What is jadeite?

Jadeite is a translucent gemstone. Man has been cherishing it for thousands of years. In Chinese, the words "jadeite" and "precious stone" are one and the same. The English word "jadeite" comes from a Spanish expression that means "colic stone". The Spaniards called it that because they believed that jade cures stomach pains.

Jadeite is, in fact, one of two minerals - jadeite or jade. They are so similar to each other that only an expert can tell them apart. Jadeite is slightly harder than jade. It also has a translucent sheen and has a greater color range. Jadeite in its purest form is white, but there are enough mineral impurities in it that make jadeite bright yellow, red, or one of the many shades of green. The most desired shade is emerald green (or "imperial") jade, which can be almost transparent. This variety was found in Burma. Because jadeite is a hard and hard stone, primitive people used it to make axes, hammers, knives and other useful tools.

Later people used it to make bowls, carvings, jewelry and amulets. Jadeite is so hard that it is difficult to process: steel cutters won't take it, so gritty materials are used to rub the surface until it wears off. It may take 2-3 years of work to make a simple vase. Worked pieces of jadeite have been found in Mexico that are at least 3500 years old.

The first people in Central America used some jadeite as tools, but used this stone mostly for religious purposes. The Aztecs believed that jadeite was worth many times its weight in gold. China is a country where jadeite is of great importance.

For 3000 years, the Chinese have been making beautiful jadeite carvings. The Chinese admire jadeite so much that those who can afford it always carry small pieces with them. They believe that when jadeite is fingered, some of its latent powers are erased.

What is the Blue Ribbon?

The blue ribbon is a prize established in the 27th century. in the UK for passenger ships that have covered the distance from England to Australia faster than others. At the beginning of the XNUMXth century, the "Blue Ribbon of the Atlantic" was established - a prize for a passenger ship that covered the distance from England to North America faster than others. The first winner of this prize was the British liner Mauritania, which sailed at an average speed of XNUMX knots.

The Blue Ribbon of the Atlantic was successively won by the German Bremen (1929), the French Normandy (1935), the British Queen Mary in 1952 and in the same year the American liner United States, which set a hitherto unbroken record - 35,5 knots (about 66 km / h). He crossed the Atlantic in 3 days 10 hours. The famous "Titanic", also participating in the fight for this prize, sank in the North Atlantic as a result of a collision with an iceberg.

Since 1956, most passengers have already crossed the Atlantic by plane.

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 ... >>

Silk production using artificial spider gland 02.02.2024

Japanese scientists have managed to develop a device for creating artificial spider silk that is close to the natural production of spiders.

The achievement of Japanese specialists in creating rayon opens up new prospects for the textile and medical industries, shedding light on the future of environmentally sustainable materials production.

Silk is valued for its strength and lightness, but its natural extraction is difficult, which has prompted scientists to look for alternative production methods. A team of researchers from the RIKEN Center for Sustainable Resource Science and the RIKEN Pioneering Research Cluster in Japan has developed a new approach, creating a device that can reproduce the complex molecular structure of silk.

The device, which is a box with grooves, allows the solution to be moved from one end to the other using negative pressure, simulating the processes in the silk glands of spiders.

Study leader Keiji Numata explains: "We aimed to mimic the natural production of silk by spiders using microfluidics, which involves the flow and manipulation of fluid through narrow channels. The spider's silk gland essentially functions as a natural microfluidic device."

This technology could become the basis for the environmentally friendly production of silk for the textile industry and medicine.

Numata adds: "We are looking to make a real impact. To do this, we need to expand our fiber production methods and make them more continuous. We will evaluate the quality of rayon through various indicators and improve it."
