چکیده
In the last ten years, the use of gamma-ray spectrometry for geological mapping and mineral exploration has shown considerable growth. With this growth, standardized procedures have been developed for the calibration and processing of the airborne measurements so that they will be independent of survey parameters. This paper describes some of the new developments to convert airborne data to ground concentrations of potassium, uranium and thorium. There are now accepted procedures for removing atmospheric background variations using upward-looking detectors and through spectral analysis. Recently, more reliable measurements of the ground concentration of potassium, uranium and thorium have been achieved through analysis of the 256 channel spectrum.

The financial and environmental costs of reusable and single-use plastic anaesthetic drug trays.
We modelled the financial and environmental costs of two commonly used anaesthetic plastic drug trays. We proposed that, compared with single-use trays, reusable trays are less expensive, consume less water and produce less carbon dioxide, and that routinely adding cotton and paper increases financial and environmental costs. We used life cycle assessment to model the financial and environmenta...

متن کاملTesting the Measurement Equivalence of Interactive Voice Response (ivr) and Paper Versions of the Eq-5d
OBJECTIVE: Electronic data capture technologies, such as interactive voice response (IVR) systems, are emerging as important alternatives for collecting patient-reported outcomes data. The objective of this study was to assess the measurement equivalence of an IVR version of the EQ-5D with the original paper version. METHODS: This study utilized a crossover design with subjects randomly assigne...
