Jimmy Raney: blurring the barlines
No full textDespite the institutionalization of jazz music, and the large output of academic activity surrounding the music’s history, one is hard pressed to discover any information on the late jazz guitarist Jimmy Raney or the legacy Jimmy Raney left on the instrument. Guitar, often times, in the history of jazz has been regulated to the role of the rhythm section, if the guitar is involved at all. While the scope of the guitar throughout the history of jazz is not the subject matter of this thesis, the aim is to present, or bring to light Jimmy Raney, a jazz guitarist who I believe, while not the first, may have been among the first to pioneer and challenge these conventions. I have researched Jimmy Raney’s background, and interviewed two people who knew Jimmy Raney: his son, Jon Raney, and record producer Don Schlitten. These two individuals provide a beneficial contrast as one knew Jimmy Raney quite personally, and the other knew Jimmy Raney from a business perspective, creating a greater frame of reference when attempting to piece together Jimmy Raney. In addition, I have taken a look at two arrangements and solos, from what has often been referred to as Jimmy Raney’s seminal years. The results of which showed a great deal of versatility from Jimmy Raney, as the two have little in common. In conclusion, Jimmy Raney helped define a new role for the jazz guitar, with abilities to create spontaneous lines from one song to the next with as much originality as any instrument or musician in the jazz idiom might.M.A.Includes bibliographical referencesby Zachary Streete
A nanostructural study of Raney-type nickel catalysts
No full textRaney-type nickel catalysts have been applied in commercial hydrogenation reactions for decades. They are relatively cheap and have proven to be very efficient in hydrogenation. The preparation process is relatively simple, but it appears that many parameters have an influence on the performance of the final catalyst. Consequently, the manufacturing of Raney-type nickel catalyst with an absolute control of the preparation process is hard to accomplish, leading to unpredictable variation in the catalyst selectivity and activity. A lot of information can be found in literature about characterization of Raney-type nickel catalysts, but many discrepancies exist so that general conclusions are hard to draw. It was the goal of this project to predict the catalytic properties from structure - catalytic performance relationships. Understanding the mechanism of transformation of starting alloys into Raney-type nickel catalysts was then required. To achieve this goal, a detailed characterization at different stages of the leaching process, coupled with the determination of the catalytic properties was performed (chapters 3 and 4). The usual starting alloy used in the preparation of Raney-type nickel catalysts is a 50-50 wt % Ni-Al alloy. As the addition of a second component to metal catalysts is widely used in order to enhance activity and/or selectivity, the effect of Mo, and a combination of Cr and Fe promoters on the performance of Raney-type nickel catalysts has also been investigated (chapter 5). Two extra different approaches in studying Raney-type nickel catalysts have been considered: a rapid solidification technique (melt spinning) to prepare the starting alloy (chapter 6) and the use of cryo-ultramicrotomy to prepare specimens For TEM/HREM characterization (chapter 7).Applied Science
Comparative study on catalytic hydrodehalogenation of halogenated aromatic compounds over Pd/C and Raney Ni catalysts
No full textCatalytic hydrodehalogenation (HDH) has proved to be an efficient approach to dispose halogenated aromatic compounds (HACs). Liquid-phase HDH of single and mixed halobenzenes/4-halophenols with H-2 over 5% Pd/C and Raney Ni catalyst are investigated and compared. For liquid-phase HDH of single HACs, hydrogenolytic scission reactivity of C-X bonds decreases in order of C-Br > C-Cl > C-I > C-F over Pd/C catalyst, and in order of C-I > C-Br > C-Cl > C-F over Raney Ni catalyst. To clarify the reason why hydrogenolytic scission reactivity of C-X bonds over Pd/C and Raney Ni catalysts exhibits different trends, liquid-phase HDH of mixed HACs over Pd/C and Raney Ni catalysts were studied, and catalysts are characterized by SEM, EDX, and XRD techniques. It was found that the high adsorption of iodoarenes on Pd/C catalyst caused the HDH reactivity of iodoarenes to be lower than that of chloroarenes and bromoarenes in the HDH of single HACs. Moreover, the adsorption of in situ produced iodine ion (I-) to catalyst surface would result in the decline of catalytic activity, which might be the main reason why the HDH reactivity of HACs in the presence of NaI is rather low

Raney a novel
No full text"Clyde Edgerton's Raney is the comic love story of a marriage between Raney, a small-town Southern Baptist, and Charles, a librarian with liberal leanings from Atlanta, united by their shared enthusiasm for country music. The novel both interrogates and honors the faiths and foibles of its subjects as the relationship is tested through trials and revelations. Despite the couple's differences, their marriage slowly evolves into a relationship of equals in which both are willing to compromise for the good of the other and the marriage. Told though Raney's naive and mesmerizing perspective as a southern storyteller, serious and sometimes heartbreaking moments give way to a humorous and joyful tale that pokes fun at and holds respect for just about everyone who passes through these pages. Raney, Edgerton's first novel, was originally published in 1985. It represents some of Edgerton's most comic, candid, and ambitious writing. This Southern Revivals edition includes a new introduction by the author and a preface from series editor Robert H. Brinkmeyer Jr., director of the University of South Carolina Institute for Southern Studies."..
