Framatome sent a warning letter to the US government. In the letter, Framatome asked for the support of the US Department of Energy, according to CNN. Framatome is the company that helped build and provide technical support for the Taishan nuclear plant, located about 130 km west of Hong Kong. CNN added that Washington must “hold a number of high-level meetings and discussions with Paris after receiving the letter”. At the same time, the US and Chinese authorities also “contacted to discuss the matter”. Even so, US officials do not believe the situation poses a serious safety threat to residents or workers at the plant. Framatome (France) warned of an “imminent radiation threat” at the Taishan nuclear plant in Guangdong province. Photo: Power-Technology China General Nuclear Power Corporation (CGN) later announced on Taishan’s website: “Taishan’s Unit 1 is operating normally and Unit 2 was reconnected to the grid last week. before and after the overhaul”. These units have a total capacity of 3.3 gigawatts and entered service in 2018 and 2019, respectively. CGN owns a 51% stake in the Taishan joint venture. Framatome’s parent company, Electricite de France SA (EDF), holds a 30% stake, with the rest belonging to Yuedian Utilities (China) in Guangdong province. Framatome claims it is “assisting in resolving the performance issue related to the Taishan nuclear power plant”, while citing available data showing that “the plant is still operating within safe parameters”. The EDF on June 14 confirmed that there was an “increase in the concentration of noble gases” in the cooling system of the Taishan plant. “The presence of some noble gases (chemically inert elements such as argon, helium or neon) is a phenomenon that has been observed during reactor operation,” the EDF said. The information was published at a time when the province of Guangdong, China’s industrial center, suffered a power shortage, forcing more than 20 cities to split electricity to a number of companies and factories. China is the world’s third-largest nuclear power market, after the US and France, with many new reactors under construction. The country has not recorded any serious nuclear accidents.

1. When did the earliest models of air conditioners appear? Icon Ancient Egypt Icon Ancient Roman The correct answer is answer A: According to research by archaeologists and historians, the most primitive model of air conditioners appeared from ancient Egypt. To cool the indoor air and avoid the hot and dry desert climate, the ancient Egyptians hung bundles of water-soaked reeds in the windows. When the wind blows through the window, it will bring water vapor into the house. Another way of cooling the ancient Romans was that they surrounded the walls of the house with plumbing, when the water circulated, it would cool the house. Water cooling was also adopted by the medieval Persians. Their system includes wind towers and water tanks that help cool the indoor air. 2. Who came up with the first idea for an air-cooling system? Icon Michael Faraday Icon John Gorrie Icon Benjamin Franklin The correct answer is answer B: Scottish physician John Gorrie (1803-1855) Scottish physician John Gorrie (1803-1855), who gave the first idea of ​​the air-cooling system. Although the model and ideas above were never realized, in 1851, Gorrie was still awarded a patent for a machine that made ice. 3. Who invented the model of air cooling by adding salt to water as it evaporates? Icon Cornelis Drebble Icon Michael Faraday Icon Benjamin Franklin The correct answer is answer A: Beginning with the inventor Cornelis Drebble (1572-1633), he invented a model for cooling the air by adding salt to water as it evaporates. They were introduced to the then king of England, James I, but were not taken seriously. In 1758, the governor of Pennsylvania, Benjamin Franklin (1785-1788) and Professor of Chemistry John Hadley (1731-1764) at Cambridge University experimented and discovered the principle of reducing heat from evaporation. This was an important invention that laid the foundation for later air conditioners. Both Franklin and Hadley realized that the evaporation of a liquid such as alcohol or ether could lower the temperature of an object below the freezing point of water. Both men successfully experimented with evaporation to reduce the temperature of a mercury thermometer tube from 18 degrees Celsius to minus 14 degrees Celsius. By 1820, the British chemist Michael Faraday (1791-1867) made it. successfully experimented with compression and liquefaction of ammonia gas. During his experiments, he realized that evaporating liquid ammonia could cool the surrounding air, and this was one of the premise for later air conditioners. 4. Who first invented the modern air conditioner? Icon Willis Carrier Icon John Gorrie Icon Benjamin Franklin The correct answer is answer A: In 1902, Willis Carrier (1875-1950) invented a model of the air conditioner while working for the Buffalo Forge mechanical company. Willis Carrier was born in New England state (USA), from a young age, she was smart and bright. After graduating from Cornell University, Mr. Carrier worked in a heat-resistant suit. His research saves the company $40,000 per year. With this invention, Carrier is known as the father of the modern air conditioner model that we are using. However, Carrier’s air conditioning system is very large, noisy, extremely expensive and very dangerous because it uses the toxic chemical ammonia to cool the air. In 1911, Carrier continued to introduce “refrigerant formulations with reasonable humidity ratio”, this method of refrigeration is still used in some areas of the refrigeration industry. 5. Where was the Willis Carrier air conditioning system first used? Icon A movie theater Icon A printing factory Icon On the bus The correct answer is B: Willis Carrier’s air conditioning system is used in a printing factory. This system helps control the temperature and also keeps the humidity in the plant. Carrier’s principle of humidifying the air is quite simple, instead of pushing air through the heating tube, the air flowing through the tube is cooled by liquefied ammonia. 6. In what year was the Carrier-built air conditioning system first installed in a home in Minneapolis? Icon 1913 Icon 1914 Icon 1915 The correct answer is B: In 1914, a Carrier-built air conditioning system was installed for the first time in a house in Minneapolis. This machine is 2.1 meters high, 1.8 meters wide and nearly 7 meters long. But this machine has never been used because no one lives in the house. However, homeowners still have to spend more than 60,000 USD per year to maintain the entire house. 7. When was the first movie theater in the US equipped with air conditioning? Icon 1917 Icon 1918 Icon 1919 The correct answer is answer A: The household air conditioner has a height of 2.1 meters, a width of 1.8 meters and a length of nearly 7 meters. However, it has never been used because no one lives in the house but, the owner is a famous gambler who is rich and spends more than $60,000 annually on maintenance. From 1917 to 1930, the cinema was a place for people to enjoy the air cooled by air conditioning. The first movie theater in the US to be equipped with air conditioning was the New Empire Theater in Montgomery, Alabama in 1917. In that year, the Central Park Theater in Chicago also installed an air-conditioning system, which was enthusiastically received by customers. . Especially on summer days, the air conditioner is even more effective. In 1922, Carrier continued to make two breakthroughs in air conditioning. The first is that he replaces the toxic condenser ammonia with another, safer compound, dielene (dichlorethylene). 8. In 1969, the cooling system was fitted in Neil Armstrong’s spacesuit when performing a Moon walk, is it true or false?

