Comparison Of The Effects Of Growth Hormone On Mac-T Cells And Primary Mammary Cells, Lisa Mcdonnell, Tasha Johnson, Daniel G. Peterson
Comparison Of The Effects Of Growth Hormone On Mac-T Cells And Primary Mammary Cells, Lisa Mcdonnell, Tasha Johnson, Daniel G. Peterson
Animal Science
The ability of growth hormone (GH) to increase milk yield through somatomedins is well characterized,however recent studies utilizing mammary epithelial cell (MEC) lines have indicated a possible direct effecton MEC. In the mammary alveolar cell-T (MAC-T) line, relative abundance of mRNA for two milk protein genes, α-lactalbumin and αS1-casein, and GH receptor was increased by GH. MAC-T cells were compared tobovine mammary tissue explants and primary MEC isolated from raw milk through culture in classicallactation medium (dexamethasone, insulin, prolactin) with 0 or 10 ng/mL GH. Explant and primary cellmRNA abundance showed a similar pattern to MAC-T indicating that the effects …
The Cyber Security Threat, Jens Pohl
The Cyber Security Threat, Jens Pohl
Architecture
There is justified concern that the Information Technology (IT) infrastructures of the United States (US) and probably all countries in the world are not secure. Our digital national security infrastructure is routinely penetrated. Some of these attacks have compromised critical systems supporting our troops in Iraq and Afghanistan. Defense contractor networks that store information vital to our national security are being attacked with increasing frequency (Harbiger 2010). In 2007 some unknown adversary broke into the Department of Defense, Department of State, and Department of Commerce networks, and probably the Department of Energy and NASA as well (CBS 2009). In April …
Finite Element Analysis And Modeling Of A .38 Lead Round Nose Ballistic Gelatin Test, Danielle Datoc
Finite Element Analysis And Modeling Of A .38 Lead Round Nose Ballistic Gelatin Test, Danielle Datoc
Master's Theses
Firearms are present in two-thirds of United States households. As of 2003, roughly 500,000 projectile wounds occur annually in the United States. This costs an estimated 2.3 billion dollars of medical spending. The best treatment of gunshot wounds relies heavily on experience, but even with experience the unpredictable nature of ballistics can make treatment difficult.
Wound ballistics studies the injury pattern of a particular bullet. Ballistic gelatin tests are used to analyze this pattern. A block of 10 or 20% ballistic gelatin is set and a bullet is fired through the block. Key characteristics of the wound profile seen in …

An Investigative Study Into The Relationship Of Bone Morphogenetic Protein Antagonist Expression And Osteocyte Density By Region And Quadrant, Scott C. Mosher
Master's Theses
The role of cytokines and cell behavior and viability with respect to bone remodeling and bone behavior is an exciting area of orthopedic research. The purpose of this study was to investigate the relationships between BMP antagonist expression and osteocyte density, lacunar densities and osteocyte viability in cortical bone. Samples of unloaded tibial bone obtained from six C57Bl/6 mice were immunohistochemically stained for gremlin and noggin expression and also underwent methyl green staining to determine osteocyte presence. Bone sections were divided into four quadrants (cranial, caudal, medial and lateral) and three regions (proximal, mid shaft and distal), followed by analysis …
Biomechanical Comparison Of Wire Circlage And Rigid Plate Fixation For Median Sternotomy Closure In Human Cadaver Specimens, Mark Steven Wong
Biomechanical Comparison Of Wire Circlage And Rigid Plate Fixation For Median Sternotomy Closure In Human Cadaver Specimens, Mark Steven Wong
Master's Theses
Background:
Over 700,000 patients per year undergo open-heart surgery. Healing complication rates can be up to 5% of patients who undergo this procedure, with a morbidity rate of 50% if mediastinitis supervenes. A secure and rigid fixation of surgically divided sternum is critical to avoid healing complications. The purpose of this study was to compare the yield load, construct stiffness, ultimate load, displacement at ultimate load, and post-yield behavior of three sternotomy closure methods (Peristernal wires or Sternalock titanium plates) when stressed in each of three directions: lateral distraction, rostro-caudal (longitudinal) shear distraction, and anterior-posterior (transverse) shear in a cadaveric …

