Yogurt Cultured Milk Powder As A Substitute For Yogurt Powder, Lijie Song Jan 2013

Yogurt Cultured Milk Powder As A Substitute For Yogurt Powder, Lijie Song

LSU Master's Theses

Commercial yogurt powder has to go through drying process which kills the yogurt culture, so the health benefit of the yogurt culture bacteria are lost. Also, upon reconstitution commercial yogurt powder does not taste like yogurt, it is sour and off flavored. The hypothesis of this study was that yogurt cultured milk powder would have better culture bacterial counts, better physico-chemical and sensory characteristics than commercial yogurt powder currently available. Commercial yogurt powder (CYP) was the control and yogurt cultured milk powder (YCMP) was the treatment. Freeze-dried yogurt starter culture (Lactobacillus bulgaricus and Streptococcus thermophilus at ratio 1:1) was added …

The Advertising Exposure Value Of Tyrann Mathieu To Lsu, Chad Michael Nolan

LSU Master's Theses

When LSU football players put on their uniforms and make their way on to the playing field, they become instant advertisements for Louisiana State University (LSU). When games are televised on national television, viewers are exposed to a number of different advertisements. Stadiums display corporate sponsorships and other naming rights, while television commercials serve as running advertisements. With an understanding that many aspects of the game are scripted with advertisements, this paper seeks to quantify the value of Tyrann Mathieu, a student-athlete on the LSU Football team during the 2011 football season. Though Mathieu did not receive the compensation given …

On-The-Fly Tracing For Data-Centric Computing : Parallelization, Workflow And Applications, Lei Jiang Jan 2013

On-The-Fly Tracing For Data-Centric Computing : Parallelization, Workflow And Applications, Lei Jiang

LSU Doctoral Dissertations

As data-centric computing becomes the trend in science and engineering, more and more hardware systems, as well as middleware frameworks, are emerging to handle the intensive computations associated with big data. At the programming level, it is crucial to have corresponding programming paradigms for dealing with big data. Although MapReduce is now a known programming model for data-centric computing where parallelization is completely replaced by partitioning the computing task through data, not all programs particularly those using statistical computing and data mining algorithms with interdependence can be re-factorized in such a fashion. On the other hand, many traditional automatic parallelization …

The Reduction And Reoxidation Of Ceria : A Natural Abundance Oxygen Isotope Approach, Justin Alan Hayles Jan 2013

The Reduction And Reoxidation Of Ceria : A Natural Abundance Oxygen Isotope Approach, Justin Alan Hayles

LSU Master's Theses

Ceria (CeO2) is a fluorite type oxide that has been used extensively as an oxygen storage media in three-way catalysts, as an oxygen partial pressure regulator, as a fuel additive for the reduction of soot and for the production of syn-gas from water and carbon dioxide. It is known that exposing ceria powders to low pO2 and/or high temperature conditions will cause ceria to partially reduce. This partial reduction leads to the formation of oxygen vacancies, which up to a limit, do not significantly influence the crystal structure. When partially reduced ceria is exposed to high pO2 environments, such as …

An Analysis Of Femininity : How Popular Female Characters In The Media Portray Contemporary Womanhood, Stephanie Ortego Roussell Jan 2013

An Analysis Of Femininity : How Popular Female Characters In The Media Portray Contemporary Womanhood, Stephanie Ortego Roussell

LSU Master's Theses

The impact of the media on adolescent girls has received greater theoretical, legal and societal focus over the last few decades. Several studies link the development of women’s gendered identities, healthy sexual activity and self-efficacy to how the media portray women. Restrictive or unrealistic themes of womanhood or femininity in the media can impact a young girl’s social construction of identity and provide limited examples of what it means to be a woman in today’s society. This study qualitatively examines femininity in contemporary media by analyzing—via textual analysis and focus groups—how popular female characters embody, portray and promote different conceptualizations …

Dragged Into The Future : How Interent Communications And Media Legitimacy Facilitate Lagging Gender Norms, Skylar C. Gremillion Jan 2013

Dragged Into The Future : How Interent Communications And Media Legitimacy Facilitate Lagging Gender Norms, Skylar C. Gremillion

LSU Doctoral Dissertations

Social interaction is the driving force of human society and extends far beyond one-on-one conversations – it is how we learn about the behavioral expectations, beliefs and symbols of our culture. Sometimes these beliefs and expectations are related to celebrations and events that bring cultures together. Through interaction we learn that we are expected to bring a gift to a birthday party and why we even choose to celebrate birthdays at all. Yet that same framework – which is tied to the way humans categorize each other to make interaction easier – also allows cultures to share biases about different …

A Microfluidic Bacteria Culturing Device With Maldi Mass Spectrometry Detection, Pratap Reddy Machavaram Siva Jan 2013

A Microfluidic Bacteria Culturing Device With Maldi Mass Spectrometry Detection, Pratap Reddy Machavaram Siva

LSU Master's Theses

A novel microfluidic device was developed for bacterial cell culturing using mass spectrometry as the detector. One of the challenges in proteomics is to achieve high sensitivity in the identification of proteins in complex samples with widely varying concentrations. The main limitations for proteomic studies are relatively slow and labor-intensive steps such as cell culturing and protein digestion of small sample quantities. Microfluidics is a promising approach to increase throughput and to reduce the time-consuming steps that are necessary for proteomics. When an analytical detection method is combined with microfluidics it can overcome limitations that are important in the analysis …

The Shoulder Suspension Of Bipedal Humans And The Head Suspension Of Quadrupedal Cats : A Reconstruction Of Macroevolutionary Changes Of Complex Systems Based On Nautral Experiments, Comparative Anatomy, And Biomechanical Analyses Of Extant Organisms, Michelle L. Osborn Jan 2013

