Comments on the article

In accordance with IEC Publication 62 for inductances, the nominal value of the inductance and the tolerance are coded, i.e. allowable deviation from the specified face value. The most commonly used encoding is 4 or 3 colored rings or dots. The first two marks indicate the value of the nominal inductance in microhenries (µH, uH), the third mark is the multiplier, the fourth is the tolerance. In the case of coding with 3 marks, a tolerance of 20% is implied. The colored ring denoting the first digit of the denomination may be wider than all the others.

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Bloodhounds of mercury 07.06.2000

Sweden trains police dogs to sniff out mercury. A few years ago, the Swedish parliament decided that all old, unwanted stocks of mercury and waste containing this dangerous metal should be neutralized by 2001.

There is a lot of mercury in old manometers, barometers, thermometers, but they are relatively easy to find. It is more difficult to detect mercury in elbow siphons under washstand sinks in dentists (mercury amalgams are used to make dental fillings), as well as under the floor in chemical and other laboratories, where it could accumulate for years from small, randomly falling droplets. It is found by dogs that react to the smell of even one milligram of mercury. Each shepherd checks up to 110 siphons per day.

In two years, two trained shepherd dogs found 10 tons of mercury, of which 1,3 tons were found in schools, where mercury was used relatively recently in demonstration experiments, and even in laboratory work of students. It is assumed that there are still about 40 tons left to be found, mainly in industrial enterprises. In addition, it is necessary to decide where to arrange reliable and safe disposal of mercury.

Norway is about to undertake a similar program to search for mercury with the help of dogs.
