The traditional radial flux PMSM and axial have an effective air gap on only one side, between the stator rotor, generates electromagnetic torque. There are defects in magnetic-field utilization, it is difficult to improve torque density. Therefore, this paper proposes axial–radial-flux permanent-magnet synchronous motor (ARF-PMSM), which combines with flux, be used elevator-traction machine-dr...

purpose: to describe the association between optic disc traction and non-arteritic anterior ischemic optic neuropathy (naion). methods: eighty three eyes of 83 patients with naion were evaluated by optical coherence tomography (oct) for detecting vitreous adhesion to the optic nerve head with separation from adjacent retina (partial posterior vitreous detachment). those who were negative for su...

purpose: to evaluate the effect of childhood corneal opacity on the anteroposterior length of the globe in adulthood. methods: twenty-three patients with significant unilateral corneal opacity which had developed before the age of 6 years and the normal fellow eyes (controls) were evaluated. a comprehensive ocular examination including measurement of anterioposterior length and anterior chamber...

OBJECTIVE To determine outcomes after administration of a prone lumbar traction protocol. DESIGN Prospective, longitudinal, case series. SETTING Suburban, chiropractic practice. PARTICIPANTS A total of 296 subjects with low back pain (LBP) and evidence of a degenerative and/or herniated intervertebral disk at 1 or more levels of the lumbar spine. We excluded patients involved in litigatio...

PURPOSE The purpose of this study was to determine the incidence of venous thromboembolism (VTE) after hip arthroscopy. METHODS Over the course of 13 months, four surgeons that routinely perform hip arthroscopy participated in a protocol to screen all patients postoperatively for deep venous thrombosis (DVT) using bilateral venous duplex ultrasound at or about the 2 week postoperative time po...

PURPOSE To identify the risk factors for development of peripapillary retinal splitting (schisis) in patients with glaucoma or suspicion of glaucoma. SETTING Glaucoma Clinic, Department of Ophthalmology, Northwestern University Feinberg School of Medicine, Chicago, IL. METHODS In this institutional cross-sectional study, 495 patients (990 eyes) who had undergone spectral-domain optical cohe...

PURPOSE To evaluate the effect of vitrectomy on the best-corrected visual acuity (BCVA) and postoperative complications in highly myopic eyes with myopic traction maculopathy. METHODS The medical records of 71 eyes of 64 patients with myopic traction maculopathy and high myopia (≤-8.0 diopters and axial length, ≥26.0 mm) were reviewed. Twenty-six eyes had only macular retinoschisis, 30 eyes h...

PURPOSE Football is the most popular high school sport; however, it has the highest rate of injury. Speculation has been prevalent that foot fixation due to high footwear traction contributes to injury risk. Therefore, the purpose of the study was to determine whether a relationship exists between the athlete's specific footwear traction (measured with their own shoes on the field of play) and ...
