an ak-47 assault rifle was found in the bushes. the trump campaign released a statement confirming that former president trump is safe, and it is reported that a suspect has been detained. the golf course itself is located just five miles from the maralaga residence in palm beach, where former president trump and the candidate spend their time playing golf, in their free time from the campaign. now the approaches to this area are completely blocked. well, it is worth mentioning, of course, that this happened almost exactly 2 months after he was shot in the ear, trump was shot in the ear, as was the shooting during the assassination attempt on the rallies in butler, pennsylvania on july 13. that's all the details for now. yes, thank you dmitry, but we still need to wait for the results of the investigation to be clear that it was from the united states. our own correspondent, dmitry melnikov, was on the line with the studio.

science and sports have long gone hand in hand. it was in this tandem that the first electronic scoreboards, ultra-precise stopwatches, special polymer fabrics and much more. you may ask, but what does science have to do with it if i'm on a football pitch right now ? you'll learn about this and more in the new episode of our program. how can rice husk be turned into the material of the future? our very first studies showed that. the coal obtained from

restaurant husk has great potential. is it possible to improve aviation fuel with the help of regular fat? fatty acids themselves are a hydrocarbon chain with oxygen at the end, so that we can turn this chain into a chain kerosene, we need to remove oxygen, and what attracts students from moscow to komsomolsk-on -amur? after receiving my diploma, i will go to the far east, where i will show what i have learned during my studies. there is good career growth, there are good conditions, from the point of view of a fan, it is not difficult to prepare a football pitch for a match, water it on time and mow it, but behind this there is a complex system of knowledge from various fields of science. science for sports is really a separate field of knowledge, and really a lot of developments are useful, yes, namely sporting achievements, but still, here is football and a football field, where is the science here? here

everywhere, in fact, natalia, here is an interweaving of many sciences, at least, this is agronomy, biology, this is also a technical component, the science of mechanization of production, plus - this is a large engineering complex, in which a huge number of different life-support systems of the lawn are tied, from the heating system to the irrigation system, each lawn is prepared completely differently, according to its characteristics, a football field, the main ... wear criterion, stability. well of course, when athletes run around the football field in their boots, it must apparently withstand such loads, plus from a medical point of view, you see, we have already remembered about medicine, yes, another science from a medical point of view, the lawn must meet the requirements of cushioning, that is , so that there are fewer injuries. but now we are standing on the edge of the football field and they told me that i cannot go deep, why? yesterday we treated the football field, after a series of matches, we needed to carry out sanitary treatment, this is a normal story.

football pitch must be aged for 48 hours before a human foot steps on it. a football pitch is like a large living organism that requires constant care. multicomponent mixtures are used for its treatment, which contain stimulants to strengthen the root system, a grass growth stimulant, as well as substances that protect against fungal diseases, and the grass itself is the result of the interaction of selective genetics and new technologies. vladislav, this is the first time i've seen a greenhouse in which nothing grows except grass, why do you need grass in grow in a greenhouse? this is our kind of nursery, which can be used all year round, as a donor site, from here you can replace something, yes a patch, if some force majeure happens on our fields, we can cut out any fragment from here and simply replace it on another field. and in general, is the grass all natural or are there still some artificial impurities, well, so that after all yes wear resistance was greater, right?

the arena uses a hybrid stabilization system, this is how the fibers are sewn, embedded in natural grass, artificial, and what is polypropylene made of, polypropylene reinforces the lawn. protects it from flat ones like a frame like this, yes it turns out , a football field begins with a fifteen-centimeter crushed stone cushion with stones from 20 to 40 mm in size, then smaller crushed stone from 5 to 20 mm, then granite screenings of a very small fraction, these layers perform the drainage function, then there are two layers of sand, between which there is a geogrid, to which the field heating pipes are attached, the last 10. layer in which the grass grows, and polypropylene threads sewn into natural sandstone with peat - this is fertile grass, intertwine go deep, significantly increasing wear resistance, and to maintain it in perfect condition, another science comes into play, as i understand it, this is a portable

