Knights, Dudes, And Shadow Steeds: Late Victorian Culture And The Early Cycling Clubs Of New Orleans, 1881-1891, Lacar E. Musgrove

LSU New Orleans Theses and Dissertations

In the 1880s, two cycling clubs formed in New Orleans—the New Orleans Bicycle Club in 1881 and the Louisiana Cycling Club in 1887. These clubs were institutions of Victorian middle class culture that, like other athletic clubs, arose from the conditions of urban modernity and Victorian class anxieties. The NOBC, like other American cycling clubs, conformed to Victorian values of order and respectability. The attitudes and activities of the LCC, whose membership was younger, reflected instead a counter-Victorian ethos. This paper examines these two clubs in the context of late Victorian culture in New Orleans as it responded both to …

Wastewater Disinfection In Enclosed Recirculation Systems With Electromagnetic Waves, Luis G. Mosquera

LSU New Orleans Theses and Dissertations

Finding the most cost-effective and environmental friendly way to treat and disinfect wastewater has been raising concerns around the world. Failure in performing disinfection of wastewater before returning it to the environment could have terrible consequences to human health and the ecosystem. The risks associated to continue with current practices have led to the creation of stringent regulations.

In this research the HYDROPATH technology is tested while attaching a HydroFlow 60i unit to a reactor that works as a closed recirculation system. To determine the feasibility of the HydroFlow 60i unit as an alternative method to chlorine, the EPA method …

Experimental Investigation Of Mist Film Cooling And Feasibility Study Of Mist Transport In Gas Turbines, Reda M. Ragab

LSU New Orleans Theses and Dissertations

In the modern advanced gas turbines, the turbine inlet temperature may exceed 1500°C as a requirement to increase power output and thermal efficiency. Therefore, it is imperative that the blades and vanes are cooled so they can withstand these extreme temperatures. Film cooling is a cooling technique widely used in high-performance gas turbines. However, the film cooling effectiveness has almost reached plateau, resulting in a bottleneck for continuous improvement of gas turbines' efficiency.

In this study, an innovative cooling scheme, mist film cooling is investigated through experiments. A small amount of tiny water droplets with an average diameter about 10-15 …

A Study On The Integration Of A Novel Absorption Chiller Into A Microscale Combined Cooling, Heating, And Power (Micro-Cchp) System, Scott J. Richard

LSU New Orleans Theses and Dissertations

This study explores the application of micro-CCHP systems that utilize a 30 kW gas microturbine and an absorption chiller. Engineering Equation Solver (EES) is used to model a novel single-effect and double-effect water-lithium bromide absorption chiller that integrates the heat recovery unit and cooling tower of a conventional CCHP system into the chiller’s design, reducing the cost and footprint of the system. The results of the EES model are used to perform heat and material balances for the micro-CCHP systems employing the novel integrated chillers, and energy budgets for these systems are developed. While the thermal performance of existing CCHP …

A Numerical Study Of High Temperature And High Velocity Gaseous Hydrogen Flow In A Cooling Channel Of A Ntr Core, Sajan B. Singh

LSU New Orleans Theses and Dissertations

Two mathematical models (a one and a three-dimensional) were adopted to study, numerically, the thermal hydrodynamic behavior of flow inside a single cooling channel of a Nuclear Thermal Rocket (NTR) engine. The first model assumes the flow in the cooling channel to be one-dimensional, unsteady, compressible, turbulent, and subsonic. The working fluid (GH₂) is assumed to be compressible. The governing equations of the 1-D model are discretized using a second order accurate finite difference scheme. Also, a commercial CFD code is used to study the same problem. Numerical experiments, using both codes, simulated the flow and heat transfer …

We report on VERITAS observations of the BL Lac object B2 1215+30 between 2008 and 2012. During this period, the source was detected at very high energies (VHEs; E > 100 GeV) by VERITAS with a significance of 8.9σ and showed clear variability on timescales larger than months. In 2011, the source was found to be in a relatively bright state and a power-law fit to the differential photon spectrum yields a spectral index of 3.6 ± 0.4stat ± 0.3syst with an integral flux above 200 GeV of (8.0 ± 0.9stat ± 3.2syst) × 10−12 cm−2 s−1. No short term variability …

Nutrient Limitation In Three Lowland Tropical Forests In Southern China Receiving High Nitrogen Deposition: Insights From Fine Root Responses To Nutrient Additions, Feifei Zhu, Muneoki Yoh, Frank S. Gilliam, Xiankai Lu, Jiangming Mo

