What are the benefits of snow?

We all know that a large amount of snowfall can disrupt a community. But snow can also be beneficial, especially for cereals. For grain to grow, water is needed. Where does the water that flows in streams come from? What do you know about water in the earth?

It is now known that all water (with the exception of a small part) comes with rain and melting snow. It seeps through the surface of the earth and fills rivers and streams. Water is always in the air in the form of an invisible gas - water vapor. Under favorable conditions, this vapor condenses into small water droplets or ice crystals, which turn into clouds and then into rain or snow.

In many parts of the world, rain is the main form of precipitation and therefore the main source of water. But in cold zones and at altitudes, the main form of precipitation is snow. In fact, the snow that accumulates in mountains near dry regions can form a natural reservoir of water far larger than any man-made. When this snow melts in spring and early summer, it turns into irrigation water.

In some areas, only this melting snow ensures the growth of cereals. Snow surveys are being conducted in the mountains of the western United States to determine how much water crops will need during the dry season.

How did laundries originate?

Wherever a person lives, he always had to solve the problem of washing. The word "laundry" has a curious origin. In the old days, washed things were shifted with lavender. This plant gave clothes a fragrant smell. The French word "lavande" is translated as lavender, and the word "lavandiere" is translated as laundress. So called in the old days in France a woman who washed clothes. This is where the words "laundress" ("laundress") and "laundry" ("laundry") came from in English.

Early civilizations used different ways of washing garments. In an ancient Egyptian tomb, there is a drawing showing two slaves processing wet clothes on an inclined table with a stone suspended from a block. Water flows down the gutter located under the table. The clothes of the Romans were made mainly of wool, and great skill was required in order to maintain their size and shape when washed.

The clothes were taken to public laundries, where they were processed by people who were called "fullers". The feller performed two types of work. He wove new clothes and also cleaned the ones that were brought to him. Felters practiced their craft for many centuries, until a fulling shop was established in England. By this time, wooden rollers were used for washing. Washerwomen used these rollers to hit wet clothes and thus remove dirt from it along with water.

In earlier times, when there were no rollers, clothes were trampled underfoot. For centuries, British laundries have used methods of washing clothes much like those used in ancient Greece and Rome. Clothes were washed without soap, as it was very expensive. Gradually, with the development of technology, washing clothes began to be carried out by machines.

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 ... >>
