Synthetic studies of the potent marine toxin, (-)-gymnodimine
(Texas A&M University, 1999)
The enantioselective synthesis of the tetrahydrofuran fragment of (-)-gymnodimine, a potent marine neurotoxin, has been achieved in 13% overall yield and 16 steps from 1,3-propanediol. Key features of the convergent synthesis ...
Merging physical manipulatives and digital interface in educational software
(Texas A&M University, 1999)
During the history of geometry people gradually acquired physical knowledge of space, and later consolidated it in a more abstract form of knowledge, geometry. In this thesis we describe a study performed on fifth grade ...
Development of in vitro screening assays for potentially neurotoxic polyaromatic hydrocarbons in SY5Y and C6 cells
(Texas A&M University, 1999)
Polycyclic aromatic hydrocarbons (PAHs) and halogenated aromatic hydrocarbons (HAHs) are ubiquitous in the environment. Some congeners produce extreme toxicity in laboratory Animal studies. While much attention has been ...
The effects of alpha particle irradiation on stainless steel
(Texas A&M University, 1999)
A Monte Carlo code was developed to calculate the alpha particle emission rate from WGPu. It yielded information pertaining to the alpha particle source strength at the WGPU and stainless steel interface as well as the ...
Role of viscosity in the accurate prediction of source-terms for high molecular weight substances
(Texas A&M University, 1999)
This study shows that using better material property predictions results in better source-term modeling for high molecular weight substances. Viscosity, density, and enthalpy are used as a function of process variables, ...
2-dimensional numerical simulations for the wave-wake-body interactions around circular cylinders in motion near seabed
(Texas A&M University, 1999)
The 2-dimensional, viscous and incompressible flow past a circular cylinder is investigated by solving the Navier-stokes equation. solved using CFD (Computational Fluid These equations are numerically Dynamics) methods on ...
An assessment of the measurement equivalence of rating sources in a multisource feedback system
(Texas A&M University, 1999)
The present study used confirmatory factor analysis to evaluate a series of models representing the relations among performance ratings from multiple sources across multiple performance dimensions. The results suggest that ...
A robust locally preconditioned semi-coarsening multigrid algorithm for the 2-D Navier-Stokes equations
(Texas A&M University, 1999)
The goal of this thesis is to develop an efficient and robust locally preconditioned semi-coarsening multigrid algorithm for the two-dimensional Navier-stokes equations. This thesis examines the performance of the multigrid ...
Effect of primer binding probability on amplified misprimed DNA by means of a computational study on the polymerase chain reaction
(Texas A&M University, 1999)
Amplification of deoxyribonucleic acid (DNA) fragments by the polymerase chain reaction (PCR) has significantly contributed to the rapid development of the modern biomedical sciences. Amplification of DNA fragments is ...
Lithologic characteristics, depositional environments and geometries of reservoir and nonreservoir facies in the Queen Formation (Guadalupian, Permian) of Moose and Virey Fields, Midland County, Texas
(Texas A&M University, 1999)
The Queen Formation is a member of the Artesia Group, which is a sequence of intermingling carbonates, classics and evaporates that were deposited during Guadalupian (Permian) time across the Northwest Shelf, Central Basin ...
