Hybrid electric vehicles (HEV), which have maximum fuel economy, low emissions and smooth operation, are suited to Vietnam’s climate and transport conditions, experts say.

Hybrid electric vehicles to account for 30% of market by 2030

Auto manufacturers are trying to make environmentally friendly and fuel-saving cars by pursuing electric models, which are becoming the flagship models of many manufacturers.

Electric vehicles are classified into four groups: HEV, PHEV (plug-in hybrid electric vehicle), BEV (battery electric vehicle) and FCEV (fuel cell electric vehicle). The core parts are an electric engine, battery and electricity storage unit.

According to Bloomberg news, by 2030, the global market will have more than 90 million electric cars, of which HEV and PHEV will become the major line before shifting to BEV and FCEV.

The major difference between HEV and other electric vehicles is that the former does not need plug-in for recharging. Batteries will be charged thanks to energy recalled when the vehicles slow down or break, or by petrol-engine kinetic energy. The additional power will be provided to vehicles when they start, operate or speed up.

Under Vietnam’s conditions, experts believe that the popularity of BEV won’t be high because this depends on road conditions, infrastructure, charge stations and people’s habits. They believe that HEVs will be more suited to Vietnam and have great potential to develop in the near future.

Vivek Vaidya from Frost and Sullivan said at a workshop about the efficiency of hybrid technology on March 30 that hybrids will be the biggest car market segment in the next 10 years in Vietnam, expected to account for 30.4 percent of total cars by 2030.

The expert said no single solution or technology can win in the competition among electrified vehicles. They need to be combined to exist internationally, depending on the specific characteristics and development strategies pursued by every country.

Experts estimate that hybrids in Vietnam accounts for 0.3 percent. Meanwhile, Thailand, which has similar conditions to Vietnam, has 35,000, or 3 percent.

Hybrids save 60 percent more on fuel than petrol cars

Dam Hoang Phuc from the Hanoi University of Science and Technology, reporting about trial of hybrid technology in Vietnam’s conditions, said HEVs have outstanding advantages over petrol-run cars.

Researchers found surprising results when they compared two Toyota Corolla Cross, one using a petrol engine and the other HEV technology during the first research phase which lasted two months.

On inner-city roads, HEV consumed 5.6 liters per 100 kilometers in rush hours, 4.8 liters in normal hours and 4.6 liters on highways. Meanwhile, the figures were 10.3 liters, 11.2 and 5.7 liters, respectively, for petrol-run cars.

Regarding emission quality, HEVs were permitted to cut 18.5-57.4 percent of the volume of toxic gas emitted into the environment. HEV’s brake was also more effective, and there was no difference in feeling when driving.

Since hybrids don’t need special infrastructure conditions, they are believed to be suited to Vietnam’s transport situation and will reduce the impact of climate change in the country.

First hybrids were brought to Vietnam in 2009. At that time, Lexus RX400h and LS600hL were favored by wealthy people. In 2010, Mercedes Benz S400 Hybrid was launched by the manufacturer in the local market.

However, experts say that the biggest barriers are the high selling prices and expensive spare parts. If Vietnam wants to popularize hybrids, it needs to offer more tax incentives. .

Petrol-and-electricity run cars which consume petrol no higher than 70 percent of total fuel now enjoy a preferential luxury tax, 70 percent of internal combustion engine cars of the same types.

VinFast, the Vietnamese automobile manufacturer, has signed an MOU on strategic cooperation with Taiwanese ProLogium Company to manufacture solid-state batteries for electric cars.

Vietnamese YouTubers claim they no longer produce content but videos still appear

Most owners of the videos with titles “delete channel” and “last videos” on YouTube are still operating.

Vietnamese YouTubers claim they no longer produce content but videos still appear

Tho Nguyen last month decided to delete or hide all her videos and stop producing YouTube content

Tho Nguyen last month decided to delete or hide all her videos and stop producing YouTube content after the scandal related to the posting of a clip in which she was beseeching a doll to grant luck to students who have to attend upcoming exams.

