asthma, juvenile diabetes mellitus, or cancer. As described by the authors, most studies have focused on main effects, with varied results. Either investigators did not consider potential moderating variables or the samples in these studies were too small to test meaningfully for interactions. With increasingly limited resources in the age of “managed care,” individual differences in responses ...
Forming Limit Diagrams are useful tools for evaluation of formability in the sheet metals. In this paper the effects of yield criteria on predictions of the right and left-hand sides of forming limit diagrams (FLDs) are investigated. In prediction of FLD, Hosford 1979, “Karafillis-Boyce” (K-B) and BBC2000 anisotropy yield functions have been applied. Whereas the prediction of FLD is based on th...
LTRAVIOLET irradiation produces dimers of thymine, thymine-cytosine and cytosine in deoxyribonucleic acid (DNA) (BEUKERS, IJLSTRA and BERENDS 1960; WACKER, DELLWEG and WEINBLUM 1960; SETLOW, CARRIER and BOLLUM 1965). UV light inactivates transforming DNA and induces thymine dimers in a parallel manner, as if the dimers block transforming activity (SETLOW and SETLOW 1962). Thymine dimers and thy...
پژوهش حاضر با هدف تجزیه و تحلیل رفتارهای استنادی فارغالتحصیلان دو گروه آموزشی فنی مهندسی و علوم انسانی، سالهای1380- 1385، براساس مآخذ پایاننامههای موجود در کتابخانة پژوهشگاه اطلاعات و مدارک علمی ایران انجام شده است. روش پژوهش پیمایشی بوده و با بهکارگیری روش تحلیل استنادی، منابع و مآخذ 400 پایاننامه از هر دو گروه آموزشی، که از طریق نمونهگیری تصادفی طبقهای انتخاب شده بودند، مورد بررسی قرا...
Abstract Most concepts to characterize crack propagation were developed for elastic materials. When applying these methods elastomers, the question is how inherent energy dissipation of material affects cracking behavior. This contribution presents a numerical analysis growth in natural rubber taking due visco-elastic behavior into account. For this purpose, experimental tests first carried out...
This article presents a very detailed study on the mechanical characterization of highly nonlinear material, immature equine zona pellucida (ZP) membrane. The ZP is modeled as visco-hyperelastic soft matter. Arruda–Boyce constitutive equation and two-term Prony series are identified most suitable models for describing hyperelastic viscous components, respectively, ZP’s response. Material proper...
THE STRESS RESPONSE SYSTEM (SRS) has a central role in orchestrating physical and psychosocial development of both humans and nonhuman species (Ellis, Jackson, & Boyce, 2006; Korte, Koolhaas, Wingfield, & McEwen, 2005). For many organisms, the SRS contributes crucially to responding flexibly to environmental opportunities and challenges. One of the most remarkable features of the SRS is the wid...
