Increasing number of passengers The US airlines lack pilots

As of: 22.06.2021 10:05 a.m.

The number of air travelers in the US is rapidly increasing again. In the meantime, the remaining pilots at some airlines are no longer sufficient to carry out all the planned flights.

The US airline Delta is looking for staff again. 1000 pilots are to be hired in the coming months. A year ago, in the middle of the corona pandemic and with constantly falling passenger numbers, the airline threatened to fire 1,700 pilots. In the end, the airline forced the unions to accept indirect wage cuts. Now Delta could even have to pay more for new employees in order to find staff again.

American Airlines is canceling flights as a precaution

American Airlines has similar problems. Especially on weekends, the number of pilots who have already been trained and tested is apparently not enough. In the event of delays and bad weather, flights are canceled because pilots would otherwise exceed their working hours and there is no one who can take over the shift. Now American canceled almost 1,000 flights for July as a precaution. The staffing level is so tight that the airline has been overwhelmed by rising demand and its own ambitious plans. The Wall Street Journal reports that there is also a frequent lack of ground crews to refuel aircraft.

Vacation trips partly at pre-crisis level

The number of vacationers in the US could return to pre-pandemic levels this month for some airlines. Delta expects the restrictions on transatlantic traffic to fall in the second half of the year. So far, travelers from Schengen countries such as Germany are still banned from entering the USA. US President Joe Biden has not yet announced that he will change anything

From April to now, Alpha has become the dominant strain in the US. Alpha’s superiority made scientists wonder why this virus strain spread so quickly. Recently, a study published online on June 7 was New York Times The quote has found the “secret of success” of this mutation: Alpha disables the first immune “stronghold” gland in the human body, giving the virus more time to multiply when it enters the body. up quickly. The Alpha mutation once made the UK crippled. Photo: Reuters. “Turn off the bell” alert Alpha has a total of 23 mutations – what sets it apart from other coronavirus strains. When this strain began to spread widely in the UK, researchers began examining the genetic sequence to look for an explanation of why it spread faster than other strains. Many researchers focused on nine mutations that change the proteins that coat the coronavirus and allow them to enter cells. One of those mutations helps the virus bind more closely to these cells, increasing the likelihood of successful infection. But other scientists focus on how Alpha affects the human immune response. Virologist Gregory Towers and colleagues at University College London cultured the coronavirus in human lung cells. They compared cells infected with Alpha with those infected with previous variants of the coronavirus. The team found that alpha-containing lung cells produced less interferon. Interferon is a protein produced naturally by cells in the immune system. They also found that in cells with Alpha, defense genes activated by interferon were less effective than in cells infected with other strains. Somehow, the most important “alarm bell” of the immune system barely “sounds” in the presence of the Alpha variant. “It becomes almost invisible (when it enters the human body),” Dr. Towers said. The UK has to impose strict restrictions because the strain B.1.1.7 spreads quickly. Photo: LBC. To find out how Alpha achieves this “invisibility,” the researchers looked at how the coronavirus replicates inside infected cells. They found that Alpha-infected cells made a lot of extra copies – about 80 times more than other variants – of a gene called Orf9b. According to previous research by molecular biologist Nevan Krogan and colleagues at the University of California, San Francisco, Orf9b makes a viral protein that attacks Tom70 — a protein needed to release interferon when the virus enters the body. body. From all of these studies, Dr. Krogan concluded that the Alpha variant contained a mutation that produced more Orf9b protein than normal. The Orf9b protein surrounds the Tom70 protein, reducing interferon production. The infected virus is no longer hindered by the immune system, so it rapidly multiplies in the human body. About 12 hours after infection, the immune system starts working again. Therefore, Dr. Towers speculates, people infected with Alpha have a stronger response than those infected with other strains. The virus-laden mucus lingers in both their oral and nasal cavities, making Alpha more contagious than ever. However, Dr. Laurent-Rolle insists more evidence is needed to support this conclusion. For example, scientists have not yet run a standard test to test the amount of the Orf9b protein. Dr. Krogan said he and his colleagues are looking to practice that experiment now. Totally different Dr. Krogan’s group also started similar tests on other strains, including the strain first identified in South Africa, called Beta (B.1.351) and the first identified strain. first in India, called Delta (B.1.617.2). The preliminary results surprised them. Both Beta and Delta reduce interferon in infected cells. But there is no indication that these two strains did so in the same way that Alpha did. Each strain evolved in a different way to control the immune system. Virus mutant particles B.1.1.7 from patient samples in the laboratory. Photo: NIAID. Cecile King, an immunologist at the Garvan Institute for Medical Research in Sydney, Australia, stressed that understanding how the virus evades the immune system will help in the development of a Covid-19 vaccine. Vaccines now help the immune system recognize mutated proteins. But research on patients recovering from Covid-19 shows that their immune systems learn to recognize viral proteins, including Orf9b. Some researchers are looking to include the coronavirus protein in a new vaccine. But this process needs care because some proteins reduce immunity. “It’s a pretty complicated process. But if we take a closer look, it might be possible,” Dr. King said.

The project’s vice president said during a conference on Wednesday (June 9) that the company is continuously developing, expanding bandwidth to serve commercial projects later this year. “We’re in talks with a number of airlines,” said Jonathan Hofeller, vice president of SpaceX. “We are developing our own airline service… we have done a number of tests so far and are looking to perfect those products to put on flights in the very near future.” SpaceX began piloting the Starlink satellite in 2018 to address the global scarcity of broadband internet connections, especially in rural areas where fiber optic connections are often unavailable. Under the trial plan, Starlink customers will pay a one-time fee of $499 for a package that includes a Wi-Fi router, self-regulating Starlink pan, and $99 per month for monthly internet services thereafter. Since its first launch, the company has launched nearly 1,800 Starlink satellites out of the 4,400 it estimates it will need for global coverage. Last year, SpaceX submitted plans to test Starlink on five Gulfstream jets. In March, SpaceX also negotiated with the FCC (Federal Communications Commission) to apply Starlink technology on all popular vehicles from trucks, marine ships to airplanes. Elon Musk made it clear on Twitter at the time: “We do not connect Tesla cars to Starlink, because our terminal is too big, This controller is only for airplanes, ships, big trucks “. Starlink’s satellites are in low Earth orbit, lower than the geostationary orbit of the larger satellites that currently provide Internet services to commercial aircraft. It is the technology that makes airlines choose to cooperate with Starlink over other competitors. However, the same technology is now being used by a range of competitors. Amazon recently announced plans for 3,000 of its own low-orbit satellites, and the UK’s OneWeb has also launched 182 of the roughly 640 planned satellites. Competitors to Starlink with plans to commercialize the aircraft are Intelsat and ViaSa, which operate satellite networks in geostationary orbit. ViaSat recently announced plans to use its next-generation satellite network on Delta’s main fleet. The California-based company is planning a low-orbit network of 300 satellites that will begin launching early next year. According to experts, Viasat will be a stiff competitor to SpaceX in the future.