Biological Sciences Faculty Research

Elevated nitrogen (N) deposition to tropical forests may accelerate ecosystem phosphorus (P) limitation. This study examined responses of fine root biomass, nutrient concentrations, and acid phosphatase activity (APA) of bulk soil to five years of N and P additions in one old-growth and two younger lowland tropical forests in southern China. The old-growth forest had higher N capital than the two younger forests from long-term N accumulation. From February 2007 to July 2012, four experimental treatments were established at the following levels: Control, N-addition (150 kg N ha^–1 yr^–1), P-addition (150 kg P ha^–1 yr^{–1 …}

Toni Morrison’S Depiction Of Beauty Standards In Relation To Class, Politics Of Respectability, And Consumerism In Song Of Solomon, Karen Jensen

LSU New Orleans Theses and Dissertations

In Song of Solomon, published during a transitional moment in the history of U.S. feminism, Toni Morrison portrays the destructive forces of hegemonic female beauty standards, materialism, and consumerism in a Midwestern African-American community from the 1930s to the 1960s. She reveals a hierarchy in which men define standards of beauty and respectability that enforce white bourgeois ideals. Focusing on five female characters, this thesis examines this hierarchy; the agents who maintain it; and the ways in which it affects female characters who accept and/or reject it. While one of the characters, Hagar, perishes in her attempt to live …

Categorization Of Large Corpora Of Malicious Software, Deekshit Kura

LSU New Orleans Theses and Dissertations

Malware is computer software written by someone with mischievous or, more usually, malicious and/or criminal intent and specifically designed to damage data, hosts or networks. The variety of malware is increasing proportionally with the increase in computers and we are not aware of newly emerging malware. Tools are needed to categorize families of malware, so that analysts can compare new malware samples to ones that have been previously analyzed and determine steps to detect and prevent malware infections.

In this thesis, I developed a technique to catalog and characterize the behavior of malware, so that malware families, the level of …

Anion-Peptide Adduct Formation And Decomposition As Studied By Fourier Transform Ion Cyclotron Resonance (Ft-Icr) Mass Spectrometry, Xiaohua Liu

LSU New Orleans Theses and Dissertations

A new “best match” match model has been developed to account for adduct formation on multiply charged peptides observed in negative ion electrospray mass spectrometry. To obtain a stable adduct, the model necessitates an approximate matching of apparent gas-phase basicity (GBapp) of a given proton bearing site on the peptide with the gas-phase basicity (GB) of the anion attaching at that site. Evidence supporting the model is derived from the fact that singly charged adducts were only observed for lower GB anions: HSO₄^-, I^-, CF₃COO^-. Ions that have medium GBs (NO …

Big Five Personality Traits, Pathological Personality Traits, And Psychological Dysregulation: Predicting Aggression And Antisocial Behaviors In Detained Adolescents, Katherine S. L. Lau

LSU New Orleans Theses and Dissertations

This study tested the utility of three different models of personality, namely the social and personality model, the pathological personality traits model, and the psychological dysregulation model, in predicting overt aggression, relational aggression, and delinquency in a sample of detained boys (ages 12 to 18; M age = 15.31; SD = 1.16). Results indicated that the three personality approaches demonstrated different unique associations with aggression and delinquency. The psychological dysregulation approach, composed of behavioral dysregulation, emotional dysregulation, and cognitive dysregulation, emerged as the overall best predictor of overt aggression, relational aggression, and delinquency. After controlling for the Big Five personality …

The Effects Of Ecological Context And Individual Characteristics On Stereotyped Displays In Male Anolis Carolinensis, Catherine Policastro

LSU New Orleans Theses and Dissertations

Displays are ubiquitous throughout the animal kingdom. While many have been thoroughly documented, the factors affecting the expression of such displays are still not fully understood. We tested the hypotheses that display production would be affected by ecological context (i.e. the identity of the receiver) and intrinsic qualities of the signaler (i.e. heavyweight and lightweight size class) in the green anole lizard, Anolis carolinensis. Our results supported these predictions and show that a) ecological context, specifically displaying to conspecifics, has the greatest impact on display production; b) size class influenced display rate with heavyweight males displaying more to green …

The Interaction Of Post-Partum Depression And Maternal Knowledge Of Infant Development On Change In Sensitive And Responsive Parenting During Early Infancy, Julie Weiss

LSU New Orleans Theses and Dissertations

Sensitive and responsive parenting during early infancy is highly understudied, particularly in families with a low socioeconomic status. Longitudinal data from 41 mothers and their 4 to 16 week old infants found that accurate maternal knowledge of infant development positively affected parenting contemporaneously and over time while depression did not affect parenting in this sample. Implications for intervention and research are discussed.

