Forest management is typically associated with a high degree of uncertainty, since it relies on predictions of natural growth processes over long periods of time. A number of methods exist for mitigating the risk associated with this uncertainty, but few have the ability to explicitly minimize risk. This study will...
Exposure to ultraviolet (UV) radiation is a primary cause of melanoma and non-melanoma skin cancer and thus represents a critical public health concern. Skin cancer risk behavior research lacks an instrument designed to assess health beliefs about UV exposure that may increase skin cancer risk by increasing risky UV exposure...
Exotic ponderosa pine (Pinus ponderosa Doug. ex Lawson) plantations are being planted within the natural distribution area of cordilleran cypress (Austrocedrus chilensis (D.Don) Pic. Ser. et Bizzarri) in Patagonia, Argentina. The productivity of these exotic plantations is much greater than that of native forests, suggesting greater water use. Before these...
The goals of this research were to a) characterize the protein-function relationships of skeletal muscle single fibers from the mouse hindlimb b) examine mouse-strain related differences in myosin heavy chain composition (MHC) and single fiber contractile function, and c) quantify changes in fiber size and contractile function in response to...
Vertical transports of plankton, momentum, heat, and turbulence are modeled. A novel integration of high resolution turbulence and biophysical modeling is used to show the influence of a Kelvin-Helmholtz instability on the vertical migration of simple gyrotactic organisms. A viscous limit on mixing driven by shear turbulence is proposed. Large...
In order to study maternal cardiovascular adjustments to pregnancy, serial determinations were carried out on five pregnant and lour nonpregnant ewes. Measurements were made at approximately two to three week intervals, and continued for nine weeks after delivery. Cardiac output was measured with the dye dilution technique using Evans blue...
To utilize energy resources as efficiently as possible has
become a necessity today. The purpose of this study is to see
how this can be done by extending burnup in a light water reactor.
Specifically, an in-out refueling scheme might extract the maximum
energy from nuclear fuel during its redidence...
This dissertation consists of two essays that address code-sharing alliances in the U.S. domestic airline industry.
The first essay examines the economic impact of code-sharing using data from the complementary code-sharing agreement between Southwest and ATA Airlines. This code-share agreement is found to decrease air fares and increase passenger volumes...
