2. For types of labor activity, 3 categories of severity and intensity of work with a computer are established, which are determined: for group A - by the total number of characters read per shift (no more than 60000 characters per shift); for group B - by the total number of characters read or entered per shift (no more than 40000 characters per shift); for group B - according to the total time of direct work with a computer per shift (no more than 6 hours per shift).

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. ... >>

Smartphones can withstand 15 meter drops 20.07.2018

Corning's new generation of Gorilla Glass 6 is nearly twice as strong as current designs. The first smartphones, endowed with a new glass, should appear on the market in the coming months.

According to a Toluna survey, on average smartphone users drop their gadgets 7 times a year, with half of the cases falling from a height of about 1 meter. It is these statistics that Corning decided to use when introducing a new generation of its Gorilla Glass 6 protective glass.

The developer claims that with its protective glass, gadgets can withstand up to 15 drops from a meter height onto a hard surface. That is, you can safely drop your smartphone for at least 2 years. True, these are, of course, test results: in fact, everything depends not only on the height of the fall, but also on its angle and the nature of the surface. So with special luck, you can break the phone the first time. Smartphones endowed with the new Gorilla Glass 6 glass should appear on the market in the coming months.
