Artificial Gravity Partially Protects Space-Induced Neurological Deficits In Drosophila Melanogaster, Amber M. Paul, Siddhita D. Mhatre, Janani Iyer, Juli Petereit, Roberta M. Dolling-Boreham

Publications

Spaceflight poses risks to the central nervous system (CNS), and understanding neurological responses is important for future missions. We report CNS changes in Drosophila aboard the International Space Station in response to spaceflight microgravity (SFmg) and artificially simulated Earth gravity (SF1g) via inflight centrifugation as a countermeasure. While inflight behavioral analyses of SFmg exhibit increased activity, postflight analysis displays significant climbing defects, highlighting the sensitivity of behavior to altered gravity. Multiomics analysis shows alterations in metabolic, oxidative stress and synaptic transmission pathways in both SFmg and SF1g; however, neurological changes immediately postflight, including neuronal loss, glial cell count alterations, oxidative …


A Qualitative Descriptive Study On Re-Assessing The Mental Certification By Faa For Future Pilots, Kaung Z. Min Sep 2022

A Qualitative Descriptive Study On Re-Assessing The Mental Certification By Faa For Future Pilots, Kaung Z. Min

Student Works

Mental illness becomes one of the main problems that most pilots do not usually address. It is not because pilots do not have the courage or are open enough to talk with someone, but because the Federal Aviation Administration (FAA) forces them to hide from mental depression. Most of the time, the pilots are not willing to declare such illnesses as they fear losing their job; simultaneously, the Federal Aviation Agencies across the world require pilots to be in peat health, including their mental condition, to operate the aircraft. While it can be said that the passengers’ and crews’ safety …

Finite element models can predict subject-specific chondrolabral stresses and help to elucidate the effect of under-coverage and incongruency of the hip joint in patients with dysplasia. However, complex stress patterns are difficult to generalize and evaluate statistically. With an established correspondence across shapes from statistical shape modeling (SSM), statistical parametric mapping (SPM) allows for evaluation of local variability while preserving model subject-specificity. Herein, we evaluated the combined application of SSM and SPM to compare cartilage contact stress between control subjects and patients with dysplasia.

Previously published hip joint contact stresses were mapped onto chondrolabral surface meshes and incorporated into an …

Developmental dysplasia of the hip (DDH) is described as under-coverage of the femoral head by the acetabulum, resulting in mechanical instability. Though DDH is often diagnosed using plain film radiographs, these images cannot adequately capture 3D joint coverage. Herein, we applied a 3D statistical shape model (SSM) to the femur and hemi-pelvis of patients with DDH to objectively measure shape variation and evaluated whether SSM outputs could predict measurements of joint coverage.

The femur and hemi-pelvis were semi-automatically segmented from CT images (83 hips from 47 females with DDH). Surfaces of each hip were reconstructed from segmentations, aligned, and input …

A Patient Risk Minimization Model For Post-Disaster Medical Delivery Using Unmanned Aircraft Systems, Mark J. Simpson

Doctoral Dissertations and Master's Theses

The purpose of this research was to develop a novel routing model for delivery of medical supplies using unmanned aircraft systems, improving existing vehicle routing models by using patient risk as the primary minimization variable.

The vehicle routing problem is a subset of operational research that utilizes mathematical models to identify the most efficient route between sets of points. Routing studies using unmanned aircraft systems frequently minimize time, distance, or cost as the primary objective and are powerful decision-making tools for routine delivery operations. However, the fields of emergency triage and disaster response are focused on identifying patient injury severity …


Behavioral Intention Factors For Prescription Deliveries By Small Unmanned Aircraft In Rural Communities, Sarah M. Talley Jul 2022

Behavioral Intention Factors For Prescription Deliveries By Small Unmanned Aircraft In Rural Communities, Sarah M. Talley

Doctoral Dissertations and Master's Theses

Nearly half of the U.S. population regularly use and depend on prescription medications; however, pharmacy availability and access to pharmacy services are often lacking, particularly in rural communities. In an effort to meet local healthcare needs, delivery by sUAS is proposed to ensure the nearly 60 million rural residents have access to their prescription medications.

