Stratification in Port Nolloth
The problem set in this project was to study stratification in Port Nolloth society. It was clear from the start that Port Nolloth society was highly stratified, and that the major strata were formed by the White, Coloured and African people in the town. As the study progressed, divisions within …

Stratification in Drying Particle Suspensions
… of recent theories. I further show that stratification can be controlled using thermophoresis induced by a thermal gradient imposed on the drying suspension. To model larger systems on longer time scales, I explore implicit solvent models of drying particle suspensions in which the …

Thermal stratification in solar storage tanks
… of the work was to investigate the thermal stratification in solar storage containers. Three domestic thermally stratified hot water storage containers were designed with the main object of improving and stabilizing thermal stratification of the stored water as a means of improving the …

Stratification on the Skagit Bay tidal flats
Estuarine density stratification may be controlled primarily by cross-shore processes (analogous to longitudinal control in narrow estuaries), or by both cross- and alongshore processes (typical of coastal plumes). Here field observations and numerical modeling are used to investigate …

The Residential Stratification of Mixed-Race Couples
… couples are faring in systems of residential stratification. My dissertation addresses this gap by investigating the extent to which mixed-race couples move into and out of neighborhoods defined by their levels of poverty. I also measure the residential mobility patterns of these couples into …

Cuba's tourist industry: Parallel economies and social stratification
International tourism has played an important role in unintended social changes in socialist countries. These social and cultural changes affect not only the economic, political and cultural genre of the government, but also of its citizens; This thesis asks the question, "Has the re-introduction …

Three Essays on Social Stratification, Gender and Health
This dissertation consists of three essays on health inequalities that arise from interactions between education, gender, and socio-cultural context: gender disparities in the educational gradients in weight status, the gender-specific relationship between mortality of parents and offspring's …

Risk stratification in cardiac surgery: Algorithms and applications
… surgery, to evaluate if the preoperative risk stratification model EuroSCORE predicts the different components of resource utilization in cardiac surgery, and to systematically evaluate the accuracy and performance of artificial neural networks (ANNs) to select and rank the most important risk …

Rayleigh-Taylor mixing: confinement by stratification and geometry
… restriction, by penetration into a stable linear stratification, and by impingement on a stable density interface. Water-based experiments are modelled using a variety of techniques, ranging from simple hand calculation of energy exchange to full three-dimensional numerical simulation. Since there …

SKU stratification methods in the consumer products industry
… by class. Currently, most companies identify SKU stratification based on the single factor of sales volume. This thesis explores more comprehensive analysis methods that can consider multiple SKU characteristics. We applied four methods (Single Factor Analysis, Dual-Matrix Analysis, Analytical …

Stratification transcriptomique de la neurotransmission du gliome humain adulte
… ont permis l’identification d’une nouvelle sous-stratification de gliomes atypiques : un groupe de gliomes ayant un meilleur pronostic par rapport à leurs homologues, potentiellement impacté par la dérégulation significative de marqueurs de la neurotransmission et de l’immunité. Une deuxième …

Complex Crustal Stratification Within the Chugach Mountains, Southern Alaska
… strain analysis, and modeling, a complex ductile stratification of the crust is inferred. I conclude that strain was concentrated within the lower crust, becoming more diffuse in upper ductile levels. This unconventional crustal stratification and vertical strain gradient was consistent with an …
