No. of bitstreams: 1 ElianaMC.pdf: 1221443 bytes, checksum: c2ecaef1ae772fb4d8e14dd13d82d037 (MD5) Previous issue date: 2007-06-02 / The potential market of the metropolitan area of Salvador accounts for the estimated consumption of roughly 800 million horizontally perforated extruded clay bricks a year. The growing demand of consumers along with the competitiveness of the structural ceramic sector has driven forward a number of recent efforts and investments towards improving the quality of structural ceramics. In this scenario, the present study focused on sampling and evaluating the conformity of 8-hole horizontally perforated extruded clay bricks manufactured by different plants (A, B and C) in the metropolitan area of Salvador. In addition, representative clay and sandy-clay materials were collected from each plant and characterized by conventional physical, chemical and mineralogical techniques. Finally, experimental compositions designated as A, B and C, according to the source, were prepared by mixing different contents of the raw materials collected in the plants, fired at different temperatures and characterized. The results revealed a series of non conformities regarding ABNT guidelines. The characterization of raw materials revealed the presence of kaolinite and ilite in concentrations ranging from 64 to 90 wt.% along with free quartz (10 - 25%). The sandy-clay samples consisted basically of kaolinite. All raw materials depicted low contents of organics, amorphous constituents, alkaline oxides and feldspar. An analysis of the firing behavior of all different ceramic compositions revealed that the linear contraction of composition A was rather significant considering the temperature range evaluated, and it justifies the significant dimensional non conformity that was shown by bricks made with the ceramic A / O mercado potencial de cer?mica estrutural na regi?o metropolitana de Salvador ? respons?vel pelo consumo de mais de 800 milh?es de pe?as/ano. Com um com?rcio cada vez mais exigente e competitivo torna-se necess?rio que as ind?strias ceramistas invistam em a??es que visem aperfei?oar a qualidade de seus produtos. O objetivo desse estudo foi avaliar o ?ndice de conformidade de blocos cer?micos e caracterizar a mat?ria-prima. Foram empregadas as normas ABNT para an?lise de conformidade de blocos cer?micos em tr?s ind?strias (A, B e C) da Regi?o Metropolitana do Salvador, bem como t?cnicas para caracteriza??o qu?mica, f?sica e mec?nica das mat?rias-primas e formula??o e an?lise das massas. Com base nos resultados alcan?ados pode-se concluir que os blocos cer?micos fabricados pelas ind?strias pesquisadas n?o apresentam conformidade com as normas t?cnicas brasileiras. Os argilominerais encontrados nas mat?rias-primas estudadas (massas A, B e C) foram a caulinita e a ilita que ficaram entre 64 a 90% e o teor de quartzo livre entre 10 e 25%. Os arenosos s?o predominantemente argilas caulin?ticas. Os materiais caracterizados apresentaram baixa concentra??o de materiais amorfos, baixo teor de ?xidos alcalinos e, conseq?entemente, concentra??es muito baixas de feldspatos. A an?lise das curvas de gresifica??o das massas demonstra que a inclina??o da curva de retra??o linear ? mais acentuada para a massa A, na faixa de temperatura estudada, e justifica a significativa n?o conformidade dimensional verificada nos blocos produzidos pela cer?mica A

MÉTODOS ESTATÍSTICOS APLICADOS À AVALIAÇÃO DA QUALIDADE DA MATÉRIA-PRIMA E CLASSIFICAÇÃO DOS FORNECEDORES DE UMA INDÚSTRIA DE LATICÍNIOS / STATISTICAL METHODS APPLIED TO THE QUALITY ASSESSMENT OF RAW MATERIALS AND CLASSIFICATION OF SUPPLIERS OF A DAIRY INDUSTRY

