Traffic accidents have become a major issue for researchers, academia, government and vehicle manufacturers over the last few years. Many accidents and emergency situations frequently occur on the road. Unfortunately, accidents lead to health injuries, destruction of some infrastructure, bad traffic flow, and more importantly these events cause deaths of hundreds of thousands of people due to not getting treatment in time. Thus, we need to develop an efficient and smart emergency system to ensure the timely arrival of an ambulance service to the place of the accident in order to provide timely medical help to those injured. In addition, …

Numerical Reconstruction Of Spalled Particle Trajectories In An Arc-Jet Environment, Raghava S. C. Davuluri, Sean C. C. Bailey, Kaveh A. Tagavi, Alexandre Martin

Mechanical Engineering Faculty Publications

To evaluate the effects of spallation on ablative material, it is necessary to evaluate the mass loss. To do so, a Lagrangian particle trajectory code is used to reconstruct trajectories that match the experimental data for all kinematic parameters. The results from spallation experiments conducted at the NASA HYMETS facility over a wedge sample were used. A data-driven adaptive methodology was used to adapts the ejection parameters until the numerical trajectory matches the experimental data. The preliminary reconstruction results show that the size of the particles seemed to be correlated with the location of the ejection event. The size of …

It is commonly assumed that charge-carrier transport in doped π-conjugated polymers is dominated by one type of charge carrier, either holes or electrons, as determined by the chemistry of the dopant. Here, through Seebeck coefficient and Hall effect measurements, we show that mobile electrons contribute substantially to charge-carrier transport in π-conjugated polymers that are heavily p-doped with strong electron acceptors. Specifically, the Seebeck coefficient of several p-doped polymers changes sign from positive to negative as the concentration of the oxidizing agents FeCl3 or NOBF4 increase, and Hall effect measurements for the same p-doped polymers reveal that …

Earth and Environmental Sciences Faculty Publications

Because incomplete confirmation is available concerning the influential role of atmosphere contamination on conjunctivitis, myopia, asthma, and allergic rhinitis in Brazil, the focus of the present work is to explore the possible relations among atmosphere contamination and eye problems. Rather that a case study on eye diseases, by way of questionnaires supplemented by the investigation of nanoparticles (NPs) on eyeglasses, the study examines the mechanisms in which NPs and ultra-fine particles are deposited on the glasses of children up to 10 years of age in urban and rural area. The important connection between atmosphere contaminants and individual protection equipment justifies …

Analyzing Slab Holes In Subduction Zones And Their Impacts Through Numerical Simulations, Taylor M. Arrowood

Theses and Dissertations--Earth and Environmental Sciences

Subduction zones form as higher density oceanic lithosphere is forced beneath an over-riding, lower density, continental or oceanic plate; a process driven by contrasts in buoyancy throughout this system. We seek to explore subduction zones in which the subducting lithosphere is discontinuous after passing through the trench, forming a slab gap. The main research objective is to determine the effect of slab gaps on surface topography in a subduction-related orogen and asthenospheric flow into the mantle wedge using two and three-dimensional numerical mechanical models. We obtain results from 24+ models that suggest a connection between slab gaps/holes and the magnitude …

Timing Of Regional Metamorphism In The Inner Piedmont And Blue Ridge Of North Carolina: Evidence From Monazite U-Pb Geochronology, Nicholas Edwin Powell

Theses and Dissertations--Earth and Environmental Sciences

Channel and escape flow, or lower crustal ductile flow and redirection from orogen-normal to orogen-parallel flow, are among the most impactful concepts introduced to explain shortening accommodation in large, hot orogens. In the Inner Piedmont (IP), southern Appalachians, channel and escape flow were proposed to have occurred during the Neo-Acadian (376–340 Ma) orogeny. However, the polymetamorphic history of the southern Appalachians makes it difficult to isolate thermal and deformational events for process-focused studies necessary to test these ideas in the IP. To address this, we used in situ laser ablation split stream (LASS) monazite U-Pb geochronology alongside new garnet chemical …

Admittance Modeling For Elastic Thickness Across The Mars Crustal Dichotomy Boundary, Aspen Davis

Theses and Dissertations--Earth and Environmental Sciences

We use a Bouguer mass-sheet approximation for spectral admittance and correlation modeling to estimate elastic thickness, crustal thickness, crustal density, and load density across the Mars crustal dichotomy boundary near the landing site of NASA’s InSight Lander. We derive and constrain the parameter ranges using RMS misfit between the observed and theoretical admittance and their error bars. Spherical cap windows of 15° (900 km) radius are used to study 15 locations in the Northern Lowlands, the Southern Highlands and near and on the boundary which suggest distinct, but not sharp, difference in lithospheric properties. Elastic thickness estimates range generally between …

