Recently, acupuncture has become widespread. But the specific location of active points is difficult to determine even from an atlas, since a point on the skin surface has a size of about 1 sq. mm.
The node for searching for active points is made on three transistors VT1 ... VT3 and a LED VD1. The point search principle is based on the fact that the skin resistance above the active point is several times lower than the average human skin resistance. The search circuit is a comparator amplifier. When the electrode hits the active point, the LED lights up and a slight tingling sensation is felt. Switch S1 changes the polarity of the impact on the point by the current, which inhibits or excites the nerve channel. Switch S2 connects a low-frequency pulse generator made on a DD1 chip.
The device has the dimensions of a toothbrush case with a search electrode in the form of a rounded needle with a diameter of 1 mm. The second electrode ("mass") is made from a segment of a telescopic antenna and is connected to the device through a wire about a meter long. When searching for an active point, this electrode is clamped in the hand. Switches S1, S2 are made of paired microswitches. Two knobs of variable resistors are installed on the body of the device: R2 - "impact current" and R8 - impact frequency", with a graduated scale. The Krona battery is used as a power source. To check the device in the "search" mode, set the maximum exposure current and close electrode. At the same time, the LED should light up.
Below is a list of literature on reflexology.
It is not recommended to use the device without consulting a doctor.

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 ... >>
| Random news from the Archive Language influences thinking from infancy
02.08.2016
Usually we think that language only reflects the features of our vision, our thoughts and feelings. But can language itself influence our thinking?
The question arises at what age the influence of language on thinking first manifests itself. And, it would seem, the answer suggests itself that this happens in childhood, when the child learns to speak. Researchers from Northwestern University agree with this point of view, but with one caveat - according to their data, language begins to influence consciousness even before a person pronounces his first word.
Nine-month-olds, who were not yet able to speak, were shown brightly colored creatures that, appearing randomly in the middle of the screen, ran either to the left or right, and then disappeared. The essence of the experiment was that the "population" of beings was designated either by one word or by two words, and in the latter case one word was intended for those who move in one direction, and the other for those who move in the other direction. These words were heard by the children watching the creatures.
Then came the turn of the second part of the experiment: multi-colored creatures again appeared in the center of the screen, and psychologists carefully watched with the help of special equipment, where the children would look. In the direction of the child's gaze, one could understand what he expected from the creature - that it would move to the left or to the right. The point here was to understand whether there was a connection between the verbal categories denoting "right" beings and "left" beings, and thinking. The connection really appeared: those children who learned two categories predicted the movement of the figures quite well; but those who heard only one name common to all, could not predict the direction of movement.
It follows that even in the process of initial language acquisition and even before a person himself learns to speak, language categories affect both our perception and the ability to work and analyze what we managed to perceive.
