This dissertation explores the contribution to opera in South Africa by The Black Tie Ensemble. The research follows a qualitative research design. It is a historical case study which is conducted against an interpretivist philosophical perspective. Data were collected through interviews conducted with prominent role-players in The Black Tie Ensemble and through various articles from newspapers and magazines. From the data collected, specific themes crystallized; the impact of performance and training opportunities flourished during the twelve years of the existence of this unique programme, the development of singers and sponsorship to the arts contributed significantly to the success or failure of this phenomenon and outreach programmes introduced the genre to the broader community. Recommendations from this study could lead towards the planning and guidance of sponsorships for similar programmes in the future and indicate the need for more training facilities of young singers throughout the country, whilst gaining performance experience in a theatre. Such training and experience could ensure a future career in singing and hence job creation. / MA (Musicology), North-West University, Potchefstroom Campus, 2015

Several reinforced concrete bent caps (deep beams) in Texas have developed significant diagonal cracks in service. The cracking in two bent caps was so extensive that costly retrofits were implemented to strengthen the structures. Strut-and-tie modeling is currently recommended in most U.S. design specifications for the design of reinforced concrete bent caps and deep beams. Designers have expressed concerns with the lack of clarity and serviceability-related considerations in strut-and-tie model design provisions. Due to concerns with strut-and-tie modeling design provisions and field problems of in-service bent caps, TxDOT Project 5253 was funded. Several tasks conducted within Project 5253 are addressed in this dissertation. The effects of minimum web reinforcement and member depth on the strength and serviceability behavior of deep beams are presented. The transition between deep beam shear capacity and sectional shear capacity near a shear-span-to-depth (a/d) ratio of 2 is addressed. A service-load shear check to limit diagonal cracking in service is outlined. Lastly, a simple chart that correlates the maximum width of diagonal cracks in a deep beam to its residual capacity is developed. To accomplish the objectives of Project 5253, thirty-seven tests were conducted on reinforced concrete beams with the following cross-sectional dimensions: 21”x23”, 21”x42”, 21”x44”, 21”x75”, and 36”x48.” The specimens were loaded with a/d ratios of 1.2, 1.85, and 2.5. The test specimens are among the largest reinforced concrete deep beams in the literature. To supplement the findings of the experimental program, a database of deep beam test results was compiled. Entries in the database that lacked sufficient information and that did not meet established cross-sectional size or web reinforcement criteria were filtered from the database. The use of the database in conjunction with the experimental program enabled each objective to be addressed from both broad and specific viewpoints. Several recommendations for improving the strength and serviceability design of deep beams are presented including a minimum web reinforcement requirement, provisions to ease the transition between calculated deep beam and sectional shear capacity, and a design check to limit diagonal cracking in service. / text

We give a short introduction to various concepts related to the theory of p-harmonic functions on Rn, and some modern generalizations of these concepts to general metric spaces. The article Björn-Björn-Lehrbäck [6] serves as the starting point of our discussion. In [6], among other things, estimates of the variational capacity for thin annuli in metric spaces are given under the assumptions of a Poincaré inequality and an annular decay property. Most of the parameters in the various results of the article are proven to be sharp by counterexamples at the end of the article. The main result of this thesis is the verification of the sharpness of a parameter. At the center of our discussion will be a concrete metric subspace of weighted Rn, namely the so-called weighted bow-tie, where the weight function is assumed to be radial. A similar space was used in [6] to verify the sharpness of several parameters. We show that under the assumption that the variational p-capacity is nonzero for any ball centered at the origin, the p-Poincaré inequality holds in Rn if and only if it holds on the corresponding bow-tie Finally, we consider a concrete weight function, show that it is a Muckenhoupt A1 weight, and use this to construct a counterexample establishing the sharpness of the parameter in the above mentioned result from [6].

