Early studies on the biosynthesis of Sarubicin A, 1, had suggested the
intermediacy of the novel aromatic amino acid 6-hydroxyanthranilic acid,
17. To investigate the biosynthetic steps beyond 17, [¹³C-¹⁵N carboxamide]
6-hydroxyanthranilamide, 27a, was synthesized, and fed to fermentations
of Streptomyces helicus. Incorporation of 27a into 1 provided suggestive
evidence...
This thesis deals with a modification to an existing mathematical
ppogramming algorithm called Beale's method. This method is
designed to solve only quadratic or linear programming problems.
The modification proposed aims to solve some of the problems this
method encounters and to shorten the time required for solution by
examining...
Zebrafish are a powerful model organism to study disease. Like other animal models, Danio rerio colonies are
at risk of pathogenic infection. Microsporidia, a group of intracellular fungus-like parasites, are one potential
threat. Microsporidian spores germinate and spread causing pathological changes in the central nervous system,
skeletal muscle, and other...

Abstract
Zebrafish are a powerful model
Zebrafish are a powerful model organism to study disease. Like other animal models, Danio rerio colonies are at risk of pathogenic infection. Microsporidia, a group of intracellular fungus-like parasites, are one potential threat. Microsporidian spores germinate and spread causing pathological changes in the central nervous system, skeletal muscle, and other...
The relationship between nitrogen (N) availability and the growth of macroalgae in a seasonal upwelling region (Yaquina Head, Oregon, USA) was investigated. Water column nutrient concentrations were relatively high and stable during the winter, decreased in early spring, and were highly variable in the summer and early fall. Periods of...

Good management practices are essential if optimum fertilizer responses are to be realized. These practices include adequate irrigation, use of recommended varieties, selection of adapted soils, weed control, disease and insect control, good seedbed preparation, proper seeding methods, and timely harvest. Follow recommended soil sampling and testing procedures to estimate...
