29. INJURY AND HARMFUL FACTORS
Traumatic and harmful factors of the working environment are typical for most modern industries.
physical factors are:
1) dust content in the air of the working area during the processing of bulk materials, in the areas of knockout and cleaning of castings;
2) vibrations (general, local) that operate in the zone of vibration platforms, in vehicles, as well as in vibrating tools;
3) acoustic vibrations (infrasound, noise, ultrasound) near vibration platforms, powerful internal combustion engines and other high-energy systems, as well as near shock-type technological equipment, etc.;
4) static electricity in areas near DC electrical equipment, spray painting areas, synthetic materials;
5) electromagnetic field and radiation (infrared radiation, laser radiation, ultraviolet radiation, ionizing radiation) in areas near power lines, high-frequency drying and induction drying installations, electric lamp generators; in the areas of laser action, reflected laser radiation; in areas of welding and plasma treatment; in areas of radiation sources used in devices, etc.;
6) electric current in the areas of the electrical network, electrical installations, distributors, transformers, equipment with electrical wires, etc.;
7) moving machines, mechanisms, materials, products, parts of collapsing structures and others in the areas of ground transport, conveyors, pipelines, etc.;
8) height, falling objects in the areas of construction and installation works;
9) sharp fragments and edges in the area of cutting and piercing materials and tools, metal chips, fragments of brittle materials;
10) increased or decreased temperatures of surfaces of equipment and materials in various installations in case of leakage;
11) gas contamination of the working area due to the leakage of toxic gases and vapors from non-hermetic equipment, etc.;
12) dustiness of the working area during welding and plasma processing of materials containing chromium and manganese or their transportation.
К chemical factors include the ingress of poisons on the skin and mucous membranes in galvanic production, when filling containers, spraying liquids; as well as the ingestion of poisons into the gastrointestinal tract in cases of errors in the use of fluids or deliberate action.
К biological factors include cutting fluids used in the processing of materials using emulsols.
Psychophysical factors occur in the form of physical overloads (static, dynamic) during prolonged work with displays, work in an uncomfortable position or lifting them, transfer of gravity, manual labor and in the form of neuropsychic overloads (mental overstrain, overstrain of analyzers, monotony of work and emotional overloads), which found in scientists, operators of technical systems, air traffic controllers, as well as observers of production processes and creative workers.

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

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 ... >>
| Random news from the Archive Smart glasses Recon Jet HUD Pilot Edition
03.07.2013
Those interested in Recon Instruments' vision for the future of sunglasses can pre-order the Recon Jet HUD Pilot Edition for $500. This version of the goggle comes bundled with apps for cyclists and triathletes and should be out a few months before the final model is available.
The company even encourages you to place an order as soon as possible: the cost of the mentioned offer will increase to $21 from July 600. The interface and operation of the Pilot Edition version may be somewhat unstable, but if this does not scare you, you can place an order for unusual glasses on the official website.
The Recon Jet runs a modified version of the Android platform and includes, in addition to a WQVGA screen, a dual-core 2GHz processor with integrated graphics, 1GB RAM, 1GB internal flash memory, HD camera, speaker and microphone, Wi-Fi support, ANT+, Bluetooth, GPS and tons of sensors.
The manufacturer claims that the device is quite comparable in terms of capabilities with a smartphone and is quite light (electronics add 14 grams on each of the two sides of the sunglasses, and all together weighs 60 grams). The display is controlled using a touch panel, which can be operated even with gloves on. A replaceable battery is also available.