Esta pesquisa realiza a análise do comportamento estrutural de blocos rígidos de concreto armado sobre duas estacas submetidos à ação de força vertical centrada, com pilares de seções quadradas e retangulares e diferentes taxas de armaduras de pilares. Nestes elementos utilizam-se o método das Bielas e Tirantes para o projeto estrutural, mas normalmente não se considera a influência da seção geométrica dos pilares e suas taxas de armadura no projeto do bloco. Apresenta-se um estudo experimental de doze modelos de blocos sobre duas estacas, na escala 1:2. Foi desenvolvida uma análise numérica tridimensional e não linear, pelo método dos elementos finitos, com o auxílio de um programa de computador. Com a análise experimental e numérica foi investigada a distribuição do fluxo das tensões principais de compressão e tração nos modelos e constataram-se diferenças na transmissão de forças para os blocos quando se altera a taxa de armadura e a seção transversal dos pilares. Esta constatação modifica o modelo de Biela e Tirante inicialmente adotado. As deformações em armaduras construtivas complementares também foram estudadas possibilitando o entendimento do modelo estrutural. Um modelo de Bielas e Tirantes para blocos sobre estaca com pilares alongados foi proposto. / This research presents an analysis of the rigid two-pile caps structural behavior. The models were subjected to force action centered and supported columns with different rate of armor and square and rectangular cross sections. These elements can be rigid or flexible, rigid pile-caps can be sized using the Method of Strut and Tie. In most cases the Method of Strut and Tie and the influence of column reinforcement are not considered in the pile-cap´s structural projects. This research presents an experimental investigation of two-pile caps with the objective of improve criteria structural projects. Twelve rigid two-pile caps were builded using 1:2 scaled models. Three-dimensional numerical analyses using software based on element finite method (FEM) were developed considering the reinforced concrete nonlinear behavior. Using results of experimental analysis and numerical analysis an investigation of the flow distribution of the principal stresses of compression and tension in the models was performed, differences in the transmission of forces to the pile-caps, when changing the reinforcement ratio and the cross section of the columns, were detected. The initial model of strut and tie may be modified due to results. The understanding of the structural model was also possible by analysis of the stirrups and upper constructive reinforcement stress-strain behavior. A strut and tie model for pile-caps with an elongated rectangular column was proposed.

A avaliação ecotoxicológica dos sedimentos dos reservatórios de Barra Bonita e Salto Grande foi realizada através de testes de toxicidade aguda e crônica com o sedimento total e o solubilizado, com os organismos-teste Chironomus xanthus, Daphnia similis, Ceriodaphnia dubia, Vibrio fisheri e Spirillum volutans, além de análises físicas (pH, EH e \'O IND.2\') e químicas (fósforo, nitrogênio, carbono orgânico total, sulfetos e amônia e metais potencialmente disponíveis). A concentrações médias de matéria orgânica e fósforo obtidas para os sedimentos dos reservatórios de Barra Bonita e Salto Grande foram elevadas, e condizentes com a carga de matéria orgânica e com as baixas concentrações de oxigênio dissolvido e de potencial redox. Em relação aos metais, os resultados revelaram que, para o reservatório de Barra Bonita, eles podem estar influenciando a toxicidade detectada através dos testes de toxicidade. Em Salto Grande, os resultados indicaram que os sulfetos estão atuando como fase controladora dos metais, mantendo-os indisponíveis nos sedimentos. Para esse reservatório a principal causa da toxicidade foi a acidez. O estudo de Avaliação e Identificação da Toxicidade realizado com as amostras de sedimento dos reservatórios de Barra Bonita, Salto Grande e Rasgão mostrou que os possíveis compostos tóxicos responsáveis pela toxicidade são metais (Barra Bonita); amônia (Salto Grande e Rasgão); compostos ácidos voláteis e compostos orgânicos não iônicos (Rasgão). O tratamento com a resina zeolita foi eficiente na remoção da amônia e redução da toxicidade do sedimento do reservatório de Rasgão, confirmando dessa forma, a amônia como o principal composto tóxico. O estudo de Avaliação e Identificação da Toxicidade deve ser incorporado nos programas de controle, monitoramento e gestão dos recursos hídricos, devido a importância da identificação dos compostos responsáveis pela toxicidade. / An ecotoxicological evaluation of the sediments of Barra Bonita and Salto Grande reservoirs was performed by carrying out acute and chronic toxicity tests with both the total sediment and elutriate using Chironomus xanthus, Daphnia similis, Ceriodaphnia dubia, Vibrio fisheri and Spirillum volutans as test-organisms, as well as physical (pH, EH e \'O IND.2\') and chemical analysis (phosphorus, nitrogen, total organic carbon, sulphide, ammonium and potentially available metals). The mean concentrations of organic matter and phosphorus obtained for the sediments of Barra Bonita and Salto Grande reservoirs were high and in agreement with the organic matter loading, low dissolved oxygen concentrations and redox potential. In relation to metals, the results revealed that in Barra Bonita reservoir they might be responsible for the toxicity detected. For Salto Grande, the results indicated that sulphides act as metal controlling phase keeping them unavailable in the sediments. The main cause of the toxicity in this reservoir was acidity. The Toxicity Identification and Evaluation (TIE) carried out with the sediments of Barra Bonita, Salto Grande and Rasgão have shown that the probable toxic compounds responsible for toxicity are metals (Barra Bonita); ammonium (Salto Grande and Rasgão); volatile acid compounds and non-ionic compounds (Rasgão). The treatment with zeolite was efficient in removing ammonium and reducing toxicity in the sediment of Rasgão reservoir, thus confirming ammonium as the main toxic compound. The Toxicity Identification and Evaluation approach must be incorporated in the control, monitoring and management of water resources, due to the relevance of identifying the compounds responsible by the toxicity.

