Fundamentals of Safe Life Activities (OBZhD)

The best indicators of working capacity and rest are achieved in a comfortable state and with rational modes of work and rest.

Comfort - the optimal combination of microclimate parameters, amenities, livability and comfort in areas of human activity and recreation.

With a comfortable microclimate, the physiological processes of thermoregulation are not stressed, the functional state of the nervous system is optimal, physical and mental performance is high, the body is resistant to negative environmental factors. Comfortable and permissible parameters of the air environment in the working areas regulated by state standards and are provided mainly by the use of air conditioning, ventilation and heating systems. The normative values of the microclimate parameters in the working areas of industrial premises depend on the category of work, the period of the year and other indicators.

plays an important role in achieving effective performance artificial lighting, which is capable of exerting a psychophysical effect, relieving the tension of the organs of vision, and increasing the safety of activities.

Operational efficiency people depends on workplace organization; correct location and layout of the workplace; providing a comfortable posture and freedom of movement; using equipment that meets ergonomic requirements. The microclimate of industrial premises is characterized by a wide variety of combinations of temperature, humidity, air velocity, intensity and composition of radiant heat, is dynamic and depends on fluctuations in external weather conditions, seasons and days, the course and nature of the production process, air exchange conditions with the atmosphere. So, with a uncomfortable microclimate, there is a tension in the processes of thermoregulation. When performing physical work, the limits of thermoregulation decrease.

With changes in the microclimate that go beyond the boundaries of adaptive physiological fluctuations, discomfort manifests itself in the form changes in well-being. Apathy, tinnitus, flickering before the eyes, nausea, clouding of consciousness, fever, convulsions and other symptoms appear. Therefore, in ensuring comfortable microclimate parameters, it is important to install rational heating, proper ventilation, air conditioning, and thermal insulation of heat sources.

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 ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

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. ... >>

gold mining bacteria 24.01.2018

Geologists in Queensland, Australia have discovered a unique new type of beneficial bacteria that picks up the smallest grains of gold and processes them into larger bars called nuggets. This discovery will allow mining companies to develop previously unpromising deposits, but the most interesting area of \uXNUMXb\uXNUMXbapplication for new bacteria will be the processing and extraction of gold from old electronics.

"E-waste contains quite a lot of gold and some other precious metals," says Frank Reith, professor at the University of Adelaide. the amount of which is in every mobile phone or computer"

The e-waste, old mobile phones, computers, TVs, etc. thrown away in 2016 around the world contained $84 billion worth of valuable materials, of which $29 billion was the value of gold. “Now we are experimenting with various types of electronic waste and developing a complete technological cycle for extracting gold from it, the main “actors” of which are new bacteria,” says Dr Ollie Crush, a scientist working for the New Zealand Mint.

The found bacteria work by processing various alloys in their womb and filtering out all metals except gold. As a result, the bacterium forms a nanoparticle of high purity gold, which is attached to the "embryo" of the future nugget. This is a rather slow process, the procedure for the complete extraction of gold from e-waste can take from 17 to 58 years, which is very, very long in order to consider the possibility of practical application of the "bacterial" method of extracting gold.

However, scientists working with new bacteria are going to involve genetic scientists in the near future. And, it is likely that geneticists will be able to find and carry out appropriate genetic changes that will greatly accelerate the "gold-mining function" of a new strain of these extremely beneficial bacteria.
