An Evaluation of Comparative Piano Technique Since 1902

Description: There are no figures available, but if a survey were made, possibly more people would be found engaged in the study and teaching of piano than any other musical instrument. It is much to be desired for both teachers and students to have an intimate acquaintance with the principles underlying the structure of modern piano technique. The situation as it generally exists contrasts sharply with the ideal situation. The ignorance of this important phase of piano study causes an enormous annual waste of time and money on the part of students. With an adequate technical knowledge, teachers, instead of allowing their pupils to practice blindly and mechanically, would be able to explain the reason for each movement they ask them to perform. Many failures in both classes occur because of the lack of understanding of what piano playing requires.

Evaluation of dynamic and static electrical characteristics for the DY8 and YI8 process gallium diodes in comparison to the DI8 process boron diodes.

Description: A rectifier is an electrical device, comprising one or more semiconductor devices arranged for converting alternating current to direct current by blocking the negative or positive portion of the waveform. The purpose of this study would be to evaluate dynamic and static electrical characteristics of rectifier chips fabricated with (a) DY8 process and (b) YI8 process and compare them with the existing DI8 process rectifiers. These new rectifiers were tested to compare their performance to meet or exceed requirements of lower forward voltages, leakage currents, reverse recovery time, and greater sustainability at higher temperatures compared to diodes manufactured using boron as base (DI8 process diodes) for similar input variables.

Evaluation of Ethanol’s Effects on the Biophysical Characteristics of Licking

Description: Alcohol use disorders are a public health issue related to adverse effects for individuals and society. A low level of response, or decreased sensitivity, to alcohol has been identified as a heritable risk factor for development of alcohol use disorders. One method for researching level of response to alcohol is through the use of rodent models, which are developed to mimic human conditions while eliminating barriers to conducting research with people. Current rodent models used to evaluate effects of ethanol on motor performance have been criticized for not being well matched to human tasks that measure level of change in body sway after alcohol consumption. This study looks at oromotor behavior as a potential alternative to gross motor performance in hopes of increasing correspondence between human and rodent measures of intoxication. To evaluate rodent oromotor performance a force transducer lickometer is used to measure several dimensions of licking behavior after administration of different concentrations of ethanol solution via gavage. Results show that force of licking is not sensitive to dose of ethanol. The total number of licks per session show dose related decreases and licking rhythm, evaluated by the length and distribution of interlick intervals, either increased or decreased for three of the four subjects. Recommendations are made for procedural modifications in order to reduce variability in data and further investigate oromotor performance and level of response to alcohol.

Evaluation of Fine Particulate Matter Pollution Sources Affecting Dallas, Texas

Description: Dallas is the third largest growing industrialized city in the state of Texas. the prevailing air quality here is highly influenced by the industrialization and particulate matter 2.5µm (PM2.5) has been found to be one of the main pollutants in this region. Exposure to PM2.5 in elevated levels could cause respiratory problems and other health issues, some of which could be fatal. the current study dealt with the quantification and analysis of the sources of emission of PM2.5 and an emission inventory for PM2.5 was assessed. 24-hour average samples of PM2.5 were collected at two monitoring sites under the Texas Commission on Environmental Quality (TCEQ) in Dallas, Dallas convention Centre (CAMS 312) and Dallas Hinton sites (CAMS 60). the data was collected from January 2003 to December 2009 and by using two positive matrix models PMF 2 and EPA PMF the PM2.5 source were identified. 9 sources were identified from CAMS 312 of which secondary sulfate (31% by PMF2 and 26% by EPA PMF) was found to be one of the major sources. Data from CAMS 60 enabled the identification of 8 sources by PMF2 and 9 by EPA PMF. These data also confirmed secondary sulfate (35% by PMF2 and 34% by EPA PMF) as the major source. to substantiate the sources identified, conditional probability function (CPF) was used. the influence of long range transport pollutants such as biomass burns from Mexico and Central America was found to be influencing the region of study and was assessed with the help of potential source contribution function (PSCF) analysis. Weekend/weekday and seasonal analyses were useful in understanding the behavioral pattern of pollutants. Also an inter comparison of the model results were performed and EPA PMF results was found to be more robust and accurate than PMF 2 results.

