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 ... >>

The lightest 16-inch Schenker Vision 16 and Vision 16 Pro ultrabooks 02.11.2022

Schenker has unveiled the world's lightest 16-inch gaming laptops. In practice, they can be called gaming ultrabooks.

Two models: Vision 16 and Vision 16 Pro. Technically, they differ slightly, and the body is exactly the same, and therefore the thickness is the same - 17,1 mm. Weight varies from 1,4 to 1,6 kg depending on the configuration. That is, in terms of thickness and weight, the 16-inch gaming Vision 16 is comparable to many 14-inch models that do not offer discrete graphics cards at all.

The characteristics of the new items are also very similar. Except for the HDMI connector (the Vision 16 has HDMI 2.0, while the Vision 16 Pro has HDMI 2.1), the difference is only in the graphics subsystem. The base model is available without a discrete graphics card or GeForce RTX 3050 Ti. For seniors, RTX 3060, 3070 Ti or 3080 are available.

The heart is the Core i7-12700H, is from 16 to 64 GB of RAM, SSD from 500 GB, USB-C, Thunderbolt 4 (x2), and an 80 Wh battery. The screen in all cases is characterized by a resolution of 2560x1600 pixels and supports a frame rate of 90 Hz (for the younger model) or 240 Hz (for the older one).

The Vision 16 starts at 1550 euros, while the Vision 16 Pro starts at 1900 euros.
