BACKGROUND Fully asexually reproducing taxa lack outcrossing. Hence, the classic Biological Species Concept cannot be applied. METHODOLOGY/PRINCIPAL FINDINGS We used DNA sequences from the mitochondrial COI gene and the nuclear ITS2 region to check species boundaries according to the evolutionary genetic (EG) species concept in five morphospecies in the putative ancient asexual ostracod gener...

Parker (1) has shown that the results of infectivity measurements with vaccinia virus may be interpreted as a Poisson distribution of single infective particles among aliquots of the virus obtained by dilution. Thus, if it may be assumed that there exists a quanti ty of virus invariably necessary and invariably sufficient to produce a lesion in the skin of the rabbit, the behavior on dilution r...

This paper discussed an empirical research on success factors in innovation projects and analyzed the effect of environmental idiosyncrasies on their relative importance. Based on a cross-national survey, the study extracted five common success factors in China and Western developed countries. They are, namely, marketing skills, project strategy and process, management methodology and organizat...

DRB is a classic inhibitor of transcription elongation by RNA polymerase II (pol II). Since DRB generally affects class II genes, factors involved in this process must play fundamental roles in pol II elongation. Recently, two elongation factors essential for DRB action were identified, namely DSIF and P-TEFb. Here we describe the identification and purification from HeLa nuclear extract of a t...

Organizations have been making in the last years heavy investments in Web-based distance learning initiatives.
