nordost brand’s official distributor:

Officially launching the new Samsung AI washing machine, opening a new era of smart washing machines for the Vietnamese family. The Samsung AI washing machine will help users optimize the smart laundry experience with the most advanced technologies to analyze dirt, optimize the washing process, and remember and suggest preferred washing modes for people. use. The new Samsung AI washing machine will help save energy, time and effort so that users can spend more time on the things they love.

Continuously updated and improved, to deliver perfect cleaning results and personalize the user experience. ”

Intelligent dirt analysis, optimal clean cleaning

With different volumes and soils, even using a modern washing machine, users still have to manually adjust the amount of laundry detergent, softener and customize the mode and sub settings, or even have to pre-wash to handle stains. The new generation of Samsung AI smart washing machines analyzes the data – volume and dirt of each load, automatically optimizing the washing process and related factors for perfect clean efficiency.

AI Wash is equipped with a system of 4 sensors – analyzing the volume and dirt of clothes, thereby optimizing the amount of water, the amount of washing water and the washing time. During the washing process, the dirt sensor uses stain detection light technology; depending on the degree of soiling, the washing machine adjusts the washing time and adds less detergent; make sure the clothes are perfectly clean with no effort required.

AI Dispenser intelligent detergent compartment automatically adjusts the amount of detergent and softener by the weight sensor of the clothes; 1-fill for 1 month of use (equivalent to 16-20 washings). The laundry detergent compartment has a lid to preserve the quality of the detergent and has an easy-to-remove design for cleaning. When the detergent in the drawer has run out, the washing machine will automatically indicate a need to fill.

Personalize your user experience with a smart dashboard

According to a global survey, 7,000 washing machine users only use 3 modes on the control panel of 14-20 default washing modes. Each time, users have to turn the knob to search for the washing mode, and customize additional settings such as washing temperature, number of spin cycles, spin speed to match the type of clothes.

The new design of the Samsung washing machine’s AI Control panel is streamlined with an intuitive Vietnamese interface, using AI to remember and analyze usage habits, thereby personalizing the experience for each users and controls anytime, anywhere.

Analyze, suggest smart wash mode: The washing machine remembers and analyzes data for the last 25 washs, including date, date, time, wash mode and additional settings. Just turn the dial and wash modes are displayed according to usage history, so users will easily find their favorite washing cycle arranged at the top with additional settings without any customization required. more.

Visual display of laundry status and intelligent user guide such as automatic reminder to clean the washing bucket, notification when users use the wrong way or errors arise (if any).

Link washing-drying mode between washing machine and dryer: After washing, users just need to take the clothes from the washer through the dryer, the dryer will automatically suggest the drying mode based on the previous washing mode.

Control anytime, anywhere via SmartThings app: Samsung AI washing machine supports Internet of Things (IoT), can connect to smart devices such as smartphones, TVs, Family Hub refrigerators, and other household products. as well as devices like Alexa and Google Home. The SmartThings app not only controls the washing machine anytime, anywhere, but also recommends a wash mode by fabric type and manages the desired washing time.

-PV: BRT bus route 01 Kim Ma bus station – Yen Nghia bus station has been operating for 5 years, what is your assessment?

– Mr. Khuat Viet Hung: Up to now, I still maintain the same opinion as when the first day of operation of this “BRT bus” line was that the service on this route could not meet the basic criteria of BRT service (Passenger transport system public bus-based mass public) that must have an absolute private lane, a hard separation, roughly fenced, not creating an opportunity for other vehicles to trespass, assign different levels or priority of credit. signal at the level intersection (when the BRT bus arrives, the traffic light turns green automatically);

The stop is closed and must have convenient and safe access for passengers; connecting infrastructure and ride diagrams with regular bus routes (with the function of gathering passengers), such as taxis, motorbike taxi; Major stops also include private parking. These infrastructure requirements are not yet available in Hanoi’s “BRT No. 1” line.

Mr. Khuat Viet Hung, Vice Chairman in charge of the National Traffic Safety Committee

More importantly, the system capacity itself is too weak, the bus can accommodate 90 seats like regular buses, the peak frequency is 5 minutes / trip, while if you have reserved a separate lane, the peak hour frequency must be 1-2 minutes / trip, ensuring the service capacity from 3,000-4,500 passengers / hour / direction, confirming the higher efficiency of using the road than conventional buses and private vehicles.

Thus, the current frequency and service capacity of the current “BRT 01” line is still very far from being able to meet the requirements of a true BRT line, not to be called public passenger transport with large volume.

Thus, if compared with the above criteria, the service operating on the current “BRT 01” route in Hanoi is actually only at the level of one bus route running on a partially dedicated lane (because it is still frequent). shared by private vehicles).

