5. COMFORT PERFORMANCE AND HUMAN PERFORMANCE

The best indicators of working capacity and rest are achieved in a comfortable state and with rational modes of work and rest.

Comfort - the optimal combination of microclimate parameters, amenities, livability and comfort in areas of human activity and recreation.

With a comfortable microclimate, the physiological processes of thermoregulation are not stressed, the functional state of the nervous system is optimal, physical and mental performance is high, the body is resistant to negative environmental factors. Comfortable and permissible parameters of the air environment in the working areas regulated by state standards and are provided mainly by the use of air conditioning, ventilation and heating systems. The normative values of the microclimate parameters in the working areas of industrial premises depend on the category of work, the period of the year and other indicators.

plays an important role in achieving effective performance artificial lighting, which can have a psychophysical effect, relieve tension in the visual organs, and increase the safety of activities.

Operational efficiency people depends on workplace organization; correct location and layout of the workplace; providing a comfortable posture and freedom of movement; using equipment that meets ergonomic requirements. The microclimate of industrial premises is characterized by a wide variety of combinations of temperature, humidity, air velocity, intensity and composition of radiant heat, is dynamic and depends on fluctuations in external weather conditions, seasons and days, the course and nature of the production process, air exchange conditions with the atmosphere. So, with a uncomfortable microclimate, there is a tension in the processes of thermoregulation. When performing physical work, the limits of thermoregulation decrease.

With changes in the microclimate that go beyond the boundaries of adaptive physiological fluctuations, discomfort manifests itself in the form changes in well-being. Apathy, tinnitus, flickering before the eyes, nausea, confusion, increased body temperature, convulsions and other symptoms appear. Therefore, in ensuring comfortable microclimate parameters, the installation of efficient heating, proper ventilation, air conditioning, and thermal insulation of heat sources are important.

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 ... >>

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 ... >>

Embryo from stem cells 10.09.2023

Scientists from the University of Cambridge and the California Institute of Technology have made significant progress in growing artificial "near-embryos" from stem cells. The experiment provides new opportunities for research into genetic disorders, but also raises serious questions about morality and legality by creating structures that closely resemble the human embryo.

The embryo created had absolutely no relation to eggs or sperm and was devoid of a heart or brain development. However, it contained cells that form the placenta, the yolk sac, and the embryo itself.

This progress has been achieved by reprogramming embryonic stem cells. Despite this, the use of synthetic embryos for clinical purposes is not possible in the near future. This would be a flagrant violation of the law and it remains unclear whether such structures can develop further after the early stages of formation.

The researchers hope that these models will be useful in understanding the "black box" of human development, that is, the period after 14 days from the moment of fertilization, which is legally established as the deadline for culturing and studying embryos in the laboratory.

Robin Lovell-Bedge, head of the department of stem cell biology and developmental genetics at the Francis Crick Institute in London, explained: "The idea is that by creating normal human embryonic development using stem cells, we can gain a lot of information about the early stages of development and identify potential harm by avoiding the use of early embryos for research."

Previously, the same team of scientists demonstrated how mouse stem cells are able to develop into early embryo-like structures. These structures included the intestines, early forms of the brain, and even the beating heart. Currently, researchers are actively working on creating similar human models.
