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 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...
My thesis, entitled "Fantastic Histories: How Malory's Morte Darthur
Influenced Tolkien's The Silmarillion," argues that J.R.R. Tolkien's Silmarillion
shares distinct similarities in style and content with Sir Thomas Malory's Morte
Darthur, primarily in the lack of detail in the descriptions of characters and events, as
each attempts to create a...
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...
Small commercial and non-commercial animal enterprises (SCAEs) raise a few
beef cows, horses, pigs, sheep, poultry, and other animals on a few acres. These
enterprises are often located in suburban areas of watersheds and show potential for
degrading water quality through to increased bacterial, nitrogen, and phosphorus
concentrations. SCAEs implement...
For management purposes, it would be useful to be able to predict streamflow response to forest practices in small, unmonitored basins. The primary objective of this study is to investigate the influence of early successional vegetation on summer streamflow levels. The long-term data records from watershed 1 at the H.J....
American meteorology was synonymous with subjective weather forecasting in the early twentieth century. Controlled by the Weather Bureau and with no academic programs of its own, the few hundred extant meteorologists had no standing in the scientific community. Until the American Meteorological Society was founded in 1919, meteorologists had no...
The inhibition of the enolase enzyme system by fluoride has
been established for many years in in vitro experiments; however,
this inhibitory action has never been demonstrated in an intact mammal.
The present work was designed to examine the effect of fluoride
administered by intravenous infusion in rats, under the...
