Direct displacement based design (DDBD) is a conceptual framework that directly design a structure to achieve an expected performance level under specified seismic intensity. In this study, two important issues relevant to torsional response of mass eccentric 8-story RC building designed with DDBD approach are investigated. These issues are including the effects of unbalanced mass distribution ...

Introduction: It has been shown that joint click, an initial and common finding in internal derangement (ID), respond to neither conservative treatment nor surgical intervention. This raises the question as to whether it must be treated in the absence of other pertinent signs and symptoms, so the aim of this study was to investigate and compare the MRI findings of TMJ in both normal subjects an...

Displacement Coefficient Method (DCM) stipulated in the ASCE 41-06 standard is becoming the preferred method for seismic rehabilitation of buildings in many high-seismic-hazard countries. Applications of the method for non-building constructions such as bridges are beyond the scope of this standard. Thus its application to this kind of structure should be approached with care. Target displaceme...

Red blood cell (RBC) deformability has a significant impact on microcirculation by affecting cell dynamics. Despite previous studies that have demonstrated the margination of rigid cells and particles in vitro, little information is available on the in vivo margination of deformability-impaired RBCs under physiological flow and hematocrit conditions. Thus, in this study, we examined how the def...

AIM To determine the temporal retinal vessel angle in babies and its relation to preterm birth. METHODS Digital images were obtained during routine screening for retinopathy of prematurity (ROP). The temporal retinal vessel angle was measured in 164 eyes of 82 babies born "very preterm" (24-27 weeks gestational age (GA)), "preterm" (28-31 weeks GA), and "near term" (>/=32 weeks GA). RESULTS...

The ideal stent must fulfil a broad range of technical requirements. Stents must be securely crimped onto the delivery balloon and, in this form, must have a low profile and be sufficiently flexible to facilitate deliverability to the lesion site without distortion or displacement. Following expansion, stents must exert sufficient radial force on the vessel wall to overcome lesion resistance an...

Hartley, Craig J., Anilkumar K. Reddy, Sridhar Madala, Mark L. Entman, Lloyd H. Michael, and George E. Taffet. Noninvasive ultrasonic measurement of arterial wall motion in mice. Am J Physiol Heart Circ Physiol 287: H1426–H1432, 2004; 10.1152/ajpheart. 01185.2003.—Despite the extensive use of genetically altered mice to study cardiovascular physiology and pathology, it remains difficult to quan...

Ultrasound has been widely employed in food industry, while some of its working parameters are usually neglected to be described in its application, which caused the difficulty of reproducing and comparing the results obtained by different groups. So it is definitely not sufficient to simply state the ultrasound conditions such as ultrasound power, frequency and t...

SUMMARY Numerical simulation of fluid-structure interaction (FSI) in the arterial system is a challenging and time consuming procedure because of the intrinsic heterogeneous nature of the problem. Moreover, in patient-specific simulations, modeling of the vascular structure requires parameter identification still difficult to accomplish. On the other hand, new imaging devices provide time seque...

introduction dominant process in arid and semi-arid region is dynamic of wind that carries the sand and caused damage to several facilities and human settlements. there are many human settlements with low population and mostly small and scattered in different parts of foothills of dasht-e lut (lut desert), especially in mountainous margins of alluvial fans. residential and cultivation area of t...
