Why did they change the names of astronauts from friendly countries?

The names of the cosmonauts, which seemed dissonant to the Soviet authorities, were changed. The Bulgarian Kakalov had to become Ivanov, and the Pole Hermashevsky - Germashevsky. The understudy of the Mongolian cosmonaut Zhugderdemidiin Gurragcha initially bore the surname Ganhuyag, but at the insistence of the Soviet side he changed it to Ganzorig.

Why is the lion called the king of beasts?

The lion has always been considered the personification of strength. We often say: "strong as a lion" or "lion's heart". In royal courts around the world, the lion was used on shields and banners as a symbol of power.

Perhaps this happened not because the lion can defeat any animal, but because he inspired fear and horror in people and animals.

The ancient Egyptians considered the lion a sacred animal, and at the time Jesus Christ was born, the lion lived in many parts of Europe. But by the year 500, however, they were all exterminated. Now lions are found only in Africa and parts of India.

The lion belongs to the cat family. The average length of an adult animal is about 3 meters, and the weight is from 180 to 225 kilograms. Males are larger than females. Hunters say they track the male or female by the size of their tracks. The male has larger forelegs than the female.

The lion makes a roar or growl. Unlike other cats, he does not purr and rarely climbs trees, is not afraid of water.

Lions prey on grazing animals, so they live in more or less open spaces, and not in forests. And since lions must drink at least once a day, they usually live close to bodies of water.

The lion sleeps during the day and hunts at night. He can live alone, or in a pair, or in a group of four to ten individuals. Lions mainly feed on zebras, gazelles and antelopes. Sometimes they attack giraffes, but never touch elephants, rhinos and hippos. When a lion is not hungry, he does not pay attention to other animals.

During the hunt, the lion can sit in ambush or crawl up to the victim, and then make a sudden jump. During this throw, he develops a speed of up to 64 km / h!

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 ... >>

Solar tower lights up Las Vegas 15.02.2012

SolarReserve has completed major work on a solar power project near Las Vegas. This power plant will use molten salt to store energy stored during the day and transfer it to the city at nightfall.

The project is called the Crescent Dunes Solar Energy Project. The station itself is a tower about 165 m high. According to the creators, this power plant will be able to produce up to 110 MW of electricity by the end of 2013. The storage capacity will provide full power for 10 hours. Thus, the Crescent Dunes Solar Energy Project can become a full-fledged permanent source of electricity, capable of supplying part of Las Vegas.

The SolarReserve project differs from similar ones in that only one energy carrier is used here - molten salt at a temperature of about 1000 ° C. At the same time, salt is stored in a special tank at a temperature of about 500 ° C. After that, part of it is delivered to a special compartment, where it is heated and melts. Next, the melt enters another tank, from where it goes to a heat exchanger to generate energy.

In the summer, the company plans to install 10 mirrors around the tower, each of which is several square meters in area. These mirrors will reflect sunlight and direct it to a special receiver measuring more than 30 m. The mirrors will be located at a distance of more than 3 km around the tower.
