The effects of clonal variability, crown position of cones, and top-pruning of ramets to reduce height growth, on 1) the proportion of viable self-fertilized progeny (s) and 2) the proportion of filled seeds (PF), were investigated in a 20 year-old Douglas-fir (Pseudotsuga menziesii [Mirb.1 Franco) seed orchard. Cones were collected...
High purity niobium metal is used in the construction of superconducting radio frequency (SRF) cavities in superconducting particle accelerators, such as the Large Hadron Collider (LHC) at CERN or the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory. The usual method for characterizing the impurities in this niobium, the...
As manufacturing advancements continue to develop, designers must be able to consider these technologies during the design process. Unfortunately, many of these new technologies, such as additive and advanced joining, have many nuances that require expert knowledge to effectively apply. Additionally, new design techniques, such as topology optimization, allow users...
Poor material utilization is inherent to conventional manufacturing processes, leading to high material waste and machining times. Additive manufacturing processes attempt to solve this issue by allowing production of near-net shapes, but the processes may be too expensive or infeasible. By leveraging both processes in a single part, the waste...
An experiment was conducted to determine the effect of dietary copper (Cu)
on Cu status and lipid metabolism in Holstein and Jersey cattle. Eight Jersey and8
Holstein cows in mid-lactation were blocked by days in milk (169 ± 37) and
assigned at random to one of two diets. Cows received...
This thesis study attempts to differentiate between attention and
understanding as separate phases of communication theory. To do this,
additional analysis was made of data already gathered from a random
sample of Oregonians by the Survey Research Center at Oregon State University.
An additional objective was to determine the role...
Integrated manufacturing systems, a combination of subtractive, additive, and joining processes, provide a competitive advantage for manufacturing organizations. As product designs become more complex and capital more scarce, an ideal combination of advanced manufacturing technologies (e.g., powder bed fusion or friction welding), in tandem with traditional subtractive manufacturing systems, can...
Quaking aspen, Populus tremuloides, has experienced severe declines in recent years in part due to the effects of changing climate and extreme drought. As the dominant deciduous tree in Western North American forests, aspen plays a critical role in forest biodiversity and ecosystem function. Therefore, the persistence of this species...
This thesis is a qualitative study of the social justice practice of experienced student affairs professionals employed in higher education. If we are to be truly supportive of all of our students, as is paramount in the values of student affairs professionals (Komives et al., 2003), systemic change is needed...
