Cohesion (chemistry)
Cohesion, cohesive attraction, or cohesive force is a physical property of an object. It happens because of intermolecular attraction between like-molecules.
Cohesion holds hydrogen bonds together to create surface tension on water. Since water is attracted to other molecules, adhesive forces pull the water toward other molecules.

Dave "Compact Dynamo" Mackintosh is the drummer and backup vocalist for the band DragonForce. The band changed their genre to 'Extreme Power Metal' after Dave started playing in the band. Dave does extreme metal drumming in DragonForce's music, such as blast beats.
Frédéric Leclercq
Frédéric Alexandre Leclercq (born June 23, 1978 in France) is the bassist for power metal band DragonForce and plays in his own band, Maladaptive, where he sings and plays guitar. He can play bass, guitar, keyboards, and can sing. He is a session musician for many other bands and is also a former member of the French power metal band Heavenly and played several shows with Carnival in Coal in 2006.

Valley of the Damned
Valley of the Damned is DragonForce's first album. It was released on 25 February, 2003.
Sonic Firestorm
Sonic Firestorm is the second studio album by English power metal band DragonForce released through on May 11, 2004.
All songs arranged by Sam Totman, Herman Li, Vadim Pruzhanov, ZP Theart, and Adrian Lambert.
Inhuman Rampage
Inhuman Rampage is the third studio album by English power metal band DragonForce. The album was released on 9 January 2006, and 20 June 2006 in North America. It is the first album with Frédéric Leclercq on bass. An inhuman rampage can also be just something that is not a human, or a human that is not really acting like a human, going on a rampage, which basically just means they are going crazy and messing a lot of stuff up.
All songs arranged by Herman Li, Sam Totman, ZP Theart and Vadim Pruzhanov.
Bavand dynasty
The Bavand dynasty (in Mazandarani: "Bävendiyun") was an Iranian dynasty that began in the early 7th century. Its rulers reigned for about 700 years over Tabaristan, on the southern shore of the Caspian Sea. The name of the dynasty comes from Bäv (also known as Farrukhzad), who ruled from 651 to 665. He was from the House of Ispahbudhan, a noble Parthian family which served the Sasanian Empire. The Bavandid rulers were originally Zoroastrian, but they later converted to Islam during the reign of Qarin I.
The Kayusiyya are named after Kawus, the son of the Sasanian ruler Kavadh I. It was founded by Bav (Farrukhzad), who repelled the Muslim Arabs from Tabaristan and ruled until he was murdered by the Karenid Valash in 665.
Dyson sphere
A Dyson sphere is an idea about a structure that surrounds a star, first thought up by physicist Freeman Dyson, and then used in some science fiction works.
The idea of the Dyson sphere was the result of a thought experiment. Dyson noted that civilizations constantly increased their need for energy. He reasoned that as human civilization went on, there would come a time when it demanded more energy than the Earth could provide.
He proposed a system of structures designed to intercept and collect all energy produced by the Sun. Dyson's proposal did not detail how such a system would be constructed. His 1960 paper "Search for artificial stellar sources of infra-red radiation", in the journal "Science", was the first to present the concept of the Dyson sphere.
There are at least three types of Dyson spheres:
Summerlee Heritage Park
Summerlee Heritage Park is an industrial museum in Coatbridge, North Lanarkshire, Scotland. It has won several awards. It was built on the old Summerlee ironworks. It also uses the main workshop of the old Hyrdocon Crane factory.
The museum closed in 2006 for a £10Million refurbishment. It re-opened in 2008.
The old main hall has been re-built. The museum tries to show Lanarkshire's contribution to engineering. There are interactive displays and a children's "Discovery Zone".
The museum also displays several railway steam locomotives, preserved carriages from a 1960s era Glasgow "Blue Train" and has a short working tramline.
Concert of Europe
The Concert of Europe was a group of countries in Europe who worked together and agreed on policies to maintain a steady balance of power which included alliances between the great powers in 1814 and 1914. The member countries were the United Kingdom, Austria, Russia, France (from 1815), Prussia (Germany from 1871) and Italy (from 1871).
It started as a quadruple alliance. After Napoleon, ruler of France, was no longer in power, France joined the Concert of Europe. Its importance diminished with the revolutions of 1848 and subsequent wars between the big powers. Otto von Bismarck re-established the Concert of Europe after the unifications of Germany and Italy. The Concert definitively collapsed with World War I.
The leaders of this concert include:
The Concert was also known as the Congress System, where leaders would meet and reach decisions by mutual agreement.
Important goals of the Concert:

Glow fuel
Glow fuel is a term used to tell about fuel used for model airplanes, helicopters, cars and boats. Glow fuel can be burned by very simple two-stroke engines or by four-stroke engines. Engines like this provide lots of power in a small size.
Sometimes, glow fuel is called nitro or just model fuel. Some model fuel has only a little bit of nitro, but some fuel has none at all. It is called "FAI fuel." "FAI" stands for Fédération Aéronautique Internationale. They say that models used in racing or other competition under their rules may not have any nitro in their mix.
Glow fuel is mostly made of methanol, nitromethane and oil.
Methanol is the main ingredient. It provides most of the fuel's ability to burn. In order to burn the glow fuel, a glow engine must have a glow plug. The glow plug burns very hot as the engine runs because of a catalytic reaction with the methanol. Since the engines turn very fast, a phenomenon known as thermal inertia helps to keep the plug glowing as the engine runs. A small amount of electricity is used to cause the glow plug to glow as the engine is started. Once the engine is running, the electricity is disconnected.
Nitromethane is added to the fuel for more power and to make the engine easier to tune. Nitromethane contains less energy than the same amount of methanol, but it requires less oxygen. This means that more of it can be put into an engine during each turn of the engine. This leads to more power.
Fuel for most model planes, boats and helicopters has 5% to 15% nitromethane. For use in race cars, the nitromethane can be from 30% to as much as 65%.
Nitromethane is hard to get in some countries since it is known as an explosive. In these countries, glow fuel sometimes has no nitromethane at all.
Since the engine doesn't have its own supply of oil, it's instead added to the fuel to help lubricate the moving parts and to keep them from burning up. The oil can be castor oil or synthetic oils. Some fuels include a mixture of the two. The oils included in glow fuel are not burned by the engine. Instead, the oil comes out of the exhaust. Not only does the oil lubricate the moving parts, but the oil which comes out the engine helps carry away extra heat.
