Effects Of Electric And Magnetic Fields On Moving Liquid Paint On A Glass Surface, John J. Blalock
Effects Of Electric And Magnetic Fields On Moving Liquid Paint On A Glass Surface, John J. Blalock
Theses & Honors Papers
A Tesla coil is a special type of step-up transformer. It takes an input current at a given frequency and voltage, increases the frequency and voltage via resonant induc tive coupling, and outputs a very high frequency, high voltage current . While it was originally intended as a means of wirelessly transferring energy, the output from a Tesla coil been used in the arts to move paint around on a glass surface using extremely high voltages on the order of 1 megavolt (MV) or 1000000 volts (V). The aim of this project was to scientifically determine what these mechanisms are …
Environmental Analysis Of Toxic Metals Produced By Cigarette Smoking, Catherine H. Swandby, Melissa C. Rhoten, Joseph E. Garcia
Environmental Analysis Of Toxic Metals Produced By Cigarette Smoking, Catherine H. Swandby, Melissa C. Rhoten, Joseph E. Garcia
Theses & Honors Papers
Trace metal elements introduced into our environment from anthropogenic sources can become toxic at high levels contributing to a host of human and animal health problems. The purpose of this work is to initially characterize toxic metals present in cigarette tobacco and ash using Electrothermal Atomic Absorption Spectroscopy (ETAAS). The broader impact of this study is to assess the environmental effects of cigarette smoking around designated smoking areas on the Longwood University campus. Smokers may not be informed about the potential harm to the environment from "ashing" directly on the ground. If the toxic metals present in cigarette ash are …
Neutron Production Analysis On Inertial Electrostatic Deuterium-Deuterium Fusion, Louis Franzel
Neutron Production Analysis On Inertial Electrostatic Deuterium-Deuterium Fusion, Louis Franzel
Theses & Honors Papers
The basic principle of fusion is combining two light nuclei to form one nucleus that is lighter than the combination of the original two. This loss of mass is converted into energy (E=mc2 ) which can be harnessed for various applications. Fusion can take many different and varied forms including: aneutronic fusion, magnetic confinement (MFE), and inertial electrostatic confinement (IEC) to name a few. Fusion is highly adaptable because it can use several different types of fuel such as Deuterium-Tritium, Tritium-Helium-3, Proton-Boron11, and Deuterium-Deuterium mixtures. On top of this, each of the fusion techniques mentioned uses different …
Applications Of Geometric Probability Techniques To The Probability Distribution Of Distances In A Layered Sphere, Duane Smalley
Applications Of Geometric Probability Techniques To The Probability Distribution Of Distances In A Layered Sphere, Duane Smalley
Theses & Honors Papers
Many of the most fundamental forces in nature are dependent of the relative distance between points. The applications of geometric probability techniques to the probability distribution of distances in a layered sphere was studied. Through the use of geometric probability techniques an analysis of a two layered sphere was performed. Using Overhauser’s method, the probability density function was determined for a layered sphere. The research compares the derived probability density function to a Monte Carlo simulation and found that the derived function agrees with the simulation. The program used to create the Monte Carlo simulation was modified from a program …

A New Search For The Neutron Electric Dipole Moment, Crystal Storey
Theses & Honors Papers
The next generation experiments to measure the neutron EDM are being proposed at the Los Alamos National Lab. The use of spin polarized 3He is a critical component of the experiment. Thus measuring the relaxation times of polarized 3He under the actual conditions of the neutron EDM is a crucial step in the success of the experiment. This paper talks about the effort underway at Duke University to measure the relaxation time of polarized 3He at cryogenic temperatures. The applications available in LabView and ExpressPCB have been used extensively in these efforts.
