The strongest isotope effect is observed for the 6a vibrational mode, which differs by about 6 cm for the two isotopomers. MATI spectra have also been recorded for the Van der Wals complex chlorobenzene · Ar . Upper limits for the dissociation energies of the complex in its cationic state, ...
The concept of probabilistic parameter threshold analysis has recently been introduced as a way of probabilistic sensitivity analysis for decision-making under uncertainty, in particular, for health economic evaluations which compare two or more alternat
We investigate the biological effects of radiation using adult Drosophila melanogaster as a model organism, focusing on gene expression and lifespan analysis to determine the effect of different radiation doses. Our results support a threshold effect in response to radiation: no effect on lifespan an...
1 is the absence of a first-pass effect in the liver. The parameter AE in Eq. (1) considers absorption from the GIT into the portal vein and does not explicitly account for the potential reduction in systemic blood concentrations (and whole-body concentrations) that may occur if there is ...
