In order to investigate the dynamic response of reinforced concrete spatial frames caused by initial damages, a six-story frame model is analyzed by employing the nonlinear dynamic methodology in accordance with the alternate path method issued by General Services Administration. In this paper, the fiber model and force-based beam-column element are utilized in OpenSees. Four various scenarios ...

A new procedure for deriving nonlinear mathematical modeling for a specific class of aerospace hydro - mechanical control valves is presented. The effects of friction on the dynamic behavior of these types of valves along with the experimental verifictions are also given. The modeling approach is based on the combination of the following three tasks: decomposition of the valve into simple speci...

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 seismic responses of continuous multi-span reinforced concrete (RC) bridges were predicted using inelastic time history analyses (ITHA) and incremental dynamic analysis (IDA). Some important issues in ITHA studied this research, including: the effects artificial natural records on predictions mean demands, displacement directions response, use 2D with combination rules for prediction respon...

Background: Current findings suggest that iron deficiency anemia (IDA) may be a predisposing factor for febrile seizure (FS), while some studies show the lower prevalence of IDA in the children with FS.The present systematic review and meta-analysis aimed to elucidate the association between IDA and FS. Methods: A comprehensive search was performed using MeSH keywords in databases such as PubM...

A conductometric urea biosensor based on sol–gel-immobilized urease on a screen-printed inter-digitated array (IDA) electrode has been developed. The screen-printed thick-film IDA electrode has proven to be an excellent conductometric transducer in which the admittance signal was dominated by the conductance signal and the resulting dynamic range was wide enough to be employed for the construct...

OBJECTIVE This study evaluated the risk of cancer among patients with iron deficiency anemia (IDA) by using a nationwide population-based data set. METHOD Patients newly diagnosed with IDA and without antecedent cancer between 2000 and 2010 were recruited from the Taiwan National Health Insurance Research Database. The standardized incidence ratios (SIRs) of cancer types among patients with I...

Survivin is a member of the inhibitor of apoptosis protein family (IAP) that acts in both inhibition of apoptosis and regulation of the cell cycle. Despite the fact that survivin is overexpressed in almost all human malignancies, its expression is undetectable in most normal adult tissues, which is what makes it a potential target for anticancer interventions. The aim of this work was to invest...
