1. CONTENT OF THE DISCIPLINE "LIFE SAFETY"

Safety of vital functions is a field of scientific knowledge covering the theory and practice of protecting a person from dangerous and harmful factors in all spheres of human activity, maintaining safety and health in the environment. This discipline solves such problem, as identification of negative impacts of the habitat; protection from dangers or prevention of the impact of certain negative factors on humans; elimination of negative consequences of exposure to dangerous and harmful factors; creating a comfortable state of the human environment.

The main indicator of life safety is life expectancy. Development civilizations, by which we mean the progress of science, technology, economics, industrialization of agriculture, the use of various types of energy, including nuclear, the creation of machines, mechanisms, the use of various types of fertilizers and pest control agents, significantly increases the number of harmful factors that negatively affect person.

Throughout its existence, the human population, developing the economy, created a socio-economic security system. As a result, despite the increase in the number of harmful effects, the level of human safety increased.

Human impact on the environment, according to the laws of physics, causes response counteractions of all its components. The human body painlessly endures certain influences as long as they do not exceed the limits of adaptation. The course "Life Safety" provides for the process of knowing the complex relationships of the human body and the environment, in connection with which the course covers:

1) safety in the domestic environment;

2) safety in the working environment;

3) life safety in the urban environment (residential area);

4) safety in the natural environment;

5) emergency situations of peacetime and wartime.

Living environment - this is the total sum of factors affecting a person in everyday life. The reaction of the body to everyday factors is studied by such branches of science as communal hygiene, food hygiene, hygiene of children and adolescents.

Work environment is a set of factors affecting a person in the process of labor activity.

Safety in the natural environment - This is one of the branches of ecology. Ecology studies the patterns of interaction of organisms with the environment.

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

Summer is a time for relaxation and travel, but often the heat can turn this time into an unbearable torment.

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 ... >>

Mokacam Miniature Modular Camera 13.12.2015

The market for ultra-compact cameras cannot be called empty. What is worth only the fact that after a few months of sales, the cost of GoPro Hero4 Session fell by half. And this despite the fact that GoPro is the leader in the "action camera" segment.

The creators of the Mokacam camera decided to somehow stand out and made their device modular. The camera itself is housed in a 45 x 45 x 35 mm body weighing 96 g and, according to the manufacturer, is the smallest 4K camera in the world.

It has a 16-megapixel Sony IMX206 sensor, a wide-angle lens (152 degrees), a Wi-Fi module, a microSD card slot, is protected from water and is capable of shooting 1080p video at 60 fps. But 4K video is recorded only at 15 fps, which casts doubt on the appropriateness of this mode. The battery capacity is 1000 mAh.

As for modularity, it is implemented quite simply. On the right side there is a special connector for connecting a small screen. He, in turn, has an additional battery capacity of 1100 mAh. In addition, on the back there is a magnetic mount for another battery of the same capacity. Actually, there are no other modules. By the way, thanks to the rear magnet, the camera can be mounted on metal surfaces. Deliveries should begin in a few months.

The cost of the camera for Indiegogo campaign participants starts at $100, while the final cost will be $170.