Wave Transformation At A Saltmarsh Edge And Resulting Marsh Edge Erosion: Observations And Modeling, Kevin J. Trosclair

LSU New Orleans Theses and Dissertations

This study examines wind generated waves during winter storms, their transformation/attenuation near the marsh edge, and the resulting saltmarsh edge erosion. A simple numerical model for wave generation, transmission and marsh edge erosion was developed and validated against observations from Lake Borgne, Louisiana. Results suggest that meteorological conditions modify the local water depth via wind or wave setup and atmospheric pressure, thus exerting a first order control on the location of wave attack, which in turn determines the type of wave forces (shear vs. impact) that dominate the erosion process. Scarp failure follows, at a location determined by water level, …

Semantic Services For Enterprise Data Exchange, James A. Sauvinet

LSU New Orleans Theses and Dissertations

Data exchange between different information systems is a complex issue. Each system, designed for a specific purpose, is defined using a vocabulary of the specific business. While Web services allow interoperations and data communications between multiple systems, the clients of the services must understand the vocabulary of the targeting data resources to select services or to construct queries. In this thesis we explore an ontology-based approach to facilitate clients’ queries in the vocabulary of the clients’ own domain, and to automate the query processing. A governmental inter-department data query process has been used to illustrate the capability of the semantic …

A Multi-Gene By Environment Perspective Of Adhd Symptomatology In Young Children, Amber L. Allison

LSU New Orleans Theses and Dissertations

Attention deficit hyperactivity disorder (ADHD) is a heritable disorder, which has detrimental effects on childhood development and is associated with maladaptive functioning in adulthood. Despite this, we are far from an understanding of the etiology and possible trajectories of ADHD, possibly due to investigations focusing on the contribution of single genes. In fact, single genes are likely not influential enough to alter behavior, but the additive effect of many genes may predispose an individual toward certain behaviors. Further, environmental input can activate or suppress genetic expression, thereby leading to vast individual differences in both normative behavior and psychopathological illness, including …

Assessing The Responses Of Adult, Juvenile, And Larval Fish Assemblages To The Closure Of The Mississippi River Gulf Outlet, An Artificial Tidal Pass In Southeastern Louisiana, Rebecca Weatherall Cope

LSU New Orleans Theses and Dissertations

The creation of the Mississippi River Gulf Outlet (MRGO) in 1963 by the U.S. Army Corps of Engineers (USACE) represents one of the most catastrophic, anthropogenic stressors ever to impact the Lake Pontchartrain estuary in southeastern Louisiana, USA. The artificial tidal pass provided a direct route from the Gulf of Mexico to New Orleans. It allowed for high saline waters to enter Lake Pontchartrain, resulting in detrimental changes to the biotic community of the Lake and surrounding wetland areas. In July 2009, the USACE closed the MRGO in hopes of restoring natural ecosystems. This study assesses changes in the adult, …

Comment On “Synthesis, Characterization, And Structures Of Persistent Aniline Radical Cation”: It Is A Protonated Aniline And Not An Aniline Radical Cation, Marat R. Talipov, Jeewantha S. Hewage, Sergey V. Lindeman, James R. Gardinier, Rajendra Rathore

Chemistry Faculty Research and Publications

The same, but different: The reaction of tri-tert-butylaniline (TBA) with AgSbF₆ in CH₂Cl₂ produces a green-colored intermediate which undergoes decomposition to form a protonated aniline (TBAH⁺SbF₆⁻). Crystals of the protonated aniline salt (see picture) were analyzed by X-ray diffraction and found to have the same crystal characteristics as the crystals of the supposed cation radical first identified in 2012.

Modeling Reliability Growth In Accelerated Stress Testing, Jason K. Freels

Theses and Dissertations

Qualitative accelerated test methods improve system reliability by identifying and removing initial design flaws. However, schedule and cost constraints often preclude sufficient testing to generate a meaningful reliability estimate from the data obtained in these tests. In this dissertation a modified accelerated life test is proposed to assess the likelihood of attaining a reliability requirement based on tests of early system prototypes. Assuming each prototype contains an unknown number of independent competing failure modes whose respective times to occurrence are governed by a distinct Weibull law, the observed failure data from this qualitative test are shown to follow a poly-Weibull …
