The adsorption kinetics exhibited by selected charge mutants of T4 lysozyme at
silanized silica surfaces were monitored with in situ ellipsometry. Mutant lysozymes were
produced by substitution of lysine (Lys) with glutamic acid (Glu). Each substitution
resulted in a decrease in the net charge of the protein by 2 units....
I studied sexual segregation in mule deer (Odocoileus
hemionus) and white-tailed deer (Q. virginianus) in
different environments and at different population
densities to test the hypothesis that sexual segregation
occurs in ungulates as the result of different
reproductive strategies; females select habitat and behave
in manners primarily designed to promote...
Alias periods and wavelengths for the M2, S2, N2, K1, O1, and P1 tidal constituents are calculated for TOPEX/POSEIDON. Alias wavelengths calculated in previous studies are shown to be in error, and a correct method is presented. With the exception of the K1 constituent, all of these tidal aliases for...
The shallow sections of most holes drilled during Ocean Drilling Program Leg 139 contain alkenones derived from prymnesiophyte algae. The alkenones indicate a paleotemperature of the photic zone in the upper ocean during primary carbon fixation of 7°-15°C, with an average of 10.7°C. Based on laboratory hydrous pyrolyses these alkenones...
There are a number of well known techniques for extracting parallelism from a given program. They range from hardware implementations, building restructuring compilers or reorganizing of programs so as to specify all the available parallelism. The success rate of any of the known techniques is rather poor over all types...
The connection between the fruit-set disorder Inflorescence Necrosis (IN) and high ammonium (NI14+) in affected tissues has led to an investigation of NH4+ assimilation enzymes (principally glutamine synthetase (GS) and glutamate synthase) in grape tissues. Previous work in this department has suggested that toxic levels of NH4+ build up in...
To remove small-scale variance and noise, time series of data are generally filtered using a moving window with a specified distribution of weights. Such filters unfortunately smooth sharp changes associated with larger scale structures. In this study, an adaptive low-pass filter is developed that not only effectively removes random small-scale...
A synthetic approach toward the two major fragments of cathedulin K-19,
euonyminol (4) and dimethyl cathate (69), was investigated. Synthesis of
dimethyl cathate was accomplished in 3 steps starting from 73. Efforts directed
towards the synthesis of euonyminol, a highly oxygenated dihydroagarofuran
sesquiterpene, was advanced to a stage in which...
The engineering design process and the advancement of future computer-aided-design systems need new design aids to be used during the conceptual design phase. This design phase is where information gathering and understanding of the problem are developed, analyzed and broken into small more manageable elements. These elements consist of customer...
The U.S. wood window and door industry has experienced much growth
for the past decade. However, to date, little information on factors that could
affect marketing strategies exists. This research represents an initial step for
providing this information.
A mail survey of U.S. wood window and door manufacturers was used...
The primary purpose of this study was t determine the
difference in "career progress" and satisfaction between
cooperative education/internship graduates and non-coop/
intern graduates of a small, private, non-engineering
college. A secondary purpose was to determine which other
independent variables (age; gender; SAT score; GPA; percent
of related work) contributed...
Current research on sport motivation has focused primarily on
goal perspective approaches in an attempt to understand behavior in
achievement situations (Ames, 1984; Nicholls, 1984). According to
Nicholls' (1984) theory, the achievement goal orientation an
individual develops may be influenced by both individual differences
and situational factors.
Relative to situational...
The topic of this thesis is to discuss an
investigation made for a fluid velocity measuring device.
The OSU thermal hydraulic testing facility is interested
in using a small probe to measure fluid velocities in the
annular region of a model nuclear reactor vessel. A
heater with a thermocouple embedded...
