Bananas contain a radioactive element. Scientists from Beijing University of Aeronautics and Astronautics Zhang Xiaotian and Liao Jie discussed this in an article for WeChat.
Experts have found that in addition to regular potassium, bananas contain its isotope & mdash; potassium-40, a source of ionizing radiation. However, there is very little of it in the fruits.
“ The radiation dose received from eating a banana is approximately 0.0778 microsievert. This is & # 39; negligible & # 39 ;, & ndash; the scientists explained, adding that a CT scan of the chest for this indicator is equivalent to 70,000 bananas.
Previously, the nutritionist spoke about the risks of excessive consumption of apples. Fruits, among other substances, contain many organic acids that speed up metabolism. But in addition to the benefits, they can lead to some unpleasant sensations when it comes to people with high acidity.
Deputy Defense Minister Alexei Krivoruchko reported deep & nbsp; modernization of MiG-31 fighter-interceptors. The revision of these planes with an improvement to the level of the MiG-31BM is in progress & nbsp; at the 'Sokol' aircraft factory In Nizhny Novgorod. It is assumed that the modernization will significantly increase the combat capabilities, it will be able to destroy all air targets & mdash; ranging from drones and cruise missiles to hypersonic planes.
The overhaul with modernization of each aircraft takes about a year. During this time, the interceptors completely change the on-board equipment, the cockpit canopy and the wiring. The glider, which is made of titanium, is being stowed away. This metal has an almost unlimited resource, however, some aircraft require replacement of the coating. The integration of modern aeronautical weapons is also underway. In particular, the mechanical control system is changed to a fly-by-wire, for which on-board computers are installed on board.
Previously, discussions had taken place on the fate and timing of the decommissioning of these interceptors. In particular, they consume a lot of fuel – a full refueling is about 15 tons, about 10 tons are spent per hour. & Nbsp; The State Duma Defense Committee even held special hearings on the MiG-31. As a result, they started to modernize again. It started in 2011, and is currently under repair on the MiG-31B fighter and reserve at the MiG-31BM level. Under two contracts, the Department of Defense ordered the upgrading of a total of 114 interceptors for the aerospace forces and the navy. The upgraded MiG-31BM has received an updated radar, which allows you to see the enemy at a distance of up to 320 km and destroy it with long-range missiles at a distance of 280 km . The new gun control system made it possible to equip the vehicle with more modern ammunition. Currently, development of ultra-long range air-to-air munitions is underway for interceptors.
In 2018, the MiG company completed the creation of a special modification of the MiG-31K. Its hallmark is the equipment with hypersonic air ballistic missiles “ Dagger ''. to attack ground targets. The hunter received new on-board equipment, increased fuel supply, and special communication gear. Since 2018, ten MiG-31Ks have been in experimental combat service in the Southern Military District.
MiG-31 & mdash; fighter-interceptor developed by the USSR for air combat in the 70s of the last century. It is the largest aircraft of this class in service with countries around the world. All MiG-31BMs in service were built in the late 1980s & mdash; early 1990s. Their lifespan is limited to 2.5 thousand flight hours; the issue of its one thousand hour extension is currently under consideration, which will allow the interceptors to remain in service until at least the mid-2030s. At that point, the MiG will become the one of the oldest types of combat aircraft in service with the Russian aerospace forces.
Due to its mass of over 46 tons, the aircraft is classified differently from conventional fighters. The pilot of a two-seater aircraft, the only one in operational-tactical aviation, is officially called the pilot-in-command. Only pilots of heavy bomber and transport aircraft have this privilege. & Nbsp;
The MiG-31 still carries the title of the fastest fighter in the world. Maximum flight speed and ndash; 3 thousand kilometers per hour. The aircraft is designed to intercept and destroy targets, including cruise and ballistic missiles, at extremely low, medium and high altitudes in simple and difficult weather conditions. Earlier, foreign experts drew attention to & nbsp; for the expanded arsenal of MiG-31BM and MiG-31BSM interceptors, including the new R-74M short-range air-to-air missile, which makes the MiG-31 one of the most versatile.
