Comments on the article
The use of a DC / DC converter made it possible to abandon the winding of an additional winding in the supply transformer of a self-made satellite receiver. The circuit consists of a multivibrator, a push-pull (!) rectifier with voltage doubling and a stabilizer at the output.
The voltage of the push-pull rectifier, adding up with the supply voltage, provides a sufficient voltage margin (15 + 2 * 15 = 45V) for the stabilizer to work. I supplied power to this converter from a stabilized source of +15 volts, to ensure the high quality of the voltage supplying the varicap circuits.

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 Seizure Implant
10.09.2018
Modern advances in pharmacology help control seizures, but drugs can cause side effects and may also be completely useless if a person is not susceptible to drugs. A neurotransmitter implant placed in the brain to prevent seizures could make a difference, according to new research.
The experimental implant was developed in collaboration between the University of Cambridge and INSERM (French National Institute for Health and Medical Research).
Typically, seizures occur when neurons start firing in a particular area of the brain, causing neighboring neurons to do the same. This behavior of neurons quickly causes a chain reaction, which ultimately leads to a short-term impossibility of full control of one's own body or loss of consciousness.
The device contains a natural neurotransmitter that stops neurons before they fire, and the implant uses electrodes to detect a neural signal associated with a seizure. The difficulty is that a seizure can appear in any area of the brain, respectively, the implant should be placed where the neurons most often provoke seizures.
When a signal is detected, the device activates a built-in ion pump, in which an electrical field is used to push a small amount of the neurotransmitter across the ion reaction membrane and into adjacent brain tissue. So it stops unwanted neural activity.
In tests carried out on muscles suffering from epilepsy, the implant has been shown to be effective in preventing seizures. Also, each time the implant was activated, it needed to distribute less than 1 percent of the neurotransmitter payload, which means that the drug consumption is small and there will be no need to change the implant often. The distributed neurotransmitter was harmlessly absorbed by the brain through natural processes within a couple of minutes, reducing the potential for side effects.