More recently, ViruSs (Dang Tien Hoang) on April 1 stated he will erase the channel to renew himself. Prior to that, many disreputable YouTubers, including NTN, many times announced the leave. However, their video still appears regularly.

Vu Hung from Hoc Vien YouTube (YouTube Creator Academy) with 150,000 members commented that this is commonly seen, saying that content producers need to play tricks to attract viewers, because the more viewers, the bigger money they earn from ads.

According to Hung, when announcing their retirement from content production, YouTubers can attract old followers who have not accessed their channels for a long time, and now want look again to find out what is going on.

This is a good way to increase the number of interactions for the channels, which have high numbers of subscribers but have seen number of views decreasing because of algorithm changes, consumer behavior, overlapped content scanning, and copyright problems.

According to Hung, the decision of Tho Nguyen to stop producing content and hiding her video clips to avoid negative reports and public pressure, was a wise move.

ViruSs and NTN (Nguyen Thanh Nam) are similar cases. “They stopped producing content on their channels to avoid additional reports,” he said.

And when old channels reappear, content producers can lure high numbers of viewers back and fans will be willing to click ‘follow’ again.

Hung noted that there is a difference between Vietnamese and foreign viewers. Vietnamese viewers are not as choosy when deciding to follow channels. In many cases, they click ‘follow’ just because of the invitations of channels’ owners.

Meanwhile, in YouTubers’ groups, members invite each other to subscribe, and buy views and subscribers. The announcement about content production therefore has little significance.

Nguyen Hai (Rikaki Gaming, 1.62 million subscribers), a creator, said these YouTubers are rich but still have to produce clips to attract views.

“YouTubers will ‘retire’ only if no one is interested in them, and they won’t stop working just because of scandals or criticism,” Hai said.

HÀ NỘI — The Steering Committee of the project ‘Support to Việt Nam for the Implementation of the Paris Agreement’ (VN-SIPA) held its second meeting in Hà Nội yesterday with the participation of representatives from ministries, sectors, and localities.

Addressing the meeting, Deputy Minister of Natural Resources and Environment Lê Công Thành highlighted the project’s support in implementing Việt Nam’s nationally determined contributions (NDC) and the Paris Agreement on climate change.

To speed up the project, he asked participants to make proposals and discuss the 2021 plan, especially activities relating to State management of climate change and enhancing Việt Nam’s role and responsibility as a signatory to the Paris Agreement and the UN Framework Convention on Climate Change (UNFCCC).

Weert Borner, Deputy Ambassador of Germany in Việt Nam, noted Việt Nam was one of the first countries to build an action plan to realise the Paris Agreement and one of the first to submit and update its NDC.

He said the VN-SIPA supports Việt Nam in creating the necessary conditions for the deal, to mitigate the impacts of climate change and bring environmental and socio-economic benefits for the country.

Phạm Văn Tấn, Vice Director of the Climate Change Administration at the Ministry of Natural Resources and Environment, said as COVID-19 is still a major issue, ministries and localities should prepare alternative measures and speed up the implementation of approved plans.

Kia Fariborz, Chief Advisor of the VN-SIPA project, said last year, Việt Nam completed and updated its NDC report in September, a move lauded by the international community as it was one of the first 20 countries to do so.

The four-year VN-SIPA project was approved by former Prime Minister Nguyễn Xuân Phúc on April 3, 2019, and has a total cost of 10.3 million euros (US$12.31 million), funded by non-refundable official development assistance (ODA) from Germany. It aims to strengthen the legal framework and national capacity in implementing the Paris Agreement, with the core conducting Việt Nam’s NDC.

So far, it has assisted in the building of a climate change programme in the revised Law on Environmental Protection 2020 as well as climate change management documents and sectoral plans for climate change response. It has defined solutions in the central provinces of Quảng Bình and Hà Tĩnh based on their local ecosystems. —

Female scientist with PhD in immunology pursues research on rare diseases

Published

on

Tran Nguyen Kim Thi is a postdoc majoring in AI usage in medicine at the Huge Kaul Precision Medicine Institute at the University of Alabama in Birmingham (UAB) in the US.

