Who supplies CO2 to the atmosphere?

Most of all - agriculture (39%) due to burning of forests, the use of nitrogen fertilizers, the formation of methane in animal husbandry. Electricity production adds another 29%, transport - 13,1%, building heating - 17,9%.

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 ... >>

Periodic vibrations of an unknown nature found inside neutrons 14.11.2021

Scientists working with China's BEC-II particle accelerator have found evidence that periodic oscillations of an unknown nature exist within neutrons.

The measurements showed that the electromagnetic structure of the neutron changes in a periodic manner. Something similar was previously recorded for protons. Subsequent experiments and theoretical calculations will help us understand how these oscillations arise and what role they play in the structure of nucleons.

Almost all elementary particles are made up of small objects that physicists call quarks and gluons. There are three quarks in protons, neutrons and other "heavy" baryon particles. Their smaller "brothers" - mesons - consist of two similar components, one of which is an antiquark, the basic component of antimatter.

Scientists have long been trying to understand how quarks are distributed inside protons, neutrons and other particles, as well as to study how they interact with each other and with the "sea" of virtual quarks, continuously appearing and disappearing at any point in space. All of these interactions, as scientists suggest, affect the structure of particles, their size, mass and other properties, the results of measurements of which sometimes do not coincide with theoretical predictions.

Physicists led by Professor Yuan Changzheng of the Institute of High Energy Physics (China) discovered an unusual property of neutrons while studying their structure at the BEC-II particle accelerator. Scientists collided beams of electrons and positrons and observed the formation of pairs of neutrons and antineutrons, which periodically arise as a result of the interaction of particles of matter and antimatter. The speed, energy and direction of motion of the neutrons and antineutrons generated by them depend on their internal structure, which was used by physicists for ultra-precise measurements of the distribution of quarks inside these particles.

The researchers have been observing collisions of electrons and positrons for several years, which allowed them to improve the accuracy of measurements of the structure of neutrons by about 60 times compared to previous experiments. The improvement in the quality of the data has revealed a curious phenomenon that physicists have already encountered several years ago when studying the structure of protons.

Back in 2013, scientists working with the BaBar installation discovered evidence that there are some fluctuations inside protons that affect the nature of the charge distribution inside it. The exact nature of this phenomenon is still a mystery to physicists, since the existence of these oscillations is not predicted by any theory describing the interactions of quarks.

Something similar, as Yuan Changzheng and his colleagues found out, occurs inside neutrons, and the oscillations inside them turned out to be opposite in phase compared to their counterpart inside protons. As the scientists hope, subsequent experiments on BES-II and other particle accelerators will help to reveal the nature of these oscillations and understand what role they can play in the behavior of neutrons and protons.
