Dc Dielectrophoretic Assisted Anti-Fouling Filtration System, Nathan M. Cohen

Master's Theses

Filtration processes, whether on the microfluidic, clinical treatment systems, or industrial scale (e.g., point-of-care diagnostics, dialysis, and biopharmaceutical manufacturing, respectively), are often inseparable from membrane clogging (fouling). As a consequence, most, if not all, filtration systems require frequent maintenance to maintain functionality and efficiency. The thesis of this project hypothesizes that Dielectrophoresis can be combined with standard filtration to reduce filter fouling, extending membrane life, and enabling continuous operation. This project investigates a method to reduce fouling, add specificity and efficiency, and decrease the cost and challenge of filtration based biofluid separations.

To substantiate this thesis, we designed, fabricated, and …

Master's Theses

Mechanical Integration of a Versatile Air Suspension into a Powered Wheelchair

Joel Steinkraus

It is undeniable that the vibration environment created by prolonged exposure to wheelchair use can cause discomfort for the rider and put him/her at risk of developing more severe medical conditions. While more research must be done to accurately quantify what constitues a harmful vibration environment, improved vibraiton isolation is an essential step. In order to incorporate structurally sound and effetive air suspension systems into motorized wheelchairs, a support structure is necessary. An after market wheelchair suspension system was designed, modeled, built and tested. Approximately 18 inches …

Responsive Materials Via Diels-Alder Chemistry, Gregory Alan Strange

Master's Theses

The corrosion of infrastructure imposes a significant monetary cost, and at times human cost, upon society. Methods to improve corrosion resistance of materials are described herein which utilize the reversibility of the Diels-Alder reaction to impart thermal responsiveness upon materials. Such stimuli responsiveness can potentially play a role in self healing properties which lead to reduced cracking and thus increased corrosion protection.

Reversible Diels-Alder chemistry was utilized to manipulate the surface energy of glass substrates. Hydrophobic dieneophiles were prepared and attached to glass slides and capillaries to yield a nonwetting surface. Thermal treatment of the surfaces cleaved the Diels-Alder linkage, …

Bacterial Source Tracking Of E. Coli In A Constructed Wetland, Rose M. Martin

Master's Theses

Bacterial source tracking was used to identify sources of fecal contamination in a constructed wetland. Nucleotide sequence differences in the Escherichia coli malate dehydrogenase (mdh) gene were used to distinguish between strains isolated from pigeon and cattle feces. Fourteen E. coli isolates were taken from cattle and pigeon fecal samples and sixteen E. coli isolates were taken from wetland water samples. A region of the E. coli mdh gene was amplified via PCR and sequenced. Twelve distinct sequences were obtained. Water samples indicated the presence of both pigeon and cattle fecal contamination in the wetland. Six sequences distinct …

Agency Through Ambiguity: Women Ngo Workers In Jalalabad, Afghanistan, Melissa S. Kerr Chiovenda

Master's Theses

Pashtun women working for international NGOs and development organizations in Jalalabad Afghanistan balance the requirements of their employment with a set values, known as doing pashto, that guide their behavior as Pashtuns. These two influences on their lives are often contradictory. Based on fieldwork in Jalalabad, this study suggests that Pashtun women working for such organizations do not overtly resist Pashtun norms that often enforce a strict segregation of women. Rather, they use strategic ambiguity, maintaining that they are performing pashto well while at the same time taking part in some work activities that on the surface appear contrary to …

The Design And Fabrication Of A Microfluidic Reactor For Synthesis Of Cadmium Selenide Quantum Dots Using Silicon And Glass Substrates, Peter Robert Gonsalves

Master's Theses

A microfluidic reactor for synthesizing cadmium selenide (CdSe) quantum dots (QDs) was synthesized out of a silicon wafer and Pyrex glass. Microfabrication techniques were used to etch channels into the silicon wafer. Holes were wet-drilled into the Pyrex glass using a diamond-tip drill bit. The Pyrex wafer was anodically bonded to the etched silicon wafer to enclose the microfluidic reactor. Conditions for anodic bonding were created by exposing the stacked substrates to 300V at ~350oC under 5.46N of force. A syringe containing a room temperature CdSe solution was interfaced to the microfluidic reactor by using Poly (dimethylsiloxane) (PDMS) as an …

The Goldschmied Propulsor concept combines boundary layer suction and boundary layer ingestion to improve propulsive efficiency and reduce drag on an axisymmetric body. This investigation of a Goldschmied Propulsor aimed to determine influential characteristics of the suction slot geometry to aid in better slot geometry design and to decrease the suction flow requirements for maintaining attached flow over the entire model surface. The Propulsor model was 38.5 inches in length with a max diameter of 13.5 inches. Three suction slot geometries were investigated with the addition of aluminum cusps to the slot entrance. The cusps varied in the distance they …

Second Generation Data-Logging System For Long-Duration Field Measurement Of Vibration Exposure And Grip Force, Robert H. Knapp Iii

