The impact of smoking on human health. Basics of safe life

Fundamentals of Safe Life Activities (OBZhD)

Tobacco smoking weakens and undermines health, reduces ability to work, shortens life expectancy. One of the most dangerous diseases of chemical dependence, attributed to bad habits, is smoking.

About 2,5 million people die prematurely among smokers each year. Smoking is especially dangerous in certain age periods - youth, old age. A lot of smokers are people who lead an unhealthy lifestyle or are busy with big, hard work and sleep little. But we must not forget that stimulation of the nervous system with nicotine leads to the depletion of a person's energy capabilities. Smoking in an intensive mode causes overwork and the phenomena of acute poisoning: headache, pallor, dryness and bitterness in the mouth, heart spasms.

A link has been established between tobacco smoking and the occurrence of cancer of the lips, tongue, larynx, trachea, bronchi and lungs. Especially when smoking, the respiratory organs are affected: chronic bronchitis of the smoker occurs, emphysema of the lungs gradually develops. Smokers are always worried about coughing.

Smoking leads to a violation of vitamin metabolism. There comes a lack of vitamin C, which is accompanied by irritability, fatigue, sleep disturbance, frequent colds. Insufficient assimilation of vitamin A leads to night blindness (impaired vision at dusk).

Tobacco smoke affects the central nervous system, first exciting and then depressing it. Under the influence of smoking, memory, attention, muscle strength weaken, working capacity decreases, intelligence falls.

Smoking contributes to the occurrence and worsens the course of a number of diseases of the cardiovascular system: atherosclerosis of the coronary vessels and myocardial infarction, hypertension, endarteritis, narrowing and blockage of small arteries of the vessels of the lower extremities). Acting on the digestive organs, tobacco combustion products cause inflammation, ulcers of the mucous membrane of the stomach, esophagus and intestines.

A smoking pregnant woman may have a miscarriage, premature birth, and a decrease in fetal weight. If a woman smokes during breastfeeding, then the child becomes weak, painful. Tobacco poisoning in childhood leads to a slowdown in the growth and overall development of the child, and disorders of the cardiovascular system occur.

Currently, non-smokers have begun to detect diseases inherent in smokers. This is due to passive smoking, i.e., when a person is forced to stay in a smoky room for a long time. In children of smoking parents, the frequency of bronchitis and pneumonia increases, and the risk of serious complications increases.

In passive smokers, hearing, vision, smell deteriorate, diseases of the lungs and the cardiovascular system appear, headaches, dizziness, weakness, and malaise occur.

Running forms of smoking require treatment, the initial ones can be interrupted by an effort of will and appropriate behavior. The biggest damage from smoking is serious illness, congenital deformities, disability and, as proven by science, premature death.

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. ... >>

Reliable SRAM memory with Hardsil technology 02.02.2015

Although most semiconductor products operate in relatively comfortable environments, there are applications that require increased reliability, resistance to high temperatures and other harmful factors.

Silicon Space Technology (SST) announced that its 18Mbps SRAM chips, manufactured using Hardsil's proprietary technology, have successfully passed performance testing at 250°C.

At the specified temperature, they worked without a single error for more than 1400 hours. During this time, 65 trillion read operations were performed. According to the manufacturer, this is a landmark achievement for the industry, setting a new bar for reliability standards for hardened microcircuits.

For comparison, the maximum temperature for which ordinary microcircuits are designed does not exceed 125°C, and in most cases even 70-85°C.

Microcircuits manufactured using SST Hardsil technology are designed for use in the oil and gas, aerospace and automotive industries. SST's "hardened" chips are said to provide related electronic equipment with trouble-free operation in real-life conditions for many years.

In addition to SRAM memory, the manufacturer offers ARM Cortex series processors and evaluation boards with them.
