PURPOSE To evaluate dynamic changes in iris configuration and their association with anterior chamber angle width by using anterior segment optical coherence tomography (ASOCT). METHODS Forty-six normal subjects with open angles and 40 with narrow angles (Shaffer grade < or =2 in three or more quadrants during dark room gonioscopy) were analyzed. The dynamic ASOCT dark-light changes of iris b...

when belief priniplees among all muslems became identi cal, this opportunity has bee provided for clergyman scientist to infere legal command ments to rely it, that it lead to emergence of prudence religion and diversity of opinions. although this practice religious leads to dispute about opinions, but they are not related to beliefe principles. thus it isn&apos;t worthy that these disputes don...

Bowing of the interventricular septum (IVS) is a sign of severe pulmonary embolism(PE); however, it is affected by high interobserver variability. The aim of the study was to evaluate the application of volumetric reconstructions of the right ventricle for assessment of IVS position regarding its accuracy in identifying right ventricular dysfunction, as well as interobserver agreement in evalua...

The aim of this study was to address, in normal knees, the variability of posterior offset of femoral condyles and tibial slope, and the presence of any correlation between the two that might be needed to achieve an adequate joint motion in flexion. Magnetic resonance images of normal knees of 80 subjects, 45 males and 35 females, with a mean age of 38.9 years, were analysed. Measurements were ...

This paper presents the results of a recent study of common violin bowing techniques using a newly designed measurement system. This measurement system comprises force, inertial, and position sensors installed on a carbon fiber violin bow and electric violin, and enables recording of real player bowing gesture under normal playing conditions. Using this system, performances of six different com...

The mechanics of music making is important both in preventing injuries and in guiding how music is performed and taught. Electromyography (EMG) measures muscle activity patterns and has been shown to be a useful resource in understanding the loads involved in instrumental playing; however, only a small number of projects have been undertaken, and little is understood on the muscle activity used...

We present theoretical and experimental results for the band gap of InxGa1−xN alloys, showing significantly larger bowing than has been commonly assumed. We highlight the importance of properly including strain in the experimental analysis. Using X-ray diffraction (XRD) and Rutherford backscattering spectrometry the layers in our study were determined to be pseudomorphically strained. The In co...

We report 2 adult cases where the diagnosis of acute plastic bowing of the forearm was either delayed or missed. In a 21-year-old man, ulnar bowing was missed and fixation was not performed because the patient had no limitation to his range of movement or pain. In a 24-year-old woman, the presentation of bowing in both the ulna and radius was delayed and corrective osteotomy was necessary for r...

We have carried out a radiostereometric study of 50 patients (54 knees) with osteoarthritis of the knee who were randomly allocated to receive a cemented or a hydroxyapatite-coated femoral component for total knee replacement. The patients were also stratified to receive one of three types of articulating surface (standard, rotating platform, Freeman-Samuelson (FS)1000) all based on the Freeman...
