Gray Component Replacement. A technique for adding detail to an image by reducing the amounts of cyan, magenta, and yellow and replacing them with black.
Grey component replacement. A color separation setting used on color photographs where cyan, magenta and yellow inks are swapped out of an image (in a balance that would yield a grey value) and black ink is swapped in instead. The advantages are a reduction in overall ink usage, a more consistent press run, and some increase in image detail.
gray component replacement. Also called achromatic color replacement (ACR), integrated color removal (ICR), and polychromatic color removal (PCR). Removing the achromatic (also called contaminant or graying) component of cyan, magenta, and yellow when they all combine and replacing it with black. Gray component replacement is distinct from under color removal, which reduces process colors in only dark, neutral areas and adds black. GCR separation is done with specialized software on electronic scanners.

Geological Conservation Review. The GCR was initiated by the Nature Conservancy Council (1977) to assess and document the most important parts of Great Britain's rich geological heritage. Sites were selected based on the importance of the geology shown therein, with an attempt to select those with the most important, exceptional and representative geology. An attempt was also made to avoid repetition, to keep the overall number of sites to a minimum whilst still giving a complete picture. A series of books (including "British Upper Cretaceous Stratigraphy" ( R.N.Mortimore, C.J.Wood, R.W.Gallois) details these sites, and each site report is a justification of the particular scientific interest in a locality, of its importance in a British or international setting, and ultimately of its worthiness for conservation. The Downend Chalk Quarry at Portsdown is one such site.
Geological Conservation Review. A comprehensive assessment of all key sites of geological and geomorphological importance within the UK. All sites selected by the GCR are of national or international importance for geology or geomorphology.
Gas-Cooled Reactor
The actual cost of gas (Gas Cost Recovery) that the utility pays to producers and pipelines. By law, a utility cannot earn a profit on the sale of gas (see "base rate"). Cost of gas is a direct pass through to sales customers.
Gas cost recovery. Provision of regulatory rules permitting an LDC to recover from customers, on a dollar-for-dollar basis, the prudent amount it pays in purchase costs for the gas supplied to customers
Great Central Railway. The name adopted by the Manchester, Sheffield and Lincolnshire Railway (previously the Sheffield, Ashton and Manchester Railway) with the intention of becoming a national, rather than a regional, railway by opening the "London extension" to Marylebone via Nottingham and Leicester; it was grouped into the LNER in 1923. Not part of the LNWR but a joint owner, with the LNWR, of the Manchester South Junction and Altrincham line.
