this study investigated the effect of prior knowledge on the listening comprehension performance of fl learners. twenty students, male and female, drawn from the two intact groups of the senior and junior english language and literature majors were chosen as the participants of this study . the two groups were then randomly assigned into the experimental and control group. the experimental gr...
Migrating neuronal growth cones exert traction forces that are generated by ATP-driven F-actin/myosin interactions. Sustained generation of these forces may require an energy supply mediated by the guanidino kinases, creatine kinase and arginine kinase. We cloned and sequenced grasshopper arginine kinase and examined its expression during embryogenesis and its subcellular localization in vivo a...
هدف از انجام این تحقیق بررسی نقش احتمالی داروهای نیتریک ارژیک در اثرات پاداشی نیکوتین در موش بزرگ آزمایشگاهی نر بود. از یک روش ترجیح مکان شرطی شده یا cpp (conditioned place preference) برای اندازه گیری اثرات پاداشی نیکوتین استفاده شد و در روز تست علاوه بر نمره شرطی شدن تعداد رفتارهای وابسته به دوپامین نیز شمارش شد. نتایج نشان داد که تجویز داخل صفاقی نیکوتین باعث القای cpp معنی دار شد در حالی که...
Arginine is one of the essential amino acid involved in numerous biosynthetic pathways that significantly influence tumor growth. It has been demonstrated that arginine is effective to inhibit proliferation of cancer cells when an appropriate dose is applied. Generally, induction of cell death requires high concentration of arginine while low concentration of arginine facilitates cell prolifera...
introduction: nutrition and health during the first days of life has critical effect on broiler chickens performance. it is well known that diet formulation based on digestible nutrients is superior to formulation based on total nutrients. the suitable supply of essential amino acids in broilers’ diets requires proper knowledge on their metabolic effects in the body. the excessive or unbalanced...
Pigs suffer up to 50% embryonic and fetal loss during gestation and exhibit the most severe naturally occurring intrauterine growth retardation among livestock species. Placental insufficiency is a major factor contributing to suboptimal reproductive performance and reduced birth weights of pigs. Enhancement of placental growth and function through nutritional management offers an effective sol...
in this thesis, a structured hierarchical methodology based on petri nets is used to introduce a task model for a soccer goalkeeper robot. in real or robot soccer, goalkeeper is an important element which has a key role and challenging features in the game. goalkeeper aims at defending goal from scoring goals by opponent team, actually to prevent the goal from the opponent player’s attacks. thi...
