abstract previous studies on willingness to communicate (wtc) have shown the influence of many individual or situational factors on students’ tendency to engage in classroom communication, in which wtc has been viewed either at the trait-level or situational level. however, due to the complexity of the notion of willingness to communicate, the present study suggests that these two strands are ...
Epistasis and genetic variance heterogeneity are two non-additive genetic inheritance patterns that are often, but not always, related. Here we use theoretical examples and empirical results from earlier analyses of experimental data to illustrate the connection between the two. This includes an introduction to the relationship between epistatic gene action, statistical epistasis, and genetic v...
در این مطالعه، محیط کلریمتریک آنتی بیوگرام که در دانشگاه الزهرا طراحی گردیده است با محیط quicolor شرکت سالوبریس آمریکا و محیط مولر هینتون آگار مقایسه گردید. الگوی حساسیت صد جدایه انترو باکتریاسه با شش آنتی بیوتیک مختلف مشخص گردید. توافق هر سه روش با آنالیزکاپا بررسی گردید. با ده بار تکرار تست حساسیت آنتی بیو تیکی دو سوش استاندارد و دو جدایه بالینی از خانواده انتروباکتریاسه، در هر سه محیط مقادیر...

a characteriation of continuity of the $p$-$lambda$-variation function is given and the helly's selection principle for $lambda bv^{(p)}$ functions is established. a characterization of the inclusion of waterman-shiba classes into classes of functions with given integral modulus of continuity is given. a useful estimate on modulus of variation of functions of class $lambda bv^{(p)}$ is found.
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
