How to convert a black and white TV to color mode?

In 1962, there was only one TV channel in Sweden that broadcast in black and white. On April 1, the channel's technical expert told viewers that thanks to the new technology, they can easily switch to color mode. To do this, a nylon stocking had to be put on the TV, which he demonstrated live.

What do people get allergies from?

What is an allergy? This is a pathological condition of the body in which a person has an increased sensitivity or generally an unusual reaction to a substance or some other physical factor. Many phenomena fit this definition, and the range of manifestation of allergies is very wide.

People can develop allergies to different kinds of food, medicines, dust, pollen, different kinds of matter, animals, heat, sunlight, and many other things. External manifestations (symptoms) of allergies can also be very diverse. But most often, skin and mucous membranes suffer from allergies. And it develops due to changes occurring in the cells of the body. If something foreign enters the tissues of the body, the body usually tries to fight it by producing substances called antibodies. They connect with foreign inclusions and neutralize them.

But when these inclusions enter the body a second time, the antibodies that have connected with the cells of the body break away from them to fight off irritants. This releases a chemical called histamine, and when that histamine reaches the skin or mucous membranes, it damages them, causing problems in the body that are symptoms of an allergy.

Not all the facts related to allergies have been explained by scientists, but it is believed that in some cases allergies can be inherited. Certain weaknesses in the structure and functioning of the organs of the body can serve as the basis for the development of allergies. The adrenal gland is also thought to be involved in some way, making some people more prone to allergies than others. And it is also believed that even mental states play a role in the development of allergies in some people.

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 ... >>

Comet dust in Antarctica 18.11.2010

Employees of the Franco-Italian scientific Antarctic station "Concordia" found microscopic particles less than a millimeter in diameter in a clean layer of snow at a depth of four meters.

The total weight of the collected particles is about one milligram. At 50-80% they consist of carbonaceous material - highly modified organic matter. They contain deuterium, and the ratio of its amount to ordinary hydrogen is ten times higher than in terrestrial water.

Scientists suggest that this is the dust of some kind of comet - a sample of the material from which the solar system arose. The dust fell on the pristine Antarctic snow as the Earth passed through the comet's tail.
