Technique against pirates

18.12.2000

You are mistaken if you think that the pirates remained somewhere in the seventeenth century. In the waters of Southeast Asia, pirate attacks on cargo ships are now quite common. Over the past four years, the number of attacks on Japanese merchant ships has increased fivefold. And all over the world in 1999 there were more than three hundred cases of piracy. It got to the point that the team of the Japanese icebreaker "Sirase", which set off for Antarctica last fall, when passing through the most "pirate-dangerous" zones off the coast of Indonesia, tightly battened down and tied all the doors from the inside with ropes, and water cannons were placed on the deck to wash away those climbing on board of pirates.

The methods of the pirates have remained the same: the ship is boarded by throwing hooks with ropes or rope ladders on board.

In July of this year, 15 Japanese bulk carriers were equipped with a simple protection system. A wire connected to a tension sensor was stretched along the deck railing. When the hook breaks or pulls on the wire, an alarm sounds and powerful spotlights are turned on. But ships are equipped with more sophisticated anti-piracy devices.

An attack is automatically notified by satellite to the Coast Guard and the shipowner, one of which is about the size of a shoe box, and no one on the ship knows where the box is hidden so the pirates can't turn it off.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

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, ... >>

Lawn mower against crime 08.03.2018

Researchers from Columbia University (USA) found that tidying up wastelands in poor areas of the metropolis significantly reduces the level of crime in these areas.

Abandoned plots of land, overgrown with grass and littered with garbage, make up to 15% in US cities, scientists have calculated. Often such wastelands are chosen by criminals for drug trafficking and consumption, for escape and shelter from the police.

Scientists, together with the Pennsylvania Horticultural Society and the Philadelphia Department of Housing, decided to try to clean up these areas and see how such changes would affect the crime rate in nearby areas.

Specialists managed to put in order hundreds of wastelands. Some of them underwent large-scale processing - they were cleared of debris, the soil was leveled, new grass was planted, small fences were put up around the perimeter. On others, only garbage was removed and the grass was mowed. Next, the scientists compared data on crime in the areas where the work took place, and where the wastelands remained the same as before. To do this, they studied police reports and conducted a survey of residents of the areas closest to the wastelands before and after improvement.

Even a minor improvement helped to reduce crime somewhat, by about 10%. In areas where the population lived below the poverty line, this figure was already 13%, and crimes with the use of firearms decreased by 30%. Residents of the districts also reported that they began to feel more secure.
