The sharing of the wireless spectrum is a major concern of network administrators. Access points in the same network interfere with each other, degrading the aggregate performance of stations. Moreover, wireless networks usually coexist with others applications that share the same spectrum and negatively impact the packet transmission. To overcome these(More)
Objective: The objective of this work was to comparatively evaluate of the use of ethanol (E) with glutaraldehyde (GDA) to inhibit the calcification of porcine pulmonary valvar heterografts (PPVH) implanted in the right ventricle outflow tract of young sheep. Method: Ten young sheep were used, divided into two similar groups: the GDA (Control) Group and the(More)
We evaluated the capacity of tomato juice agar (V8 agar) to differentiate Candida dubliniensis from Candida albicans based on chlamydospore production. Candida albicans (n= 93) and Candida dubliniensis (n= 26) were studied; 100% of Candida dubliniensis showed chlamydospores and in 92.5% of Candida albicans isolates these elements were absent. These results(More)
PURPOSE To determine reproducibility of the femoral condyle cartilage volume (CV) in cross-sectional and longitudinal studies using various 3D imaging techniques at 1.5 T and 3 T. MATERIALS AND METHODS In 21 subjects with osteoarthritis, magnetic resonance imaging (MRI) including four different sequences (sagittal 3D fat suppressed spoiled gradient-echo(More)
Pain at the ulnar aspect of the wrist is a diagnostic challenge for hand surgeons and radiologists due to the small and complex anatomical structures involved. In this article, imaging modalities including radiography, arthrography, ultrasound (US), computed tomography (CT), CT arthrography, magnetic resonance (MR) imaging, and MR arthrography are compared(More)