Master's Theses

Millions of United States workers are exposed to vibration at their job, whether it is from a power tool that causes hand and arm vibration or from heavy machinery. These vibrations are known to result in physical disorders such as Hand-Arm Vibration Syndrome, which can be debilitating to the point where workers can no longer do their job effectively. Research groups have taken an interest in finding what vibration characteristics are most harmful and choose to record vibration information using data-logging devices. Often, many devices, whether they are commercial or custom-built devices, use frequency weightings and full day estimations to …

Desert Hedgehog Is A Mammal-Specific Gene Expressed During Testicular And Ovarian Development In A Marsupial, William A. O'Hara

Master's Theses

Desert hedgehog (DHH) belongs to the hedgehog gene family that act as secreted intercellular signal transducers. DHH is an essential morphogen for normal testicular development and function in both mice and humans but is not present in the avian lineage. Like other hedgehog proteins, DHH signals through the patched (PTCH) receptors 1 and 2. Here we examine the expression and protein distribution of DHH, PTCH1 and PTCH2 in the developing testes of a marsupial mammal (the tammar wallaby) to determine whether DHH signalling is a conserved factor in gonadal development in all therian mammals.

Challenges And Livelihood Strategies Of Darfurian Refugees Living In Kampala, Uganda, Angela F. Lucia

Master's Theses

The phenomenon of urban refugees poses many challenges to the United Nations High Commissioner for Refugees (UNHCR), host governments, and non-governmental organizations (NGOs) that are providing services to them, thereby posing many challenges to the refugees themselves in having their needs addressed. My research with the Darfurian refugee population in Kampala, Uganda provides evidence on this relatively new Diaspora. Data was collected from June 2011 to August 2011, with the assistance of members of the Darfurian Refugee Association in Uganda (DRAU). Sixty-six respondents participated in the research, through methods including a questionnaire with open-ended questions to fifty-two refugees, fourteen semi-structured …

South Sudan & The “Global Land Grab”: Implications For The Future Of Food Security, Sarah Falltrick

Master's Theses

Abstract

More than 870 million people across the world do not have enough to eat, 98 percent of them live in developing countries. While researchers disagree on the causes of hunger, they all agree that it is a pressing concern. South Sudan occupies some of the most fertile land with access to several major water sources -- all the ingredients for a thriving agriculture sector -- and yet, it is a net food importer. Worse, 60 percent of the population does not consume enough food to provide a nutritious diet. Why does a country with all the best natural endowments …

One Sex, One School, Who Wins: How Single-Sex Learning Environments Impact Educational Attainment, Socio-Emotional Health, And Ambitions, Bradley Kirshenbaum

Master's Theses

Research on single-sex schools has covered a variety of matters regarding the effectiveness of their programs. This paper examines research on single-sex schools over the past 30 years in an effort to harmonize the past discourse with present trends. Journal articles and government research were used to synthesize the variety of methods used to ascertain whether single-sex schools have a positive influence on boys, girls, or both parties. Research trends have overwhelmingly supported all-girls schools, while remaining skeptical of any positive influence on boys. Much of the research supporting all-girls schools also suggests that single-sex schools' benefits are applicable to …

Determination Of The Molecular Mechanisms Of Hyperglycemia-Induced Changes In Cav3.2 Calcium Channel Properties, Ginny Marie Keeling

Master's Theses

Hyperglycemia can cause altered excitability due to increased CaV3.2 T-type calcium channel function, bestowing diabetics an increased neuropathy risk. The objective of this study was to understand the molecular mechanisms of increased CaV3.2 function during hyperglycemia in vitro, which leads to a 58% increase in current density and increased channel open probability (PO), among other changes. Two major findings are reported in this study:

1) The enzymatic elimination of extracellular N-acetylneuraminic acid (NANA) moieties reversed the increase in current density and the shift in PO, showing that hyper-glycosylation alters channel function in disease.

2) Treatment with GM1 (a ganglioside highly …

Treatment Compliance And Recidivism: Following Up On The 2000 Illinois Juvenile Probation Outcome Study, Connor Concannon

Master's Theses

This study examines the relationship between demographics, treatment completion, and recidivism in a cohort of Illinois juveniles discharged from probation. The current study expands on prior research through the examination of recidivism both while on supervision as well as ten years after discharge. Results indicate that while treatment completion is predictive of on-probation arrests, other factors appear to be stronger predictors of post-probation recidivism.

