Thesis research focused on: 1) Water and fertilizer gradients
within the plant root zone, and effects of chemical and physical
gradients on Trichoderma harzianum populations. 2) Regulation of root
growth physically with permeable fabric containers and chemically with
copper compounds. 3) Effects of copper coatings for fabric containers
on Glomus...
Smoking patterns were described and compared retrospectively for 5395 participants in the Lung Health Study at 12 and 24 months. 3592 participants were assigned to a special intervention (SI) group that received a counseling assisted smoking cessation intervention that included nicotine gum and 1803 participants were assigned to a usual...
The concept of ecosystem management requires that management prescriptions account for economic and environmental goals that are measured in non-commensurate units. This study examines the economic and environmental trade-offs associated with planting a riparian buffer in trees to reduce stream temperatures in the Mohawk watershed, Oregon. The detrimental effects of...
Design of commercial aircraft structure, composed of composite material, requires the
prediction of failure loads given large scale damage. In particular, a fuselage of
graphite/epoxy lamination was analyzed for damage tolerance given a standard large
crack that severed both skin and internal structure. Upon loading, a zone of damage is...

Radish anthocyanin extract has potential as a natural colorant because of
its pigment stability and attractive red hue. Presence of undesirable aroma
compounds could limit its applications in foods. The pungent principle of
radish, 4-methylthio-3-butenyl isothiocyanate (MTBI), is produced
enzymatically upon cell injury from its glucosinolate precursor, 4-methylthio-3-butenyl glucosinolate (MTBG),...
Determination of the source and fate of natural (higher plant lipids, marine
lipids, etc.) and anthropogenically (e.g., petroleum, coal emissions) derived
hydrocarbons and oxygenated compounds in the environment was accomplished
using gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS)
to characterize or identify molecular biomarkers to be utilized as tracers....
