Appretura replaces the cream and differs from the latter in that it does not require rubbing with a brush to obtain shine, after spreading it.

black finish

Take 20 parts of shellac, 10 parts of borax to 140 parts of water, heat in a water bath with constant stirring until dissolved, and add 20 parts of sugar, 12 parts of glycerin and 5 parts of aqueous nigrosin. Leather items previously cleaned with soap and water are smeared with a brush or sponge, which are moistened in the dressing.

yellow finish

Take 2 parts of yellow wax, 1 part of stearin, 1 part of linseed oil, melt in a water bath, add 6 parts of turpentine, 1 part of yellow golden ocher. At the same time, 1 part of solid soap is dissolved in 10 parts of water and, with constant stirring, this solution is mixed with the above mixture until a uniform mass is obtained, to which 8 parts of water are gradually added. After cooling the mass, it is filled with bottles with a wide neck.

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 ... >>

Virtual reality as soothing during surgery 23.09.2022

American doctors from the Beth Israel Diaconis Medical Center performed a surgical intervention in which virtual reality was used, which allowed the use of less sedative drugs.

During the study, surgeons performed an operation to treat carpal tunnel syndrome. Usually during the procedure, patients are given the drug propofol, as well as local anesthesia. As a result, patients are under a strong sedative effect of the drug, which makes them sleepy and calm.

However, this method can lead to a drop in blood pressure and narrowing of the upper airways, which increases the risk of stroke, heart attack, or respiratory failure.

For the experiment, the researchers divided 34 subjects into two groups: the first was immersed in virtual reality and used traditional drugs, and the second was given only propofol. In VR glasses, participants could independently choose their surroundings: meadow, forest or mountains.

As a result, patients in the first group, on average, required 260 mg less anesthetic. Also, such operated patients were discharged from the postoperative block approximately 22 minutes earlier.

One month after the intervention, no difference in wrist function was found between the two groups.
