Channel-Levee Complexes And Sediment Flux Of The Upper Indus Fan, Taylor Landry Berlin Jan 2014

Channel-Levee Complexes And Sediment Flux Of The Upper Indus Fan, Taylor Landry Berlin

LSU Master's Theses

The Indus Fan with a volume of 4.5 million km³ is the second largest submarine fan on Earth, only behind its neighbor to the east The Bengal Fan. It formed off the passive margin of Pakistan-India in the northern Arabian Sea. One of the more important aspects of the Indus Fan is its mostly complete sediment record of what has been eroded from the western Himalayan and Karakoram Mountains which act as the main source for the Indus River system. Since the initiation of the Himalaya about 50 Ma, sedimentation rates have fluctuated. This study attempts to calculate a new …

I Need A Doctor: A Critique Of Medicare Financing Of Graduate Medical Education, Stacey A. Tovino Jan 2014

I Need A Doctor: A Critique Of Medicare Financing Of Graduate Medical Education, Stacey A. Tovino

Scholarly Works

In its broadest sense, this Article examines the complex relationship between population booms, doctor shortages, and United States government financing of graduate medical education (GME). More specifically, this Article argues that current rules governing the calculation of Medicare payments to teaching hospitals for the costs of GME are based on cost, population, and other data that are no longer relevant. As applied, these formulas discriminate in favor of the nation's oldest teaching hospitals, located in New England and the Middle Atlantic, and against current and future teaching hospitals located in growing population centers, especially regions in the South and West. …

Nutrient And Sediment Effects On Oligohaline Marsh Plant Community In Mississippi River Delta, Sareh Poormahdi Jan 2014

Nutrient And Sediment Effects On Oligohaline Marsh Plant Community In Mississippi River Delta, Sareh Poormahdi

LSU Master's Theses

The Mississippi River Delta comprises approximately 40% of the coastal wetlands in the conterminous United States, but has experienced more than 80% of the wetland loss in part due to flood control levees that have hydrologically isolated the lower River from the adjacent wetlands for a century. Thus, reconnecting the River to the wetlands through diversions is one of the approaches being used to reduce the rate of wetland loss. However, the diversion structures were originally designed to deliver freshwater rather than sediment. Furthermore, nutrient concentrations in the River water have increased during the past half-century as a result of …

Lost In The Shuffle: How Health And Disability Laws Hurt Disordered Gamblers, Stacey A. Tovino Jan 2014

Lost In The Shuffle: How Health And Disability Laws Hurt Disordered Gamblers, Stacey A. Tovino

Scholarly Works

Gambling disorder is not a legally sympathetic health condition. Health insurance policies and plans have long excluded treatment for gambling disorder from health insurance coverage. Individuals with gambling disorder who seek disability income insurance benefits from public and private disability income insurers also tend not to be successful in their claims. In addition, federal and state antidiscrimination laws currently exclude individuals with gambling disorder from disability discrimination protections. This Article is the first law review article to challenge the legal treatment of individuals with gambling disorder by showing how health insurance and antidiscrimination laws hurt problem gamblers. Using neuroscience, economics, …

Center for Lakes and Reservoirs Publications and Presentations

In recent years, public awareness of aquatic invasive species (AIS) has increased considerably in Oregon and elsewhere in the western U.S.. News articles, boat inspection stations and AIS permit programs have drawn attention to the threat of aquatic invasive species, especially animals like zebra mussels (Dreissena polymorpha), quagga mussels (Dreissena bugensis), and New Zealand mudsnails (Potamopyrgus antipodarum). However, invasive aquatic plants are also capable of causing severe impacts and may similarly be transferred between waterbodies on boats, trailers or other equipment. Heavy infestations can hinder recreational use by motorized and non-motorized boats, snag fishing lines, threaten the safety of swimmers …

A Toolkit For Tracking And Mediating Parametric Objects Upon Commodity Mobile Devices, Shantanu Thatte Jan 2014

