screen surface - 300 lux;
manuscript - 400 lux;
keyboard - 400 lx.

3.5. The local light source in relation to the workplace should be located in such a way as to exclude direct light from entering the eyes, and should provide uniform illumination on the surface of 40 x 40 cm, not create blinding glare on the keyboard and other parts of the remote control, as well as on the screen of the video terminal in direction of the operator's eyes.

3.6. For protection against electromagnetic radiation, special screen filters must be used.

3.7. When periodically monitoring the screen: the screen should be on the right, the keyboard against the right shoulder, and the documents in the center of the left viewing angle. During continuous operation, the screen should be located in the center of the field of view, documents on the left on the table or on a special stand. The manuscript, keyboard and screen should be at the same distance from the eyes of the worker.

3.8. To reduce visual and general fatigue after every 1 - 1,5 hours of work behind the screen, regulated breaks should be used, during which passive rest is carried out. The distribution of breaks in the first and second half of the work shift can be as follows: 3 breaks of 5 minutes each. before lunch and 3 breaks of 10 min. after lunch.

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. ... >>

Catapult-railgun for fighters 07.08.2017

The US Navy has tested the Gerald R. Ford-class aircraft carrier, as well as a new system of electromagnetic catapults for launching fighters installed on board.

Previously, the catapults used to accelerate fighter jets and launch them from a short aircraft carrier runway were powered by steam, with the only viable alternative being a linear runway. Traditional catapults used steam from the ship's nuclear reactor, which created the necessary pressure - since the Second World War, this technology has changed only slightly, the general principle has remained the same.

Such a system has a number of disadvantages, which include the need for frequent checks of the steam supply mechanism and the limited power of the system itself. In addition, it is simply not suitable for modern air forces: if fighters can still be launched using steam catapults, then certain difficulties arise with light, compact UAVs.

EMAILS is powered directly from the ship's generator. She accelerates the fighters with the help of electromagnets, pushing them into the air at great speed.
