Abstract This study focused mainly on the shifts of the grammatical cohesion in texts translated from English into Persian. It aimed to identify the grammatical cohesive devices (GCDs) in ST and TT separately, based on Halliday and Hassn's Model (1976), determine the number of occurrences of GCDs in two texts and finally, illustrate types of shifts of grammatical cohesion and strategies used in...

Argument maps as schematic representations of arguments and their logical and evidential relationships are effective diagrams for instruction in education as well as in L2 development. However, their use for teaching L2 writing in EFL contexts has not been adequately studied. Therefore, this study investigated the effect of argument mapping instruction on Iranian EFL learners’ writing achieveme...

During meiosis, DNA events of recombination occur in direct physical association with underlying chromosome axes. Meiotic cohesin Rec8 and cohesin-associated Spo76/Pds5 are prominent axis components. Two observations indicate that recombination complexes can direct the local destabilization of underlying chromosome axes. First, in the absence of Rec8, Spo76/Pds5 is lost locally at sites of late...

Twenty-five methicillin-resistant Staphylococcus aureus (MRSA) isolates were characterized by staphylococcal protein A gene typing and the ability to form biofilms. The presence of exopolysaccharides, proteins, and extracellular DNA and RNA in biofilms was assessed by a dispersal assay. In addition, cell adhesion to surfaces and cell cohesion were evaluated using the packed-bead method and mech...

The mononuclear complex [Cu(L)(CH3CN)(PPh3)]ClO4, (1), (L= 2,5-diphenyl-3,4-bis(2-pyridyl)cyclopenta-2,4-dien-1-one), has been synthesized and investigated by elemental analysis, IR, 1H NMR, UV-Vis spectroscopic methods and X-ray diffraction. The complex crystallizes in the non-centrosymmetric space group P212121 in accord with the asymmetric (atropisomer) Cu centre. Its coordination polyhedron...

classical soil mechanics involves the study of fully saturated soils. however, many problems encountered in geotechnical engineering practice involve unsaturated soil, in which behavior is significantly different from classical saturated soil. negative pore pressure and capillary forces develop a virtual cohesion between the grains of semi saturated soils. this kind of cohesion is dependent on ...

Although it has physical effects, temporary landscape as a new issue provides various potentialas a place events that can’t be ignored because of wide range effects on promoting and upgrading the quality ofspace. The purpose of this study is to analyze the status and mechanism of temporary landscape. As a basic andpractical research, it is done by using the correlation method and descriptive-an...