Biofilm And Cell Adhesion Strength On Dental Implant Surfaces Via The Laser Spallation Technique, James D. Boyd, Arnold J. Stromberg, Craig S. Miller, Martha E. Grady

Statistics Faculty Publications

OBJECTIVE: The aims of this study are to quantify the adhesion strength differential between an oral bacterial biofilm and an osteoblast-like cell monolayer to a dental implant-simulant surface and develop a metric that quantifies the biocompatible effect of implant surfaces on bacterial and cell adhesion.

METHODS: High-amplitude short-duration stress waves generated by laser pulse absorption are used to spall bacteria and cells from titanium substrates. By carefully controlling laser fluence and calibration of laser fluence with applied stress, the adhesion difference between Streptococcus mutans biofilms and MG 63 osteoblast-like cell monolayers on smooth and rough titanium substrates is obtained. The …

These algorithms and frameworks are assessed mainly on substance use disorders prediction tasks and specifically designed to tackled these disorders. Substance use disorder is a public health crisis costing the US an estimated $740 billion annually in …

Investigations Into The Genetics Of Mixed Pathologies In Dementia, Adam Dugan

Theses and Dissertations--Epidemiology and Biostatistics

Alzheimer’s disease (AD) is an irreversible, progressive brain disorder that leads to a loss of memory and thinking skills. While tremendous progress has been made in our understanding of the genetics underlying AD, currently known genetic variants explain only approximately 30% of the heritable risk of developing AD. One hurdle to AD research is that it can only be definitively diagnosed at autopsy, making cruder, clinic-based diagnoses more common. In recent years, several brain pathologies that mimic AD’s clinical presentation have been identified including brain arteriolosclerosis, hippocampal sclerosis (HS), and, most recently, limbic-predominant age-related TDP-43 encephalopathy (LATE). It has become …

Integrated Geophysical Investigation Of Near-Surface Faults - Sassafras Ridge, New Madrid Seismic Zone, Usa, Cooper Cearley

Theses and Dissertations--Earth and Environmental Sciences

The New Madrid Seismic Zone (NMSZ) is a large source of seismic hazard within the central and eastern United States. Seismogenic source parameters such as active fault location, slip rate, total displacement, and strain accommodation is poorly constrained due to the masking effect of the Mississippi Embayment sediment and agricultural practices on structures and surface expressions. Consequently, noninvasive geologic and geophysical investigation of the subsurface is needed to characterize seismogenic sources. Recent investigation of the Reelfoot Fault found that there is a strain accommodation enigma between the dextral offset at seismogenic depth versus the surface expression, Reelfoot Scarp. This strain …

What's In The Pan: An Evaluation Of Fragipan Evolution In Western Kentucky, Hannah Leigh Somerville

Theses and Dissertations--Plant and Soil Sciences

The fragipan is a common diagnostic soil feature that does not follow a clear development path. Fragipans are found commonly throughout the southeastern US and cover 2.7 million acres in Kentucky alone. However prevalent, there is no currently accepted genesis theory for fragipans. In this study, we sought to better understand the formation of fragic features in Kentucky’s soils by evaluating fragipan characteristics across a sequence of pedons featuring varying degrees of fragipan development. We found that [Si/Al]_Dithionite, [Si/(Si + Al)]_Dithionite and Si_Dithionite concentration were all higher in well-developed fragipans, suggesting the involvement of an aluminosilicate …

Selenium Removal And Pollution Swapping Potentials Of Passive Anaerobic Bioreactors Receiving Coal Slurry Impoundment Wastes, Md Anik Mahmud

Theses and Dissertations--Plant and Soil Sciences

Worldwide, selenium is a major contaminant of concern for coal and metal ore mining industries. In coal mining regions of the eastern USA, for example, billions of liters of wastewaters with elevated Se oxyanion concentrations (primarily SeO₄^2- and SeO₃^2-) are generated during coal washing which is often stored in > 700 man-made impoundments built into remote mountain valleys. Because impoundments are unlined systems, they tend to leak contents into nearby streams, which has detrimental effects on sensitive biota, particularly fish. The primary goal of this project was to evaluate the capacity of passive anaerobic bioreactors (PAB) …
