Victoria blight of oats is caused by the fungus Cochhobolus victoriae. This fungus is pathogenic due to its ability to produce the host-selective toxin victorin. Previously, a 100-kD protein that binds victorin in vivo only in susceptible genotypes was identified as
the P protein of the glycine decarboxylase complex (GDC)....

Best available copy. In 1984, longstanding concerns about pollution in Yaquina Bay impelled the U.S. Food and Drug Administration to make a comprehensive sanitary survey of the Yaquina River, with particular emphasis on areas where oysters were grown. The report states that the oyster plots endured "sporadic poor water quality,"...
Modern engineered systems are increasingly integrated into society, decentralized, and interconnected. However, scale and complexity create unique challenges in system design, such as emergent behavior and unintended consequences. This work investigates the structural characteristics of robustness in complex engineered systems by identifying patterns of under-recognized vulnerabilities at various levels of...
Effects of lactobacilli in enteric coated capsules
were studied in piglets (Chapter I). Lactobacillus
acidophilus and Lactobacillus bulgaricus isolated from a
commercial product were formulated in capsules, enteric
coated, and then given to both Escherichia coli-challenged
and unchallenged baby pigs. Decreased
incidence and severity of diarrhea, and decreased weight
deceleration...
Algae have shown great potential as a source for renewable fuels. However, current production schemes have not been able to prove a sustainable energy return on investment due in part to the high costs of nutrient addition and the energy required for drying the biomass. Integrated algae-dairy production systems have...
The work described herein details the synthesis and application of
biphenyls that probe the effects of hydrogen, Cl / Br, and methyl substituents
on the aryl ring of the terminal acetylenic carbon. From this work, we
successfully developed the rapid synthesis of phenyl acetylenes in 3-4 steps
from inexpensive commercially...
The paper argues that efficiency in regulating fishery resources is inversely proportional to number of management levels involved, distance of each level from the industry intended to be regulated, while gear and species play an important role. Among possible examples buy back programs are proposed, but other examples can be...
A study on the cellular differentiation of the gill structure in
juvenile coho salmon (O. kisutch) with emphasis on the excretion of
monovalent ions was performed upon animals maintained under both
seawater and freshwater environments.
1. The excretion rate of sodium-24 was observed to be higher
for animals adapted to...
A cost reduction analysis is performed by coordinating
the exchange of LANDSAT (formerly ERTS) data between a CDC
3300 and a PDP8/L minicomputer. The LANDSAT data is displayed
on a 4002 Tektronix terminal by means of a grayscale output.
Large amounts of data and number manipulation are processed
in the...
