Biomechanical Characterization Of Video-Recorded Short-Distance Falls Involving Children Equipped With A Biometric Device: A Pilot Study., Bret A Hilt Jan 2018

Biomechanical Characterization Of Video-Recorded Short-Distance Falls Involving Children Equipped With A Biometric Device: A Pilot Study., Bret A Hilt

Electronic Theses and Dissertations

Falls are commonly used as a false history by caregivers to conceal child abuse. Determining biomechanical compatibility is a key aspect in differentiating abuse from accident. Current forensic approaches are limited in assessing biomechanical compatibility of short-distance falls involving children due to a lack of reliable witnessed falls with known injury outcomes. The goals of this pilot study were to characterize biomechanical measures and to examine differences in biomechanical measures based on child and fall characteristics in reliable witnessed video-recorded falls involving children. The results of this study will serve as preliminary data for an on-going larger study with the …

Optimization Of Plga And Plga-Dasatinib Particles Through A Taguchi Design Approach, Rayeanne N Balgemann

Electronic Theses and Dissertations

Proliferative vitreoretinopathy (PVR) is a disease of the retina in the human eye. Retinal pigment epithelium cells (RPE) undergo an epithelial to mesenchymal transition in response to retinal trauma. This transition gives the cells mobility and allows them to potentially infiltrate the vitreous chamber and deposit on either side of the retina. Once cell deposition has occurred, along with several other transformed cells derived from cell types such as Müller glia, these migratory cells can form a membrane contiguous with the retinal extracellular matrix and, upon contraction, cause wrinkling of the retina. If left untreated PVR can lead to traction …


Development Of A Capacitive Photocurrent Scanning Microscope With Carrier Depletion Super-Resolution., Austin Levi Carver Jan 2018

Development Of A Capacitive Photocurrent Scanning Microscope With Carrier Depletion Super-Resolution., Austin Levi Carver

Electronic Theses and Dissertations

This dissertation discusses the development and refinement of a new two-dimensional imaging technique, funded in part through a NSF MRI equipment development grant. Capacitive-Photocurrent (CPC) spectroscopy allows for the probing of samples without the requirement of free-carrier collection. The CPC technique allows for the studying of various states within a material. With this electronic measurement technique, we developed a scanning technique, scanning-CPC, that provides two-dimensional material property images without requiring environments that must be high-vacuum, humidity-controlled, or temperature-controlled. This new technique also provides two-dimensional, electronic mapping without damaging samples. With this successful result, we then modified an existing resolution improving …


Detection Of Trace Tetrahydrocannabinol (Thc) Through Surface Enhanced Raman Spectroscopy (Sers) On Microfabricated Platforms, Jack T Lockard Jan 2018

Detection Of Trace Tetrahydrocannabinol (Thc) Through Surface Enhanced Raman Spectroscopy (Sers) On Microfabricated Platforms, Jack T Lockard

Electronic Theses and Dissertations

As an increasing number of states legalize marijuana, it will become necessary to create a method for portable detection and quantification of tetrahydrocannabinol (THC), the principal psychoactive component of cannabis. The ability to identify impaired individuals without the need for traditional drug testing could prove invaluable to law enforcement and employers. Toward this end goal, surface enhanced Raman spectroscopy (SERS) with a silver treated, silicon nanowire substrate was investigated as a method for detection. Acid wet etching of silicon with a hydrofluoric acid (HF) / silver nitrate (AgNO3) was the primary investigation method for this work. Various etching parameters were …