A man is vaccinated with AstraZeneca in Jakarta, Indonesia, June 15. Photo: AP The results showed that only 166 cases required hospitalization. Those who received two doses of the AstraZeneca vaccine were 92% effective without requiring hospitalization, while those who received the Pfizer vaccine, the figure was 94% after dose 1 and 96% after dose 2. “These findings suggest that the level of protection of people with Delta variant from hospitalization is very high. Understanding this is important in assessing the danger that Delta variant poses to the general population.” , the study authors concluded. “The effect of not requiring hospitalization because the Delta variant after one injection of AstraZeneca is 71% and after two injections is 92%. This metric really reassures India. To choose the direction, I think we should should use modeling approaches to devise different implementation strategies and compare the impact of vaccines at each stage of the epidemic,” commented Professor of Microbiology Gagandeep Kang of India. The Delta variant first appeared in India and has been classified as a “variant of concern” by the US Centers for Disease Control and Prevention (CDC), while the World Health Organization (WHO) has called it a “variant of concern”. it is a ‘disturbing variation’. The Delta variant is expected to become a common strain in the US next fall, increasing the risk of a new wave of disease in unvaccinated people later this year.

Ekaterinburg submarine of the Russian Navy. Photo: TASS Business Insider (USA) reported that the Delta-IV class submarine Ekaterinburg has spent nearly 2 years waiting at the port in Severodvinsk. Ekaterinburg’s decommissioning also marks the “final chapter” of the Delta class that has been the mainstay of the Soviet and Russian fleets of nuclear-powered ballistic missile submarines for decades. It is expected that Delta-class submarines will be replaced by advanced Borei-class ships. Delta IV class submarines are part of a group of 43 ballistic missile nuclear submarines with the first being launched in the early 70s of the last century. There are seven Delta IV submarines in service with the Russian Navy. Among them is the Podmoskovye which in 2016 was converted into a Special Mission submarine dedicated to intelligence missions. It is known that Ekaterinburg is the second ship of the Delta-IV class to be produced, built in 1985. On August 6, 1989, during Operation Behemoth, the Ekaterinburg submarine tested 16 R-29RM Shtil ballistic missiles. while in diving mode. The first launch was successful, but a fuel leak in the rocket during the second launch halted the test. The Ekaterinburg was fortunately unharmed. Not stopping there, in 2011, a serious fire occurred on the Ekaterinburg ship. The ship then had to undergo a three-year repair process.

