China, these two words must be the “nail in the eye” of many countries.

70 years ago, China was poor and weak, but now it is the second most powerful country in the world. Over time, it will not be difficult to surpass the United States.

In just 70 years, great changes have taken place in China. It can be said that the sun and the moon are changing for a new day!

Although China is still in a developing country, with the development of science and technology, China’s scientific and technological strength is already ahead of most countries. Today I want to tell you that a technology in China has been ahead of the world for 20 years.

It is my country’s desertification control technology.

The desertification in western China is widespread, and it is also one of the most severely affected countries in the world. Of course, the government and people of our country must not wait to die. They wanted to do something, so they started desertification control.

A series of engineering measures and biological measures, such as building water conservancy projects, building shelter forests, water transfer projects, returning farmland to forests and grasslands, are all aimed at combating desertification.

I don’t need to say more about the benefits of desert control. If we can control the desertification of the land well, it will definitely enable us to have a better living environment.

In recent years, the global green area has gradually become larger, and data shows that a quarter of the area comes from China. This is China’s power and Chinese wisdom.

The control of desertification not only solves ecological problems, but also drives people in poverty-stricken areas out of poverty. The transformation of ecology also further reduces natural disasters in desert areas.

Every country has desert areas, but why is China’s technology so far ahead?

This is due to the hard research and practice of Chinese scientists and the great attention of the people’s government. Science and technology are important, but leaders are even more important.

They play a leading role, leading the people to work tirelessly for the prosperity and strength of the motherland.

Desertification technology not only reflects the wisdom of the Chinese people, but also reflects that China is a far-sighted country.

We have always adhered to the concept of symbiosis between man and nature. We rely on nature, so we must protect the natural ecology.

Therefore, it is understandable that the desertification technology is far ahead.

The 2021 Award evaluation process is carried out according to regulations, including checking application conditions; consult experts to review; evaluated at the Foundation’s Scientific Council (OSC) and the Award Council. On April 29, 2021, the Prize Council for 2021 met to evaluate and select applications. However, after more than 4 hours of discussion and voting, the Award Council decided not to recommend awarding the nominations. On May 13, 2021, the Minister of Science and Technology approved this proposal. Too few good records? Professor Ngo Viet Trung, Chairman of the Award Council, said that this year, although the number of applications for evaluation and selection was similar to previous years, after the initial review, there were only 2 scientific activities in Earth Science and Science. Environmental and Agricultural Biology nominate 2 entries for the Main Prize and 2 for the Junior Award for consideration at the Awards Panel. This year’s nominations are all in the experimental field, related to issues of concern to scientists around the world. It is the work of Assoc.Prof.Dr. Ngo Duc Thanh, Dr. Bui Minh Tuan on climate change in rain, and the work on the use of antibiotic substitutes in aquaculture by Dr. Do Huu Hoang, a project on the technical system of growing chrysanthemums on a large scale by Dr. Hoang Thanh Tung. Will young scientists have more opportunities at the Ta Quang Buu Prize? Prof. Nguyen Huu Duc, Chairman of the Physics Council, said that although this year the Science Council also received a number of applications, including works published in journals with IF coefficients, but did not nominate any works. to the Awards Committee. Explaining this, Prof. Duc said the reason is that most of these works have only been published about half a year ago, while the Physics Council thinks that it is necessary to evaluate the works at an international level, through by number of citations. “So the Physics committee members agreed to give it another year to have a more accurate assessment of the publication quality with these works.” In the Science Council in Mathematics, there are also two nominations that, according to Prof. Ngo Viet Trung, are of sufficient quality. However, at the time of voting, both of these applications did not receive 2/3 of the votes to be nominated to the Award Council. This may have caused a negative resonance if people did not understand the situation of this year “- Professor Trung shared. “However, I confirm that no works have been awarded the award that does not fully reflect the development reality of the country’s science and technology.” According to Professor Ngo Viet Trung, looking at the quality of international publication of basic science today, the number of articles in leading journals has increased markedly and the quality is much better than the time when there was a Ta Quang Buu Award. “However, each year the quantity and quality of applications for awarding the Prize depends on many other factors such as the self-nomination of scientists or the nomination of research and training organizations. create. Scientists are afraid to nominate themselves for the prize, while many agencies are not interested in nominating outstanding works. In addition, awarding a prize to an individual or to a work also limits nominations because scientific achievements are often confirmed through a cluster of works and through the cooperation of many scientists. Professor Ngo Viet Trung also said that it is important that the quality of the award is guaranteed. “It’s normal for an award not to be given by anyone. The Board of Directors has worked very seriously, not for the sake of having a prize but trying to award it, which will affect the prestige of the award. For example, China’s highest national award for science and technology (worth about $750,000) has gone without a prize twice, Mr. Trung cited. In particular, in 2015, there was no award, but China had a Nobel Prize in Medicine right before the national award. Young scientists need to be taken care of The 2021 season has passed, but according to Prof. Ngo Viet Trung, there are contents that the Foundation needs to discuss to draw lessons for the following years, so that the award can achieve the purpose of promoting research in basic science and technology. encourage young researchers. He also expressed the view that “need to pay more attention to young scientists”. “I and other members are trying to propose to the Ministry of Science and Technology so that each industry has a young award and the young award recipient will be a typical scientist for his or her specialty.” Prof. Nguyen Huu Duc also expressed his support that next year the regulations should change a bit, such as increasing the number of young prizes, and some more detailed award criteria. “Currently, the criteria of the award are heavy on hard indexes such as the influence of magazines, and the ability to deeply analyze the value of each work still has some shortcomings. Therefore, in my opinion, it is necessary to balance the hard criteria with the specific value and unique points of the work, plus expert opinion, public opinion because there are works published in ordinary journals but very difficult. excellent”. Ta Quang Buu Prize is an annual award of the Ministry of Science and Technology to encourage and honor scientists who play a key role in excellent scientific works, carried out in Vietnam, and published on the Internet. prestigious international scientific journals in the field of natural sciences and engineering. The award has been implemented since 2013, in the past 7 years, it has received more than 360 applications, awarded 16 main prizes and 4 awards for young scientists.