As an emerging technology with little research into home delivery applications, the successful implementation of sUAS for prescription medication delivery requires public acceptance and positive behavioral intention toward its use. At the time of the current research, no prior studies have specifically focused on the …


Ems To Trauma Care Transitions: An Investigation Of Patient And Handoff Outcomes, Richard Simonson Jun 2022

Ems To Trauma Care Transitions: An Investigation Of Patient And Handoff Outcomes, Richard Simonson

Doctoral Dissertations and Master's Theses

The helicopter as a method of emergency medical service transportation of trauma patients has a long history of effective use-cases dating back to its inception during the Vietnam war. Compared to ground-based emergency medical transit, helicopters have been able to reach severely injured patients in environments with challenging terrain features that ground-based medical services cannot traverse. Additionally, the helicopter offers quicker and more direct-route transit options that result in both quicker response and shorter transportation times compared to their ground-based alternative. Further, research has indicated that helicopter ambulance teams utilize paramedics with more experience than ground ambulance paramedics. Prior research …

A Meshless Approach To Computational Pharmacokinetics, Anthony Matthew Khoury

Doctoral Dissertations and Master's Theses

The meshless method is an incredibly powerful technique for solving a variety of problems with unparalleled accuracy and efficiency. The pharmacokinetic problem of transdermal drug delivery (TDDD) is one such topic and is of significant complexity. The locally collocated meshless method (LCMM) is developed in solution to this topic. First, the meshless method is formulated to model this transport phenomenon and is then validated against an analytical solution of a pharmacokinetic problem set, to demonstrate this accuracy and efficiency. The analytical solution provides a locus by which convergence behavior are evaluated, demonstrating the super convergence of the locally collocated meshless …

Stroboscopic Augmented Reality As An Approach To Mitigate Gravitational Transition Effects During Interplanetary Spaceflight, Ethan Waisberg, Joshua Ong, Nasif Zaman, Sharif Amit Kamran, Andrew G. Lee, Alireza Tavakkoli

International Journal of Aviation, Aeronautics, and Aerospace

During interplanetary spaceflight, periods of extreme gravitational transitions will occur such as transitions between hypergravity, hypogravity, and microgravity. Following gravitational transitions, rapid sensorimotor adaptation or maladaptation may occur which can affect gaze control and weaken dynamic visual acuity in astronauts. A reduction in dynamic visual acuity during spaceflight could possibly impact or impair mission critical activities (e.g., control of extraterrestrial machinery/vehicles and other important tasks). Stroboscopic visual training is an emerging visual tool that has been terrestrially observed to enhance visual performance and perception by performing tasks under conditions of intermittent vision. This technique has also been seen to increase …

Modelling Air Quality In An Aircraft Passenger Cabin Using Health Care Standards, Bert Silich Jan 2022

Modelling Air Quality In An Aircraft Passenger Cabin Using Health Care Standards, Bert Silich

International Journal of Aviation, Aeronautics, and Aerospace

The interest in aerosol contamination of aircraft passenger cabins has increased since the onset of the COVID-19 pandemic. Mathematical models have been developed to help describe how an aerosol behaves in a closed space. The number of infectious particles inhaled is of scientific interest because it can be related to the risk of getting ill from a pathogen. The data required to calculate these results is often difficult to obtain in real world settings. In fact, particle inhalation details are not obtained in the day-to-day routine of a health care environment and are they not required to maintain safety. Hospital …


Fatigue In Aircraft Maintenance Technician Schools, Natalie Zimmermann, Peng Hao Wang, Keegan Pullen Jan 2022

Fatigue In Aircraft Maintenance Technician Schools, Natalie Zimmermann, Peng Hao Wang, Keegan Pullen

International Journal of Aviation, Aeronautics, and Aerospace

Fatigue has long been identified as a human factor in aviation. Subsequently, a series of studies have highlighted fatigue-related elements within the context of the aviation industry, focusing on the flight deck – with some extension to flight students – and aviation maintenance activities. However, the latter has not been as deeply examined as its flight crew-centered counterpart. Similarly – if not more significantly – fatigue experienced by aircraft maintenance technician (AMT) students is scarcely explored, especially in comparison to the research conducted to understand fatigue in flight schools. AMT students are subject to comparable, but not the same, experiences …
