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 ... >>
| Random news from the Archive Plastic in the air
30.04.2019
We are used to hearing about plastic in the ocean - it is found even at the bottom, and there will soon be more of it in the seas than fish. The earth is also littered with plastic - everyone has seen plastic bottles under their feet. However, plastic particles are not only on the ground and in the water, they are also in the air.
Researchers from the French National Center for Scientific Research, the University of Orleans and other scientific centers in France and Great Britain, using special equipment, collected everything that the winds brought to the weather station in the Pyrenees; Samples were taken monthly from November 2017 to March 2018. On average, 365 plastic microparticles per day settled per square meter - about the same as can be collected in Paris. But the size and composition of the particles were different than the particles in the cities.
Previous studies have shown that in urban air, plastic appears as tiny PET or polypropylene threads over 100 micrometers in length - and they most likely come from clothing and other textile products. Those particles that were caught in the Pyrenees were less than 25 micrometers in length and were fragments of polystyrene or polyethylene - that is, they came off, apparently, from some kind of packaging material.
Although the specific source of the plastic could not be determined, data on the direction and strength of the wind that blew here during the observation period led to the conclusion that the particles flew at least 95 km to the weather station. However, there are no particularly populated areas at such a distance from the station, so the plastic has obviously come a long way.
