The Finite Element Method (FEM) has been used in the broad field of continuum mechanics in engineering disciplines for several decades. However, recently, some scholars have attempted to apply the method to social science phenomena. What is the scope of using FEM in social science-related fields? Anchored in the literature on social sciences, this paper, firstly, reviews the scope of using FEM ...
Patients suffering from the acute respiratory distress syndrome (ARDS) requires thoracic electrical impedance tomography (EIT) for the monitoring their conditions ranging from dynamic shifting of body fluids to lung aeration right at the bedside. More objectively, EIT-derived numeric parameters would help the physician to evaluate the state of the lung. Thus, here we have performed a Finite Ele...
The present work shows the material flow analysis in indentation by the numerical two dimensional Finite Elements (FEM) method and the experimental two-dimensional Digital Image Correlation (DIC) method. To achieve deep indentation without cracking, a ductile material, 99% tin, is used. The results obtained from the DIC technique depend predominantly on the pattern conferred to the samples. Due...
This paper describes the isolation and characterization of 16 mutations in the germ-line sex determination gene fog-2 (fog for feminization of the germ line). In the nematode Caenorhabditis elegans there are normally two sexes, self-fertilizing hermaphrodites (XX) and males (XO). Wild-type XX animals are hermaphrodite in the germ line (spermatogenesis followed by oogenesis), and female in the s...
In the embryo, hypoxemia causes redistribution of cardiac output from the periphery toward the heart and the brain. In view of this, we investigated developmental changes in the contractile and relaxing properties of the peripheral femoral artery (Fem) and the more central carotid artery (Car) at 0.7, 0.8, and 0.9 of the chicken embryo incubation time. Isolated arteries were studied in myograph...
rs4340 polymorphism at intron 16 of the angiotensin-converting enzyme (CD143) gene was reported to repress cough reflex by reducing bradykinin and substance P levels, thus increasing the likelihood to develop pneumonia. There have been different reports regarding the correlation of CD143 rs4340 genotypes with pneumonia risk, which prompted us to perform a meta-analysis to determine the elusive ...
مصالح چندجنسی مانند خاک، سنگ، بتن آسفالتی و بتن سیمانی، یا بصورت طبیعی وجود دارند و یا ساخته ی دست بشر هستند. اجزاء تشکیل دهنده ی این مواد غیریکنواخت بوده و شامل کانی ها ، خاکه ها ، ماسه، شن، سنگ، فضاهای خالی و ترک ها می باشند. هر یک از این اجزاء، خصوصیات فیزیکی و مکانیکی مشخصی تحت بارگذاری خارجی دارند. بررسی ادبیات فنی موجود آشکار می کند که (1) بطور کلی ناهمگنی مصالح چندجنسی نقش مهمی در تعیین ...
در طی سالیان اخیر، تلاشهایی برای حذف شبکه از فرآیندهای حل عددی صورت گرفته که نتیجهی این تلاشها ایجاد گروهی از روشهای محاسباتی به نام روشهای بدون شبکه بوده است. در بین روشهای بدون شبکه، روشهای MLPG ، یکی از روش-های مؤثر و موفق در حل مسایل مختلف به شمار میآیند. در این پژوهش، الگوریتم بدون شبکه MLPG ، برای شبیهسازی و مدلسازی تنشهای حرارتی و مکانیکی در حین فرآیند جوش نقطهای و همچنین تن...
It has been technically challenging to effectively model and simulate elastic deformation of spline-based, thin-shell objects of complicated topology. This is primarily because traditional FEM are typically defined upon planar domain, therefore incapable of constructing complicated, smooth spline surfaces without patching/trimming. Moreover, at least C1 continuity is required for the convergenc...
