The Effect Of Flame Structure On Soot Formation And Transport In Turbulent Nonpremixed Flames Using Direct Numerical Simulation, David O. Lignell, Jacqueline H. Chen, Philip J. Smith, Tianfeng Lu, Chung K. Law Aug 2007

The Effect Of Flame Structure On Soot Formation And Transport In Turbulent Nonpremixed Flames Using Direct Numerical Simulation, David O. Lignell, Jacqueline H. Chen, Philip J. Smith, Tianfeng Lu, Chung K. Law

Faculty Publications

Direct numerical simulations of a two-dimensional, nonpremixed, sooting ethylene flame are performed to examine the effects of soot–flame interactions and transport in an unsteady configuration. A 15-step, 19-species (with 10 quasi-steady species) chemical mechanism was used for gas chemistry, with a two-moment, four-step, semiempirical soot model. Flame curvature is shown to result in flames that move, relative to the fluid, either toward or away from rich soot formation regions, resulting in soot being essentially convected into or away from the flame. This relative motion of flame and soot results in a wide spread of soot in the mixture fraction coordinate. …

Validity And Reliability Of Dynamic Virtual Interactive Design Methodology, Renran Tian Aug 2007

Validity And Reliability Of Dynamic Virtual Interactive Design Methodology, Renran Tian

Theses and Dissertations

This study focuses on testing the validity and reliability of dynamic Virtual Interactive Design (VID) methodology with dynamic ergonomics analysis. Virtual Interactive Design methodology has been introduced and applied on practical problems in several previous studies, and initially validated with posture-based static ergonomics analysis tools. Although most results have proved the validity and reliability based on static information considered, such validation processes is not sufficient since risks for performing certain tasks can not be fully examined without examining dynamic aspects. But the dynamic virtual interactive design environment has not been validated sufficiently. In my subsequent study, a dynamic ergonomics analysis …

Egocentric Depth Perception In Optical See-Through Augmented Reality, James Adam Jones Aug 2007

Egocentric Depth Perception In Optical See-Through Augmented Reality, James Adam Jones

Theses and Dissertations

Augmented Reality (AR) is a method of mixing computer-generated graphics with real-world environments. In AR, observers retain the ability to see their physical surroundings while additional (augmented) information is depicted as simulated graphical objects matched to the real-world view. In the following experiments, optical see-through head-mounted displays (HMDs) were used to present observers with both Augmented and Virtual Reality environments. Observers were presented with varied real, virtual, and combined stimuli with and without the addition of motion parallax. The apparent locations of the stimuli were then measured using quantitative methods of egocentric depth judgment. The data collected from these experiments …

The Effect Of Pasteurization Temperature On Consumer Acceptability, Sensory Characteristics, Volatile Compound Composition, And Shelf-Life Of Fluid Milk, April Lynne Gandy Aug 2007

The Effect Of Pasteurization Temperature On Consumer Acceptability, Sensory Characteristics, Volatile Compound Composition, And Shelf-Life Of Fluid Milk, April Lynne Gandy

Theses and Dissertations

The relationship among consumer acceptability, descriptive sensory attributes, and shelf-life was determined for 2 % milk pasteurized at 77, 79, 82, or 85?aC. Pasteurization temperature had no effect (p>0.05) on shelf-life. Consumers preferred (p<0.05) 79?aC over other treatments on day 0; however, six days post-pasteurization 79?aC milk was only preferred (p<0.05) over 77?aC. Consumers were grouped into eight clusters based on product liking for both day 0 and 6 evaluations. The largest cluster liked all pasteurization treatments, and 79?aC was highly acceptable to all consumers that liked milk. Similar sensory descriptors indicated the end of shelf-life for all pasteurization treatments even though treatments could be differentiated by descriptors on day 0. This research reveals that altering pasteurization temperature from 79?aC may cause a decrease in consumer acceptability to some consumers. Altering pasteurization temperature does not affect shelf-life or sensory descriptors and volatile compound profiles at the end of shelf-life.

The Implementation Of Drug Court Progams In Selected States: An Examination Of Government Influence, Lisa Ann Nored Aug 2007

The Implementation Of Drug Court Progams In Selected States: An Examination Of Government Influence, Lisa Ann Nored

Theses and Dissertations

With the merger of judicial supervision and mandated treatment, drug courts have given rise to therapeutic jurisprudence and attempt to address those issues which have plagued corrections policymakers for several decades. The evaluation literature indicates that drug courts tend to produce lower recidivism rates, increased retention rates and lower costs when compared to traditional programs. However, as drug courts approach their second decade, there is a void in the literature regarding the implementation of drug court programs. This study specifically examined those factors which either facilitate or challenge the implementation of drug court programs. This study examined implementation issues from …

The Influence Of Probiotic Lactobacilli On Glucose Uptake By Caco-2 Cells, Arun Kumar Rooj Aug 2007

The Influence Of Probiotic Lactobacilli On Glucose Uptake By Caco-2 Cells, Arun Kumar Rooj

Theses and Dissertations

The resident microbes of human gastrointestinal tract cause both harmful and beneficial effects and these effects can be modulated by the administration of beneficial probiotic bacteria. Probiotics attribute several therapeutic and preventive beneficial effects, for both humans and animals. Despite the good effects of probiotic bacteria, the role of probiotic bacteria or their metabolites on the nutrient uptake by enterocytes is very less known. Most studies describe the genomic effects of probiotic bacteria on the transport properties. This thesis describes the short term (10 min or less) non-genomic effects of probiotic bacteria on the glucose uptake by human enterocytes like …

The Role Of A Non-Microtubule-Based Spindle Matrix In Eukaryotic Cellular Division, Melissa Gwen Chambers Aug 2007

