A Rutherford backscattering spectrometry facility has been designed and built at the University of Arizona. Initial calibration and testing has been carried out in order to accurately characterize the system and make it ready to perform reliable analyses. Also, an explanation of basic RBS principles has been presented to enable persons unacquainted with the technique to determine its applicability for various types of analytical problems. A method for determining the concentration profile of Ag in an SiO₂ matrix is carefully explained. Calculations derived from basic principles are demonstrated for this analysis and can be applied in a number of similar circumstances. Several other examples of analyses of utilizing various operating parameters are explained and illustrated. Some examples of unusual samples are shown to be feasible for analysis by this technique. RBS is shown to be a very useful analytical tool for a wide variety of samples. It has the capability of performing quantitative depth profiles without standards. The vast potential for its use by analytical chemists is demonstrated, and future improvements for this particular facility are discussed.

Orientador: Sidney Barbosa / Banca: Zélia Lopes da Silva / Banca: Telma Campanha de Carvalho Madio / Resumo: O objetivo desta pesquisa é o de analisar imagens fotográficas da cidade de Cuiabá (MT) da década de 1920. Procedemos essa análise com o propósito de se efetuar a leitura, a identificação e a representação, por meio da elaboração de resumo e da geração de descritores, para permitir a recuperação dos conteúdos informacionais, referentes ao contexto sócio-histórico e cultural da cidade, subjacentes nas imagens. Procedemos à análise de vinte fotografias, agrupadas em seus núcleos temáticos que abrangem os monumentos arquitetônicos, os espaços públicos e privados, os retratos de família, os meios de transportes, o vestuário e o lazer. Dentre os resultados alcançados estão, além das discussões teóricas propiciadas pela revisão bibliográfica, a apresentação das análises demonstrando as possibilidades de procedimento, tanto em relação à elaboração de textos-resumos a partir de leituras das imagens, quanto à apresentação de descritores denotativos e conotativos que representam o conteúdo imagético. Visamos, com isso, contribuir com a preservação da memória social local, bem como com a área da Ciência da Informação, mais especificamente com o tratamento da informação, na medida em que se realiza uma abordagem e uma proposição de procedimentos metodológicos capazes de colaborar com o tratamento informacional de acervos fotográficos. / Abstract: The aim of this research is to analyse photographs from the city of Cuiabá in the 1920's. The proposal of this analysis is based on readings, identifying and representing, by means of summarizing and describing so that informative content related to the socio-historical and cultural context of the city can be recuperated using underlying images. The analysis was carried out using twenty photographs grouped into different thematic sets which range from the architectural monuments, public and private spaces, family portraits, means of transportation, fashion and leisure. Among the results obtained, and theoretical discussions provided by the bibliography, are analyses which show the possibilities of procedure both in relation to summarized texts from readings of the images, as well as denotative and connotative descriptions which represent the content of the images. Taking this into account, this work can contribute to the conservation of local social memories, as well as Information Science, more specifically dealing with information in terms of carrying out an approach and a proposal of methodological procedures, which can help with dealing with information and photograph collections. / Mestre

This thesis explores the significance of gender as an overlooked element of context in understanding the provenance of archival records. The relevance of gender to archival provenance is demonstrated through a case study analysis of the gendered contexts of record creation, use, and meaning. The analysis is grounded in an examination of the archival photographic and textual records of Mary Schäffer Warren, an amateur photographer, traveller, and explorer of the Canadian Rocky Mountains during the years 1888 and 1939. This thesis argues that gender is an important context in a record’s provenance providing nuanced understandings of socio-cultural relations and processes of record creation, use, and meaning. Gender as context further empowers the principle of provenance by more fully reflecting how and why records are created which accordingly allows archivists to appraise, acquire, and describe records in ways more sensitive to gender as a socio-cultural reality.

This study is, primarily, a presentation of a "re-exploration" of the physiography and vegetation of a large portion of Northern Ontario. At the same time, it serves as an illustration of a method of multiple survey through the use of aerial photographs.
