Does a small size needle puncture cause intervertebral disc changes?
PURPOSE Small size needles have been regularly used for intradiscal injection of innocuous/potential therapeutic compounds in experimental conditions, but also in clinic procedures, such as discography. Our aim was to investigate if a 30-gauge needle could trigger observable changes on intact intervertebral discs. We compared these effects to those induced by a large size needle (21-gauge), a w...
متن کاملMicromixing in a Rotor–Stator Spinning Disc Reactor
This paper presents the micromixing times in a rotor-stator spinning disc reactor. Segregation indices are obtained at different rotational speeds performing the Villermaux-Dushman parallel-competitive reaction scheme. Consequently, the corresponding micromixing times are calculated using the engulfment model, while considering the self-engulfment effect. It was found that the segregation index...
متن کاملSimulation of fully coupled thermomechanical analysis of disc brake rotor
Vehicle braking system is considered as one of the most fundamental safety-critical systems in modern vehicles as its main purpose is to stop or decelerate the vehicle. The frictional heat generated during braking application can cause numerous negative effects on the brake assembly such as brake fade, premature wear, thermal cracks and disc thickness variation (DTV). In the past, surface rough...
