Since the trances from Lundal never arrived - so far in the variant with capacitive coupling. 4P1L (powered through a stabilovolt) + Pushpool on 4P1L + Pushpool on 6S4S. Iron ZS, then we'll see.

But that is already in the past. I took one lamp and replaced it with an interstage! Fundamentally, the sound has not changed, but the sensitivity has increased, which is clearly insufficient in the previous version. The trance band in this inclusion is modest, from 30 Hz, but with my crooked speakers (45 Hz port) it even helps out.

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 Collective intelligence in insects
29.07.2022
Scientists from Rockefeller University have found that ant colonies behave in the same way as neural networks during decision making. This was done using a new method of analysis, writes sciencedaily.com.
Two researchers, Daniel Kronauer and Asaf Gal, set up an experimental setup to analyze decision making in ant colonies. They tested how the insects would behave in an extreme temperature increase for them.
When each individual ant in the group feels hot underneath, it holds on as usual until the entire colony suddenly changes course. "They run out as one," the scientists say. "It's almost as if they had a large collective mind."
The data obtained during the experiment indicate that the ants combine sensory information with the parameters of their entire group. So they make one decision at all. This process is similar to neural computing, leading to decision making in the same way.
"We first looked at ant colonies as a cognitive-like system," says Kronauer. "This is one of the first steps to understanding how insect communities participate in collective decisions."