Gate to Dong Dau Archaeological Site (Yen Lac – Vinh Phuc). Photo: Tien Dung. Lesson 1: Used to be the largest ancient Vietnamese residence in the Northern Delta Reviewing the historical process, Yen Lac is a land rich in potential for historical relics. In Binh Dinh commune, a relic of Go Gai (also known as Dong Gai) has been found in Coc Lam village, a site of Phung Nguyen culture. In Dong Cuong commune, there is Quan Doi (also known as Quan Doi Dong) at the junior high school area, with vestiges of Phung Nguyen culture. Also in Dong Cuong commune, there is Ma Hon, in Chi Chi village, with vestiges of the Metal Age. Right in Yen Lac town, there is a famous archaeological site of Dong Dau, with vestiges of the culture of Phung Nguyen, Dong Dau, and Go Mun. Also in this area was found the site of Go Chua Bien Son with vestiges of the Phung Nguyen culture. In Nguyet Duc commune, there is Dinh Xa site, in Dinh Xa village, Dong Dau cultural site has been discovered. In this commune, there is also a site of Hai Cay bronze with traces of the Metal Age… Archaeologists have initially sketched a panorama of ancient times in this place thanks to excavations, survey and reconnaissance in Yen Lac district and Vinh Phuc province. Panorama of Dong Dau archaeological site (Yen Lac – Vinh Phuc). Photo: Tien Dung. While the district has just formed 5 industrial clusters but has not yet formed an industrial park like other areas in the province, Yen Lac advocates exploiting its strengths in culture, especially historical and cultural relics to preserve , promote, first of all to serve sustainable tourism development in order to break out of the purely agricultural district. On the basis of information provided by leaders of Yen Lac district, at the beginning of the year of Tan Suu (2021), we went to survey Dong Dau archaeological relic which was ranked as a National Historical and Cultural relic by the State. from April 21, 2000. This relic is 1.5 Km east of Yen Lac district center, completely located on a mound about 6 m high compared to the surrounding lowland field, with a total area of ​​8.5 ha, in Dong village, Yen town. Lost. Since its discovery (in 1962) until now, Dong Dau archaeological relic has been protected, serving for excavations, research, study tours of specialized scientific agencies, scientists and researchers. domestic and foreign scientists and students from local schools. Stone axes and bowls were discovered at Dong Dau archaeological site in 1999. Photo: Vinhphuc.gov.vn/ Dong Dau relic has undergone 7 major exploration and excavation times in the years: 1965-1966, 1967, 1968-1969, 1984, 1987, 1999 and 2012, with a total area of ​​758m2, concentrated on the southern slopes. East, South, West and the top of the mound with an average thickness of cultural layer over 3m (up to 6m in some places). The 7th excavation was held in December 2012 with the participation of 3 agencies, namely the Department of Archeology, Faculty of History, University of Science and Humanities – Hanoi National University, the Vietnam Archaeological Association and the Department of Archeology. Culture Sports Tourism Vinh Phuc province. Bronze artifacts discovered at Dong Dau archaeological site in 1999. Photo: Vinhphuc.gov.vn Through 7 excavations, many archaeological remains have been discovered with thousands of specimens, tons of pottery pieces of all kinds, extremely rich in materials, types, diverse in types and designs. symbols of 3 cultures: Phung Nguyen – Dong Dau – Go Mun made of stone (axe, chisels, grinding tables, rings, jewelry beads), bronze (ax, file, arrow, hook, javelin) ceramic ( pieces of pots, jars, forks, stringers, ceramic balls and many tools made of bones and horns, animal remains such as pigs, deer, deer, buffalo, cows, dogs, tigers… and quite a few fish bones. At the same time, there are also images of buffaloes, cows, chickens and many animal bones found, for the first time, burnt rice grains have been found, proving that wet rice farming has existed for a long time and plays an important role. important in the life of ancient Vietnamese residents. Dong Dau Go is a precious relic, contributing to affirming in the historical process of the nation spanning about 2 millennia, the ancient Vietnamese people stopped and settled in Dong Dau, creating the Northern Delta. and created the Red River civilization, especially built a brilliant wet rice civilization. Compared to all other archaeological sites (usually with a cultural layer of about 40-50cm), Dong Dau has the thickest cultural layer up to 6m and has a bottom-up evolution over time. Archaeologists have discovered 4 cultural layers of this archaeological site. The bottom (oldest) layer unearthed many stoneware, pottery, horn tools and many animal remains. Notably, in 1999, the Vietnam History Museum in collaboration with the Department of Culture, Sports and Tourism of Vinh Phuc conducted the 6th excavation and discovered a burial tomb, still retaining human remains of the Phung Nguyen culture. This excavation, although only 25m2, but also discovered a tomb located at a depth of 3m. Archaeologists have found very clear tomb borders. The tomb is almost intact except for the missing left femur – possibly due to later people digging a hole to hit the grave and also not ruling out the destruction of the termite nest. The reason is unknown, but found evidence that the right fibula was broken but healed. In particular, there is the custom of dyeing the teeth black and the custom of extracting the upper front teeth and the entire lower front teeth. Obviously, this is not a lost tooth, because if it falls out, the arch must leave traces of tooth points. Meanwhile, this skeleton saw that the lower arch of the jaw where it was extracted had healed to form a sharp edge. The ancient human remains found in Dong Dau were dated by radiocarbon dating (C14) method, showing that the earliest class in Dong Dau dates back to 3,500 years ago. In the remaining three cultural layers, more bronze artifacts were discovered. From the discovered archaeological relics, through the research process, up to now, it is possible to recognize the basic Dong Dau archaeological relics: Dong Dau is the largest ancient Vietnamese residence site in the center of the Northern Delta region, the largest distribution area, the thickest cultural layer, containing a huge amount of archaeological artifacts. and rich. Overview of the excavation pit at Dong Dau relic, 1969. The stages of archaeological culture following the continuous progression at the archaeological site of Dong Dau have confirmed very clearly that: The earliest class was from Phung Nguyen, followed by Dong Dau, Go Mun and finally Dong Son. And because of that, from the Dong Dau relic, Vietnamese archaeologists have a scientific basis to determine the criteria for the stages of cultural development in the Red River basin: The earliest humans present here belong to the late stage of Phung Nguyen culture, they have reached the peak of primitive stone processing techniques, polished, beautiful, sophisticated stone jewelry, began to appear. copper metallurgy. Pottery made by turntable, elegant, balanced, beautiful, typical pattern is the project of carving lines, dots, and symmetry. Wet rice farming has developed, many rice grains and rice burned in coal ash have been discovered. Next is the Dong Dau period with typical elements of reduced stone tools, thick pottery, high calcination, decorative patterns with music staff motifs, brushed into projects: letter S, number 8, symmetry ; bones, horns develop; copper casting technique became the dominant factor. The third layer belongs to the Go Mun culture period, the remaining stone items are few, the horn bones are rare, the pottery is rough, the calcination is higher than the previous two stages, mainly the broken mouth, the main decorative pattern. on the mouth. The top layer belongs to the Dong Son culture period, because the surface of the site has been plowed since it has not been discovered, but the discovered relics are scattered in the scope of the site, mainly bronze artifacts: Axes. Xeo, spear, and knife are typical of Dong Son culture. With 4 periods of archaeological culture present on the same site, the development is continuous, representing a stable and long-term settlement process of ancient Vietnamese residents to form the first State of the people. Ethnicity- State of Van Lang in the Hung King era This is the greatest value of the archaeological site of Dong Dau, not only for Vinh Phuc but also for Vietnam and Southeast Asia. These are extremely valuable evidences to learn about the customs, practices and especially the anthropological composition of the ancient Vietnamese in the Red River basin. The discovery of ancient human remains in Dong Dau will contribute to scientific documents that gradually shed light on the issue of “Vietnamese origin” that many scientists are still trying to find and research. From that, it can be affirmed that Dong Dau along with other archaeological vestiges system in Yen Lac and Vinh Phuc province is from Phung Nguyen culture to Dong Son culture, which brought the process of opening the period of Hung Vuong building the country from the mythical age of Vietnam. history but is being forgotten, wasted, not studied, preserved and promoted to serve sustainable socio-economic development.

“The new naming does not replace the scientific names of the variants, but can aid in public discussion,” said Maria Van Kerkhove, WHO technical team leader on Covid-19. Other SARS-CoV-2 variants of interest will be labeled with the words “Epsiloon”, “Zeta”, “Eta”, “Theta” and “Iota”. (Artwork: BBC) Under the new system, the British variant (B.1.1.7) is called “Alpha”, the South African variant (B.1.351) is “Beta”, the Brazilian variant (P1) is “Gamma”. The Indian variant B.1.617 is divided into sub-lineages, where the B.1.617.2 variant is called “Delta” and the B.1.617.1 variant is called “Kappa”. Names such as variant B.1.1.7.2 will continue to be used in scientific circles, because of the mutational information their names convey. “Despite their advantages, scientific names can be difficult to say and remember, and easily misinterpreted. As a result, people often refer to variants by the places where they were first discovered, causing stigma and discrimination,” according to the WHO statement. “To avoid this and simplify mass communication, WHO encourages authorities, national media and everyone else to use these new names,” the WHO said. The Greek alphabet has 24 letters and WHO has not yet planned what to do next if all 24 letters are used. According to AFP, “Epsilon”, “Zeta”, “Eta”, “Theta” and “Iota” are names for variants of interest.

WHO technical team leader on Covid-19 Maria Van Kerkhove. Photo: AFP According to the new announcement, WHO will use Greek letters to refer to variants that were first detected in countries such as the UK, South Africa and India. For example, the variant in the UK is called Alpha, in South Africa it is Beta, and in India it is Delta. The full list of names has been published on the WHO website. The Government of India earlier this month criticized the naming of variant B.1.617.2 – first detected in the country last October – as “Indian variant”, despite WHO never officially called it that. “No country should be discriminated against in detecting and reporting variants,” said WHO’s Covid-19 technical team leader Maria Van Kerkhove, “we don’t want to replace scientific names.” available, but only to assist in the transmission of certain information to the general public” If more than 24 variants are officially identified, meaning the system will run out of Greek letters, WHO will announce the new designation. Ms. Van Kerkhove on May 31 also called for close monitoring of variants and sharing of scientific data to help prevent the spread. Over the weekend, Vietnamese health officials warned of a new virus variant, which is believed to be a dangerous combination of two Alpha and Delta variants. While a scientific adviser to the British Government on May 31 said that the country is in the early stages of a third wave of Covid-19 infections, partly due to the Delta variant.