A pesquisa teve como objetivo analisar e discutir o comportamento de blocos de concreto armado sobre duas estacas submetidos à ação de força centrada e excêntrica. Desenvolveu-se uma análise numérica tridimensional não-linear de blocos de concreto armado sobre duas estacas. A análise numérica levou em consideração a fissuração do concreto e a influência das armaduras no comportamento estrutural dos blocos. Por meio da análise numérica, foi possível perceber o comportamento e a forma geométrica das bielas de compressão, com isso, obteve-se melhor entendimento do modelo de bielas (escoras) e tirantes aplicado a blocos de concreto armado sobre duas estacas. A geometria observada nos modelos numéricos analisados preliminarmente difere da usualmente sugerida por vários autores. Realizou-se investigação experimental de blocos, com o fim principal de observar, de modo mais abrangente, a geometria das bielas de compressão. A instrumentação foi posicionada nas faces dos blocos com extensômetros espaçados de modo a ocuparem boa parte da largura e, conseqüentemente, indicarem as suas geometrias. A análise experimental de blocos sobre duas estacas submetidos à ação de força excêntrica permitiu observar o comportamento das bielas e tirantes que diferem dos observados quando a força é centrada. Também foi analisada a eficiência dos ganchos das barras de aço que compõem os tirantes, verificando-se que os ganchos podem ser omitidos sem prejuízo da segurança estrutural dos blocos. Em função dos resultados obtidos por meio das análises experimental e numérica desenvolveram-se modelos de bielas e tirantes aplicados a blocos sobre duas estacas / The research had as objective to analyze and to argue about the behavior of two pile caps submitted to the action of a centered and eccentric load. A nonlinear three-dimensional numerical analysis of two pile caps was developed. The numerical analysis included the cracking and the influence of the reinforcement in the structural behavior of the pile caps. By the numerical analysis, it was possible to perceive the behavior and the geometric form of the strut, with this understand the model strut-and-tie applied to the two pile caps. The geometry observed in the numerical models analyzed at first differs from the usually suggested by some authors. This project realized experimental tests of piles caps to observe the geometry of the struts. The instrumentation was located in the faces of the pile caps with spaced strain-gages in order to occupy good part of the width and, consequently, indicate its geometry. The experimental analysis of two pile caps submitted to the eccentric load allowed the behavior observation of the strut and tie that differ from the one observed when the load was centered. Also the efficiency of the hooks of the reinforced bar was analyzed, therefore, in the experimental analysis of pile caps already developed, it was verified that the hooks can be omitted without damage of the structural security of the pile caps. For treating the procedure defined in the project, and taking advantage of the experimental analysis realized, it was understood that this requirement can be analyzed and that the results will bring benefits to the project. In function of the results obtained through the experimental and numeric analysis strut-and-tie models were developed to be applied in two pile caps

As notorious follower of Freud, Lacan started from the progress and impasse made by the psychoanalysis creator in this field. Freud's main contribution is on thinking that the psychosis is not only a pathology and that it is another way of psychic organization. Nevertheless, Freud did not idealize a clinical treatment for the psychoses, but he did not desist from producing a theory about the issue, in private on some articles and on his study about the book Memoirs of My ervous Illness by Daniel Schreber. Lacan, still affiliated with psychiatry, on his doctoral thesis On Paranoia and Its Relationship to Personality (1932), starts from the concept that there would be a human sense in psychosis which had been left aside by the psychiatry and that it would be necessary to retake this concept, thinking the psychogenesis dimension of paranoia symptoms. Affiliated with psychoanalysis, Lacan formulates the hypothesis that in psychosis there would be a foreclosure of a primordial signifier, what would lead to another organization of the symbolic register. Based on Freud and searching for the human sense, Lacan brought from the surrealistic movement and from philosophy, that the dimension of the subject in psychosis is the bet which allows it to be seen over and above psychiatric dungeons. Finally, we propose that the movements of effort for the inclusion of the psychotic should take into account the dimension