Comments on the article

To prepare casein glue, take cottage cheese (casein) and gradually add it to a saturated solution of borax until the cottage cheese no longer dissolves. You will get a thick transparent liquid with high adhesiveness, suitable for sticking labels, postage stamps, etc.

Before sticking, the object should be slightly moistened.

By adding a few drops of Schering's liquid formalin to this glue, you can make it long-lasting.

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 ... >>

New Solid State Relays International Rectifier 16.06.2007

Compared to its peers and predecessors, the PVN012A family has half the AC on-state resistance (Rdd(on)) and 37,5% higher AC load capacity at 100% duty cycle.

The new relay series is also rated for the maximum impulse (overload) current. With low channel resistance and high current carrying capacity combined with a compact housing, the PVN012A relays outperform traditional electromechanical relays.

They occupy a smaller area, are rated for high isolation voltage between input and output, have a stable open resistance throughout the entire service life, high sensitivity and high reliability, and are free from contact bounce.

The new relays are rated for 20 V, with an on-state resistance of 50 mΩ AC and 15 mΩ DC. The current carrying capacity is 4 A AC and 6 A DC. The insulation test voltage between input and output is 4000 V. The new relays are available in lead-free 6-pin DIP and SOIC packages and on tape.
