"Breakthrough pain" is a common clinical term that has not been conclusively defined or described. Breakthrough pain is a transitory flare of pain experienced when baseline pain has been reduced to a mild or moderate level. Breakthrough pain may be characterized by its relationship to a fixed around-the-clock (ATC) opioid dose, rapid onset and short duration, precipitating events, predictabilit...

Displacement of oil and water in porous media of reservoir rocks is described by relative                      permeability curves, which are important input data for reservoir performance simulation and drive mechanism studies. Many core studies, such as multiphase relative permeability, capillary pressure and saturation exponent determination, depend on the volume fractions of multiphase flui...

In order to generate a data base for the numerical study of dispersion processes in a well defined heterogeneous porous medium, a laboratory tank of 14 m in length, 0.5 m in height and 0.13 m in width has been constructed, which is composed of 81 different elements of exactly known geometry and hydraulic properties. In dispersion experiments using salt as tracer, breakthrough curves are observe...

ACKNOWLEDGEMENTS I would like to thank my adviser Michael Zieve for teaching me to fish. I would like to thank Jeffrey Lagarias for helpful feedback in writing this thesis. I would like to thank my family (Peter, Susan, and Holly), my beautiful girlfriend Becky, and the community of Michigan graduate students for keeping me sane.

[1] The strong jet, with a speed between 500 and 600 m/s, is inferred in the equatorial region of Saturn by combining the nadir and limb observations of Composite Infrared Spectrometer (CIRS) aboard the Cassini spacecraft. A similar jet was discovered on Jupiter (F. M. Flasar et al., 2004a). These discoveries raise the possibility that intense jets are common in the equatorial stratospheres of ...

Fractured rocks play an important role in transport of natural resources through subsurface systems. In recent years, interest has grown in investigating heat transport by means of tracer tests, driven by the important current development of geothermal applications. Many field and laboratory tracer tests in fractured media show that fracture matrix exchange is more significant for heat than mas...

The present study proposes a model to explain the adsorption process through ionexchange membrane adsorbers. The model is defined by the continuity equation, expressed as a differential mass balance of the solute over a section of the membrane, and the Langmuir isotherm. The proposed model uses dimensionless variables that were defined by characteristic times of the global process. To examine t...

HCPB (Helium Cooled Pebbles Bed) Test Blanket Model (TBM) is based on solid breeder. Tritium has to be extracted using Helium purge gas flowing through breeder pebbles bed. He-stream must be cooled down and processed and all these steps are carried out in TES (Tritium Extraction System). A modeling work has been performed to study the behavior of the TES of the HCPB TBM and for Molecular Sieve ...