An Evaluation of Fish and Macroinvertebrate Response to Effluent Dechlorination in Pecan Creek

Description: This study evaluated the effects of chlorinated effluent discharged from the City of Denton, Texas' wastewater treatment plant on Pecan Creek's fish and macroinvertebrate assemblages, and their recovery upon dechlorination. A baseline of ecological conditions was established while chlorine was present in the effluent (June 1993- October 1993), and was evaluated again after dechlorination with sulfur dioxide (October 1993-August 1994). In situ Asiatic clam and fathead minnow ambient toxicity tests, and fish and macroinvertebrate collections were used to establish this baseline for comparison to post-dechlorination results.

Evaluation of hydrogen trapping in HfO2 high-κ dielectric thin films.

Description: Hafnium based high-κ dielectrics are considered potential candidates to replace SiO2 or SiON as the gate dielectric in complementary metal oxide semiconductor (CMOS) devices. Hydrogen is one of the most significant elements in semiconductor technology because of its pervasiveness in various deposition and optimization processes of electronic structures. Therefore, it is important to understand the properties and behavior of hydrogen in semiconductors with the final aim of controlling and using hydrogen to improve electronic performance of electronic structures. Trap transformations under annealing treatments in hydrogen ambient normally involve passivation of traps at thermal SiO2/Si interfaces by hydrogen. High-κ dielectric films are believed to exhibit significantly higher charge trapping affinity than SiO2. In this thesis, study of hydrogen trapping in alternate gate dielectric candidates such as HfO2 during annealing in hydrogen ambient is presented. Rutherford backscattering spectroscopy (RBS), elastic recoil detection analysis (ERDA) and nuclear reaction analysis (NRA) were used to characterize these thin dielectric materials. It was demonstrated that hydrogen trapping in bulk HfO2 is significantly reduced for pre-oxidized HfO2 prior to forming gas anneals. This strong dependence on oxygen pre-processing is believed to be due to oxygen vacancies/deficiencies and hydrogen-carbon impurity complexes that originate from organic precursors used in chemical vapor depositions (CVD) of these dielectrics.

An evaluation of job satisfaction among salespersons in a small department store using four psychological measures.

Description: The purpose of this study was to examine the potential of three independent psychological scales (Rotter's Locus of Control, Karasek's Job Content Questionnaire [non-injury job stress], and Rosenberg's Self-Esteem Scale) to predict job satisfaction, as measured by Brayfield and Rothe's Index of Job Satisfaction, among salespersons in a small independent department store in Wichita Falls, Texas. An 82-item survey which examined the dynamics of a salesperson's work life was administered to 20 individuals who were full-time employees of the department store. Demographic data were also gathered although these factors were not entered into the regression analysis. A multiple regression procedure examined the responses of the 20 employees who participated in the study. The R-squared coefficient indicates that 41 percent of the variance in Job Satisfaction was explained by the three predictor measures. A major proportion of this unexplained variance may be in variables outside the scope of this study, e.g., salaries, vacation time, benefits, bonuses, or commissions. Results suggest that the independent variables measured by the Locus of Control Scale and the Job Content Questionnaire in combination were the best predictors of job satisfaction with a significance level of .01. The single best predictor was the Job Content Questionnaire, significant at .03. The three instruments (Locus of Control, Self-Esteem, and Job Content Questionnaire) which comprised the independent variables, reached a significance level of .03 in their prediction of job satisfaction (Brayfield-Rothe Index of Job Satisfaction). Study results indicate that a majority of the employees in the sample population were satisfied with their jobs and with the leadership style manifested by the store manager. In addition, job security was believed to be satisfactory. Inasmuch as there is a void in the literature regarding personal characteristics of salespersons as variables that interact with job satisfaction, comparisons of the findings of this research ...
