Which states wanted to extend their sovereignty to outer space over their territories?

In 1976, the equatorial states of Colombia, Brazil, Ecuador, Indonesia, Kenya, Uganda, Congo and Zaire signed an agreement extending their sovereignty to the part of outer space above their territories in which geostationary satellites orbit. This provision was even enshrined in the constitution of Colombia. The declaration was not recognized by either the UN or separately by any of the countries with a developed space program.

How does the brain communicate its commands to the body?

The brain can, in a matter of seconds, receive signals from various organs of the body, process them and send commands to these organs to perform one or another action. Different parts of the brain are responsible for different functions of the body. The medulla, the upper portion of the spinal cord, controls nerves associated with many muscles and endocrine glands. This is a very important center responsible for the contraction of the heart, which distills blood, the work of the lungs, which processes the air we breathe, and the work of the stomach, which digests our food.

The cerebellum controls body movement and coordination. The large hemispheres of the brain are responsible for thought processes, assimilation of the new, remembering the already known, awareness of phenomena, decision-making. It is also the center of sight, hearing, smell, taste and touch. There is also a zone of feelings.

Scientists still cannot answer many questions about how the brain works. But they found that the signals that go to and from the brain are weak electrical discharges. Nerves are made up of nerve cells. Each of them consists of a body and thread-like processes emerging from it. Signals go from cell to cell along these processes.

Billions of nerve cells form an extensive network in a person connected with the spinal cord. Nerve fibers meet on their way to the spinal cord and intertwine into bundles. A thick bundle of this kind leads through the spine to the brain. Some of these nerves transmit messages from the sense organs to the brain, while the other part transmits commands from the brain to the muscles and endocrine glands. The brain sorts the signals it receives and, having made the appropriate conclusions, sends the signals in the right direction.

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 ... >>

Sony MDR-HW9.1DS 700 Wireless Headphones 09.04.2014

Sony introduced the MDR-HW700DS wireless headphones, which, according to the manufacturer, are the world's first wireless headphones with support for ten-channel surround sound (9.1).

For multi-channel sound reproduction, the headphones use Sony's exclusive Virtualphones Technology (VPT), which complements the basic 5.1 package with two more rear and two front top drivers. With multiple modes to choose from, the Sony MDR-HW700DS user is said to be able to optimize surround sound for movies, games and other sources.

The headphones use emitters with a diameter of 50 mm. The declared range of reproducible frequencies is 5-25000 Hz.

The sound processor, made in a separate unit, weighs 430 g. It is equipped with three HDMI inputs, an optical digital input and an analog stereo input. The list of decodable formats includes Dolby TrueHD, DTS, Linear PCM 2ch/5.1ch/7.1ch, Dolby Digital Plus, Dolby Digital , DTS-HD Master Audio, DTS-HD High Resolution Audio, DTS Express, DTS Digital Surround, DTS-ES, DTS 96/24. Wireless connection is made in the 2,4 GHz, 5,2 GHz and 5,8 GHz bands. Headphones weigh 320 g. Their battery charges in 3 hours and provides up to 12 hours of battery life.

At the same time, two more models of wireless headphones were also presented, according to the manufacturer, available for a wider range of consumers: MDR-HW300K and MDR-RF811RK. They use emitters with a diameter of 40 mm. The frequency response of the first model is 10-22000 Hz, the second one is 20-20000 Hz. For wireless connection, in the first case, the 2,4 GHz band is used, in the second, the FM band, the communication range reaches 30 and 100 m, respectively.

The MDR-HW300K headphones weigh 190g and have a battery life of up to 10 hours. It takes 3 hours to fully charge the battery. The MDR-RF811RK headphones weigh 270g and have a battery life of up to 13 hours, but their battery takes 16 hours to fully charge. In 1 hour, it can be charged to a level sufficient for operation for 45 minutes. If you use the AAA cell, the battery life is up to 28 hours.
