OBJECTIVES To assess whether plate bending at a hole significantly changes the biomechanical properties of a locked screw. METHODS Coronal plane bends of 5-, 15-, or 45-degree angles were placed in 3.5-mm locking compression plates with the apex at a locking hole. An additional 45-degree angle test group was created in which a threaded screw head insert was placed before bending. Ten plates w...
STUDY DESIGN Retrospective review of radiographic data. OBJECTIVES This study sought to define interobserver and intraobserver variability to further delineate reliable means by which radiographs of patients with neuromuscular scoliosis can be examined. SUMMARY OF BACKGROUND DATA Previous studies analyzed the use of Cobb angles in the measurement of idiopathic and congenital scoliosis, but ...
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...
In a trochoidal-type machine, the rotor and chamber will be in direct contact when apex seals arc removed. The reliability and efficiency of the machine will depend on the magnitude of these contact forces. In this paper, a finite element model that simulates the planetary rotation of a rotor inside a chamber is developed. The model is then used to analyze contact forces between rotor and chamb...
