Focus Description:

A piece of sugar placed in a glass of hot tea quickly dissolves and the tea becomes sweet. With one trick, make the lump of sugar float to the surface and still make the tea sweet!

Focus secret:

The trick is that one piece of sugar (or several) is first lowered into the so-called collodion; then the sugar is dried for several days. If now such a lump of sugar is lowered into hot tea or water, then the sugar itself will dissolve, and a thin film of collodion, in the form of a lump of sugar, will float to the surface.

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 ... >>

Wind turbines affect the climate 03.05.2005

It is well known that the hydroelectric reservoir changes the climate in the surrounding area, and the thermal power plant, emitting carbon dioxide, affects the global climate. But now there is evidence that large wind farms, consisting of hundreds of windmills, can have a small but real impact on the climate of the surrounding area.

The height of modern wind turbines is up to 100 meters, the blade span is up to 50 meters, and even larger installations are being designed.

Computer simulations conducted at Duke University (USA) showed that large groups of windmills can increase wind speed near the ground by an average of 0,6 meters per second and increase air temperature by 0,7 degrees Celsius. At the same time, the evaporation of moisture from the soil will increase around the wind power plant by 0,3 millimeters per day.

All these data are averaged over 24 hours, and in the early morning the changes will be greater: the wind speed will increase by 1,5 meters per second in a few hours, and the temperature will increase by 2 degrees Celsius. The total capacity of the power plant of 44 generators is 30 megawatts.
