Forced Bubble Columns, Jia Ma

LSU Master's Theses

In many chemical, biochemical and pharmaceutical industrial processes, bubble breakage is very important for gas component to dissolve and react with surrounding liquid. The overall mass transfer performance can be improved greatly when the interfacial gas-liquid area is increased due to bubble breakup. In forced bubble columns operating at low forcing frequency (<30Hz) and small forcing amplitude (<3mm), bubbles undergo phenomenal breakage. Mass transfer coefficient, kLa, is increased to 250%~625% of the no forcing value depending on flow regime and configuration of membrane and piston. Two different mechanisms, induced shear slug breakage in the gas feeder tube for bubbly flow and resonant frequency bubble breakage in the column fluid phase for jet flow, seem to at work.

There were two sequences of data collection: the first consisted of two surveys sent to online teachers and another to students enrolled in online courses in three academic colleges. The second sequence of interviews with nine experienced online teachers provided a …

Shenpi (Licensing) Reform From The Perspective Of One Municipal Jurisdiction: Ideologies, Institutions, And Law, Wei Cui

All Faculty Publications

The Administrative Licensing Law (xingzheng xuke fa) will constitute a major addition to Chinese administrative law, and the rhetoric surrounding its drafting promises path-breaking reform of the Chinese regulatory state. This report critically assesses that promise by chronicling the actual course of shenpi (licensing) reform carried out in Shenzhen in 2001. Shenpi reform derives its novelty from questioning the rationale of regulatory policies and not just the procedures by which they are carried out. In Shenzhen, however, the reform revolved around an effort to achieve quantitative reduction in the number of shenpi procedures, which could reflect either changes in the …

Estimation Of Waterfowl Food Abundance In Coastal Freshwater Marshes Of Louisiana And Texas, Christian Jesse Winslow

LSU Master's Theses

Food abundance might limit survival or recruitment of wintering waterfowl. Nutritional requirements of wintering waterfowl have been estimated, but there are insufficient data on the abundance of seeds and submerged aquatic vegetation (SAV) to determine if enough habitat exists to support target populations of waterfowl throughout winter. I estimated waterfowl food abundance at 14 coastal freshwater marsh sites in Texas and Louisiana from August 2001 to March 2003, and tested the hypothesis that wintering waterfowl reduce food abundance. I analyzed 210 and 360 seed and SAV samples, respectively, taken during September 2001, February 2002, September 2002, and February 2003 to …

Jazz And The Cultural Transformation Of America In The 1920s, Courtney Patterson Carney

LSU Doctoral Dissertations

In the early twentieth century jazz was a regionally based, racially defined dance music that featured solo and collective improvisation. Originating in New Orleans, jazz soon spread throughout the country as musicians left the South for better opportunities-both economic and social-elsewhere in the country. Jazz greatly increased in popularity during the 1920s. No longer a regional music dominated by African Americans, jazz in the 1920s helped define a generation torn between the Victorian society of nineteenth century America and the culture of modernity that was quickly defining the early twentieth century. Jazz and its eventual popularity represented the cultural tensions …

Tax Policy And Global Warming, David G. Duff

All Faculty Publications

The Canadian government announced its ratification of the Kyoto Protocol to the United Nations Framework Convention on Climate Change on December 17, 2002. Under this protocol, Canada has agreed to reduce annual emissions of greenhouse gases (GHGs) to 6 percent below 1990 levels during the period 2008-2012 - a commitment that requires a 30 percent reduction relative to projected GHG emissions for 2010 assuming business as usual. In order to achieve this objective, the Canadian government has established specific reduction targets and proposed various policy instruments in its climate change action plan (CCAP) released in November 2002. Although the main …

Barriers To Participation In Educational Programs As Perceived By First-Time Enrolling Freshmen In Higher Education, Julie Cason Mcdonald

LSU Doctoral Dissertations

Institutions of higher education face exceptional challenges in today’s environment. College costs are increasing, funding is decreasing and/or limited, public confidence is diminishing, the work-place is changing, and a shrinking pool of traditional-age college students exists. This creates an environment where colleges and universities find themselves competing for students. So that these institutions of higher education may better understand how to recruit, advise, and retain students, one must consider the barriers first-time freshmen encounter in the pursuit of formal learning as they enter college. The purpose of this study, therefore, was to determine the perceived barriers to educational participation held …

Bathroom Issues, Craig Edward Clifford

LSU Master's Theses

"Obscenity is a human manifestation. The toilet has no central nervous system. No level of consciousness. It is not aware; it is a dumb toilet; it cannot be obscene; it's impossible." Lenny Bruce How to Talk Dirty and Influence People Things that make people uncomfortable intrigue me and I find that these same things are very ones that make us laugh the hardest. The fact that sex and bodily functions both make people laugh in addition to making them feel uncomfortable is no accident.

