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 Sony to release zoom TV
24.11.2004
Sony Corporation has developed a computer chip that allows you to zoom in on any part of the television picture to see in more detail, for example, your favorite football player or named guest on a surveillance camera recording without losing image clarity.
The zoom feature is implemented in a new line of Sony TVs, which will go on sale in the US this month, and in Japan - in November this year. However, in order to use the new chip, it is not at all necessary to buy a new TV - you can purchase a separate set-top box that allows you not only to enlarge the picture, but also to improve the quality of a regular television signal, endowing it with high definition.
The developers noted that although the set-top box with the implemented zoom function can be sold separately, the date of its release to the market and the price have not yet been determined. The new technology is called Digital Reality Creation Multifunction v2. It was demonstrated in Tokyo on September 8 on a regular TV using a special attachment that allows you to select a part of the picture to zoom in and adjust the zoom level.
The demonstration showed panoramic footage of a wide area. The image remained quite clear even when individual fragments were enlarged. It turned out, for example, that a tiny dot in the picture is a walking person, and a dark spot on the body of the river is a hippopotamus.
According to Sony representatives, the second version of the Digital Reality Creation chip brings the image closer in an unusual way - by stretching the vertical and horizontal scan lines, but makes it possible to get clear enlarged pictures due to digital aperture correction of the signal.
