An earthquake with the magnitude of 5.9 Mw occurred in Qeshm Island and Hormozgan province in November 27th 2005. 3D co-seismic deformation field caused by the earthquake are determined based on the ascending and descending interferograms and azimuth offsets. The peak to peak estimated displacement is about 10 cm in west, 69 cm in north and 22 cm in vertical directions. We apply strain analysis...

A numerical study that focuses on the maximum displacement response of reinforced concrete structures subjected to earthquake loading is presented. The specific item of the interest is the increase in maximum displacement caused by biaxial base excitation as compared with that for uniaxial base excitation. The maximum displacement of structural systems structures subjected to uniaxial base exci...

The objective of the present study was to evaluate the diagnostic efficiency of ultrasound (US) and magnetic resonance imaging (MRI) in the diagnosis and differential diagnosis of mammary duct ectasia (MDE) and breast cancer. This retrospective study was performed on 35 patients with MDE and 105 patients with breast cancer using US and MRI. Imaging features, semi-quantitative and quantitative p...

BACKGROUND Major depression is one of the strongest known risk factors for suicide. However, of the estimated 8.5 million adults with serious thoughts of suicide in the past year, only half had a major depressive episode (MDE). Identifying risk factors for suicide in the absence of depression may provide additional targets for prevention and intervention. This study uses nationally representati...

BACKGROUND The objective of this study was to determine whether major depressive episodes (MDE) contribute to a lower rate of participation in three prevention activities: blood pressure checks, mammograms and Pap tests. METHODS The data source for this study was the Canadian National Population Health Survey (NPHS), a longitudinal study that started in 1994 and has subsequently re-interviewe...

Steel Plate Shear Wall (SPSW) is an emerging seismic load-resistant system that, compared to other systems, enjoys the advantages of stable ductile behavior, fewer detailing requirements, rapid constructability, and economy. American seismic provisions decree that a SPSW should be designed as a moment frame with a web infill plate. Specifically, in case of buildings taller than 160 ft, it decre...

Earthquake-induced crustal deformation and ground shaking can alter stream flow and water levels in wells through consolidation of surficial deposits, fracturing of solid rocks, aquifer deformation, and the clearing of fracture-filling material. Although local conditions affect the type and amplitude of response, a compilation of reported observations of hydrological response to earthquakes ind...

The design earthquake motion is often defined by response spectra. To check the seismic capacity of designed structures, however, it is necessary to perform dynamic analysis using earthquake motion (time history) which is compatible with the design spectra. In this regard, the phase characteristic of earthquake motion is one of the most important issues in addition to that of the amplitude char...