A Toolkit For Tracking And Mediating Parametric Objects Upon Commodity Mobile Devices, Shantanu Thatte

LSU Master's Theses

The large number of mobile devices introduced in the market in recent years provide numerous interaction opportunities. We used commercially available products to create an interface for interaction with diverse datasets. We extended this scenario to include multiple physical instances, realizing a real-time multi-party interaction session. Tangibles act as tools and containers, in a fashion that requires their physical location and orientation to be evaluated continuously during a session. We present a technique to detect an object using only the touchscreen of a mobile device as an input, by means of touch patterns created on the screen. This helps avoid …

Exponentially Convergent Generalized Finite Element Method For Multi-Scale Problems, Xu Huang

LSU Doctoral Dissertations

The overall approach I take in the thesis falls into the category of multiscale finite element methods(MsFEM). I work to identify a new class of local approximation spaces with good approximation properties. This is carried out for the equilibrium problem of linear elasticity. The choice of local approximation spaces is motivated by the kolmogorov n-width. Part of my thesis work develops an estimate to show that it is possible to achieve a local approximation error of ô with respect to the energy norm using at most lnd+1 &frac1ô local basis functions. The global approximation error ôis controlled by the …

Modeling Near Surface, Gas-Induced Seafloor Deformation Using Thin Plate Mechanics In The Thunder Horse Oil Field, Gulf Of Mexico And Ninilchik Field, Cook Inlet Basin, Alaska, Michael I. Thoma

LSU Master's Theses

Seabed topographic expressions such as pockmarks and domes caused by the vertical migration and accumulation of methane are found in muddy, cohesive sea beds around the world. These surface features range from 10-1000 m in diameter and 1-20 m in relief (Judd and Hovland, 2007). The mechanics of soft, cohesive sediment deformation due to overpressure from rising gas is not well understood or quantitatively defined despite the hazards they present to offshore drilling. Shallow gas pockets and overpressured sediments formed by the migration of subsurface gas to the seafloor can cause drilling blowouts, resulting in the release of large amounts …

Untangling Earth System Responses Recorded In Sulfate's Sulfur And Oxygen Isotopes At The Dawn Of Multicellular Life And Today, Bryan Alan Killingsworth Jan 2014

Untangling Earth System Responses Recorded In Sulfate's Sulfur And Oxygen Isotopes At The Dawn Of Multicellular Life And Today, Bryan Alan Killingsworth

LSU Doctoral Dissertations

Major Earth system perturbations in the deep past and today are recorded in sulfate sulfur and oxygen isotopes, as examined here in three cases. (1) Sedimentary sulfate record of the “Marinoan Oxygen-17 Depletion” (MOSD) event, implies ultra-high CO2 atmosphere at ~635 Ma after global glaciation. MOSD duration is constrained by correlating its most complete record to radiometric dates. Barium sulfate layers in South China sediments show the MOSD in lower layers but persistently absent up section. Carbon-13 correlation locates the MOSD within dated intervals from other sites, yielding a 0 - 0.99 Myr duration. Thus, sedimentary constraint on this non-steady-state …

Characterization Of A Water Soluble, Non-Ionic, Helical Poly(Α-Amino Acid), Wayne Huberty Jan 2014

Characterization Of A Water Soluble, Non-Ionic, Helical Poly(Α-Amino Acid), Wayne Huberty

LSU Doctoral Dissertations

A water soluble, non-ionic, rodlike polymer, PEGL, was synthesized and characterized in efforts to synthesize a novel model polymer to study stiff polymers in solution. The rodlike system is likely stiff due to a high relative percent helicity in water up to 50 °C, measured by circular dichroism, the observation of liquid crystalline domains in water, and from the slope measured from conformation plots supplied by GPC/MALS; however, it also apparent the system is aggregating in both a 2 mM azide solution and a buffer (200 mM NaNO3 + 20 mM NaH2PO4 + 2 mM NaN3), in corroboration of negative …