Female scientist – Dr. Lu Thi Ngan (born 1983), working at the Department of Biology, Vietnam Museum of Nature, Vietnam Academy of Science and Technology is a female scientist of Thai ethnicity, born and raised in a highland district in western Nghe An . Since childhood, she has been associated with the farming life and nature. Maybe that’s why her love for forests and trees has existed for a long time. Dr. Lu Thi Ngan on a trip to find ferns in Pu Luong, Thanh Hoa Dr. Lu Thi Ngan “In the past, when I was a child, I ate sticky rice every day, so I was very healthy. In the early morning, I often followed my grandfather, my mother went to the forest. Everyone worked in the fields, and I sat next to the fields and waited until dark to return to the village. That day, I couldn’t speak Kinh fluently.” She added, fortunately when she was in high school, she was sent to study at the Central Ethnic Minority Boarding School located in Thai Nguyen. Her love for nature is infiltrated in her blood, so she is particularly interested in Biology and won the National Encouragement Prize for excellent students. Entering university, Dr. chose the Faculty of Biology, University of Natural Sciences, Vietnam National University, Hanoi and went to work at the Vietnam Museum of Nature upon graduation. Here, she decided to choose to study ferns, a small group of plants that are not of much interest. Dr. Lu Thi Ngan said that not only has no scent, no color, no flowers, fruits, and ferns, it is also a very difficult industry to study because the morphological characteristics change a lot, many features require a new magnifying glass and microscope observed, moreover, for this industry, there are very few researches in our country, so there is a lack of databases for reference. That’s not to mention, except for a few species of ferns that grow wild on the street that we often see, most of the unknown ferns grow in high mountainous areas, rugged limestone mountains. “But I still love ferns, because they have a fragile beauty with a hidden vitality,” she asserts. The “terrible” values Dr. Lu Thi Ngan said that although there is no fragrance, no color, no flowers or fruit, the fern brings values ​​that many people cannot imagine. Dr. Lu Thi Ngan on a field trip. Ferns are a group that plays a very important role in evolution and biodiversity because they are widely distributed and occupy many habitats. “This is the second largest group of vascular plants and one of the first terrestrial plants to appear, about 300-400 million years ago,” she said. In addition, ferns have many uses in everyday life. Few people know that ferns are a source of food containing a lot of nutrients. Some species of ferns such as bud, bubble, cow’s hoof… are valuable and nutritious food sources. The berries of some ferns can also be eaten to combat thirst. Many species of ferns can be used for ornamental or decorative purposes, and even the fibers of the fern can be exploited to make handicrafts. In particular, phytochemical studies on ferns have revealed that they contain many valuable substances that can be used to make medicine. On the market, there have been many medicinal products and functional foods derived from ferns such as sunscreen pills, hair growth shampoos, decoction forms to help increase resistance when infected with viruses, improve symptoms. dementia (Alzheimer). Not only the fern has “terrible” value, but the researches of Dr. Lu Thi Ngan about ferns is also very “terrible”. After more than 10 years of silent research, until now, Dr. Lu Thi Ngan has announced 5 new genera, 30 new fern species for science and 37 additional species for the flora of Vietnam. Her research results have contributed significantly to the worldwide community of fern scientists. At the same time, these results also help to enhance and confirm the biodiversity value of ferns in Vietnam. Every job has its own feelings There are consecutive articles published in domestic and foreign journals, including famous international journals, there are continuously announcements of new species discovery, but behind these are difficulties and difficulties. problems of scientists, especially female scientists. With Dr. Lu Thi Ngan every job has its own difficulties and hardships. Dr. Lu Thi Ngan said, up to now, she can’t remember how many field trips she has gone through, how many forests, and how many mountains she has climbed. But these trips are nothing compared to the time when she decided to go to Chengdu Institute of Biology, Chinese Academy of Sciences to be a PhD student. At that time, her life partner was Dr. Do Van Truong, who works at the Vietnam Museum of Nature, is working as a PhD student in Germany. And my daughter just turned 3 years old. It was like that for a few years as a family of three in three places. Recently, on his personal Facebook page, Dr. Lu Thi Ngan posted a photo of the three of them on her husband’s birthday with the caption, “This is the first time the whole family is together on a special occasion.” The line of confession is enough to understand the hardships of scientists. However, Dr. Lu Thi Ngan is very calm. For her, every job has its own difficulties and difficulties. The important thing is that I know how to overcome to do my job and love it. For her, doing science is not only a job but also a passion and certainly in the coming time, researches on Vietnamese ferns will continue to be published in international journals.

