Instrumental and radiochemical neutron activation analyses supported by electron microprobe mineral analyses (Paul Warren, University of New Mexico) and petrographic observations are presented for approximately forty individual clasts separated from the Kapoeta howardite. These clasts are classified into eucritic, cumulate-like, mafic (plagioclase ± olivine-bearing pyroxenites), pyroxenite, polymict and/or metal-rich and...
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...
The preparation of holocellulose accurately and rapidly is very
important to study the nature and relationships of the carbohydrate
components and the substituent groups, acetyl, carboxyl, and methoxyl.
In as much as bromine was thought to be less destructive to
wood than chlorine, it was decided to attempt to isolate...
A heat stable derivative of bovine serum albumin containing
300 residues of glycine added to 30 sites on the surface of the protein
has been prepared. This derivative may be heated to 100° C for
prolonged periods of time without aggregation. By comparison,
native BSA aggregates at 62° C under...
This thesis is concerned with the development and use of routine
analysis techniques based on chemiluminescence (CL) detection for: 1)
ethanol in gin down to the 0.3% (v/v) level; 2) the antioxidants propyl
gallate and BHA in lard to levels as low as 0.3 and 0.2 mg/L, respectively; 3) pyrogallol...
Verrucarol is the sesquiterpene portion of a number of macrocyclic di- and triesters of potential medicinal importance. In this study, a novel approach to the synthesis of this fungal metabolite is presented. An A-B-C route was investigated in which C-3 and C-4 of the C-ring were emplaced using a [2+2]...
