the aim of this study is to examine the difference between the introverts and extroverts in preferred advice-giving style. furthermore, it explores the difference between l1 (persian) and l2 (english) regarding the giving of advice for the extroverts and introverts separately. it investigates whether an extrovert or introvert gives advice in the same manner in his l1 (persian) and l2 (english) ...

Background: In plant breeding program to produce hybrid varieties, pair of male sterile and restorer fertility lines are required. Differentiation of lines possessing restorer fertility allele from the lines lacking it remove the need for the progeny test, and thus reducing the time and the cost in the hybrid production procedure. Canola breeding program in Iran has concentrate...

The spectrum of the 0++, 0−−, 1−+ and 1+− heavy-light hybrids have been calculated in HQET. The interpolated current of the hybrid is chosen as gq̄γαG a αμT hv (x), gq̄γαγ5G a αμT hv (x) and gq̄σμαG a αμT hv (x). Some strong couplings and decay widths of the heavy-light hybrids to B(D)π are calculated by using the QCD sum rules. The mass of 0++ hybrid with gluon in TM(1−−) or TE(1+−) mode is found...

Gene flow between populations that are adapting to distinct environments may be restricted if hybrids inherit maladaptive, intermediate phenotypes. This phenomenon, called extrinsic postzygotic isolation (EPI), is thought to play a critical role in the early stages of speciation. However, despite its intuitive appeal, we know surprisingly little about the strength and prevalence of EPI in natur...