Assoc.Prof.Dr. Ngo Duc Thanh, Hanoi University of Science and Technology. (Photo: Bich Lien) That is shared by Assoc. Ngo Duc Thanh, Hanoi University of Science and Technology – a young scientist who has just received the nomination for the Ta Quang Buu Prize in 2021 announced by the Ministry of Science and Technology. Sincere and full of enthusiasm of the scientist who met us, Assoc.Prof.Dr. Thanh said: Global climate change (CC) is a contemporary challenge that humanity is facing. Many human and computational resources are focused by the world to make future climate change scenarios under different assumptions. In 2012, at an international conference in Vietnam led by Assoc. Ngo Duc Thanh co-organized, Coordinated Regional Climate Downscaling Experiments (Southeast Asia) project coordinated Regional Climate Downscaling Experiments (Southeast Asia) was established with the goal of sharing computational resources, human resources and promoting research for Southeast Asia. As soon as CORDEX-SEA was initiated, Assoc. Ngo Duc Thanh and his colleagues have embarked on research on simulating extreme temperature and precipitation factors for Southeast Asia. The study focuses on a number of climatic factors for the entire Southeast Asia region such as the number of heavy rainy days, the number of consecutive rainy or no rainy days, the number of days when the temperature is too hot or too cold … The program helped him to be named in the list of nominees for the Ta Quang Buu Award in 2021 – the project “Evaluation of the ability of the RegCM4 model to simulate the extreme indicators of rain and temperature in the CORDEX-Southeast. ASIAN”. According to Assoc. Ngo Duc Thanh, there are currently many models with different parameter configurations that can be used to calculate future climate change for the global as well as for individual regions such as Southeast Asia. However, different models will give different errors in different countries, regions, and times. During more than 4 years of implementation, Assoc. Ngo Duc Thanh and international colleagues conducted 18 simulation experiments to find the most suitable and optimal model configuration capable of representing the extreme climatic factors of rain and heat. area. 18 experiments were also ranked, from which the most optimal set of model parameters were selected, serving the long-term climate change projection until the end of the 21st century. After being announced, the work received the attention of the research community inside and outside the area. By providing the most optimal model parameters for long-term simulation experiments in Southeast Asia, the work is extremely important, helping to save significant resources and computation time. planning future climate change for the entire region. Initial research results are positive, but things have not stopped. Assoc.Prof.Dr. Ngo Duc Thanh said that, along with the results obtained, many big questions were re-opened: What is the cause of the difference in rainfall increase and decrease in different regions of the region? How do changes in the rain temperature regime affect extreme phenomena such as floods, droughts, hot weather …? However, the thing that Assoc. Ngo Duc Thanh feels most confident and confident that it is the handshake association of international scientists. Never before has the inter-country cooperation in the field been so extremely challenging as meteorology and climate change have been so closely coordinated. Talking more about the success of the project, Assoc.Prof.Dr. Thanh said: This is not only an honor for each individual scientist but also an opportunity for the field of meteorology / climate to be “quietly” and Picky learners, workers get more attention from society. Concerned about this field has not been concerned by many people, he expressed: There are very few young people interested in studying this field because this is also a challenging issue. “In recent years, each course has only recruited very few students, leading to this industry often scored relatively low, while the industry is in need of people who are good at math, physics and computer science.” In addition, during his work, he witnessed “inflows of people coming and going” in a number of hydro-meteorological research units, partly due to working conditions and inadequate income. living did not attract them. “We need the push to create a team of high-quality meteorologists that can be dedicated and passionate about the industry. That way can meet the needs of the society, solving practical and urgent problems such as forecasting natural disasters or researching climate change ”, Assoc.Prof.Dr. Thanh shared. /. The Ta Quang Buu Award is awarded annually by the Ministry of Science and Technology to honor scientists who have outstanding achievements in basic research in the fields of natural sciences and engineering. In 2021, together with TS. Bui Minh Tuan, Assoc. TS. Ngo Duc Thanh, a famous meteorologist was nominated for the “Main Award” category of this award. The Awards Ceremony is expected to be held on May 18 – Vietnam Science and Technology Day.