The Shoulder Suspension Of Bipedal Humans And The Head Suspension Of Quadrupedal Cats : A Reconstruction Of Macroevolutionary Changes Of Complex Systems Based On Nautral Experiments, Comparative Anatomy, And Biomechanical Analyses Of Extant Organisms, Michelle L. Osborn

LSU Doctoral Dissertations

The biological processes in macroevolutionary transformations, which result in the origin of new species and supraspecific taxa, are not directly observable in organisms with long reproductive generations and need to be extrapolated and reconstructed from physiological, anatomical, and microevolutionary processes. This dissertation reconstructs the anatomical and biomechanical changes that affected the head-neck-shoulder apparatus during the macroevolutionary transformation of a quadrupedal mammal to a bipedal one by studying two model organisms, namely the human and the cat. I hypothesize that the anatomical differences in the head-neck-shoulder apparatus of the two organisms are caused by different force regimes that act on them. …

Alexandre Iacovleff : "Exotic Academicism" In Europe And America, (1914-1938), Kara Blanken Jan 2013

Alexandre Iacovleff : "Exotic Academicism" In Europe And America, (1914-1938), Kara Blanken

LSU Master's Theses

Art historians often refer to the interwar period of the early twentieth century as la retour à l’ordre. The twenty-one years from 1918 to 1939 represent a return to sober academicism, order, and classicism in art following the destruction and uncertainty caused by the First World War. This mentality of artistic “stability,” combined with the Western fascination for exotic cultures of Africa and Asia, formed the hallmarks of the Art Déco style. Alexandre Iacovleff was a Russian artist who embodied the international artistic spirit of Art Déco from 1914 until his death in 1938. His paintings and drawings, rendered in …

Peel-Off Lawyers: Legal Professionals In India's Corporate Law Firm Sector, Jayanth K. Krishnan Jan 2013

Peel-Off Lawyers: Legal Professionals In India's Corporate Law Firm Sector, Jayanth K. Krishnan

Articles by Maurer Faculty

This study is about hierarchy within the legal profession – how it presents itself, how it is retained, and how it is combated. The socio-legal literature on this subject is rich, with many roots tracing back to Professor Marc Galanter’s famous early 1970s article on the ‘Haves’ and ‘Have-Nots.’ Galanter’s piece and the work of those influenced by him rightly suggest that resources – institutional, financial, and demographic – contribute to whether lawyers are, and remain as, part of the ‘Haves.’ Yet, while resources of course greatly matter, as this study will argue other forces are significant as well.

Validation Of The Remote Food Photography Method To Quantify Intake Of Infant Formula, Abby Duhe Jan 2013

Validation Of The Remote Food Photography Method To Quantify Intake Of Infant Formula, Abby Duhe

LSU Master's Theses

Childhood obesity rates have more than tripled since the 1970s, and this increased prevalence is cause for concern as childhood obesity increases the risk of adult obesity and other comorbid diseases. Evidence suggests that the origins of obesity can be identified in infanthood. Accurate methods of assessing food intake in infants can be utilized to establish effective feeding practices in infanthood and to assess the relationship between infant feeding practices and the risk of childhood obesity. Current methods are either subjective or have limited ability for widespread use beyond clinical research settings due to cost and high burden. The aim …

Rube Tube : Cbs, Rural Sitcoms, And The Image Of The South, 1957-1971, Sara K. Eskridge

LSU Doctoral Dissertations

This dissertation examines the factors that led to the creation of the CBS rural comedy boom in the 1960s, as well as the reasons for its demise. For years, historians have dismissed the rural comedy craze as the networks catering to the growing number of southern viewers in the late 1950s. However, there were not enough to southern viewers to dictate a network’s entire programming schedule for the better part of a decade. Also, rural comedy was the domain of a single network, CBS. Had it really been a major thematic trend, all networks would have at least attempted to …

The Dimensions Of Judicial Impartiality, Charles G. Geyh Jan 2013

The Dimensions Of Judicial Impartiality, Charles G. Geyh

Articles by Maurer Faculty

Scholars have traditionally analyzed judicial impartiality piecemeal, in disconnected debates on discrete topics. As a consequence, current understandings of judicial impartiality are balkanized and muddled. This Article seeks to reconceptualize judicial impartiality comprehensively, across contexts. In an era when "we are all legal realists now," perfect impartiality-the complete absence of bias or prejudice-is at most an ideal; "impartial enough" has, of necessity, become the realistic goal. Understanding when imperfectly impartial is nonetheless impartial enough is aided by conceptualizing judicial impartiality in three distinct dimensions: a procedural dimension, in which impartiality affords parties a fair hearing; a political dimension, in which …

Aqueous Red-Emitting Silicon Nanoparticles For Cellular Imaging: Consequences Of Protecting Against Surface Passivation By Hydroxide And Water For Stable Red Emission, Sheng-Kuei Chiu, Beth Ann Manhat, William J.I. Debenedetti, Anna L. Brown, Katye Fichter, Tania Vu, Micah Eastman, Jun Jiao, Andrea Mitchell Goforth

Chemistry Faculty Publications and Presentations

Stable, aqueous, red-to-near infrared emission is critical for the use of silicon nanoparticles (Si NPs) in biological fluorescence assays, but such Si NPs have been difficult to attain. We report a synthesis and surface modification strategy that protects Si NPs and preserves red photoluminescence (PL) in water for more than 6 mo. The Si NPs were synthesized via high temperature reaction, liberated from an oxide matrix, and functionalized via hydrosilylation to yield hydrophobic particles. The hydrophobic Si NPs were phase transferred to water using the surfactant cetyltrimethylammonium bromide (CTAB) with retention of red PL. CTAB apparently serves a double role …
