Who tried to put on chickens in poultry farms red lenses?

Modern poultry farms are faced with the problem of the aggressiveness of hens, up to the birds pecking their relatives. Traditionally, to prevent this, the tips of the beaks are cut off. Red lighting also helps to reduce aggressiveness, but it is too dim for factory workers. In the 1980s, the American company AnimaLens offered farmers red contact lenses for chickens, which not only reduced their aggressiveness, but also increased laying productivity. However, the novelty did not take root, as it quickly led to a complete loss of vision in laying hens.

Random interesting fact from the Great Encyclopedia:

What is the purpose of daylight saving time?

Imagine that we get up at 7:00 in the morning and fall asleep at 23:00. Arriving home from work at about 18:30, we have dinner and are free after 20:00. It is already dark to go outside and rest. There is no time at all to enjoy a summer day.

Now imagine that we have moved the clock forward by one hour. A person does everything at the same time - but now, when he goes out in the evening at 20:00, there is still enough daylight time to relax. He "won" an hour of daylight!

Of course, daylight saving time does not add hours to the day. This is impossible. This is done in order to increase the number of hours during daylight hours, when the sun rises very early.

Summer time is especially convenient for city dwellers. It allows you to close shops, offices, factories at the end of the working day, when the sun is still high enough. Farmers and peasants who work by the sun usually do not switch to daylight saving time. They cannot work in the field until the morning dew has dried up or after it appears in the evening.

Do you know who invented daylight saving time?

Benjamin Franklin! In the XNUMXth century, while in France, he proposed this innovation to the Parisians, but they did not accept it.

Daylight Savings Time was first adopted during the First World War. At that time, there was not enough fuel to produce electricity, so it was necessary to save it. With the adoption of daylight saving time, many go to bed immediately after dark, while without it, if they had to stay awake until that time, it would be necessary to use electricity.

In 1915, Germany was the first to adopt daylight saving time, in 1916 it was done in England, in the USA - in 1918.

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 ... >>

Autonomous Volkswagen stations for quick charging of electric vehicles 15.02.2020

Volkswagen Group Components and Germany's largest energy company E.ON have unveiled a new prototype electric vehicle charger. This solution will expand the deployment of charging stations.

The solution turned out to be very simple. A new type of charging station charges the electric vehicle from an integrated battery, and not from the network. This eliminates the need for potentially expensive infrastructure and hardware when installing a charging station.

The fast charging system can simultaneously charge two electric vehicles with up to 150 kW, providing an additional mileage of about 200 km on average in just 15 minutes.

Replenishment of the battery capacity of the station is made by connecting to a mains socket with a rated current of 16-63 A. In other words, such charging stations can be installed anywhere where there is this type of connection, for example, near industrial areas, buildings such as schools and hospitals, as well as large residential complexes.
