The trunk lid was used as a VHF receiver antenna, see "Radio Amateur" 11/96, p. 37 Car body as an antenna. Whoever has not read it, the counterpart of the trunk lock is isolated from the body, with the lid closed, a gap is formed between it and the body from the lock to the canopies in both directions. The bot is the antenna. It works a little worse than the pin installed on the roof, but no ........ (enter the necessary one) spionite. It is better to tune according to the frequency response, although it is also possible according to the GSS with a certain skill, I recommend the band 100-108 MHz. The task is to filter out the excess before the amplifier. In the SB channel, an amplifier is not needed, it only adds noise.

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 US space exploration
08.10.2021
The US Space Force has established an intelligence analysis team at the National Air and Space Intelligence Center at Wright-Patterson Air Force Base, Ohio.
The structure, called the Space Force Intelligence Activity (SFIA), will become an intermediate step towards the creation of a full-fledged Space Intelligence Center.
A memorandum to this effect was signed by Major General Leah Lauderbuck and Lieutenant General Mary O'Brien. Lauderbuck is the head of the Intelligence, Surveillance and Intelligence Service of the Space Force. O'Brien is the USAF Deputy Chief of Staff for Intelligence, Surveillance, and Cyber Effects Operations.
The organization will be staffed by teams of space and counterspace analysts who are based at the National Aerospace Intelligence Center (NASIC) and will move to the National Space Intelligence Center.
NASIC is the Pentagon's primary source of information on threats affecting air and space operations. The space and counterspace analysis groups include both military and civilian personnel.
