3.7. When installing sleeves in a test tube holder, it is necessary to ensure that the difference in masses of diametrically opposite sleeves filled with centrifuged material should not exceed 2 g.

3.8. When using glass test tubes, the latter must be installed in sleeves of the appropriate shape.

3.9. If a malfunction is detected in the operation of the centrifuge, stop it, inform the master.

Turn on the centrifuge, after troubleshooting, only in the presence of a master and a locksmith.

3.10. It is forbidden to disturb the operation of the centrifuge lock.

3.11. Do not centrifuge with the cover removed.

3.12. Perform cleaning, washing, centrifuges only when the equipment is completely stopped and the electric current is turned off.

3.13. Keep the workplace clean, clean up spilled liquids in a timely manner, and eliminate the slipperiness of the floor.

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. ... >>

Data is transmitted at the time of the handshake 27.12.2002

The Japanese company "NTT DoCoMo" has developed a system that allows you to transfer data at speeds up to 10 Mbps between two portable computers at the moment when their owners shake hands.

The operation of this system, which, unlike wireless data transmission technologies, is much better protected from unauthorized retrieval of information, is possible due to the fact that human skin has relatively good conductivity.

Another possible application of the novelty could be its use for automatic identification of a person, for example, when touching a doorknob or a computer keyboard.

It is not necessary for personnel working on the centrifuge to know how to troubleshoot, as they are not allowed to repair or troubleshoot themselves. Throughout the text, the centrifuge is called either equipment or installation, it is necessary to decide on the terminology. According to clause 2.2, it is not clear how to check the serviceability of the grounding, for this you need at least to measure its resistance or establish that there is a break.
