Two-Dimensional Reflectivity Polarization Elastometry Imaging Techniques (Piet) Of Soft Tissue, Hee Chuan Lim

Dissertations

A non-invasive polarized light reflection measurement method to measure the stretch of soft tissue, such as skin, is described. The technique utilizes changes in the reflectivity of polarized light intensity as a monitor of skin stretch. Measurements on in-vitro pigskin and invivo human skin show that the reflectivity of polarized light intensity increases linearly with stretch over a range. The changes in diffusive reflectivity properties of skin result from the alterations that take place in the roughness across the thickness of the skin layers due to stretch. Conceptually, as the roughness of a layer decreases with stretch, a smoother reflecting …

Prenatal Maternal Attachment: The Lived Experience, Regina Ann Leva-Giroux Dnsc

Dissertations

Prenatal maternal attachment and the practice of health promoting behaviors during pregnancy are considered universal phenomena to women. Yet, the understanding of these phenomena from the lived experiences of pregnant women has not been well researched. The purpose of this phenomenological study was to describe the experience of maternal attachment to the unborn child and how that attachment might relate to the practice of these behaviors during pregnancy.

Protective Care: Mothering A Child Dependent On Parenteral Nutrition, Lorie H. Judson Phd, Mn, Rn

Dissertations

Home care of technology-dependent infants and children has become an accepted and expected consequence of higher survival rates among critically ill newborns and children who develop chronic illnesses. One of the high-tech modalities which foster dependence of these infants and children is parenteral nutrition. Parenteral nutrition, also called total parenteral nutrition (TPN), supplies life-sustaining nutrients through a central venous catheter and requires the use of machinery to pump this fluid directly into the bloodstream. Due to the tremendous cost of prolonged hospitalization for these children, and the deleterious effects to the child, home care is considered an obvious and viable …

Development Of Analytical Systems And Monitoring Of Vocs Emissions During Polymer Processing, Qin Xiang

Dissertations

A method using direct flame ionization detector (FID) measurement was developed to study total volatile organic compounds (VOCs) emissions during thermal degradation of polymers. This was used to estimate organic emissions from both virgin polymer resins and commingled plastics. The effects of process parameters, i. e., temperature, heating rate and residence time, were also studied. Significant VOCs emissions were observed at normal processing temperatures, particularly from recycled polymers. Each polymer showed a distinct evolution pattern during its thermal degradation. Kinetics of VOCs emissions were also studied using a non-isothermal technique. The kinetic parameters were in agreement with data from the …

Modeling Hydrogen Diffusion For Solar Cell Passivation And Process Optimization, Yi Zhang

Dissertations

A diffusion model for hydrogen (H) in crystalline silicon was established which takes into account the charged state conversion, junction field, mobile traps, and complex formation and dissociation at dopant and trap sites. Carrier exchange among the various charged species is a "fast" process compared to the diffusion process. A numerical method was developed to solve the densities of various charged species from the Poisson's equation that involves shallow-level dopants and one "negative U" impurity, e.g., H. Time domain implicit method was adopted in finite difference scheme to solve the fully coupled equations.

Limiting versions of the model were applied …

The Early Bronze Age Ceramic Assemblage From Tell Ta'annek, Palestine, Mark S. Ziese

Dissertations

The problem

Greenberg has recently stated that isolating temporal ceramic indicators for the Early Bronze II-III periods is "one of the thorniest issues in the archaeology of Palestine" (2000: 183). Part of theproblem stems from the homogenous nature of ceramic assemblages from Early Bronze Age Palestine; part of it stems from a continued lack of published information. Both of these issues are addressed by this study. Excavations at Tell Ta`annek between 1963 and 1967 unearthed the remains of a multi-period site, including the residues of an Early Bronze II-III fortified settlement. It is purposed here to isolate that portion of …

A Study Of The Reported Long-Term Attitudinal And Behavioral Effects Of An Eighth-Grade Environmental Education Project And The Development Of An Innovation Configuration To Promote Environmental Education, Jean Lomino

Dissertations

Problem. Increasing scientific evidence reveals that this planet is in serious environmental jeopardy. Since 1977, when an international group of K-12 educators met in the USSR and established goals for teaching environmental education worldwide, many schools have endeavored to fulfill these goals through the use of various curricula and teaching strategies. Although some progress has been made, most K-12 public schools have not done enough to meet the demands of environmental problems. In 1996, my co-teacher and I designed and implemented an environmental project, called Mission Environment, that we hoped would help our students develop long-term positive environmental attitudes …

James K. Humphrey was a Baptist minister who joined the Seventh-day Adventist Church shortly after migrating to the United States from Jamaica at the turn of the twentieth century. A leader of uncommon skill and charisma, Humphrey ministered in Harlem, New York, during the period the area became the Black capital of the United States, leading his congregation to a position of primacy in the Greater New York Conference of Seventh-day Adventists. Yet Humphrey believed that the African American experience in Adventism was one of disenfranchisement, a problem he attempted to ameliorate with the establishment of the Utopia Park Benevolent …

Women's Experiences With Chronic Heart Failure, Denise M. Boren Phd, Msn, Cns

Dissertations

Nationwide, approximately 4.1 million Americans suffer from chronic heart failure accounting for estimated direct and indirect costs of over $21 billion spent annually for health care. The incidence of heart failure has doubled each decade since the 1940's and slightly more men were inflicted with the illness. This trend changed three years ago, with a decline in the overall incidence of heart failure and a slight predominance of the illness in women rather than men. The incidence of this condition was reduced in males nearly three times that of females. Women survive longer after diagnosis, however they are hospitalized more, …

