3.15. If vibration occurs, stop the rotation of the tool. Take measures to eliminate vibration: check the fastening of the drill and the parts.

3.16. Stop the drilling process when:

• temporary cessation of work;
• interruption in the supply of electricity;
• cleaning, lubricating and cleaning the workplace and equipment;
• installation, measurement and removal of parts;
• checking or cleaning the cutting edge of the drill;
• technological maintenance of equipment and devices.

4. Labor protection requirements in emergency situations

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. ... >>

Random news from the Archive A new record for the duration of thermonuclear fusion 12.09.2022 An international group of researchers managed to keep thermonuclear fusion at a temperature of 100 million kelvins for 20 s. This is a new record. Previously, scientists have been able to either reach such a high temperature, or keep the plasma for a long time. For several decades, scientists have been trying to create stable thermonuclear reactions for electricity. Although these studies have made some progress, the main goal of creating a sustainable process still remains far off. The smallest deviations lead to instability that prevents the reaction from proceeding, the scientists explain. The biggest problem is related to the release of heat, which is measured in millions of degrees. No materials can hold such a hot plasma, so it levitates in a magnetic field. Two approaches are used to control plasma: edge and internal transport barrier. In the first case, an external magnetic field prevents the plasma from escaping, and in the second, a high-pressure region at the center of the plasma keeps it under control. In their experiment, physicists used it. The researchers note that the use of an internal transport barrier results in a denser plasma. This, in turn, makes it possible to achieve higher temperatures in the center. At the same time, the temperature is lower near the edges, which makes it possible to keep the plasma stable for a longer time. The scientists plan to refine their installation, taking into account the results obtained in the experiment, in order to develop a system that will work stably for even longer.
