OBJECTIVES Locked plating constructs may be too stiff to reliably promote secondary bone healing. This study used a novel imaging technique to quantify periosteal callus formation of distal femur fractures stabilized with locking plates. It investigated the effects of cortex-to-plate distance, bridging span, and implant material on periosteal callus formation. DESIGN Retrospective cohort stud...

Hardware prominence after plate fixation for clavicle fracture is a common complication. The aim of the study was to perform a 3D analysis of the prominence of different types of superior clavicle plates. An automated fitting of 3 straight and 10 precontoured plates was performed on 52 3D-CT-scan reconstructed cadaver clavicles. The mean and maximum bone-plate distance and maximum prominence wa...

in this study, the possibility of estimating wheat density was investigated by using a non-destructive method of output voltage of the light received by the photovoltaic cells. for the static tests, treatments and procedures, a system was designed and built. an experiment with different density on the wheat crop was carried out. the components of optical system clouding: photocells, led lights ...

Abstract-In FZP’S Spatial resolution and focusing efficiency play very important role for getting good results. There is dependency between resolution and FZP diameter. So I described analytical estimations on radius, diameter etc. This paper presents the dependency of focusing efficiency on (1 order diffraction wave) on number of zone plates, dependency of focusing efficiency on interlayer dis...

casimir forces of massive ferrnionic dirac fields are calculated for parallel plates geometry in spatial space with dimension d and imposing bag model boundary conditions. it is shown that in the range of ma>>l where m is mass of fields quanta and a is the separation distance of the plates, it is equal to massive bosonic fields casimir force for each degree of freedom. we argue this equality ex...

Integrated optical switches using mechano-optical sensing are gaining more attention in many fields due to their fast switching speed, large bandwidth and compact devices. In this paper, a micromachined electrostatically actuated metal plate to sense the evanescent field above the waveguide is presented. The feasibility of MEMS based light weight mechanical plates to achieve fast switching is e...
