Long-term consequences of harmful, traumatic and damaging factors. Basics of safe life

Fundamentals of Safe Life Activities (OBZhD)

Harmful, traumatic and damaging factors do not act selectively, they negatively affect all components of the "human - technosphere" and "technosphere - natural environment" systems simultaneously if they are in the zone of influence of hazards. In addition, the growth of anthropogenic negative impact on the environment is not always limited to the growth of only direct hazards. Under certain conditions, the appearance of long-term consequences of negative impacts is possible, which can occur at the regional and global levels, have a negative impact on regions of the biosphere and significant groups of people. These consequences include the processes of formation of acid rain, smog, the "greenhouse effect", the destruction of the ozone layer of the Earth, the accumulation of toxic and carcinogenic substances in the organisms of animals and fish, in food products, etc.

Despite the fact that traumatic impacts affect short-term and spontaneously, as well as in a limited space, occur during accidents and disasters, explosions and sudden destruction of buildings and structures, they have long-term consequences characterized by long-term or periodic negative impacts on humans and the natural environment, elements of the technosphere. At the same time, the spatial zones of harmful effects vary over a wide range from working and domestic zones to the size of the entire earthly space. These include the impact of emissions of greenhouse and ozone-depleting gases, the release of radioactive substances into the atmosphere, etc.

The impact of traumatic factors leads to injury or death of people, accompanied by focal destruction of the natural environment and the technosphere, they are also characterized by significant material losses. Prolonged exposure to traumatic factors has a negative impact on the health of people, leading to occupational diseases.

Influencing the natural environment, harmful factors lead to the degradation of representatives of flora and fauna, change the composition of the components of the biosphere. At high concentrations of harmful substances or at high energy flows, harmful factors, by the nature of their impact, can approach traumatic effects. For example, high concentrations of toxic substances in the air, water, or food can cause poisoning.

Thus, man-made hazards worsen people's health, lead to injuries, material losses and degradation of the natural environment.

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. ... >>

80-channel optical link switch 13.04.2003

FUJITSU COMPONENTS announced the creation of an 80-channel optical communication switch that uses microelectromechanical mirrors.

The switching speed is 1 ms. The new switch is expected to be applied to the next generation of optical cross-connect systems. The company released a device called the "Universal Energy Standard" 6100A.

The device is designed for verification and calibration of devices for measurements in electrical networks and provides the generation of such signals: a pure sinusoidal signal, a signal with harmonic distortion, a signal with various types of noise. Signals are formed on 4 phases, which allows you to test any equipment.
