Preservation Of Morehead State History, Jacob Bush, Alana Scott, Dieter Ullrich

2021 Celebration of Student Scholarship - Poster Presentations

This project is being undertaken in an effort to preserve the buildings and history of Morehead State University. It is the goal of this project to make additions to the historic district of MSU by adding qualifying buildings to the National Register of Historic Places. By adding buildings to the Register, they would be recognized on the federal level as historic sites and receive support for their preservation. The Register seeks to protect sites of importance through many ways including the gifting of funding to ensure preservation. The goals of this project will be achieved using historical texts from our …

Trials And Tribulations Of Humanizing Mice For Cancer Research, Brittney Ruedlinger, Steven Warsof, Eric Feliberti, Mary Beth Hughes, Ayobami ‘Edwin’ Oshin, Chunqi Jiang, Brittany P. Lassiter, Siqi Guo, Stephen J. Beebe

The Graduate School Posters

Cancers are aggressive, evasive, and ruthless killers, claiming millions of lives every year. Cancers are heterogeneous and there is often no single, clearly defined problem as they harness and manipulate a multitude of fundamental mechanisms at the very essence of life. To investigate these mechanisms and vet potential interventive therapies, humanized mice offer a unique model as a prelude to the use of nanosecond pulse stimulation (NPS), a pulse power technology applying nanosecond duration, high electric field pulses, to ablate human tumors. Immunodeficient mouse strains, NSG and NSG-SGM3, were engrafted with human immune cells and human tumors, which would allow …

Comparison Of Three Commercial Automatic Boom Height Systems For Agricultural Sprayers, Travis A. Burgers, John D. Gaard, Brian J. Hyronimus

Mechanical Engineering Faculty Publications

Automatic boom height systems reduce the variability of agricultural sprayer boom height. Consistent boom height is important for three key reasons: to reduce uneven spray dispersion if the boom is too low, to reduce spray droplet drift if the boom is too high, and to reduce damage to the boom or crop if the boom is too low. No data is available comparing commercial boom height systems. Three leading North American automatic boom height systems were compared: John Deere BoomTrac Pro (System A), Raven AutoBoom® XRT (System B), and Norac UC5TM Passive Roll (System C) on a John Deere R4045 …

Application Of Cycle-By-Cycle Analysis To Eeg Data From Individuals With Phelan-Mcdermid Syndrome, Naomi Miller

ENGS 88 Honors Thesis (AB Students)

This study aimed to analyze a novel method of processing data from electroencephalography (EEG) recordings, which implements time-domain cycle-by-cycle analysis. This "bycycle" method, developed by the Cole & Voytek laboratory, was implemented on a EEG dataset of children with and without Phelan-McDermid Syndrome in the hopes of uncovering network-level explanations for the genetic disorder. A supplemental Python pipeline was developed to organize and visualize the data. This led to the discovery of group-level differences in measures of cycle symmetry in alpha band waves over the sensorimotor electrodes. Through the same pipeline, the bycycle tool was validated as a sound EEG …

Predictions Of Knee Joint Contact Forces Using Only Kinematic Inputs With A Recurrent Neural Network, Kaileigh Elisabeth Estler

Human Movement Studies & Special Education Theses & Dissertations

BACKGROUND: Knee joint contact (bone on bone) forces are commonly estimated using surrogate measures such as external knee adduction moments (with limited success) or musculoskeletal modeling (more successful). Despite its capabilities, modeling is not optimal for clinicians or persons with limited experience and knowledge. Therefore, the purpose of this study was to design a novel prediction method for knee joint contact forces that is equal or more accurate than modeling, yet simplistic in terms of required inputs. METHODS: This study included all six subjects’ (71.3±6.5kg, 1.7±0.1m) data from the opensource “Grand Challenge” datasets (simtk.org) and two subjects from the "CAMS" …

Moderate Heat-Assisted Gene Electrotransfer For Intradermal Dna Vaccination And Protein Replacement Therapy In The Skin, Chelsea Marie Edelblute

Biomedical Sciences Theses & Dissertations

Gene electrotransfer (GET) holds great promise for the delivery of therapeutic agents. The skin serves as an attractive target for GET due to its availability and unique cellular composition. Protein replacement therapy and DNA vaccination are potential applications for intradermal GET. The combination of moderate tissue preheating and GET has been shown to achieve elevated gene expression levels while reducing the necessary applied voltage. In the current work, we utilized a 16-pin multi-electrode array (MEA) and incorporated nine optical fibers, connected to an infrared laser, to pre-heat the tissue to 43°C before application of GET. In a guinea pig model, …

An Automated Framework For Connected Speech Evaluation Of Neurodegenerative Disease: A Case Study In Parkinson's Disease, Sai Bharadwaj Appakaya

USF Tampa Graduate Theses and Dissertations

Neurodegenerative diseases affect millions of people around the world. The progressive degeneration worsens the symptoms, heavily impacting the quality of life of the patients as well as the caregivers. Speech production is one of the physiological processes affected by neurodegenerative diseases like Alzheimer’s disease, amyotrophic lateral sclerosis (ALS) and Parkinson’s disease (PD). Speech is the most basic form of communication, and the effect of neurodegeneration degrades speech production, thereby reducing social interaction and mental well-being. PD is the second most common neurodegenerative disease affecting speech production in 90% of the diagnosed individuals. Speech analysis methods for PD in clinical methods …

Preventing Needle Stick Injuries: A Quality Improvement Project, Adrianna Kerns, Emilea Pitts, Grace Richman, Katie Rawlings, Megan Riley, Mary Suzanne White

2021 Celebration of Student Scholarship - Poster Presentations

"Needlestick injuries (NSI) affect approximately 1,000 people per day across U.S. hospitals. Needlestick injuries cost an estimated $3,042 per victim annually, according to the report. The costs go toward laboratory fees for testing exposed employees, associated labor and counseling and post-exposure follow-ups." (Beckner's Clinical Leadership & Infection Control, 2020). It was noted at an urban teaching hospital that needlestick injuries are an issue. Researchers believe this number is an underestimate of the actual amount of needle stick injuries. The purpose is to increase the education of staff nurses on the topic of needle stick injuries. We thoroughly reviewed 56 studies …

Irrigation and Melioration

The article suggests a new approach to the monetary assessment of the damage caused to the environment by the processed waste of the transport sector. The proposed assessment method is based on the waste collection factor, all types of irretrievable losses and the volume of necessary compensatory release of materials. Based on a survey among vehicle owners, it was found that the solid waste collection rate is about 50 %, while the waste collection rate for operating fluids does not exceed 32 %. In this regard, the bulk of the damage to the environment is caused by liquid waste. Calculations …

To The Determination Of The Critical Circuit Speed Of The Sharing Drum, Kh. Kh. Igamberdiev, A.B. Mukhitdinov

Irrigation and Melioration

The article is devoted to the theoretical definition of the critical circumferential speed of the stripping drum of a kena harvester, which depends on the drum diameter, diameter and weight of the stems. It was determined from the equality of the change in the momentum of the stem during impact, i.e. from a shock impulse acting on the stem. The shock impulse is determined when the drum blade touches the stem in the process of stripping, which acts on the mass of the entire stem. The duration of the impact of the drum stripping on the stem was determined from …

An Innovative Seeder For Sowing Non-Loose Seeds Of Saxaul And Cherkez, E.T. Farmonov
