Georgia Tech Foundation
The Georgia Tech Foundation provides financial assistance to the Georgia Institute of Technology. It was founded in 1932 and chartered under the tax laws of the United States as a non-profit 501(c)(3) corporation. In 2013, the Foundation provided $130.8 million in support of the Institute, including $20.7 million in scholarships, fellowships and loan funds to 3,563 students. As of June 30, 2013, the Foundation had $1.729 billion in assets. In 2013, the Foundation provided financial support for 200 students to participate in the G.

General Transcription Factor
General transcription factors (GTFs), also known as basal transcriptional factors, are a class of protein transcription factors that bind to specific sites (Promoter (genetics), promoter) on DNA to activate Transcription (genetics), transcription of genetic information from DNA to messenger RNA. GTFs, RNA polymerase, and the Mediator (coactivator), mediator (a multi-protein complex) constitute the basic transcriptional apparatus that first bind to the promoter, then start transcription. GTFs are also intimately involved in the process of gene regulation, and most are required for life. A transcription factor is a protein that binds to specific DNA sequences (Enhancer (genetics), enhancer or promoter), either alone or with other proteins in a complex, to control the rate of transcription of genetic information from DNA to messenger RNA by promoting (serving as an Activator (genetics), activator) or blocking (serving as a repressor) the recruitment of RNA polymerase. As a class of pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pratt & Whitney GTF
The Pratt & Whitney PW1000G, also called the Geared Turbofan (GTF), is a high-bypass geared turbofan engine family produced by Pratt & Whitney. After many demonstrators, the program was launched with the Mitsubishi MRJ's PW1200G in March 2008, and it was first flight tested in July 2008. The first variant to be certified was the PW1500G for the Airbus A220 in February 2013. The program cost is estimated at $10 billion. The gearbox between the fan and the low-pressure spool allows each to spin at its optimal speed, allowing a higher bypass ratio for a better propulsive efficiency. Pratt & Whitney claims the engine is 16% more fuel efficient than the previous generation, and up to 75% quieter. The first variant to enter service was the PW1100G for the A320neo in January 2016. The engine had teething problems after its introduction, extending to grounded aircraft and inflight failures, solved afterwards. The variants can generate 15,000 to 33,000 lbf (67 to 147 kN) of thrust. Bes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geared Turbofan
The geared turbofan is a type of turbofan aircraft engine, with a gearbox between the fan and the low pressure shaft to spin each at optimum angular velocities. Technology In a conventional turbofan, a single shaft (the "low-pressure" or LP shaft) connects the fan, the low-pressure compressor and the low-pressure turbine (a second concentric shaft connects the high-pressure compressor and high-pressure turbine). In this configuration, the maximum tip speed for the larger radius fan limits the rotational speed for the LP shaft and thus the LP compressor and turbine. At high bypass ratios (and thus high radius ratios) the tip speeds of the LP turbine and LP compressor must be relatively low, which means extra compressor and turbine stages are required to keep the average stage loadings and, therefore, overall component efficiencies to an acceptable level. In a geared turbofan, a planetary reduction gearbox between the fan and the LP shaft allows the latter to run at a higher ro ...

Generalized Timing Formula
Generalized Timing Formula is a standard by VESA which defines exact parameters of the component video signal for analogue VGA display interface. The video parameters defined by the standard include horizontal blanking (retrace) and vertical blanking intervals, horizontal frequency and vertical frequency (collectively, pixel clock rate or video signal bandwidth), and horizontal/vertical sync polarity. Unlike predefined discrete modes (VESA DMT), any mode in a range can be produced using a formula by GTF. A GTF-compliant display is expected to calculate the blanking intervals from the signal frequencies, producing a properly centered image. At the same time, a compliant graphics card is expected to use the calculation to produce a signal that will work on the display — either a GTF default formula for then-ordinary CRT displays or via a custom formula provided via EDID signaling. These parameters are used by the XFree86 Modeline, for example. This video timing standard is av ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Glycosyltransferase
Glycosyltransferases (GTFs, Gtfs) are enzymes ( EC 2.4) that establish natural glycosidic linkages. They catalyze the transfer of saccharide moieties from an activated nucleotide sugar (also known as the "glycosyl donor") to a nucleophilic glycosyl acceptor molecule, the nucleophile of which can be oxygen- carbon-, nitrogen-, or sulfur-based. The result of glycosyl transfer can be a carbohydrate, glycoside, oligosaccharide, or a polysaccharide. Some glycosyltransferases catalyse transfer to inorganic phosphate or water. Glycosyl transfer can also occur to protein residues, usually to tyrosine, serine, or threonine to give O-linked glycoproteins, or to asparagine to give N-linked glycoproteins. Mannosyl groups may be transferred to tryptophan to generate C-mannosyl tryptophan, which is relatively abundant in eukaryotes. Transferases may also use lipids as an acceptor, forming glycolipids, and even use lipid-linked sugar phosphate donors, such as dolichol phosphates in eukaryotic o ...

Glucose Tolerance Factor
Chromium deficiency is described as the consequence of an insufficient dietary intake of the mineral chromium. Chromium was first proposed as an essential element for normal glucose metabolism in 1959, and was widely accepted as being such by the 1990s. Cases of deficiency were described in people who received all of their nutrition intravenously for long periods of time. The essentiality of chromium has been challenged. Whereas the authorities in the European Union do not recognize chromium as an essential nutrient, those in the United States do, and identify an adequate intake for adults as between 25 and 45 μg/day, depending on age and sex. Dietary supplements containing chromium are widely available in the United States, with claims for benefits for fasting plasma glucose, hemoglobin A1C and weight loss. Reviews report the changes as modest, and without scientific consensus that the changes have a clinically relevant impact. Signs and symptoms The claimed symptoms of chromiu ...

Gene Transfer Format
The Gene transfer format (GTF) is a file format used to hold information about gene structure. It is a tab-delimited text format based on the general feature format (GFF), but contains some additional conventions specific to gene information. A significant feature of the GTF that can be validated: given a sequence and a GTF file, one can check that the format is correct. This significantly reduces problems with the interchange of data between groups. GTF is identical to GFF, version 2. from Ensembl

Graduate Theological Foundation
The Graduate Theological Foundation (GTF) is an American nonprofit interreligious institution of higher learning, originally founded in Indiana but now centered in Oklahoma City, Oklahoma. Unlike traditional residential theological schools, the foundation focuses on continuing educational opportunities for practicing ministry professionals, administrators, and academics who want to pursue advanced degrees while retaining their current position. Students and faculty reside around the world, and scholarly work takes place through onsite, online and distance learning engagement. Students are eligible to earn bachelors, masters, and doctoral degrees in a variety of theological disciplines. Faculty members come from a broad spectrum of faith backgrounds, and many also serve on the faculty of established colleges and universities, including the University of Oxford, with which the foundation has a continuing education affiliation through the Oxford Theology Summer School.
