From whom were the Americans forced to redeem the weapons donated by them four times more expensive than their cost?

After the entry of Soviet troops into Afghanistan, the Americans gave the Mujahideen, according to various estimates, from 500 to 2000 Stinger portable anti-aircraft missile systems. And after the Soviet troops withdrew from there, the American government began to buy rockets at $183 apiece. In this case, the usual cost of the stinger is 38 thousand dollars.

Authors: Jimmy Wales, Larry Sanger

What brand of car gave the name to the whole war?

In 1986-1987, a military conflict broke out between Chad and Libya for the right to control a narrow strip on the border of these states. The troops of Chad were much less technically equipped, but won the final victory. One of the decisive success factors was the delivery to Chad from France of 400 Toyota SUVs equipped with machine guns and anti-tank missile systems. Under the name Toyota War, this conflict went down in history - this is the only war that received its name from the brand of cars.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Social media and depression 02.04.2016

Social networks help us to meet new people, communicate, develop, etc. But everything has a dark side, and there are already a number of psychological works, the results of which indicate the not so good influence of Facebook, Twitter, Google+, Snapchat and other similar services on the psyche. So far, however, the results of such studies have been mixed, both because of the small number of statistics and because their authors have focused on a single network platform.

Psychologists from the University of Pittsburgh tried to address both of these objections: their statistics cover data on the psychological state of almost 1 people aged 800 to 19 who used the 32 most popular social Internet services (the aforementioned Facebook, Twitter, Google+, Snapchat plus Reddit, Tumblr , Pinterest, Instagram, Vine and LinkedIn).

On average, each survey participant spent 61 minutes a day on them, logging into their accounts 30 times a week. But this is an average, and after all, someone spends more time on the Internet, someone less. Here again, network activity was compared with the level of depression, and it turned out, as they say in an article in Depression and Anxiety, that the more often a person went to social networks and the longer he sat in them, the more depressed he was.

Thus, if assessed by the frequency of visits, then those who visited the social network site most often felt psychologically 2,7 times worse than those who visited the social network less often than others. And if you evaluate by the time spent on Facebook, Twitter, etc., then here some "users" differed in depression from others by 1,7 times. Of course, these figures were obtained, as they say, ceteris paribus, that is, the researchers also took into account the influence of other factors that could stimulate depression, from age and gender to income level and living conditions.

Can we conclude from this that social networks provoke depression? Not quite - the authors of the work themselves clarify that in this case we are dealing with a purely correlative pattern, and what is the cause and what is the consequence is not yet clear. It may well be that just a person with increased anxiety, consumed by sadness and longing, rushes to the social network in the hope of alleviating, so to speak, mental suffering.

On the other hand, it is not difficult to imagine how exactly Twitter or Facebook can spoil the mood. Firstly, they make us think about someone else's wonderful life - looking at happy photos and reading other people's happy posts, we sooner or later think about what kind of losers we are; secondly, this feeling of wasted time; thirdly, it is scolding, quarrels and scandals, for which the Internet is so rich.
