Fundamentals of Safe Life Activities (OBZhD)

To ensure the environmental safety of technical systems and technologies, ecobio-protection technology - means of protecting humans and the natural environment from dangerous and harmful factors.

Atmosphere protection from harmful substances is carried out by cleaning industrial air emissions from dust (dry and wet methods), fog with electrostatic precipitators and filters made of various materials), harmful gases (in adsorbers with and without chemical preparations) and vapors (condensation).

Hydrosphere protection is carried out by cleaning wastewater from polluting impurities with the extraction of all valuable substances from wastewater and their processing, or the destruction of harmful substances by oxidation or reduction, and then removing them in the form of gases and precipitation. To implement these methods, treatment facilities are used, through which all wastewater from industrial enterprises and city sewers must be passed.

For human protection in the conditions of production, as well as when interacting with technical means outside of production, various means are used that prevent or reduce the impact of dangerous and harmful factors to an acceptable level.

In particular, electrical installations must have protective grounding - connection of the installation case with a conductor under zero ground potential. In this case, electrical installations are grounded (electrical connection with a solidly grounded neutral of the current source of metal parts that may be energized) or protective shutdown (high-speed protection automatically turns off the electrical installation when there is a danger of electric shock to a person).

To protect against harmful substances in the workplace (for example, when soldering, working with adhesives, paints, laser processing of materials), local exhaust is used. ventilation.

Protective devices serve to protect moving parts of machines, places where particles of the processed material fly out, zones of exposure to high temperatures and harmful radiation.

vibration dampers (car and wagon springs), vibration isolators (rubber-metal shock absorbers, steel springs, etc.) protect a person from the harmful effects of vibration during low-frequency vibration, and sponge rubber gaskets - during high-frequency vibration.

Soundproofing increase solid panels made of vibration-damped material, glued from the inside to the body of the noise source.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

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 deformation is precisely reproduced in the second tissue that comes into contact with the baby's skin, allowing him to feel physical closeness, even at a distance.

Electrodes on both sides of the film react to deformation by changing its electrical capacitance. Intelligent algorithms predict and programmatically control the sequence of movements, controlling the deformation of the elastomeric film and emulating the parent's touch.

Artificial skin technology for virtual hugs opens new horizons in the field of virtual communication and intimacy. This development could be a valuable tool for those who are away from their loved ones, especially children quarantined in hospitals. Emulating touch from parents can bring solace and comfort to children during difficult times, as well as strengthen the bond between parents and children over a distance.
