A continental shelf bottom boundary layer model : the effects of waves, currents, and a movable bed
… current velocity, and suspended sediment concentration profiles predicted by the simultaneous solution of the conservation equations require the physical bottom roughness and a sediment reference concentrati on to be specified as boundary conditions. The physical bottom roughness …

EXPLORING RISK ASSESSMENT METHODS TO EXAMINE NEUROLOGICAL RISK DUE TO AIR TOXIC EXPOSURE IN MINNESOTA
… calculating the ratio of the inhalation exposure concentration (EC) to the reference concentration (RfC). In addition, the EPA additively models the neurological risks of different pollutants (HQ) to estimate an aggregate neurological risk score (hazard index (HI)) for each census tract. We …

Intraurban Variability of Ambient Particulate Matter
… these metrics for each site with respect to a reference concentration time series may better reveal the variability. In the absence of a representative background site, the network itself can be utilized to generate baseline and site-specific excess concentration time series to …

Wave-induced sediment transport on an estuarine intertidal flat
… sensors could be used to separately measure the concentration of suspended silts and suspended sands. Comparison of pressure and velocity data revealed an inconsistency in some wave data from the Wiroa flat and in Green and MacDonald's (2001) data from the Okura estuary: wave amplitudes estimated …

Nearshore sediment dynamics in a mixed sand/mud environment
… the ratios of estimated to predicted near bed reference concentration (ζ) and either the median grain size (d₅₀) or the ratio of percent sand to mud of the seabed. However, a good correlation was found between ζ and the normalised in-situ shear strength (𝑥) of the seabed (adjusted R² = 0.99), …

Novel Lanthanide Containing Polymers for Nucleic Acid Delivery and Monitoring of Polyplex Dynamics
… chains. This was supported by using an internal reference method to quantify free polymer amount from known internal reference concentration. We observed an increase in the amount of free polymer with N/P ratio for all three systems and both the methods showed comparable results.

Applications and developments of chemometric methods for process analytical chemistry
… within process analysis. NIR is used as a reference method for the GMS to aid interpretation of the spectra, and relate it to the process.Various processes have been investigated to determine the effectiveness of NIR and GMS to monitor them. A drying process has been monitored which has a …
