Background: Objectives To study the relationship between 2019 EULAR/ACR classification criteria and organ damage in patients with systemic lupus erythematosus (SLE) Methods Patients involved a cross-sectional validation of judged by panel rheumatologists to be clinical SLE were studied. Those who fulfilled at their last clinic visit stratified into 2 groups based on cut-off score 20. The intern...

The present paper focuses on the study of some of the fundamental aspects of the cooperative brittle phenomena and damage growth. This rather complex problem is studied on a simple discretized artifice known as the parallel bar model. The disorder in microstructure is introduced by a statistical description of the distribution of the link rupture strengths. The criteria of the damage growth are...

Seismic safety of liquid storage tanks is of considerable importance due to its application in different industries. In Iran, most of these storage tanks are designed based on API650 code provisions. Despite designing tanks according to API standard, the lesson learned from previous earthquakes, shows different kind of damage occurring on them. This study is an investigation on evaluating diffe...

A continuum damage model for the prediction of the onset and evolution of intralaminar failure mechanisms and the collapse of structures manufactured in fiber-reinforced plastic laminates is proposed. The failure mechanisms occurring in the longitudinal and transverse directions of a ply are represented by a set of scalar damage variables. Crack closure effects under load reversal are taken int...

evaluating the population density and spatial pattern of infected trees are one of the important criteria for selecting the management method and epidemiology of forest diseases. this study aimed at assessing the damage intensity and spatial-temporal mortality patterns of oak in qoroq forest park, golestan province. the health of oak trees was evaluated in seven transects by using quarter-point...
