Ozone
Ozone () (or trioxygen) is an Inorganic compound, inorganic molecule with the chemical formula . It is a pale blue gas with a distinctively pungent smell. It is an allotrope of oxygen that is much less stable than the diatomic allotrope , breaking down in the lower atmosphere to (dioxygen). Ozone is formed from dioxygen by the action of ultraviolet (UV) light and electrical discharges within the Earth's atmosphere. It is present in very low concentrations throughout the atmosphere, with its highest concentration high in the ozone layer of the stratosphere, which absorbs most of the Sun's ultraviolet (UV) radiation. Ozone's odor is reminiscent of chlorine, and detectable by many people at concentrations of as little as in air. Ozone's O3 chemical structure, structure was determined in 1865. The molecule was later proven to have a bent structure and to be weakly diamagnetism, diamagnetic. At standard temperature and pressure, ozone is a pale blue gas that condenses at cryogenic ...

Captain (United States O-3)
Captain in the U.S. Army (), U.S. Marine Corps (USMC), U.S. Air Force (USAF), and U.S. Space Force (USSF) (abbreviated "CPT" in the and "Capt" in the USMC, USAF, and USSF) is a company-grade officer rank, with the pay grade of O-3. It ranks above first lieutenant and below major. It is equivalent to the rank of lieutenant in the Navy/Coast Guard officer rank system and is different from the higher Navy/Coast Guard rank of captain. The insignia for the rank consists of two silver bars, with slight stylized differences between the Army/Air Force version and the Marine Corps version. History The U.S. military inherited the rank of captain from its British Army forebears. In the British Army, the captain was designated as the appropriate rank for the commanding officer of infantry companies, artillery batteries, and cavalry troops, which were considered as equivalent-level units. Captains also served as staff officers in regimental and brigade headquarters and as aides ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oskarshamn Nuclear Power Plant
The Oskarshamn Nuclear Power Plant is one of three active nuclear power stations in Sweden. The plant is about north of Oskarshamn, directly at the Kalmarsund at the Baltic Sea coast and with one active reactor, producing about 10% of the electricity needs of Sweden. All reactors were built using BWR technology. Unit 1 had an installed output of 494 MW and Unit 2 664 MW; these are now decommissioned. Unit 3, the newest reactor block at the facility, has an installed output of 1,450 MW. Clab, the temporary storage facility for spent nuclear fuel from all Swedish reactors, is also located at the site. Operator The responsible utility is OKG, short for the ''Oskarshamnsverkets Kraftgrupp AB'', which was acquired by Sydkraft in 1993, (later: '' E.ON Sverige''). Uniper owns 54.5% and the other partner Fortum 45.5% of OKG. History On 23 September 2003, Unit 3 of the reactor was shut down due to mechanical problems, and together with a failure that occurred in a ...

LNER Class O3
The Great Northern Railway (GNR) Class O1 was a class of two-cylinder 2-8-0 steam locomotive designed by Nigel Gresley for heavy freight work and built by the GNR between 1913 and 1919. History Gresley designed the O1 2-8-0 for the heavy coal trains on the mainline from Grantham to London, ordering five examples 1913, which were completed at Doncaster in 1914. A further fifteen were ordered in January 1916, but due to the First World War delays were incurred and construction was transferred to the North British Locomotive Company, who delivered the first ten in April 1918, followed by a further five in October and November 1919. The class was re-designated O3 by the London and North Eastern Railway in 1944 to release the O1 classification for use with the LNER Thompson Class O1 introduced during the Second World War. British Railways Seventeen examples survived into British Railways ownership in 1948, but all had been withdrawn by 1952 and scrapped after World War 2 ...

