In vivo absorption spectroscopy for absolute measurement
In in vivo spectroscopy, there are differences between individual subjects in parameters such as tissue scattering and sample concentration. We propose a method that can provide the absolute value of a particular substance concentration, independent of these individual differences. Thus, it is not necessary to use the typical statistical calibration curve, which assumes an average level of scat...
متن کاملAbsolute humidity and pandemic versus epidemic influenza.
Experimental and epidemiologic evidence indicates that variations of absolute humidity account for the onset and seasonal cycle of epidemic influenza in temperate regions. A role for absolute humidity in the transmission of pandemic influenza, such as 2009 A/H1N1, has yet to be demonstrated and, indeed, outbreaks of pandemic influenza during more humid spring, summer, and autumn months might ap...
متن کاملAnalysis of X-ray absorption fine structure using absolute X-ray mass attenuation coefficients: Application to molybdenum
XAFS structures are solved routinely and hundreds of publications appear per annum. Limitations in theoretical predictions and XAFS analytical frameworks lead to significant uncertainty in results. This impairs structural predictions and prevents ab initio determination. The highest accuracy experimental data have been obtained using the XERT and the most popular technique to analyse the struct...
متن کاملThe influence of absolute humidity on shear bond adhesion.
OBJECTIVES The purpose of this study was to investigate the relationship between dentine shear bond strength, using data from experiments performed according to a standard protocol, and the absolute humidity for a new, fourth generation dentine adhesive system. METHODS Results of seven recently performed adhesion experiments using the same protocol and product were analysed. Groups of 10 huma...
متن کاملAbsolute humidity modulates influenza survival, transmission, and seasonality.
Influenza A incidence peaks during winter in temperate regions. The basis for this pronounced seasonality is not understood, nor is it well documented how influenza A transmission principally occurs. Previous studies indicate that relative humidity (RH) affects both influenza virus transmission (IVT) and influenza virus survival (IVS). Here, we reanalyze these data to explore the effects of abs...
