OBJECTIVE To identify the level of consensus among a group of Canadian emergency department (ED) experts on the importance of a set of indicators to document ED overcrowding. METHODS A 2-round Delphi survey was conducted from February 2005 to April 2005, with a multidisciplinary group of 38 Canadian experts in various aspects of ED operations who rated the relevance of 36 measures and ranked ...

the present study is aimed at the overall improvement in the efficacy, reduced toxicity and enhancement of therapeutic index of cisplatin. nanocapsules of cisplatin containing ethylcellulose have been prepared using solvent evaporation technique under ambient conditions. the prepared nanocapsules were used for controlled drug release of anticancer agents with gold and iron oxide nanoparticles. ...

Digital subtraction radiography requires close matching of the contrast in the films to be subtracted. A digital melhod is presented permitting the retrospective correction of film contrast differences. The method is nonparanietric and derives the required gray level transformation directly from the histograms associated with the radiographs. This transform is shown to be unique and monotonic. ...

PURPOSE This study examined the use of the Tucker linear equating method in producing an individual student's score in 3 groups with bridging stations over 3 consecutive days of the clinical performance examination (CPX) and compared the differences in scoring patterns by bridging number. METHODS Data were drawn from 88 examinees from 3 different CPX groups-DAY1, DAY2, and DAY3-each of which ...

A novel approach to quantifying postural stability in single leg stance is assessment of time-to-boundary (TTB) of center of pressure (COP) excursions. TTB measures estimate the time required for the COP to reach the boundary of the base of support if it were to continue on its instantaneous trajectory and velocity, thus quantifying the spatiotemporal characteristics of postural control. Our pu...

In Table 4, the values for mean and standard deviation are incorrect. Please see the corrected Table 4 here.

Hungry, unrestrained rats (N = 7) were rewarded for pressing a response beam in excess of 11 different force requirements. Changes in peak force production as a function of peak force requirement were examined by analyses of the first four moments of distributions of peak response forces: constant error, the within-subject standard deviation, skewness, and kurtosis. Results were similar to thos...

A new approach for predicting a wide range of physical and thermodynamic properties is proposed. It involves calculation of the molecular descriptors of a target compound of unknown properties, followed by regression of this vector of molecular descriptors versus a database of compounds with known descriptors and measured properties. The regression model, obtained for the descriptors of a targe...
