Fabricated steel beam specimens with rectangular holes cut in
the webs were subjected to load tests to analyze the behavior of the
modified section. Beam-depth to hole-depth ratio was in all cases
2.0; however, ratio of hole length to hole height varied from 2.0 to
3.0. The primary instrumentation of...
Wildfires across the Western United States, specifically in California have increased in size and intensity in recent decades. These fires are encroaching on California’s Wildland Urban-Interface (WUI), often with devastating results. Most recently, these destructive results were displayed in the 2018 fire season in the Camp and Carr Fires and...
The purpose of this study was to determine: what factors
are important in influencing adult students to participate in
distance learning programs; 2) whether students prefer interactive
television or instructional television.
A review of the literature identified items that were
considered Important to students participating in distance learning
programs. The...
Gall-associated phytopathogens have unique evolutionary histories that haveshaped both their modes of infection and genomic structures. Pathogenicity of the gall-associated plant pathogens of the Rhodococcus, Agrobacterium, and Rathayibactergenera is mediated by horizontally acquired virulence loci. The relative ease of gainand loss of the virulence loci has confounded accurate characterization of...
Methane is a product of biogeochemical processes which respond to changes in climate. The history of atmospheric methane is recorded by ice cores providing insight into past changes in these biogeochemical processes. This dissertation is comprised of three studies which focus on centennial- and millenial-scale variability of methane from ice...
Freezing is one of the important technologies for preservation of foods.
In this project, using surimi as a food model, thermophysical properties of frozen
foods were evaluated and the freezing process was simulated using a finite
element package.
To measure temperature-dependent thermal conductivity, a line-source
probe system was used. Effects...
