The result is normally a number above zero and less than several hundred (or several thousand). Obviously, lower VHR values represent a classification representing a solvent more safe to use. VHR is useless as absolute information.232Like the IRCHS value, the VHR value has meaning only when ...
I’ll close by acknowledging that there are costs to my approach. If Italy is not given a bailout, the country may have a “disorderly default,” meaning the government simply stops honoring its commitments to pay bondholders. That is bad for individual bondholders, but it also could hurt ...
Noisy data typically refers to corrupted, distorted, or low signal-to-noise ratio observations, which are common in natural hazard analysis, especially in seismology-related investigations. Seismic data are vulnerable to contamination by different types of noise. This noise is defined as all unnecessar...
Packing Group I – Any material that spontaneously ignites when mixed with cellulose in a 1:1 ratio or any material that exhibits a mean pressure rise time less than the pressure rise time of a 1:1 perchloric acid (50%):cellulose mixture Packing Group II – Material that exhibits a mean ...
To make our analysis comparable with the findings in the literature, we use as the reference point the ratio between the deductible amount and the corrected mean actual spending. In our estimations the ratio represents less than one third of the mean spending of the sample (0.30 = USD ...
Percentage living without adequate sanitation or water supply, percentage of urban areas classified as slum, percentage undernourished, dependency ratio (those aged under 15 and over 65 as percentage of working age population), percentage living on less than USD 1.25 per day, gloss domes...
It performs the likelihood-ratio test between the full model and the model without covariates interacted with time, that is, without specifying the tvc() option. By default, the Wald test of coefficients on time-varying covariates equal to zero is reported when tvc(varlist ) is specified. ...
The term hazard ratio is often used interchangeably with the term relative risk ratio to describe results in clinical trials. This is not strictly correct as there are subtle and important differences. It is useful to understand the meaning of the term and also be able to identify when it is...

The Commission [11] applied a ratio of 193, which leads to a correction factor of 1.81 = 349/193. The alveolar clearance half time according to Gregoratto et al. [32] is 255 days. MAK [11] applied 400 days. This leads to a second correction factor of 1.57 = 400/255. ...
