Glomerular Filtration Rate
Renal functions include maintaining an acid–base balance; regulating fluid balance; regulating sodium, potassium, and other electrolytes; clearance (medicine), clearing toxins; absorption of glucose, amino acids, and other small molecules; regulation of blood pressure; production of various hormones, such as erythropoietin; and activation of vitamin D. The kidney has many functions, which a well-functioning kidney realizes by filtering blood in a process known as glomerular filtration. A major measure of kidney function is the glomerular filtration rate (GFR). The glomerular filtration rate is the flow rate of filtered fluid through the kidney. The creatinine clearance rate (CCr or CrCl) is the volume of blood plasma that is cleared of creatinine per unit time and is a useful measure for approximating the GFR. Creatinine clearance exceeds GFR due to creatinine secretion, which can be blocked by cimetidine. Both GFR and CCr may be accurately calculated by comparative measurement ...

Grand Forks Railway
The Grand Forks Railway is a shortline railway company operating in the West Kootenay region of southeastern British Columbia. Former operators In Grand Forks, a former north–south section of the Kettle Valley Lines (KVL) (the operating company for the Kettle River Valley Railway (KRVR) and the Spokane and British Columbia Railway) both crossed and connected with the Canadian Pacific Railway (CP) line near the north end of today's 5 St. The KRVR became the CP's Kettle Valley Railway. Although the former KRVR track north of this crossing no longer exists, it continues southwest almost to the south end of today's Cooper Rd. The Pacific Abrasives & Supply yard is on the southeast corner of where the former KRVR crossed the former north–south Great Northern Railway (GN) spur that accessed north and northwest of Grand Forks. This abrasives company has been shipping processed slag from the former Granby smelter for use in sandblasting or coating roofing tiles. At this crossing, ...

Gas-cooled Fast Reactor
The gas-cooled fast reactor (GFR) system is a nuclear reactor design which is currently in development. Classed as a Generation IV reactor, it features a fast-neutron spectrum and closed fuel cycle for efficient conversion of fertile uranium and management of actinides. The reference reactor design is a helium- cooled system operating with an outlet temperature of using a direct Brayton closed-cycle gas turbine for high thermal efficiency. Several fuel forms are being considered for their potential to operate at very high temperatures and to ensure an excellent retention of fission products: composite ceramic fuel, advanced fuel particles, or ceramic clad elements of actinide compounds. Core configurations are being considered based on pin- or plate-based fuel assemblies or prismatic blocks, which allows for better coolant circulation than traditional fuel assemblies. The reactors are intended for use in nuclear power plants to produce electricity, while at the same time pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grup Feroviar Român
Grup Feroviar Român, or simply GFR, is the largest private railway company in Romania and one of the largest in South Eastern Europe. Founded in 2001, the company owns freight operations in Romania, Hungary, Bulgaria, Greece, Serbia, Ukraine, Moldova, Montenegro and Mozambique, and railcar production and maintenance operations in Romania, Hungary, Serbia and Ukraine. In 2010 GFR operated a park of over 13,500 railroad cars and 285 Diesel locomotive, diesel and electric locomotives. In 2013, GFR bought a 51% stake in CFR Marfă, which was the freight division of Căile Ferate Române. This purchase cost €202 million.

Government Flight Representative
A Government Flight Representative (GFR) is a US Military Officer or similarly qualified US Government Civilian with the responsibility for aircraft operations conducted by commercial contractors using Department of Defense (DoD) aircraft. Authority GFR authority derives from two Defense Federal Acquisition Regulation Supplement (DFARS) contract clauses known as the ''Ground and Flight Risk Clause'' and the ''Flight Risk Clause''. Any DoD contract involving the production, modification, maintenance, repair, or overhaul of aircraft must contain one of these two clauses which requires the US Government to assign a GFR to oversee the contractor's operations. These two clauses serve to both indemnify the contractor (reducing program expenses) and also to help protect the assets. Qualifications A GFR must be a current military aircraft crewmember or be a US Government Civilian with previous military aircraft experience. A week-long qualification course (operated by the Defense Contract ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grand Funk Railroad
Grand Funk Railroad (often shortened to Grand Funk) is an American rock band formed in Flint, Michigan, in 1969 by Mark Farner (vocals, guitar, keyboards, harmonica), Don Brewer (drums, vocals) and Mel Schacher (bass). The band achieved peak popularity and success during the 1970s with hit songs such as " We're an American Band", " I'm Your Captain (Closer to Home)", " Some Kind of Wonderful" (a cover of Soul Brothers Six), " Walk Like a Man", " The Loco-Motion" (a cover of Little Eva), " Bad Time" and " Inside Looking Out" (a cover of the Animals). Grand Funk released six platinum and seven gold-certified albums between their recording debut in 1969 and their first disbandment in 1976. Known for a crowd-pleasing arena rock style, the band toured extensively and played to packed arenas worldwide, and was well-regarded by audiences despite a relative lack of critical praise. The original trio reunited at various times later into the band's career; after Farner's final depar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fertility
Fertility in colloquial terms refers the ability to have offspring. In demographic contexts, fertility refers to the actual production of offspring, rather than the physical capability to reproduce, which is termed fecundity. The fertility rate is the average number of children born during an individual's lifetime. In medicine, fertility refers to the ability to have children, and infertility refers to difficulty in reproducing naturally. In general, infertility or subfertility in humans is defined as not being able to conceive a child after one year (or longer) of unprotected sex. The antithesis of ''fertility'' is infertility, while the antithesis of ''fecundity'' is sterility. Demography In demographic contexts, fertility refers to the actual production of offspring, rather than the physical capability to produce which is termed fecundity. While fertility can be measured, fecundity cannot be. Demographers measure the fertility rate in a variety of ways, which can be broa ...
