Why is it good to sleep in the middle of the day?

Currently, physiologists believe that a person should sleep not once, but at least twice a day. They have proven that a short nap in the middle of the day improves concentration and productivity.

So, for example, the speed of visual reaction (the time during which a person understands what is written on a computer screen) in the morning is 10 milliseconds, in the evening - 40. But if the subject slept during the day, then in the evening he perceives information as quickly as in the morning.

In favor of the expediency of daytime sleep, the fact that a person’s temperature during the day is not constant, but has two minimums - in the intervals of 3-5 and 13-15 hours. It is at this time that most people have the strongest desire to sleep.

This pattern is explained by the fact that our primate ancestors, inhabitants of hot tropical countries, were mainly crepuscular animals; they were especially active at dusk, in the evening and early in the morning. And in the middle of the day, during the hottest time, they sleep under the shade of dense crowns.

First in Japan, then in Europe, and now in the United States, many firms have begun introducing daytime naps. In the German town of Vechta near Hamburg, municipality employees can get 20 minutes of sleep a day if they wish. In order not to hire additional employees, the mayor's office decided in this way to increase the efficiency of the existing employees.

What is peat?

Peat is not coal. It can be called a stage in the process of obtaining coal. Coal is the remains of ancient trees and plants that grew in swampy jungles, in a warm, humid climate hundreds of millions of years ago. These trees and plants eventually got into the swamp water. During the decomposition of wood by bacteria, gases were produced that escaped, and a black mixture was formed, the main part of which was carbon. Over time, under the pressure of mud and sand, the liquid leaves the mixture, and the viscous mass hardens, turning into coal. This process, from start to finish, spans thousands of years. But the first stages of the coal formation process can be seen even now.

Peat forms in the Great Dismal Swamp in Virginia and North Carolina and in thousands of swamps in the northern states of the United States and Canada. In these swamps, plants are in the process of decomposition, releasing large amounts of carbon. After several years of this process, a brown mixed mass of twigs, branches and leaves is formed. This is peat. When water is pumped out of such a swamp, the peat can be cut into pieces, laid out to dry, and burned. Drying is necessary, since peat in the soil is 3/4 water.

In Ireland, where peat is plentiful and coal expensive, more than half of the farmers use peat for fuel. Other types of coal are derivatives of peat. If peat is left where it was formed, it gradually turns into lignite, or brown coal. It is harder than peat, but still quite soft and crumbles when transported over long distances.

The next type of coal is bituminous, or soft coal. It is formed in the earth from lignite through chemical changes and under pressure over thousands of years. It is the most important member of the coal family. It burns easily and is found in large quantities. If bituminous coal is in the ground and subjected to sufficient pressure, it gradually turns into hard coal, or anthracite. It burns almost without smoke and lasts longer than bituminous coal.

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 ... >>