Today & nbsp; The MiG-31BM is considered the most effective fighter in air combat. He is right behind the fifth-generation Su-57 aircraft. By 2030, Russia is expected to commission a whole new class of interceptors. The upcoming sixth generation MiG-41 fighters are expected to be able to fight even in near space. The interceptor will be able to fly at hypersonic speeds, twice as fast as the current MiG-31.
The Soviet Union also existed & nbsp; interceptor modernization program, but the collapse of the USSR prevented the implementation of the MiG-31M, the project was canceled in 1995 after several successful flight tests due to the economic situation in Russia . The MiG-31 was more expensive to manufacture than the Su-27. After the collapse of the USSR, Russia decided to focus on universal models. Although the Su-27 was inferior in features to the MiG-31, it was easier to adapt to various military tasks.
During the survey, the Russians indicated which occupations they considered to be the most overvalued in the country. The results of & nbsp; SuperJob search service quotes & nbsp; RT.
22% of 1,600 people questioned spoke of unjustified salaries for MPs and politicians. Russians also consider the work of civil servants to be overrated (14%). The third place is occupied by top managers, whose salaries are considered too high by respondents (9%) & Nbsp;
managers (4%). Bloggers' fees were considered too high by 2% of respondents. & Nbsp;
Another 16% said that real estate agents, bankers, hairdressers, lawyers, psychologists, coaches, builders and dentists receive unreasonably high salaries. & nbsp;
Only 4% of citizens expressed the opinion that all work should be well paid. & nbsp;
Earlier it was reported that Russian President Vladimir Putin had demanded to ensure a living wage level for public sector employees. He said they should receive payments of the amount provided in the decrees of May 2012.
Authorities in Hong Kong have decided to toughen quarantine measures against passengers arriving from eight southern African countries, the newspaper reported. Dimsum Daily.
As of November 28, citizens arriving from South Africa, Botswana, Eswatini, Lesotho, Malawi, Mozambique, Namibia and Zimbabwe must undergo their first week of quarantine in a dedicated government quarantine center. They can spend the remaining two weeks in hotels.
This decision was taken in the context of the detection of a new strain of the omicron coronavirus. Two cases have already been recorded in Hong Kong. One was imported, the other occurred in an airport quarantine hotel: a passenger from South Africa infected a passenger from Canada. It should be noted that both patients were vaccinated.
Previously, authorities in Germany, Austria and the Netherlands have reported probable case detection of a new variant of & nbsp; COVID-19.
Recall that Russia will restrict the entry of foreigners living in Hong Kong and nine countries in southern Africa. & nbsp; Read the details & nbsp; in the material of AiF.ru.
Scientists from the Tupolev Kazan National Technical Research University (KAI) have designed a supersonic aircraft for intercontinental flights in the stratosphere, follows a paper posted on Rospatent's website. Due to the increased altitude, the flight will be fast and special technical solutions will reduce energy costs. However, their use will be more expensive than the launch of a conventional aircraft, most likely, stratoplanes will be used in extreme situations, when the speed is more important than the resources expended.
Recall that the stratosphere & nbsp; & mdash; This is a layer of the atmosphere located at a & nbsp; height of & nbsp; 11 & nbsp; to & nbsp; 50 & nbsp; km. In the rarefied upper layers of the atmosphere, movements at speeds & nbsp; supersonic and & nbsp; hypersonics are facilitated, thus significantly reducing flight time over long distances. For intercontinental flights, this will save significant time. A flight between nearby points across the stratosphere is impractical: too much time and fuel will simply be spent raising the aircraft to sufficient altitude.