The Politicization Of Ethnicity As A Prelude To Ethnopolitical Conflict: Croatia And Serbia In Former Yugoslavia, Agneza Bozic-Roberson

Dissertations

This interdisciplinary research develops a framework or a model for the study of the politicization of ethnicity, a process that transforms peaceful ethnic conflict into violent inter-ethnic conflict. The hypothesis investigated in this study is that the ethnopolitical conflict that led to the break up of former Yugoslavia was the result of deliberate politicization of ethnicity. The model consists o f three variables— ethnic entrepreneurs as actors, and mass media and political rhetoric as their tools for politicization of ethnicity. Ethnic entrepreneurs, with a conscious interest in mobilizing ethnicity, are given this opportunity in transitional societies in which politicized ethnicity …

Fay Weldon's Late Bloomers And Comedy And A Lawyer, A Vet, And A Couple Of Dogs, One Of Them Dead, Susan Rote Siferd

Dissertations

Creative dissertation begins with a critical study of comedy as Weldon employs it in her novels of marriage, infidelity, and divorce. Traditionally, comedy ends in marriage; Weldon's dark comedies end in self-understanding as a necessary prerequisite to growth and possible future relationship. However, Weldon does not celebrate divorce. She recognizes the impact on women's lives of historic period, world events, and their own female nature. An avowed feminist, Weldon yet refuses to blame men for women's problems, but insists that while women struggle against sexism, they often conform to it. If there is no genre designation comparable to "bildungsroman" for …

The Romans Commentaries Of William Of St. Thierry And Peter Abelard: A Theological And Methodological Comparison, Steven R. Cartwright

Dissertations

In 1140, William o f St. Thierry, a Cistercian monk and former Benedictine abbot, accused Peter Abelard, the well-known philosopher and theologian, of propagating grave errors concerning Christian doctrine in his theological teachings. William’s accusations resulted in Peter’s condemnation at the Council of Sens in 1140.

This study compares the commentaries on the Episode of St. Paul to the Romans written by William of St. Thierry and Peter Abelard in the mid-1130s, only a few years before William’s accusations. While this conflict has been much studied, no one has previously examined it via these commentaries, which are the only literary …

Effect Of Relaxation On Neuro-Immune Responses Of Persons Undergoing Chemotherapy, Patricia K. Taylor Pothier Phd, Ms, Rn

Dissertations

Chemotherapy can be considered both a physiologic and a psychological stressor. Anxiety, nausea, emesis, and immunosuppression are commonly associated with chemotherapy, and may adversely affect the outcome or the process of treatment. Chemotherapy-related anxiety can exacerbate negative side-effects. Some psychological stressors, such as anxiety, can result in down-regulation of certain immune functions. Studies have demonstrated that behavioral interventions, such as specific relaxation strategies, can modify stress-related immune modulation. These behavioral interventions have also been shown to decrease the degree of nausea and vomiting associated with chemotherapy. The purpose of this study was to examine whether a relaxation intervention would result …

Volume Change Behavior Of Clay Soils And The Effect On Discrete Fractures, Heather Ann Hall

Dissertations

This study examines the behavior of subsurface fractures in fine-grained soil such as clays in response to changing environmental conditions. Fractures serve as conduits for moisture transfer, which can lead to substantial shrinking and swelling of the surrounding fracture boundary soils. These volume changes, in turn, affect fracture geometry and moisture transmission rates. A new predictive model, termed the 'Fracture Volume Change Model' (FVC Model), has been developed to relate moisture transfer, soil volume change and associated changes in fracture aperture. The model assumes a discrete horizontal fracture in a laterally-infinite, saturated, expansive clay with rigid, outer no-flow boundaries and …

A Dynamical Model Of The Distributed Interaction Of Intracellular Signals, Adrienne C.N. James

Dissertations

A major goal of modern cell biology is to understand the regulation of cell behavior in the reductive terms of all the molecular interactions. This aim is made explicit by the assertion that understanding a cell's response to stimuli requires a full inventory of details. Currently, no satisfactory explanation exists to explain why cells exhibit only a relatively small number of different behavioral modes.

In this thesis, a discrete dynamical model is developed to study interactions between certain types of signaling proteins. The model is generic and "connectionist" in nature and incorporates important concepts from the biology. The emphasis is …

An Investigation Of Centrifugal Blood-Cell Separation, Timothy Edward Roche

Dissertations

This dissertation investigated the centrifugal, batch separation of whole blood into subpopulations of red blood cells (erythrocytes) and white blood cells (leukocytes). Separations took place in a custom-built centrifuge (using a seal-less, anti-twisting feed/withdrawal system) containing, a 25-ml capacity separation chamber. The blood separation chamber had dart-shaped geometry in the radial plane and a constant depth in the axial direction. Separation experiments were performed on whole bovine blood at varying hematocrit, centrifuge speed, and batch duration. A small, companion study of whole human blood separation runs also were conducted; they concentrated on batch duration effect and achieved superior separations.

Predicting Thermodynamic And Transport Parameters For Metal Contaminant Sorption To Hydrated Metal Oxides In Aquatic Systems, Paras Trivedi

Dissertations

Hydrated oxides such as HAO,'HFO, goethite, and BA40 are prevalent in soils and sediments as discrete particles or as coatings. These microporous oxides have large surface areas and high affmity for metal ions, and hence they act as both a sink and a source for anthropogenically released metal contaminants. To better understand risks posed by metals in the environment and to develop effective waste management programs, mechanistic models are needed to accurately predict their fate in soils and sediments.

To achieve this objective, sorption of metal ions Sr, Cd, Zn, Ni, and Ca to these oxides were studied with macroscopic …
