Coronary stents improve resting blood flow and flow reserve in the presence of stenoses, but the impact of these devices on fluid dynamics during profound vasodilation is largely unknown. We tested the hypothesis that stent implantation affects adenosine-induced alterations in coronary hemodynamics and wall shear stress in anesthetized dogs (n = 6) instrumented for measurement of left anterior ...
Vascular functions, including tissue perfusion and peripheral resistance, reflect continuous structural adaptation (remodeling) of blood vessels in response to several stimuli. Here, a theoretical model is presented that relates the structural and functional properties of microvascular networks to the adaptive responses of individual segments to hemodynamic and metabolic stimuli. All vessels ar...
Downslope soil movement along riverbanks is a significant erosion process. Plant roots, particularly of woody vegetation, apparently stabilize soil on slopes because in most areas where the vegetation is removed, frequent bank failure occurs. Plant roots increase soil-shearing resistance both directly by mechanical reinforcement and indirectly through removal of pore water by transpiration. In ...
In this paper, resistance spot welding process of AISI 201 stainless steel is studied experimentally. For this purpose, effect of welding current on quality of weld is investigated and relationships between welding current and fusion zone characteristics are examined. For determining mechanical properties such as maximum load and fracture mode, tensile - shear test of spot welds is performed. ...

Coupling shear wall has been highly considered in recent years. Due to architectural limitations, sometimes the architect is forced to use two spans separate from shear wall. The study results have shown that using coupling shear wall will have better results than single wall in structure behavior and the desired performance can be achieved by using thinner plates. Coupling steel shear wall has...

Cone penetration resistance in sands with fines contents up to 35% is explored through drained cylindrical cavity expansion simulations with a modified MIT-S1 constitutive model. The constitutive model is calibrated to sands with 0%, 10%, 20%, and 35% low-plasticity fines with data from constant volume direct simple shear, drained and undrained triaxial compression, shear wave velocity, and 1D-...
