within-field variation of wheat yield and spatial pattern of weed density and soil nitrogen were evaluated by geostatistical methods. samples were taken from a 90×120 m area located in a 3.8 ha wheat field. soil nitrogen content and weed density at tillering and wheat yield at maturity were measured in 1 m2 plots located at the center of 10×10 m grids. grain yield was varied between 1.5-4.9 t h...
with the introduction of communicative language teaching, a large number of studies have concerned with students’ oral participation in language classrooms. although the importance of classroom participation is evident, some language learners are unwilling to engage in oral activities. this passivity and unwillingness to participate in language classroom discussions is known as “reticence”. rev...
Flax (Linum usitatissimum L.) is an oilseed and widely adapted crop. Oil of regular genotypes of flax is used in industry because of its unique fatty acid profile. New, mutant genotypes of flax have oils similar to sunflower oil which can be used as edible oil. This experiment was conducted to investigate the genetic variation of agronomic traits and productivity in different edible and industr...

In order to evaluate the productivity potential of some bread wheat varieties and promising lines under no-till rainfed condition two different on-farm trials were conducted in cold (Sonqor) and warm (Sarpol-e Zahab) regions of Kermanshah province during 2017-18 cropping season. In the cold condition, 12 winter genotypes and in the warm condition 32 spring genotypes were evaluated for grain ...

TDP‐43 proteinopathy is a kind of neurodegenerative diseases related to the TAR DNA‐binding protein 43‐kDa molecular weight (TDP‐43). The typical include amyotrophic lateral sclerosis (ALS), frontotemporal lobar degeneration (FTLD), Alzheimer's disease (AD), Parkinson's (PD) and so on. As process cannot be blocked or slowed down, these patients have poor quality life prognosis, bring huge burde...
temporomandibular joint ankylosis causes limitation in mouth opening and establishes severe deformity and asymmetry in patient’s face, especially in children. surgery is the only treatment. this study was conducted to compare the effect of two surgical approaches, gap arthropasty and interpositional gap arthroplasty, on rate of maximum interincisal opening in temporomandibular joint ankylosis. ...
the rise and stublishment of safavid dynasty was depend on triangle of tasavof, tashayo and royalty, kings legitimized their power upon these. therefore for the understanding the functions of that period we must explore the role of this elements. although application and emphsise upon dignities such as; complete mentor (morshede kamel), deputy of absent imam (nayebe imame ghayeb), and god’s sha...
this study attempted to explore if teaching english collocations through two different modes of awareness-raising and input flooding has any possible differential effect on immediate retention as well as retention in a delayed assessment. it also compared the possible differential effect of teaching english collocations implicitly and explicitly on actively using the items in writing. m...
