This paper examines the cyclic performance of reduced beam section (RBS) moment connections incorporating larger member sizes than those allowed in current seismic provisions for prequalified steel connections, through experimentally validated three-dimensional nonlinear numerical assessments. Validations adopted finite element procedures are carried out against experimental results from two te...

We have observed the luminous (L2−10 keV ≃ 6×10 erg s) radio–quiet quasar RBS 1124 (z = 0.208) with Suzaku. We report the detection of a moderately broad iron (Fe) line and of a weak soft X–ray excess. The X–ray data are very well described by a simple model comprising a power law X–ray continuum plus its reflection off the accretion disc. If the inner disc radius we measure (rin 6 3.8 gravitat...

تضعیف عمدی مقطع تیر در نزدیکی محل اتصال به ستون یک راه حل کاربردی برای ایجاد شکل پذیری و توانایی مقاومت در برابر تغییر شکلهای بزرگ چرخه ای در اتصالات قاب خمشی است. با این روش، مفصل پلاستیک در مقطع تضعیف شده تشکیل می گردد و این کاهش موضعی، تقاضای وارده بر روی اجزاء اتصال و احتمال آسیب پذیری آن را کاهش می دهد. بر همین اساس در طرح حاضر اتصال نوین خمشی تیر به ستون با مقطع کاهش یافته توسط جان آکاردئ...

Background/Rationale: The ongoing COVID-19 pandemic has not only affected the physical wellbeing but also mental health of many individuals, including young adults such as medical students. Many factors influence a student’s ability to cope with and grow from stressful experiences, their resilience behaviors traits. Building upon prior studies on post-traumatic growth in studen...

Attributes of both the viral glycoprotein and its cellular receptor play key roles in determining the outcome of infection. This body of work endeavors to illustrate how these two components influence the efficiency of virus infection in in vitro and in vivo systems with an emphasis on characterizing the transduction capacity of a novel entry-targeting glycoprotein. In previous work, the Molone...

رتبه بندی ریسک های یک پروژه به ویژه زمانی که تعداد عوامل ریسک زا افزایش می یابد به عنوان بخشی مهم از فرایند پیچیده مدیریت ریسک محسوب می شود. در این تحقیق نخست ساختار جامعی از ریسک های اصلی پروژه های تونل سازی در قالب 17 دسته اصلی و 196 زیر سطح تهیه شده و سپس این ریسک ها در عملیات تونل سازی سد سیمره در جنوب غرب ایران رتبه بندی شده است. بدین منظور از روش تصمیم گیری گروهی و میانگین وزین جهت جمع آو...

The diffusive behavior of argon in quartz was investigated with three analytical depth profiling methods: Rutherford Backscattering Spectroscopy (RBS), 213 nm laser ablation, and 193 nm (Excimer) laser ablation on the same set of experimental samples. The integration of multiple depth profiling methods, each with different spatial resolution and sensitivity, allows for the cross-checking of met...

Cohesinopathies are human genetic disorders that include Cornelia de Lange syndrome (CdLS) and Roberts syndrome (RBS) and are characterized by defects in limb and craniofacial development as well as mental retardation. The developmental phenotypes of CdLS and other cohesinopathies suggest that mutations in the structure and regulation of the cohesin complex during embryogenesis interfere with g...

A 2.1-kb plasmid was previously isolated from Weissella cibaria KLC140 in kimchi and cloned into pUC19 along with the slpA and gfp genes, resulting in an 8.6-kb pKWCSLGFP construct for use as a novel surface display vector. To reduce the size of the vector, the minimal replicon of pKW2124 was determined. The pKW2124 plasmid contains a putative origin of replication (ori), a potential ribosomal ...