WHO Director-General Tedros Adhanom Ghebreyesus. Photo: Reuters As suggested by WHO, the COVID-19 mutation is called “British strain” or B.1.1.7 should be called “Alpha”, while the common mutant strain in South Africa is renamed “Beta” . The two Brazilian strains, called P.1 and P.2, became Gamma and Zeta, respectively, while the two subtypes of the “Indian variant”, B.1.617.1 and B.1.617.2, were called “Kappa” and “Delta”. Two other strains, first reported by the US in March of this year, were assigned the most difficult names to remember, “Epsilon” and “Iota”. Maria Van Kerkhove, head of WHO’s COVID-19 expert team, stressed that the new names will not replace the scientific name of the strain, because the scientific name is a complex combination of letters and numbers. Instead, the new name will make it easier for people to name variables in public discussions. At the same time, this will help remove the stigma against the country that first discovered the mutation. “No country should be discriminated against for detecting and reporting mutations,” and Van Kerkhove said. WHO List of VOCs of concern. List of Variants of Interest (VOI). In which, the first column is the new name proposed by WHO. The WHO’s new move comes in the context of India’s growing anger when the media calls the B.1.617 virus strain an “Indian variant”. India’s Health Ministry argued last month that the name freely used in the media was “misleading” because it was not a name designated by the WHO. Earlier, in February, Professor Salim Abdool Karim, then co-chair of South Africa’s Ministerial Advisory Committee on COVID-19, told CNN in an interview to stop calling the virus spreading. in his country is the “South African variant.” Instead, call it by its scientific name: 501Y.V2. The politically correct idea of ​​WHO is supported by many countries. But it also confuses many people. Some observers argue that Greek letters are actually not that easy to remember. While others point out that the WHO is in danger of “running out of names” at some point, since the Greek alphabet has only 24 letters.

When having a good soil environment for plants, plant care is also very important, mainly fertilizing and pruning. Fertilization, it is necessary to follow the rhythm of the tree’s life. For example, a newly planted tree, its life cycle is the bursts of buds (buds). As for fruit trees, the tree’s life rhythm is: harvesting, creating buds, flowering and raising fruit. The following is the plant care process Dr. Tran Kim Tinh, lecturer at the Faculty of Agriculture and Applied Biology – Can Tho University, introduces it to readers for reference. Plant ground cover grass. Photo: Minh Dam. First, plant ground cover grass. Keep the water in the ditch 50-60 cm above the ground. Sprinkler irrigation (small rays) or permeable irrigation. Post-harvest pruning of fruit trees. The tree is still small, after each bud, needs to be pruned, created a canopy and only produces 3-4 buds in a year. In terms of fertilizer use, organic fertilizers must be applied annually and only when needed to produce sprouts for seedlings. For fruit trees, fertilize when creating buds to use high nitrogen. When the tree is in the stage of growing young fruit, it reduces nitrogen and increases potassium. As fruit trees grow, farmers should further reduce nitrogen and increase potassium. Farmers should fertilize plants with organic fertilizer every year. (In the photo: Compost production at Clean Farm Company). Photo: Minh Dam. Common mistakes in farming Currently, on land crops, there are too many errors in soil preparation for planting and crop care. The prerequisite is to have the right soil physical environment for plant roots to develop. A lot of gardens, the preparation and management of the land is not right. Errors such as soil compaction are very common in all provinces. This leads to vegetable plants not growing evenly, corn not developing roots, orange orchards yellowing leaves, sleeping during the day. The structure of the soil (clump of soil) is not suitable, the lump of soil is too big for the roots to develop. Soil is compacted, reducing permeability. Keep water too high in the orchard. Use soil that is too acidic to grow fruit trees. Converting rice land to grow fruit trees, but there is no way to prepare the land properly. Improper watering. Planting trees buried roots too deep. Too much nitrogen fertilizer and foliar spray have too many growth stimulants, making the canopy unbalanced with the roots, the tree sleeps during the day. The soil structure must be suitable for the plant. Photo: Minh Dam. In farming there are mistakes, which can be easily remedied. For example, over-fertilizing nitrogen, spraying foliar fertilizers, but there are many errors in cultivation, which are difficult to overcome or even impossible to overcome, but must be cut down to replant. For example, in rice farming, farmers are advised to withdraw water mid-season, or to withdraw water several times in a crop. If farmers withdraw water by draining water from the field, this is a very dangerous practice. Because of doing so, the rice soil becomes acidic very quickly. Instead of recommending water withdrawal, it must be recommended to squeeze the water. That means adjusting the amount of watering so that by that point the field becomes dry. For upland crops, soil compaction is very dangerous, because when the soil is compacted, it is very difficult to overcome. The pH must be right One thing to be concerned about, the soil pH in the Mekong Delta is now seriously declining and depleted of potassium. Plants cannot absorb nutrients effectively when the pH is not raised to 6-6.5. Due to the serious decrease in organic matter in rice soil, when flooded, it is not possible to raise the pH. There are still many shortcomings in rice cultivation, when it comes to soil, that need to be studied. Soils in the Mekong Delta are seriously lacking in potassium and need to be supplemented with potassium, especially in the fruiting stage. Photo: Minh Dam. It is not enough, soil pH must be suitable and nutrients for plants must be sufficient in quantity and type. It has been shown in science that the mineral nutrients for plants must be sufficient in type (14 types) and in quantity, if one of the 14 types is lacking, the crop yield will decrease, even though 13 types The rest are high. In order for plants to absorb nutrients well, the pH of the soil must be suitable, preferably 6-6.5. Below pH 6, absorption of some nutrients is difficult and when the pH drops to 4-5, nutrient absorption is severely reduced. No plants grow normally under low pH and high pH conditions. For example, the pineapple tree can grow on acidic soil, but it is not normal. For sustainable farming, the following criteria should be considered and trained for farmers: Technical level of farmers, organic content in soil, soil pH in profile, soil texture, soil structure in analysis. area, irrigation capacity, drainage, fertilizer application process. Currently, there are still many issues that need to be studied to determine the soil properties that need to be addressed. The ecological characteristics need to be analyzed thoroughly, for ecological zoning. Minh Dam – Ngoc Thang ( write the)

