In vitro studies of Mobam (4-benzo(b)thienyl N-methylcarbamate) metabolism have demonstrated that at least three ether soluble metabolites are formed in a microsomal system fortified with reduced triphosphopyridine nucleotide (NADPH). One of the metabolites was identical to 4HBT (4-hydroxy benzothiophene), the phenol of Mobam. The other two metabolites did not possess...

The purpose of this.investigation was to determine how enzymes and oxygen influence the role ascorbic acid has on pigment degradation and browning during storage for strawberry juice and concentrate.
The ascorbic and dehydroascorbic acid content of blanched and unblanched, nitrogen-treated and air-exposed samples of strawberry juice and concentrate was measured...
A high performance liquid chromatography (HPLC)
procedure using a LiChrosorb-NH₂ column and a eluant
buffer of 75:25 (v/v) of acetonitrile:0.05 M KH₂P0₄, pH
5.95, was developed for the successful separation and
determination of ascorbic and erythorbic acids in selected
food samples.
Application of the method, which is sensitive, rapid
and...
Commercially bottled, vitamin C-fortified, cranberry
juice cocktail and cranberry-apple (cranapple) juice
drinks were stored at 5°C under simulated home-use
conditions. Ascorbic acid (AA) and dehydroascorbic acid
(DHA) levels were evaluated over a period of seven days by
high performance liquid chromatography (HPLC). Total
vitamin C content was also determined by...
Soil erosion by mass wasting is the major problem on forest
lands of the Pacific Northwest, The clay fractions of soils from a
large number of sites in Oregon's Western Cascades were characterized
in order to determine the relationships of various clay materials to
mass movements. Each site was either...
In order to investigate potential climate impacts on landscape-scale ecosystem processes, I implemented a dynamic general vegetation model (DGVM) over a large domain in northern California and western Nevada on a rectangular grid of ca. 800-meter spatial resolution. I used 100 years of observed, monthly climate and nine future climate...