Seidel, Enio Júnior 20 February 2009 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The aim of this study was to evaluate the quality of raw materials delivered by suppliers of a dairy industry based on physicochemical specifications. The development of the work consisted of literature research, followed by a case-study with descriptive approach involving variables of quantitative nature. In order to develop the analysis of data, the following statistical techniques were used: Exploratory analysis of data (used to evaluate the consistency of the collected data and to verify their behavior in relation to variability and normality), non-parametric methods (used to compare periods and collection patterns in relation to the behavior of the variables), CEP (used through the construction of control charts for attributes based on the specifications of the variables), multivariate analysis (used through the factorial analysis in the construction of indexes for the classification of suppliers). Two stages were observed in the development of the study. In the first stage, an analysis on the quality of milk based on the acidity determination was conducted. In the second stage, the analysis of the quality of raw materials was conducted using only lots with appropriate acidity values and considering the other physicochemical variables. The results obtained in the first stage were used to observe that most of the lots were produced according to quality standards established for acidity. For the comparison of the milk collection patterns, in general, pattern 1 obtained better performance in all seasons. In the second stage of the analysis, the results showed that suppliers presented lower percentage of milk lots with appropriate specifications for the percentage of water and density. Moreover, considering the comparison between the collection patterns in winter, it was possible to verify that patterns 2 and 3 had the best performance in the quality indicator. Considering the spring season, it was found that standard 1 presented the best performance. In addition, comparing the collection standards in the summer, it was found that standard 2 obtained the best performance. Through the control charts applied, it was possible to perceive that the process was out of control in the three periods mainly due to problems with the specification of the percentage of water and density. Finally, with the aid of the factorial analysis, indexes for the classification of suppliers were calculated based on physicochemical variables. / A presente pesquisa buscou avaliar a qualidade da matéria-prima entregue pelos fornecedores de uma indústria de laticínios com base nas especificações físico-químicas. O desenvolvimento do trabalho constituiu-se de pesquisa bibliográfica, seguida de estudo de caso com abordagem de cunho descritivo, envolvendo variáveis de natureza quantitativa. Para desenvolver as análises dos dados foram utilizadas as seguintes técnicas estatísticas: Análise exploratória de dados (foi utilizada para avaliar a consistência dos dados coletados e verificar seu comportamento quanto à variabilidade e normalidade); Métodos não-paramétricos (serviram para comparar períodos e rotas de coleta quanto ao comportamento das variáveis); CEP (foi utilizado através da construção de gráficos de controle para atributos com base nas especificações das variáveis); Análise multivariada (utilizada através da análise fatorial na construção do índice para classificação dos fornecedores). No desenvolvimento do estudo foram respeitadas duas etapas. Na primeira etapa foi realizada uma análise sobre a qualidade do leite com base na determinação da acidez. Na segunda etapa foi desenvolvida a análise da qualidade da matériaprima utilizando somente os lotes com medidas adequadas de acidez e considerando as demais variáveis físico-químicas. Com os resultados obtidos na primeira etapa da análise foi possível observar que a maioria dos lotes produzidos estava de acordo com os parâmetros de qualidade estabelecidos para a acidez. Em relação a comparação das rotas de coleta do leite, de modo geral, a rota 1 obteve melhor desempenho em todas as estações. Na segunda etapa da análise os resultados mostraram que os fornecedores apresentaram baixos percentuais de lotes de leite adequados às especificações para o percentual de água excedente e para a densidade. Além disso, considerando a comparação entre as rotas de coleta, no inverno, foi possível verificar que as rotas 2 e 3 tiveram melhor desempenho no indicador de qualidade. Considerando a estação da primavera, percebeu-se que a rota 1 obteve melhor desempenho. E, realizando-se a comparação das rotas de coleta no verão, verificou-se que a rota 2 obteve melhor desempenho. Pelos gráficos de controle aplicados foi possível perceber que o processo estava fora de controle nos três períodos, devido, principalmente, a problemas com as especificações do percentual de água excedente e da densidade. Por fim, com auxilio da análise fatorial, foram calculados índices para classificação dos fornecedores com base nas variáveis físico-químicas.

"SNOW IS A STRANGE WHITE WORD". POESIA E PITTURA NELL'OPERA DI ISAAC ROSENBERG, WAR POET (1890-1918) / "Snow is a strange white word". Poetry and Painting in the Works of Isaac Rosenberg, war poet (1890-1918)

