Studies were undertaken to determine the extent and rate of
binding of Hg-203 labeled phenylmercuric acetate and mercuric ace
tate in rat kidney and liver slices and their subcellular fractions
after 37°C incubation of the slices in Krebs-Ringer -phosphate solutions
containing the mercurials at 10⁻⁴ molar. A fast and parallel...
An oscillating plasma glow discharge detector for gas
chromatography is used to obtain fingerprint information
about an analyte by combining both the average cell
current and oscillation frequency signals. Five homologs
each of the n-alkanes, 1-alkenes, 1-alkynes, 2-ketones and
aldehydes are studied. Although triplicate determinations
had some scatter due to...
An atmospheric pressure argon glow discharge is shown
to detect trace levels of carbohydrates in aqueous flowing
systems, using either of two glow discharge solution
interface configurations. The first configuration consists
of an oscillating glow discharge sustained between a flowing
aqueous cathode and platinum anode. Picomole and micromolar
mass and...
The use of an adjacency matrix to determine distant (not maximal or
minimal) subgroup and supergroup relationships between crystallographic spacegroup
types is described. Full lists of space-group types that are supergroups and
subgroups for every space-group type were compiled. A list of the space-group
types connected to each space-group type...
Sulfide is an important species to measure in environmental water samples. The
spectrophotometric detection method for reduced sulfur species (sulfide) based on
generation of methylene blue was adapted to work in an apparatus utilizing microfluidic
PDMS mixing and observation cells with flow channels in the 100 μm range. The
benefits...
