Data on 10 patients with angina pectoris and fatal cardiac arrest during cardiac catheterization were analyzed to determine the circumstances of death and the severity and distribution of the coronary arterial narrowing. Nine patients died during attempted coronary angiography, and the remaining patient during right-sided cardiac catheterization. At least three of four major epicardial coronary...

Sampling, sample recovery, laboratory preparation and analysis and performing calculations all introduce errors into a final test result. Even without any mistakes, random errors will remain. The precision of a method -the size of likely random errors from all sources from sampling tech­ niques through data reduction -is determined by analyzing the differences between simultaneous measurements....

asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...

E-mails to government institutions as well as to large companies may contain a large proportion of queries that can be answered in a uniform way. We analysed and manually annotated 4,404 e-mails from citizens to the Swedish Social Insurance Agency, and compared two methods for detecting answerable e-mails: manually-created text patterns (rule-based) and machine learning-based methods. We found ...

Two samples of a manual 3 L calibrating syringe which displays an electronically calculated FEF25-75% were evaluated to determine its suitability as a flow calibrator were evaluated. Room air was discharged into a manual spirometer system known to be accurate. The calibrator-determined values correlated very closely with the spirometer values over an FEF25-75 % range of 0.4 to 9 L/sec. The diff...

INTRODUCTION/OBJECTIVE Pulmonary function tests (PFTs) are objective estimates of lung function, but are not reliably stored within the Veteran Health Affairs data systems as structured data. The aim of this study was to validate the natural language processing (NLP) tool we developed-which extracts spirometric values and responses to bronchodilator administration-against expert review, and to ...

an experiment was conducted to predict the true metabolizable energy (tmen) of compounded starter feeds of broiler chickens trough their chemical composition using precision-feeding method of sibbald in male boilers. in the first, eight compounded feed samples provided from eight feed plants and their chemical composition determined in laboratory. results of chemical composition showed that ave...