weather station, what is it for? yes, that's right, this is what we will just turn to another science , agrometeorology, that is, the direction of the wind speed, a reservoir for collecting the atmosphere. precipitation, which gives us an idea of ​​how much rain has fallen, say, over a certain period of time, in order to correctly calculate the irrigation dose. speed wind also helps to collect analytical information about the air exchange in the stadium bowl, if this is not enough, we turn on forced air circulation, these are fans in our two shaded areas. there are no trifles in creating an ideal lawn. uniform ventilation of the lawn is necessary so that it does not turn sour and does not appear on it. and if some part of the field is in the shade because of the stands, then it is additionally illuminated with a special mobile system of lamps. but the most difficult thing is to properly prepare the lawn for the match in any weather. yes, this is manual work, the match lasts 90 minutes, preparation for it usually lasts 5 hours, recovery activities

are carried out for 48. exhausting preparation, because the match will take place in almost any weather conditions, like last year's match with zenit, when the entire field was covered. it, we prepared for it specifically, just thanks to the meteorological station, we received the collection of information that allowed us to cover the field with material in time and clean it during the match. thanks to such preparation, the match at the rzhd arena still took place, although at the same time games in warmer european countries were cancelled. engineering helps to maintain the ideal condition of the field in any weather, complex irrigation and heating systems are hidden from the viewer's eyes under the field, this is 45 km of pipes, and there is also a technical innovation that only a few arenas in russia can boast of. now we are under the football field, there is a drainage system, a kind of pulmonary system of the football field, which in the required amount supplies air to the root zone and at the same time

is able to pump out excess moisture from the kidney profile, allowing you to maintain an optimal water-air regime. football turf, as a symbiosis of science and art, it is difficult. goredka, where i met, and this is probably one of those things that help, yes, the locomotive to achieve results, the work of a large number of people does not go in vain,

the arena's field is considered the best in the country, while i will make my aesthetic contribution, trim the grass a little, you will find out what is true and what is not, in myths about football. hello! myth number one: in football, the main thing is physical ability, not intelligence. i knew many football players who were gifted physically, but were, let's say, not very intellectually savvy, and there are, on the contrary, football players who play due to their intellect, not gifted with physical qualities, so most likely this is a myth. myth on...

some medical things, they help football players to be in optimal shape, so this is a myth. myth number three: all football players are superstitious. it's true, i think all football players are superstitious, this is not a myth. superstition at each one is different, i can say. let's say the coach doesn't like it when the bus backs up, someone. directly on the field, and a woman is not allowed on the bus, there are also such, myth number four: the place in the tournament table directly depends on the team's budget, this is a myth, because there are teams with small budgets, but the club has the right structure, then it turns out that we see teams like, let's say, rostov, which... did not become champion, played in the champions league, so this is a myth. myth number five:

professional football is harmful to health. this is not a myth, i think that many people understand that these are injuries, these are certain chronic illnesses and even concussions, it is still harmful to health. this is not a myth. myth number six. girls do not love football, but football players. this is a myth. i know a lot of football families, wives, girls, they... go to watch their husbands, watch on tv, love the atmosphere, some even like to watch other matches in bars of a certain nature, let's say, this is a myth, next in our program is a scientific dish from rice husks, and what replacement for jet fuel russian scientists have found, sustainable aviation fuel can be... obtained from a wide range of waste that would otherwise either decompose in landfills or

be incinerated, everything is for the benefit, any housewife knows what can be made from rice, here's how to use the remaining husks, only scientists will figure it out, we take the original rice husks, accordingly place it in a porcelain cup, then we need to peralize it, we accordingly... put it in the oven, oven not simple, you can't cook rice porridge in it, because the pyrolysis process is the thermal decomposition of organic compounds with a lack of oxygen, this is the only way to burn rice husks, under normal conditions it just smolders, but does not burn, we already have a slag , and then we ... chemically separate this ash into two main components: coal and

