Background: Lumbar motion analysis is used as a clinical method in the diagnosis and treatment of low back pain (LBP). So far, no studies have shown if manipulating the sacroiliac joint (SIJ) will change spinal kinematics.Objective: The main objectives of this study were to investigate the effects of SIJ manipulation on the lumbar kinematics in subjects with innominate rotation and to compare l...

This paper [1] has been retracted as it is essentially identical in content with the published article " Elucidating of rotation speed in friction stir welding of pure copper: Thermal modeling " published in References [1] M. Jabbari and C. C. Tutum, " Optimum rotation speed for the friction stir welding of pure copper, "

The application specific paper describes a high precision, wide speed rotation sensing approach based on the Universal Frequency-to-Digital Converter (UFDC-1). Such design approach lets significantly simplify the design process, reduce time-to-market and production price and produce tachometers and tachometric systems with high metrological performances and digital self-adaptive smart rotation ...

An urgent task for many enterprises of the petrochemical and fuel energy complex, using pumps, fans compressors in their technological processes, is to increase speed rotation these turbomechanisms. such mechanisms due an productivity. Quite often, obtaining increased both automation devices special equipment.
 
 The purpose study analyze possibility building synchronous motors with a...

We precisely measure the force-free swimming speed of a rotating helix in viscous and viscoelastic fluids. The fluids are highly viscous to replicate the low Reynolds number environment of microorganisms. The helix, a macroscopic scale model for the bacterial flagellar filament, is rigid and rotated at a constant rate while simultaneously translated along its axis. By adjusting the translation ...