Activities to explore the nature of Cam mountain attract many young people. Cloud hunting camping Cam Mountain, also known as Thien Cam Son, belongs to An Giang province. This is the highest mountain in the Mekong Delta, and is considered the “Da Lat of the West” because of its cool and fresh air. Currently, visitors can participate in camping and rattan hunting activities at Nha Cua May homestay located on Cam mountain. Up to the present time, this is the only place for tourists to stay overnight and experience the life of the people of An Giang mountainous area. Duong Thi Cam Van was born and raised in That Son area, she has a great love for the natural beauty here. Pioneering in camping activities on Cam mountain, Van shared with Zing: “In the past, the mountain mainly developed spiritual tourism, visitors came to the temple and then returned, few people stayed. I want to introduce visitors to other beauties of the mountain, which people may not know yet.” Homestay is built in the middle of the mountain. From a small hut with the original purpose of keeping the garden, Van and his family converted into a house with bamboo and leaves to rest. With the support of friends, Van develops homestay service and welcomes guests to the house to play, enjoy the fresh mountain air. “I think where I live the weather is very cool, the scenery is also beautiful, why not create a resort for everyone,” Van said. Guests coming to the homestay will have the opportunity to experience camping and cloud hunting activities, in addition to enjoying the rustic dishes of the An Giang mountains. Huynh Ly (HCMC) shared: “I found out about Nha by chance through a tour group. At first, I didn’t think the West would have a mountain camping area like this. Very impressive experience. Everything is simple, nestled in the middle of the mountains and forests, opening the door in the morning, the clouds flood into the room. Every moment of the day is a completely different scene.” According to Ly, the most memorable memory of riding a motorbike taxi from the foot of the mountain to the house is a little adventurous, a little refreshing, watching the wild landscape of the mountains in the cool breeze. The peaceful space in the mountains helps visitors forget the stress in life. Discover the nature of Cam mountain In addition to camping activities, hunting clouds, enjoying local dishes, Van also regularly organizes picnics, helping visitors to clearly feel the fresh beauty of the Cam Mountain. “The rainy season is the most beautiful season of Cam Mountain, because in this season the waterfalls and streams are very beautiful. The feeling of immersing in the early morning mist, standing on a high hill listening to birds singing, watching majestic waterfalls, I really want to share with everyone,” Van said. Visitors also have the opportunity to experience mountain crab fishing, visit strawberry, durian and avocado gardens and understand more about the history of the land.

Illustration. Referring to Nam Dinh without mentioning banh xiu pao is indeed a huge omission. It is known that banh xiao originated from the Chinese people. Xiu Pao is a cake with a thin crust like a baked mooncake, but softer and more fragrant. The filling includes char siu meat, eggs, flour, a little bit of pork fat and some typical spices of Nam Dinh people. From the outside of this cake, you might mistake it for a fried dumpling, but it’s not. After being fried in hot oil, each piece of hot banh xiao is crispy in the mouth, the aroma of the cake mixed with the aroma of meat makes it difficult for visitors to resist. Nam Dinh beef noodle soup Nam Dinh beef noodle soup has become a famous brand throughout the country, wherever one goes, one can see a pho restaurant with the famous Nam Dinh beef noodle brand. If Hanoi beef noodle soup is attractive because of the full look of ingredients, Nam Dinh beef noodle soup is attractive by the way it is processed with pho broth and beef. Talking about the heirloom recipe for Nam Dinh beef noodle soup, there is no universal recipe, because beef noodle soup here is cooked according to each family’s own recipe but is very attractive to visitors, “easy to get addicted to”. “. In most of Nam Dinh, people make pho and pho broth according to the traditional recipe, the noodles are soft, the pho broth is sweet and bone-flavored, and each piece of beef is fresh and not chewy. All blend together to form an extremely attractive and wonderful traditional pho flavor. Nam Dinh beef noodle soup makes visitors want to eat again but do not want to return. Little sticky rice Come to Nam Dinh, definitely enjoy a bowl of sticky rice at Hang Sat, this place is known as the best sticky rice restaurant in Nam Dinh. Sticky rice consists of white sticky rice served with char siu meat. The sticky rice here is extremely delicious with fluffy, bouncy sticky rice seeds, the meat is braised soft to melting plus the gravy is extremely rich. The fragrant plasticity of glutinous rice, the sweet flesh of sausages and char siu meat plus the spicy and rich taste of the sauce will make diners almost want to rub the delicious taste. Candy Doi It seems that candies are sold all over the North, but few people know that this snack originated from Nam Dinh. People call this candied sausage probably because its appearance is easily associated with the dish that the North people love so much. The ingredients to make this candy include: peanuts, sugar, malt, vanilla, but to make delicious sausage is not a simple thing. All thanks to the ingenuity and meticulousness of the candy maker. Longan Cake Longan cake is also one of the famous specialties of Nam Dinh that people often bring back as gifts. Hearing the name Banh Long, many people will think that this is a cake made from longan or longan fruit, but Longan cake is made from the famous yellow-flowered female rice of Nam Dinh. It looks easy to make, but in reality, making a delicious batch of cakes takes a lot of effort. From glutinous rice, chicken eggs, sugar and pork fat, through the skillful hands of the processor, round cakes, small and beautiful, like longan and golden in color.

In addition, in order to optimize the layout of scientific research, face the front line of technology and the market, explore the establishment of new R&D institutions, in terms of systematically promoting innovation, in order to implement the national innovation-driven development strategy, China Mobile has deployed scientific and technological innovation R&D carriers in the Yangtze River Delta region and integrated into the national New District-Nanjing Jiangbei New District master plan, the establishment of China Mobile Yangtze River Delta (Nanjing) Science and Technology Innovation Center, China Mobile Zijin (Jiangsu) Innovation Research Institute, together with Southeast University, Zijinshan Laboratory and other key universities and research institutes, fully integrate Jiangsu The provincial scientific and technological innovation resource advantage, organize and promote the Internet of Things, cloud computing, big data, blockchain and other technology research and product application development, and accelerate the cultivation of core competitiveness.

