Physical Motivation and Methods of Solution of Classical Partial Differential Equations

Physical Motivation and Methods of Solution of Classical Partial Differential Equations

Date: August 1995
Creator: Thompson, Jeremy R. (Jeremy Ray)
Description: We consider three classical equations that are important examples of parabolic, elliptic, and hyperbolic partial differential equations, namely, the heat equation, the Laplace's equation, and the wave equation. We derive them from physical principles, explore methods of finding solutions, and make observations about their applications.

A Physiological Age-Grading System for Female Hydrellia pakistanae  Deonier (Diptera: Ephydridae)

A Physiological Age-Grading System for Female Hydrellia pakistanae Deonier (Diptera: Ephydridae)

Access: Use of this item is restricted to the UNT Community.
Date: December 2002
Creator: Lenz, Jennifer Marie
Description: Conflicting opinions about the effectiveness of H. pakistanae as a biological control agent for hydrilla prompt researchers to find a method for assessing the fly's success. Developing a physiological age-grading system for the fly using ovarian morphology to detect changes in reproductive activity is useful for evaluating reproductive status of the fly in field populations. Changes in the appearance of follicular relics in ovaries with oviposition provide a reliable method to estimate fecundity. Characteristics of follicular relics were used to develop a system with eight physiological age classes, three nulliparous and five parous. Changes that occur in the fat body were used to assist in classification of nulliparous females or those with low egg counts.

Physiological and Verbal Responses to Erotic Visual Stimuli in a Female Population

Physiological and Verbal Responses to Erotic Visual Stimuli in a Female Population

Date: December 1972
Creator: Hamrick, Narecia D.
Description: In recent years, there has been a growing acceptance of sexual behavior as a legitimate area of research. An impetus for research utilizing erotic visual stimuli was supplied by the Presidential appointment of the Commission on Obscenity and Pornography (1963). Research into the effects of erotic visual stimuli has typically employed male subjects (Neiger, 1966). The paucity of adequate research has not been a deterrent to the formulation of strong opinions regarding the nature of female sexuality. The present research has focused on female responses to visual representations of the nude male figure.

Physiological Ecology, Population Genetic Responses and Assemblage Stability of Fishes in Two Southwestern Intermittent Stream Systems

Physiological Ecology, Population Genetic Responses and Assemblage Stability of Fishes in Two Southwestern Intermittent Stream Systems

Date: December 1991
Creator: Rutledge, Charles Jerry, 1941-
Description: Six sites within the Denton and Hickory Creek watersheds were sampled over three years to assess the impact of seasonal intermittent stream conditions on the ichthyofauna. An integrated approach using field and laboratory techniques was employed to evaluate the responses of the fishes.

Physiological Effects of Ascaris Suum Intestinal Microflora on 5-Hydroxytryptamine Level and Binding Sites in the Intestinal Epithelial Cells

Physiological Effects of Ascaris Suum Intestinal Microflora on 5-Hydroxytryptamine Level and Binding Sites in the Intestinal Epithelial Cells

Date: December 1991
Creator: Shahkolahi, Akbar Mohammadpour
Description: Serotonin (5-hydroxytryptamine, 5-HT) has been shown to activate carbohydrate metabolism in adult female Ascaris suum. Serotonin may be either absorbed directly from the environment or synthesized de novo from the absorbed L-tryptophan in adult female A. suum. The enzymes necessary for the synthesis of 5-HT have been identified in both intestine and muscle tissues. The serotonin absorbed from the environment is obtained either from the host's gastrointestinal contents or from the 5-HT producing bacteria in the intestine of A. suum. Numerous 5-HT producing bacteria were identified in the intestinal microflora. The physiological contributions of 5-HT producing bacteria to the 5-HT level, turnover and binding sites in the intestinal tissue of A. suum were investigated.

Physiological Effects of Monetary Consequences

Physiological Effects of Monetary Consequences

Date: May 1998
Creator: Kessler, Jeffrey C. (Jeffrey Charles)
Description: Electrodermal responding (EDR) and heart rate (HR) were assessed for seven subjects participating in a reaction time task consequated with monetary bonuses (250, 100, and 10), monetary penalties (250,100, and 10), and a monetary neutral value (00). Unlike previous research employing group designs and a tonic measure (i.e., mean over long periods of time), this study utilized a single-subject design and a phasic measure (i.e., mean over 2-s intervals). Heart rate data was too variable for meaningful analysis. EDR data showed that the peak levels of EDR were higher for penalties than for the corresponding values of bonuses (e.g., -250 vs. +250) for most subjects. Similarly, peak levels of EDR were generally higher during sessions in which consequences were presented than in sessions during which consequences were absent.

The physiology of collaboration: An investigation of library-museum-university partnerships.

The physiology of collaboration: An investigation of library-museum-university partnerships.

Date: August 2003
Creator: Morales Arroyo, Miguel Angel
Description: Collaboration appears to be a magical solution for many problems when there is scarcity of resources, lack of knowledge or skills, and/or environmental threats. However, there is little knowledge about the nature of collaboration. A holistic conceptual framework was developed for the collaborative process, and the conceptualization process used systems thinking approach. The author has selectively chosen conceptualizations and/or research by a limited subset of scholars whose ideas appeared to be the most relevant and useful to explore the type of collaboration studied here. In other words, the selection of the literature was based on an eclectic selection. Multiple cases were used in this research to understand the factors that are components of collaborative effort among non-profit organizations and the relationships among those factors. This study also investigated the stages of collaborative process. Data were collected from 54 participants who were partners in collaborate projects funded by the Institute of Museum and Library Services (IMLS). Among these 54 participants, 50 answered the online questionnaire and 38 received the telephone interviews. The data collected was analyzed using cluster analysis, multidimensional scaling, internal consistency reliability, and descriptive statistics. The component factors of collaboration were grouped by the following seven concepts: trustworthiness, competence, ...

The Piano as an Orchestra: The Accompanist and the Twentieth-Century Orchestral Reduction

The Piano as an Orchestra: The Accompanist and the Twentieth-Century Orchestral Reduction

Access: Use of this item is restricted to the UNT Community.
Date: August 2002
Creator: Lington, Victoria DiMaggio
Description: The musical developments of the 20th century have expanded the role of the accompanist. As the compositional output of our time increases, and the opportunity to perform as soloist with an orchestra diminishes, piano reductions of an orchestral score are becoming the most frequent vehicle for concerto performances of twentieth and twenty-first century instrumental literature. While the current state of research provides solid support to many accompanists, it is in the area of instrumental accompanying, especially with regard to the challenges of playing a reduction of an orchestral score with an instrumental soloist, that the lack of discourse becomes strikingly evident. It is the goal of this study to provide the instrumental accompanist with concrete, practical approaches and considerations in order to perform an orchestral reduction in a manner consistent with the integrity of the score. Problems such as identifying the represented orchestral instruments, delineating importance of musical lines, and basic uses and misuses of pedal, articulation, and rubato are discussed. The pianist is led through ways of deciphering and negotiating specific passages, in order to guide the accompanist through the possible pitfalls and challenges unique to many orchestral reductions. By focusing on twentieth century reductions, providing examples of problems ...
