(Texas A&M University, 2004-09-30)This dissertation is composed of three parts of major contributions. In Chapter II, we discuss analytical study of contaminant transport from a finite source in a finite-thickness aquifer. This chapter provides analytical ...
-
(2009-05-15)Calcium transporters regulate calcium fluxes within cells. Plants, like all organisms, contain channels, pumps and exchangers to carefully modulate intracellular calcium levels. Numerous Arabidopsis proteins have been ...
-
(2011-08-08)A simple Richardson iteration procedure converges slowly when applied to thick, diffusive problems with scattering ratios near unity. The current state of the art for overcoming this is to use a Krylov method with a diffusion ...
-
(Texas A&M University, 2007-04-25)The aim of this study was to determine the effects of density and provision of water on behavior, stress, and weight loss in slaughter horses during transport. A 16.2-m long, single deck, semi-trailer was divided into three ...
-
(2013-07-25)Prenatal stressors have been reported to affect postnatal cognitive, metabolic, reproductive and immune functions. This study examined immune indices and function in Brahman calves prenatally stressed by transportation of ...
-
(Texas A&M University, 2007-09-17)This thesis examines the environmental conditions which led to the loss of 90% of the natural salt marsh in Galveston Island State Park since 1930 and analyzes one potential method to reduce future loss. Available data and ...
-
(2019-01-07)The research presented in this document extends the slice balance approach (SBA) for solving the discrete ordinates neutral particle transport equations. The extended slice balance approach (ESBA) formulated here improves ...
-
(2021-04-09)How phospholipids are transported to different organelles within the cell is a major unsolved question in cell biology. To address this gap in knowledge, I utilized Saccharomyces cerevisiae as a model organism to study ...

Higher Order Discontinuous Finite Element Methods for Discrete Ordinates Thermal Radiative Transfer (2015-07-28)The linear discontinuous finite element method (LDFEM) is the current work horse of the radiation transport community. The popularity of LDFEM is a result of LDFEM (and its Q1 multi-dimensional extensions) being both ...
-
(2018-02-13)Amino acids are the major form of nitrogen (N) transported within the plant body, and their transport between different plant tissues through the xylem and the phloem is indispensable for optimal growth. Such transport ...
-
(2012-02-14)This thesis explores the inverse problem of optical tomography applied to two-dimensional heterogeneous domains. The neutral particle transport equation was used as the forward model to simulate how neutral particles stream ...
-
(2009-06-02)A practical method of reducing aerosolized pathogens and environmental contaminants during commercial transportation could prove beneficial to the health and value of cattle. Having previously determined that there was ...
-
(2012-10-19)Transport, a common cause of stress in livestock, has been documented to increase cortisol, and epinephrine in goats. However, little is known about the timing of changes in the immune system in these stressed animals. The ...
-
(2022-04-11)We develop, analyze, and test iterative methods for three kinds of multigroup transport problems: (1) k-eigenvalue neutronics, (2) thermal radiation transport, and (3) problems with “upscattering,” in which particles can ...
-
(Texas A&M University, 2004-11-15)A quantitative climatology of atmospheric transport in Texas is developed using previously described Lagrangian trajectory methods (Rogers and Bowman, 2001; Bowman and Carrie, 2002). The trajectories are computed using ...
-
(2017-03-01)Accurately measuring and understanding transport mechanisms of liquids in polymers is important for the development of materials used in applications such as packaging, water purification, and corrosion protection. In ...
-
(2013-04-19)The diffusion approximation to the equation of transfer (Boltzmann transport equation) is usually applied to media where scattering dominates the interactions. Diffusion approximation helps in significant savings in terms ...
-
(Texas A&M University, 2006-04-12)A surf zone sediment transport study was conducted in Jamaica Beach, Texas, using new oceanographic equipment. A mini-sled was constructed and outfitted with an instrument package that consisted of two velocimeters, one ...
-
(2016-10-18)Due to limited sources of fossil fuels worldwide and a large percentage wasted as heat energy, searching for efficient thermoelectric materials to convert heat to electricity has gained a great deal of attention. Most of ...
-
(2023-03-14)Statistical mechanics relies on relaxation towards the maximally entropic state in thermal equilibrium. The emergence of statistical mechanics in such systems, known as quantum thermalization, proceeds by the relaxation ...
