The objective of this study was to investigate whether it is possible to use a lateral (profile) photograph to determine the underlying skeletal Class and which reference points of the angle of convexity are most suitable for this purpose. Profile photographs and lateral cephalographs included in the baseline data for 180 orthodontic patients were retrospectively evaluated. The subjects were as...

Human gait recognition is a developing biometric engineering now a days. It perceives the individual from its walk and above all from a distance without subject’s cooperation. As human gait recognition system is influenced by diverse view variations effects. So, in this paper we have proposed a human gait recognition strategy for the images caught from distinctive viewing edges (0, 45, 90 degre...

The goal of this investigation is to study the effect of wing sweep angle on the horizontal wing-body- tail configurations in subsonic flow. For this purpose, a series of wind tunnel tests were conducted on a model having a moveable horizontal tail and a wing planform with different sweep angles. Tests were performed at different tail deflection angles. Static surface pressure distribution over...

Background Isometric tunnel placement for anterior bundle of the medial collateral ligament (MCL) reconstruction is mandatory for successful surgery. Purpose This study aimed to demonstrate a useful method for identifying isometric tunnel placement using a single computed tomography (CT) scan. Study Design Descriptive Laboratory Study. Methods Five normal elbows were scanned at 4 differen...

Introduction: Previous surveys have been conducted of the Venusian and lunar impact crater populations in an effort to empirically determine the onset angle of various oblique impact forms. Those surveys showed a general consistency with predictions from small-scale experiments [1,2,3]. That previous work also showed that in the presence of a dense atmosphere the onset angle increases for vario...

Objectives: To compare bilateral standard glenohumeral range of motion, humeral torsion & torsion-corrected motion within and between healthy adolescent baseball pitchers who have an injury to the throwing elbow. Secondarily, analyze relationship angle rotational in pitchers. Methods: Baseball aged 13-17 were prospectively enrolled into either a group, if currently pitching community withou...

During locomotion over land, vertebrates' limb bones are exposed to loads. Like most biological structures, limb bones have a capacity to withstand greater loads than they usually experience, termed a safety factor (SF). How diverse are limb-bone SFs, and what factors correlate with such variation? We have examined these questions from two perspectives. First, we evaluated locomotor SF for the ...

osteochondritis dissecans (ocd) is a common joint disorder in knee, ankle and elbow, however it can be rarely found in glenohumeral joint. in this study, we report an asymptomatic case of humeral head ocd, which was detected incidentally following a trauma. x-rays showed an area of lucency around an oval bony fragment measuring about 1 cm on the superior aspect of the humeral head. however, the...

T-condylar fracture of distal humerus in young children is very rare. Pure physeal fractures of the olecranon are also rare. We report on an extremely rare case of concomitant ulecranon fracture, ipsilateral segmental humerus and intercondylar humerus fracture (type III) in a skeletally immature patient.

In this work computational models are developed to analyze bone remodeling of the humerus after a shoulder arthroplasty using either a cemented or press-fit stem. Bone is modelled as a porous material, characterized by its local density. The bone remodelling model is based on a global optimization criterion by the minimization of a function which takes into account both structural stiffness and...
