Application of solar modules

Section Alternative energy sources. A solar module is a battery of interconnected solar cells housed under a glass cover. The more intense the light falling on the photocells and the larger their area, the more electricity is generated and the greater the current. Modules are classified by peak power in watts (Wp). Watt is a unit of measurement of power. One peak watt is a technical characteristic that indicates the power value of an installation under certain conditions, i.e. when solar radiation of 1 kW/m2 falls on the element at a temperature of 25°C ... >>

Section Electronics in medicine. The human body produces weak electrical impulses and responds to their impact. More I.P. Pavlov emphasized that strong reactions of the body can be caused by weak influences. This principle is based on the electropuncture effect on biologically active points of the body (BAP) according to the method of acupuncture (zhen-jiu therapy, acupuncture). The method of zhen-jiu therapy arose on the basis of empirical data 4-5 millennia ago (in the Stone Age) in China [1]. Millennia later, this method was systematized and described. And today, the classic points of the meridian teaching have been supplemented with hundreds of new extra-channel points and zones. With the development of technology, the ancient acupuncture and cauterization of BAP were supplemented with electropuncture, laser puncture, electroacupuncture, light and magnetotherapy. In terms of their effect on the body, all methods are considered as a reflex process, which is based on a complex neurohumoral reaction that occurs in response to BAP irritation. ... >>

Blinking of the magician and his audience 19.05.2024

Magic and illusions have always captured the attention of the public, but what happens behind the scenes of the magician and in the brains of his audience? Scientists from the UK decided to solve this mystery by conducting a new study involving ten illusionists of varying experience. Illusionists, some of whom had been practicing magic for more than half a century, others for only six months, were invited to demonstrate the same trick - the popular coin trick. Recordings of their performances during training and on stage showed that each of them began to blink significantly more often at the moment of performing the trick. The study's findings indicate that magicians' blink rate may be related to unconscious aspects of their performance. At the same time, as scientists have found, spectators also begin to blink more often, following the movements of the illusionist. This observation supports the idea that magicians may be catalysts for blinking in audiences. Additional research has shown that magicians blink more often during ... >>

Ultrasonic coffee machine 19.05.2024

Iced coffee has become an integral part of coffee culture in recent years. Therefore, engineers from the University of New South Wales decided to improve its preparation. They have developed an ultrasonic coffee machine that reduces the cold brew time for ground coffee beans from 12-24 hours to significantly less time. Iced coffee, or "Cold brew", is popular due to its smoothness, low acidity and low bitterness. It is prepared by steeping ground coffee in cold water for a long time. Unlike traditional hot brewing, which often imparts bitterness to coffee, cold brewing extracts more delicate and complex flavors from the coffee beans. The innovative system, presented by a team of engineers, introduces ultrasonic technology into the coffee preparation process. The system uses ultrasonic waves to speed up the process of extracting oils, flavor and aroma from ground coffee. This allows you to significantly reduce the time ... >>

The speech of sperm whales is similar to that of humans 18.05.2024

In the world of the ocean, where the mysterious and unknown coexists with the studied, sperm whales, with their huge brains, are of particular interest to science. Researchers, working with a huge array of audio recordings collected during the Dominica Sperm Whale Project (DSWP) - more than 8000 recordings, seek to unravel the secrets of their communication and understand the structure and complexity of the language of these mysterious creatures. By studying in detail the recordings of 60 sperm whales in the eastern Caribbean, scientists have revealed surprising features of their communication, revealing the complexity of their language. "Our observations indicate that these whales have a highly developed combinatorial communication system, including rubato and ornaments, which indicates their ability to quickly adapt and vary during communication. Despite significant differences in evolution, sperm whales have elements in their communication that are characteristic of human communication," says Shane Gero, a biologist at Carleton University and director of the CETI project.

The hippocampus helps you navigate in space 05.06.2016

Scientists from the RIKEN Brain Science Institute (Japan), led by Thomas McHugh and Steven Middleton, studied the work of the hippocampus of laboratory mice and found out that it is he who allows the animal to determine its location in the environment and play the role of a kind of mental map, in which spatial information is "inscribed". The experiment showed that this map is quite easy to damage and leave the animal at a loss about where it is and where it is going - it is only necessary to destroy the neural connections between the zones of the hippocampus.

McHugh's team determined that the main role in the formation of an idea of ​​the environment in mice is played by neural impulses emanating from the CA3 zone of the hippocampus to other zones, in particular, to CA1, which directly depends on them (there are only four zones in the hippocampus - CA1, CA2, CAZ and CA 4. The abbreviation CA is from the Latin Cornu Ammonis "Ammon's horn"). The key to constant updating of the spatial map is the rhythmic flow of such impulses.

To study the consequences that would arise if there was a violation of the uniform flow of synaptic impulses from the SAZ to other areas of the hippocampus, scientists introduced neurotoxins into the SAZ, which “drowned out” the signals emanating from it. The result was a loss of orientation in space, a violation of the mental map and "entanglement" - the animal ceased to determine its location and could not assess the environment.

It became clear that correct orientation on the ground directly depends on the ability of the hippocampus to systematically form and maintain synaptic connections between areas - this does not allow errors in neural impulses to mix and destroy spatial information, including in sleep.
