With considerable skill, Grey had invented an American persona, Tippi Gray, and it was under this name that he joined three bobsleighing friends and won gold medals in both the 1928 and the 1932 winter Olympic games".
While the loss of hair pigmentation is fully dominant, the speed of greying, amount of speckling, incidence of melanomas and presence of vitiligo-like depigmentation show considerable variation among Grey horses.
Drawing on surveys of models of ART care and analyses of the policy process conducted in the three provinces between 2005 and 2007, as well as a considerable body of grey and indexed literature on ART scale up in South Africa, it draws links between implementation processes and variations in provincial ART coverage (low, medium and high) achieved in the three provinces.
Although the lesions in dog 2 affected a smaller area of the spinal cord, a considerable area of both grey and white matter was affected also in this dog.
Some may have a uniform slate-grey color, but others demonstrate a considerable variation of dark blues, greys and blacks, all tightly mottled.

In addition, a considerable part of the Dutch grey literature is based on documents issued by supranational institutions (e.g. the WHO checklist, ECDC or CDC guidelines).
Though we miss a considerable proportion of true edges (shaded in grey in panel b), the very high specificity is particularly encouraging, as it suggests that positive findings are very reliable.
This could be an interesting issue since the brain undergoes considerable changes with advancing age, such as shrinkage of grey matter volume and white matter loss [15] as well as neural and functional reorganizations [16].
