This is because amounts of residue are generated which vary in type and danger level. The soil contamination by non aqueous liquid phase mixtures, specifically hydrocarbon petroleum has been a reason for great concern, mainly the aromatic and polycyclic aromatic, which present risk to human health due to its carcinogenic and mutagenic character. The Advanced Oxidative Processes (AOP) are efficient technologies for destruction of organic compounds of difficult degradation and, often, they are present in low concentrations. They can be considered clean technologies, because there is no formation of solid by-products or the transfer of pollutor phases. This work focuses on the study of the degradation of petroleum industrial waste, by Advanced Oxidation Processes. Treatments tackling petroleum residues, contaminated soil, and water occurring in the production of petroleum reached the following Polycyclic Aromatic Hydrocarbons (PAH) degradation levels: solid residues 100% in 96 treatment hours; water residue - 100% in 6 treatment hours; soil contamination (COT degradation) - 50.3% in 12 treatment hours. AOP were effective in dealing with petroleum residues thus revealing themselves to be a promising treatment alternative / A ind?stria de petr?leo lida com problemas de dif?cil solu??o em rela??o ?s atividades voltadas para a prote??o ambiental, devido ? gera??o de res?duos de diversos tipos e n?veis de periculosidade. A contamina??o do solo por compostos de fase l?quida n?o aquosa, especificamente os hidrocarbonetos de petr?leo tem sido motivo de preocupa??o, principalmente os arom?ticos e poliarom?ticos, apresentam risco ? sa?de humana devido a seu car?ter carcinog?nico e mutag?nico. Os Processos Oxidativos Avan?ados (POA) s?o tecnologias eficientes para destrui??o de compostos org?nicos de dif?cil degrada??o biol?gica e, muitas vezes, presentes em baixas concentra??es. Podem ser consideradas tecnologias limpas, pois n?o h? a forma??o de subprodutos s?lidos e nem a transfer?ncia de fase dos poluentes. O objetivo desse trabalho foi estudar a degrada??o de res?duos da ind?stria de petr?leo, por Processos Oxidativos Avan?ados. Foram realizados tratamentos de borra de petr?leo, solo contaminado com petr?leo e ?gua de produ??o de petr?leo alcan?ando uma degrada??o de Hidrocarbonetos Polic?clicos Arom?ticos (HPA) de 100 % em 96 horas de tratamento para a borra, 100% em 6 horas de tratamento para ?gua de produ??o de petr?leo e uma degrada??o de Carbono Org?nico Total (COT) de 50,3% em 12 horas de tratamento para o solo contaminado com petr?leo. Os POA foram eficientes no tratamento de res?duos de petr?leo apresentando-se como uma alternativa promissora no tratamento desses res?duos

Brazil has a semiarid, considered the most problematic of the world, either by pressure from physical factors, whether as a result of misguided public policies, has over time been suffering from the consequences of a deterioration that expands over the years. Methodologies, that amidst the problems of semi-arid, come against the deteriorating local, have a good chance to be reapplied in other contexts around the world. This research, based on methodological model for analyzing environmental deterioration, introduced and examined the applicability of the methodology in the semi-arid region of Rio Grande do Norte - Brazil. Although the results provide guidelines for the introduction of underground dams, the application of the methodology was ineffective, given the high rates of forest cover that gave low values for the physical diagnosis conservationist / No mundo contempor?neo a deteriora??o das ?reas semi-?ridas do planeta tem sido foco da aten??o da m?dia e da comunidade cient?fica. O Brasil possuindo um semi-?rido, considerado o mais problem?tico do mundo, seja por press?es dos fatores f?sicos, seja como conseq??ncia de pol?ticas p?blicas equivocadas, tem ao longo do tempo sido v?tima das conseq??ncias de uma deteriora??o que se amplia com o passar dos anos. Metodologias, que em meio ? problem?tica do semi-?rido brasileiro, venham de encontro a deteriora??o local, t?m boas probabilidades de serem reaplicadas em outros contextos ao redor do mundo.

