Effect Of Breathing, Posture, And Air Velocity On Breathing Zone Gas Concentrations For Human Subjects In A Wind Tunnel, Ahmed R. El-Sotouhy
Graduate Theses, Dissertations, and Problem Reports (ETD)
Industrial hygienists generally place air-sampling probes on the mid to upper torso of workers when attempting to determine inhaled concentrations. There is no convincing evidence that concentrations measured on the chest are equal to inhaled concentrations. To determine how well surrogate locations matched concentrations at the mouth (Cmouth), low concentrations of ethanol in nitrogen were released between the hands of standing and seated human subjects while they moved children's blocks back and forth over the source.;In all cases, each of four subjects stood or sat with their backs to the airflow in a wind tunnel because previous studies had established …

The cyclization precursors are readily prepared from commercially available compounds by a variety of methods. In addition, the first total synthesis of ht-13-A has been studied. The key steps of the synthesis are a Mitsunobu reaction, an intramolecular Heck reaction, and a reductive N-heteroannulation.
Development Of A Micro-Depth Sensing Indentation Technique With Constant Load Control, Ailing Lin
Development Of A Micro-Depth Sensing Indentation Technique With Constant Load Control, Ailing Lin
Graduate Theses, Dissertations, and Problem Reports (ETD)
In material nano- and micro-indentation research, Young's modulus can be obtained based on the initial unloading stiffness of the load-depth curve. The accurate load and displacement measurement as well as high precision position control of the indenter are needed to achieve the required measurement resolution. The application of PZT actuator is often used to perform the indentation experiment. However, conventional PZT controllers can only provide displacement control. Furthermore, each PZT actuator only serves a specific PZT controller using its unique calibration factor. Thus, it is beneficial to develop a controller, which can carry out both load and displacement control algorithm, …
*Validation Of The Assessment Of Depression Inventory (Adi) Feigning Scale And Clinical, Demographic, And Criminal Profile Differences Between Probable Malingerers And Psychiatric Inpatients, Julia Marie Messer
Graduate Theses, Dissertations, and Problem Reports (ETD)
Using archival data, "gold standard" assessment measures were used to determine group placement of psychiatric inpatients. One of two multi-scale measures of personality, the Minnesota Multiphasic Personality Inventory II (MMPI-2) or the Personality Assessment Inventory (PAI), were administered, as well as one of two interview measures designed specifically to assess for malingering, the Structured Interview of Reported Symptoms (SIRS) and/or the Miller Forensic Assessment of Symptoms Test (M-FAST). Based on either the MMPI-2 or the PAI and the SIRS, subjects were placed into one of three groups: non-malingering inpatients, probable malingerers, and indeterminate malingerers. One purpose of identifying these groups …

Application Of Multi-Agents To Power Distribution Systems, Koushaly Nareshkumar
Graduate Theses, Dissertations, and Problem Reports (ETD)
The electric power system has become a very complicated network at present because of re-structuring and the penetration of distributed energy resources. In addition, due to increasing demand for power, issues such as transmission congestion have made the power system stressed. A single fault can lead to massive cascading effects, affecting the power supply and power quality. An overall solution for these issues can be obtained by a new artificial intelligent mechanism called the multi-agent system. A multi-agent system is a collection of agents, which senses the environmental changes and acts diligently on the environment in order to achieve its …

Development And Validation Of A Diabetes-Specific Health State Classification System And Valuation Function Based On The Multi-Attribute Theory, Murali Sundaram
Graduate Theses, Dissertations, and Problem Reports (ETD)
Preference-Based Measures of Health (PBMH) provide 'preference' or 'utility' weights that enable the calculation of quality-adjusted life years for the economic evaluations of interventions. The Diabetes Utility Index (DUI) was developed as a two-page, self-administered diabetes-specific PBMH that can replace expensive time-consuming interviews with patients to estimate their health state utilities. Inputs from theory, an existing diabetes-specific measure of quality of life, and statistical analyses were submitted to a clinical expert panel. After three rounds of pilot surveys (n1=52, n2=65, n3=111) at primary care clinics in Morgantown, WV, five attributes and severity categories for each attribute were finalized on the …