silicon dioxide, then we study the coal, that is, chemically, various physical, what attracted the attention of scientists to ordinary coal? but the point is that after the pyrolysis of rice husks, it turns out to be quite unusual. coal, which is formed from ash, rice husks, it has a very high specific surface area, such high indicators, they are typical for ... and coals that have undergone special chemical treatment, here we practically in one step get very good coal with great potential for use in industry. one of the most famous ways of using coal is adsorption, that is, the absorption of substances by its surface, for example, coal in water filters has surface area of ​​about 200 km per gram, in activated carbon from the pharmacy already 500-600, however, if the number is higher, then such material ... can already be used for industrial cleaning from any particularly harmful substances or for obtaining

energy sources, we prepare a paste from coal, apply it to electrodes, assemble and get the well -known small batteries, which can be tested, well, and visually you can simply light a light bulb from them. due to the porous structure, rice husks give a unique coal with a very large surface area. then scientists constantly study the material, achieving. improved characteristics, we put it in a cell, start the device, and for about a day the device is busy with independent measurements, after that we get all the information about the surface area, about the porous structure, about how everything works here, as a result of research scientists literally adjust the surface of the coal for their needs, with the help of chemical or physical processes they can... increase the surface area several times more. in this way, we improve the interaction in

electrostatic and thereby increase the capacity of our supercapacitors, batteries , etc., that is, sources for storing electrical energy. and this is not the only useful application of products obtained from processing rice husks. the hall also contains silica, which, unlike natural silica, is easily processed. it is found in plastics, food fillers, toothpastes, tablets and much more. we are very glad that our undertaking is not over in some laboratory studies, and has already moved to the level of fairly large-scale production, this is simply our. first project, which is advanced not only in the country, but advanced throughout the world. contrary to popular belief, airplane wings are needed not only to take off, under their aluminum skin are tanks with tens of tons of aviation

fuel, such gigantic volumes on the one hand made long-distance flights possible, and ... on the other hand, they became a problem for the environment, global warming is occurring, the growth air temperature on the earth's surface, this is due to the large amount of greenhouse gas emissions emitted by transport, including air transport. scientists were given the task of decarbonizing aviation, that is, making sure that the carbon footprint of fuel was zero, but for this, ideally , electricity or hydrogen would need to be used as an energy source, and such a transition would be very long and expensive. therefore. here, and an intermediate solution, and, which in fact can play a fairly long, is sustainable aviation fuel or saf. sustainable aviation fuel is produced from environmentally friendly raw materials, but in order to switch to mass use in the future, it is necessary to make sure that such raw materials are sufficiently inexpensive. here our scientists took as a basis fatty waste,

waste oils from restaurants, waste from wood processing and technical fats. from meat processing plants fats are a complex ester of fatty acids, fatty acids themselves are such a hydrocarbon chain, at the end of which there is also oxygen, in fact for in order for us to turn this chain into a kerosene chain, in kerosene it is just such an ordinary chain without an acid group at the end, we need to remove oxygen, for this purpose our own technology of multi-stage purification and processing was invented. the first stage is mechanical purification and filtration in order to remove particles that... get into the raw material together with fats. in the second stage, using the process of esterification or transesterification, the product is unified. various fatty acids and ethers are reduced to the same type of compounds, which allows processing different raw materials. the third step removes oxygen from the molecules of the unified raw material. the result is a chain of alkanes slightly longer than needed for the kerosene fraction.

with this reactor, we reduce the length. of the hydrocarbon chain of our molecules so that they correspond to the kerosene fraction and at the same time , isomerization of the chain into a more branched chain occurs in this reactor. with this system , we can pump gas into the reactor, control its pressure, also control the pressure in the reactor itself, monitor the temperature, the heating rate and how the temperature behaves during the process. also here the catalyst is placed now we will add our preliminary fraction in order to obtain kerosene. our scientists were the first in the world to implement such a universal technology for processing fatty waste into a high-quality component of jet fuel, and considering the amount of biological raw materials from the processing of forests or agricultural products - this is only beginning. the well-known refrain that first of all the planes, and then the girls, seems

to be finally becoming a thing of the past. more and more often , it is the girls who see their future in the development of aviation. our next heroine, for example, successfully studies at mai, although the matter is not limited to the university program. i was always told that a girl should not play sports, a girl should not do the exact sciences, should not wear short hair, there are many things that i should not, but i want to destroy all this. look at me. look what i have achieved, and guys, don't be shy to be yourself, my name is violeta goreeva, i am from nikiyugansk, i am a student at the moscow aviation institute, and i work at an experimental pilot plant, and i study, play sports, and also run a business, i really love doing the exact sciences, so the choice immediately fell on mine, and also i

