Study Of The Effects Of Aging On Landmines, Cisr

Global CWD Repository

Most of the mines that currently threaten populations were manufactured more than 50 years ago and many have been in the ground for 30 years or more. Despite the inevitable and obvious deterioration, there has been very little research into the effects of aging on landmines. In 2008, James Madison University (JMU), the Center for International Stabilization and Recovery (CISR), and C King Associates Ltd (CKA) began a study designed to understand the aging process and the range of implications for the various components of mine action. The two-and-a-half year study was funded by grants from the US Department of …

In-Plane Thermal Conductivity Modeling Of Carbon Filled Liquid Crystal Polymer Based Resins, Tayloria N. G. Adams

Dissertations, Master's Theses and Master's Reports - Open

Adding conductive carbon fillers to insulating thermoplastic resins increases composite electrical and thermal conductivity. Often, as much of a single type of carbon filler is added to achieve the desired conductivity, while still allowing the material to be molded into a bipolar plate for a fuel cell. In this study, varying amounts of three different carbons (carbon black, synthetic graphite particles, and carbon fiber) were added to Vectra A950RX Liquid Crystal Polymer. The in-plane thermal conductivity of the resulting single filler composites were tested. The results showed that adding synthetic graphite particles caused the largest increase in the in-plane thermal …

Experimental Determination Of The Weiss Temperature Of Mn12-Ac And Mn12-Ac-Meoh, Christos Lampropoulos, Shiqi Li, Lin Bo, Bo Wen, M P. Sarachik, P Subedi, A D. Kent, Y Yeshurun, A J. Millis, S Mukherjee, G Christou

Chemistry Faculty Research and Scholarship

We report measurements of the susceptibility in the temperature range from 3.5 to 6.0 K of a series of Mn₁₂-ac and Mn₁₂-ac-MeOH samples in the shape of rectangular prisms of length l_c and square cross section of side l_a. The susceptibility obeys a Curie-Weiss law, χ=C/(T−θ), where θ varies systematically with sample aspect ratio. Using published demagnetization factors, we obtain θ for an infinitely long sample corresponding to intrinsic ordering temperatures T_c≈0.85 K and ≈0.74 K for Mn₁₂-ac and Mn₁₂-ac-MeOH, respectively. The difference in T_c for …

Characterization Of Legacy Organic Carbon In A Culturally Eutrophic Lake : The Role Of The Historic Carbon Deposition In The Time Course And Extent Of Lake Recovery , Phillip A. Depetro

Dissertations, Master's Theses and Master's Reports - Open

The time course of lake recovery after a reduction in external loading of nutrients is often controlled by conditions in the sediment. Remediation of eutrophication is hindered by the presence of legacy organic carbon deposits, that exert a demand on the terminal electron acceptors of the lake and contribute to problems such as internal nutrient recycling, absence of sediment macrofauna, and flux of toxic metal species into the water column. Being able to quantify the timing of a lake’s response requires determination of the magnitude and lability, i.e., the susceptibility to biodegradation, of the organic carbon within the legacy deposit. …

Quantification Of Relativistic Perturbation Forces On Spacecraft Trajectories, Nicholas Palma Mastricola

Dissertations, Master's Theses and Master's Reports - Open

The intent of the work presented in this thesis is to show that relativistic perturbations should be considered in the same manner as well known perturbations currently taken into account in planet-satellite systems. It is also the aim of this research to show that relativistic perturbations are comparable to standard perturbations in speciffc force magnitude and effects. This work would have been regarded as little more then a curiosity to most engineers until recent advancements in space propulsion methods { e.g. the creation of a artiffcial neutron stars, light sails, and continuous propulsion techniques. These cutting-edge technologies have the potential …

Energy Harvesting From Body Motion Using Rotational Micro-Generation, Edwar. Romero-Ramirez

Dissertations, Master's Theses and Master's Reports - Open

Autonomous system applications are typically limited by the power supply operational lifetime when battery replacement is difficult or costly. A trade-off between battery size and battery life is usually calculated to determine the device capability and lifespan. As a result, energy harvesting research has gained importance as society searches for alternative energy sources for power generation. For instance, energy harvesting has been a proven alternative for powering solar-based calculators and self-winding wristwatches. Thus, the use of energy harvesting technology can make it possible to assist or replace batteries for portable, wearable, or surgically-implantable autonomous systems. Applications such as cardiac pacemakers …

Energy Of The Conduction Band In Near Critical Point Fluids, Cherice M. Evans, G. L. Findley

