rested on sociocultural theory (sct), this study attempted to examine the effect of written corrective feedback (wcf) followed by producing written languaging on developing writing accuracy over new tasks. to this aim, two intact iranian efl classes at the low-intermediate level were randomly assigned to two experimental groups: direct (n = 25) and indirect (n = 25). both groups wrote on a numb...
background: coccidiosis of domestic fowl, caused by species of the genus eimeria , is responsible for important economic losses in poultry production. because different species and/or strains can vary in pathogenicity and other biological parameters, their precise characterization is important for epizootiological studies. methods: fifty samples from litter, whole intestinal tract and feces w...
this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...
the anamorphic fungus genus periconia is worldwide in distribution and causes foliar disease on plants mostly in tropical and subtropical regions. this study presents the description and illustration of p. palmivora discovered on leaves of phoenix dactylifera (palmae/arecaceae) from terai forest region of uttar pradesh, india. the taxonomic determination was based on morphological characteristi...
this paper is an attempt to fill all of previous literature of coccinellidae records and species distribution in different provinces of iran. distribution was extracted for each species from literatures. there are 6 subfamilies, 16 tribes, 32 genus and 117 species in iran. the largest subfamily, tribe and genus in iran were scymninae, scymnini and scymnus, respectively. the most distribution wa...
Plant parasitic nematodes of Dorylaimida occur only in the Longidoridae. Longidorus is one of important genera in this family, which it,s species are parasite on many plants and act as a vector for some of plant viruses. From 1999 to 2001, more than 250 soil samples were collected from several localities of Iran. Nematodes were extracted, fixed (De Grisse, 1969) and mounted on glass slides in d...

abstract the laelapidae is a large family with worldwide distribution. many laelapids are ectoparasitic on small mammals or associated with arthropods, although some species are free living and predators especially in soil habitat; also they are common in stored products. during three years (2007-2009) of faunestic survey, samples were collected from different habitats such as soil, plant litte...
Pedicularis L. (Orobanchaceae) is a large hemiparasitic genus, distributed mostly over boreal and arctic-alpine regions of the northern hemisphere. In the present study 9 species of the genus that are reported in flora of Iran, were undertaken for stigma morphological study and numerical analysis. The stigmatic surface is even in P. pycnantha and P. wilhelmsiana, is expanded into a subspherical...
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...
