textbooks play a crucial role in language learning classrooms. the problem is that among the great quantity of available textbooks on the market which one is appropriate for a specific classroom and a group of learners. in order to evaluate elt textbooks, theorists and writers have offered different kinds of evaluative frameworks based on a number of principles and criteria. this study evaluate...
چکیده طراحی سلولی یک مسأله پیچیده است که عوامل متفاوتی همانند شکل سلول، نوع آنتن، تعداد آنتن ، ارتفاع آنتن ، تراکم جمعیت و غیره در آن مؤثر است. منطقه ی تحت پوشش سلول، فاکتور بسیار مهمی برای پشتیبانی از مشتریان است و طراحی سلولی مناسب، می تواند پوشش مورد نظر طراحان را تضمین کند. این طراحی با روش های کلاسیک به سادگی میسر نیست، در این پروژه سعی شده است با استفاده از الگوریتم ژنتیک علاوه بر یافتن ...
In this paper, we introduce the Steiner Bi-objective Shortest Path Problem. This problem is defined on a directed graph G=(V,A), with subset T?V of terminals. Arcs are labeled travel time and cost. The goal to find complete set efficient paths between every pair nodes in T. motivation behind stems from data preprocessing for vehicle routing problems. We propose solution method based labeling ap...
Abstract Background and Objective: the Formation of urinary infection by uropathogenic E.coli needs numerous virulence factors and biofilm formation is among these factors. Bacteria that form biofilms express phenotype traits that appear according to the bacteria type. Cellulose is an important compound on the outside of E.coli causing bacte...
This paper investigates some unexplored ambivalences of Strawson's distinction between the participant stance marked by reactive attitudes and objective in which such are deemed inappropriate. First, a recipient-oriented agent-oriented reasons for taking is introduced. These both practical rooted agent's position. The former category refers to recipient's capacities moral agency, latter interes...
objective: to study the mechanisms involved in amyloid formation processes, we made a mammalian cell culture model of amylin aggregation and characterized its properties. materials and methods: amyloid fibrils were extracted from cho cells and binding affinity to thioflavin t and congo red was investigated. then the apple-green birefringence of extracted fibrils was detected under polarized li...
Background and Objective: Melanoma is the most deadly type of skin cancer that has a high potency and rapid metastasis to other organs. It appears that cancer stem cells (CSCs) are responsible for invasion and metastasis. The aim of this study was to investigate the expression of cancer stem cells candidate markers and their association with stemness features in mel...