Parametric Study Of A Pulsed Vertical Jet In Cross-Flow, Guillaume Francois Bidan
LSU Master's Theses
The potential of pulsed vertical jet in cross-flow for film cooling purposes was experimentally studied and is discussed in this Thesis. A single vertical jet placed in laminar cross-flow conditions was first characterized in steady state at relatively low blowing ratios ranging from 0.150 to 0.600, using Mie scattering visualization methods and hot-wire measurements. Wavelet spectral analysis and image quantification algorithms were applied to the velocity records and averaged visualizations to obtain quantitative data on the jet characteristic frequencies, penetration and coverage. Two different regimes characterized by different structures are identified and adapted scaling variables are provided. Trends in the …
Protein Degradation In Mammalian Hibernator, Spermophilus Lateralis, Vanja Velickovska
Protein Degradation In Mammalian Hibernator, Spermophilus Lateralis, Vanja Velickovska
UNLV Retrospective Theses & Dissertations
Protein synthesis is virtually non-existent during hibernation in golden-mantled ground squirrels. In the presence of negligible protein synthesis continued protein degradation would disrupt the maintenance of homeostasis and the survival of the animal. Earlier investigation showed that ubiquitin conjugate concentrations increase 2-3 fold during hibernation, which would seemingly suggest an increase of protein degradation. In this study I examined protein degradation per se as a function of the temperatures experienced by the hibernator and demonstrated that protein degradation is virtually absent at low temperatures. A new method was developed to determine the rates of ubiquitylation as a function of temperature, …

Although strides recently have been made to facilitate the understanding of relational aggression and its consequences, one significant limitation has been the lack of research on long-term impact. Through a grounded theory approach, this study examines how resiliency behaviors exhibited by victims of relational aggression during their adolescent years aid in the development of trusting adult friendships.
Ayp Accountability Policy And Assessment Theory Conflicts, Randall S. Davies
Ayp Accountability Policy And Assessment Theory Conflicts, Randall S. Davies
Mid-Western Educational Researcher
A major objective of NCLB is to hold schools accountable for student achievement including closing the achievement gap and raising standards of student academic proficiency. While the majority of individuals support the underlying values of NCLB, not all agree its accountability policy is reasonable. The most problematic issue is the mandate that schools be held accountable to ensure all students perform at grade level when the methods used by states to determine grade level proficiency preclude the attainment of this standard. The unintended consequences of a policy that does not align theoretically with established educational best practice inevitably result in …
Sheltering Corporate Assets From Political Extraction, Lorenzo Caprio, Mara Faccio, John J. Mcconnell
Sheltering Corporate Assets From Political Extraction, Lorenzo Caprio, Mara Faccio, John J. Mcconnell
Purdue CIBER Working Papers
We hypothesize that firms structure their asset holdings so as to shelter assets from extraction by politicians and bureaucrats. Specifically, in countries where the threat of political extraction is higher, we hypothesize that firms will hold a lower fraction of their assets in liquid form. Consistent with this conjecture, using firm-level data from 109 countries, we find that, across countries, corporate holdings of cash and marketable securities are negatively correlated with measures of political corruption. Further, we find that annual investment in property, plant, equipment, and inventory plus dividends is positively correlated with the measures of corruption suggesting that owners …

Visualization Of Convection Patterns Near An Evaporating Meniscus Using Micro-Piv, Pramod Chamarthy, Hemanth Dhavaleswarapu, S V. Garimella, Jayathi Y. Murthy, Steven Wereley
CTRC Research Publications
Experimental visualizations of the three dimensional (3D) convection patterns generated near an evaporating meniscus in horizontally oriented capillary tubes are presented. These patterns are caused due to the differential evaporation along the meniscus. In this study, transparent capillary tubes with refractive index close to that of the evaporating liquid were used to minimize refraction effects and obtain velocity vectors near the walls. Polystyrene fluorescent particles of 0.5 lm diameter suspended in methanol were used to make the measure- ments in tubes of 75, 200 and 400 lm diameter. For the 75 lm tube, gravity was observed to have no effect …

Evolutionary Methodology For Optimization Of Image Transforms Subject To Quantization Noise, Michael Ray Peterson
Browse all Theses and Dissertations
Lossy image compression algorithms sacrifice perfect imagereconstruction in favor of decreased storage requirements. Modelossy compression schemes, such as JPEG2000, rely upon the discrete wavelet transform (DWT) to achieve high levels of compression while minimizing the loss of information for image reconstruction. Some compression applications require higher levels of compression than those achieved through application of the DWT and entropy coding. In such lossy systems, quantization provides high compression rates at the cost of increased distortion. Unfortunately, as the amount of quantization increases, the performance of the DWT for accurate image reconstruction deteriorates. Previous research demonstrates that a genetic algorithm can …
Mechanisms Of Nickel-Based Coatings For Fretting Wear Mitigation Of Ti6al4v Interfaces, Carl H. Hager Jr.
Mechanisms Of Nickel-Based Coatings For Fretting Wear Mitigation Of Ti6al4v Interfaces, Carl H. Hager Jr.
Browse all Theses and Dissertations
Fretting wear is an accumulation of damage that occurs at component interfaces that are subjected to high contact stresses coupled with low amplitude oscillation. The key to fretting wear reduction in metallic contacts is the mitigation of galling at the interface, followed by the control of debris production and the rheology of active wear debris. Once the thin surface species of the metallic interfaces is dispersed, adhesion between the contacting nascent surfaces causes the inception of severe surface deformation and material transfer or removal. This is extremely apparent in the fretting wear of aerospace materials such as titanium alloy and …