Their corpuses of study are the novels As horas nuas (1989), by the Brazilian writer Lygia Fagundes Telles; and O vento assobiando nas gruas (2002), by the Portuguese writer L?dia Jorge. The following research tries to understand how the characters from those texts deal with some love questions on the context of the contemporary narrative; it also tries to comprehend the love expression which is formed as a contradictorily fluid feeling and intensely wanted, which are important points concerning the love discourse at the present day. As a critic-comparative study, this research focuses on the problematic concerned love as a synonym of Eros, in other words, the relation between lovers, analyzed through social and philosophical perspective. Through that, this work broadens the study of two contemporary novels, and it also establish connections between the characters from those novels and the literary environment where they are placed, once it focuses on the human and social context presented in this books. The thesis ends calling attention to the dichotomy of love and death, to the image of love which grows through absence and through the longing of completeness of the human being; that is why this work sustains that the Lygia Fagundes Telles and L?dia Jorge update and materialized in their texts the plurality of contemporary love conception, which continues to be contradictory, fragmented and problematic / A tese A paz tensa da chama fugaz: a configura??o do amor no romance contempor?neo, Lygia Fagundes Telles e L?dia Jorge tem por objetivo estudar a configura??o do amor em romances contempor?neos. Como corpus de estudo selecionaram-se os romances As horas nuas (1989), da escritora brasileira Lygia Fagundes Telles, e O vento assobiando nas gruas (2002), da escritora portuguesa L?dia Jorge. O estudo busca entender como as personagens destes textos lidam com as quest?es amorosas no contexto da narrativa contempor?nea, bem como compreender a express?o do amor que se constitui enquanto sentimento contraditoriamente fluido e insistentemente buscado, quest?es caras ao discurso amoroso da contemporaneidade. De cunho cr?tico-comparativo, esta pesquisa priorizar? as problem?ticas relativas ao amor como sin?nimo de Eros, ou seja, a rela??o amorosa entre amantes, analisados por um vi?s social e filos?fico. Objetiva-se, pois, com isso, ampliar os estudos de duas obras liter?rias contempor?neas, assim como estabelecer rela??es entre as personagens dos textos estudados com o universo que as cercam, focalizando o contexto humano e social em que as hist?rias s?o representadas. Finaliza-se por observar nos textos das escritoras analisadas a dicotomia amor e morte, a imagem do amor que se alimenta da aus?ncia, e do desejo de completude do homem, defendendo a hip?tese de que as escritoras Lygia Fagundes Telles e L?dia Jorge atualizam e materializam em seus textos a pluralidade do conceito de amor contempor?neo, que continua contradit?rio, fragmentado e problem?tico

No. of bitstreams: 1 TaulliBL_DISSERT.pdf: 1150500 bytes, checksum: b3e29a8f79cd73bc29681007aa790d27 (MD5) Previous issue date: 2011-09-27 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / The discrimination learning is assessed through instrumental tasks in which the individual is rewarded for choosing one item over another. Thus, in concurrent visual discrimination of objects the animal must learn that only one of the objects will be rewarded. The concurrent visual discrimination is relatively simple, and already been observed Callithrix jacchus is able to accomplish this task. As yet wasn't seen the influence of the qualitative aspects of the rewards, in the performance of concurrent visual discrimination of objects in nonhuman primates, and as in most tests are used isolated animals, the present study had two stages: at first we had as objective to analyze the influence of the caloric value of the reward on the performance in concurrent visual discrimination of objects in isolated animals; in the second, we had the intention analyze performance of C. jacchus in realization of discrimination task in different social contexts, as well as, analyze the influence of previous experience in task performance. In the first stage (Study 1), the animals were not able to discriminate foods that presented small caloric differences . This incapacity in discriminates the rewards was responsible by generating randomness in task of concurrent visual discrimination of objects. In the second stage (Study 2), observed that, independent of social context in which the task was presented, the performance both of the experienced animals as the inexperienced animals tended to randomness. In the first case, is likely that the pattern of responses of the experienced animals is a reflection of their own performance when they were observed in isolation. In the second case, in turn, the randomness was probably due to the small number of sessions. Although present a pattern of performance similar to inexperienced individuals, we verify that the experienced animals monopolize the food consumption when they were in the presence of inexperienced individuals. This was a consequence of the experienced animals have presented lower latency the approximation of apparatus and, consequently, obtain more food. In turn, the inexperienced animals, when were in the presence of experienced, had to adopt alternative strategies to obtain