1.2. Persons at least 18 years of age who have undergone a medical examination, training, instruction in labor protection and have passed an exam with the assignment of a qualification category are allowed to work on semi-automatic machines for grinding springs.

1.3. Follow the instructions for labor protection - this will protect yourself and others from an accident.

1.4. Do only the work that is assigned to you by the master, and on the condition that you know the safe ways to do it.

1.5. Work on machines only of those systems that you have studied and for independent work on which you are admitted.

1.6. If you notice violations of labor protection rules by other workers, warn them about the need to comply with OT requirements.

1.7. Work only in serviceable, neatly tucked overalls and using serviceable protective devices provided for by the Model Industry Standards for this profession: a viscose-lavsan suit (robe), leather boots, goggles, a respirator.

1.8. Make sure that the floor around the machine is flat and non-slip, if it is doused with oil, emulsion, demand that it be sprinkled with sawdust or do it yourself. Then remove them from the floor with a shovel or shovel into a specially designed container for collecting industrial waste.

1.9. Do not work on equipment that is not working or where safety guards, interlocks, and grounding are missing or defective.

1.10. On the territory of the plant and in the workshops, follow these rules:

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. ... >>

Mystery of natural mushroom factory solved 01.05.2012

Researchers at the University of Bristol have unraveled the mystery of a mushroom 'natural factory' that could help develop new drugs.

In 1942, scientists first isolated an aromatic compound known as stypitic acid from mushrooms. By 1945, the structure of this substance had been studied, but it turned out to be so unique that it revolutionized organic chemistry.

Stipitatic acid is very unusual. It shows properties similar to the aromatic six-membered rings of benzene, but is a seven-membered carbon rings known as tropolones. Until now, it was a mystery how fungi synthesize such a substance using biological processes, because chemists managed to produce tropolone rings only with the help of complex chemical reactions in the presence of nickel and platinum.

Using a combination of genetic and chemical methods, scientists have for the first time identified the genes responsible for the production of tropolones in mushrooms. The researchers blocked the synthesis process at various stages and thus restored the pattern of synthesis at the molecular level.

Stipitatic acid is the basis of a number of fungal compounds that can be used to make antidepressants, antimalarials, and antibacterials. The discovery of the biosynthetic process for tropolone could lead to the creation of cheap and efficient methods for the production of new drugs.

Currently, scientists plan to use genetic engineering to create mushrooms capable of producing new medicinal compounds.
