در این مقاله به دنبال بررسی ارتباط میان متغیرهای ساختاری و عملکردی در 140 صنعت ایران هستیم. در این تحقیق به بررسی ساختار بازارهای صنعتی بر مبنای شاخص نسبت تمرکز چهار بنگاه و شاخص مزیت هزینه ای و پس از آن به برآورد سطح کارایی صنایع در کد چهار isic بر مبنای رویکرد مرز تصادفی پرداخته شده و با محاسبه سطح کارایی صنایع، ارتباط ساختار و عملکرد در قالب یک الگوی scp بررسی شده است. همچنین برای قضاوت دقیق...
BACKGROUND There are growing interests in using various methods including traditional and complementary medicines (T&CM) for tobacco control. The study aimed to introduce how traditional Korean medicine (TKM) applied to smoking cessation programmes in Korea and to show the detail information of each programme for designing other smoke cessation programmes. METHODS Reports of the smoke cessati...
A major gap in our knowledge of rapid hepatic HDL cholesterol clearance is the role of key intracellular factors that influence this process. Although the reverse cholesterol transport pathway targets HDL to the liver for net elimination of free cholesterol from the body, molecular details governing cholesterol uptake into hepatocytes are not completely understood. Therefore, the effects of ste...
the set covering problem (scp) is a well-known combinatorial optimization problem. this paper investigates development of a local branching approach for the scp. this solution strategy is exact in nature, though it is designed to improve the heuristic behavior of the mixed integer programming solver. the algorithm parameters are tuned by design of experiments approach. the proposed method is te...
Single cell protein (SCP) is the definition for dried cells originated from single-celled organisms intended to be used as a protein source in human foods or animal feeds. An experiment has been conducted to evaluate the various levels of single cell protein on fecal microflora and productive traits of broiler chickens. A total of 192 day-old Ross 308 male chicks were randomly divided into 4 tr...
Introduction: Investigations in rodents as well as in vitro experiments have suggested an anabolic influence of specific collagen peptides (SCP) on bone formation and bone mineral density (BMD). The goal of the study was to investigate the effect of 12-month daily oral administration of 5 g SCP vs. placebo (CG: control group) on BMD in postmenopausal women with primary, age-related reduction in...
مهمترین هدف در پرتودرمانی درمان قطعی تومور و حفظ بافت های سالم مجاور است. به دلیل لازم است اختلاف بین دوز تجویز شده و دوز منتقل شده به تومور کمتر از 2 درصد باشد. به منظور محاسبه دوز تومور، خروجی دستگاه پرتو درمانی برای یک میدان مرجع (2cm1010) اندازه گیری می شود. هدف از انجام این تحقیق بررسی ضرورت استفاده از ضرایب پراکندگی برای تبدیل خروجی میدان مرجع به خروجی سایر میدان های مورد استفاده در پرت...
Use of efficiency measures as a proxy for performance to test the market structureconduct-performance (SCP) hypothesis is explored. Utilizing Battese and Coelli specification, we estimate stochastic frontier production function and SCP equations with output and efficiency measures as endogenous variables. An empirical application to U.S. trucking carries over the period 1994-2003 with emphasis ...
INTRODUCTION Factor (F) XI supports both normal human hemostasis and pathological thrombosis. Activated FXI (FXIa) promotes thrombin generation by enzymatic activation of FXI, FIX, FX, and FV, and inactivation of alpha tissue factor pathway inhibitor (TFPIα), in vitro. Some of these reactions are now known to be enhanced by short-chain polyphosphates (SCP) derived from activated platelets. Thes...
This Article focuses on the Situational Crime Prevention (SCP) approach in criminology, which expands the crime reduction role well beyond the justice system. SCP sees criminal law in a more restrictive sense, as only part of the anticrime effort in governance. We examine the " general " and " specific " responses to crime problems in the SCP approach. Our review demonstrates that the most seri...