Female scientist with PhD in immunology pursues research on rare diseases

She obtained a doctorate in immunology in 2020 with research work on the factors of the immune system that affect chronic lung diseases.

Her research found that in patients suffering from uncommon pulmonary fibrosis of unknown origin, their immune systems have a variety of disorders that lead to immune cells attacking their lungs. The damages that accumulate over time turn into hard scarring that replaces normal lung tissue, impairing the lung’s air exchange function.

“The result of the research has been used by Prof Steven Duncan, my teacher, to apply therapies or drugs that eliminate or inhibit the production of new antibodies to treat patients with severe pulmonary fibrosis,” she said.

“Clinical experiments show very satisfactory results. About 50 percent of serious patients under the treatment of the professor have shown improvements. Some people who seem to be dying can get up and walk,” she said.

However, Thi did not continue the project for her postdoc research. She decided to shift to do research on the application of AI in biomedicine. She no longer carries out experiments at biochemical laboratories, but does mostly programming at the computer.

“There is a bitter truth that the percentage of successful research in biomedicine laboratories, as well as other experimental sciences, is very modest. About 90 percent of projects of new researchers fail. There are researchers who still cannot gain achievements after five years to complete their doctoral course,” Thi said, explaining her decision.

Another reason that led to her shift was that she believed she could help many people more directly and quickly with her current work – using AI in medicine to treat patients suffering from uncommon diseases, than by implementing biomedical projects as she did in the past.

Previously, her research was in severe and uncommon chronic lung diseases, including pulmonary fibrosis of unknown origin which has the rate of 1/10,000 people a year.

Now her research is applied to very rare diseases, with only few individuals in the world have, mostly because of genetic causes. The symptoms of the diseases show very early. Patients’ relatives come to precision medicine institutes to find the answers why their children have the disease.

Liberal education

“I believed that studying at the (liberal arts) school would promote my abilities. If I had studied at a normal school, I would not have followed the path of doing scientific research that I am doing now because of the common thought that women should study economics, trade or finance,”

Tran Nguyen Kim Thi

Fifteen years ago, Thi, who was a ninth grader at a small school in Di Linh, Lam Dong province, decided to leave her hometown for Da Lat City to study at the city’s school for the gifted.

After finishing high school, she passed the entrance exam to the Foreign Trade University, a prestigious school. However, she left the school after one semester, which was a shocking decision in the eyes of her friends and relatives.

She then spent time on learning English, attended standardized tests, prepared essays and searched for information to apply for full scholarships.

Thi chose St John’s College, a liberal arts school, which offered a scholarship of $200,000 for four-year study.

“I believed that studying at the school would promote my abilities. If I had studied at a normal school, I would not have followed the path of doing scientific research that I am doing now because of the common thought that women should study economics, trade or finance,” she said.

When following tertiary education, Thi spent her internship at a lab on immunology because she once suffered from an autoimmune disease.

“When learning about my disease, I read a lot of documents and found it very interesting, so I decided to study immunology in the second year at school,” she recalled.

Thi got a letter of introduction from a teacher, which helped her obtain a scholarship.

When asked if it was hectic doing and studying many things, she admitted that she sometimes felt giddy.

“However, modern society needs people with specialized knowledge and broad knowledge. It would be better if you have deep and broad knowledge. For me, broad understanding both helps society and makes my life more interesting,” she said.

Thi’s life can be seen in her images of a young, healthy woman on her personal page. She travels, does physical exercise, participates in festivals, and has a special passion for dancing.

Because of her appearance and personality, she sometimes has trouble because she “does not look like a researcher”.

“Asian people are thought to study well, work hard, have few opinions, and be reserved. But I don’t look like this,” she explained.

Thi is now striving for a balanced life and doesn’t spend all her time on her career.

“I believe that I will learn all my life. I realize that what I like to do is to learn. But this doesn’t mean that I have to study at school, because there are many ways to learn. You can learn something from an article in a fashion journal,” she said.
