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 ... >>

Palette Cube accurately detects colors 02.09.2015

Palette has released a miniature Cube device that allows you to accurately determine the colors of real objects. To do this, just put the Palette Cube on the surface of the object, and touch the touch button. The data will be stored in the "cube" memory (up to 20 results) or transferred to a mobile device connected via USB or Bluetooth.

According to the manufacturer, the device will be useful to artists and photographers, who can accurately reproduce the color of an object on its computer image.

In addition to color detection, Palette Cube can measure saturation and color temperature. Measurement results can be presented in RGB, CMYK, HEX, LAB and LRV formats. The scope of delivery includes the Cube Link application, which allows you to import the measured values into the Photoshop graphics editor.

The manufacturer stipulates that liquids, metal, fluorescent and some other surfaces may be difficult, but the "cube" copes well with most other materials.

Dimensions Palette Cube - 50 x 50 x 55 mm, weight - 50 g. Without recharging the battery, it works up to 15 hours (7000 measurements), and in standby mode can be up to three months.

The device costs $180.
