abstract since heubners (1985) pioneering study, there have been many studies on (mis) use/ non-use of articles by l2 learners from article-less and article languages. the present study investigated how persian l2 learners of english produce and interpret english definite descriptions and demonstrative descriptions. it was assumed that definite and demonstrative descriptions share the same cen...
there is less published research about how teachers in efl contexts respond to students who are relatively less mature and less competent l2 writers. while writing researchers have examined various issues concerning peer and teacher response in writing-oriented classes, little research has centered on the effect of collaborative tasks particularly dictogloss on writing skills. output collaborat...
the purpose of this study was to investigate the relationship between family functioning and marital adjustment humor couples are due to the nature and objectives of the research and application of methods for its implementation correlation was used. the study population consisted of all the couples in the city who uses random cluster sampling of 200 students were selected as sample. data from ...
Understanding the combined effects of sowing patterns and nitrogen (N) management strategies on crop productivity, environmental costs, economic benefits is important to ensuring sustainable development dryland agriculture. Thus, we conducted a three-year field experiment explore two spring maize (FS, flat sowing; RFPM, ridge furrow plastic film mulching) four N (N0, no fertilizer; N1, normal u...
(Aims) To clarify the mechanisms though which dense planting could alleviate negative effect of reducing N rate on yield, (Methods) an experiment with four nitrogen levels—0 (N0), 120 (N1), 180 (N2) and 240 (N3) kg ha−1—and three plant densities—180 (D1), (D2) 300 (D3) × 104 basic seedlings ha−1—was conducted. (Results) Increasing density decreased root length, volume, surface area tips individ...
The Lamé curve is an extension of ellipse, the latter being a special case. Dr. Johan Gielis further extended in polar coordinate system by introducing additional parameters (n1, n2, n3; m): rφ=1Acosm4φn2+1Bsinm4φn3−1/n1, which can be applied to model natural geometries. Here, r radius corresponding angle φ; A, B, n1, n2 and n3 are estimated; m positive real number that determines angles curve....
We study the periodic solutions of the generalized Abel equation x′ = a1A1(t)x 1+a2A2(t)x 2+a3A3(t)x n3 , where n1, n2, n3 > 1 are distinct integers, a1, a2, a3 ∈ R, and A1, A2, A3 are 2π-periodic analytic functions such that A1(t) sin t,A2(t) cos t, A3(t) sin t cos t are πperiodic positive even functions. When (n3−n1)(n3−n2) < 0 we prove that the equation has no nontrivial (different from zero...
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...
in the name of allah , the compassionate the merciful abstract shath ( blasphemic utterace made during spiritual ) is a complicated concept that deserves reflection in gnosticism and sufism ( mysticism ) and estem and westem scholars have alwaya paid attention to it. although principal essence of gnostic belief is the holy divine law ,gnosticism has pure and unique thoughts . by glancing at t...
to investigate the appropriate distribution of nitrogen fertilizer application and optimum amount of phosphorus fertilizer to achieve high quality and quantitative yield in edible and seed potato (solanum tuberosum l.) tubers, this experiment was conducted in research farm of the college of agriculture and natural resources, university of tehran in 2012. the experiment was performed a strip spl...
