How long is the Great Wall of China?

The Great Wall, or, as the Chinese call it, the Long Wall, stretched across the whole of Northern China for 4 kilometers. It began to be built in the 9th-6rd centuries BC, when individual Chinese states were forced to defend themselves from the raids of the nomads of Central Asia. All work on this gigantic building was completed in the 10rd century. The western part of the Great Wall has been preserved in its original form to this day. Eastern - collapsed and in some places turned into an earthen rampart. The width of the wall at the base is XNUMX meters, at the top - XNUMX meters, the height - XNUMX meters.

Approximately every 200 meters on the wall there are quadrangular watchtowers with loopholes. At the top, a paved road runs along the wall. Once upon a time, military units and convoys could quickly move along it. Today, some sections of this road are covered with asphalt, and cars drive along the Great Wall.

The western part of the Great Wall runs along the loess plateau in the upper reaches of the largest Chinese rivers - the Yellow River and the Yangtze. Loess is a rock that is inflicted by rivers. Huang He and Yangtze originate in the Tibetan Plateau (this is a whole country, which is formed not only by mountains, but also by plateaus).

From the foot of the mountains to the coasts of the Yellow and East China Seas stretches the Great Chinese Plain, formed by the valleys of these rivers. On it, the Chinese grow rice and many other crops. The Great Chinese Canal stretches across the entire Great Plain of China, the length of which is 1700 kilometers, built in ancient times.

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 ... >>

Polyethylene liquid fuel 04.02.2022

Polyethylene is the most common plastic in the world. More than 100 tons are produced every year. The problem is that it is an incredibly inert material that does not react with almost anything, and therefore does not decompose under natural conditions.

Zheng Huan, a chemist at the Chinese Academy of Sciences, was able to decompose polyethylene at 150 degrees Celsius by adding an organometallic catalyst, a small, commercially available organic molecule containing iridium. The catalyst weakens the bonds responsible for the strong structure of polyethylene, accelerating its decomposition and turning it into a liquid product.

"The resulting products are much cleaner than conventional incineration products," Huang says, adding that the reaction is easier to control and the liquid can be used as a fuel.

So far, the process has been demonstrated on small samples of plastic bags, bottles, and food packaging.

Now scientists are facing two problems: firstly, to increase production and try to bring a new method to an industrial level, and, secondly, to replace iridium - a rare and precious platinum metal - with something cheaper, although there may be a problem, since metal Catalysts, due to their specificity, cannot simply be replaced. But Chinese chemists remain optimistic and assure that they will soon be able to produce new material in liters and even tons.
