Knots have long been used for various purposes, not only in maritime affairs, but also in medicine. They are still used by surgeons to tie threads of ligatures to stop bleeding and to stitch tissues and skin together. Nowadays, medicine has not yet abandoned the use of knots, and doctors skillfully use them.

During abdominal operations, surgeons have to suture catgut (a special material obtained from the mucous layer of the intestines of a ram or sheep), which resolves after 3-4 weeks. When tying, the catgut slides, and, making knots on it, surgeons use special clamps.

During microsurgical operations, doctors use extremely thin suture material - a synthetic thread 10-200 times thinner than a human hair. It is possible to tie such a thread only with the help of special clamps under an operating microscope. These threads are used in the suturing of the walls of blood vessels, for example, in the replantation of fingers, in the suturing of individual nerve fibers. Mainly used womanish, straight, bleached, surgical nodes and the so-called node "constrictor".

When tying surgical node first, two half-knots are made one after the other with two ends, which are then pulled in different directions. Then they tie from above, but in the other direction, another half-knot. The result is a knot very similar to a straight knot. The principle of the knot is that the first two half-knots do not allow the two ends to disperse in different directions while another half-knot is knitted on top.

It is convenient to use this knot when there is a need to pull off and tie some elastic bale or load with a rope, and the tightened first half of the knot on the rope, without releasing its ends with your hands, you have to press it with your knee.

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 ... >>

Smart scales determine the speed of propagation of the pulse wave 11.06.2016

Withings introduced the Body Cardio smart scale. The device is distinguished by the ability to determine the body mass index, as well as the percentage of fat, muscle and bone mass. Moreover, the scales are able to monitor the state of the cardiovascular system. In this case, we mean the ability of the scale to determine the heart rate, as well as the presence of Pulse Wave Velocity technology, which is responsible for determining the rate of propagation of the pulse wave (PVW).

Thus, the Body Cardio scales allow you not only to track weight and progress during sports, but also to monitor your health. Of course, the device is able to detect which family members have stepped on the scale and send the data to the corresponding paired device. The small scale display, when connected to a wireless network, can even show weather data. The capacity of the built-in battery is enough for a year of work.

The owner of Body Cardio may consent to the anonymous sending of his data to medical professionals.

The novelty will be available in early July for $180. At a price of $130, it will be possible to purchase a modification without PVW detection technology.
