When buying, the elements are checked for integrity (visually, cracks on the elements are far from always visible). A serviceable element must provide on a bright, sunny day, the short-circuit current declared in the passport data. Do not be afraid to short-circuit the elements to check its integrity - nothing will happen to it.

If there is only one damaged cell in a battery composed of several solar cells, the performance of the entire battery deteriorates. The maximum current that a battery, consisting of many cells connected in series, can give is equal to the maximum current of the worst element in its circuit.

It is optimal to use connectors in the form of sockets for outputting battery power.

Sealing the battery not only protects it from moisture, but also from clogging the cells with dust. Severe clogging of the cells can significantly reduce the efficiency of the entire battery.

Attention, important!

Solar cells are very fragile! Special care should be taken when making and installing batteries yourself. In industrial conditions, the elements are soldered with a hot inert gas jet, the elements of the house are assembled using a soldering iron with a thin tip.

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 ... >>

Peaceful creatures turn into predators 16.01.2017

Last fall, the American firm Northrop Grumman announced plans to develop, together with the US Air Force Research Laboratory, a small laser that would be mounted on fighter jets and serve as a "defensive" weapon, i.e. hit attacking missiles, drones and enemy aircraft. Thanks to active focusing, the future system will be able to perform various tasks as needed, including identifying targets and changing the focus of the laser to maintain maximum efficiency when the air is disturbed along the path of the beam.

Recently, scientists at Yale University unexpectedly discovered another possible use for such a laser, although their research has not (yet) been in the field of defense. They studied the predatory instincts of animals using optogenetics, stimulating the activity of neurons through targeted irradiation of cells. So far, this technique has been used, for example, to deliver drugs to deep brain tissues, possibly treat acquired blindness, and to control pain.

In a new experiment, scientists stimulated neurons in the amygdala of a mouse's brain with a laser and found that one of the nerve groups triggered a predatory instinct in the animal, while another turned on the jaw muscles, causing the mice to bite anything and everyone in their path. When the laser was turned on, the mice jumped on the object, grabbed it with their jaws and began to bite intensely as if it were their victim. Moreover, the hungrier the mice were, the more aggressive their behavior was, and they bit absolutely everything they came across - bottle caps, sticks, toys and live insects. However, they did not attack their fellow caged mice, which is quite valuable if this technology is used for the soldiers of the future.
