Coloring varnishes and varnishes produced exclusively with the help of resin dyes.

The coloring matter is dissolved in alcohol and added to the painted varnish. The dissolution of the coloring matter is carried out in an enameled or glass container, where a little alcohol is added, mixed and dissolved by heating in a water bath. The resulting solution is then filtered through a thin cloth.

In view of the fact that it is sometimes necessary to take quite a lot of dye solution in order to give the varnish a proper defined shade, it is advisable to use a thick varnish, otherwise a very dilute varnish solution is obtained.

For black color use a mixture of log extract with two-chromopotassium salt. For cheaper varnishes, lamp black or asphalt is used.

To get yellow and brown polishes use turmeric, gummigut and various varieties of shellac.

To get red resort to dragon blood.

purple lacquer obtained by adding sandalwood.

golden lacquer can be obtained by mixing a solution of shellac in strong alcohol with such an amount of a saturated solution of picric acid until the finely induced solution is golden in color.

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 ... >>

The weakening of the immunity of astronauts will be predicted 13.03.2012

NASA scientists have developed technology that can detect weakened immunity in advance and protect astronauts from a number of unpleasant infectious diseases. New diagnostic technology could also be useful on Earth - it will shorten the duration of illnesses and reduce the side effects of treatment and the risk of complications. Physiological, emotional and psychological stress associated with space flight and other complex activities can lead to a weakened immune system and the activation of viruses, such as herpes, which leads to damage to the skin and internal organs.

Astronauts are in almost perfect isolation from human society and therefore infectious epidemics do not threaten them. However, NASA scientists are concerned about how the immune system will function during future long-duration deep space missions. Therefore, experts decided to develop a test to assess the state of the human immune system. Choosing one or more biomarkers that show the effectiveness of the immune system in healthy people is a very difficult task. However, the herpes virus can become such a marker, which helps to make an early diagnosis of changes in the immune system. There can be eight types of herpes virus in the human body, and almost all people are infected with one or more types of these viruses.

Herpes viruses cause various illnesses, including herpetic fever (herpes simplex virus or HSV), infectious mononucleosis (Epstein-Barr virus or EBV), chickenpox, and shingles (varicella-zoster virus or VZV). In addition, herpes suppresses the immune system and can cause the development of certain types of cancer.
Herpes is present in the blood of at least 95% of the adult population of the Earth, including the blood of astronauts. Thus, measuring the status of herpes viruses in human body fluids is a much needed immune biomarker.

Johnson Space Center researchers have found that four types of the herpes virus can become active and appear in bodily fluids during spaceflight. This happens due to the weakening of cellular immunity: viruses emerge from their latent state and turn into active infectious agents. Replicated viruses enter saliva, urine, or blood and can be detected using the polymerase chain reaction. To detect the activation of herpes, NASA specialists have developed a special test strip, on which a sample of the patient's saliva must be applied. In case of weakened immunity and activation of herpes, the test strip turns red.
