Exploring The Use Of Virtual Reality In Designing And Prototyping Medical Devices, Evan Marsh
Exploring The Use Of Virtual Reality In Designing And Prototyping Medical Devices, Evan Marsh
Honors Theses
A degree in engineering is highly sought after in the United States. Despite the grueling coursework and sacrifices involved in earning an engineering degree, the rewards after college are numerous. However, the engineering field is vast, and the degree obtained is not always the profession followed in industry. A lot of what we learn in the college of engineering is very broad and surface-level. It is worth noting that only about 10% of what engineering students learn in school is applicable in the workplace, but they wish they had learned a lot more about that 10%.
A Device For Measuring Acoustic Output Intensity Of Transcranial Doppler Ultrasound Transducers For Comparison With Fda Regulations, Sarah Altman, Gregory Bashford, Benjamin Hage
A Device For Measuring Acoustic Output Intensity Of Transcranial Doppler Ultrasound Transducers For Comparison With Fda Regulations, Sarah Altman, Gregory Bashford, Benjamin Hage
Honors Theses
Transcranial Doppler Ultrasonography (TCD) is a non-invasive methodology which can evaluate cerebral blood flow velocity in real time. Single-element focused circular transducers placed on the scalp produce ultrasound waves capable of penetrating the skull with minimal aberration, enabling measurement of the Doppler shift. As such, TCD can measure blood flow velocity in the internal carotid and vertebral arteries, as well as the arteries of the Circle of Willis: the Anterior Cerebral (ACA), Posterior Cerebral (PCA), and Middle Cerebral Arteries (MCA). Intracranial aneurysm and ischemic stroke are serious conditions in which ballooning or occlusion of cerebral vessels cause insufficient perfusion, leading …
Biomechanical Analysis Of Athletes Sprinting With Varying Degrees Of Resistance, Michaela Ott
Biomechanical Analysis Of Athletes Sprinting With Varying Degrees Of Resistance, Michaela Ott
Honors Theses
Utilizing resistance methods for sprinters is a common approach to their training. In this study, six athletes from the University of Nebraska-Lincoln Women’s Track and Field Team ran a series of sprints using a resistance machine to collect data regarding the change in power output, stride length, level of trunk tilt with respect to the ground, and acceleration throughout a distance of ten meters when different amounts of resistant forces were applied to the athlete. It was hypothesized that as resistance increased, power output would increase, stride length would decrease, the runners would become more horizontal resulting in a larger …

Two-Dimensional & Three-Dimensional Microarray Cell Culture Using Elastomeric Assembly Substrates, Angel Olivera-Torres
Honors Theses
Tissue engineering and regenerative medicine represent the collection of all engineering disciplines brought together for the common goal of developing novel ways of growing tissues and organs in the laboratory. Efforts have made it possible to replicate or induce growth of 2D structures in the human body like skin, but the clinical need for on-demand solid organs has yet to be met due to lack of understanding of the variables responsible for organogenesis. Cell-colony heterogeneity, 3D-cellular architecture, bioactive molecules, and crosstalk communication between parenchymal cell populations need to be further investigated, and high-throughput technologies can rapidly increase the rate at …
Designing A Week-Long Biomedical Engineering Summer Camp To Increase Young Students’ Interest And Self-Efficacy In Stem, Kayla Ney
Honors Theses
In order to combat the negative feelings many young students have towards STEM, I designed a week-long summer camp that teaches students about biomedical engineering as well as collaboration, communication, and confidence with STEM subjects. This work includes a literature review outlining what STEM is and current issues in STEM education, including disinterest in STEM and attrition in STEM degree programs. The literature review outlines current methods and ideas being utilized to combat these issues, namely, inclusive pedagogical strategies, and how some of these concepts can be applied to the summer camp. The curriculum document included outlines each activity, its …
Generation Of Silver Nanoparticle Pharmacokinetic Profiles In A Lung Model, Rachel Galaska
Generation Of Silver Nanoparticle Pharmacokinetic Profiles In A Lung Model, Rachel Galaska
Honors Theses
Nanomaterial technologies are becoming increasingly prevalent in consumer and industrial applications, including drug delivery, energy harvesting, environmental applications, and medicine due to their unique physiochemical properties. As nanomaterial use increases, so too does human exposure. This has made it progressively more important to understand the toxicological effects of nanomaterials and their interactions with the human body. Silver nanoparticles (AgNPs) are one of the most commonly used nanomaterials due to their antibacterial properties. As inhalation is one of the most common exposure routes, understanding the toxicity of these AgNPs on lung tissue was studied. Using A549 cells for a lung tissue …
Effect Of Activated Carbon On The Performance Of A Solar Thermal Adsorptive Refrigerator (Star) Using Activated Carbon-Ethanol, Joshua Romo
Honors Theses
The Solar Thermal Adsorptive Refrigerator (STAR) project at the University of Dayton seeks to bridge sustainability and the need for reliable refrigeration in developing communities. Cost-effective construction, operation, and maintenance as well as the use of a sustainable adsorption pair, activated carbon-ethanol, give STAR great potential in the realm of humanitarian engineering. This project explores the effect of using two activated carbon brands, 8x16 and CocoPlus, on the cyclic performance of the STAR system. Although both brands have similar specifications given by the manufacturer, one (8x16) inhibited successful performance while the other (CocoPlus) enabled it. This project highlights both the …
Dynamic Classification Of Moisture Stress Using Canopy And Leaf Temperature Responses To A Step Changes Of Incident Radiation, Erin E. Stevens, George E. Meyer, Ellen T. Paparozzi
Dynamic Classification Of Moisture Stress Using Canopy And Leaf Temperature Responses To A Step Changes Of Incident Radiation, Erin E. Stevens, George E. Meyer, Ellen T. Paparozzi
Honors Theses
Environmental conditions affect plant productivity and understanding how plants respond to drought stress can be measured in different ways. This study focused on measuring leaf response time to induced water stress. Leaf response time to a step increase and step decrease in radiation was computed for four species of well-watered and water-stressed plants in a controlled environment. The canopy temperature was measured with an infrared thermometer and a thermal imaging camera. Thermal images were analyzed to determine the average temperature of a selected single, unobstructed leaf at the top of the canopy. Both the canopy response time and the single …

Chitosan Nanoparticle Modifications For Improved Gene Delivery In An Oral Dna Vaccine Application, Austin Helmink
Honors Theses
Vaccines represent one of the most significant medical innovations of the 20th century, resulting in the eradication or near eradication of a handful of deadly diseases. However, many infectious diseases remain resistant to effective vaccination, largely due to a lack full immune activation by traditional protein-based vaccines. A promising alternative vaccination strategy is the emerging development of DNA vaccines, which rely upon the delivery of exogenous genetic material to host cells encoding for a viral or bacterial antigen in order to induce a robust immune response by closely mimicking live infection. The delivery of genetic material requires a carrier …
