1.2. Radio measuring work on PPC equipment can refer to work performed both without removing voltage away from current-carrying parts that are under voltage (checking the presence of mains voltage using stationary devices, channel quality control, channel measurements, etc. work), and with voltage removal (measuring the parameters of antenna-waveguide paths, devices for separating and combining microwave signals, etc.). A list of works with stress relief, without voltage relief on current-carrying parts and near them, without voltage relief away from live live parts, must be drawn up at each enterprise by its chief engineer and agreed with the elected trade union bodies.

1.3. Radio measuring work on RRS equipment can refer to work performed both in the order of current operation (carrying out regular routine measurements), by order (measuring the quality indicators of shafts or channels) or along side (measuring the parameters of the antenna-feeder path).

1.4. Employees who carry out radio measuring work on PPC equipment are required to comply with and comply with the internal regulations established at the enterprise, i.e. observe the time of the beginning and end of work, breaks during the working day for rest and meals.

1.5. Radio-measuring work on the RRS equipment can be carried out by personnel carrying out operational and technical maintenance of the RRS, personnel of the emergency and preventive service and seconded to carry out specialized radio-measuring work.

1.6. In the premises where the RPC equipment is located, the following dangerous and harmful production factors are typical and present:

dangerous voltage levels in electrical circuits, the closure of which can occur through the human body;
increased level of electromagnetic radiation of very high (VHF) or ultra-high (UHF) frequencies;
increased noise level in the workplace;
increased air temperature in the workplace;
other factors determined by the geographical location of the RRS (desert, tundra, regions of the Far North, high mountains, etc.), its design (ordinary room, container version, recessed or located in a cabin on a tower, etc.).

1.7. Employees performing radio-measuring work on RPC equipment must be provided with special clothing, special footwear and other personal protective equipment in accordance with applicable regulations and are responsible for their correct application, use and preservation.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Thermal power plant on vegetable oil 08.01.2005

The Anglo-Belgian concern, with the participation of the German company Siemens, has commissioned a thermal power plant in the city of Bregenz (Austria), in the furnaces of which waste edible oil is burned, which remains after frying donuts, potato chips, popcorn and other products in fast food establishments.

The power of the station, which consists of three blocks, is 3,4 megawatts. Excess heat is used to heat the neighboring quarters of the city. Since edible oil contains virtually no sulfur, the smoke from burning it is not as harmful as from burning fossil fuels.

However, the cleaning filters installed at the CHPP ensure the elimination of nitrogen oxides and the appetizing smell of fried food, which, in too large doses, can cause dissatisfaction among the townspeople.
