Nonlinear dynamics of granular assemblies
In this work we investigate granular chains, which are one-dimensional systems of discrete macroscopic particles interacting via the intrinsically nonlinear Hertz law. Such systems support the propagation of solitary waves ... -
A Multi-Scale Molecular Dynamic Approach to the Study of the Outer Membrane of the Bacteria Psudomonas Aeruginosa PA01 and the Biocide Chlorhexidine
The introductory chapters of this thesis contains an explanation to the methods and basic theory of the molecular dynamics approach. Together with the appendix section, in which a step by step tutorial how to set up and ... -
Conservation laws of magnetohydrodynamics and their symmetry transformation properties
All kinematic conservation laws along with their symmetry transformation properties are derived for the system of magnetohydrodynamic equations governing incompressible viscous plasmas (or any other conducting fluid) in ... -
Theory and Application of a Pure-sampling Quantum Monte Carlo Algorithm
The objective of pure-sampling quantum Monte Carlo is to calculate physical properties that are independent of the importance sampling function being employed in the calculation, save for the mismatch of its nodal hypersurface ... -
The Effects of Magnetic Dilution and Applied Pressure on Several Frustrated Spinels
The effects of magnetic dilution and applied pressure on frustrated spinels GeNi2O4, GeCo2O4, and NiAl2O4 are reported. Dilution was achieved by substitution of Mg2+ in place of magnetically active Co2+ and Ni2+ ions. Large ... -
Structural, Magnetic and Thermal Studies of Ce1-xEuxCrO3 Nano-Powders
A new series of nano-sized Ce1-xEuxCrO3 (x = 0.0 to 1.0) with an average particle size of 50 - 80 nm were synthesized using a solution combustion method. Nano-powders Ce1-xEuxCrO3 with the canted antiferromagnetic property ... -
Investigation of Frustrated Quasi-One-Dimensional Quantum Spin-Chain Materials
Copper arsenite CuAs2O4 and Copper antimonite CuSb2O4 are S=1/2 (Cu2+ 3d9 electronic configuration) quasi-one-dimensional quantum spin-chain compounds. Both compounds crystallize with tetragonal structures containing ... -
alpha-Tocopherol's Antioxidant Role: A Biophysical Perspective
(Brock University, 2014-10-30)I present evidence of an antioxidant mechanism for vitamin E that correlates strongly with its physical location in a model lipid bilayer. These data address the overlooked problem of the physical distance between the ...
