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 ... >>

Sapphire razor 24.11.2015

The fashion for a beard seems to have been established in earnest and for a long time. Nevertheless, manufacturers of various shaving devices are well aware that fashion comes and goes, and hair grows, and something needs to be done about it. But how to surprise buyers? For example, an iridium handle and a sapphire blade.

A few years ago, the American startup Zaffiro, hatched from the Bright Light Ventures innovation incubator in Portland, Oregon, announced the creation of a sapphire blade, which, according to the company, took 8 years of effort by rocket engine specialists , nanotechnology and particle physics. Thanks to these efforts, it was possible to create sapphire blades with an edge thickness of 80 atoms. These blades are 10 times sharper than a surgical scalpel and 5000 times thinner than a human hair. Since sapphire is second only to diamond in hardness, the resulting blades last between 6 and 12 months.

The first versions of the razor were sold at prices ranging from $18000 with a gold handle to $100000 with an iridium handle. The party was, of course, limited - mainly by price. The current generation Zaffiro, called the Z2, will sell for $299 and the cartridge for $49, thanks to a reduction in the cost of farmed white sapphire, widely used in iPhone lenses and other electronic devices.

In the future, the company promises that the blades will last five times longer. True, the issue with the notorious handle has not yet been resolved. The company's engineers suggest that it will be made of surgical stainless steel with titanium or molybdenum inserts.

I assembled the indicated circuit on N4004 diodes and something felt in the circuit, not that I put 4004, they immediately start to warm up when power is applied and did not work HL5-6 removed VD6 - WORKED!
