Why is a camel depicted on the flag of the Chelyabinsk region, although they are not found there?

Camels are not found in the Chelyabinsk region, however, it is a camel that is depicted on the flag and coat of arms of Chelyabinsk, as well as on the flag of the Chelyabinsk region. This is explained by the fact that in the 19th century the main source of income for the city was trade, thanks to which many camels passed here as part of caravans.

When did the first theater appear?

Theater as we know it originated in Greece as part of a religious ritual. The stage was a circle covered with turf, on which the faithful danced around the altar of Dionysus. The stage was usually located at the foot of the hill so that the audience, who sat on its slopes, could see the dancers. This marked the beginning of the traditional arrangement of Greek theaters - a semicircle of seats located on the slopes of a hill.

The word "theatre" is of Greek origin and means "a place for viewing". Theater built in Athens around 500 BC. e., was round and was called parterre. There were performances. Outside the circle, special rooms were built that looked very majestic. This was the prototype of the current scene. These rooms served as a dressing room for the participants in the performance. They were also the screen that became the backdrop for the action of the play. The Greeks made very little use of decorations and did not resort to artificial lighting at all, because the plays were staged during the daytime.

In Rome, the first stone theater was built in 52 BC. e. Roman theaters were very similar to Greek ones, but they were built on level ground. The Romans were the first to install seats in the stalls, and the piece was played on a raised stage behind which was a screen. After the Romans converted to Christianity, no theaters were built for thousands of years.

The first modern theater was the Farnesi Theater in Parma, Italy. It was built in 1618 or 1619. His stage did not move far into the hall, into the stalls, but was located along one of the walls. A curtain was used to separate the auditorium from the stage, and the change of scenery could be done out of sight of the audience.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Microscope for examining the brain without opening the skull 30.09.2022

Korean scientists have invented a very unusual microscope. With it, you can create high-resolution XNUMXD images of a neural network without trepanation.

A new type of holographic microscope has been developed by a research team led by Choi Wonshik, deputy director of the Center for Molecular Spectroscopy and Dynamics of the Institute of Basic Sciences, Professor Kim Moonseok from the Catholic University of Korea and Professor Choi Myunghwan from Seoul National University.

The novelty is based on holographic technology. Researchers have developed a way to better select singly scattered waves, using the fact that they have similar reflection shapes even when light hits from different angles.

At the same time, in their project, the specialists used a rather complicated algorithm, as well as a numerical operation that analyzes distortion and interference between different waves of light.

As a result, they got a microscope that captures more than 80 times more light energy on nerve fibers than before. This allowed them to examine the patient's brain in detail without resorting to opening his skull.

One of the authors, Choi Wonshik, stated: "For a long time, our Center has been developing ultra-deep bioimaging technology that uses physical principles. It is expected that this discovery will make a significant contribution to the development of biomedical research, including neuroscience and the field of precision research."