These two astronauts wore them while on the Moon walk. Result Please work harder! point

Landmark 81 has a total of 81 floors, 461 m high. This is the tallest building in Vietnam, located in the center of Binh Thanh District, Ho Chi Minh City. The maintenance and technical maintenance of the entire building is performed daily by the management team and staff. Anh Vu – the technical manager of the Landmark 81 building, said that the technical team often had quick briefings early in the morning to determine the arising work to do during the day. At the same time, the technical status of the building, the work done in the previous day must be reported in detail. After that, the group of employees moved to the 79th floor of the building. This is the highest floor accessible by elevator. After that, people will walk up to the 80th and 81st floors (top floor) of the building to do their assigned work. Check the building’s power supply system. All electrical specifications must ensure safety conditions in accordance with regulations. Technical staff use specialized temperature gauges to check the heat at conductor structures and power-using equipment on the 80th floor. This is a routine job to promptly detect problems and limit problems. minimize the risk of accidental fire or explosion. A group of workers periodically maintain the glass. To do this, the worker must move on specialized rigs, in turn, check all the glass panes. The outer glass of the building is reinforced with special materials, ensuring safety and durability. Workers check a building’s cooling system. The staff checks the operating parameters of the elevator. “The building is tall, the elevator is an indispensable element in the operation. We understand this, so we should pay attention to the daily maintenance and technical maintenance, so that the elevator does not cause problems,” said Mr. Vu. to speak. The elevator of Landmark 81 building has a pulling force of 12,500 kg, each car has a load of 2,000 kg, a speed of 5m/s – is one of the fastest elevators in Vietnam. “Working on high-rise buildings requires us to have good health and overcome specific limitations. For example, when it comes to glass maintenance, every worker must overcome fear, focus on work and comply with all protection principles to ensure safety,” said Quang Trung, a technical staff member. Periodic inspection and technical maintenance is carried out in the early morning hours, or when people take a lunch break. Troubleshooting was also implemented urgently. This helps the building operate in a safe condition, and at the same time does not affect the activities of residents, merchants and visitors.

Raising pigs in a closed cold barn is a new direction in livestock development In 2019, according to professional statistics, Thap Muoi had nearly 10,000 pigs of 406 households destroyed due to African swine fever. Like other pig-raising households, Ms. Luong Thanh Huong’s farm of nearly 500 pigs in Hamlet 3, Tan Kieu Commune also destroyed 164 pigs, it is worth mentioning that in the same place, but the cages are raised in the traditional form. disease, and the cage in the form of a closed cold barn (just a few meters away) was completely unaffected. Ms. Huong said that last year, due to the African cholera epidemic, her traditional farm was also affected by the disease and had to be destroyed a lot, but in the form of a closed cold barn, she was not affected. rebuilt the barn, raising all in the form of cold barns. Raised in this form, pigs grow quickly, reduce a lot of costs and are consumed at a higher price than the market. The closed cold barn system is divided into 3 areas including: food processing area, pig raising area and biogas cellar complex to treat manure and wastewater. This is a modern farm with full equipment such as water cooling system, exhaust fan, automatic feeding and drinking trough, automatic temperature control system inside… Model of the barn. closed cold, the temperature is always stable, the pigs are less tired due to the influence of the hot sun, helping the pigs to exercise well, eat well and grow stably, less effort to take care and clean pigs should be consumed with price is higher than the market. Therefore, there are many breeding households coming to learn the model of livestock by a closed cold barn system. Also a large pig breeder, Ms. Nguyen Thi My Em from Hamlet 4, Tan Kieu Commune is intending to rebuild the barn in the form of a cold-closed barn, but is still facing financial difficulties. Raising pigs in a closed cold barn system is a new direction in livestock development today, but the initial investment is relatively large. Mr. Nguyen Hong Sang – Deputy Head of Technical Training and Technology Transfer Department, Thap Muoi Agricultural Service Center said: “Effectiveness when raising livestock in the form of closed cold cages is clear, but the common difficulties of farmers are obvious. raising livestock in the district is the source of capital, because raising according to this model requires relatively large capital. Dong Thap also has policies to support the development of household livestock production, but it is difficult for people to access this capital due to the habit of small-scale livestock production, which the policy is bound to be on a large enough scale, depending on the type of livestock. but have different regulations, must link consumption, environmental protection issues… so it is difficult for people to access”. In order to keep livestock from being affected by the epidemic, ensure environmental hygiene, safety and efficiency, in the coming time, Thap Muoi needs to strengthen the propaganda to change the practice of small and fragmented livestock to form of farm farming, concentrated, self-contained, sustainable livestock production.

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.

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.