U.S. researchers found a corresponding decrease in size and body mass for babies when the baby’s mother consumed less than 200 milligrams of caffeine per day – about two cups of coffee – which is believed to increase the risk to the fetus. Smaller birth sizes can put babies at higher risk of obesity, heart disease and diabetes later on.

https://dulich.petrotimes.vn/

The team was led by Katherine L. Grantz, of the Internal Population Health Research Department at nih’s Eunice Kennedy Shriver National Institute of Child Health and Human Development. Dr Grantz said: “Until we learn more, the results show that you need to be cautious in limiting or completely eliminating those drinks that contain caffeine during pregnancy. Mothers should also consult a doctor about the consumption of caffeine during pregnancy”.

https://dulich.petrotimes.vn/

Previous studies have pointed to a link between consuming more caffeine (more than 200 milligrams of caffeine per day) during pregnancy with young children compared to gestational age (pregnancy stage) or having a risk of limiting growth in the uterus – located in the lowest 10th percentimal segment for babies of the same gestational age. However, studies of moderate daily caffeine consumption (200 milligrams or less) during pregnancy have showed different results.

Some found a similar increased risk for underweight babies and poor birth results, while others found no such link. The current study authors note that many previous studies do not take into account other factors that may affect the birth size of babies, such as changes in caffeine content in different drinks and mothers smoking during pregnancy.

https://dulich.petrotimes.vn/

For their study, scientists analyzed data of more than 2,000 racially and ethnically diverse women at 12 medical facilities who were enrolled between 8 and 13 weeks of pregnancy. The women do not smoke and do not have any health problems before pregnancy. Between the 10th and 13th weeks of pregnancy, the women were given a blood sample that was then analyzed for caffeine and paraxanthine, a compound produced when caffeine decomposes in the body. These people also said they consumed drinks containing caffeine daily (coffee, tea, soda and energy drinks) in the past week – once when they signed up and periodically throughout pregnancy.

https://dulich.petrotimes.vn/

Compared to babies born to women who did not have or did not have a minimum blood caffeine concentration, the babies were born to women with the highest blood caffeine levels at birth who were 84 grams (about 3 ounces) lighter on average, 0.44 cm (about 0.17 in) shorter, and had a head circumfervity less than 0.28 cm (about 0.11 inches).

Based on women’s own estimates of the drinks they drank, women who consumed about 50 milligrams of caffeine a day (equivalent to half a cup of coffee) had babies 66 grams (about 2.3 ounces) lighter than babies born to those who did not use caffeine. Similarly, babies born to caffeine consumers also have thigh rings smaller than 0.32 cm (about 0.13 inches).

https://dulich.petrotimes.vn/

Caffeine is believed to cause blood vessels in the uterus and placenta to shrink, which can reduce the amount of blood supply to the fetus and inhibit development. Likewise, researchers believe caffeine may have the potential to disrupt fetal stress hormones, put babies at risk of rapid weight gain after birth and cause obesity, heart disease and diabetes later on. They also concluded their findings suggested that even moderate caffeine consumption may be associated with a decrease in fetal development.
