RIGIDITY OF THE SPINAL COLUMN

investigation of effective parameters on the rigidity of light composite diaphragms (psscb) by fem

در این رساله با معرفی سقف های psscb متشکل از ترکیب ورق های فولادی ذوزنقه ای و تخته های سیمانی الیافی به عنوان سقف های پیش ساخته (سازگار با سیستم سازه ای قاب های فولادی سبک) به بررسی پارامترهای موثر بر صلبیت سقف، پرداخته می شود. در تحقیق حاضر ابتدا به مدل سازی دو نمونه سقف آزمایش شده، به روش اجزاء محدود با استفاده از نرم افزار تحلیلی abaqus ver 6.10 پرداخته شده است. نمونه های ساخته شده تحت اعما...

Movements of the lumbar spinal column.

Dynamic CT scanning of spinal column trauma.

Dynamic sequential computed tomographic scanning with automatic table incrementation uses low milliampere-second technique to eliminate tube cooling delays between scanning slices and, thus, markedly shortens examination times. A total of 25 patients with spinal column trauma involving 28 levels were studied with dynamic scans and retrospectively reviewed. Dynamic studies were considerably fast...

An Anatomical Study of the Human Spinal Column

Since the work of Schmorl" in 1927, there has been growing interest in the study of the various degenerative changes associated with the aging process in the spinal column, especially in the intervertebral discs. The earlv developmental anatomy of the spinal column has received special attention in the attempt to explain some of these degenerative changes. This paper deals with a study of these...

A Case Fracture—Dislocation of the Cervical Spinal Column

On July 7tli, 1893, Kali, a Hindu labourer, aged about 27, was admitted to the Monghyr Hospital, with the history that a large bag of salt had fallen on the back of his head. At the time of his admission he had complete paralysis of the muscles of the lower limbs, abdomen and thorax and back.
