Resting state brain networks (RSNs) are spatially distributed large-scale networks, evidenced by resting state functional magnetic resonance imaging (fMRI) studies. Importantly, RSNs are implicated in several relevant brain functions and present abnormal functional patterns in many neuropsychiatric disorders, for which stress exposure is an established risk factor. Yet, so far, little is known ...
three medium magnitude events happened inside the transitional border of south alborz and central iran; namely kahak-qom 2007/06/18 event with ml 5.6, zanjan 2008/05/27 event with ml 5.3 and aradan-garmsar 2007/11/19 event with ml 5.1. this provides us the opportunity to compute focal mechanism and stress drop of the events and compare them with those events happened within the alborz range.
Stressors contribute to thrombosis and insulin resistance. Since obesity-related adipose inflammation is also involved in these pathological states, we assumed that stress correlates with adipose inflammation. Male mice were subjected to 2-week intermittent restraint stress. Expression of plasma lipids, monocyte/macrophage markers (CD11b, CD68, and F4/80), proinflammatory cytokines (monocyte ch...
Introduction and purpose: Based on the data of the statistics center, the elderly population of Iran is growing. Considering the occurrence of major changes in the lives of the elderly and the high prevalence of stress, anxiety and depression in the elderly population, the effect of coloring mandala designs on the mental health of the elderly referring to Yas Day Rehabilitation Center for the E...
اجزا بدنه خودرو عموما در معرض بارهای نامتناسب قرار دارند. از آنجا که تخمین عمر اجزا سازه و بدنه خودرو عموما به تغییر وزن و شتاب خودرو و هزینه ساخت و مسائل ایمنی و استحکام و عمر سازه منتهی می گردد، در صنایع طراحی و ساخت خودرو از اهمیت ویژه ای برخوردار است. تئوری های ارائه شده در این زمینه عموما برای اجزاسازه ای تحت بارهای بسیار ابتدایی سینوسی و هندسه اولیه ارائه شده اند، به گونه ای که عمر قطعات ...
The zero-stress state of a blood vessel has been extensively studied because it is the reference state for which all calculations of intramural stress and strain must be based. It has also been found to reflect nonuniformity in growth and remodeling in response to chemical or physical changes. The zero-stress state can be characterized by an opening angle, defined as the angle subtended by two ...
Background and Objective: Preterm delivery has considerable social, economical and mental effects on neonate and related family. Factors predisposing to, and preventing preterm delivery are still not clearly recognized. However some studies have shown psychological factors to play some role. This study was conducted to evaluate the effect of anxiety in inducing preterm delivery. Materials and M...
Background. Anxiety plays a major role when it comes to sports performance, not only mentally, but physically as well. Objectives. The study aimed to examine the effect of a soccer tournament on baseline anxiety [Spielberger State-trait anxiety inventory questionnaire (STAI), mood [Incredible Short POMS questionnaire (ISP)] and cortisol (saliva sampling) states. Methods. Eight sportswomen’s (...
An analytical method for predicting elastic–plastic stress distribution in a cylindrical pressure vessel has been presented. The vessel material was a ceramic/metal functionally graded material, i.e. a particle–reinforcement composite. It was assumed that the material’s plastic deformation follows an isotropic strain-hardening rule based on the von-Mises yield criterion, and that the vessel was...