Water: the most effective solvent for liquid-phase hydrodechlorination of chlorophenols over Raney Ni catalyst
No full textCatalytic hydrodechlorination (HDC) has proved to be an efficient approach to dispose chlorinated organic compounds (COCs). The influence of solvent on the HOC of chlorophenols with H-2 over Raney Ni catalyst was investigated. We found that protic solvents, especially water, significantly accelerated liquid-phase HOC that was sluggish in aprotic solvents. Among the selected solvents, water was the most effective solvent for liquid-phase HDC over Raney Ni catalyst. To study the mechanism for the rate acceleration in the HOC that was promoted by protic solvents, catalysts were characterized by SEM, EDX, and XRD techniques. It was found that solvent could affect surface composition and surface micro-topography of Raney Ni catalyst. On the basis of these studies, an effective and practical reaction system was developed to dispose chlorophenols over Raney Ni catalyst; a broad range of chlorophenols were efficiently hydrodechlorinated in aqueous solutions under mild conditions, and the catalyst could be reused at least five times without any loss of catalytic activity.

The use of a simple cellular automata model as a testbed for kinetic theories of vehicular traffic flow
No full textDue to the character of the original source materials and the nature of batch digitization, quality control issues may be present in this document. Please report any quality issues you encounter to [email protected], referencing the URI of the item.Includes bibliographical references (leaves 60-63).Issued also on microfiche from Lange Micrographics.The broad objective of this thesis is to explore the potential for the use of Cellular Automata (CA) models to provide a testbed for comparison of different kinetic models of vehicular traffic. We intend to develop a quantitative technique for comparing various kinetic equations that model a given CA-based microscopic model of vehicular traffic. We also plan to apply this technique to two instances of kinetic models, which are differentiated only by their assumptions regarding inter-vehicular correlation and are intended to statistically predict the behavior of ensembles of instances of the underlying CA. We apply different versions of the L��� norm as a metric to compare two kinetic models within two scenarios that are representative of typical vehicular traffic problems. The kinetic models are both derived from the same simple CA traffic model, known as CA-184-CC, but they are based on different models of vehicle correlation: the modified vehicular chaos model; and the Nelson and Raney model, an ad-hoc model developed in an earlier paper by P. Nelson and the author. The traffic scenarios are "near-jam," in which a large traffic jam has a high probability of occurring in a particular location; and "pseudo-free-flow," in which vehicles have a high probability of being spaced out from one another enough to allow driving at the maximum desired speed. Results show that the L[distribution][superscript]��������[w][subscript] norm produces slightly smaller values for the near-jam scenario and significantly smaller values for the pseudo-free-flow scenario. Also, the L[distribution][superscript]��������[w][subscript] norm comparing the CA model to the modified vehicular chaos correlation model is smaller than that of the CA to the Nelson and Raney ad-hoc correlation model, indicating that the modified vehicular chaos model is a better fit to the ensembled CA model
The fishes of the tidewater section of the Pamunkey River, Virginia
No full textThe distribution of the fish fauna of the tidewater section of most of the rivers that flow into Chesapeake Bay is poorly known. Indeed, this is true for practically all the great rivers tributary to the Atlantic from the Hudson southward to the Savannah. The few investigations usually have concentrated on commercial species and our understanding of distribution has been inferred from the knowledge of nearby Coastal Plain streams reported in such studies as those by Hildebrand and Schroeder (1928), Fowler (1945), Raney (1950), and Massmann, Ladd, McCutcheon (1952). In 1949 the junior author began a study of the spawning and early life history of shad in the Pamunkey and other nearby Virginia rivers and collected witli seines at numerous locations in the tidal area. After exploratory seining, many of the stations were visited at almost weekly intervals during the period June 28 to September 29, 1949. Since that time additional collections have been made at established stations on the Pamunkey indicated on the map (Fig. 1).Virginia Institute of Marine Scienc