MAGGIONI, ERICA 19 September 2017 (has links)
La tesi studia l’opera del war poet inglese Isaac Rosenberg (1890-1918) con l’obiettivo principale di analizzare l’influenza della sua formazione pittorica sulla produzione poetica, un aspetto che, seppur generalmente riconosciuto, è stato poco approfondito dalla critica. I primi tre capitoli esaminano il contesto sociale, culturale e artistico in cui Rosenberg visse prima di arruolarsi nell’esercito; in particolare, viene presentata la comunità ebraica dell’East End di Londra, il suo coinvolgimento nella Prima Guerra Mondiale, la scena artistica di inizio ventesimo secolo. Lo studio considera anche la scuola d’arte da lui frequentata, la Slade, la sua limitata produzione pittorica e le sue riflessioni di estetica, contenute nelle lettere e nella prosa. Il quarto capitolo, fulcro della tesi, propone un’analisi dei testi poetici che mira a evidenziare come il poeta abbia sfruttato l’esperienza di pittore nella scrittura, specialmente nella war poetry. Tra le strategie identificate, vi sono l’utilizzo simbolico dei colori, l’imagery relativa a luce e buio, l’adozione di una particolare prospettiva, la commistione tra astratto e concreto. Tali tecniche vengono lette come tentativi di rispondere alla difficoltà di rappresentazione e comunicazione dell’esperienza bellica. / The thesis studies the works of English war poet Isaac Rosenberg (1890-1918) with the main aim of analysing the influence of his pictorial training on his poetic production, an aspect which has been generally acknowledged, but scarcely investigated by critics. The first three chapters examine the social, cultural and artistic context in which Rosenberg lived before enlisting in the army; in particular, the focus is on the Jewish community of London’s East End, the involvement in the First World War, and the art scene of the early Twentieth century. The study also considers the art school he attended, the Slade, his limited pictorial production, and his thoughts on aesthetics, as included in the letters and prose. The fourth chapter, core of the thesis, proposes an analysis of the poems which aims to show how Rosenberg exploited his experience as a painter in his writing, especially in the war poetry. Among the identified strategies are the symbolic use of colours, the imagery related to light and shadow, the adoption of a particular perspective, the fusion of abstract and concrete. These techniques are seen as attempts to respond to the difficulty of representing and communicating war experience.

El uso equívoco de los términos "formal" y "material" en las Meditaciones metafísicas

Caravedo Durán, Joan 13 May 2014 (has links)
La noción de idea en Descartes es uno de los términos trasversales en el conjunto de su obra y muestra una nueva consideración al respecto de lo anímico y de su relación con lo material. Procurar negar el rol fundamental de las ideas cartesianas nos dejaría sin la capacidad de comprender una de las obras más importantes de este autor, en la cual nos centraremos en el presente trabajo: Meditaciones metafísicas. La noción de “idea”, que recibe un tratamiento detallado recién en la tercera de las meditaciones, nos sirve como elemento fundamental para la comprensión del conjunto del texto, al punto que incluso las dudas escépticas de la primera meditación pueden ser vistas como el despliegue de un camino hacia el descubrimiento del terreno del cogito, región de una clase de los entes puramente espirituales, que son las ideas

The Girl Gang: Women Writers of the New York City Beat Community

Petrich, Tatum January 2012 (has links)
The Girl Gang: Women Writers of the New York City Beat Community seeks to revise our understanding of the Beat community and literary tradition by critically engaging the lives and work of five women Beat writers: Diane di Prima, Joyce Johnson, Hettie Jones, Carol Bergé, and Mimi Albert. This dissertation argues that, from a position of marginality, these women developed as protofeminist writers, interrogating the traditional female gender role and constructing radical critiques of normative ideas in fiction and poetry in ways that resisted the male Beats' general subordination of women and that anticipated the feminist movement of the late 1960s and 1970s. A project of recovery and criticism, The Girl Gang provides literary biographies that explore how each writer's experience as a marginalized female writer within an otherwise countercultural community affected the development of her work; it also analyzes a range of works (published and unpublished texts from various genres, written from the early 1950s through the turn of the twenty-first century) in order to illustrate how each writer distinctively employs and revises mainstream and Beat literary and cultural conventions. The dissertation's critical analyses examine each writer's engagement in various literary, cultural, and social discourses, drawing attention to their incisive and provocative treatment of thematic issues that are central to the postwar countercultural critique of hegemonic norms --including fundamental Beat questions of identity, authenticity, and subjectivity-- and that are developed through experimentation with literary conventions. Ultimately, The Girl Gang argues that the literary achievements of the New York City women Beats collectively reconceptualize the prevailing notion of the Beat community and canon. / English
