Along a non-uniform flow in a stream or river, the pressure, energy, and momentum coefficients tend to vary from section to section. These coefficients also tend to vary with the water depth and discharge. Although some researchers provided some values of these coefficients for special conditions, their spatial variability in accelerated flow has not been adequately investigated. To simplify ca...

Whether a landfill facility is conducting a bioreactor operation with large-scale liquid injection or simply recirculating site-generate leachate, achieving uniform liquid distribution in the waste mass is always a critical operational goal. Several methods of liquid introduction have been adopted by the industry. Of these methods, subsurface lateral injection lines (including perforated plasti...

BACKGROUND Hamstrings loading has previously been shown to increase tibiofemoral posterior translation and external rotation, which could contribute to patellofemoral malalignment and elevated patellofemoral pressures. The current study characterizes the influence of forces applied by the hamstrings on patellofemoral kinematics and the pressure applied to patellofemoral cartilage. METHODS Ten...

This study investigates geometrical non-linear analysis of composite circular cylindrical shells under external pressure over part of their surfaces and also shells subjected to combined axial compression and triangular external pressure. Donnell non-linear shell theory along with first order shear deformation theory (FOSD) are adopted in the analysis. In the case of combined axial compression ...