Otoyol 3
Otoyol 3 (), also known as the European Motorway () and abbreviated as the O-3 is a long otoyol in East Thrace, Turkey. The O-3 runs from Edirne to Istanbul and is the only motorway in Turkey located entirely in Europe. The motorway begins west of Edirne at "Edirne Batı K1" junction with the State road D.100 (Turkey), D.100 where it then continues as a beltway passing just north of Edirne. From there, the motorway passes through mostly rural farmland until it enters the Istanbul metropolis near Silivri. The eastern end of O-3 ends at the Istanbul Bağcılar "Mahmutbey Batı K20" Junction. O-3 "Avrupa otoyolu" "Mahmutbey Batı K19" junction connects to Otoyol 7, O-7, European route E80, E80, Istanbul Airport and Yavuz Sultan Selim Bridge in the north direction, to Ataturk Airport with the 2nd Beltway in the south direction. The last junction of the European motorway "Mahmutbey Doğu K20" connects to O-2 motorway (2nd Beltway) and Fatih Sultan Mehmet Bridge in the east direction, ...

Oldershaw O-3
The Oldershaw O-3 is an American high-wing, single seat, V-tailed glider that was designed by Vernon Oldershaw. Two examples were constructed as gliders and then both were later converted to motor gliders.Said, Bob: ''1983 Sailplane Directory, Soaring Magazine'', page 51. Soaring Society of America November 1983. USPS 499-920 Design and development The O-3 was designed by Oldershaw as an improved version of the O-2 to complete in the FAI Open Class. As such it had longer and higher aspect ratio wings of span. The O-3 first flew in June 1967. It is constructed of wood, with the nose made from fibreglass. Its wing employs a Wortmann 61-184 airfoil at the wing root, with a Wortmann 60-126 at the wing tip. The wing is equipped with trailing edge dive brakes. The landing gear is a retractable monowheel. Both aircraft were constructed as pure gliders and then later motorized with the addition of a twin-cylinder, in-line Yamaha snowmobile engine. The engine is mounted behind t ...

Lieutenant (navy)
LieutenantThe pronunciation of ''lieutenant'' is generally split between , , generally in the United Kingdom, Ireland, and Commonwealth countries, and , , generally associated with the United States. See lieutenant. (abbreviated Lt, LT (U.S.), LT(USN), Lieut and LEUT, depending on nation) is a commissioned officer rank in many English-speaking nations' navies and coast guards. It is typically the most senior of junior officer ranks. In most navies, the rank's insignia may consist of two medium gold braid stripes, the uppermost stripe featuring an executive curl in many Commonwealth of Nations; or three stripes of equal or unequal width. The now immediately senior rank of lieutenant commander was formerly a senior naval lieutenant rank. Many navies also use a subordinate rank of sub-lieutenant. The appointment of "first lieutenant" in many navies is held by a senior lieutenant. This naval lieutenant ranks higher than an army lieutenants; within NATO countries the na ...

Uniformed Services Pay Grades Of The United States
Pay grades are used by the eight structurally organized uniformed services of the United States (United States Army, Army, United States Marine Corps, Marine Corps, United States Navy, Navy, United States Air Force, Air Force, United States Space Force, Space Force, United States Coast Guard, Coast Guard, United States Public Health Service Commissioned Corps, Public Health Service Commissioned Corps, and NOAA Commissioned Officer Corps), as well as the United States Maritime Service, Maritime Service, to determine wages and benefits based on the corresponding military rank of a member of the services. While different ranks may be used among the eight uniformed services, pay grades are uniform and equivalent between the services and can be used to quickly determine seniority among a group of members from different services. They are also essential when determining a member's entitlements such as United States military pay, basic pay and allowances. Structure Pay grades are divid ...

O(3)
In mathematics, the orthogonal group in dimension , denoted , is the group of distance-preserving transformations of a Euclidean space of dimension that preserve a fixed point, where the group operation is given by composing transformations. The orthogonal group is sometimes called the general orthogonal group, by analogy with the general linear group. Equivalently, it is the group of orthogonal matrices, where the group operation is given by matrix multiplication (an orthogonal matrix is a real matrix whose inverse equals its transpose). The orthogonal group is an algebraic group and a Lie group. It is compact. The orthogonal group in dimension has two connected components. The one that contains the identity element is a normal subgroup, called the special orthogonal group, and denoted . It consists of all orthogonal matrices of determinant 1. This group is also called the rotation group, generalizing the fact that in dimensions 2 and 3, its elements are the usual rotatio ...
