Background: Chondromalacia patella is the most common cause of mechanical knee pain in young women. Q angle and knee alignment are important clinical parameters for biomechanics of the patellofemoral joint. Objective: To identify the prevalence of knee malalignment and to find out if there is a correlation between knee mal alignment and Q angle with age at onset of disease. Methods: All pa...

among the most important sources of competitive advantage, is creating and developing strategic alignment competency. strategic alignment, literally, is an abstract and qualitative concept. and a qualitative concept while not been quantified and operationalized, does not worth paying attention practically. this article basing on a general formula and taking systems dynamics approach, suggests a...

objective: adverse surface interactions between one-bottle adhesives and chemical-cured composites may occur with delayed light activation of light-cured composites. the purpose of this study was to assess the effects of delayed activation of light-cured composites on shear bond strength of two one-bottle adhesives with different acidity to bovine dentin. materials and methods: flat dentin surf...

background: delayed graft function is a main complication after deceased donor kidney transplantation that adversely affects graft outcome. difficulties in prediction and early detection of delayed graft function have hindered the ability to perform proper therapeutic interventions. we investigated whether measuring urinary interleukin 18 and neutrophil gelatinase-associated lipocalin as marker...

floorplanning is an important step in physical design of vlsi circuits. it is used to plan the positions of a set of circuit modules on a chip in order to optimize the circuit performance. however, modern floorplanning takes better care of providing extra options to place dedicated modules in the hierarchical designs to align circuit blocks one by one within certain bounding box for helping seq...

introduction lung herniation following blunt chest trauma is extremely rare and only a few hundred cases of this pathology have been reported in the english language medical literature. this type of lung hernia is divided into intercostal, parasternal, or supraclavicular subtypes based on the exact location of the chest wall defect. traumatic intercostal lung hernia is even more uncommon. delay...
