Twenty-six Holstein and 18 Jersey multiparous cows in a randomized block design were assigned by calving date and breed to a non-anionic prepartum diet (CTRL) or a treatment diet containing a commercial anionic salt supplement (Animate®). Control and treatment diets were formulated to a dietary anion-cation difference (DCAD) of 21.3...
Human activities are causing profound changes to the global environment, yet the potential consequences of these changes on rising atmospheric carbon dioxide and climate change are not well understood. Improving our understanding of these processes requires an enhanced awareness of how global ecosystems are changing and how these changes affect...
Two experiments were conducted to evaluate the influence of a yeast-derived cell wall preparation (YCW) on forage intake and digestibility, ruminal fermentation characteristics, serum prolactin and prolactin stores, and milk production in beef cattle consuming high-alkaloid tall fescue straw. In Exp. 1, 16 Angus x Hereford ruminally cannulated steers (200...
The number of women diagnosed with diabetes, including gestational diabetes, will continue to increase in the face of epidemic rates of obesity. The concurrent rise in obesity and diabetes makes it important to determine the risk factors for gestational diabetes mellitus (GDM) and the nature and extent of care offered...
A. W. N. Pugin was a driving force in the Gothic Revival movement in England during the first half of the nineteenth century. He was an architect and a writer who expounded on the virtues of reviving Gothic architecture, not only for its reflection of the sacred mystery of ancient...
There has been an increasing realization of the value of innovativeness, the orientation toward innovation, for firms thriving to gain competitive edge. The US forest products industry is no different in this respect and many companies have active initiatives to bring about creativity from their own employees. At the same...
Oxygen derived radicals are involved in many aspects of life from aging and cell signaling to disease states as diverse as heart disease, diabetes, neurodegeneration and inflammation. Therefore, understanding the function of antioxidant defense proteins and the effects of oxygen derived radicals on protein function is essential to elucidate the...
Inner-shelf circulation and mechanisms of across-shelf transport of water masses were examined using seven years of observations collected by the Partnership for Interdisciplinary Studies of Coastal Oceans (PISCO) program, a long-term monitoring effort along the central Oregon coast. Since 1998, moored velocity and hydrographic measurements have been obtained during the...
To identify factors limiting 'Candidatus Pelagibacter ubique' maximum cell density and growth rate in pure culture on seawater, the genome sequence of 'Cand. P. ubique' was analyzed, culturing experiments with organic and inorganic nutrient additions were made, and radiotracer uptake experiments were performed. The genome was sequenced, custom data mining...
This study has two main objectives. First, we propose an alternative way for treating deposits in modeling a banking firm, which account for both their input and output features. Second, we contribute to modeling failures in the banking sector by distinguishing three groups of factors affecting failures: bank level, industry...
Dendrimers are nanoscale macromolecules that have highly branched, core-shell structures. Higher generation dendrimers have close-packed peripheral functional groups and a hollow interior. The chemistry of the core and the terminal functionalities can be tailored according to the specific application. These structural characteristics provide room for the design of dendrimers to...
The northwestern corner of the Basin and Range Province (NWBR) lies in southeast Oregon where extensive Late Miocene, mafic to bimodal basalt-rhyolite volcanism and extensional faults dominate a stark and arid landscape. Near Lake Abert, the Late Miocene volcanic section abuts Early Miocene, dominantly intermediate composition volcanoes at the Coleman...
The phenolic profile of pineapple juice was analyzed by reverse-phase HPLC/Diode Array Detector, and 9 major peaks accounting for 70% of total peak area were characterized. None of these peaks are represented by the pineapple phenolics reported to be present by previous workers. Most of the major peaks are not...
In this dissertation, I present the work of developing more efficient and economical techniques for fragmenting large bio-molecules, and ultimately making mass spectrometry a more powerful tool in proteomics, DNA sequencing, and other areas of biomolecular analysis.
Aiming at lowering the installation and operating cost, and delivering electron capture dissociation...
Deaf students in mainstream colleges are withdrawing at an alarming rate. Approximately 70% of the 123,000 deaf students enrolled in 2,300 colleges across the United States will not persist until graduation. This qualitative study examined what factors in the academic and social environment are linked to deaf college students' perceptions...
Early intervention services promote children's optimal health. The benefit of early intervention is invaluable to society for years to come. One important step in providing early intervention is the identification of children who need early intervention services. In Taiwan, the lack of a culturally appropriate, reliable, and valid child developmental...
Shaped by life course and feminist perspectives, this study investigated the influence of finances, human capital, health, family situations, and work factors on two different retirement transitions among married and partnered men and women. Because women and men arrive at retirement under different life circumstances, logistic regression analyses were conducted...
Systems biology is becoming increasingly important for the study of living organisms. It focuses on the mathematical understanding of biological systems. Cells, the basic units of all living creatures, are biological systems of major interest. Considerable work is being done towards modeling cells as mathematical systems. At the same time,...
This thesis investigates the behavior of major inorganic nutrients (P, N, Si), trace metals (Mn, Fe), and alkaline-earth metals (Ba) within Tillamook Bay over seasonal cycles and under a range of river discharge conditions from October 1997 through December 1999. Located in the Pacific Northwest region, Tillamook Bay is an...
This dissertation focuses on science relevant to the design and implementation of marine reserves. The chapters explore a range of topics related to among-site variation in population, community, and ecosystem dynamics. My results demonstrate the value and feasibility of integrating this knowledge into more comprehensive conservation and management approaches. While...
