Studies on density related indices of white-tailed deer were conducted on the Conservation Research Center (CRC) in Warren County, Virginia from June 1985 to April 1986. Food habits and bark-stripping by deer were also evaluated. Whole body weights, stored fat status, abomasal parasite counts, and blood indices from five deer collected in September on the CRC were compared to deer collected from two reference areas in Southwest Virginia. Abomasal parasite count values for the three areas were recorded as 2568, 1292, and 292. No consistent effects of deer density on physical and physiological indices were observed. Rumen contents from the five deer collected on the CRC were used to determine food habits. The fall diet consisted of green herbage and foliage of woody plants (70% of the total volume) and fruits (30%) such as acorns, apples, and black cherry. No consistent effect of deer density on forage use in meadows was observed on the CRC. Meadow utilization decreased as the growing season progressed. Meadows were utilized more at the edge than 200 m from the edge (P = 0.06). No significant difference (P > 0.05) was found in percentage of dogwood twigs browsed during winter among areas with different deer densities. Fecal crude protein values were higher during summer than winter (P < 0. 0001) but there also was an area-season interaction ( P < 0. 01). Acid detergent fiber values were significantly different areawise (P < 0.01), seasonwise, and areas-season interactionwise (P = 0.0001). Deer density was positively related to winter ADF values. Bark-stripping occurred on slippery elm trees during the winter in a high deer density area. No significant association was found between stripping of slippery elms and age, dbh, and height classes. Protein (P < 0.001) and starch (P < 0.01) contents of the bark were significantly higher in slippery elms than in any other tree species. / M.S.

O objetivo deste trabalho foi desenvolver e implementar uma metodologia envolvendo a análise de perfis de difração de raios X (X-ray Line Profile Analysis - XLPA) para o estudo e determinação do tamanho médio de cristalitos e microdeformação em materiais. Para isto houve o desenvolvimento de um programa computacional para facilitar o tratamento dos picos presentes em um difratograma e realizar a deconvolução de perfis através do Método de Stokes para se corrigir a contribuição instrumental nos perfis de difração. Os métodos de XLPA de espaço real estudados e aplicados neste trabalho foram os métodos de Scherrer, Williamson-Hall e Single-Line (ou Linha Única) e o método de Warren-Averbach de espaço de Fourier. Além disso, utilizando-se um modelamento matemático foi possível calcular a distribuição de tamanhos de cristalitos para um caso isotrópico, onde considerou-se a distribuição log-normal e cristalitos com forma esférica. Foi possível demonstrar que a teoria proposta pode ser considerada como uma boa aproximação avaliando-se uma razão de dispersão. As metodologias descritas acima foram aplicadas em dois materiais distintos: na liga metálica Zircaloy-4 e em ZnO. / The objective of this work was to develop and implement a methodology of X-ray Line Profile Analysis (XLPA) for the study and determination of the mean crystallite sizes and microstrains in materials. A computer program was developed to speed up the treatment of diffraction peaks and perform the deconvolution utilizing the Stokes method to correct the instrumental contribution in the X-ray diffraction measurements. The XLPA methods used were the Scherrer, Williamson-Hall and Single-Line methods, which can be called real space methods, and the Fourier space method of Warren-Averbach. Furthermore, considering a mathematical modelling it was possible to calculate the crystallite size distribution, considering the log-normal distribution and spherical crystallites. It was possible to demonstrate the proposed theory can provide reliable results evaluating a dispersion parameter. The methodologies described above were applied in two distinct materials: in the alloy Zircaloy-4 and in ZnO.

The late 1990's was a time of great wealth and prosperity in the United States. With this economic fervor came a new era of deregulation of the financial services industry. During this time, Congress passed the Financial Services Modernization Act of 1999, otherwise referred to as the Gramm-Leach-Bliley Act (GBLA). This law removed the final barrier (contained in Depression-era Glass-Steagall legislation) between mixing investment banking and commercial banking in the United States. The purpose of this report is to explain the intentions of the law's supporters and detractors, to discuss why this period was a particularly ripe time for such a policy, to examine the leadership decisions that contributed to the passage of GLBA, and to understand the motives behind a "new Glass-Steagall" bill today. This paper focuses only on the deregulatory parts of GLBA relevant to Glass-Steagall's repeal. It does not examine the privacy protections, et al. of GLBA at any length. Also contained in the analysis is a brief discussion of whether GLBA's stated intentions have been violated through the mixing of banking and commerce that has emerged in the present day. Finally, this report ends with a discussion on the fidelity of our national debate on banking regulation, and what it means for the federal government to manage risk in American financial markets in support of the public interest. / text

Currently, there is no standard protocol to identify students who are gifted in science. If students are identified as gifted early on in elementary school, teachers and parents can foster their interest, increasing the students’ knowledge, value, and affect as well as their willingness to re-engage science (Eccles & Wigfield, 2002; Gottfried & Gottfried, 1996; Häussler 1987; Neber & Schommer-Aikins, 2002; Osborne, 2003; Schunk, Pintrich, & Meece, 2008). In this study, a brief student identification form was developed for elementary school teachers to complete. The form was based on Hidi and Renninger’s (2006) four-phase model of interest development. The form was one piece of a more comprehensive identification protocol. Students in grades second, third, fourth, fifth, and sixth from six Warren County elementary schools were asked to participate in this study. However, due to insufficient data, grades two and six were not used after collection. Few sixth grade teachers completed the forms and second graders did not take the ITBS. This study primarily focused on identifying students from underrepresented populations. These six schools, Cumberland Trace, Bristow, Lost River, Oakland, Richardsville, and North Warren, were chosen based on their larger population of students who qualify for free and reduced lunch.
