Static Pressure Loss in 12”, 14”, and 16” Non-metallic Flexible Duct
(2013-08-01)
This study was conducted to determine the effects of compression on pressure drops in non-metallic flexible duct. Duct sizes of 12”, 14” and 16” diameters were tested at a five different compression ratios (maximum stretch, ...
Pensamiento Lascasiano e Indigenismo en la Narrativa de Rosario Castellanos
(2013-08-26)
The present dissertation analyzes the influence of the Lascasian thought in the works of Rosario Castellanos throughout Indigenismo. For that effect, an analysis of the trajectory of fray Bartolomé de las Cass and his ...
Rotordynamics of Twin-Screw Pumps
(2013-02-26)
Twin-screw pumps are positive displacement machines. Two meshing screws connected by timing gears convey the fluid trapped in the screw chambers axially from suction to discharge and force it out against the back pressure. ...
Ultra Low Density Shape Memory Polymer Foams with Tunable Physicochemical Properties for Treatment of Intracranial Aneurysms
(2013-05-29)
Shape memory polymers (SMPs) are a rapidly emerging class of smart materials that can be stored in a deformed temporary shape, and can actively return to their original shape upon application of an external stimulus such ...
Experimental Investigation for the Effects of the Core Geometry on the Optimum Acid Flux in Carbonate Acidizing
(2013-11-21)
Previous matrix acidizing experimental research showed that there exists an optimum acid interstitial velocity (Vi-opt) that results in the minimum volume of acid used while providing the best stimulation results. There ...
Coastal Hypoxia on the Texas Shelf: An Ocean Observing and Management Approach to Improving Gulf of Mexico Hypoxia Monitoring
(2013-05-07)
A combination of in situ sampling and real-time ocean observations was used to investigate the processes responsible for the formation and the areal extent of Texas coastal hypoxia from 2002 to 2011. In situ sampling, ...
A Framework of Incorporating Spatio-temporal Forecast in Look-ahead Grid Dispatch with Photovoltaic Generation
(2013-05-02)
Increasing penetration of stochastic photovoltaic (PV) generation into the electric power system poses significant challenges to system operators. In the thesis, we evaluate the spatial and temporal correlations of stochastic ...
The REAL School Garden Experience: Building Sustainable School Gardens through Sustainable Communities
(2013-12-12)
May the end of this journey open the door to new opportunities; I would like to express my deepest gratitude for the members of my advisory committee, Dr. Jonathan Ulmer, Dr. Jennifer Williams, Dr. Landry Lockett, and Dr. ...
Testing a Multicomponent Model of Reading Comprehension for Seventh- and Eighth-Grade Students
(2013-04-27)
Reading is a complex construct with multiple components that have been theorized and empirically tested. Two multicomponent reading comprehension models were tested in this study to extend understanding of the relation of ...
A Computational Study on the Thermal-Hydraulic Behavior of Supercritical Carbon Dioxide in Various Printed Circuit Heat Exchanger Designs
(2013-02-04)
There has been an ever-increasing demand for power generation, which is predicted to grow as society becomes more advanced. However, tradition fossil fuels are beginning to deplete, and there is a great necessity for ...
