Prediction And Amelioration Of Acid Mine Drainage., Walter Mark Hart

Graduate Theses, Dissertations, and Problem Reports (ETD)

Two aspects of acid mine drainage (AMD) production were studied on a laboratory scale: the role of leaching, and the effectiveness of phosphate amelioration. The leaching study was based on an assumption of an earlier oxidation/leaching field model: that oxidation is independent of leaching. A SAS program was written which can simultaneously fit all three parameters of this field model. The model was generalized to include the effect of initial sulfate sulfur. A deterministic oxidation/leaching model was developed and applied to two continuous, unsaturated flow trickle bed reactors. First-order leaching rate constants were calculated to be 0.0888 days{dollar}\\sp{lcub}-1{rcub}{dollar} for refuse …

Prediction Of Wear In A Fluidized Bed., William Allen Rogers

Graduate Theses, Dissertations, and Problem Reports (ETD)

A procedure to model the wear of surfaces exposed to a fluidized bed is formulated. A stochastic methodology adapting the kinetic theory of gases to granular flows is used to develop an impact wear model. This uses a single-particle wear model to account for impact wear from all possible particle collisions. An adaptation of a single-particle abrasion model to describe the effects of many abrading particles is used to account for abrasive wear. Parameters describing granular flow within the fluidized bed, necessary for evaluation of the wear expressions, are determined by numerical solution of the fluidized bed hydrodynamic equations. Additional …

"Losers At The Game?" Male Protagonists In Four Novels Of Henry James., Sandra Rosalynne Woods

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study examines the male American protagonists from four of Henry James's major novels, Roderick Hudson, The American, The Bostonians, and The Ambassadors. Considerations of the generic Jamesian hero usually include James's heroines, and numerous works have concentrated on James's female protagonists, but few comparable attempts have been made to focus exclusively on James's male protagonists. Both the dynamic character of James's literary career and the extraordinary range of James's female characters suggest that such a study may be warranted. The scale of modes delineated by Northrop Frye in Anatomy of Criticism provides an archetypal base for this study. Because …

Thermomechanical Properties Of Fiber-Reinforced Plastic (Frp) Bars., Wei-Pin Wu

Graduate Theses, Dissertations, and Problem Reports (ETD)

Fiber reinforced plastic (FRP) bars have been recognized as a possible substitution for steel rods because of their noncorrosive properties. However, there is a need to establish sufficient data bank and to develop reliable analytical tools for the analysis of such FRP bars before they could confidently be used and their performance could be predicted and assured in advance. This research is concern with such an effort towards experimental as well theoretical characterization of fiber reinforced plastic (FRP) bars under static loads.

Behavior Of Bolt And Adhesive Connections In Glass Fiber Reinforced Plastic Members, James R. Doyle

Graduate Theses, Dissertations, and Problem Reports (ETD)

Structural fasteners must be engineered to resist a large variety of loading conditions. Isotropic materials with high shear strength can be designed to withstand multidirectional loading. However, since fiber reinforced plastic materials are direction dependent, a more in-depth understanding of the effects of loading direction and fiber orientation is needed. To achieve a better understanding of load transfer and failure mechanisms in FRP fasteners, an experimental program has been devised which includes static testing by varying overlap areas and connector strengths. From the results of these tests, more accurate joint designs should be possible.

Connectors such as arc welding and …

Parent Compliance To Treatment For Pediatric Cancer: Development And Validation Of Two Measurement Strategies., Carita Renee Shawchuck

Graduate Theses, Dissertations, and Problem Reports (ETD)

Investigations of treatment compliance among pediatric cancer patients have indicated that noncompliance to treatment is a significant problem in this population. Some researchers have suggested that compliance to treatment may be significantly influenced by the complexity of the treatment regimen. The purpose of this investigation was to: (a) develop and assess the efficacy of a prospective parent self-monitoring measure to assess compliance to the entire treatment regimen, (b) develop two physician-completed measures to assess the complexity of childhood cancer treatment regimens, and (c) investigate the relationship between current and overall medical regimen complexity and compliance to treatment among a sample …

The Effect Of Board Grade On Yellow Poplar Millwork Cutting Yield., James C. Flowers

Graduate Theses, Dissertations, and Problem Reports (ETD)

The custom millwork industry currently purchases about 89 percent of its hardwood lumber from the top NHLA grades, FAS and FAS1F (1F&Btr). For many millwork producers, the abundance of yellow-poplar in the Appalachian region, its cost and machining properties make it an attractive wood species. The price discrepancies between 1F&Btr yellow-poplar and lower grades are not necessarily justified by observed variation in cutting yield. To determine the effect of NHLA board grade on millwork cutting yields, a database was assembled, detailing information on the type, size and location of defects on the faces of 479 re-graded 4/4 kiln-dried yellow-poplar boards. …
