Murder
Murder is the unlawful killing of another human without justification (jurisprudence), justification or valid excuse (legal), excuse, especially the unlawful killing of another human with malice aforethought. ("The killing of another person without justification or excuse, especially the crime of killing a person with malice aforethought or with recklessness manifesting extreme indifference to the value of human life.") This state of mind may, depending upon the jurisdiction (area), jurisdiction, distinguish murder from other forms of unlawful homicide, such as manslaughter. Manslaughter is killing committed in the absence of Malice (law), ''malice'',This is "malice" in a technical legal sense, not the more usual English sense denoting an emotional state. See malice (law). brought about by reasonable Provocation (legal), provocation, or diminished capacity.

Welding
Welding is a fabrication (metal), fabrication process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool, causing Fusion welding, fusion. Welding is distinct from lower temperature techniques such as brazing and soldering, which do not melting, melt the base metal (parent metal). In addition to melting the base metal, a filler material is typically added to the joint to form a pool of molten material (the weld pool) that cools to form a joint that, based on weld configuration (butt, full penetration, fillet, etc.), can be stronger than the base material. Pressure may also be used in conjunction with heat or by itself to produce a weld. Welding also requires a form of shield to protect the filler metals or melted metals from being contaminated or Oxidation, oxidized. Many different energy sources can be used for welding, including a gas flame (chemical), an electric arc (electrical), a laser, an electron ...

Copenhagen Suborbitals
Copenhagen Suborbitals is an amateur, crowd-funded, and open-source human space program. Since its beginning in 2008, Copenhagen Suborbitals has flown five home-built rockets and two mock-up space capsules. Their stated goal is to have one of the members fly into space (above 100 km), on a sub-orbital spaceflight, in a space capsule on the Spica rocket. The organisation was founded by Kristian von Bengtson and Peter Madsen. The organization successfully launched its Nexø II rocket in the summer of 2018. As an amateur organization, the 55 members use their spare time on the project, while at the same time having regular day-jobs. At the annual general assembly, they elect a chairman and board members. , the chairman is Carsten Olsen. History Copenhagen Suborbitals was founded in 2008 by Kristian von Bengtson and Peter Madsen as a non-profit, crowd-funded project where important aspects of the operation were described in detail on blogs and lectures.

United States Dollar
The United States dollar ( symbol: $; code: USD; also abbreviated US$ or U.S. Dollar, to distinguish it from other dollar-denominated currencies; referred to as the dollar, U.S. dollar, American dollar, or colloquially buck) is the official currency of the United States and several other countries. The Coinage Act of 1792 introduced the U.S. dollar at par with the Spanish silver dollar, divided it into 100 cents, and authorized the minting of coins denominated in dollars and cents. U.S. banknotes are issued in the form of Federal Reserve Notes, popularly called greenbacks due to their predominantly green color. The monetary policy of the United States is conducted by the Federal Reserve System, which acts as the nation's central bank. The U.S. dollar was originally defined under a bimetallic standard of (0.7735 troy ounces) fine silver or, from 1837, fine gold, or $20.67 per troy ounce. The Gold Standard Act of 1900 linked the dollar solely to gold. From 1934, it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Midget Submarine
A midget submarine (also called a mini submarine) is any submarine under 150 tons, typically operated by a crew of one or two but sometimes up to six or nine, with little or no on-board living accommodation. They normally work with mother ships, from which they are launched and recovered and which provide living accommodation for the crew and support staff. Both military and civilian midget submarines have been built. Military types work with surface ships and other submarines as mother ships. Civilian and non-combatant military types are generally called submersibles and normally work with surface ships. Most early submarines would now be considered midget submarines, such as the United States Navy's and the British Royal Navy's (both named for the same John Philip Holland, designer). Military submarines Uses Midget submarines are best known for harbor penetration, although only two World War II boats, the British X-class submarine, X-craft and the unsuccessful Welman subm ...

UC2 Kraka
''Kraka'', or UC2 ''Kraka'' was an amateur-built midget submarine completed in 2005, the first diesel–electric amateur sub in Denmark. It was built by Peter Madsen, Claus Nørregaard and several other people. The overall length was , and it displaced 6 tonnes. The propulsion was diesel–electric with a 16 hp diesel engine and an 8 hp electric motor. ''Kraka'' can be seen at Denmark's Technical Museum in Elsinore (aka Helsingør). '' Kraka'' is named after a woman in Norse mythology known for her intelligence. Construction The sub was built at Peter Madsen's workshop in Farum, Denmark. Construction took years and over 3600 hours to build. It was built with two engines, a diesel and an electric, making the sub a diesel-electric. With a diesel drive, this theoretically allows the sub to have a range, and up to submerged. It can run at a speed of on the surface, and submerged, using the snorkel and with extra fuel aboard. The boat is long, wide, with d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UC1 Freya
''Freya'' or UC1 ''Freya'' (in Danish: ''Freja'') was the first private Danish submarine, and thus first amateur electric sub in Denmark. It was built by Peter Madsen and Claus Nørregaard in 2001–2002, as a demonstrator to try submarine technology. Having made over 500 dives, it was decommissioned, as it was not designed for a long service life. It was decommissioned in 2006 after ''UC2 Kraka'' had been worked up. The submarine was then docked and allowed to decay. Final decontamination was done, and it was towed out to sea by '' UC3 Nautilus'', in August 2008, and sunk as an artificial reef near Copenhagen. Peter Madsen, email notice"[PSUBS-MAILIST] UC3 Nautilus at sea with UC1 Freya..." 10 Aug 2008 ''Freya'' is named after the Norse goddess of fertility and love. Construction The sub was built at Peter Madsen's workshop in Farum, Denmark. ''Freya'' was completed in 2002. It was built with only an electric drive, a 3.1-kW Sauer-Danfoss 24V DC electric motor. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kristian Peter Launch2011
Kristian is a name in several languages, and is a form of Christian. Meaning in different languages The name is used in several languages, among them Albanian, Slovak, Danish, Finnish, Norwegian, Swedish, Bosnian, Macedonian, Bulgarian and Croatian. In some languages people with the name are sometimes named after the cross, not after Christ. The word cross in Bulgarian, Macedonian, Serbian is ''kr'st'' and in Russian is ''krest'', in some cases pronounced ''krist''. In contrast Christ in these Slavic languages is called ''Hristos'', which confuses to which of both nouns the name sounds more similar. The name may have a third meaning in Bulgarian and Macedonian, in which the word ''kr'sten'' means baptized and has the same as the word for cross. Though sounding similar, the words cross and Christian have different roots, ''Christian'' derives from the Koine Greek word ''Christós'', possibly ultimately derived from the Egyptian ''kheru'', "word" or "voice", used to replace ...
