What is the difference between the words tea and tea?

The character for tea, 茶, is pronounced "cha" in most Chinese dialects. Such a pronunciation with variations became common in countries where tea came from China with trade caravans by land: these are Central and Asia Minor, India, Russia, and the Arab states. However, in the Min languages spoken in the coastal province of Fujian, the same character is pronounced "te". From here, through Indonesia, tea was brought to Europe by Dutch merchants, and therefore in most European languages the drink is called similarly: tea in English, thé in French, Tee in German. The only exceptions are the Portuguese, who also carried tea by sea, but from the ports of Hong Kong and Macau, where they speak Cantonese - therefore the drink is called chá in Portuguese.

What makes a balloon rise up?

A hot air balloon is the simplest aeronautical apparatus. It usually consists of a light spherical or cylindrical "bag" made of paper, rubber, silk or rubberized material containing hot air, hydrogen or helium inside. A basket, or a gondola, in which passengers and goods are transported, can be attached to the ball using ropes or a net. The ball floats in the air for the same reason a fish swims in water. Each of them displaces from the water or air surrounding them, a mass greater than their own.

As long as the balloon and its gear weigh less than the displaced air, it will rise. If it loses some of the gas that lifts it and its mass increases, it will begin to fall. Hot air, hydrogen or helium is used as the lifting gas because they are all lighter than normal atmospheric air. The released balloon will rise until the weight of the displaced air is equal to its own.

In order to change the flight altitude, the aeronaut must either reduce his lifting forces in order to descend, or reduce his weight in order to ascend. To descend, he must release some gas through a valve at the top of the balloon. To rise higher, he must throw part of the cargo (ballast) overboard. Since neither ballast nor gas can be replenished during flight, it is obvious that the balloonist's ability to control the flight of the balloon is severely limited. At best, it can only rise and fall for a more or less short period of time, depending on the size of the ball.

Rising up, the ball falls into complete dependence on the winds. In flight, the balloon is almost impossible to direct. It can only sail with the wind, and for this reason it is of very little use as a vehicle. These days, hot air balloons are mainly used to explore the upper atmosphere. During the war, they were used as air observation posts, and they also built a kind of air barriers (something like air fences) to protect cities from bomber raids.

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 ... >>

Sapper rats are better than metal detectors 28.09.2015

In Cambodia, where more than 1970 million anti-personnel mines were planted during the civil war in the 6s, unexpected helpers are used to detect mines. They turned out to be specially trained rats that work not only better than metal detectors, but also sapper dogs.

Gambian hamster rats not only sniff out mines faster, but also cover large areas at a much faster rate than larger sappers. Due to their weight, rats cannot be blown up by an anti-personnel mine, their sense of smell is much stronger than that of dogs, and they work autonomously, without the handler that dogs need.

Rodent sappers are trained by the non-profit organization "Apopo", which was founded in 1998 by the creator of the project, Bart Vidzhens, an engineer from Antwerp. Rats are trained from birth to sniff out TNT, after which they must explore the training minefield and correctly mark the place where they found the mine, after which the rodents receive a reward. After nine months of training, the rats are ready to start the real demining.

On the spot, the rats are put on a collar and led around the field with a long pole. Having found a mine, the rodent does not try to dig it out, but only mark it so that specially trained people will take care of the projectile. Rats are incredibly efficient, covering a 200-square-meter area in thirty minutes, while it takes at least three days for human sappers.

After five years of work, the sapper rodents retire and live out the rest of their lives at the Apopo headquarters in Tanzania, where they are cared for and fed.

In total, Gambian rats have found 56 mines and unexploded ordnance since the organization's inception and cleared an area of about 000 million square meters.
