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 Cold computer memory
27.12.2012
Researchers at the University of California School of Engineering and Applied Sciences have made significant improvements, significantly advancing the ultra-fast, high-bandwidth computer memory class. This type is called magnetoresistive random access memory or MRAM.
The team called their new development MeRAM. It has great potential for use in almost all electronic devices - smartphones, tablets, computers, microprocessors. You can also use it to store data. MeRAM's key advantage over other technologies is its combination of low power consumption, high read and write speeds, and non-volatility - the ability to retain data in the event of a sudden power outage.
Currently, magnetic memory is made on the basis of technology using the spin of electrons, and not just their charges. This technology (SST) uses electrical current to write data to memory. It outperforms other technologies in many ways, but it requires a certain amount of power, and quite a lot of it, and therefore generates heat when recording. In addition, the volume of such memory is limited by the currents required to record information per unit area.
In the case of MeRAM, the scientists replaced current, which plays a key role in SST, with voltage. This eliminates the need to transfer huge amounts of electrons through wires, and instead uses electrical potential differences to switch magnetic bits and record information. As a result, the computer generates much less heat, making it up to 1000 times more energy efficient. And the memory itself can be 5 times denser - more information is stored in the same physical area, which reduces the cost of transferring a bit.
"The ability to switch nanosized magnets using voltage is an important and rapidly growing area of research in magnetism," said electrical scientist Pedram Khalili, project leader at UCLA. how the devices will operate without the need for an external magnetic field and how to integrate them into high-density memory arrays".
