Which sea is the most salty?

On average, the water of the oceans and seas of the Earth contains 3,5% salt. In the Red Sea - 4,1%, in the Mediterranean - 3,7%, in the Adriatic - 3,6%, in the Baltic less than - 1%, in the Black Sea - 1,8%, in the Sea of Azov - 1,1%. In the Dead Sea, on average, salt is 27% (by volume), but sometimes it reaches up to 31%. True, this is not a sea at all, but a closed lake. It is difficult to swim in it, it is almost impossible to dive.

Why don't all trees have growth rings?

It is widely known that the age of a tree can be determined by the growth rings on the cut, the appearance of which is due to the change of seasons and the accompanying acceleration or deceleration of the growth of tree tissues. But this phenomenon is valid only for plants of the temperate zone. In tropical regions, where the climate is approximately the same throughout the year and there are no clearly defined periods of cooling or drought, most trees do not form visible annual rings. To find out their age, it is necessary to analyze the concentration of certain chemical elements in the wood.

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 ... >>

Found a way to increase the efficiency of solar power plants 11.07.2022

Scientists from Stanford University in the USA have developed a cheap lens for solar panels that can collect up to 90% of the light and increase its brightness by 3 times. Passive Axially Graded Index Lenses (AGILE) photocell technology can help reduce the footprint of solar power plants.

Solar energy will play an important role in meeting sustainable future energy needs. The technology could help install solar panels in small areas where it was not possible before.

AGILE does not require solar tracking and respects the maximum limit of the cosine projection by concentrating light falling on it from all angles.

With AGILE, pointless concentration systems (i.e. without having to follow the Sun) can be used, which reduces the amount of photovoltaic material and also effectively absorbs stray light. After all, the scattering of light due to cloud cover and the atmosphere can reach 20% even on a sunny day.

The AGILE concept The AGILE concentrator matrix system consists of a repeating block that absorbs all incident light and therefore appears dark. This graded index immersion optics can also be applied in areas such as light control in solid state lighting, laser connectors, display technology, etc.

The scientists used strong, broadband transparent and inexpensive sorted materials for two AGILE prototypes: a glass pyramid made by stacking different glass plates and an overlapping polymer array of cones.
