Which country is the largest in South America?

Brazil is the fifth largest country in the world after Russia, China, Canada and the United States. It occupies almost half of the entire continent of South America.

The Portuguese expedition of Pedro Cabral was the first to set foot on the soil of Brazil. The Portuguese were looking for new routes to India, but they discovered an unknown land, which they called the "Land of the Holy Cross". So Portugal had a new colony.

The Portuguese dreamed of piles of gold and precious stones. However, their search was unsuccessful. The most valuable, according to the Portuguese settlers, in the new colony was the pau brazil tree, from which bright red paint was obtained. The country was named after him - Brazil. Most (about 60%) of the territory of Brazil is covered with tropical forests, which in South America are called selva. Selva covers the entire vast valley of the Amazon River and its tributaries. This dense, impenetrable thicket is also called the "lungs of the planet": it replenishes oxygen reserves in the Earth's atmosphere.

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 ... >>

Light from the sewers 08.06.2006

Six UK wastewater treatment plants use the biogas generated from the biological processing of waste to generate electricity.

The gas released as a result of the assimilation of organic matter from waste by microorganisms consists of 62% methane. It is burned to generate electricity, and the heat generated during combustion is used to dry liquid decay waste - a powdered organic fertilizer is obtained.

Six cleaning stations produce 12 million kilowatt-hours of electricity per year, which is partly used for the needs of the stations themselves, and partly goes to the general network. Three more such stations will soon also be equipped with equipment for capturing and using biogas.
