Failure of the resurfaced femoral head may occur in the short term owing to femoral neck fracture or in the long term owing to aseptic loosening as a result of strain shielding. Resurfacing arthroplasties are not all the same. In particular, there is considerable debate regarding the role of the metaphyseal stem and cementing technique. This study examines the influence of various metaphyseal s...
BACKGROUND Some studies have previously shown that geometry of proximal femur can affect the probability of fracture and type of fracture. It happens since the geometry of the proximal femur determines how a force is applied to its different parts. In this study, we have compared proximal femur's geometric characteristics in femoral neck (FNF), intertrochanteric (ITF) and Subtrochanteric (STF) ...
In order to evaluate the effect of medium and spraying calcium nano-fertilizer on quality of cut gerbera flowers, an experiment was conducted as factorial in completely randomized design with 7 media and 3 calcium nano-fertilizer concentrations with 3 replications. The media included cocopeat + perlite (1:1), peat moss + perlite (1:1), mushroom compost + perlite (1:1), peat moss + cocopeat + pe...
Introduction: Human anatomy is essential for both clinical and surgical practice. Although the anterior jugular veins (AJVs) are of great importance in many surgeries, there few studies addressing anatomic variations these vessels. This study highlights venous drainage head neck anatomical AJVs. Objective: To observe describe evaluate whether patterns influenced by anthropometric factors or com...
AIMS To investigate whether aneurysm shape and extent, which indicate whether a patient with ruptured abdominal aortic aneurysm (rAAA) is eligible for endovascular repair (EVAR), influence the outcome of both EVAR and open surgical repair. METHODS AND RESULTS The influence of six morphological parameters (maximum aortic diameter, aneurysm neck diameter, length and conicality, proximal neck an...
In modern society, life expectancy is steadily increasing, at the same time, number of medial femoral fractures increasing. The bone-beam system proximal epiphysis femur has areas different density throughout, however, these differences are most clearly observed in neck. aim stidy was to build a two-dimensional parametric model human neck study its bone and beam structure. Material methods. car...
in solvo-hydrothermal method, xrd pattern was indicated presence of intermediate of ammonium octatmolybdate and ammonium tetramolybdate, which were changed to stble phase of ?-moo3 annealing. sem images were indicated nanoparticle with semispheical morphology and tem image was demonstrated nanoparticles with a diameter size of 25nm. also in impregnate method. the xrd pattern was shown high crys...
Turbulent breakup in emulsification devices is a dynamic process. Small viscous drops undergo sequence of oscillations before entering the monotonic deformation phase leading to breakup. The turbulence-interface interactions prior reaching critical are therefore essential for understanding and modeling This contribution uses numerical experiments characterize critically deformed state (defined ...
Objective: To investigate the three-dimensional reconstruction technique and intraoperative postural changes in the interventional treatment of cerebral aneurysm. Methods: A total of 52 cases involving patients with a definite CT diagnosis of cerebral aneurysm in our hospital were selected from July 2014 to August 2015. The cases were randomly and equally divided into observation and control gr...
