Abstract With the increased use of cable bolts in mining and civil projects worldwide, it is important to understanding performance these support structures different scenarios. The axial load transfer mechanisms six were investigated experimentally this research study. A large-scale pull-out testing apparatus with a capacity 1000 kN was designed manufactured as part investigation. common comme...

UNLABELLED First carpometacarpal osteoarthitis is frequent and surgery may be necessary if medical treatment is not efficient. Trapeziometacarpal arthroplasty, trapeziometacarpal arthrodesis and trapezectomy may be proposed. These surgical solutions may modify the carpometacarpal kinematics of the thumb. However, no clinical tools are currently available to assess these modifications. The goal ...

BACKGROUND Obtaining accurate measurements of scoliosis from two-dimensional (2-D) radiographs can be challenging because of the three-dimensional (3-D) nature of the deformity. Previous studies have shown that the sagittal plane, in particular, is misrepresented on 2-D radiographs because of the influence of axial plane rotation. The purpose of the current study was to define a methodology for...

A comprehensive, geometrically accurate, nonlinear C0-C7 FE model of head and cervical spine based on the actual geometry of a human cadaver specimen was developed. The motions of each cervical vertebral level under pure moment loading of 1.0 Nm applied incrementally on the skull to simulate the movements of the head and cervical spine under flexion, tension, axial rotation and lateral bending ...

Objective: To describe the possibility of rotation of the vermis as the cause of enlarged posterior fossa in the fetus. Methods: Eight women were referred to our ultrasound unit for evaluation of enlarged posterior fossa with suspected agenesis of the vermis on axial plane. All women underwent thorough ultrasound evaluation, including demonstration of the posterior fossa on midsagittal plane wi...

Farm youth commonly perform animal care tasks such as feeding and watering. The purpose of this study was to determine the effects of age, bucket size, loading symmetry, and amount of load on upper body moments during carrying tasks. Fifty-four male and female participants in four age groups (8-10 years, 12-14 years, 15-17 years, and adults, 20-26 years) participated in the study. Conditions in...