LSU Master's Theses

Re-construction/renovation/preservation and maintenance of historic or architecturally significant buildings is one of the most difficult tasks undertaken in the public sector market place by design professionals and constructors today. Wide variations exist in the level of knowledge, training, experience and expertise of all of the parties in such an endeavor, and all projects are different. One of the most underutilized and misunderstood roles in this environment is that the professional historic preservation consultant. This thesis attempts to illustrate the efficient and beneficial role of this specialist. Included are case studies for a 1939 fraternity house on the campus of LSU, …

A Multilevel Discontinuous Galerkin Method, Jay Gopalakrishnan, Guido Kanschat

Mathematics and Statistics Faculty Publications and Presentations

A variable V-cycle preconditioner for an interior penalty finite element discretization for elliptic problems is presented. An analysis under a mild regularity assumption shows that the preconditioner is uniform. The interior penalty method is then combined with a discontinuous Galerkin scheme to arrive at a discretization scheme for an advection-diffusion problem, for which an error estimate is proved. A multigrid algorithm for this method is presented, and numerical experiments indicating its robustness with respect to diffusion coefficient are reported.

A Schwarz Preconditioner For A Hybridized Mixed Method, Jay Gopalakrishnan

Mathematics and Statistics Faculty Publications and Presentations

In this paper, we provide a Schwarz preconditioner for the hybridized versions of the Raviart-Thomas and Brezzi-Douglas-Marini mixed methods. The preconditioner is for the linear equation for Lagrange multipliers arrived at by eliminating the ux as well as the primal variable. We also prove a condition number estimate for this equation when no preconditioner is used. Although preconditioners for the lowest order case of the Raviart-Thomas method have been constructed previously by exploiting its connection with a nonconforming method, our approach is different, in that we use a new variational characterization of the Lagrange multiplier equation. This allows us to …

As The Ravens Watch: Exploring The Oracle, Kathryn Lavender Hunter

LSU Master's Theses

I believe in the process in which the artist never works alone but always in collaboration with the elements of chance. As an artist I live and work everyday collaborating with chance, from reading my cards to creating ethereal birds. As I sew pieces together, the thread becomes another element of the image by chance, stitches to lines, lines to pattern. Chance leads the birds to portraying their own personality as they are each created, one’s head tilts to the right while another sits tall with dignity. This work is about the connection to the subconscious, my connection to it …

Who Helps In A Crisis: Differentiating Among Adult Children As Sources Of Support For Their Caregiving Mothers, Michael J. Patterson

LSU Master's Theses

This thesis uses a combination of quantitative and qualitative data collected from 134 mothers about their relationships with 381 adult children during the first few months after the mothers began caring for a spouse or older parent. Building on a framework that draws on theories of social structural similarity, I anticipated that adult children who shared more social statuses with their parents would be more likely to be sources of emotional and instrumental support and less likely to be sources of interpersonal stress to their caregiving mothers. Multivariate analyses revealed no effects of structural similarity and few effects of other …

Contraflow Evacuation On The Westbound I-10 Out Of The City Of New Orleans, Gregoris Theodoulou

LSU Master's Theses

In this study, CORSIM 5.0 simulation model results were used to evaluate the effectiveness of the contraflow segment on westbound I-10 out of the City of New Orleans. The Louisiana State Police plan for the contraflow segment was used to construct the CORSIM network. Alternative plans were also developed in this study to compare the effectiveness of the contraflow operation. With the use of CORSIM, traffic flow on the contraflow segment was determined based on the amount of evacuating vehicles leaving the exit nodes. In addition the time and speed to travel the contraflow segment was estimated. The results showed …

Influences On State-Level Policies For Wildfire Risk Reduction, Marios Anastasis Valiantis

LSU Master's Theses

Wildland fires are part of the United State’s history and culture. The human dimension of State wildland fire management, - the relationship of people and wildland fire in America- is an important and driving force in how federal and state agencies respond to wildland fire, now and in the future. In many ways, the critical element for the management of wildland fire is the management of people, communities, and organizations. Explosive growth in the wildland-urban interface puts entire communities, their associated infrastructure and the socioeconomic fabric that holds communities together at a high risk from wildland fire. Year after year …

Tensile Strength And Bonding Characteristics Of Self-Compacting Concrete, Cristian Druta

LSU Master's Theses

Self-compacting concrete, also referred to as self-consolidating concrete, is able to flow and consolidate under its own weight and is deaerated almost completely while flowing in the formwork. It is cohesive enough to fill the spaces of almost any size and shape without segregation or bleeding. This makes SCC particularly useful wherever placing is difficult, such as in heavily-reinforced concrete members or in complicated workforms. The objectives of this research were to compare the Splitting Tensile Strength and Compressive Strength values of self-compacting and normal concrete specimens and to examine the bonding between the coarse aggregate and the cement paste …

"Argument Is War"-Or Is It A Game Of Chess? : Multiple Meanings In The Analysis Of Implicit Metaphors, L. David Ritchie

Communication Faculty Publications and Presentations

Both Lakoff and Johnson (1980) and Vervaeke and Kennedy (1996), in their critique of Lakoff and Johnson, drew narrowly from a broad range of reasonable interpretations of the metaphors they analyzed. Expanding the interpretations vitiates many of Vervaeke and Kennedy's criticisms, but it supports their call for an open interpretation of groups of metaphors and points toward a more complex elaboration of the theories put forth by Lakoff and Johnson. The results of applying this approach to "ARGUMENT IS WAR" suggest that war is not necessarily the primary conceptual metaphor for contentious argument, as Lakoff and Johnson claimed. Rather, there …

Census 2000: The Latino Population And The Transformation Of Metropolitan New York, Laird W. Bergad

Center for Latin American, Caribbean, and Latino Studies
