Tracer Ammunition
Tracer ammunition (AMO) (Tracers) are bullets or cannon-caliber projectiles that are built with a small pyrotechnic charge in their base. When fired, the pyrotechnic composition is ignited by the burning powder and burns very brightly, making the trajectory of a projectile, projectile trajectory visible to the naked eye during daylight, and very bright during nighttime firing. This allows the shooter to visually trace the flight path of the projectile and thus make necessary ballistic corrections, without having to confirm projectile impacts and without even using the sight (device), sights of the weapon. Tracer fire can also be used as a marking tool to signal other shooters to concentrate their fire on a particular target during battle. When used, tracers are usually loaded as every fifth Cartridge (firearms), round in Belt (firearms), machine gun belts, referred to as four-to-one tracer. Platoon and squad leaders will load some tracer rounds in their Magazine (firearms), mag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grumman E-1 Tracer
The Grumman E-1 Tracer was the first purpose-built airborne early warning aircraft used by the United States Navy. It was a derivative of the Grumman C-1 Trader and entered service in 1958. It was replaced by the more modern Grumman E-2 Hawkeye by the 1970s. Design and development The E-1 was designated WF under the 1922 United States Navy aircraft designation system; the designation earned it the nickname "Willy Fudd". The Tracer was derived from the C-1 Trader, itself a derivative of the S-2 Tracker carrier-based antisubmarine aircraft, known as S2F under the old system, nicknamed "Stoof", leading to the WF/E-1, with its distinctive radome, being known as "Stoof with a Roof."O'Rourke, G.G., CAPT USN. "Of Hosenoses, Stoofs, and Lefthanded Spads". ''United States Naval Institute Proceedings'', July 1968. The E-1 featured folding wings of a very particular design for compact storage aboard aircraft carriers; unlike the S-2 and C-1 in which the wings folded upwards, the radome ...

Flow Tracer
A flow tracer is any fluid property used to track flow, magnitude, direction, and circulation patterns. Tracers can be chemical properties, such as radioactive material, or chemical compounds, physical properties, such as density, temperature, salinity, or dyes, and can be natural or artificially induced. Flow tracers are used in many fields, such as physics, hydrology, limnology, oceanography, environmental studies and atmospheric studies. Conservative tracers remain constant following fluid parcels, whereas reactive tracers (such as compounds undergoing a mutual chemical reaction) grow or decay with time. ''Active tracers'' dynamically alter the flow of the fluid by changing fluid properties which appear in the equation of motion such as density or viscosity, while ''passive tracers'' have no influence on flow. Uses in oceanography Ocean tracers are used to deduce small scale flow patterns, large-scale ocean circulation, water mass formation and changes, "dating" of water ...

Mercury Tracer
The Mercury Tracer is an automobile manurfactured and marketed by Ford's Mercury division for model years 1987-1999, over three generations in three- and five-door hatchback, four-door sedan, and five-door station wagon configurations. The first generation was marketed as a subcompact; the two succeeding generations were sold in the compact segment. All three generations derived from the Mazda 323/Protegé. After 1999, Mercury ended sales of the Tracer; while the Ford Escort was later replaced by the Ford Focus, Mercury exited the compact segment. A planned Tracer fourth generation was projected for 2012, cancelled by the closure of the Mercury brand at the end of 2010. First generation (1987–1989) For 1987, Mercury introduced the Tracer as its subcompact model range to replace the Lynx. The first Mercury-brand vehicle assembled outside of North America, the Tracer was a counterpart of the Ford Laser (itself a variant of the Mazda 323) [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Night Castle
''Night Castle'' is the fifth rock opera by the Trans-Siberian Orchestra. It was released on October 28, 2009 as a double CD with a 60-page booklet illustrated by Greg Hildebrandt, and debuted at No. 5 on the Billboard charts and No. 1 on the rock music charts. It was certified gold in eight weeks and is currently a platinum album.

While they build a sandcastle together by the light of a bonfire, he tells her a tale that takes her all around the world and throughout history. The characters of this story include an American Vietnam War soldier named William Cozier, the Renaissance era philosopher Erasmus who is keeper of the eponymous castle of lost knowledge, and a Communist general based on the dissident Tran Do. In 2011, Atlantic released the album on vinyl in an eight side (four disc) set in a special slip box designed to avoid the cra ...

Was I The Wave? . ''Was I the Wave?'' is the second studio album by Miracle Fortress, released on April 26, 2011. The album departs from the indie rock of '' Five Roses'', and is instead more of an electronic offering. As with ''Five Roses'', all songs were composed, arranged, performed, produced, and engineered by Graham Van Pelt. For live performances, Van Pelt is accompanied on-stage by fellow Think About Life bandmate Greg Napier. Reception On its release, the album received a favourable review in the ''Montreal Gazette'' from Bernard Perusse, garnering a rating of 4 out of 5 stars. The album was named as a longlisted nominee for the 2011 Polaris Music Prize The 2011 edition of the Canadian Polaris Music Prize was presented on September 19, 2011 [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radioactive Tracer
A radioactive tracer, radiotracer, or radioactive label is a chemical compound in which one or more atoms have been replaced by a radionuclide so by virtue of its radioactive decay it can be used to explore the mechanism of chemical reactions by tracing the path that the radioisotope follows from reactants to products. Radiolabeling or radiotracing is thus the radioactive form of isotopic labeling. In biological contexts, use of radioisotope tracers are sometimes called radioisotope feeding experiments. Radioisotopes of hydrogen, carbon, phosphorus, sulfur, and iodine have been used extensively to trace the path of biochemical reactions. A radioactive tracer can also be used to track the distribution of a substance within a natural system such as a cell or tissue, or as a flow tracer to track fluid flow. Radioactive tracers are also used to determine the location of fractures created by hydraulic fracturing in natural gas production.Reis, John C. (1976). ''Environmental Con ...

Isotopic Tracer
Isotopic labeling (or isotopic labelling) is a technique used to track the passage of an isotope (an atom with a detectable variation in neutron count) through a reaction, metabolic pathway, or cell. The reactant is 'labeled' by replacing specific atoms by their isotope. The reactant is then allowed to undergo the reaction. The position of the isotopes in the products is measured to determine the sequence the isotopic atom followed in the reaction or the cell's metabolic pathway. The nuclides used in isotopic labeling may be stable nuclides or radionuclides. In the latter case, the labeling is called radiolabeling. In isotopic labeling, there are multiple ways to detect the presence of labeling isotopes; through their mass, vibrational mode, or radioactive decay. Mass spectrometry detects the difference in an isotope's mass, while infrared spectroscopy detects the difference in the isotope's vibrational modes. Nuclear magnetic resonance detects atoms with different gyromagne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tandem Reconnection And Cusp Electrodynamics Reconnaissance Satellites
Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (TRACERS) is a planned orbiter mission tasked to study the origins of the solar wind and how it affects Earth. The Principal Investigator is Craig Kletzing at the University of Iowa in Iowa City, Iowa. Not including rideshare costs, TRACERS is funded US$115 million. Overview TRACERS is a pair of identical spacecraft that will be launched as a secondary mission to another orbiter named Polarimeter to Unify the Corona and Heliosphere (PUNCH) and will operate in synergy; PUNCH will study the solar wind, a stream of charged particles emanating from the Sun, while TRACERS will study Earth's response.
