شوری یکی از مهمترین فاکتورهای محدود کننده تولید محصول و جوانه زنی بذر گیاهان مرتعی در مناطق خشک و نیمه خشک می باشد. هدف از این مطالعه ارزیابی اثر استرس شوری با nacl روی صفات جوانه زنی، رشد نهال، عناصر معدنی و خصوصیات فیزیولوژیکی avena sativa و avena fatua بود. طرح آزمایشی کاملا تصادفی 5 سطح استرس شوری ، صفر، 80، 120، 160، 200 میلی مولار nacl در 4 تکرار و 50 عدد بذر در هر تکرار در شرایط ژرمیناتو...
Background and Aim: Presence of ischemic changes on the anterior surface of heart and AV block worsen the prognosis of acute Inferior Mycocardial Infarction (MI). The rate of mortality increases with the occurrence of AV block in inferior MI.The aim of this study was to predict and diagnose acute Inferior MI in patients with AV block based on ECG and clinical features.Patients and Methods: ...
This paper presents a robust speech recognition technique called audio-visual speech fragment decoding (AV-SFD), in which the visual signal is exploited both as a cue for source separation and as a carrier of phonetic information. The model builds on the existing audio-only SFD technique which, based on the auditory scene analysis account of perceptual organisation, works by combining a bottom-...
abstract: introduction & objective: in patients with chronic renal failure who need chronic hemodialysis, av fistula is one of the most proper ways of vascular access. the aim of this study was to assess the patency and complications of av fistulas in patients with chronic hemodialysis. materials & methods: in this descriptive study 82 patients with chronic renal failure, who underwent av fistu...
Introduction: The aim of the present study was to determine direct effects of NO modulation on protective electrophysiological properties of atrioventricular node (AV node) in the experimental model of AF in rabbit. Methods: Isolated perfused rabbit AV nodal preparations were used in two groups. In the first group (N=7), LNAME (50μM) was applied. In the second group (N=12), different concent...
The paper proposes a new metadata model (VandA) directed to support innovative exploitation of Historical AV Archives content. After an analysis of the needs of traditional and potential users, the model is illustrated through running examples to show at what extent the new usages can be supported.

Objective(s): Biodegradable polymers are featured with notable potentials for biotechnology and bioengineering purposes. Still, there are limitations in their applicability so that in many cases composite forms are used. The present study is focused on chitosan (CS), gelatin (GEL), honey (H) and aloe vera (AV) for preparation of thin films.Methods: To prepare the thin film, CS and GEL wit...
