43. ECOBIOSECTION TECHNOLOGY

To ensure the environmental safety of technical systems and technologies, eco-bioprotective technology - means of protecting humans and the natural environment from dangerous and harmful factors.

Atmosphere protection from harmful substances is carried out by cleaning industrial air emissions from dust (dry and wet methods), fog with electrostatic precipitators and filters made of various materials), harmful gases (in adsorbers with and without chemical preparations) and vapors (condensation).

Hydrosphere protection is carried out by cleaning wastewater from polluting impurities with the extraction of all valuable substances from wastewater and their processing, or the destruction of harmful substances by oxidation or reduction, and then removing them in the form of gases and precipitation. To implement these methods, treatment facilities are used, through which all wastewater from industrial enterprises and city sewers must be passed.

For human protection in the conditions of production, as well as when interacting with technical means outside of production, various means are used that prevent or reduce the impact of dangerous and harmful factors to an acceptable level.

In particular, electrical installations must have protective grounding - connection of the installation case with a conductor under zero ground potential. In this case, electrical installations are grounded (electrical connection with a solidly grounded neutral of the current source of metal parts that may be energized) or protective shutdown (high-speed protection automatically turns off the electrical installation when there is a danger of electric shock to a person).

To protect against harmful substances in the workplace (for example, when soldering, working with adhesives, paints, laser processing of materials), local exhaust is used. ventilation.

Protective devices serve to protect moving parts of machines, places where particles of the processed material fly out, zones of exposure to high temperatures and harmful radiation.

vibration dampers (car and wagon springs), vibration isolators (rubber-metal shock absorbers, steel springs, etc.) protect a person from the harmful effects of vibration during low-frequency vibration, and sponge rubber gaskets - during high-frequency vibration.

Soundproofing increase solid panels made of vibration-damped material, glued from the inside to the body of the noise source.

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 ... >>

NASA spacecraft was able to withstand an explosion on the Sun 19.09.2023

NASA's Parker space probe made a historic discovery, becoming the first vehicle to overcome a coronal mass ejection on the Sun and confirm the existence of interactions between solar particles and interplanetary dust.

The Parker solar probe passed through one of the most powerful coronal mass ejections recorded in the history of space exploration. The device's equipment for the first time recorded the interaction between charged particles ejected by the Sun and tiny dust particles inhabiting interplanetary space.

Using the large-format WISPR camera, Parker tracked the interaction of coronal mass ejection particles and dust, analyzing changes in brightness in the images. Because dust particles scatter and reflect light, areas with high concentrations of dust particles glow more brightly. The scientists calculated the average brightness in WISPR images during orbital motion and demonstrated changes in luminosity within the coronal ejection.

Although the Parker probe completed four orbits around the Sun, changes in observations were only noted during the September 5, 2022 event. This leads scientists to believe that only powerful emissions have a significant impact on the distribution of interplanetary dust. The physical mechanism of this process is still poorly understood, but understanding it is critical for predicting space weather.

Interplanetary dust is made up of tiny particles originating from asteroids, comets and even planets, and is distributed throughout the solar system. The dim light seen on Earth some days before dawn or after sunset is the result of our planet colliding with a cloud of interplanetary dust.

Already in 2003, scientists suggested that charged solar plasma particles in coronal mass ejections interact with interplanetary dust and may even push it away from the Sun. Until now, this hypothesis has remained unconfirmed, since visible manifestations of this interaction are observed only near the Sun.
