A viscoplastic deformation model considering material damage is used to predict hot tear formation in a permanent mold magnesium alloy casting. The simulation model calculates the solid deformation and ductile damage. The viscoplastic constitutive theory accounts for temperature dependent properties and includes creep and isotropic hardening. Ductile damage theory is used to find mechanically i...

Antioxidant and immunomodulatory effects of anthocyanins are abundant in berberry fruits suggesting that they may have beneficial effects on inflammatory bowel diseases (IBD). The present study was carried out to investigate the anti-colitic effect of Berberis vulgaris fruit extract (BFE) compared to berberine chloride (BEC) and corticosteroids using an animal model of acetic acid induced exper...

This paper presents comparative assessment of the performance characteristics of two optimization algorithms, namely a deterministic nonlinear least squares (NLS) optimization and a stochastic adaptive simulated (ASA) annealing global optimization, implemented in the context of a two-stage structural damage severity estimation approach. First, both the standard NLS and global ASA optimization a...

Despite the large loads placed upon constrained acetabular liners, little is known of their mechanical performance. We analyzed retrieved liners to determine wear and other damage modes and assess associations between types and severity of damage and clinical, radiographic, and implant variables. Outer rim impingement frequency and severity were higher than that for the inner rim. The 20 degree...

Clinical and biochemical data obtained from 163 patients who had taken an overdose of paracetamol were examined to determine which factors or measurements were of value in predicting the severity of ensuing liver damage early after ingestion of tablets. Although the overall severity of hepatic necrosis was found to increase with the dose of paracetamol ingested, correlation was not sufficiently...

background: treating inflammatory bowel disease (ibd) with antidepressants might be of utility to improve patient’s condition. the aim of this study was to assess the efficacy of duloxetine on depression, anxiety, severity of symptoms, and quality of life (qol) in ibd patients. materials and methods: in a randomized, double-blind, controlled clinical trial on  2013-2014, in alzahra hospital (is...

background: in order to describe the patients and evaluate the effectiveness of treatments for widow spider envenomation, investigators require a reliable assessment tool. in this paper, the development of a clinical index for measuring the widow spider bite severity, latrodectus envenomation severity score (less), is described. methods: according to the valid methods for index development, a d...

background: multiple sclerosis (ms) is a neurological disease with fatigue as most prevalent symptom. psychopathological symptoms, physical and mental dysfunctions and body mass abnormalities potentially could deteriorate fatigue. thus, in this study, we aimed at evaluating the effect of these factors on fatigue severity of ms patients. methods: in this cross-sectional study, 162 patients with ...
