Trains of action potentials in hippocampal pyramidal neurons are followed by a prolonged afterhyperpolarization (AHP) lasting several seconds, which is attributable to the activation of a slow calcium-activated potassium current ((sI)AHP). Here we examine the location of (sI)AHP on CA1 pyramidal neurons by comparing it with two GABAergic inhibitory postsynaptic currents (IPSCs) with known somat...
In spite of The uncontrolled exploitation of groundwater that has caused a sharp drop in water level, Agricultural, industrial and urban activities enter contaminant to various aquifers. Due to Dehgolan plain importance in water supply of industrial, drinking and agriculture, for the vulnerability assessment DRASTIC model was used. The DRASTIC model uses seven environmental parameters (Depth ...
چکیده این تحقیق با هدف پهنهبندی آسیبپذیری آبخوان مرند با استفاده از روشهای DRASTIC، AVI و مقایسه پهنهبندی در سه روش مذکور انجام شده است. روش DRASTIC از ترکیب هفت مشخصه هیدروژئولوژیک قابل اندازهگیری و مؤثر در انتقال آلودگی به آبهای زیرزمینی تشکیل شده است. روش AVIنیز دارای دو مشخصه است. نتایج حاصل از روش DRASTIC تقریباً کاملترین شاخص برای ارزیابی میزان آسیبپذیری آبهای زیرزمینی است که مح...
Analytical hierarchy process (AHP) as multiple criteria decision making tools can be used in the problems with spatial nature like selection of construction contractor. In this study the application of AHP and its weakness and strength and ultimately the fuzzy modified analytical hierarchy process (FAHP) is proposed after the concept of fuzziness, uncertainty and vagueness. A triangular fuzzy u...
BACKGROUND Nurses have long been relied as the major labor force in hospitals. Featured with complicated and highly labor-intensive job requirement, multiple pressures from different sources was inevitable. Success in identifying stresses and accordingly coping with such stresses is important for job performance of nurses, and service quality of a hospital. Purpose of this research is to identi...
مدلهای DRASTIC و SINTACS جزو پرکاربردترین روشهای ارزیابی آسیبپذیری آبهای زیرزمینی به شمار میروند، اما ضعف عمدۀ این دو مدل، اعمالنظرهای کارشناسی برای نرخبندی پارامترهای بهکاررفته در آنهاست. از این رو، هدف اصلی این تحقیق، اصلاح هر دو مدل از طریق فرایند تحلیل سلسلهمراتبی (AHP) بر اساس شرایط هیدروژئولوژیکی محلی دشت اندیمشک است، تا بدین ترتیب بتوان به نتایج نسبتاً صحیحتری از وضعی...
in this study, the vibration behavior of functional graded (fg) circular and annular nanoplate embedded in a visco-pasternak foundation and coupled with temperature change is studied. the effect of in-plane pre-load and temperature change are investigated on the vibration frequencies of fg circular and annular nanoplate. to obtain the vibration frequencies of the fg circular and annular nanopla...
BACKGROUND/AIM Almond hull is produced in high amounts and mostly used as livestock feed. This study was designed to examine the impact of almond hull powder (AHP) administration on lipid profile and antioxidant activities in plasma and liver in hyperlipidemic rats. MATERIALS AND METHODS As the first step, the antioxidant capacity and radical scavenging activity of AHP were determined using c...
The purpose of this paper is to extend the theory of Hierarchies Consistency Analysis (HCA) to establish a multiple structures evaluation model for the AHP. Traditionally, the AHP process is based on a single evaluation hierarchy, according to statistics and group decision theories, a more objective evaluation will be obtained if we can compromise several estimates. We will construct several di...
