New bioactive natural products from marine algae and cyanobacteria

Creator:: Sabry, Omar Mohamed
Abstract:: This thesis is an account of investigation on the natural products deriving from various marine algae and has resulted in the discovery of eleven novel bioactive metabolites. Isolation and characterization of these new molecules were carried out using different chromatographic techniques and by analyses of different spectroscopic data, respectively. Using...

Aspects of comparative neuromuscular physiology and pharmacology of black bass (Micropterus salmoides) as evidenced by the action of diisopropylfluorophosphate

Creator:: Schneider, Phillip William
Abstract:: Neuromuscular physiology has been extensively investigated in several groups of vertebrates excluding fish. To understand the nature of neuromuscular transmission in this group, the response of the pectoral fin abductor muscle of black bass (Micropterus salmoides) to nerve stimulation under the influence of an anticho1inesterase agent was studied. Diisopropylfluorophosphate (DFP),...

Development, performance evaluation and application of a physical model of the Kenyan-Tanzanian coastal region

Creator:: Mayorga Adame, Claudia Gabriela
Abstract:: A Regional Ocean Modeling System (ROMS) application for the coastal region of Kenya and Tanzania (0-10° S, 38.7-46.98° E) was developed with the aim of better resolving the circulation patterns in the coastal region that is poorly represented in global models. The model has a horizontal resolution of 4 km,...

The infection and colonization of Douglas-fir needles by the Swiss needle cast pathogen, Phaeocryptopus gaeumannii (Rhode) Petrak

Creator:: Capitano, Bryan R.
Abstract:: Phaeocryptopus gaeumannii is a pathogenic fungus on Douglas-fir needles which has become a serious threat to timber production in the last decade along the Oregon coast This research was undertaken to describe the general biology and pathology of F. gaeumannii on Douglas-fir needles and how environmental variables affect fungal development....

Status, distribution and seasonal variation of filbert aphid resistance to selected insecticides in the Willamette Valley, Oregon

Creator:: Katundu, Juma
Abstract:: Levels of resistance to six selected insecticides of eleven field populations of the filbert aphid Mvzocallis coryli (Goetze) were determined by using the leaf-dip residue technique. Test insecticides included compounds widely used in commercial filbert orchards, namely, carbaryl, diazinon, endosulfan, phosalone, fenvalerate and oxydemetonmethyl. Aphid samples were collected within a...

Factors influencing the herbicidal activity and persistence of isomers of 1, 1-dimethyl-diisopropyl-indanyl ethyl ketone in soil

Creator:: Donaldson, Dean Robert
Abstract:: The purpose of this study was to evaluate the activity of Sindone (isomers of 1, 1-dimethyl-diisopropyl-indanyl ethyl ketone) under field conditions and to gain information regarding the rate of detoxification of Sindone in soil. A series of trials were established in sugar beet fields in California, Oregon, and Washington. Sindone...
