A NEW ELECTRON SPECTROSCOPY SYSTEM FOR MEASURING ELECTRON EMISSION FROM FAST ION INTERACTIONS WITH ATOMIC, MOLECULAR, AND CONDENSED PHASE TARGETS
(East Carolina University, 2016-07-25)
A new electron spectroscopy system has been developed for measuring electron emission from gas and solid targets induced by fast ion impact. This system uses an ultrahigh-vacuum compatible cylindrical deflector analyzer, ...
MODIFICATION OF CELL SURVIVAL RATES BY CERIUM OXIDE NANOPARTICLES FOR EXPOSURE TO PROTON RADIATION
(East Carolina University, 2017-05-03)
Radiation therapy is a well-established and widely used treatment for a variety of malignancies in the human body. Current radiotherapy methods most frequently use x-rays to deliver a lethal dose to tumors with sufficient ...
Protection and Sensitization of Human Cells to Proton Radiation by Cerium Oxide Nanoparticles
(East Carolina University, 2017-07-17)
In radiation therapy for the treatment of cancer, there is demand for novel approaches that will improve tumor cell killing while protecting healthy tissue. One such approach that has shown considerable promise is the ...
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 ...
Quantitative analysis and comparison of 3D morphology between viable and apoptotic MCF-7 breast cancer cells and characterization of nuclear fragmentation
(2017-09-08)
Morphological changes in apoptotic cells provide essential markers for defining and detection
of apoptosis as a fundamental mechanism of cell death. Among these changes, the
nuclear fragmentation and condensation have ...
Four-Dimensional In Vivo Dosimetry By Dose Reconstruction Using Continuous Epid Images And Phase Sorting Method
(East Carolina University, 2015)
In vivo dosimetry is widely used for patient specific dose evaluation and treatment verification in external beam radiation therapy (EBRT). There is a growing interest in using an electronic portal imaging device (EPID) ...
Study of Morphology Based Cell Assay by Diffraction Imaging Flow Cytometry
(East Carolina University, 2015)
Development of an accurate and label-free method for single cell assay attracts intensive research efforts for its importance to cell biology research and clinicG14G7al applications. Flow cytometry is one of the most widely ...
Graviton and photon orbitals surrounding a black hole : Application to the supermassive black hole at the Milky Way galactic center, with NIR observational confirmation.
(East Carolina University, 2014)
Non-relativistic Quantum Theory fairly accurately describes the resonance phenomena around a black hole, even though black holes are thought of as general relativistic (GR) objects. Graphically and numerically we are able ...
Optical Pulling, Optical Deflection, and Optical Trapping of Single Airborne Particles using Negative Photophoresis
(East Carolina University, 2016-05-03)
Optical manipulation is the use of light to control the motion of objects. This thesis focuses on the development of optical transportation technology via optical pulling with application to the characterization of single ...
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. ...
