the effect of the utilization of electronic dictionaries on depth and breadth of vocabulary knowledge: a case of iranian efl learners
مطالعه حاضر تلاشی است برای بررسی تأثیرات به کارگیری فرهنگ لغات ، یکی از مهمترین ابزارهای یادگیری واژگان درفراگیری زبان خارجی، بر روی دانش لغوی. دراین تحقیق فرهنگ های الکترونیکی در قیاس با فرهنگ های چاپی مورد بررسی قرارگرفته اند که آیا این فرهنگ ها تاثیرقابل توجهی بر روی دوبعد کمی و کیفی دانش لغوی یعنی عمق و گستره لغات می گذارند. همچنین مشخص گردیده است که آیا تفاوت قابل ملاحظه ای میان عمق و گستر...

background: global findings indicate that incidence rate of cutaneous leishmaniasis (cl) has significantly increased during the past decade, as documented in many countries. this review was aimed to evaluate the trend of cl cases in terms of demographic and clinical characteristics during a decade after the earthquake (2003–2012) compared to the corresponding period before the earthquake in b...
متن کاملA variable depth search branching
We introduce a variable depth search branching, an extension to the local branching for solving Mixed-Integer Programs. Two strategies are assessed, a best improvement strategy and a first improvement strategy. The extensive computational assessment evidences a significant improvement over the local branching for both strategies.

متن کاملCrustal Earthquake Instability in Relation to the Depth Variation
Recent stability studies using constitutive relations of the type found by Dieterich, Ruina. and others to describe frictional slip of rocks in the laboratory have provided a new explanation of the depth cutoff of shallow crustal earthquakes. The class of friction laws discussed has the property that the sliding stress depends on normal stress. temperature, slip rate, and slip history. For slid...
