This paper first provides a short review on variations of compound parabolic concentrator designs available to date.
Furthermore, a recent review on variations of cytochrome P450 in different ethnic populations suggests that ethnical differences in metabolic phenotype can be explained by differences in the distributions of SNPs [ 21].
Because of this variation, phylogenetic interpretations that use morphological features have been hindered by extensive homoplasy (see review of morphological variation [ 6]).
A review of biological variation has shown that cardiac troponin as a biomarker has low index of individuality, indicating that reference values are of little utility.
Up to five or six subspecies have been described, although a recent review of geographic variation recommended the recognition of only two subspecies: C. m. minuta, which is darker overall and occurs in Amazonia, and C. m. gracilis, which is generally paler and occurs in the chocó west of the Andes.
The Galaxy, July, 1868, volume 6, no. 1, pages 135 138, contains a review of The Variation of Animals and Plants under Domestication, which is a continuation of the inquiry opened by Mr. Darwin in his volume On the Origin of Species, in 1859.
This finding was consistent with a recent review of ethnic variation in dental caries in China that reported that ethnic minorities, such as the Zhuang, had higher levels of dental caries than the Han ethnic group [ 25].
In order to test if traits under abiotic v. biotic selection differ in variability, we used data amassed in a recent review of temporal variation in selection pressures [ 13], reclassifying the traits identified in this study as under abiotic or biotic selection.
He announced a review of "deeds of variation" – a way of changing a will after someone has died.
