Fabrication And Characterization Of Antioxidant Loaded Liposomes., Brian Gettler
Fabrication And Characterization Of Antioxidant Loaded Liposomes., Brian Gettler
Electronic Theses and Dissertations
Radiation exposure is both a major obstacle in space exploration and an occupational hazard for various careers causing DNA damage and ROS. In order to reduce the effects of radiation, the primary and most explored approach has been focused around mitigation in terms of exposure duration, exposure intensity, and shielding usage. In some situations none of these reduction strategies were viable and so the use of antioxidants is being explored as an alternate strategy for therapeutic purposes. One such antioxidant is curcumin, otherwise known as diferuloylmethane, is a component of turmeric with both antioxidant properties and anti-inflammatory properties. Another antioxidant …

Real-Time Bio Sensing Using Micro-Channel Encapsulated Mems Resonators, Ayesha Iqbal
Electronic Theses and Dissertations
This work presents a label-free bio-molecular detection technique based on realtime monitoring of the resonant frequency of micromechanical thermal-piezoresistive rotational mode disk resonators encapsulated in microfluidic channels. Mass loading via adsorption of molecular layers on the surface of such devices results in a frequency shift. In order to provide a reliable platform for sample-resonator interactions and to protect the resonators from contaminants, the resonators were encapsulated in PDMS-based microfluidic channels. Micro-channel encapsulation also allows insulation of electrical signals from the analyte solution. To characterize the performance of such devices as real-time label-free bio-molecular detectors, the strong non-covalent binding of Avidin …

Design Of The High-Speed Stereo Radiography System, John C. Ivester Iv
Electronic Theses and Dissertations
Orthopaedic pathologies often involve disruption of the mechanical environment of a joint at/below the mm scale. The ability to measure biomechanical kinematics at the sub-mm scale is essential for obtaining valuable insight into pathologies, but small motions of the joints are difficult to quantify. Estimates of skeletal kinematics are commonly made from optical motion capture systems and markers placed on the skin. The error caused by external marker movement is largely avoided with x-ray motion capture. Dynamic radiography uses a series of x-ray images recorded at high-speed and captures in-vivo joint motion. Uncovering the mechanical foundation of orthopaedic pathologies requires …

Development Of An Application For Patient-Centered Dementia Care., David Collar Alston
Electronic Theses and Dissertations
Dementia care in the United States faces several challenges, many of them associated with managing the information that is associated with patients. Protected patient information about patients is often separated between many sources. For example, a new doctor may have information on patient medicines, but not the document associated with the caregiving goals of the patient and their family. Problems can develop if a patient is treated by a new caregiver, who may not know the patient’s treatment and behavior history. There is a strong desire for a system that can collect, organize, and analyze patient information in a user …
Neuromodulation Based Control Of Autonomous Robots On A Cloud Computing Platform, Cameron Muhammad
Neuromodulation Based Control Of Autonomous Robots On A Cloud Computing Platform, Cameron Muhammad
Electronic Theses and Dissertations
In recent years, the advancement of neurobiologically plausible models and computer networking has resulted in new ways of implementing control systems on robotic platforms. The work presents a control approach based on vertebrate neuromodulation and its implementation on autonomous robots in the open-source, open-access environment of robot operating system (ROS). A spiking neural network (SNN) is used to model the neuromodulatory function for generating context based behavioral responses of the robots to sensory input signals. The neural network incorporates three types of neurons- cholinergic and noradrenergic (ACh/NE) neurons for attention focusing and action selection, dopaminergic (DA) neurons for rewards- and …