of the subject in psychosis, because they should participate actively in their treatment. Therefore, the exit would be to think the dimension of the subject and its particularity in the case of psychosis, after all he made his choice for this structure. We concluded, herewith, that retaking these psychosis theory fundamental concepts allows a contribution to the efforts for social inclusion of the psychotic subject / A presente pesquisa pretende fazer a construção do conceito de sujeito psicótico até o seminário III As psicoses (1955-1956) de Jacques Lacan, psicanalista francês que propôs uma nova forma de pensar a questão do sujeito. Como notório seguidor de Freud, Lacan partiu dos avanços e dos impasses que o criador da psicanálise fez nesse campo. A principal contribuição de Freud está em pensar que a psicose não é apenas uma patologia e sim outra forma de organização psíquica. Porém, Freud não idealizou um tratamento clínico para as psicoses, mas não deixou de produzir uma teoria sobre o assunto, em particular em alguns artigos e no seu estudo sobre o livro Memórias de um Doente dos ervos de Daniel Schreber. Lacan, ainda filiado à psiquiatria, em sua tese de doutorado Da psicose paranoica em suas relações com a Personalidade (1932), parte de uma concepção de que haveria na psicose um sentido humano que a psiquiatria havia deixado de lado e que seria necessário retomar essa concepção, pensando a dimensão da psicogênese dos sintomas da paranoia. Filiado a psicanálise, Lacan formula a hipótese que na psicose haveria uma foraclusão de um significante primordial, que provocaria uma outra organização do registro simbólico. Apoiado em Freud e na busca do sentido humano, que Lacan trouxe do movimento surrealista e da filosofia, a dimensão do sujeito na psicose é a aposta que permite enxergá-la além dos calabouços psiquiátricos. Finalmente, propomos que os movimentos de luta de inclusão do psicótico deva levar em conta a dimensão do sujeito na psicose, pois esses devem participar ativamente do seu tratamento. Para tal, a saída seria pensar a dimensão do sujeito, e sua particularidade no caso da psicose, afinal ele fez sua escolha por essa estrutura. Concluímos, com isso, que a retomada desses conceitos fundamentais da teoria da psicose permite uma contribuição às lutas de inclusão social do sujeito psicótico

Its social relevance lies at the interfaces of the interdisciplinary knowledge of Psychology, Psychoanalysis and Law, marking its specificity in the psychoanalytic field in the area of Public Health, whose social responsibility it to sustain an ethical-political position of psychological diagnosis, at the tactical and strategic levels, as regards the construction of the social bond of adolescents in situations of vulnerability. The overall goal is to build an ethical-political diagnostic mode that allows the subject, through the narrative, to constitute a singular dimension of the social event. The methodological investigation process was based on psychoanalysis in extension of Lacanian orientation in order to understand the object of knowledge in its ethical-political dimension. Territoriality was bounded by the Institution CREAS and eight teenagers were chosen, and of these, two for analysis of the case institutional politicalclinical. The procedure was carried out by visiting the Fundação Casa, the Institution CREAS observation, analysis of institutional history and interviews articulated under transfer with the memorial of the technical staff (psychologists and social workers), besides the institutional political-clinical case analysis of the teenagers A. e R.In analyzing the results, we could conclude that delinquency is the effect of the unfolding of a social scene that embodies the subject and identifies the acts, being one of the elements that contributes to the institutionalization of the symptom with the production of relapsing.The social, psychological and political vulnerability of this situation has the effect of psychologization of social ties in the individual experience, operated by a capitalist discourse through instruments that do not take into account the context the experience had been built, in an attempt to objectify the subject, turning him into a Thing subject to disubjectivation, a gadget subject. In analyzing the cases of A. e R. it was possible for both subjects, in a unique way, to (re) situate themselves and produce anOther dimension before the social event. The ethical-political psychological diagnosis as a strategy of discourse intervention can operate modes of welcoming suffering by creating new outlets inventing answers to address the malaise of our young and, with the requirements of the contemporary master, producing effects in the construction of the social bond / O problema de pesquisa