An Initial Calibration of a Proton Induced X-ray Emission (PIXE) Material Analysis System Using GUPIXWin
(East Carolina University, 2020-11-17)Proton induced x-ray emission (PIXE) technology has been used extensively over the last few decades to perform highly accurate multi-elemental trace element analyses with much success. The recent implementation of a new ... -
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 ... -
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 ... -
Assessment of single-spot TOPAS MC simulation for proton pencil beam scanning in homogeneous and heterogeneous media and quantification of dosimetric impact of CT metal artifact on IMPT and VMAT plans
(East Carolina University, 2020-11-17)Proton pencil beam scanning (PBS) radiation therapy has become thriving worldwide. The accuracy of proton dose calculation that based on proper modeling for each single scanning spot as well as accurate CT image data is ... -
Biophysical Mechanisms Mediating Fibrin Fiber Lysis
(2017-05-28)The formation and dissolution of blood clots is both a biochemical and a biomechanical process. While much of the chemistry has been worked out for both processes, the influence of biophysical properties is less well ... -
Characterization of critical spawning habitats of weakfish, spotted seatrout and red drum in Pamlico Sound using hydrophone surveys
(1999)Final report for "Characterization of critical spawning habitats of weakfish, spotted seatrout and red drum in Pamlico Sound using hydrophone surveys." -
COMPARATIVE ANALYSIS OF TWO HUMAN CANCER CELL LINES FOLLOWING EXPOSURE TO LOW DOSE RADIATION
(East Carolina University, 2011)Over the past two decades, studies on the cellular response to very low dose radiation have been revolutionizing historically-held paradigms of cellular radioresponse. Indeed, a host of seemingly contradictory events have ... -
COMPARISON OF TWO HUMAN CELL LINES FOLLOWING EXPOSURE TO LOW DOSE RADIATION AND TREATMENT WITH SOYBEAN MISO AND ITS ACTIVE INGREDIENT GENISTEIN
(East Carolina University, 2013)Exposure to radiation is increasingly becoming a worldwide health issue. Because of this, the need for effective radioprotectors is critical. This need is not met by amifostine, the current "gold standard" in radioprotectors, ...
