Where do bacteria live?

Bacteria are the most common form of life on Earth. These are microorganisms, they can only be seen under a microscope. A bacterium consists of only one cell and has the properties of both animals and plants. There are at least two thousand species of bacteria, and they live everywhere. They live in the mouth, nose, intestines of all living beings, including humans. Others live in fallen leaves, dead trees, the remains of dead animals and skeletons.

Bacteria live in fresh and salt water, milk and most foods. They are found in dust, soil, wastewater. Some bacteria use substances such as gaseous hydrogen, nitrogen, iron, paraffin as food. Other bacteria produce acids or gases that are poisonous to humans. Although most bacteria are killed at very high temperatures, some live in hot environments. Freezing may stop the growth of bacteria, but will not completely kill them. They will just be inactive for a while.

Found bacteria in frozen, salt deposits, which are hundreds of millions of years old. These bacteria in their study came to life. Since bacteria survive in almost any environment, does this mean that a person is under constant threat from them? Fortunately, most bacteria are either harmless or even beneficial to other life forms. Bacteria contribute to the decomposition of dead plants and animals.

Bacteria play an important role in the digestive process of humans and animals. They are associated with food and support human life. Bacteria are essential for fermentation in the production of certain foods, beverages, and some industrial products.

When did the first mailbox appear?

The first mailbox in Europe, that is, one in which a letter could be dropped, knowing that it would be delivered to the addressee, appeared in Prussia in 1824. Prior to this, the sender himself had to take it to the postal department.

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 ... >>

Plastic material with the strength of aluminum 29.10.2021

LG Chem has begun supplying a plastic material to replace aluminum in the manufacture of solar panel frames. Thus, the company intends to enter a new market for itself and promises to solve a lot of problems in solar energy. For example, lightweight panels will reduce the cost of transportation and installation, as well as allow solar farms to be deployed on rooftops that do not have the safety margin to support modern panels.

The plastic material LG Chem LUPOY EU5201 for frames of photopanels is based on polycarbonate. It is noteworthy that for the manufacture of material for frames, you can use polycarbonate chips obtained after the disposal of appropriate building materials.

Moreover, the company promises to develop a technology to collect and recycle plastic solar panel frames for recycling. This is a well-known problem of renewable energy - the impossibility or economic inexpediency of processing photo panels and wind turbine blades. If LG Chem solves this problem for the proposed material, then "green" energy will come a little closer to its ideal of being completely environmentally friendly.

In addition to high strength - like aluminum - the new plastic material is twice as light as aluminum, has a low coefficient of thermal expansion, is fireproof and resistant to ultraviolet, temperature and other climatic influences, which guarantees a long service life of plastic frames without changing the shape and quality of the material. LG Chem is so confident in the new plastic's superior properties that it hopes to pave the way for it into the field of mechanical engineering, for the manufacture of car body parts.
