Each chapter in this expository paper considers a mathematical model of an aspect of animal behavior, and how it affects the patterns of movement across and within a landscape. These models are all directly or indirectly related to questions in either Behavioral Ecology or Landscape Ecology, or both. I first...
A facility developed using the OSU TRIGA pulsing capability and high speed motion photography has been used successfully for more than a decade to produce dynamic neutron radiographs of solid propellant combustion, two phase flow, and liquid streamflow. The existing imaging components have undergone little modification since the experiment's inception...
The topic of summability methods has been studied by many
although the name of G. H. Hardy and his classical work "Divergent
Series" is best known. Almost all of the early work was done using
single sequences or series. In the past 30 years research has been
done extending some...
This study was conducted to examine the coefficient of drag resistance (µ) between a log and bare forest soil during partial
suspension yarding. Drag resistance in this study was defined as the resistance due to friction between the soil and the log plus the resistance due to the plowing action...
This paper explores the language theories of Gary Snyder, an important modern environmental author whose early work was associated with the Beat movement of the early 1950's. I am particularly interested in Snyder's thoughts on how language relates to nature. I focus primarily on Snyder's prose in attempts to understand...
An enabling technology for long duration, deep space missions is the availability of a high power, long-lived power supply. The goal of this work is the design of a self-regulating deep space nuclear reactor. The design objectives are to produce 250 kWth for a 25-year period using the presence of...
A systematic study of the elution of magnesium and calcium from
Dowex 50 X 8 resin using α-hydroxyisobutyric acid (α-HIBA) at
various pH values and concentrations, indicated that the difference in
the equilibrium distribution coefficients of these two elements was
large enough for a good separation. This fact was applied...
Recombinant human macrophage colony stimulating factor beta (rhm-CSFβ) is a glycoprotein that stimulates the proliferation, differentiation and survival of cells belonging to the monocyte-macrophage lineage. It contains nine inter-subunit and intra-subunit disulfide bonds and represents an excellent model system for studying disulfide bond formation during protein folding because the assembly...
E. coli thioredoxin (TRX) was modified by the episulfonium ion derived from S-(2-chloroethyl)glutathione (CEG) or S-(2-chloroethyl)cysteine (CEC). The alkylation site was located at Cys-32, which was confirmed by tandem mass spectrometry. Two forms of native TRX, Oxi- and Red-TRX, and two modified TRXs, GS- and Cys-TRX, were examined by hydrogen/deuterium...
The reactions of EGTA, [ethylene bis (oxyethylenenitrilo)]
tetraacetic acid, with 51 metal ions have been studied spectrophotometrically in aqueous solutions.
The absorption spectra of the
chelates formed were measured with a recording spectrophotometer
between 200 and 700 mμ. The pH of each solution was varied and a
spectrum was scanned...
An analytical tool to assist municipal planners in evaluating
alternative planning strategies is proposed. Schlager's Land Use
Plan Design Model provides the linear formulation of the problem,
Goal Programming is used to create alternatives, and Brown and Kirby's
Measures of Urban Performance serve to evaluate the alternatives.
Resource Planning and...
The Clarno Formation is a series of volcanic, volcaniclastic, and related intrusive rocks located in central Oregon. It is the westernmost extent of a broader Eocene magmatic belt that covers much the western United States. The magmatic belt stretches eastward from Oregon to western South Dakota, and from the Canadian...
In the late 1850s, few young Jews, recently arrived in the United States from Poland, chose to live in Florida. Fortunately, one who did, Max White, wrote down his memoirs of those years, leaving us a remarkable, very personal account of life on the Florida frontier as well as a...
Two approaches to the tricyclic core of the furanoeremophilane sesquiterpenoids are described. The first approach entails a projected Diels-Alder/retro Diels-Alder reaction of an acetylenic oxazole 64. Construction of the pivotal aldehyde 67 commenced from ketone 68. The acetyenic moiety was then introduced via a Felkin-Ahn addition of lithiopropyne to aldehyde...
