How do you get a tan?

Many of us do not even realize how useful the light of the sun is for people. For example, it kills fungi and bacteria that parasitize our skin. Under the influence of sunlight, the skin produces a substance that constricts blood vessels and thus increases blood pressure. The ultraviolet rays of the sun produce the vitamin in our body. D.

One of the effects that sunlight has on the skin is what we call sunburn. There is a substance in the skin called histidine. The ultraviolet rays of the sun turn it into a substance that can dilate blood vessels, causing reddening of the skin. And how is formed what we call sunburn?

There is also a substance in the skin called tyrosine. Ultraviolet rays act on it and turn melanin into a dark pigment, which is deposited on the surface layers of the skin and gives it a reddish-brown color. Melanin also protects the body from further exposure to sunlight. Since sunlight has such a variety of effects on the skin and human body, one should be careful when taking "sunbathing".

Did you know that even exposing the sun to the sun alone can increase blood pressure, enrich the bones of the body with vitamin D and so on? Most people take these things lightly, but the greatest benefits can be obtained from sunbathing if you follow the principle of gradualness. This means that on the first day you can expose one fifth of your body to the sun for five minutes, on the next day another fifth of your body for ten minutes, and so on.

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 ... >>

Hywind Tampen, world's largest floating wind farm, launched 13.11.2022

Norwegian energy company Equinor, better known for projects in the oil and gas industry, has begun commissioning the world's largest (according to it) floating wind farm, with more turbines to start operating at the end of the current beginning of next years.

The first turbine under the Hywind Tampen project started operating on Sunday. Although this is renewable energy, all electricity produced will be used exclusively to obtain oil and gas from the North Sea sites.

Hywind Tampen is located 140 km off the coast of Norway, seven turbines should be operational by the end of 2022, and four more should be installed next year. After the full implementation of the project, its capacity will be 88 MW.

In addition to Equinor, Var Energi, INPEX Idemitsu, Petoro, Wintershall Dea and OMV are participating in the project. According to reports, Hywind Tampen will provide up to 35% of the energy for the Gullfaks and Snorre oil and gas developments. The use of renewable energy will reduce the carbon footprint of fossil fuel extraction. However, such a project still draws criticism from eco-activists, since hydrocarbons, as a result, make the main contribution to environmental pollution.

In 2017, Equinor already launched the Hywind Scotland project, a 30MW five-turbine power plant that Equinor calls the world's first floating wind farm.

Since then, the number of such solutions has increased significantly. Projects from Scotland to the US to China are at various stages of implementation. It is known that only the United States intends to prove the total amount of energy supplied by floating wind farms to 15 GW by 2035. In addition, the country plans to reduce the cost of such power plants by more than 70%.