By the way, the development will be useful for Russian-wide flying: the ability to quickly deliver people and goods to remote areas of the country is vital in emergency situations (fires, floods, other natural disasters). Yet the distance between the settlements & nbsp; RF is sometimes & nbsp; greater than the distance between the continents.
The stratolet (as the device was called) will consist of a & nbsp; fuselage with & nbsp; fenders, horizontal control surfaces in the front and & nbsp; in the rear, combined missile or air rocket engine on & nbsp; oxygen and & nbsp; upper floor. Two gas turbine engines and a fuselage engine fairing will be attached to the engine fairing.
As the developers note, the technical solutions they came up with will create a machine that will stand out from foreign competitors with increased payload and reduced take-off time. They christened Reaction Engines Limited's Reusable British Unmanned Spacecraft Project Skylon, which is expected to take off in the air in the mid-2020s.
As stated in the patent, the British device has the following shortcomings: low engine efficiency at subsonic speeds and & nbsp; low supersonic speeds, excess weight, which is caused by the increase in the wing area of an aircraft from & nbsp; horizontal take-off on & nbsp; ground. In addition, the car will have to spend a lot of time on & nbsp; acceleration and & nbsp; separation of the track or even resort & nbsp; using special take-off carts.
The Russian stratolette will be able to get rid of these defects thanks to the principle of flight in two stages. For this reason, the fuel fill mass of the last stage will decrease and the payload will increase.
The oval shape of the upper stage wing will give extra lift. Thus, the time that the glider will spend on take-off will be reduced. At the same time, the principle of two-stage flight allows the use of powerful engines installed on the overturned upper stage.
Also, the concept of suborbital flights, which is even more technically complex and & nbsp; expensive, is gaining popularity. Recall a number of recently thundered projects all over the world from the United States: these are Jeff Bezos with his vertical lap that jumps up to 80-90 km, and Branson with a rocket plane for tourist departures to & nbsp; 100 & nbsp; km with & nbsp; 10 minutes in zero gravity … The furthest went Elon Musk with & nbsp; taking off vertically and & nbsp; while implementing a once landing STARSHIP rocket. But & nbsp; for suborbital flights, it is necessary to solve many problems, & nbsp; mainly related to & nbsp; Powerful hypersonic motor running reliably, with thermal protection and l & nbsp; safe entry, and & nbsp; also when braking in & nbsp; atmosphere and & nbsp; reliable landing. In & nbsp; Russia, the hypersound is still in use for military projects.
It is obvious that & nbsp; stratoplanes will only be available to people with a & nbsp; heavy wallet or state & mdash; perform operations for & nbsp; rescue people.

Every year, Mother's Day is celebrated in & nbsp; the last Sunday of November in Russia. & Nbsp; this year is the & nbsp; 28 & nbsp; November.
Mom & nbsp; & mdash; the main person in everyone's life. National project “ Demography '' takes care of & nbsp; families with & nbsp; children, by helping financially in the & nbsp; first years after the birth of a child. Modern and cozy kindergartens with groups of day care centers are opening all over Russia, giving women the opportunity to return to work earlier if they wish. And & nbsp; if mom wishes, the national project will help you learn a new trade for free, improve your skills or even start your own business.
Thanks to the national project, families receive payments for children under 3 years old. Monthly payments can be arranged by families whose income is less than two living wages per person. The amount of payment is equal to the regional subsistence minimum for children, in & nbsp; average in & nbsp; country & nbsp; & mdash; 11.4 & nbsp; thousand. rubles, and & nbsp; for & nbsp; his & nbsp; appointment, you must contact the & nbsp; MFC or the social welfare agency of the & nbsp; place of residence.
