A waveform-preserving, variable time-delay system capable of
several milliseconds delay is described in this thesis. These considerably
long delays are achieved by judicious use of the relatively
low sonic velocity of gases. Initial system design criteria specified
a time delay of ten milliseconds and a signal bandwidth of 0-10 KC....
Paralytic shellfish poisoning (PSP) is an acute toxic illness in humans resulting from ingestion of shellfish contaminated with a suite of neurotoxins (saxitoxins) produced by marine dinoflagellates, most commonly in the genus Alexandrium. Poisoning also has been sporadically suspected and, less often, documented in marine wildlife, often in association with...
This is a student report which studies the effects of wave action on intertidal zonation at Yaquina Head. It includes hand-drawn diagrams of quadrants sampled at the location.
Halo bacterial blight caused by Pseudomonas syringae pv. phaseolicola (Psp) is a serious seed-borne disease of common bean (Phaseolus vulgaris L.). The disease can be controlled by major resistance (R) genes effective against specific races of the pathogen. Our objective was to characterize the R gene(s) conferring resistance to Psp...
