Comments on the article

I propose a rectifier circuit for two voltages. In the position of the switch SA1 indicated in Fig. 1, capacitors of the same capacity C1 and C2 are connected in parallel with the output of the rectifier, and the device in this case operates as a conventional bridge rectifier. In another position of the switch SA1, the capacitors are connected in series, and alternating voltage is supplied to the point of their connection, i.e. the rectifier will operate at double the voltage.

Dual voltage rectifier

Figure 2 shows a diagram of an audible alarm made on one NAND element of the K176LA7 or K561LA7 microcircuit. The resistance of resistor R1 is selected according to the maximum sound volume, and the resistance of resistor R2 determines the reliability of starting the generator.

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 ... >>

Corn has a brain 08.03.2010

Back in the XNUMXth century, physiologists discovered that when a fly lands on a sundew leaf, an electrical signal arises in the leaf, causing it to fold, capture and digest the insect. Later, biocurrents were found in other plants.

Italian botanists recently discovered that there is a zone at the tip of the corn root where electrical impulses occur constantly, and in neighboring cells they are coordinated with each other. In a figurative sense, the discoverers even talk about the "brain" of corn. The electrical activity of this site controls the growth of the root.
