BACKGROUND A valid and practical measure of comorbid illness burden in dialysis populations is greatly needed to enable unbiased comparisons of clinical outcomes. We compare the discriminatory accuracy of 1 year mortality predictions derived from four comorbidity instruments in a large representative US dialysis population. METHODS Comorbidity information was collected using the Index of Coex...

Early diagnosis of infective endocarditis (IE) is based on the yielding of blood cultures and echocardiographic findings. However, they have limitations and sometimes the diagnosis is inconclusive, particularly in patients with prosthetic valves (PVs) and implantable cardiac electronic devices (ICEDs). The primary aim of this study was to evaluate the diagnostic accuracy of 18F-FDG PET/CT in pa...

Icings on moving machinery, such as wind turbines and aircraft wings, degrade their performance safety. Ultrasonic vibration is considered one of the deicing methods. In this research, simulations experiments are carried out to explore effect ultrasonic adhesive characteristic ice aluminum alloy plates. Harmonic response analyses conducted analyze changing distributions shear stresses at interf...

During the last two years, progress has been made in the field of de-icing technology as a result of the development of a new very simple technique in which an overhead cable is de-iced by twisting. With this new mechanical method, the iced cable is rotated in the elastic domain of deformation at one end, while fixed at the other extremity. The ice bond is broken at the ice/cable interface by t...

OBJECTIVE During partial nephrectomy, renal hypothermia has been shown to decrease ischemia induced renal damage which occurs from renal hilar clamping. In this study we investigate the infusion rate required to safely cool the entire renal unit in a porcine model using retrograde irrigation of iced saline via dual-lumen ureteral catheter. MATERIALS AND METHODS Renal cortical, renal medullary...

In view of the shortcomings of current image detection methods for icing thickness on power transmission lines, an image measuring method for icing thickness based on remote online monitoring was proposed. In this method, a Canny operator is used to get the image edge, in addition, a Hough transform and least squares are combined to solve the problems of traditional Hough transform in the param...

Nowadays, a large quantity of seafood is still moved to market essentially unpackaged. Whole or gutted fish are iced in fish holds, stored upon landing and then re-iced in bulk containers to be hauled to local fish markets. At the market, whole, dressed or filleted fish are displayed and offered for sale (still unpackaged) on a bed of ice. A switch from wooden to waxed or plastic-coated corruga...

In this study we present the evaluation of a model for the interactive sonification of footsteps. The sonification is achieved by means of specially designed sensored-shoes which control the expressive parameters of novel sound synthesis models capable of reproducing continuous auditory feedback for walking. In a previous study, sounds corresponding to different grounds were associated to diffe...

in iran, there are about 10% losses in black tea processing, which is called tea dust. tea dust is produced through black tea screening, during the last stage of production. in this research, regarding the increasing demand for new beverages, the production of iced tea beverage using black tea dust was investigated. process of iced tea involved tea solid extraction and then mixing with edible a...
