in this paper the response modification factor due to ductility and saved strength of cylindrical concrete elevated and ground tanks is obtained using finite element method and nonlinear push over analysis considering the lateral effective modes of tanks. to modeling the behavior of the tank materials, the five parameters william-warnke and prefect elastoplastic models are used for concrete and...

Background In Rheumatoid Arthritis (RA), the presence of rheumatoid factor (RF) indicate poor prognosis. Strategies searching biomarkers that predict response to biologic therapies allowing selection patients with highest chance for are pertinent. Whether RF is a biomarker RTX disputed. [1] Objectives To investigate whether high (3 times normal) predictive good therapeutic in RA treated Rituxim...