Publications and Research

The study of the evolution of the conduction band in dense gases and supercritical fluids near the critical point has been complicated by a lack of precise experimental measurements. Both photoemission from an electrode immersed in the fluid and field ionization of a molecule doped into the fluid have been used to probe solvent density effects on the energy of an excess electron as a function of fluid number density and temperature. In this perspective, we present recent experimental results that show a strong critical point effect on the minimumconduction band energy near the critical density and temperature of a …

Technology And Its Role In Teacher Education, Zelda Mcmurtry, Candice Burkett

Teacher Education Faculty Publications

This chapter discusses technology and its role in teacher education. In order for technology to reach the early childhood classroom, it must first reach the classroom of the teacher education programs. The effect of self-efficacy on preschool teachers use and understanding of technology may influence their instructional applications. Early childhood faculty come from the same career pool as early childhood teachers and may share the same beliefs that practitioners have concerning technology. Teacher education programs have a responsibility to produce professionals who are literate in technology tools and applications.

School Psychologists' Knowledge Of Tourette Syndrome Characteristics And Awareness Of Appropriate Interventions, Jesse Usher Glassman

PCOM Psychology Dissertations

Tourette Syndrome (TS) is a neurodevelopmental disorder consisting of multiple involuntary motor tics and one or more vocal tics. The duration of the disorder is at least one year and not more than three consecutive tic-free months (APA, 2000). The tics associated with TS are frequently more severe than other tic disorders on the spectrum. There are varying degrees of severity of TS disorder, requiring maximum to no treatment. Children and adolescents diagnosed and who are showing signs of TS are referred for school evaluations in order to identify various learning difficulties and /or emotional issues which are often associated …

The Relevance Of Executive Functions In Academic Production In Middle School, Norina Bobik

PCOM Psychology Dissertations

The present study investigated the role that executive function plays on academic production in middle school from a prototype perspective. It was hypothesized that middle school teachers' prototypical ratings of the executive function capacities of middle school students who are academically successful would differ significantly from these same middle school teachers' prototypical ratings of the executive function capacities of middle school students who are academically unsuccessful. The study used archival data consisting of items from the Behavior Rating Inventory of Executive Function (BRIEF), a questionnaire that was completed by middle school teachers during a professional in-service workshop at four large …

A Trusted Storage System For The Cloud, Sushama Karumanchi

University of Kentucky Master's Theses

Data stored in third party storage systems like the cloud might not be secure since confidentiality and integrity of data are not guaranteed. Though cloud computing provides cost-effective storage services, it is a third party service and so, a client cannot trust the cloud service provider to store its data securely within the cloud. Hence, many organizations and users may not be willing to use the cloud services to store their data in the cloud until certain security guarantees are made. In this thesis, a solution to the problem of securely storing the client’s data by maintaining the confidentiality and …

Dielectrophoretic Choking Phenomenon In A Converging-Diverging Microchannel, Ye Ai, Shizhi Qian, Sheng Liu, Sang W. Joo

Mechanical & Aerospace Engineering Faculty Publications

Experiments show that particles smaller than the throat size of converging-diverging microchannels can sometimes be trapped near the throat. This critical phenomenon is associated with the negative dc dielectrophoresis arising from nonuniform electric fields in the microchannels. A finite-element model, accounting for the particle-fluid-electric field interactions, is employed to investigate the conditions for this dielectrophoretic (DEP) choking in a converging-diverging microchannel for the first time. It is shown quantitatively that the DEP choking occurs for high nonuniformity of electric fields, high ratio of particle size to throat size, and high ratio of particle's zeta potential to that of microchannel. © …

Fairness, Justice And An Individual Basis For Public Policy, Douglas R. Oxley

Department of Political Science: Dissertations, Theses, and Student Research

Prior models of the policy process have examined how human characteristics can affect policy decision-making in such a way that it leads to aggregate effects on policy outcomes as a whole. I develop a model of the policy process which suggests that emotions related to fair and unfair experiences in the same policy domain are utilized by decision-makers as policy criteria. In the lab, I empirically tested this, and find that emotions and experience related to fairness do influence the policy decision to move away from the status quo alternative. Based upon this result, I simulated the evolution of a …

Electrical Characterization Of Buckled Graphene Films Derived From Plasma Etched Silicon Carbide., Tobias Denig

Graduate Theses, Dissertations, and Problem Reports (ETD)

Graphene is a 2D allotrope of carbon with exceptional electronic properties and numerous applications. Research in the Surface and Materials Studies Laboratory at West Virginia University has led to the development of a low temperature, halogen based plasma etching process that produces buckled graphene films on 6H-SiC. Films ranging from one to five layers in thickness have been produced. This growth process is scalable with the SiC wafer diameter, and in principle, it resolves many of the difficult issues associated with the manufacturability of large area epitaxial graphene films. The growth process and functionalization of these buckled graphene films have …
