M. avium and M. intracellulare were universally identified and distinguished by the ability of M. intracellulare to cause virulence in chicken [41], thus illustrating their different immunological attributes and distinct niche preferences.
However, in the current human genome primary reference assembly, both NANOG and NANOGP8 contain this deletion, indicating that it is not a universally reliable distinguishing feature.
Although there is no universally agreed upon definition of mass murder, it is distinguished from serial murder by its several victims being killed at the same time and place, whereas serial murder involves the unlawful homicide of at least two victims carried out in a series over a period of time.
It is universally agreed, however, that the East End is to be distinguished from East London, which covers a much wider area.
Pkd1endo− and Pkd2endo− embryos universally developed polyhydramnios (Figure 6, Figure S2) and could be easily distinguished from wild type littermates.
A second caveat is that many HT genes that are currently segregating could be beneficial, but only at a very local scale, so they remain at low frequency in the species as a whole (Hao and Golding 2006; Doolittle and Zhaxybayeva 2009)—the approach we used cannot distinguish between universally deleterious mutations and mutations that are locally beneficial, but deleterious on a larger scale.
First, moral norms have to be distinguished from mere social conventions in that they are somehow regarded to be universally valid, independent from the commands of social authority and a particular culture.
But it's hard to square the existence of such a universally applicable requirement with some other claims Kant makes about how hypothetical imperatives are to be distinguished from categorical ones, and how hypothetical imperatives could be derived from an analysis of the concept of willing an end (Schroeder 2005b; for a related discussion of these issues, see Schwartz 2008).
Ernest Watson, known universally as Doc, has seen the crowds ebb and flow as the tenor saxophonist for the Olympia Brass Band, the oldest and most distinguished of the city's indigenous jazz ensembles.
