learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...
In a greenhouse research, the effects of soil water conditions, sewage sludge and chemical fertilizers on growth characteristics and water use efficiency of rice (Oryza sativa L. cv. Ali Kazemi) were studied in a loamy sand alkaline non-calcareous soil. The study was performed as a factorial experiment in a randomized complete blocks design including soil water conditions in three levels (conti...
the objective of this research was to study the effects of phenological stages on yield and quality traits in 22 populations of tall wheatgrass agropyron elongatum. a split plot design was conducted using a complete randomized block with two replications in lorestan (borujerd), iran during 2007-2008. the genotypes were cut in five maturity stages as vegetation, stem elongation, heading date, an...
lncrnas (long non-coding rnas) are responsible to control the degradation process, rna stability, orchestration, inhibition, transcription and histone modification etc. these rnas have been termed as the key agents of several mechanisms such as development, organogenesis and regeneration of damaged tissues etc. they interact with a number of partner molecules either protein, rnas or dnas and co...
genetic diversity in bean collection can be used in breeding program for selection of genotype with desirable agronomic traits. fifty two accessions of common bean (phaseolus vulgaris) has been evaluated for genetic diversity of agronomic traits, grain quality and determination of association between grain yield and some morphological traits at research farm of national plant gene bank of iran,...
background: hymenocardia acida is traditionally used in african herbal medicine and has numerous therapeutic benefits. but little is known about its potentially negative effects on pregnant women. objective: the aim of the present study was to evaluate the antifertility effect of aqueous ethanolic extract of hymenocardia acida stem bark in female wistar rats. materials and methods: four groups ...
In order to evaluate the efficiency of biocontrol agents of corn stem borer ,Ostrinia nubilalis, experiment was conducted in a randomized complete block by five treatments and four replication, including, Indoxacarb (Avant)®, Trichogrammawasps, Bacillus thuringiensis var: kurstaki, integration of Trichogramma sp. and Bt., and cont...

In order to evaluate dry matter remobilization to seeds in the winter type rapeseed cultivars grown under drought stress conditions, an experiment was carried out using a randomized complete block design arranged in a split plot with three replicates in Shahre-Qods, Iran, in the 2011-2012 growing season. Irrigation treatments including control (irrigation after 80 mm evaporation from evaporatio...
spermatogonia are the male germ line stem cells whose life long expansion is needed for permanent production of spermatozoa. the present study was designed to examine the effect of hcg treatment on germ cell proliferation following stem cell transplantation in mice. spermatogonial stem cells were isolated from neonatal mice testes and characterized by alkaline phosphatase, immunoreactivity and ...
