Focus Description:

The initial rectangles of size 3 x 8 and 5 x 8 units, being attached to each other, form a regular chessboard of 8 x 8 cells. These rectangles are cut into pieces, which, after redistribution, form a new large rectangle with an apparent area increase of one square unit:

Focus Paradox with square

Focus secret:

With a careful construction of a drawing of a square, a strict diagonal of a large rectangle does not work. Instead, a diamond-shaped figure appears, so elongated that its sides seem to almost merge. On the other hand, if you carefully draw the diagonal of the large rectangle, the height of the upper of the two rectangles that make up the square will be slightly larger than it should be, and the lower rectangle will be slightly wider.

The inaccurate closure of the parts of the figure in the second method of cutting is more striking than the inaccuracies along the diagonal in the first; so the first way is preferable.

Inside the cells, dissected by the diagonal, you can draw circles, physiognomies, or some kind of figures; when rearranging the component parts of the rectangles of these figures, one more or one less will become.

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 ... >>

Oxygen stops aging 26.11.2020

Hyperbaric oxygen therapy is used for decompression sickness, carbon monoxide poisoning, injuries that led to severe blood loss, burns, and severe infections (although its effectiveness has not yet been confirmed in all cases). The essence of the procedure is that the patient is in a chamber (pressure chamber) with a pressure that is higher than normal atmospheric pressure. Under such conditions, the blood is better saturated with oxygen - it is carried not only by erythrocytes, but also to a large extent by blood plasma.

Researchers at Tel Aviv University have found that telomeres lengthen in human immune cells after hyperbaric oxygen therapy. So called end sections of chromosomes, in which no genetic information is encoded. Their job is to protect the rest of the chromosome from damage. Telomeres shorten over time, and the shorter it is, the greater the likelihood of various age-related anomalies. Therefore, they are called one of the indicators of aging.

On the other hand, cells have an enzyme that can lengthen telomeres, but this enzyme is usually inactive. Saturation of the blood with oxygen, apparently, somehow activates it. The experiments were carried out with 35 volunteers over 64 years of age - within three months they underwent 60 sessions of hyperbaric oxygen therapy. As a result, telomeres in immune blood cells lengthened by 20-38%. That is, oxygenation not only stopped aging, but also reversed it - at least in these cells.

In the blood, the proportion of aged cells decreased by 11-37%. We have already talked about such cells: despite all the aging processes, the program of cellular self-destruction does not turn on in them, as it should be in the norm. As a result, the cell, having grown old, continues to live and age even deeper, and at the same time it releases various substances that spoil the life of other cells. Animal experiments have shown that if the body is cleansed of aged cells, it prevents some age-related diseases and prolongs life.

A lot depends on our immune system. Perhaps with the help of hyperbaric oxygen therapy, which rejuvenates it, we will be able to do what we do with mice: delay age-related diseases and increase life expectancy. Although all the same, sooner or later it is necessary to find out the mechanism that links rejuvenation with an increased level of oxygen in the blood.
