let g=(v,e) be a graph with vertex set v and edge set e.for two vertices u,v of g ,the closed interval i[u,v] ,consists of u,v and all vertices lying in some u-v geodesic in g.if s is a set of vertices of g then i[s]is the union of all sets i[u,v]for u,v ? s. if i[s]=v(g) , then s is a geodetic set for g.the geodetic number g(g) is the minimum cardinality of geodetic set.the maximum cardinalit...
هدف این پژوهش، بررسی اثر افزودن همزمان سطوح مختلف روغن اسانسی (ارگواستیم® بر پایه پونه کوهی) و آنزیم بتا-گلوکاناز به جیره ی جوجه های گوشتی تغذیه شده با جیره های بر پایه ی جو و مقایسه ی اثر جیره ها با یکدیگر بر عملکرد، گوارش پذیری مواد غذایی و جمعیت میکروبی دستگاه گوارش و همچنین، مقایسه ی جیره های دارای آنزیم و روغن اسانسی با جیره ی بر پایه ی ذرت-سویا، از نظر عملکرد و هزینه ی خوراک به ازای هر کی...
Methicillin-resistant Staphylococcus aureus is becoming increasingly prevalent as both a nosocomial and a community-acquired pathogen. Daptomycin, a lipopeptide antibiotic now in phase III clinical trials, is rapidly bactericidal in vitro against a range of gram-positive organisms, including methicillin-resistant S. aureus (MRSA). In this study, we compared the efficacy of daptomycin with that ...
در این مطالعه، بیان ژن های کاندید مرتبط با آسیت در جوجه های گوشتی سالم و آسیتی سویه آرین بررسی شده و تغییرات بیان آنها با افزودن مکمل گیاهان دارویی زردچوبه، آویشن و دارچین مورد تحقیق قرار گرفت. آزمایش در قالب طرح فاکتوریل (2×4) با 8 تیمار و 4 تکرار و 25 قطعه جوجه در هر تکرار انجام گرفت. تیمارهای آزمایشی شامل دو سطح انرژی (جیره رقیق و غلیظ) و چهار سطح گیاهان دارویی (عدم وجود گیاه دارویی، g/kg 5 ...
background & aim: this experiment was conducted to examine the effect of different levels of echinacea purpurea (ep) in comparison with an antibiotic (flavofosfolipol) on total antioxidant activity (aoa) in serum of broiler chicks. experimental: in this trial 240 one-day-old broiler chicks (ross 308) were weighed and randomly assigned to the 5 treatment groups, each with 4 replicates with 1...
Histidine is an amino acid precursor of neuronal histamine. It is evident that peripheral injection of histidine produces effects that resemble to centrally administered histamine. The aim of the present study was to compare the effects of intracerebroventricular (ICV) injection of histamine and inraperitoneal (IP) injection of histidine on food intake in rabbits. ICV injections of histamine (1...
to study the effect of urea application in safflower (carthamus tinctorius) and determination of effective traits on its yield, a factorial experiment based on randomized complete block design in three replications was conducted in tabriz, iran, during 2012. studied factors were urea rate levels as 100, 150 and 200 kg/ha and urea application times 100% in sowing time, 50% sowing time + 50% stem...
