Determination Of Mixed Hydrate Thermodynamics For Reservoir Modeling, Nagasree Garapati
Determination Of Mixed Hydrate Thermodynamics For Reservoir Modeling, Nagasree Garapati
Graduate Theses, Dissertations, and Problem Reports (ETD)
Natural gas hydrates are likely to contain more carbon than in all other fossil fuel reserves combined worldwide. Most of the natural gas hydrate deposits contain CH4 along with other hydrocarbon gases like C2H 6, C3H8 and non-hydrocarbon gases like CO 2 and H2S. Thus, if CH4 stored in natural gas hydrates can be recovered, the hydrates would potentially become a clean energy resource for the next 10,000 years. The production of CH4 from natural gas hydrate reservoirs has been predicted by reservoir simulators that implement phase equilibria data to predict various production scenarios.

Characteristics Of Subordinate Follicles Following Removal Of The Dominant Follicle: Induction Of Selection, Matthew Dean
Characteristics Of Subordinate Follicles Following Removal Of The Dominant Follicle: Induction Of Selection, Matthew Dean
Graduate Theses, Dissertations, and Problem Reports (ETD)
In mammals, ovarian follicles begin as primordial follicles. Over time these follicles are gradually activated and begin growth. As they proceed, granulosal and thecal cells are acquired. Eventually, the follicles become dependent on FSH for survival. Two or three times each cycle, a transient increase in FSH allows a cohort of follicles, including the follicle that will ovulate, to continue growing. However, these follicles secrete inhibin and estradiol, which suppress FSH secretion. Eventually, all the follicles of the cohort undergo atresia due to the declining concentrations of FSH, except for the follicle which has the potential to ovulate. This follicle …

Nonlinear Dynamics Modulation In A Neon Glow Discharge Plasma, Paul M. Miller
Nonlinear Dynamics Modulation In A Neon Glow Discharge Plasma, Paul M. Miller
Graduate Theses, Dissertations, and Problem Reports (ETD)
In dynamics modulation, two modes in a driven neon glow discharge alternate as the dominant mode as their response to the driving force alternates between spatiotemporal and temporal periodic pulling. This phenomenon was first noted by Koepke, Weltmann, and Selcher (Bull. Am. Phys. Soc. 40, 1716 (1995)), who saw two limited but representative cases and proposed a mechanism (Phys. Rev. E 62, 2773 (2000)) by which it occurs. The intent of this dissertation is to document experimentally and test the dynamics modulation mechanism they proposed. Using a new extension of a previous mathematical treatment of periodic pulling, the resulting experimental …
Acoustic Plethysmograph For Measuring Pulmonary Function In Mice, Jeffrey S. Reynolds
Acoustic Plethysmograph For Measuring Pulmonary Function In Mice, Jeffrey S. Reynolds
Graduate Theses, Dissertations, and Problem Reports (ETD)
The traditional whole body plethysmograph (WBP) relies on pressure changes induced by a freely respiring animal inside a chamber. This pressure is a combination of a thermo-hygrometric effect (proportional to tidal volume) and a gas compression effect (related to lung mechanics). In order to measure either tidal volume or lung mechanics, it must be assumed that the other component is negligible. In this research, an acoustic WBP was developed that is capable of measuring the thoracic volume change of a mouse independent of the thermohygrometric effect. This allows independent measurement of tidal volume and specific airway resistance.;In the first phase …
