in a retrospective study the clinical presentations, neurological findings, contrast studies, operative findings, and the follow-up results of 314 patients with disc herniation were studied over a 10-year period. this disease was most frequent between the ages of 30 to 40 and mostly in males. low back pain with or without radicular pain was the most frequent symptom, involving the left leg in t...

background & aim: low back pain is broadly documented as one of the most widespread pathologies in the advanced domain. although the reasons of low back pain are uncountable, it has been meaningfully related to intervertebral disc degeneration. present therapies for intervertebral disc (ivd) degeneration such as physical therapy and spinal fusion reduce symptoms' severity, but do not treat the ...

introduction: due to limitations of current treatments for degenerative disc disease, arthroplastic methods to repair the diseased disc have been proposed. the artificial disc is a mobile implant for degenerative disc replacement that attempts to lessen the degeneration of the adjacent elements following interbody fusion procedures. because the success of artificial disc replacement depends on ...

This paper studies the interest of the integration of battery energy storage with Static Synchronous Compensator (STATCOM) for improving the low voltage ride through capability (LVRT) of a fixed speed wind turbine connected to the grid. For this reason and by applying a grid fault, a comparison is made between integrating the SSSC, the STATCOM and the STATCOM with battery energy storage. The sy...

purpose : to investigate the impact of socioeconomic factors on presenting severity of glaucoma methods : in a cross-sectional study at farabi eye hospital, and during 12 months study period, 258 patients with newly diagnosed glaucoma were enrolled and socioeconomic status of the patients were evaluated. results : lower socioeconomic score was associated with higher intraocular pressure (r=-0.3...

Abstract The paper reports on the development and application of a swept Langmuir probe to characterize plasma between two disc-like electrodes. A battery was added circuit offset against cathode fall voltage, make sweep voltage effective at tip. This arrangement allowed collection electron ion parts current subsequent construction time-resolved current–voltage I P (V) characteristics with time...

Batteries are omnipresent, and with the uprise of the electrical vehicles will their use will grow even more. However, the batteries can deliver their required power for a limited time span. They slowly degrade with every charge-discharge cycle. This degradation needs to be taken into account when considering the battery in long lasting applications. Some detailed battery models that describe t...

0740-7475/01/$10.00 © 2001 IEEE March–April 2001 THE ACTIVITY OF SEVERAL COMPONENTS in a computing system is event-driven. For example, the activity of display servers, communication interfaces, and user interface functions is triggered by external events, and it is often interleaved with long, idle periods. An intuitive way to reduce average power dissipated by the whole system consists of shu...

Background & Importance: Disc herniation is defined as the prolapsed of material disc into the spinal canal. If the disc fragment is free in spinal canal, it is called sequestration disc fragment. Occasionally, alteration in sequestration disc fragment makes the diagnosis of the disc herniation, challenging. Case Presentation: We reviewed a rare case of the cervical sequestrated disc...
