Comments on the article

Scheme for switching on halogen lamps of mains voltage does not differ from that for conventional incandescent lamps.

Low voltage lamps eat from special transformers, and due to high currents (up to 8 A per lamp), instead of laying a single low-voltage network, several groups of lamps with separate transformers supplying them are usually used. Halogen lamps are not sensitive to the type of supply current (AC or DC).

Luminous flux regulation network lamps is carried out by any standard dimmers similar to incandescent lamps. The possibility and method of regulation of low-voltage lamps is completely determined by the type of transformer.

Council. It should be noted that when reducing the power of a halogen lamp using dimmers, the operation of the halogen cycle is disrupted, and this can lead to a decrease in the life of the filament. To prevent this from happening, it is recommended to periodically turn on the lamp at full power, thus ensuring the restoration of the spiral material.

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 ... >>

Intercontinental flights of pterosaurs 09.01.2011

According to the American paleontologist Michael Habib, large pterosaurs could make non-stop intercontinental flights 65 million years ago.

In 1975, the remains of a huge pterosaur were discovered in Texas, which, in terms of wingspan, could compete with a modern fighter. Standing on the ground with folded wings, he was as tall as a giraffe. Later, such fossils were found on other continents. Habib, on the basis of calculations, claims that such giant flying reptiles could travel up to 16 thousand kilometers without landing.

According to the estimates of the paleontologist, this "aircraft" weighed almost 300 kilograms, and for the flight from Texas to Europe or Australia, he lightened 70 kilograms, spending spare fat. Nowadays, some small birds make even longer flights, almost from pole to pole, and lose about half their weight.
