Meaningful Measurement Matters

Ashley Martinez
Preventable and unintended consequences of medication use occur in more than 25% of ambulatory and hospitalized patients, and nearly half of long-term care patients. Unfortunately, many medications used to treat common health conditions in older adults (such as anxiety, behavioral disturbances, incontinence, insomnia, depression, and pain) have also been linked to cognitive impairment and decline. Recently, substantial efforts to investigate medications and medication classes that may be associated with cognitive impairment and decline in older...

Aggregation Behavior in the Bed Bug, Cimex lectularius L.

Paul Baker
The bed bug, Cimex lectularius L., is a common household pest that feeds on the blood of its human hosts. Unlike many other hematophagic arthropods, bed bugs have not demonstrated the ability to vector disease; yet its presence in a household often leads to fear and anxiety amongst its human host victims. Bed bugs spend the majority of their time aggregating in enclosed and hidden locations, making it difficult to detect and eradicate them. One...

Progressive Time Delay to Teach High School Students with Intellectual Disability to Initiate Manding Siri® for Unknown Information

Madelyn Calzi
A multiple probe design across participants with intermittent generalization probes was used to evaluate (a) the effectiveness of progressive time delay to teach four high school students with intellectual disability to initiate using Siri® when asked an unknown question and (b) the generalized use of Siri® when asked questions from untrained communicative partners. Technology training occurred prior to baseline to teach all participants to use Siri®. Secondary data were collected on Siri’s® response and student...

Microbial Interactions Between Compost Bedded Pack Barn Bedding and Teat Exposure in Transition Dairy Cattle

Compost bedded pack barns utilize composting methods which provide a soft surface for dairy cows to lie on. This requires optimal microbial growth, which may increase the exposure of mastitis-causing pathogens to the teats of early lactation animals. Bedding characteristics, bedding bacteria, and bacterial counts on the teat skin, teat ends, and in the milk of early lactation dairy cows housed on a compost bedded pack were assessed over a 6-month time. The main objective...

AN UNDERSTANDING OF STYLE OF BAROQUE ORNAMENTATION IN HANDEL’S OPERATIC ARIAS

Junghyun Lee
From the early 20th century to the present, new discoveries in Handel scholarship and changing ideas of Baroque performance practice have greatly affected the manner in which Handel’s operas and individual arias have been performed. Since the appearance of the first volumes of the Hallische Handel-Ausgabe in 1958, Handel’s works have experienced a renewed appreciation among performers and scholars alike, including countless opera productions. Since the introduction of the CD, many talented singers have published...

NUMERICAL APPROXIMATION OF THE GROUND REACTION AND SUPPORT REACTION CURVES FOR UNDERGROUND LIMESTONE MINES

Jesus Castillo Gomez
Pillar stability has been a matter of study for the last 70 years. The determination of pillar strength had taken different solutions and approaches over that time. This research has led to numerous empirical formulations that have reduced the number of pillar failures worldwide. However, new numerical approaches are being studied. In the last 20 years, the Ground Reaction Curve concept has been examined as a way of understanding the convergence of the rock-mass. Although...

Fabrication and Characterization of Nickel Plated Micro-resonators for Noncommutative Orientation Control in Microrobots

Marc Manheim
This thesis describes a procedure for fabricating arrays of microstructures out of SU-8 photoresist and nickel, which was developed with the goal of yielding microrobots capable of 1D rotation byway of magnetically-induced beam vibration that could be used for non-commutative orientation control. Several multi-layer geometries were designed, fabricated, tested and refined. In this process, micro-adhesion of multiple SU-8 layers was also studied. A method for depositing nickel via electroless plating was also developed, tested and...

EFFECTS OF HOLE TRANSPORTING LAYERS AND SURFACE LIGANDS ON INTERFACE ENERGETICS AND PHOTOVOLTAIC PERFORMANCE OF METHYLAMMONIUM LEAD IODIDE PEROVSKITES

So Min Park
Organic metal halide perovskites are promising materials for various optoelectronic device applications such as light emitting diodes (LED) and photovoltaic (PV) cells. Perovskite solar cells (PSCs) have shown dramatic increases in power conversion efficiency over the previous ten years, far exceeding the rate of improvement of all other PV technologies. PSCs have attracted significant attention due to their strong absorbance throughout the visible region, high charge carrier mobilities, color tunability, and ability to make ultralight...

THE COULTER PRINCIPLE

Marshall Graham
The atomic bombings of Hiroshima and Nagasaki in August 1945 made Wallace H. Coulter abruptly comprehend the critical need for rapid and accurate blood-cell counts in providing care for victims of radiation exposure. This thesis documents the unwritten story of his journey from that comprehension through his invention and implementation of the Coulter Principle, its commercialization in the first widely available automated blood-cell counter, and elaboration of that ground-breaking counter into increasingly sophisticated instrumentation for...

Divergence in Neuronal Calcium Dysregulation in Brain Aging and Animal Models of AD

Adam Ghoweri
Neuronal calcium dysregulation first garnered attention during the mid-1980’s as a key factor in brain aging, which led to the formulation of the Ca2+ hypothesis of brain aging and dementia. Indeed, many Ca2+-dependent cellular processes that change with age, including an increase in the afterhyperpolarization, a decrease in long-term potentiation, an increased susceptibility to long-term depression, and a reduction in short-term synaptic plasticity, have been identified. It was later determined that increased intracellular Ca2+ with...

ELECTRICAL AND MAGNETIC TRANSPORT PROPERTIES OF PERIODIC AND APERIODIC ARTIFICIAL SPIN ICE SYSTEMS

Justin Woods
In recent years, the topic of magnetic frustration in systems and the effect that frustration can have on system dynamics has been a rich environment for study. One such system that lends itself directly to this study are systems of single domain ferromagnetic bars in two dimensions. These ferromagnetic bars can be fabricated from a thin film using current lithography techniques. The bars are fabricated in such a way that their shape anisotropy dictates the...
