Studies were conducted to verify the existence of IAA in wheat
seedlings and to determine the effect of (2-chloroethyl)-trimethyl-ammonium
chloride (CCC) on the IAA content of club wheat,
Triticum aestivum compactum, variety Omar. The shoots of CCC-treated
and untreated wheat plants were extracted with ethanol, the
plant extract purified, separated...
This study Is a rhetorical analysis of ten documents of Joseph
Smith, Jr's. early revelations spanning the period of 1829 to 1831
to determine the extent to which he used demagogic rhetoric in pursuit
of his goals. A definition of demagoguery is provided and is
applied in an analysis of...
Phenol-water and trichloroacetic acid extracts of Vibrio
anguillarum were both antigenic and immunogenic when injected
into coho salmon (Oncorhynchus kisutch). Cross-protection against
virulent Vibrio anguillarum was observed with whole-cell bacterins
and phenol-water extracts prepared from two serologically distinct
groups. Gel diffusion studies indicated that intact somatic antigens
were serotype specific....
Early studies on the biosynthesis of the quinoline quinone portion of
streptonigrin, 1, had suggested the intermediacy of novel aromatic amino
acids. In order to test this hypothesis, a series of compounds was synthesized
and tested for potential incorporation. [4-¹⁵N] 4-Aminoanthranilic acid,
4 5 a , [4-² H] 7-aminoquinaldinic acid,...
The population dynamics and reproductive strategies of the
stream snail Oxytrema silicula were examined in four coastal streams
in Oregon representing a small first order stream, a wider third
order stream and a fourth and sixth order stream. Samples were
taken in each type of stream bottom for each stream...
The sea offers a wide variety of potentially useful resources. Marine algae have been a rich source of structurally unique natural products showing diverse biological properties. The current need to develop new antifungal, antibiotic, anticancer and antiviral drugs has prompted intense research efforts into the discovery, isolation and structure determination...
Senator Al Gore Jr. was elected Vice-President of the United States
on November 3, 1992. During many of his public speeches, Gore utilized
a speaking style that differed radically from the style he used in other
political campaigns of his life. This style, which will be called the "rhetoric
of...
The physical, biological, chemical, and optical
processes of the ocean operate on a wide
variety of spatial and temporal scales, from
seconds to decades and from micrometers to
thousands of kilometers (Dickey et al., this
issue; Dickey, 1991). These processes drive
the accumulation and loss of living and nonliving
mass...
