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 strongest material 14.05.2018

Previously it was believed that the strongest material was spider silk, and the best building materials were steel, ceramic and glass.

Even though technology is advancing rapidly, it is difficult for researchers to keep up with nature. Recently, scientists have been trying to replicate the architecture of natural materials at the nanoscale in order to create a more durable material. For example, by studying the strong, rigid cell wall layer of wood, which is made up of cellulose nanofibrils, the researchers tried to create strong macroscopic materials. However, weak adhesion and incompatibility of the components did not allow scientists to realize the idea.

Researchers at the American Chemical Society have tried to overcome these limitations. The team used inkjet technology to perfectly organize the macroscale fibers. Even the weakest fiber they made with this method was stronger than other cellulose nanofibers known before. And most importantly, macroscale fibers were stronger than metal, alloys and fiberglass and eight times stiffer than spider silk dragline, which is the gold standard for the strength of lightweight biopolymers.

Afiget!

Nastya
Super! [;)] [up]

Annie
Nice, but old.

Vetal
Great!

a guest
Funny, interesting.

Igor
Old does not mean useless. Mathematics is also old, but almost everyone studies it, although not everyone loves it. [up] [roll]

a guest
In the word SHADOW, the letters are not parallel!

Maria
I had no idea there were so many illusions. But... The mesh hasn't been repaired. And I checked the letters with a ruler - the difference between the bottom and top is 1 mm.

Alexander
Suite!
