Respiratory rates were measured, in situ, for the litter, the
soil, and the litter-soil subsystems of a Pseudotsuga menziesii forest
as a function of type of understory vegetation. The major objectives
were to demonstrate the utility of the litter layer as a distinct subsystem
of this forest ecosystem, to demonstrate...
The formation of solution and solid complexes with heavy metals
will partially determine their mobility and plant availability in soil
systems. Experiments were initiated to determine the effect of pH,
adsorbent and initial metal concentrations, and the presence of water
soluble ligands on the adsorption of Cd and Cu by...
Volatile hydrophobic compounds (HOCs) brought into soil and sediment
systems represent a serious threat to the environment. Dissolved
organic carbon (DOC) may exert an important influence over the total
aqueous solubility and mobility of organic pollutants through their
incorporation into micelles or the formation of soluble complexes.
To date, however,...
This research was undertaken to examine the symbolism
surrounding the sweatlodge and how it pertained to women in
Native American cultures. After an extensive literature
search I determined that there was little or no information
concerning the use of the sweatlodge by women. The goal of
the research was an...
In order to decide whether or not to develop biomass energy facilities and where to best locate them, developers and investors need accurate assessments of fuel supply. This includes information about the distribution and concentration of fuel throughout the assessment area, the quality of fuel (form, moisture content, contaminant content,...
The objective of this dissertation is to develop amorphous metal thin films (AMTFs) for two-terminal electrical device and nanolaminate applications. Two AMTFs, ZrCuAlNi and TiAl, are investigated in both two-terminal electrical device and nanolaminate applications. Material properties including composition, atomic order, surface morphology, surface potential, and electrical resistivity are explored....
Two studies concerning low molecular weight organic acids in soils were conducted. In the first study, anion exclusion chromatography was used to separate and identify 12 common organic acids, and the accuracy, precision and detection limits of the method were determined. The method was found to be sensitive and accurate...
Detection and treatment of bacterial kidney disease (BKD)
was investigated. Experiments were conducted to evaluate the
quantitative, fluorescent antibody technique (QFAT) that is used
to detect, identify, and quantify both typical and 'bar form'
Renibacterium salmoninarum cells. Smears of kidney tissue from
naturally and artificially infected salmonids, both with and...
