When replacing the variable resistor R1 (the previous circuit) with a switch, the considered regulator turns into the simplest tone register (position 1-classic, 2-jazz, 3-rock), popular in the 50s-60s and re-used in the equalizers of radio tape recorders and music centers 90s.

Tone register. Scheme

Despite the fact that in the field of tone control, it would seem, everything has long been said, the variety of passive corrective circuits is not limited to the proposed options. Many forgotten circuit solutions are now experiencing a rebirth at a new qualitative level. It is very promising, for example, a volume control with separate loudness control for low and high frequencies.

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

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 ... >>

Natural eco-friendly glue 24.07.2012

Most of the things around us are glued together. Scientists at the Fraunhofer Institute (UMSICHT) see this as a problem, since adhesives are still predominantly made from petroleum feedstocks. Thus, only in Germany in 2010 more than 820 thousand tons of glue were produced. However, adhesives can be made from renewable raw materials such as proteins, natural rubber, starch or cellulose. Researchers at UMSICHT are working to develop new formulas for the adhesive needed to make shoes, cars, airplanes, wind turbine blades, self-adhesive stickers, plaster, and more.

Scientists are developing a new pressure-sensitive adhesive for industrial applications. Such glue is suitable for a lot of household items: patches, adhesive tapes, labels, etc. The requirements for this type of adhesive are quite high: it must retain its properties at room temperature for a long time, stick together at low pressure, but at the same time be easily peeled off surfaces. German researchers have focused on the development of a polylactic acid polymer adhesive. This biological material is inexpensive and is produced on an industrial scale, which in the future will make it possible to abandon the use of oil as a raw material.

However, the properties of lactic acid polymer are fundamentally different from the polymers used today, in particular from polyacrylates and styrene. This means that scientists must develop an entirely new formula for the adhesive. This is quite possible - nature is an example of this. So, the mollusk Dosima fascicularis produces a special glue with which it is attached to the bottom of ships. This superglue is so strong that it is almost impossible to unhook the clam from the boat even with strong solvents. At the same time, it has a special property - it sticks together even under water.

German scientists are trying to create a similar water-dispersion adhesive, the components of which are dissolved in water. Researchers are currently trying to figure out which amino acids make up biological superglue proteins. If successful, it will be possible not only to abandon oil raw materials and improve household items such as adhesive tape, but also create, for example, medical adhesives for closing wounds and “repairing” broken bones.
