3.7. For short breaks in work, the soldering iron, which is in working condition, must be placed on a special stand. For long breaks, the soldering iron must be disconnected from the mains. Excess solder can only be removed on a special stand.

3.8. When building block equipment, it is allowed to remove the blocks, attach them with extension hoses and connect portable measuring instruments to them only when the power supply is turned off.

Extension hoses must have male and female connectors, designed so that after they are connected, there is no possibility of touching open live parts.

3.9. Screwdrivers must be selected so that their working part corresponds to the diameter of the screw and the width of the slot.

3.10. Wrenches must strictly match the dimensions of the nuts and bolts.

3.11. Stepladders must be used to work at heights. The use of metal ladders is prohibited.

3.12. Care must be taken when working with electrovacuum devices. When replacing and moving powerful lamps, it is necessary to protect your eyes with goggles and use cotton gloves (in case the lamps have not cooled to room temperature).

4. Labor protection requirements at the end of work

4.1. The workplace needs to be cleared.

4.2. The manufacturer, after completion of the work, must hand over the workplace to the admitting one. The delivery is made out in the journal of inspection and prevention.

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. ... >>

The world's oceans accumulate mercury and release it into the atmosphere 02.04.2023

A new study has shown that excess mercury enters the atmosphere from the oceans. The estimate of the amount of mercury in the atmosphere has been increased by 40%. Almost all mercury in nature is found in a bound form - in cinnabar. And for the dispersion of this toxic substance is mainly responsible for human activity.

A group of environmental scientists working at several institutes in China and the United States, as well as one in Belgium, found that the excess amount of mercury released into the atmosphere in the global circulation comes from the oceans.

Mercury is a heavy, silvery-white metal that exists in a liquid state at room temperature. It is clear that it is found in the environment and in most plants and animals. In nature, mercury is commonly found in cinnabar deposits. Thus, most of the mercury found in the environment is the result of human activities.

Higher than normal levels of mercury in the body can lead to a range of health conditions, including anxiety, irritability, and depression. Previous research has shown that the most common form of mercury poisoning comes from eating seafood.

The new model showed estimated levels of mercury around the globe and in the atmosphere. The researchers compared their results with other reference models and found a significant difference. According to their model, 40% more mercury enters the atmosphere every year than is noted in the reference models. The difference, in their opinion, was the amount of mercury in the oceans. The new model showed higher levels of mercury in the oceans than previously thought and higher emissions to the atmosphere.

The team suggests that higher levels of mercury in the atmosphere almost certainly lead to more mercury in the environment, which could put people at risk.
