Development of a Finite Difference Time Domain (FDTD) Model for Propagation of Transient Sounds in Very Shallow Water
(2013-08-12)
We developed a finite difference time domain (FDTD) model for sound propagation using pressure and velocity grids with both three-dimensional Cartesian and two-dimensional cylindrical implementations. Propagation parameters, ...
ANALYTICAL CROSS SECTIONS FOR MOMENTUM TRANSFER TO INNER SHELL ELECTRONS
(East Carolina University, 2011)
The Plane Wave Born Approximation (PWBA), the most prevalent First Born Approximation (FBA), serves as input into theories well beyond the scope of the PWBA. Using Mathematica's advanced symbolic programming capabilities ...
Kinetics of Germination of Individual Spores of as Measured by Raman Spectroscopy and Differential Interference Contrast Microscopy
(2013)
Geobacillus stearothermophilus is a gram-positive, thermophilic bacterium, spores of which are very heat resistant. Raman spectroscopy and differential interference contrast microscopy were used to monitor the kinetics of ...
DOSIMETRIC STUDY OF BETA-MINUS EMITTER PRASEODYMIUM-142 : APPLICATIONS IN MICROSPHERE BRACHYTHERAPY FOR HEPATOCELLULAR CARCINOMA AND BRACHYTHERAPY FOR OCULAR SQUAMOUS CELL CARCINOMA
(East Carolina University, 2013)
A dosimetric study of the beta-minus emitter Praseodymium-142 (¹⁴²Pr) was performed and two main innovative applications of this source in brachytherapy are proposed: microsphere brachytherapy and eye plaque brachytherapy. ...
Correlating the Morphological and Light Scattering Properties of Biological Cells
(East Carolina University, 2013)
The scattered light pattern from a biological cell is greatly influenced by the internal structure and optical properties of the cell. This research project examines the relationships between the morphological and scattering ...
A PROPOSED METHODOLOGY TO ASSESS HDR [superscript]192Ir RADIAL DOSE WITH FRICKE DOSIMETRY
(East Carolina University, 2011)
The radial absorbed dose to water, D(r,theta), a quantity not yet directly measured with primary standards, was assessed with the Fricke solution which has been considered as an absolute aqueous solution to perform dosimetry. ...
Development of a Diffraction Imaging Flow Cytometer for Study of Biological Cells
(East Carolina University, 2010)
Visible light interacts with biological cells primarily through elastic scattering. With coherent excitation the scattered light is coherent as well and contains much information about the cells morphology but with the ...
THE DESCRIPTION OF SCHUMANN ELECTROMAGNETIC RESONANCES BETWEEN EARTH AND ITS IONOSPHERE AS BOSE-EINSTEIN CONDENSATES OF EXTREMELY LOW FREQUENCY PHOTONS
(East Carolina University, 2012)
The purpose of this thesis is to show that Schumann resonances between Earth and its ionosphere are Bose-Einstein condensates of extremely low frequency photons. We will show that the photon densities of the first five ...
Ion Traffic Across Cellular Membranes
(East Carolina University, 2010)
The cell membrane protects the delicate internal machinery of the cell and hosts a complex transport system for ion exchange with the environment. Energy is continually expended to maintain a transmembrane electrical ...
Analysis of Circular Dichroism and Linear Dichroism Spectroscopy
(East Carolina University, 2012)
Circular Dichroism (CD) and Linear Dichroism (LD) spectroscopies measure the difference in absorption between left and right circularly polarized light and parallel and perpendicular linearly polarized light as a function ...