In order to actively respond to the national strategy, in Jiangsu, China Mobile established the Yangtze River Delta 5G Innovation Development Industry Alliance, China Mobile Yangtze River Delta (Nanjing) Science and Technology Innovation Center, China Mobile Zijin (Jiangsu) Innovation Research Institute, and reached a strategic cooperation with Southeast University. Co-build joint innovation centers, joint laboratories, etc., to build agile and accessible network facilities for the Yangtze River Delta. Recently, during the “Mobile Strong Innovation 5G Helps Growth” Jiangsu Regional Tour, the reporter walked into the Jiangsu Mobile Network Management Center and the China Mobile 5G Joint Innovation Center at Southeast University for a physical visit experience and felt that Jiangsu Mobile is a 5G network in the Yangtze River Delta Efforts made by construction. Improve 5G network application experience in many ways It is reported that Jiangsu Mobile took the lead and successfully explored the 5G C-RAN networking experience, which was eventually replicated across the country. At present, Jiangsu Mobile has the highest proportion of C-RAN in the country and is highly representative. “5G C-RAN networking can save rent by saving 20% ​​of building 5-band and 4-baseband boards to reduce the number of computer rooms. C-RAN accounts for more than 90% and saves more than 700 million yuan in investment.” The on-site staff said. Not only that, Jiangsu Mobile is also researching low-cost solutions to help the development of 5G vertical industries, and building a wireless cloud small station test network with Zijinshan Laboratory, China Mobile Research Institute, and China Mobile Design Institute, smart-simplified offloading, and base stations with lightweight edge computing Ability to help ToB industry private network price reduction and rapid deployment. It is understood that the Jiangsu company of this project opened the world’s first 2.6GHz 5G O-RAN SA independent networking base station as early as November 2019. A lot of work has been done in the standardization of relevant requirements for wireless cloud small stations and the performance testing of existing networks. It has also formed a joint research team with relevant R&D units, which has achieved initial results. In terms of network application, the “5G+AI Quality Inspection Demonstration Workshop” jointly created by Changzhou Mobile and Jingyan Technology is the first billion-dollar 5G+ smart factory project in Jiangsu Province. 5G+MEC private network is deployed in Jingyan Technology’s production workshop. The 5G+AI quality inspection method transforms the original manual quality inspection into machine quality inspection, realizes the digital upgrade of the industry, saves production costs, and improves the production efficiency of enterprises. The reporter learned that Jingyan Technology mainly provides high-complexity core components for the 3C electronics and automotive fields. As a labor-intensive enterprise, before the introduction of AI quality inspection, nearly 60% of Jingyan Technology’s manpower was used for product quality inspection. , For a long time, there have been difficulties such as high job mobility and low work efficiency of quality inspection workers. Now, the multi-angle high-speed camera on the AI ​​quality inspection equipment can continuously take high-definition pictures of products, and pass them back to the cloud through the mobile 5G private network for AI recognition, and a precision product can be completed in 1-2 seconds. Defect detection. In addition, the 5G+AI quality inspection has greatly reduced the detection error rate caused by manual quality inspection, and has also played a positive role in improving the production efficiency of the enterprise. “Through nearly a year of construction and deployment, there are now 22 quality inspection machines in the Jingyan technology workshop, and the workload is equivalent to nearly 300 quality inspection workers. According to the average cost of 100,000 yuan per person per year, nearly 30 million yuan has been saved. Labor cost.” Pan Zhengyi, CEO of Changzhou Weiyi Intelligent Manufacturing Technology Co., Ltd., who participated in this project, introduced. At the same time, Changzhou Mobile also cooperated with the Zhonglou District Government of Changzhou City and Changzhou Weiyi Intelligent Manufacturing Technology Co., Ltd. to create a 5G industrial big data cloud platform, which will analyze the quality inspection data of Jingyan Technology for big data, calculate the product test results, and combine them simultaneously. Intensify the production process, guide and optimize the production plan, empower the production efficiency of the enterprise, and reduce the loss. In addition, due to Jingyan Technology’s higher requirements for 5G network uplink bandwidth, Changzhou Mobile Innovation piloted 4.9G 3U1D large uplink technology in Jingyan Technology Workshop. After successful application, the peak uplink rate reached 700Mbps, and the average uplink rate was about 560Mbps. At present, Changzhou Mobile is deploying 2.6G+4.9G uplink CA at Jingyan Technology to further increase the bandwidth requirements of industry applications. In addition, Changzhou Mobile has effectively reduced the end-to-end delay of Jingyan Technology’s 5G network by applying new technologies such as uplink pre-scheduling, SA DRX, and SR scheduling. In terms of resource scheduling, Changzhou Mobile is deploying 2.6G+4.9G uplink CA at Jingyan Technology. The resource allocation mode can be flexibly selected according to the actual needs of the workshop site, and the resource allocation ratio can be set, and different scheduling priorities can be set to the corresponding slice +5QI. This will further improve the download rate and user experience of Jingyan technology private network users. It is worth mentioning that in terms of energy conservation, Jiangsu Mobile responded to the national “carbon neutral” initiative and took the lead in energy-saving research and development, building a “green network”, and co-developing a network-level smart energy-saving platform with the research institute. The current energy-saving level is at Leading the country, and has formed the first case of large-scale cell access in China. Join hands with Southeast University to strengthen network technology innovation On January 19th, China Mobile Communications Group Co., Ltd. and Southeast University held a strategic cooperation agreement signing ceremony in Nanjing. The two parties will give full play to their respective technological advantages, talent advantages, and resource advantages, and carry out extensive cooperation on technological innovation and talent training. , To jointly create a new model of industry-university cooperation. In this event, we also learned that the two sides have achieved good results in research on ultra-large-scale antennas, D-MIMO, and millimeter waves for 6G and Dongda. As we all know, commercial 5G indoor sub-systems increase capacity by densely deploying low-power multi-antenna small stations. However, due to the problem of multi-cell interference, it is difficult to further increase the capacity with the traditional cell splitting and co-cell implementation methods. On the infrastructure of the existing commercial indoor distribution system, multiple small stations are coordinated to form a large-scale distributed MIMO, which can not only avoid interference, but also significantly increase the system capacity. According to Wang Dongming, professor of Southeast University and deputy head of the expert group of the 6G Technology Promotion Group of the Ministry of Industry and Information Technology, currently, the 5G-863 major project led by the State Key Laboratory of Mobile Communications of Southeast University has constructed the industry’s largest 128-antenna large-scale distributed MIMO test System, third-party test results show that the spectrum efficiency can reach 100bit/s/Hz. “At present, Southeast University and Jiangsu Mobile have cooperated and explored a complete solution for commercial indoor distribution systems to achieve distributed cooperative MIMO based on the wireless cloud network architecture, and have carried out experimental verification. On the basis of large-scale distributed MIMO, it has broken the traditional cellular Architecture and cell splitting thinking, using distributed and scalable collaborative transmission algorithms to form a cellular-free wireless access network, has been proven to further improve the spectrum efficiency of wireless communication systems, and is also regarded as a key to 6G Technology.” Wang Dongming said. In addition, Professor Wang Wenjin from the State Key Laboratory of Mobile Communications of Southeast University pointed out: “Compared with the existing 5G massive MIMO technology, the ultra-massive MIMO technology further increases the base station side antenna elements and radio frequency channels to deeply tap the potential of the wireless communication space dimension. Significantly improve spectrum efficiency and power efficiency.” In order to explore and analyze the characteristics of ultra-large-scale MIMO channels, and verify the key transmission technologies of ultra-large-scale MIMO in typical actual scenarios, leading the original innovation of key technologies in this field, the Key Laboratory of Mobile Communications of Southeast University takes the lead, and Jiangsu Mobile cooperates with joint explorations. Nanjing Jiangning Wireless Valley has constructed the world’s largest ultra-large-scale MIMO field experiment system. “The experimental system is driven by 128 radio frequency channels with 1024 antenna elements, and the horizontal array width is up to 7 meters in a typical frequency band. This experimental system will help my country’s B5G backward evolution of the ultra-large-scale MIMO technology pre-research and maintain my country’s mobile communications First-mover advantage in technology.” Talking about the next plan, the two parties stated that in the next step, China Mobile and Southeast University will jointly build a “joint innovation center”, “new network networking technology joint laboratory”, and “future medical and health technology joint laboratory” to create multi-field scientific research. The cooperation platform adds luster to the innovation of network construction in the Yangtze River Delta region.

