For whose self-defense was a laser pistol created in the USSR in 1984?

In 1984, a non-lethal laser pistol was developed in the USSR. It was intended for the self-defense of astronauts. The damaging effect of this pistol was to disable the sensitive elements of optical systems, including the human eye. And an important advantage over a conventional pistol in zero gravity was the lack of recoil. Now the laser pistol is a monument of science and technology and is on display at the Museum of the History of the Military Academy of the Strategic Missile Forces named after Peter the Great.

Why do children get chickenpox?

Chickenpox (chickenpox) is considered a childhood disease, but adults can get it too. This disease is so rare among adults because, having been ill with it once, a person usually acquires immunity against it. Therefore, having suffered chickenpox in childhood, a person becomes immune to it. Chickenpox is a contagious disease. It is believed to be caused by a virus. Usually it is transmitted through direct contact with the sick person, and not through contact with his clothes and other things.

An infected person is considered contagious for about 14 days. That is why doctors require that the patient is isolated from other family members who have not had chickenpox before, and especially from young children. Also, he should not appear either at school or in other public places. Therefore, it is very important to detect this disease in a timely manner. Its symptoms are a slight fever, loss of appetite, headache and pain in the sides. But sometimes a rash appears first on the body.

You need to know that an infected person can infect another even two days before the rash appears. And so it happens that a whole group of children in contact with him fall ill before measures are taken to prevent the spread of infection.

Although chickenpox usually goes away quite easily and does not require special treatment, it is very important that the doctor makes a diagnosis in time and observes the patient: this disease is dangerous with complications.

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 ... >>

64-layer 3D NAND 512Gb chips 07.02.2017

Western Digital has announced the start of pilot production of 64-layer 3D NAND memory microchips (BICS3) with a capacity of 512 Gbps. These are the first products of this type in the world. The chips are made using TLC technology - three bits of information in one cell. Toshiba specialists took part in the development of the solution.

The microchips are manufactured at a facility in Yokkaichi, a special city in southeastern Japan that belongs to Mie Prefecture. It is here that Toshiba and SanDisk semiconductor chip factories are located.

Mass production of 64-layer 3D NAND chips with a capacity of 512 Gbit Western Digital plans to organize in the second half of this year. The company first announced the introduction of technology for the production of 64-layer 3D NAND chips in the middle of last year. And in 2015, the company demonstrated 48-layer 3D NAND products.

At the end of last year, Western Digital revealed some details about its plans for the use and production of 3D NAND flash memory based on the BICS architecture. Western Digital is taking a cautious approach to using XNUMXD NAND and in the near future plans to use this type of memory only for various types of removable drives - SD cards, USB sticks, etc.

It is noteworthy that Toshiba, which promotes Western Digital in the field of NAND production, also did not announce a single SSD based on 3D NAND (except for a rather exotic SSD in a BGA package), and its close partner, Lite-On Technology (an SSD branded Plextor ), did not showcase its Toshiba 3D NAND drives.
