Este trabajo propone y evalúa una trayectoria hipotética de aprendizaje (THA) para los conceptos conjunto generador espacio generado. La THA se diseñó siguiendo el planteamiento Simon (1995), la heurística diseño modelos emergentes mecanismo reflexión sobre relación actividad-efecto. Se realizó un experimento con estudiantes universitarios evaluar si contribuyó al esperado conceptos. Para ello,...

Total hip metal arthroplasty (THA) constitutes an important proportion of the standard clinical implant usage in Medical Physics and Biomedical Engineering. A computational nonlinear optimization is performed with two commonly materials Metal-on-Metal (MoM) THA. Namely, Cast Co-Cr Alloy Titanium. The principal result numerical determination K adimensional-constant parameter model. Results from ...

in most of the sugar beet cultivated areas including kermanshah, iran, late season irrigation is cut- off earlier than usual which causes drought stress in the crop. since root yield still increses in sept. and oct. these areas, withholding irrigation in this period reduce root yield and quality of sugar beet. for this reason, an experimente was conducted during 2004- 2005 based on split plot d...

BACKGROUND The objective of this study was to compare clinical and radiological outcomes of total hip arthroplasty (THA) between ankylosing spondylitis (AS) of the hip joint and avascular necrosis (AVN) of the femoral head. METHODS Thirty patients (30 hips) underwent cementless THA for AS between 2003 and 2012. They were compared to 30 patients (30 hips) who underwent the same procedure for A...

The study sought to ascertain the incidence rates and risk factors for 30-day post-operative complications after primary total hip arthroplasty (THA). Complications were categorized as systemic or local and subcategorized as major or minor. There were 17,640 individuals who received primary THA identified from the 2006-2011 ACS NSQIP. The mortality rate was 0.35% and complications occurred in 4...

INTRODUCTION Rheumatoid arthritis (RA) is one of the major indications of total hip (THA) or knee (TKA) arthroplasty. International studies have suggested that RA is a risk factor for prosthesis infections. OBJECTIVES To compare patients with RA and patients with osteoarthritis (OA) of other etiologies with regard to the incidence of prosthesis, incisional, and other systemic postoperative in...

Quality of life index (Quality Of Well-Being [QWB]) was used to calculate the costs per quality of well year (QWY) in total hip arthroplasty (THA) and compare it to other interventions. Ninety-eight primary and/or revision THA were reviewed. Patients had minimum 1-year follow-up. Quality of life index was used to calculate the costs per QWY in primary and revision THA. Preoperative QWB for prim...