Qiandao Lake, also known as Xin’anjiang Reservoir, is an artificial lake formed after the dam closure. The lake area reaches 573 square kilometers and the reservoir capacity is 17.84 billion cubic meters, which is equivalent to the capacity of 3184 West Lakes. It is the largest artificial lake in my country. Qiandao Lake is one of the first national-level scenic spots in my country. It is a dazzling emerald on the golden tourist route of “Hangzhou DD Qiandao Lake DD Huangshan”, a famous mountain and water city. The clear water in the scenic area is peculiar, thousands of islands are beautiful, the natural scenery is exquisite, the ecological environment is excellent, and it has the reputation of “the middle reaches of the Qiandao clear water painting”. Its main characteristic landscape is the so-called Thousand Islands, Xiushui, and Golden Belt. Thousand Island Lake, the island is as its name, because there are more than a thousand islands of different shapes in the lake, so it gets its name. These islands have their own characteristics and are green and dripping, and they are hidden from the green mountains and clear waters. From a distance, if it were not for the area where the island and the lake are surrounded by a layer of golden soil (“golden belt”), it is really hard to tell. Where is the mountain, where is the water. The island has a quiet environment, excellent ecology and rich historical sites. There are “flower islands” with laurel fragrance and red plum clusters, “animal islands” filled with monkeys and poisonous snakes, as well as strange stone islands lined with strange rocks, and many It is the “historical island” left by the ruins and so on. Of course, the most worth seeing is Meifeng Island, a first-class scenic spot in Qiandao Lake, because it has the highest altitude and is the best place to ascend the scenic spot to view the lake. It can have a sweeping view of the beauty of Qiandao Lake. As for the water of Qiandao Lake, let alone how clear it is, although it is 100 meters deep, it has a visibility of up to 12 meters. Nearly 600 square kilometers of the open lake, the blue sky and white clouds, surrounding mountains, lush green forests and other scenery are all clearly reflected in the water. Boating on the lake can experience the artistic conception of “boat walking in the scene and people swimming in the painting”. People can’t help but think of a poem by Shen Yue in the Southern Dynasties praising his clear water: “Dong Che follows the clear and light, and there is no winter and spring in the bright mirror; Qianren writes the tree, and sees the scales in a hundred zhang.” Moreover, the water quality of Qiandao Lake is pure and sweet, reaching the national Class I water quality standard. According to China’s largest rivers and lakes, it not only benefits the thousands of households in Hangzhou, but also the Nongfu Spring, which we often drink, is water taken from the depths of Qiandao Lake. . He was praised as “the best beautiful water in the world” by Mu Qing, former president of Xinhua News Agency. However, behind the magnificent scenery of lakes and mountains, it is of course inseparable from the dedication and love of people. Looking at the vast expanse of blue waves in front of him, who would have thought that there are still two thousand-year-old cities hidden underneath, and a period of poignant homesickness. In 1959, in order to cooperate with China’s first five-year plan, China’s first self-designed and constructed large-scale water conservancy hydropower station was built at Tongguan Koukou of Xin’an River, and the reservoir formed by interception and impoundment will be built in Han and Tang Dynasties. The two thousand-year-old cities of “Lion City and He City” during the year, together with many surrounding towns and 10,000 acres of fertile land, were all submerged under Qiandao Lake. Nearly 300,000 people have left their hometowns and emigrated, showing that the lake’s beautiful waters are full of ancestors. We miss our hometown. For the beautiful lake in front of us, the people of Qiandao Lake today are doing all they can to care for them. They insist on closing mountains for reforestation, shutting down polluting companies, cleaning the lake regularly, etc. I believe it is also the care of the people of Qiandao Lake. Good for all the world!

