Iodine-129 is a key risk driver at sites where nuclear materials have been fabricated or processed, and it is a predominant isotope of concern in long-term waste storage strategies. I-129 exists primarily as iodate in the subsurface at the Hanford Site in south-central Washington State. Between 15 and 40% of...
Six organoclay complexes have been studied in terms of their
selective adsorption from binary solutions of methanol and toluene.
Analyses are based on differential refractometry methods. The
isotherms were of the usual "S" type. The crossover points reveal
trends in the organophilic nature of the interlaminar surfaces in
these clay...
Improvements in instrumentation for fluorometric kinetic
measurements and the application of a new intensified diode array (IDA)
rapid scanning system to low level transient fluorescence measurements
are reported. This instrumentation is applied to a new fluorometric
kinetic method for thiamine (TM).
Modifications to the existing fluorometric reation rate instrument
include...
Isomerically pure cis,cis,trans-1-pheny1-1,3,5-
heptatriene was prepared and cyclized. Ring closure
was followed by a 1,5 hydrogen shift, and the only product
observed was 1-phenyl -6-methyl -1,3-cyclohexadiene.
Rough first order rate constants for thermolysis and
the hydrogen shift were determined. Kinetic estimates
indicate that the report of disallowed product in a...
Moral distress is the experience of knowing the right action to take but being unable to take it. It is especially prevalent in the healthcare profession, where professionals’ actions are limited by the wishes of patients and their families, hierarchies, and organizational failings. Since it is accepted that healthcare professionals...
Neurofilament proteins are intermediate filaments found in the neuronal cytoskeleton. Phosphorylation of these proteins is considered important for the assembly and stability of the filaments. Accurate molecular weights have been difficult to measure, largely because the high degree of phosphorylation results in M[subscript r]'S that are significantly greater than dictated...
In this report, three studies are presented that utilize computations to predict transformations, identities, and properties of environmental organic molecules. Each study shows how computations can lead to models of chemical behavior. The importance of this research is rooted in the need for understanding how human behavior and health intersect...
