The enzymes and pathways involved in the catabolism of
glucose by several strains of Streptococcus diacetilactis, Streptococcus
cremoris, and Streptococcus lactis, commonly called the
lactic streptococci, were studied. The presence of aldolase,
triosephosphate isomerase and alcohol dehydrogenase in these
organisms provided evidence for the operation of the Embden-Meyerhof-Parnas (EMP) pathway...
Most studies of bacteria in water have concerned public health; little attention has been given to organisms which are indigenous to
the aquatic environment. Myxobacteria are known to occur in soil,
in the marine environment, and several have been studied in relation
to diseases of salmonid fishes. However, little information...
Affective reactions to daily stressors are known mechanisms through which daily stressors impact health and well-being (e.g., Charles et al., 2013; Piazza et al., 2013; Sin et al., 2015; Stawski et al., 2019). Therefore, understanding what may promote resilience or vulnerability to such affective reactions is imperative. Theoretical perspectives (Almeida,...
This MPP essay examines how states expand access to nutritious food for low-income families, focusing specifically on policies related to the Supplemental Nutrition Assistance Program (SNAP) and farmers’ markets. Coalitions made up of nonprofits focused on hunger, farmers, and health collaborate to impact relevant policies in their respective states. The...
Sustainability has become an unprecedented priority in global manufacturing due to the growing concerns over issues such as an aging workforce, environmental degradation, and public health. The simultaneous consideration of the economic, environmental, and social aspects – often referred to as the “three pillars of sustainability” – is crucial to...
The purpose of this study was to examine the meal management
practices used in the homes of selected home economics graduates.
A total of 296 questionnaires were mailed to Oregon State University
home economics graduates for the years 1945, 1950, 1955, and 1960.
Forty-nine percent (146) of the questionnaires were...
The design, development, and utilization of a direct shear test
apparatus is presented in this thesis. The effectiveness of the
device for determining the friction angle stress state parameter is
studied. Two materials, alumina and uranium dioxide, were tested.
Alumina microspheres were employed in the initial experiments
to simulate the...
The use of size and shape tunable quantum confinement nanocrystals has many potential applications for use in semiconductors, optics and sensors. The synthesis of lead sulfide (PbS) and copper indium diselenide (CuInSe₂) nanoparticles are of particular interest for use in semiconductor, optoelectronics and bio-medical applications.
The continuous synthesis of lead...
As ornamental container nurseries face diminishing water allocations, many are looking to automated irrigation solutions to increase their water application efficiency. This thesis presents the findings of a study conducted at a commercial container nursery to determine 1) whether a capacitance or load cell sensor was better suited for monitoring...