The Role Of A Non-Microtubule-Based Spindle Matrix In Eukaryotic Cellular Division, Melissa Gwen Chambers

Theses and Dissertations

A non-microtubule-based spindle matrix has been observed in Drosophila melanogaster meiotic and somatic cells. This matrix comprises the proteins: Skeletor, Megator and Chromator, which localize to the nuclear periphery and chromosomes at prophase and to the microtubule spindle during mitosis and meiosis. This matrix might play a role in nuclear organization and microtubule assembly and stabilization. It is important to determine the presence or absence of this matrix in other species in order to compare form and function to that in Drosophila. These matrix proteins were studied in both normally dividing cells and cells in which division was disrupted. Our …

Understanding The Nifm Dependence Of Nifh In Azotobacter Vinelandii: Functional Substitution Of Nifh By A Nifh-Chll Chimeric Construct In A Nifm- Strain, Kelvin Harris Jr

Theses and Dissertations

The enzyme nitrogenase catalyzes the energy-dependent reduction of dinitrogen to ammonia via biological nitrogen fixation. Nitrogenase is composed of two metalloproteins known as the molybdenum-iron (MoFe) protein and the iron (Fe) protein. The Fe protein, a 60-kDa dimer of the product of the nifH gene, contains a single 4Fe-4S cluster and two Mg-ATP-binding sites, one at each subunit. The Fe protein is the obligate electron donor to the MoFe protein. To date, no other mutual protein has shown to substitute Fe protein in biological fixation, and the NifH is functional only in the presence of the nifessory protein NifM. Interestingly, …

The Ecology And Morphological Variation Of Opuntia (Cactaceae) Species In The Mid-South, United States, Lucas C. Majure Aug 2007

The Ecology And Morphological Variation Of Opuntia (Cactaceae) Species In The Mid-South, United States, Lucas C. Majure

Theses and Dissertations

Opuntia species have been poorly studied ecologically and taxonomically in the eastern United States. This study deals with the ecology of Opuntia species in the mid-south United States and covers not only the high degree of morphological variation exhibited by taxa, but also the taxonomy and distributions of the group for Mississippi. The taxa in the mid-south have distinct habitat preferences and can be separated based on habitat characterization. Information from this work provides valuable data useful in predicting possible routes that an invasive species, Cactoblastis cactorum (the cactus moth), might use in its potential westward migration. Phenotypic plasticity exhibited …

An Analysis Of The Keetch-Byram Drought Index As A Predictor Of Forest Fire Potential, John Andrew Morris

Theses and Dissertations

Forestry management relies on combating the challenges posed by fire. Knowledge of fire risk helps in the planning for and reacting to forest fires. One method used is the mapping of the Keetch-Byram Drought Index (KBDI). Though it was not specifically designed to be a fire risk assessment tool it is used to highlight areas with a high potential of fire due to climactic factors. A statistical analysis is performed to determine the relevance of the use of this drought index to measure fire potential. Analysis is performed by testing the relationship of KBDI to the number of fires and …

Continuous Simulation Of Groundwater Use And Effluent Discharge In Catfish (Ictalurus Punctatus) Ponds At Five Locations In The Southeast U.S, Sugeng Triyono Aug 2007

Continuous Simulation Of Groundwater Use And Effluent Discharge In Catfish (Ictalurus Punctatus) Ponds At Five Locations In The Southeast U.S, Sugeng Triyono

Theses and Dissertations

Long-term climatological data were used to evaluate the effectiveness of a drop/add management strategy to reduce groundwater use and effluent discharge in catfish ponds in the southeast U.S.. A drop/add approach is based on the creation of a storage volume in the pond for rainfall collection. The storage volume is created by allowing water level in the pond to decrease until some minimum level is reached. When the minimum level is reached, the pond is partly refilled, leaving the remaining volume available to capture incident precipitation. In this way, the role of precipitation in the water budget is increased. In …

Sexual Harassment Of Women In The United States Military: Juror Decisions Of Reserve Officer Training Corps (Rotc) And Civilian College Students, Catherine Michelle Snell Aug 2007

Sexual Harassment Of Women In The United States Military: Juror Decisions Of Reserve Officer Training Corps (Rotc) And Civilian College Students, Catherine Michelle Snell

Theses and Dissertations

The present research examined the influence of military status, organizational climate type, gender, and attitudes toward sexual harassment on juror decisions in a sexual harassment trial. Military participants rated themselves as having more stereotypical masculine characteristics and they rated sexual harassment allegations more seriously. The permissive climate type elicited less serious allegation ratings. Females rated all climates as more permissive, found the defendant more liable, and chose more severe punishments. Tolerant attitudes toward sexual harassment predicted juror decisions for both ROTC and civilian mock jurors. The results highlight the need for further education about sexual harassment to reduce tolerant attitudes …

Tafoni Caves In Quaternary Carbonate Eolianites: Examples From The Bahamas, Athena Marie Owen Aug 2007

Tafoni Caves In Quaternary Carbonate Eolianites: Examples From The Bahamas, Athena Marie Owen

Theses and Dissertations

Tafoni have been confusingly defined in many ways: variations in size, rock type, and forming mechanisms. This study addresses tafoni in Quaternary eolian carbonates to help better define the term. Large tafoni were differentiated from other coastal caves in the Bahamas, specifically flank margin and sea caves, using morphometric analyses. The differentiation is important as all three cave types form in the same area, but flank margin and sea caves can be used as paleo-sea level indicators, while tafoni cannot. Small tafoni show a growth rate of 0.022 m3/yr; and may amalgmate to form larger tafoni, which grew at 0.65 …
