computational fluid dynamics analysis was employed to investigate the radial flow field patterns of proton exchange membrane fuel cells (pemfc) with different channel geometries at high operating current densities. 3d, non-isothermal was used with single straight channel geometry. our study showed that new generation of fuel cells with circle stack with the same active area and inlet area gave ...
the aim of this study was to evaluate the reproductive efficiency of short and long term treatment with progestagens in addition to pregnant mare serum gonadotropin (pmsg) in arabian ewes during the non-breeding season. a total of 56 ewes were divided into three groups: in group i vaginal sponges (60 mg medroxy progesterone acetate; map) were applied and removed after 6 days; in group ii, vagin...
Supply chain performance evaluation problems are complex problems with multiple criteria and multi-layered internal linking activities. Data Envelopment Analysis (DEA) has been used to evaluate the relative performance of organizational units called Decision Making Units (DMUs). However, the conventional DEA models cannot take into account the complex nature of supply chains with internal linki...
Background: Aim of this study was to compare the clinical and radiological long-term outcomes following operativetreatment of comminuted radial head fractures using 1) primary radial head resection arthroplasty, 2) acute radial headresection, or 3) necessary secondary prosthetic removal. Additionally, we evaluated complex radial head fracturescombined with elbow dislocation and verified the hyp...
