38. PROTECTION FROM TOXIC EMISSIONS

Toxic emissions from the environment enter the body through respiratory tract, through damaged and undamaged skin, through the gastrointestinal tract. Toxic effects of certain substances may appear as secondary lesions (for example, colitis due to arsenic and mercury poisoning, etc.). Toxic emissions, once released into the air, slowly settle on people’s lungs, making breathing difficult; on the skin, clogging the sweat glands, impeding sweating and evaporation, which interferes with the normal thermoregulatory process, reduces skin resistance and increases the penetration of microbes, and also causes allergic reactions.

General toxic effect on the human body dust of lead, manganese, antimony, not only causing poisoning, but also having an allergenic effect. At the same time, the filtering ability of the nasal cavity decreases, chronic inflammatory processes develop in other parts of the respiratory tract (silicosis of the lungs, tuberculosis), and bronchial asthma may develop. The fibrogenic effect of dust (proliferation of connective tissue in organs) depends on the content of free silicon dioxide.

In addition to dust concentrations hazardous to human health, there are explosive concentrations of organic dust: tobacco, flour, sugar, coal, leather, etc.

The basis for carrying out measures to combat toxic emissions are: Federal Laws “On Environmental Protection” 2002, “On the Protection of Atmospheric Air” 1999, “On the Sanitary and Epidemiological Welfare of the Population” 1999, Regulations on Harmful Emission Standards ( pollutants into the atmospheric air and harmful physical effects on it (Resolution of the Government of the Russian Federation of 2000), Decree of the Government of the Russian Federation "On approval of the Regulations on state control over the protection of atmospheric air" of 2001, etc.

The following measures are recommended to reduce dust levels from toxic air emissions:

1) isolation of sources of dust formation (sealing of equipment);

2) humidification of air and dust-forming substances;

3) hydro- and pneumotransportation of substances;

4) installation of dust and gas suction devices;

5) deposition of dust (aerosols) in acoustic and electric fields, which not only reduces dust in the air, but also helps to capture valuable production products;

6) use of the most rational means and methods of cleaning premises (vacuum cleaners, cleaning machines), dust deposition by spraying water;

7) the use of general and local exhaust ventilation;

8) use of personal protective equipment (gas masks, respirators, overalls, glasses, etc.).

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Mini air conditioner Sony Reon Pocket 5 09.05.2024

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

The tablet makes a diagnosis 14.11.2003

In the laboratories of the University of the Canadian city of Calgary, a pill is being developed that itself makes a diagnosis and, if necessary, treats.

In a tablet, not exceeding the size of a regular one, an electronic sensor is only 10 times larger than a red blood cell. When the tablet is swallowed, the sensor measures, for example, the temperature. If it is elevated, an antipyretic is released from a reservoir with a capacity of one milliliter.

The sensor can detect acidity and deliver an agent that normalizes it into the stomach. Moreover, the amount of the released drug depends on the magnitude of the deviation of the measured indicator from the norm. After one or two days, the pill that has done its job leaves the body naturally. Human trials have not yet been conducted.

Before moving on to them, the developers want to increase the capacity of the battery hidden in the tablet. It is enough for 4 hours of work, but it would be necessary to increase the charge at least three times.