, of course, dreamed that i ... work in some kind of aviation industry and for me it became a sign, i immediately looked at all the universities that were suitable, and i immediately fell in love with mine and applied here documents, i study in the direction of radio-electronic systems and control complex, i have all the spheres of my activity, they correlate with each other , interact, complement each other, that is, i do not invent something. i am trying to improve, create something that would help our residents, our society, our country, if the rest more. but to develop some one direction, then it is very important for me to develop everywhere constantly, and for it to bring its results, but i do not think that

every second student, of course, is like that, and this still, thanks to my parents for raising me, because they invested a lot in this, and i want to justify their hopes, expectations, my work plans have already been outlined, i signed a target contract with the komsomolsk -on-amur aviation plant named after gagarin. and after receiving my diploma, i will go to the far east, where i will show what i learned during my studies at the university, this is a good opportunity for such young students to realize themselves, there is good career growth, and there are good conditions, this is a springboard that will help you become the most in demand specialist in this field, i want to be there, in addition to working at the plant and moving up the career... ladder, and also opening my own martial arts school, opening a branch, and a hairdressing salon and developing the far

east in general, so that it would be like moscow. last year i studied at the abcs of an entrepreneur, we had a course for young entrepreneurs. then i collected documents, wrote a business plan, and applied for a grant. i received it. i spent 500,000 on developing a third salon. in nefteyugansk - this is the only chain of beauty and manicure salons that can boast such success. i have been into martial arts since childhood, and asked my mother to send me to sports. and at the age of 6, she brought me nado to the nefteghansk olympic reserve school. and when i entered mine, i knew that i needed to continue my sports career.

there are, but i treat them as experience, it seems to me that such a position is adult, competent, allows you to work on your mistakes, and not make them in the future, i want to be a competent specialist, i have probably been striving for this all my life, because it is very important for me to realize all my skills, to develop all... my competencies at the highest level, to show that there are such talents in russia. how to help

a young scientist achieve his goals, where students will live and what they will study in the near future, we will find out right now from the deputy minister of science and higher education of russia. andrey, i would like to know what a university campus is, why it is needed, what is the main ideology? first of all, it is important to understand that the project to create...

no matter how technologies change, all the same, if a person who graduated from the university has a strong basic core, it is always much easier for him to adapt, rebuild and gain competencies for a specific workplace, the task of higher education is to educate a specialist with certain knowledge, intelligence, the ability to learn and self-actualize. i absolutely agree, and so that the guys, again, who have the makings, yes, were realized not only for specific work. place, but also as startuppers, as innovators, as those who can create some new, absolutely, still unknown to the market product, that's why we

launched a big one. including in entrepreneurship, so the initiative today includes a whole large block of events related to the formation of this entrepreneurial culture. andrey, thank you very much, but i still have. there are still a lot of questions, so we will continue our conversation in the next issues, this was the science program and i, natalia popova, to meetings, until next time, of course.

so says the beacon.

we'll take on this case, it'll be an honest detective story. and we're back to the news from the us, as cnn claims. the secret service is inclined to believe that an assassination attempt could have been made on presidential candidate donald trump. according to cnn, the attacker shot at trump near a golf club in florida. secret service agents determined where the shooting was coming from and returned fire. the alleged perpetrator was able to escape, and a gun was found at the crime scene. a semi-automatic rifle and a magazine for it, as well as a gopro camera. it can be assumed that the suspect was trying to record the shooting at...

trump, when a suspicious person was noticed with an object similar to a firearm. let me remind you that almost 2 months ago, on july 13, trump was already shot during a campaign rally. the ex-president was wounded in the ear. i will note the candidate's campaign headquarters after today's shooting.