The analyses also provide a baseline to examine the impact of the conditions of probation prior to the implementation of substantive reforms to probation practices in Illinois in the late 1990s and early 2000s. Thus, the …

Perceived Partner Commitment And Implicit Self-Esteem Predicts Connectedness Accessibility In Response To Relationship Threat, Norma L. Reyes

Master's Theses

The current research examined the impact of perceived partner commitment, implicit self-esteem, and relationship threat on connectedness. The present study predicted that individuals with high (versus low) implicit self-esteem are more likely to access connectedness goals (on an unconscious level) after experiencing a relationship threat, when they perceive their significant others are highly committed to the relationship. This relation between implicit self-esteem and connectedness goal accessibility will not be evident in the control condition. The findings reveal perceived partner commitment moderated the relation between implicit self-esteem and relationship threat on accessing connectedness goals. However, people with high implicit self-esteem were …

Illinois Mental Health Courts: Intra-Group Dynamics In The Courtroom Work Group, Shanti J. Raman

Master's Theses

This study was intended to gain insight into key social psychological constructs in an unexplored work-group context: one premised on true team structure. Exploratory information on intra-group dynamics in Illinois mental health courts addressed levels of trust, communication, coordination, efficacy, and conflict resolution within mental health court teams.

A survey assessed how court group members associate these central variables with their teams. All reported relatively high levels of trust and team efficacy, and solid capacities for communication, coordination, and conflict resolution. No notable differences emerged in these variables relative to length of courts' operation. Team members from multiple disciplines held …

Urinary Antimicrobial Peptides And The Urinary Microbiota In A Uti-Susceptible Population Of Female Pelvic Floor Surgery Patients, Vanessa Nienhouse

Master's Theses

Urinary tract infections (UTI)s are a national priority. Women who undergo surgery for pelvic floor disorders such as pelvic organ prolapse (POP) or urinary incontinence (UI) are at increased risk for UTI, as 10-30% will contract a post-instrumentation UTI (postI-UTI) within six weeks after surgery. Currently, the factors that contribute to the high rate of postI-UTI are unknown, and there is currently no clinical assessment to identify at-risk patients. However, antimicrobial peptides (AMPs) and characteristics of the urinary microbiota have the potential to serve as biomarkers, identifying patients at UTI risk and facilitating clinical prevention studies.

While it was previously …

Binge Ethanol Leads To Decreased Macrophage Accumulation In Infected Cutaneous Wounds, Sara Hlavin

Master's Theses

Trauma patients who consumed alcohol prior to sustaining injuries have higher rates of morbidity and mortality than those with comparable injuries who did not drink. Additionally, those who drank had impaired wound healing and increased susceptibility to infection. Despite these clinical observations, few studies have explored the effect of ethanol on the innate immune cell function in a healing wound or how this may alter resolution of cutaneous infection. A murine model of ethanol and cutaneous wound infection was used to examine bacterial growth and recruitment of innate immune cells. Mice were given either ethanol (2.2 g/kg) or saline 30 …

Analyzing The Impact Of County Radon Levels And Population Size On The Allocation Of The State Indoor Radon Grant (Sirg) Funds, Stephen Douglas De Jong

Master's Theses

This thesis examines the SIRG program's effectiveness to target funds to states with the highest risk potential, based on county radon levels and population size. The primary method of determining the program's effectiveness was an analysis of the program's allocation of funds at a regional as well as a state level. The analysis focused on two of four input variables that the EPA utilizes in its regional allocation model (e.g., county radon levels and population size).

The analysis showed that the state-level allocation of funds is only marginally related to a combination of county radon levels and population size, while …

Performance Management And Performance: The Mediating Role Of Engagement, Mina Luong

Master's Theses

Organizations have been using performance management (PM) systems to improve performance and productivity. However, given the ineffectiveness of the PM systems currently in use, it has been suggested that PM systems be redesigned to make employee engagement a key determinant of performance. By adapting Gruman and Saks' (2011) engagement management model, this study examined the relationships among the factors that drive engagement, engagement, and performance. Specifically, engagement was examined as a hypothesized mediator of the relationship between the drivers of engagement (goal setting, job resources, and recognition, feedback, and fairness) and performance among employees in the healthcare industry. Results showed …

Did The Cdc Guidelines For Suicide Reports Affect The New York Times?, Joni Kathryn Marshburn

Master's Theses

The CDC informed the American media of the best way to avoid contributing to imitative suicides by releasing guidelines for suicide reports in 2001. In this study, suicide reports in the New York Times were examined to establish if these guidelines affected the reporting. To determine if there was any change, all suicide reports from five years before, the year of guideline release, and five years after were extracted from the Times database. To determine compliance, articles were coded using a coding sheet that operationalized the guidelines into 12 yes–or–no questions.

The New York Times observed nearly one and a …

Program Directors' Perceptions Of Quality In Nata-Accredited Post-Professional Athletic Training Education Programs, Joshua Pendleton

Master's Theses

The National Athletic Trainers' Association (NATA) is a member organization that oversees the health care profession of certified athletic trainers. A large body of research focused on the structure and content of curriculum for undergraduate programs has played a prominent role in the increase in their quantity and quality. Although attention has been called to graduate-level athletic-training education programs, there is currently a lack of research focused on NATA-accredited post-professional athletic training education programs (PPATEPs).

Using qualitative analysis, program directors' perceptions of quality in these NATA-accredited PPATEPs was assessed. In-depth phone interviews were conducted regarding topics such at the accreditation …
