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 ... >>

PVC tiles and linoleum are dangerous for asthmatics 02.11.2013

Children who sleep in a room with PVC flooring are more likely to develop asthma than children who do not have the material in their rooms. In addition, there is speculation that PVC covering in the parents' bedroom also provokes the development of asthma in unborn children, which indicates exposure to PVC during the prenatal period.

Soft polyvinyl chloride (PVC) is a common material - it is linoleum and PVC tiles that imitate various materials, including natural wood. Outwardly, such material looks attractive, and it is unpretentious in care, which made it very popular among consumers.

But Swedish researchers aren't thrilled about PVC flooring. They believe soft PVC contains phthalates, which are commonly released into the environment. Chemicals from the phthalates group, according to scientists, can provoke endocrine disorders that affect the development of several chronic diseases, such as asthma and allergies.

Swedish scientists conducted a multi-year experiment to determine how PVC coating affects the development of asthma and related disorders. The study began in 2000 and involved more than 14 children aged 000-1 years (at the start of the experiment).

The basic questionnaire contained questions about family health, lifestyle, characteristics of the house or apartment, etc. The scientists conducted control surveys in 2005 and 2010, that is, they traced the dynamics of the development of diseases. The researchers paid the greatest interest in the further study to children who developed asthma and other allergic diseases during the observation period.

The analysis showed that children who had PVC flooring in their bedrooms were more likely to develop asthma - asthma was usually diagnosed by doctors in the first 10 years of life. The incidence of asthma among children who did not have PVC flooring in their bedrooms was much less common. According to scientists, in some cases, the risk of developing allergies and asthma more than doubled.

Scientists have also found evidence that PVC floors in parents' bedrooms also contribute to the development of asthma in unborn children. According to the researchers, this is a sign that the PVC coating affects the baby in the womb.

This study is not the only one that speaks about the unsafety of PVC, more precisely, the phthalates emitted by it. Thus, a previous study showed that PVC materials in the house are dangerous for children aged 2-6 months - phthalates (butylbenzyl phthalate, BBzP) accumulate in their bodies. Scientists point out that people themselves can reduce the risk of developing asthma and allergies in their children, simply by abandoning the PVC coating.
