Autism spectrum disorders (ASD) is a broad group of development disorders, which is united by the presence of qualitative disorders of social interaction, communication, as well as the repeated stereotypical nature of behavior and interests. Symptoms should be visible until the child reaches the age of three years. Autism is a clinical diagnosis, i.e. it is made only Based on observation of a child's behavior. The spectrum of autism is very wide. Before you may be a child with severe intellectual disability or, conversely, with high cognitive abilities, up to lightness...

Battery safety is determined by several parameters, primarily the difference in potential between the two electrodes — anode and cathode. The higher the difference, the more dangerous the system is. The second important factor is the presence or absence of organic components in the battery. For example, water electrolytes do not burn, unlike organic ones, and do not withstand the potential above 1.3-1.4 volts. The energy intensity of batteries depends on the potential difference. The higher it is, the more energy is available regarding mass or volume...

What is a nanoparticle? According to the definition of petrologists, the size of a nano-object should be less than 100 nanometers. One of the paradoxical examples is the bubble. In fact, it is also a nano-object: when we inflate a bubble, it changes color and its walls become almost invisible. As has been proven by optical scientists, at this point its wall thickness is less than 100 nanometers, and thus it is Nanoscale. However, scientists in the life sciences are much more likely to deal with nanoparticles in the form of round or elongated balls...

The history of the bio chips began with the analysis of DNA sequences Simultaneously, the interaction of the analyzed DNA molecules with the immobilized DNA probes in each cell ensures parallel identification of multiple genomic targets...

The main task of modern personalized medicine is to identify the risks of disease in a particular person. This will help to prevent diseases in advance and prescribe adequate treatment. It is possible to examine in detail the whole human body to understand what is affected in it, but it is an expensive process that takes a lot of time. That's why scientists have developed bio chips that reveal hundreds and thousands of bio markers in one analysis - compounds that indicate the presence of any disorder or susceptibility to disease...

Violation of the Treaty of Versailles The terms of the treaty from the defeated countries were mainly violated by Germany. The rest were readied to trade, including at the expense of Germany. It turned out that contract needed to be adjusted somehow. It turned out that in Germany there was almost no possibility to pay according to the terms of reparations. In 1923, the country experienced one of the largest inflation in world history. In the same year, the Communists revolted in Hamburg, and a Beer Putsch took place in Munich — Hitler's first attempt to seize power...

One hundred years ago, on June 28, 1919, the Treaty of Versailles was signed, which officially ended the First World War. This is the most important result of Paris Peace Conference, which was held after its completion in the period from 18 January 1919 to 21 January 1920. In the autumn of 1918, the allies of Germany — Bulgaria, Turkey, the disintegrating Austere -Hungarian Empire - one after the other began to conclude a truce. After that Germany concluded the Consensual Truce in November 1918....

Inc tic regions, it is advisable to use two options for voice communication. First is the classic radiotelephone communication, when a person dials a phone number in the usual way through the city code - for example, “8-499” — and thus communicates with people in other cities and countries. The second variant of the organization of speech or voice communication is a trunking communication — possibility of an urgent call through dispatching service!!!!!!!! There is a special button on the subscriber devices intended for this purpose to call the dispatcher on duty...

Reindeer: A resource around which northerners build their lives: a means of transportation, a major source of meat and skins. According to the latest estimates, there are 110 thousand domestic reindeer and 440-450 thousand wild reindeer in Taimyr. Traditionally, reindeer hunting, and has been developed in Evenkiyah, and reindeer herding has occupied a small place in the local population. In the last decade, domestic reindeer husbandry has been strengthened, but unfortunately 1,500-2,000 reindeer heads have survived...

Researchers have been looking for and looking for water on the moon. Why is it so important to know it exists? This information helps to clarify existing hypotheses about the origin of the satellite. The model of the Moon's impact formation says that once there was a collision of the Earth, which was a little more than now, with a space object the size of Mars. Part of the hot emissions were caught by the Earth's gravity field in Earth's near-Earth orbit. And these very hot particles then joined (accredited) into the Moon...

Mining of Soviet moon Soviet cosmonauts did not visit the Moon, Soviet automatic machines gave scientists a lot of new information. Thanks to lunar rovers, many images of the Moon's surface, albeit not of very high quality, were obtained. This helps, in particular, to choose the most suitable landing locations. The moon rovers were equipped with the Rhyming device, which studied the elemental composition of the surface using X-ray fluorescence analysis. The surface composition was measured at different locations...

Half a century ago, on July 21, 1969, the astronauts of the Apollo 11 mission, Neil Armstrong and Edwin Aldrin, stepped onto the surface of the Moon for the first time in human history. Before that, the Soviet, and American automatic stations flew to the Earth's satellite. Today, spacecraft continue to be sent to the Moon, but manned missions have ceased for many years. Although the Moon is the nearest celestial body to us, we still don't know much about it. What has it been possible to learn about...
