Background and Objectives: The population is aging fragility fractures are a research topic of steadily growing importance. Therefore, systematic bibliometric review was performed to identify the 50 most cited articles in field analyzing their qualities characteristics. Materials Methods: From Core Collection database Thomson Reuters Web Knowledge, influential original with reference were ident...
یکی از روش های ارزیابی لرزه ای پل ها استفاده از منحنی های شکنندگی تجربی است. از اطلاعات خسارت موجود برای برقراری رابطه بین حالت حدی خسارت و مؤلفه های حرکت زمین استفاده می شود. از آنجا که ویژگی های هیچ کدام از حرکت ورودی و مصالح سازه ای نمی توانند به طور قطع بیان شوند، مطالعات آسیب پذیری احتمالاتی با استفاده از روابطی که احتمال خسارت را به صورت تابعی از متغیرهای اتفاقی حرکت زمین و خصوصیات مصالح ...
in vitro antioxidant and erythrocyte protecting activities by aqueous extract of ficus thonningii leaves on blood cells were studied in acetaminophen treated rats. the extract was safe at limit dose of 5000 mg kg-1body weight. the extract demonstrated dose dependent antihemolytic effect at dose levels between 50 and 200 mg kg-1 body weight. the lowest antihemolytic effect was observed at dose l...
This study assessed age-related and gender differences in the relative contribution of fragility and crash over-representation to serious injuries per crash-involved driver in Western Australia. Police-reported crashes for the period 1998-2003 were extracted from the Western Australian Road Injury Database. For each passenger vehicle driver age and gender group, serious injuries per crash-invol...
OBJECTIVE(S) Some but not all studies indicate that individuals with HIV infection are at an increased risk of fracture. We systematically reviewed the literature to investigate whether incidence of fracture (both overall and fragility) differs between individuals with and without HIV. DESIGN A systematic review and meta-analysis. METHODS Medline, Scopus and the Cochrane Library databases f...
Laminopathies, mainly caused by mutations in the LMNA gene, are a group of inherited diseases with a highly variable penetrance; i.e., the disease spectrum in persons with identical LMNA mutations range from symptom-free conditions to severe cardiomyopathy and progeria, leading to early death. LMNA mutations cause nuclear abnormalities and cellular fragility in response to cellular mechanical s...
Abstract Due to technological developments in last decade, new methods of seismic evaluation are use like simulation based, algorithm probabilistic, software based etc. These have enabled researchers move from linear non-linear analysis. Incremental dynamic analysis (IDA) is performance method where a suite ground motions applied structure further scaled particular levels intensity. Seismic fra...
The purpose of this study was to determine whether volar locking plate fixation for distal radius fracture benefits the fragility fracture population as much as it benefits the non-fragility fracture population. This matched case-control study was conducted based on a multi-center clinical prospective cohort. A comparison of treatment outcomes after volar locking plate fixation was made between...
Retrofitted bridge fragility curves provide a powerful tool for assessing the effect of retrofit measures on the seismic performance of different bridge types under a range of loading levels. Traditional methods for retrofit assessment typically evaluate the effectiveness of retrofit based on the performance of individual components. However, the use of fragility curves for retrofitted bridges ...
In this study, an existing hospital structure has been evaluated with incremental dynamic analysis (IDA). This building is accommodated in Karaj with soil type II. At first, two 2-D frames along X, Y direction are selected. Then, five performance levels are determined according to “Rehabilitation Code for Existing Buildings (Publication No. 360) including Immediate Operational (IO), Limited Dam...
