this study aims to understand certain linguistic and semantic resources for the text construction, namely the constructs of cohesion, coherence. the analysis of cohesive ties was conducted on the writing samples of 40 subjects (20 most coherent and 20 least coherent) iranian undergraduates of english. this prompted us to identify the dominant types of cohesive devices used in most coherent writ...

formulaic sequence (fs) is a general term often used to refer to various types of recurrent clusters. one particular type of fss common in different registers is lexical bundles (lbs). this study investigated whether lbs are stored and processed as a whole in the mind of language users and whether their functional discourse type has any effect on their processing. to serve these objectives, thr...

The symmetric core of the nuclear pore complex can be considered schematically as a series of concentric cylinders. A peripheral cylinder coating the pore membrane contains the previously characterized, elongated heptamer that harbors Sec13-Nup145C in its middle section. Strikingly, Sec13-Nup145C crystallizes as a hetero-octamer in two space groups. Oligomerization of Sec13-Nup145C was confirme...

G protein gated inward rectifier potassium (GIRK) channels are gated by direct binding of G protein beta-gamma subunits (Gβγ), signaling lipids, and intracellular Na(+). In cardiac pacemaker cells, hetero-tetramer GIRK1/4 channels and homo-tetramer GIRK4 channels play a central role in parasympathetic slowing of heart rate. It is known that the Na(+) binding site of the GIRK1 subunit is defecti...

the present study is an attempt to find out cultural exophoric references in four common english textbooks, namely touch stone, american file, top notch, and total english series used at iranian english language institutes and to compare the frequency of occurrence of such references in these coursebooks. in order to compare cultural exophoric references used in these coursebooks, the researche...

We report here, the results of molecular dynamics simulation of p-doped (Ga-face)GaN over n-doped (Siface)(0001)4H-SiC hetero-epitaxial material system with one-layer each of Ga-flux and (Al-face)AlN, as the interface materials, in the form of, the total Density of States (DOS). It is found that the total DOS at the Fermi-level for the heavily p-doped (Ga-face)GaN and ndoped (Si-face)4H-SiC het...
