چکیده مقاله:

Pleosporaceae is an important Dothideomycetes family. To elucidate relationships among some selected anamorphic pleosporalean taxa, their Internal Transcribed Spacer (ITS) and RNA polymerase second largest subunit (RPB2) were sequenced and compared. Phylogenetic analyses of both ITS and RPB2 regions were almost similar and generally congruent with previously described phylogenies and morphology based classification schemes. ITS was inefficient to show the taxonomic placement of some species, especially Alternaria species; but RPB2 was appropriate for this purpose.

phylogenetic relationships of anamorphic form of some pleosporalean genera based on analysis of its rdna and rpb2

anamorphs of pleosporaceae are important plant pathogenic fungi. despite efforts to clarify phylogenetic relationships of this group there is still uncertainty about taxonomic position of some genera. therefor to elucidate relationships among anamorphic form of some pleosporalean taxa, the internal transcribed spacer (its) and rna polymerase second largest subunit (rpb2) of some members were de...

on translation of phatic communion and socio-cultural relationships between the characters of the novels

phatic communion is a cultural concept which differs across cultures. according to hofstede (2001), the u.s. tends to have individualistic culture; however, asian countries tend to have collectivistic cultures. these cultures view phatic communion differently. in individualistic cultures like u.s., phatic communion reflects speakers’ socio-cultural relationships in conversations. to see whether...

some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