Consumers And Benefits Of Genetically Modified Vegetables, Megan Carter Judge
Consumers And Benefits Of Genetically Modified Vegetables, Megan Carter Judge
Master's Theses
With the adoption of biotechnology in many agricultural products with first-generation biotechnology traits such as increased pest resistance, greater herbicide resistance, and increased yields the growers have accepted them. The next wave of biotech crops have second-generation traits, such as improved nutrient content, extended shelf life, reduced pesticide and herbicide application (a consumer demanded trait), and better taste. Will these consumer benefits offset any concern that the consumer has regarding biotechnology? What are those benefits and how should the information be communicated to the consumer?
Three focus groups give insight to the proposed questions. The focus groups were done in …
Explaining Prehistoric Variation In The Abundance Of Large Prey: A Zooarchaeological Analysis Of Deer And Rabbit Hunting Along The Pecho Coast Of Central California, Brian F. Codding, Judith F. Porcasi, Terry L. Jones
Explaining Prehistoric Variation In The Abundance Of Large Prey: A Zooarchaeological Analysis Of Deer And Rabbit Hunting Along The Pecho Coast Of Central California, Brian F. Codding, Judith F. Porcasi, Terry L. Jones
Social Sciences
Three main hypotheses are commonly employed to explain diachronic variation in the relative abundance of remains of large terrestrial herbivores: (1) large prey populations decline as a function of anthropogenic overexploitation; (2) large prey tends to increase as a result of increasing social payoffs; and (3) proportions of large terrestrial prey are dependent on stochastic fluctuations in climate. This paper tests predictions derived from these three hypotheses through a zooarchaeological analysis of eleven temporal components from three sites on central California’s Pecho Coast. Specifically, we examine the trade-offs between hunting rabbits (Sylvilagus spp.) and deer (Odocoileus hemionus) …

Bacteria - The Last Stronghold Of Lamarckism?, William D. Stansfield
Bacteria - The Last Stronghold Of Lamarckism?, William D. Stansfield
Biological Sciences
French naturalist J.B. Lamarck is most commonly known for popularizing the theory that some traits acquired during the life of an organism can be inherited in his 1809 book. German biologist A. Weismann presented evidence in his 1891 book that acquired traits were not heritable in sexually reproducing animals. But so little was known about bacteria that they were considered to be the last stronghold of Lamarckism. The “fluctuation test” of S. Luria and M. Delbrück in 1943 seemed to confirm that Lamarckism in bacteria was indeed dead. This review, however, proposes that today bacteria may be viewed as the …
Effect Of Sand Grain Size On Burrowing Behavior Of Juvenile Pacific Sand Crabs (Emerita Analoga), Natalie A. Lee, Laura M. Melroy
Effect Of Sand Grain Size On Burrowing Behavior Of Juvenile Pacific Sand Crabs (Emerita Analoga), Natalie A. Lee, Laura M. Melroy
Biological Sciences
Emerita analoga, Pacific coast sand crabs, are an important biological component of the swash zone ecosystem. They have evolved the ability to burrow into sand, and burrowing speed is commonly used as an indicator of performance relevant for fitness in this species. Sand grain size varies among beaches, and crabs may be better adapted to to burrow in some sand types. We performed a completely crossed 3-factor experiment to determine how the sand grain size associated with beach-of-origin and rearing conditions influence burrowing in coarse and fine sand. Crabs from a fine sand beach and a coarse sand beach were …
Christ Being Hopkins And Hopkins Being Christ, Cory Ames
Christ Being Hopkins And Hopkins Being Christ, Cory Ames
English
This paper compares and contrasts Gerard Manly Hopkins’ sonnet “As Kingfishers Catch Fire, Dragonflies Draw Flame” to the “terrible” sonnet “Carrion Comfort.” It asserts that since both sonnets explore opposite ends of a paradoxical relationship between man and Christ, which Hopkins often meditated over, both sonnets should work together as spiritual complements of one another, rather than proof of Hopkins’ spiritual derailment.
'The Father Of Us All': The Cold War Liberalism Of Reinhold Niebuhr And The Paradox Of America's Moral Insecurity, Kendall S. Eyster
'The Father Of Us All': The Cold War Liberalism Of Reinhold Niebuhr And The Paradox Of America's Moral Insecurity, Kendall S. Eyster
History
145 years after Lincoln's Second Inaugural Address, there has been a flood of interest in theologian Reinhold Niebuhr, and his awareness of the potential hubris in waging a struggle against extremism. His constantly shifting positions on liberalism and America’s global stature has led to disagreement between historians and politicians who claim his legacy on both ends of the political spectrum. What is indisputable, however, is Niebuhr’s belief in liberalism’s epistemological debt to the ideals of Christianity and the repudiation of America’s history as merely a blueprint for democracy that should be repeated, sui generis, elsewhere.