According to the National Center for Socio-Economic Information and Forecasting (Ministry of Planning and Investment), the Mekong Delta is the largest agricultural production region of our country, playing an important role in the national economy, especially is in ensuring national food security. However, the Mekong Delta is a coastal lowland area, so every year, the sea water intrudes deeply into the mainland. Saline intrusion is a big challenge in the Mekong Delta. Photo: VGP This phenomenon appears cyclical and usually occurs sharply in the dry season months, from November to May every year. Saline intrusion is often affected by a number of factors such as flow from upstream to the Mekong Delta; flows in rivers, canals in interior fields; the tidal regime in the Mekong Delta; climate change, human impacts in water exploitation and use. In the past 6 years, the Mekong Delta has experienced two record saline intrusion waves, with intense and fierce intensity in 2015/2016 and 2019/2020, leading to a shortage of fresh water. wide, seriously affecting production and people’s daily life … In the dry season 2020/2021, saline intrusion in the Mekong Delta is higher than the average for many years, but not as serious as the dry season in 2019/2020, but the situation is also quite complicated. Up to the end of February 2021, in the Mekong Delta, there appeared 3 times of high saline intrusion, the salinity boundary 4g / l in Vam Co Dong river and Vam Co Tay river is 30-32km lower than the same period in 2020; the 4g / l salinity boundary in the estuaries of the Mekong River is 5-25km lower than that of the same period in 2020; The salinity boundary of 4g / l on Cai Lon river is 10-13km lower than that of the same period in 2020. Salty drought has damaged many areas of rice, fruit trees, aquaculture and vegetables, both agricultural production activities and daily life of the people are negatively affected. Saline intrusion combined with water shortage due to the effects of the saline drought season in 2019/2020 makes the total flow to be less than the average for many years and agricultural production is seriously affected. An estimated 40,000 ha of fruit trees (Tien Giang 19,000 ha, Ben Tre 15,000 ha, Vinh Long 1,800 ha, Soc Trang 3,400 ha) and about 5,000 ha of rice in Tra Vinh province have a shortage of irrigation water. With people’s lives, drought also makes many households seriously lack of water for daily use, even water supplied from clean water plants in urban areas in many provinces also shows signs of salinity. The main cause of saline intrusion in the Mekong Delta in 2020/2021 is attributed to the lack of rainfall, water resources in the upper Mekong River upstream during the 2020 flood season, and the 2020 flood peak at the upstream of the Mekong River on the Tien River. , the Hau river (An Giang province) is at a low level (below alert 1), leading to a shortage of flow in the dry season 2020-2021 from the upper Mekong river delta to the Mekong Delta by 10-20% compared to the average of many years. In addition, the total flow from the upper Mekong River (at Kratie station, Cambodia) to the Mekong Delta is in shortage compared to the average of many years about 5-15%. Solutions to ensure water security According to the National Center for Socio-Economic Forecasting and Information (NCIF), in the coming time, it is necessary to always be prepared with situational solutions to help people cope with urgent drought such as plan to mobilize mobile tank trucks to carry fresh water for households living in scattered, remote, coastal and island areas. Along with that, deploying drilling wells to supplement fresh water sources, extending pipes from concentrated water plants in the freshwater area to supply affected residential areas, installing additional public taps to supply households affected by saline intrusion use. Review, upgrade, expand and extend the pipeline with neighboring works with excess capacity to supply clean water to the people in the affected area. Regularly observe the water level of the reservoir, check the used capacity and the remaining capacity in the reservoir for treatment solutions to adjust irrigation water to suit production reality. Concentrate on investigating and searching underground water sources, especially deep aquifers to serve water supply for daily life in areas frequently subjected to saline water intrusion. Installation of salt water and brackish water filtration systems (RO equipment) in rural centralized domestic water supply schemes that are frequently affected by saline intrusion. To build freshwater reservoirs in dead-end canals and old diversion dams, and temporary dams to prevent salinity to keep fresh water sources for concentrated rural water supply stations. Investing in the construction of closed irrigation systems, implementing projects on dykes, embankments, key irrigation dams to prevent salinity, fresh storage for production and people’s livelihood. Saline intrusion negatively affects agriculture. The next solution is to regularly dredge the inland canals, clear and clear the flow for all canals, repair damaged works, carry out maintenance and repair of machines and equipment. operation, backup pumps to ensure proactive in regulating for irrigation and water pumping when saline drought, efficient operation of freshwater reservoirs. NCIF also believes that it is necessary to promote cooperation in the Mekong-Lan Thuong cooperation mechanism (MLC) on water exploitation and use. The decline in flow in the upper Mekong River leads to drought and saltwater intrusion in the Mekong Delta, so the water resource management in the Mekong Delta must be associated with the problems of water exploitation and use of 6 a country that shares the Mekong River. Accordingly, it is necessary to promote negotiations so that countries with large hydropower reservoirs, including in the main and tributaries, cooperate in the operation of power generation, water discharge downstream, ensuring flow maintenance. minimum level on the river. In addition, it is necessary to strengthen cooperation with countries experienced in responding to climate change, sea level rise, saltwater intrusion and drought such as the Netherlands, Israel, and Australia to enlist the help of countries and international organizations in coping with drought in particular and climate change in general It is necessary to widely propagate and guide people to implement measures to use water in an economical and efficient manner, especially in irrigation and daily life, to combat wasteful water sources. Encourage people to be proactive in case of water shortage with water storage solutions.

This is the first data center in Vietnam that meets Uptime Tier 3 standards in both design (TCCD) and construction and operation (TCCF).

Uptime Tier 3 is the 3rd on the Uptime Institute’s four-tiered data center scale.

To achieve this standard, a Data Center system must ensure uptime (uptime) of 99.982% or more and downtime (downtime) not more than 1.6 hours per year.

In addition, this system must be capable of redundancy to still be able to operate if the power is lost for up to 72 consecutive hours.

To meet the strict standards of Uptime Institute, ecoDC uses 100% of infrastructure equipment from two strategic partners, Delta and Arista.

Besides, this Data Center also uses an inrow cooling system. This is an energy saving technology for the first time deployed in Vietnam with the ability to control the cooling temperature to each server.

This system includes air conditioning running along the rack with hot air intake assist. Thanks to that, ecoDC can increase cooling efficiency and reduce power consumption.

Vietnam currently has a total of 5 Data Center systems meeting Uptime Tier 3 standards. However, these systems only meet Uptime Tier 3 standard in terms of design.

This data center costs the developer about 100 billion VND. Currently, the system has been completed with 6 PODs (box-type data centers) with a total of 150 racks (network cabinets). EcoDC will officially launch and start operating from April 2021.

Sharing at this event, Deputy Minister of Information and Communications Nguyen Huy Dung said that the ecoDC data center meeting both Uptime Tier 3 standards in design and operation is a serious work result of HTC-ITC. This will also be a solid step in the process of transforming the number of countries.

According to Deputy Minister Nguyen Huy Dung, in order to have a lasting and strong development, enterprises must associate their mission with the national one.

Vietnam is implementing digital transformation, moving all activities from real space to cyberspace, from real to digital environment.

In the National Digital Transformation program, the Ministry of Information and Communications determined that Vietnam must develop digital infrastructure, including broadband telecommunications infrastructure, cloud computing, electronic identification and authentication. Vietnam is also realizing the vision that each citizen has a smartphone, each household has an Internet fiber optic cable connection.

The most fundamental difference between telecom and digital infrastructure is data centers and cloud computing platforms that make IT a service accessible to everyone.

In that process, businesses need to receive the mission that is in sync with the country’s mission.

Deputy Minister Nguyen Huy Dung suggested, as an enterprise providing basic infrastructure, HTC-ITC should soon work with functional units of the Ministry of Information and Communications to meet the technical requirements set forth for the ensure network operation and safety.

As a platform provider, HTC-ITC assumes the mission of being a “giant shoulder” for small and medium enterprises and for the Vietnamese digital transformation process.

Located about 80 km from Hanoi, Van Long is the largest wetland nature reserve in the Northern Delta, located in Gia Vien district, Ninh Binh province.
