Как move in the desert?

Once in the desert, a person is faced with excessively high air temperature, intense solar radiation, and strong winds. The body receives an extra 300 kcal / hour and quickly dehydrates. Therefore, the duration of movement in the desert is limited mainly by water reserves.

You can estimate the period of autonomous existence of a person in the desert, depending on the temperature and available water reserves, according to the following table.

Maximum daily temperature, °С	Water supply for 1 person per day
Maximum daily temperature, °С	0	1	2	4	10	20
Stay under the tent
49	2	2	2	2,5	3	4,5
43	3	3	3,5	4	5	7
38	5	5,5	6	7	9,5	13,5
32	7	8	9	10,5	15	23
27	9	10	11	13	19	29
16	10	11	12	14	21	32
10	10	11	12	17	21	32
Movement at night
49	1	2	2	2,5	3
43	2	2	2,5	3	3,5
38	6	3,5	3,5	4,5	5,5
32	5	5,5	5,5	6,5	8
27	7	7,5	8	9,5	11,5
21	7,5	8	9	10,5	13,5
16	8	8,5	9	11	14
10	8	8,5	9	12	14

Because 72% of the heat comes from solar radiation, an awning is needed to protect from the sun. All work should be carried out at night, during the day any physical activity is limited.

Do not take off your clothes, the wind dehydrates the body. The water loss of a naked person at a temperature of 35-50°C and a wind speed of 2.5 m/s is 500 grams per hour, and in clothes - 340 g/hour.

However, clothing must be ventilated. In desert areas, it is best to wear long pants with a long-sleeved shirt. Cover your neck from the sun with a piece of cloth. When choosing clothes, keep in mind that the nights in the desert are cold. Clothing should be loose enough to be tucked into gloves and socks. As in all cases, when choosing clothes, preference should be given to sets of clothes designed on the basis of the national clothes of local residents. Of course, only if it does not interfere with the performance of your official duties. Grazing sheep and flying on a hang glider is desirable after all in different clothes. You can only shoot it in the shade, as even reflected sunlight can cause a burn.

To prevent the eyes from the sun's rays, a tape 15-20 cm long should be made from the fabric and narrow holes should be cut in it for the eyes. You can fix the glasses on your face with rubber bands, and blacken the edges of the slots with soot.

The movement itself is usually not particularly difficult. Possible obstacles: sandstorms and quicksand. The latter, however, are very rare.

During the passage of a sandstorm, movement should be stopped. Try to build yourself the simplest shelter, simply dig into the sand. Close the head and airways with outer clothing as tightly as possible, breathe through the material. Breathing should be calm, only through the nose.

When entering the zone of quicksand, one should behave in much the same way as when entering a swamp. Try to lie on your back, free yourself from the burden, roll over on your stomach and crawl in the opposite direction, trying to occupy as much support as possible. Relying on your elbows or palms is strictly prohibited. Usually quicksands are found in groundwater outlets, on the banks of rivers, in the place of dried lakes. It is impossible to run across such revenges, tk. it can be even worse further on, even if the surface seems to be drier. Usually all the troubles happen because of your own stupidity, so it's better to first think "Maybe it's worth getting around, and not climbing ahead."

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 ... >>

artificial wood 23.05.2020

A new material developed by the University of Science and Technology of China, which is light in weight, as strong as wood, but does not have the standard weak characteristics of wood, does not burn or absorb water.

To create synthetic wood, we took a solution of polymer resin and added a little (a pinch) of chitosan powder, a basic cationic polysaccharide polymer obtained from crab and shrimp shells. They sublimated the solution, resulting in a structure filled with tiny pores and channels, backed by chitosan. They then heated the resin to a temperature of 200 degrees Celsius (to vulcanize the latter), thus creating strong chemical bonds.

Unlike real trees, the new material does not take years to grow. In addition, the new material practically does not absorb water; specimens immersed in water and a strong acid bath remained there for 30 days with little or no loss of quality, while specimens of Balsa wood tested under the same conditions lost two-thirds of their strength and 40 percent of their resistance to turmoil. The new material was practically incombustible and stopped burning as soon as it was removed from the flame.

Imitation wood could be used in the production of reliable resistant containers. And the porosity property of the new synthetic material seems to be important, since it acts as an air trap, which could make such a substance an excellent insulating material suitable for building construction.

Environmentally friendly alternatives to polymer resins could also increase interest in the new material.