In & nbsp; Irkutsk region 19 & nbsp; 071 large families receive additional financial support. Mother of many children Tatyana Garaeva , raising four children, says: “A large family is always expensive. Considering mom isn't always at work and busy raising kids, dad has to work more often. And & nbsp; It is great that the government is giving us substantial support by setting additional installments. ”
For the Volgograd region, the size of the average family income per capita for the purpose of paying & nbsp; children under & nbsp; 3 & nbsp; years in & nbsp; this year is 21 & nbsp; 784 & nbsp; rubles, and & nbsp; the payment itself is 10 & nbsp; 414 & nbsp; rubles. One of its & nbsp; recipients are Olga Topilina, a resident of the village of Nekhaevskaya … & laquo; To our firstborn & nbsp; & mdash; two with & nbsp; half a month. The child gives us a new reason to rejoice every day. Of course, we love our little miracle and try to surround it with full care. And & nbsp; monthly payment here & nbsp; & mdash; very good help. For example, the funds received go towards the purchase of diapers, clothes. Any mother knows how fast babies grow. So we have to change our outfit every month. With monthly support, we & nbsp; & nbsp; have no problem at & nbsp; provide Serezha with everything he needs & nbsp; & nbsp; & mdash; a young mother shared.
With the support of the national project “ Demography '' throughout the country, modern kindergartens with kindergarten groups are being built, ensuring the availability of preschool education for all children under 3 years of age , regardless of place of residence, and mothers, if they wish, to go to work earlier. Already, 170,000 crèche places have been opened in & nbsp; Russia.
In the Volgograd region, Novonikolaevsky working village, the inauguration of a new kindergarten for & nbsp; 144 & nbsp; places took place. In a two-story building, modern conditions were created for educational activities, nutrition, sleep, health protection, a natural history room, a music room, a gym, offices for a speech therapist and a teacher-psychologist are provided. “ This is a great support for us, & nbsp; & mdash; sharing local resident Maria Kosivtsova . & mdash; & nbsp; And & nbsp; we & nbsp; are happy that our children now attend a modern kindergarten and & nbsp; Magnificent. By & nbsp; more & nbsp; its opening will offer all the children of the & nbsp; village squares in the & nbsp; kindergarten & raquo ;.
In & nbsp; this year, mother of many children Tatiana & nbsp; K. of & nbsp; Petropavlovsk-Kamchatsky (Kamchatka Territory) turned to the center for the employment of & nbsp; looking for a suitable job. Since at the time of filing the application, the citizen was not working, she was registered as unemployed and volunteered for vocational guidance. It turned out that the woman is fond of confectionery, has a penchant for entrepreneurship and would like to start her own business. According to the management of Pôle emploi, a mother of many children was trained as part of the national project “ Demography '' as part of the “ Entrepreneurship '' program. After completing the training, the specialists from Pôle emploi conducted several consultations with the citizen and helped draw up a business plan for the opening of a mini-confectionery. In & nbsp; October, a mother with many children successfully defended her business plan at a & nbsp; meeting of the Center Commission for Employment and & nbsp; received a one-time financial aid, which she will spend on & nbsp; buy material for his pastry.
Head of the New Diseases and Zoonoses Unit of the World Health Organization Maria Van Kerkhove told the Financial Times about the strain of the coronavirus omicron.
“ According to one of the hypotheses considered, it could come from an infected, immunocompromised patient who could not fully recover from the virus and in whose body the virus got ; is multiplied for a considerable time, & # 39; & # 39; & mdash; writing edition.
Kerkhove urged not to forget the changes that exist in the fight against the pandemic. & nbsp;
“ Strain delta & # 39; & # 39; has gone nowhere, people all over the world are dying of it. We must not forget how many people are infected with it, 'she urged.
Previously, the WHO & nbsp; classified & nbsp; a new variant of the coronavirus B.1.1.529 as being of concern. Due to the spread of the strain, Russia has decided to restrict entry from South African countries since November 28. The same decision has been taken by some other states. & Nbsp;
On November 27, Germany and the Czech Republic reported & nbsp; probable detection of cases of infection with the omicron strain. & Nbsp; Also in the Netherlands, dozens of passengers infected with the coronavirus from South Africa have been identified. & nbsp;
