The conventional speckle contrast measures only speckle severity, and is unable to characterize granularity and anisotropy in displayed images, which are easily picked up by human observers. Here, we propose a comprehensive method based on the power spectral density which allows the simultaneous measurement of three components of laser speckle-severity, granularity and anisotropy—as a superior ...

Control of microorganisms found on the skin of individuals is important to public health. The potential for the transmission of opportunistic pathogens to oneself or to others is significant, in the home, in institutional and commercial settings, as well as in healthcare settings. The risk of infection or acquisition of disease from the transmission of microorganisms can be correlated to specif...

A number of surveillance studies have been conducted looking for organisms with decreased susceptibility to antimicrobial agents in natural environments. There was no evidence of shifts in populations or development of resistance to the antimicrobial agents in any of these studies. Nor was there any evidence of a correlation of resistance between antimicrobial-tolerant strains and antibiotic re...

introduction one of the most important pre-processing steps in optical coherence tomography (oct) is reducing speckle noise, resulting from multiple scattering of tissues, which degrades the quality of oct images. materials and methods the present study focused on speckle noise reduction and edge detection techniques. statistical filters with different masks and noise variances were applied on ...

METHODS : A comparatives analysis of published articles was done to determine the relative efficacy and safety of ondansetron, droperidol, ,metoclopramide, dexamethasone,and Intravenous crystalloid fluid For the prevention of postoperative nausea and vomiting. I performed a literature search of English references using both the MEDLINE database and a manual search. Double-blinded, randomized, c...