Space-Time Statistical Analysis Of Malaria Morbidity Incidence Cases In Ghana: A Geostatistical Modelling Approach, Simon K. Appiah

Theses: Doctorates and Masters

Malaria is one of the most prevalent and devastating health problems worldwide. It is a highly endemic disease in Ghana, which poses a major challenge to both the public health and socio-economic development of the country. Major factors accounting for this situation include variability in environmental conditions and lack of prevention services coupled with host of other socio-economic factors. Ghana’s National Malaria Control Programme (NMCP) risk assessment measures have been largely based on household surveys which provided inadequate data for accurate prediction of new incidence cases coupled with frequent incomplete monthly case reports. These raise concerns about annual estimates on …

Research outputs 2014 to 2021

Although studies of seed banks in arid ecosystems are commonplace, they are lacking for the large arid zone of Western Australia. Across the six major plant communities fringing a large salt lake within this zone, topsoil (0-5 cm depth) was collected from 12 to 36 sites per community. Samples were dried, spread out on a bed of vermiculite in seedling trays and placed in a well-watered glasshouse to determine the readily germinable component of the soil seed bank. Subsamples of topsoil were treated with smoke water, hot water or flooding to help determine seed bank of species with dormancy mechanisms. …

Mori, Lawrence J. Beilin, Wendy H. Oddy, Alexandra P. Bremner, Therese A. O'Sullivan

Research outputs 2014 to 2021

Almost all previous studies examining the associations between glycaemic load (GL) and metabolic syndrome risk have used a daily GL value. The daily value does not distinguish between peaks of GL intake over the day, which may be more closely associated with the risk of the metabolic syndrome. The aim of the present study was to investigate the cross-sectional associations between daily and mealtime measures of GL and metabolic syndrome risk, including metabolic syndrome components, in adolescents. Adolescents participating in the 14-year follow-up of the Western Australian Pregnancy Cohort (Raine) Study completed 3 d food records and metabolic assessments. Breakfast …

The Acquisition Of Expertise In The Classroom: Are Current Models Of Education Appropriate?, Craig P. Speelman Jan 2014

The Acquisition Of Expertise In The Classroom: Are Current Models Of Education Appropriate?, Craig P. Speelman

Research outputs 2014 to 2021

The study of expertise tends to focus on humans who can perform extraordinary feats. Although the way in which expertise is acquired is often characterized as similar to everyday skill acquisition, the attainment of basic numeracy skills is rarely considered in the same context as the attainment of expertise. It is clear, though, that average numeracy skills possess all the hallmarks of expert performance. In this paper I argue that the traditional classroom of Western education systems pays insufficient attention to the idea that effective numeracy skills represent a level of expertise that requires a particular form of training. Using …

Characterizing The Resolvability Of Real Superluminescent Diode Sources For Application To Optical Coherence Tomography Using A Low Coherence Interferometry Model, Paul V. Jansz, Steven Richardson, Graham Wild, Steven Hinckley

Research outputs 2014 to 2021

The axial resolution is a critical parameter in determining whether optical coherent tomography (OCT) can be used to resolve specific features in a sample image. Typically, measures of resolution have been attributed to the light source characteristics only, including the coherence length and the point spread function (PSF) width of the OCT light sources. The need to cost effectively visualize the generated PSF and OCT cross-correlated interferogram (A-scan) using many OCT light sources have led to the extrinsic evolution of the OCT simulation model presented. This research indicated that empirical resolution in vivo, as well as depending on the light …

Research outputs 2014 to 2021

Pit lakes may form when open cut mining leaves a pit void behind that fills with ground and surface water. Often replacing terrestrial ecosystems that existed prior to mining, the pit lake may offer an alternative ecosystem with aquatic biodiversity values that can be realised through planned restoration. Restoration theory and mine closure regulatory requirements guides us toward restoring disturbed systems towards landscapes that are of regional value and relevance. However, how do we identify a restoration target for a novel aquatic habitat that did not exist prior to the new post-mining landscape? This paper presents a process of first …
