11. The passage around the mortar mixer must be at least 1 m wide, the workplace must be equipped with a protective visor.

The connection of the mortar mixer to the network must be carried out by the electrician on duty. It is forbidden for the driver to independently connect the compressor to the mains and to the grounding center;

12. During the operation of the mortar mixer, the driver must:

a) ensure the maintenance of the mortar mixer and control the presence of lubrication on rubbing surfaces, the satisfactory condition of the bearings, electric motor, gearboxes (avoiding overheating), the presence and serviceability of limit switches and guards;

b) load the container for mixing the solution when it returns to its original position and is installed on the stopper;

c) control the lifting and lowering of the loading bucket;

d) do not allow the use of improvised means to speed up the unloading of the finished solution.

13. When receiving and storing materials necessary for the preparation of the solution, the following requirements should be met:

a) place sand on leveled and compacted areas, leaving a passage at least 1 m wide;

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. ... >>

IQ is not related to a person's level of intelligence 01.11.2016

The American scientist James Flynn conducted an interesting study, during which he came to the conclusion that over 50 years the general level of intelligence in people has increased, but the level of human consciousness has not improved.

Together with colleagues from the University of Otago in New Zealand, psychology professor James Flynn organized a study whose results disprove the theory that IQ is directly related to intelligence.

Experts argue that intelligence abilities do not actually correlate with IQ indicators, and a person’s mental achievements depend on a number of other factors, including family, and not just genetic predisposition, as previously thought.

Flynn said that on a daily basis he observes smart students who have high potential and are easily managed with modern technologies. However, they are completely indifferent to the history of the world. The scientist is convinced that once outside the walls of the university, they will not differ from the medieval peasants, locked in their cramped "world".

Moreover, the psychologist noted that the worldview of the modern generation is too superficial. Despite the fact that with the development of high technologies, people have developed abstract thinking, and, in turn, the coefficient of intelligence has increased, people still have not learned how to use the potential of their abilities, which allows a number of structures, including political ones, to manipulate their consciousness .
