4.3.48. Buildings of converting substations and premises of converting installations should be classified as category G production according to SNiP.

4.3.49. The walls of the converter rooms must be plastered and painted up to the ceiling with light oil paint, and the ceilings must be whitewashed. The rest of the premises are painted and finished in accordance with their purpose.

4.3.50. The floors of the converter rooms must have a dust-free coating (for example, cement with marble chips, metlakh tiles).

4.3.51. Mounting hatches or openings for transporting heavy and bulky equipment should be provided in the ceilings and walls of the premises. Hatches should be located in the area of action of the lifting device. The cover of the hatch must have the same degree of fire resistance as the ceiling of the room in which the hatch is located.

4.3.52. The basement of the premises must have waterproofing and a drainage device.

4.3.53. Cable tunnels entering the buildings of converting substations or premises of converting installations, at their junction with buildings (premises), must be separated from them by partitions with a fire resistance rating of 0,75 hours and doors with a fire resistance rating of at least 0,6 hours. Doors should open towards the substation (installation) room and have a self-locking lock that can be unlocked without a key from the side of the tunnel.

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 ... >>

Virtual reality cures fear of heights 17.07.2018

Fear of heights is one of the most common phobias in the world. And now a group of European researchers have found a new way to treat it that doesn't require going to the doctor or going up to the roof.

The researchers used 100 volunteers for the experiments, all of whom were previously diagnosed with a fear of heights, but they did not receive any treatment for their problem. The researchers then divided the volunteers into two groups. 51 volunteers were sent to the control group, while 49 people were given the opportunity to undergo a two-week virtual reality treatment (47 people agreed to the offer and 44 completed it). The scientists published the results of the study in The Lancet Psychiatry.

During the program, volunteers used a virtual reality helmet along with a "virtual trainer" for six sessions, each lasting approximately 30 minutes. The automated trainer asked them questions about their fear of heights and told them facts about their phobia. He then took the subjects through a series of virtual scenarios to help people address their fear. In the scenarios, people were in different situations: for example, they could throw a ball over a roof parapet or save a cat from a tree. At the end of each session, the trainer asked people how they were feeling and encouraged them to face their fear in the real world between sessions.

All participants filled out questionnaires about how intense their fear of heights was before the test, two weeks later (that is, shortly before the end of the virtual sessions), and two weeks after the experiment. By the end of the trial, 34 of the 49 volunteers said their fear was much less. In all participants in the control group, the level of fear remained unchanged.

This and other examples show that VR can help people with mental health problems. However, this is only the first trial to show that virtual reality treatment can produce the desired results without the help of a trained (and potentially expensive) therapist. According to the study's lead author, Daniel Freeman, the new technology could increase the number of people who receive the psychological help they need, not only for fear of heights, but also for other disorders. At least, the researchers themselves do not intend to dwell on acrophobia alone.
