Tide-topography coupling is important for understanding surface-tide energy loss, the intermittency of internal tides, and the cascade of internal-tide energy from large to small scales. Although tide-topography coupling has been observed and modeled for 50 years, the identification of surface and internal tides over arbitrary topography has not been standardized....
High temperature microchannel heat recuperators (HTμRs) offer an efficient means of improving reactor process thermal efficiency by offering smaller form factors due to increased heat transfer surface area density and volumetric heat transfer rate over traditional heat exchanger designs. To date, HTμRs face cost and reliability challenges. In this work,...
Despite years of research, females continue to have a higher incidence of non-contact ACL injuries. One of the major findings of this research is that males and females perform certain tasks, such as, cutting, landing, and single-leg squatting, differently. In particular, females tend to move the knee into a more...
The combined activities of diverse heterotrophic marine microorganisms significantly shape global biogeochemical cycles, but models of these activities are currently limited to aggregate microbial community processes, and it remains unclear how community structure and the functional roles of specific microbial taxa should be integrated into these models. Therefore, understanding the...

In the formulation of fisheries management plans required under the
Fisheries Conservation and Management Act of 1976 specific attention is
paid to the "capacity" of domestic fishing vessels to harvest the predetermined
optimum yield on an annual basis. Capacity is interpreted in
this thesis as the technical harvesting potential of...
In the study of rebuilding and recovery after natural disasters in the United States, little attention is paid to understanding how and why people rebuild following recurring, small-scale events, like wildfire. Hazard and risk literature, instead, is focused on understanding how larger communities with greater resources, economics, and social capital,...
Implementation fidelity (dosage, adherence, quality of delivery, responsiveness, program differentiation) is the degree to which a program was carried out to its original intent. The following three studies examined the implementation fidelity of a school-based health promotion social and character development (SACD) program. The, Positive Action (PA) program was a...
Contiential margins on plate boundaries are complex systems with morphologies and characteristics dictated by the interplay of sediment deposition and erosion, tectonic faulting, folding, and strong ground motion generating mass wasting events. With ever increasing advances in high-resolution remote sensing techniques these systems are increasingly becoming illuminated.

There are currently three main models used to describe the pattern of hemispheric specialization (i.e., lateralization) for emotion perception: the right hemisphere hypothesis, the valence model, and the motivational model. Although evidence exists in support of all three, the variation between each pattern of results may be due to differences...
Female athletes exhibit three- to six-fold greater incidence of noncontact anterior cruciate ligament (ACL) injury relative to their male counterparts. The increased risk appears to stem from interactions between several risk factors, that can roughly be categorized as anatomic, biomechanical, hormonal, and neuromuscular. Neuromuscular risk factors have recently gained a...
Ultraviolet-B radiation (UVB) is an abiotic stressor in both terrestrial and aquatic systems. The stratospheric ozone layer, depleted due to anthropogenic activities and the cause of elevated UVB at earth's surface over the last four decades, is predicted to recover by 2065. However, UVB levels in aquatic systems may continue...

would simulate the service functions of a counseling center by tracing
students through the center and (2) to...
Plasma concentrations of cortisol, a glucocorticoid hormone that
is immunosuppressive in mammals, increase during stress and
smoltification of salmonids. There was a reduction in the ability of
lymphocytes to generate antibody producing cells (APC) in vivo
concurrent with increased plasma cortisol titers during smoltification
of coho salmon (Oncorhvnchus kisutch). Cortisol...
Periodic determinations of plasma hormone levels suggested that changes in interrenal activity are unrelated to changes in thyroidal or gonadal activity during development (smoltification) of juvenile coho salmon (Oncorhynchus kisutch). Moreover, in an experiment where fish were reared under various conditions of crowding and water inflow rate, it appeared that...
The extreme value index (EVI) links the generalized extreme value (GEV) distribution and the generalized Pareto (GP) distribution. These two distributions are fundamental in extreme value theory (EVT), with the GEV distribution being the only possible non-degenerate limiting distribution of properly normalized maxima of iid random variables, and the GP...

The immune toxicity of 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) has been studied for over 35 years, but only recently has the profound immune suppression associated with TCDD exposure been linked to induction of regulatory T cells (Tregs). The effects of TCDD are mediated through binding the aryl hydrocarbon receptor (AhR), a ligand-activated transcription...
The developmental milestones of Sustainability are consistent with the post-normal versus traditional science, where transdisciplinary and policy/action research are among the important approaches to be added to traditional analysis. This shift requires a new perspective to look at the problem at hand: we are no longer considering a group of...
Chlordecone belongs to the class of persistent organochlorine pesticides that are remarkably resistant to environmental degradation. Even though their use was banned in the United States in 1978, these compounds can still be detected in both humans and wildlife throughout the world. Previous work has shown that the pretreatment of...
Body size explains much of the interspecific variation in the physiology, behavior, and morphology of birds, such as metabolic rate, diet selection, intake rate, gut size, and bill size. Based on mass-specific metabolic requirements and relative energetic costs of activities, being a certain body size has both advantages and disadvantages....