deste trabalho é o impasse teórico-prático de como diagnosticar o sujeito na sua relação com o contexto de produção sociopolítico e seus efeitos discursivos na construção do laço social. Sua relevância social diz respeito às interfaces do saber interdisciplinar da Psicologia, da Psicanálise e do Direito, marcando sua especificidade no campo psicanalítico, na área da Saúde Pública, cuja responsabilidade social é sustentar uma posição ético- política do diagnóstico psicológico, nos níveis táticos e estratégicos, no tocante à construção do laço social, do adolescente em situação de vulnerabilidade.O objetivo geral é construir um modo de diagnóstico ético-político que possibilite ao sujeito, através da narrativa, constituir uma dimensão singularizável do acontecimento social. O processo de investigação metodológico fundamentouse na psicanálise em extensão de orientação lacaniana, buscando compreender o objeto do conhecimento em sua dimensão ético-política. A territorialidade foi delimitada pela Instituição CREAS, sendo escolhidos oito adolescentes para entrevista, dois dos quais para análise do caso institucional clínico-político. O procedimento incluiu visita à Fundação Casa, observação da Instituição CREAS, análise da história institucional e das entrevistas articuladas sob transferência com o memorial da equipe técnica (psicólogos e assistentes sociais), além da análise dos casos institucionais clínico-políticos dos adolescentes A.e R. Na análise dos resultados pode-se concluir que a delinquência advém do desdobramento de uma cena social que se corporifica no sujeito e o identifica em actos, um dos elementos que contribuem para a institucionalização do sintoma com a produção do reincidente. A vulnerabilidade social, psicológica e política dessa situação produz o efeito da psicopatologização do laço social na experiência individual, operada pelo discurso capitalista através de instrumentos que não levam em consideração o contexto em que a experiência fora construída. Na tentativa de objetivação do sujeito, transforma-o numa Coisa dessubjetivável, num sujeito gadget. Na análise dos casos A.e R. foi possível para ambos os sujeitos, de modo singular, (re)situarem-se e produzirem uma Outra dimensão diante do acontecimento social. O diagnóstico psicológico ético-político como estratégia de intervenção discursiva pode operar modos de acolher o sofrimento criando novas saídas e inventando respostas para lidar com o mal-estar dos nossos jovens e, com as exigências do mestre contemporâneo, produzindo efeitos na construção do laço social

O Litoral Norte de São Paulo é uma região pouco impactada e com elevada sensibilidade ecológica e que reúne perspectivas de grande crescimento econômico com novas instalações de empresas ligadas à exploração do PRÉ-SAL. O presente estudo tem como objetivo analisar a toxicidade dos sedimentos dos Municípios de Ubatuba e Caraguatatuba com os procedimentos da Avaliação e Identificação da Toxicidade (AIT), somente a fase I, proposto pela USEPA (1991; 2007). O ensaio de toxicidade crônico de desenvolvimento embriolarval do ouriço do mar Lytechinus variegatus. Foi extraída a água intersticial dos sedimentos, coletados em quatro enseadas, pelo método de sucção descrito por Winger & Lasier (1991), sendo dois pontos de coleta na Enseada de Ubatuba - Perequê-Açu e Itaguá, um na Enseada do Flamengo, um na Enseada do Mar Virado e uma na Enseada de Caraguatatuba. A AIT evidenciou como agente causador da toxicidade, de modo geral, os compostos pH dependentes e dos metais. As amostras do Perequê-Açu e de Caraguatatuba apresentaram toxicidade em todas as amostras analisadas, as demais amostras não presentaram nenhuma relação entre a toxicidade e a sazonalidade. / São Paulo north coast is a poor impacted region and with high ecological sensitivity which gathers perspectives of great economic growth with new facilities related to the operation of the Pre-Salt companies. The aim of the present study is to analyze the toxicity of sediments from the municipalities of Ubatuba and Caraguatatuba with the procedures of the Toxicity Identification Evaluation (TIE), only the phase I, proposed by USEPA (1991, 2007). The test of chronic toxicity of embriolarval development of sea urchin Lytechinus variegates. Pore water was extracted from the sediments collected in four bays, by the suction method described by Winger & Lasier (1991), being two collection points in Ubatuba Bay - Perequê-Açu and Itaguá, one in Flamengo Bay, one the Mar Virado Bay and one in Caraguatatuba Bay. The TIE evidenced as a causative agent of toxicity, in general, the compounds of pH dependent and of metals. The samples of Perequê-Açu and Caraguatatuba showed toxicity in all samples, the other samples showed no relationship between toxicity and seasonality.
