asymmetric icebreaker

13.08.2013

For many years, shipbuilders have been working on improving the design of icebreakers. The profit of the carrier company directly depends on the quality of the icebreaker’s work: if the icebreaker manages to break through the ice, then ships with various cargoes can pass unhindered along the northern routes even in the winter months. Of course, countries facing the sea, including Russia (it supplies some parts for the new icebreaker), are striving to find convenient routes for the quick delivery of goods to Europe by sea.

It is assumed that the Baltika icebreaker, which is being built by the Finnish shipbuilding company Arctech Helsinki Shipyard (Finland), will solve some of the problems.

The new ship will have a bow on one side, which will allow you to move forward at an angle. The vessel will be equipped with three engines (9 MW total power / 7,5 MW propulsion power). They will be installed at the very bottom and will be able to rotate 360 degrees. In addition, the ship will be equipped with a unique system of pumps to move liquid fuel and water from the holds to tanks inside the hull to change its center of gravity. Thus, the ship will be able to go straight, at an angle, or even in the opposite direction. In their message, representatives of Arctech said that the new icebreaker will not only be able to cut through the ice in the Gulf of Finland, but also help in oil spill areas and in rescue operations.

The dimensions of the ship will be 76 meters long and 20 meters wide. Usually a vessel of this size can clear a path only slightly wider than itself. However, the Baltika icebreaker will be able to clear a 50 m wide path in 60 cm thick ice. This is enough for a tanker to follow.

According to shipbuilders, the Baltika icebreaker should be ready next spring.

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 ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. 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, ... >>

Background music interferes with the creative process 26.02.2019

Researchers from the University of Central Lancashire, the University of Lancaster (UK) and the University of Gävle (Sweden) investigated how background music affects the quality of performance of tasks related to "linguistic creativity". They found that background music "significantly impairs" people's creative thinking levels.

An experiment helped scientists come to this conclusion. Its participants were shown three words: "dress", "dial", "flower" (dress, dial, flower) - and they had to find one word (in this case, "sun", sun), which can be combined with the three above to form a new word or phrase: "sundress", "sundial" and "sunflower" (sundress, sundial and sunflower).

During this task, different music played in the background. In the first case - a song with lyrics in a foreign language, in the second - instrumental music without words, in the third - a song in the native language.

Dr Neil McLatchie of Lancaster University said: "We have found compelling evidence that human performance is impaired when music is played in the background." It does not matter if there is text in it and in what language it is. The researchers suggest that this may be due to the fact that music impairs verbal working memory.

It is noteworthy that the participants in the experiment performed equally well when there was no extraneous noise in the background or when they were surrounded only by the noise of the library. This is because, psychologists say, library noise is a "steady state" of the environment that is not so destructive.
