Synthesis And Characterization Of Cobalt-Platinum Thin Films, Priya David Jan 2005

Synthesis And Characterization Of Cobalt-Platinum Thin Films, Priya David

LSU Master's Theses

Co-based alloy thin films have attracted a lot of interest, due to their excellent magnetic properties, that is essential in the field of magnetic recording media. Alloying Co with metals like Pt changes some of its intrinsic magnetic properties such as increasing the magnetocrystalline anisotropy constants of the alloy.

Hemodynamic And Ocular Responses To Caloric Stimulation And Age-Related Disparities, Melissa J. Deveer Jan 2005

Hemodynamic And Ocular Responses To Caloric Stimulation And Age-Related Disparities, Melissa J. Deveer

LSU Master's Theses

Age-related declines in vestibular function affect balance and coordination in older adults. Of perhaps equal importance, but less understood, are the potential implications of vestibular degeneration on cardiovascular homeostasis. Recent evidence suggests that the semi-circular canals, a section of the vestibular system, may be involved in the vestibulosympathetic reflex (VSR), but the extent to which the aging of the semi-circular canals interferes with cardiovascular homeostasis is unknown. Activation of the intact VSR results in increases in tonometric blood pressure (TBP) and heart rate (HR) as well as decreases in cardiac output (Q) and pre-ejection period (PEP). The purpose of this …

American Disillusionment And The Search For Self-Fulfillment In The 1970'S: A Cultural History Of Taxi Driver, Annie Hall, And Saturday Night Fever, Joshua Elliot Lubin

LSU Master's Theses

Three popular and critically acclaimed films of the post-Watergate era illustrated and criticized the period’s disillusionment. Likewise, a series of political and economic crises spawned a shift in American culture. The Sixties’ mass social movements dissolved into the Seventies and launched a trend in which Americans became preoccupied with themselves more than the state of the nation. Controlling one’s own destiny became a collective obsession when confronted with the period’s various political and economic ailments. The “Me” decade turned inward rather than concern itself with public issues. Therefore, American culture earned dubious labels such as narcissistic and decadent from critics …

Mesoscopic Simulation Of Grain Boundary Diffusion Creep In Inhomogeneous Microstructures, Kanishk Rastogi

LSU Master's Theses

At high temperatures, stresses well below the material’s tensile yield strength can induce permanent deformation over a period of time. This time-dependent progressive deformation of a material at constant stress is called Creep and is observed in both crystalline and non-crystalline solids. The principal deformation processes contributing to creep deformation are slip, sub-grain formation and grain-boundary sliding. Mechanisms involving creep of crystalline materials involve either dislocation motion or diffusional flow of atoms or both. Extensive studies have been done to ascertain the creep mechanism in various regimes of temperature and applied stresses. At low stresses and high temperatures, grain boundary …

The Effects Of Aluminum Concentration On Growth Responses In Six Spartina Alterniflora Genotypes, Daniel Farrell Becker Jan 2005

The Effects Of Aluminum Concentration On Growth Responses In Six Spartina Alterniflora Genotypes, Daniel Farrell Becker

LSU Master's Theses

Elevated soluble aluminum concentrations can adversely affect plant growth. During a drought, wetland soils may experience higher than normal soluble aluminum due to the oxidation of metal sulfides and resulting decreases in pH, which mobilizes metallic cations. Louisiana coastal salt marshes were subject to a record-setting drought in the winter and spring of 2000 which was coincident with the die-off of large expanses of salt marsh, termed " brown marsh ". Spartina alterniflora was the primary plant species affected. However, because some individuals within large areas of die-off survived the brown marsh event, they may have been the more resistant …
