We sought to improve net ecosystem exchange (NEE) estimates for a tall, dense, mature Douglas-Fir forest in the Oregon Coast range characterized by weak flows, systematic wind directional shear, and limited turbulent mixing throughout the diurnal period. We used eddy covariance (EC) observations at two levels and concurrent biological measurements...
Environmental factors such as temperature, air, and water can have a profound
effect on the durability of asphalt concrete mixtures. In mild climates where good
quality aggregates and asphalt cement are available, the major contribution to
deterioration may be due to traffic loading and the resultant distress is manifested
in...
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...
The work presented in this dissertation highlights the various techniques available to characterize the increasingly complex surfaces of engineered biomaterials. The methods used range from the simple measurement of a contact angle with a smartphone to a complex synchrotron technique like near edge x-ray absorption fine structure (NEXAFS) spectroscopy to...
Adenosine 3', 5' -cyclic monophosphate (cyclic AMP, cAMP) and guanosine 3', 5' -cyclic monophosphate (cyclic GMP, cGMP) were quantitated in the central nervous system (CNS) of the insect Manduca sexta by competitive protein binding techniques. The M. sexta CNS was found to contain a strikingly high level of cGMP, about...
The peripheral-type benzodiazepine receptor (PTBR) of trout brain was
pharmacologically characterized and pyrethroid interaction with this site
investigated. High-affinity binding sites for [³H]PK 11195 were detected in brain
membranes of rainbow trout; these shared some of the characteristics of the
PTBR of rodent brain (i.e., high affinity for PK 11195...