-Many experts, public opinion said that “BRT 01 line is a failed test”, what is your opinion?

– When judging as success or failure, it is necessary to evaluate carefully, explicitly and fairly. If assessing the current service, it is advisable to consider only the effectiveness of a bus service with a partial priority of road use, so that the conclusions of success or failure are true and from there it can be pointed out. the real cause of the problem.

In my opinion, the first reason is the slow pace, the investment is too slow, this BRT line should have been put into operation since about 2004-2005, when there was a demand for travel, urban structure along. the route (planned to be the Nguyen Trai – Tay Son route) was suitable for a BRT line.

The current BRT bus route in Hanoi is not exactly the nature of BRT bus

However, it was not until 2017 that the service was opened and the route was adjusted to Giang Vo – Le Van Luong – To Huu. With urban density, the need to travel along the corridor in 2017 is very different, even requiring us to have urban railway.

This is a pity, if the investment was completed early in the years 2004-2005, up to now, BRT has fulfilled its mission to transition to a form of mass transit rather than road. overhead iron, urban railway. This is also a valuable lesson in transport and urban planning and implementation.

12 years behind schedule, service delivery capacity is too weak, far from meeting BRT’s basic criteria. If we had reserved a separate lane for the BRT bus, we had to provide a worthy service capacity, exploiting the full traffic capacity of the lane. At the same time, to attract passengers and create a market for the BRT, it is necessary to create favorable travel connections for passengers, keeping the right of priority for the bus when operating in the lane, when crossing intersections. …

As for now, shared infrastructure (private vehicles often violate), although there are separate lanes, types of private vehicles, other vehicles massively occupy the BRT lane, but are rarely fined, causing BRT buses ” crawling “after other types of personal vehicles during rush hour.

Besides, the station is difficult to access, the sidewalk to connect from a regular bus stop to the BRT station is encroached upon … It can be said that “BRT line 01” is like an athlete who is tied and loved. the bridge competes in the top professional competition and when he fails to win a medal, he risks being disciplined.

– So, in your opinion, how must the Hanoi transport industry deal with this BRT 01 bus route?

– It is necessary to conduct the 5-year preliminary review, point out what is the problem, must be the people who really understand, need experts who really know, enthusiastic to evaluate.

We have to accept the fact that services now need to be complete to be able to meet BRT’s criteria. Therefore, I personally would like to have a comprehensive, fair assessment, so that the service on the line is truly a BRT bus service, after 1 year, we look back and can conclude that the BRT on that line. success, or failure, as at present, the conclusion is not satisfactory.

In particular, it is necessary to clearly define “whether to prioritize the use of infrastructure for public passenger transport”, and “what is the priority, what are the priority levels”, “Type and capacity of the service is worthy of priority”.

If it is confirmed that a BRT service complete with the above mentioned criteria can help reduce traffic congestion on the route, then improve it so that it becomes complete. But if we leave it as it is now, in the psychology of the people, the functional forces and experts alike, BRT buses cause more congestion than basis.

We keep saying priority is given to public passenger transport, but the practice is very modest.

Therefore, the people, the pressing public opinion is right, because the people have not seen a true type of public transport as expected, it is the real BRT service, great service capacity, good quality, punctuality, no “crawling turtles” follow private vehicles. When public transport is given priority, whoever uses public transport will have priority, while those using private vehicles will not have priority.

-The public also said that this BRT bus route is too expensive to invest, what is your comment?

– Hanoi BRT 01 line has a total investment of about 50 million USD, this bus is expensive because we have to import all, from consultants, design, to the smallest ones to have a model. Initial picture, sometimes that is the lesson.

For now, I believe, if Hanoi wants to deploy the next BRT lines it will definitely be much cheaper. The Vietnamese have the capacity to plan, manage, design and deliver a complete BRT service at a much lower cost.

– According to the plan, Hanoi has 8 BRT fast bus routes, so how do you think it should be effectively deployed in the future?

The first thing is to turn the current BRT 01 route into a BRT fast bus as its name suggests, and then confirm whether the BRT is suitable for developing and effectively serving the travel needs of Hanoi people or not. after that, this network expansion will be considered.

Moreover, since the proposed BRT network has been put into the planning for more than a decade, there has been a huge difference in travel demand, and urban development status along the corridor has also changed. very large, even much different from the approved urban planning.

Therefore, before deciding to stop or continue with the Hanoi BRT, we need to reevaluate current practice, analyze and forecast more comprehensively to update the capital planning until 2030 and with a vision to 2050 under study and construction.
