Chalk to protect the file. Tips for the home master

Builder, home master

When processing soft metal (or plastic, wood) with a file, particles of the cut material get stuck in its notches, which are not easy to get rid of later.

This will not happen if you first rub the tool with chalk or charcoal.

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 ... >>

A new method of photosynthesis will help solve the problem of hunger 16.08.2017

Despite the opponents of GMO technologies and synthetic food, scientists have already created meat that is literally grown in a test tube. And it's already on the market. And researchers at the University of Illinois have modified plant photosynthesis to increase yields with less water and fertilizer.

So far, experiments are underway with tobacco, its growth has been accelerated by 20%. Next in line are other agricultural crops. As noted, this will help defeat hunger on the planet.

Modified tobacco seeds process sunlight and carbon dioxide better, which results in a larger yield. As noted, in order to solve the problem of hunger on the planet, by 2050, worldwide yields must increase by 50%.

Funding for the project comes from the Bill & Melinda Gates Foundation, although it has not yet been announced when the modified crops will hit the market.
