Osseous impingement occurs early in flexion in cam-type femoroacetabular impingement: a 4D CT model.
AIMS The aim of this study was to examine the real time in vivo kinematics of the hip in patients with cam-type femoroacetabular impingement (FAI). PATIENTS AND METHODS A total of 50 patients (83 hips) underwent 4D dynamic CT scanning of the hip, producing real time osseous models of the pelvis and femur being moved through flexion, adduction, and internal rotation. The location and size of t...
Soft tissue damage has been observed in hip joints with pathological geometries. Our primary goal was to study the relationship between morphological variations of the bony components of the hip and resultant stresses within the soft tissues of the joint during routine daily activities. The secondary goal was to find the range of morphological parameters in which stresses are minimized. Computa...
در این پایان نامه، با فرض اینکه v یک *c - مدول هیلبرت تولید شده ی شمارا روی یک $ c^{ast} $,ـ جبر $ a $ است، ثابت خواهیم کرد که دنباله ی $ lbrace f_{i}:iin i brace subseteq v $ یک قاب استاندارد برای $ v $ است اگر و تنها اگر سری $ sum_{iin i} langle x,f_{i} angle langle f_{i},x angle $ برای هر $ xin v $ همگرا (در نرم) باشد و ثابت های $d>0$ و $c $ موجود ب...
For the past 50 years, the Ramachandran map has been used effectively to study the protein structure and folding. However, though extensive analysis has been done on dihedral angle preferences of residues in globular proteins, related studies and reports of membrane proteins are limited. It is of interest to explore the conformational preferences of residues in transmembrane regions of membrane...
