Numeric keys can be operated individually or simultaneously. With an accuracy of VCEsat transistors, the output voltage will be determined by the formula V2 = Vref (l + R2 / R1), R1 < 1,6 kΩ, Vref - 2,77 V (the spread is from 2,64 to 2,86 V).
The maximum current is 2 A if there is no overheating of the crystal at high power dissipation. The instability of V1 is reduced to 0,001, the output resistance is 2,5 mΩ.

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 ... >>
| Random news from the Archive Greens against crime and disease
15.05.2010
As Francis Cuo, a US environmentalist, has shown, greening cities helps reduce crime. Dr. Kyuoh analyzed police statistics for downtown Chicago and compared them with the area occupied by green spaces in each block.
It turned out that in houses surrounded by greenery, crime is 52% lower than where there is only solid asphalt and parking lots around. In two other studies, the same author showed that if nature is visible from the windows of the house, and not monotonous buildings and traffic flows, the aggressiveness of the residents of the house is reduced by 27%.
And according to surgeons from Texas, if trees are visible from the window of the recovery room, then patients recover faster. They require fewer painkillers and experience fewer complications than patients who have undergone the same operation, lying in a room overlooking a brick wall.