food. Thus, C. jacchus is able to use the previous information he had about the task of solving their own benefit. / A aprendizagem discriminat?ria ? analisada atrav?s de tarefas instrumentais nas quais o indiv?duo ? recompensado por escolher um item ao inv?s de outro. Desse modo, na discrimina??o visual simult?nea de objetos o animal deve aprender que somente um dos objetos ser? recompensado. A discrimina??o visual simult?nea ? relativamente simples, e j? foi observado que Callithrix jacchus ? capaz de realizar essa tarefa. Como ainda n?o foi verificada a influ?ncia dos aspectos qualitativos das recompensas no desempenho da discrimina??o visual simult?nea de objetos em primatas n?o-humanos, e como na maioria dos testes s?o utilizados animais isolados, o presente trabalho apresentou duas etapas: na primeira tivemos como objetivo analisar a influ?ncia do valor cal?rico da recompensa sobre o desempenho na discrimina??o visual simult?nea de objetos em animais isolados; na segunda, tivemos o intuito analisar o desempenho de C. jacchus na realiza??o da tarefa discriminat?ria em diferentes contextos sociais, assim como, analisar a influ?ncia da experi?ncia anterior no desempenho da tarefa. Na primeira etapa (Estudo 1), os animais n?o foram capazes de discriminar os alimentos que apresentavam pequenas diferen?as cal?ricas. Essa incapacidade em discriminar as recompensas foi respons?vel por gerar aleatoriedade na tarefa de discrimina??o visual simult?nea de objetos. Na segunda etapa (Estudo 2), observamos que, independente do contexto social no qual a tarefa foi apresentada, o desempenho tanto dos animais experientes quanto dos animais inexperientes tendeu a aleatoriedade. No primeiro caso, ? prov?vel que o padr?o de respostas dos animais experientes seja um reflexo do seu pr?prio desempenho quando foram observados isoladamente. No segundo caso, por sua vez, a aleatoriedade foi devida provavelmente ao pequeno n?mero de sess?es. Apesar de apresentar padr?o de desempenho semelhante aos indiv?duos inexperientes, n?s verificamos que os animais experientes monopolizaram o consumo do alimento quando estavam na presen?a de indiv?duos inexperientes. Isso foi uma consequ?ncia dos animais experientes terem apresentado menor lat?ncia de aproxima??o do aparato e, consequentemente, obterem mais alimento. Por sua vez, os animais inexperientes, quando estavam na presen?a de experientes, tiveram que adotar estrat?gias alternativas para obter o alimento. Desse modo, C. jacchus ? capaz de utilizar a informa??o anterior que tinha sobre a resolu??o da tarefa em benef?cio pr?prio.

Com base na curva de termogravim?trica os p?s de SrMoO4 foram calcinados a 650?C.Os materiais sintetizados foram caracterizados por TG/DSC, DRX, EDX, MEV e ERD. Os par?metros de rede da estrutura cristalina foram obtidos com base no m?todo de refinamento Rietveld. Todos os padr?es de DRX foram indexados segundo a ficha JCPDS 01-085-0586, com estrutura tetragonal e grupo espacial I41/a e o par?metro residual do refinamento da estrutura variou entre 1,035 a 1,292, n?o sendo identificadas fases secund?rias e impurezas. Constatou-se a exist?ncia de diferen?as entre as intensidades relativas m?dias dos picos de difra??o de raios-x. Atrav?s de ferramentas estat?sticas, concluiu-se que a taxa de aquecimento foi a vari?vel independente que demonstrou maior influ?ncia nessa diferen?a. As analises de EDX mostraram a presen?a de desvios entre a composi??o te?rica e experimental para os elementos estr?ncio e molibd?nio; o desvio percentual variou de 0,027 a 3,67% em fun??o das condi??es de s?ntese. De acordo com as micrografias obtidas por MEV, os p?s sintetizados s?o compostos de aglomerados de part?culas, com morfologia esf?ricas irregulares e bipiramidais. De acordo com a an?lise do planejamento experimental, tendo como vari?vel dependente a energia de bandgap, os menores valores obtidos (4,18 e 4,17 eV para pH 6 e 9, respectivamente) foram as amostras calcinadas por 3h com taxa de aquecimento igual a 10?C.min-1 em compara??o aos materiais calcinados nas demais condi??es de s?nteses e os modelos estat?sticos gerados se mostraram capazes de descrever os fen?menos observados. Testes explorat?rios na fotodegrada??o da solu??o sint?tica do corante azul de metileno utilizando o material com Egap de 4,17 eV indicam que o p? testado apresenta influ?ncia na diminui??o da concentra??o do corante para os testes realizados em pH 2 e 5 obtendo aproximadamente 95% e 24% de convers?o respectivamente, e para os teste em pH 9 observou-se que a fot?lise direta ? mais efetiva na redu??o da concentra??o do corante alcan?ando em torno 67% de convers?o, por?m o processo reacional necessita ser mais estudado para melhor compreens?o dos resultados. / This work describes the 2? experimental design with center point in triplicate for the production of strontium molybdate (SrMoO4) through complexation combined Citrate/EDTA method where investigated the influence of pH (6, 7,5 and 9), time calcination (3, 4 and 5 h) and heating rate (5, 7 and 10?C min-1) in some of its chemical and physical parameters. Based on thermogravimetric curve of SrMoO4 powders were calcined at 650?C. The synthesized materials were characterized by TG/DSC, XRD, EDX, SEM and ERD. The lattice parameters of the crystal structure were obtained from the Rietveld refinement method. All the XRD patterns were indexed according to JCPDS 01-085-0586 record with tetragonal structure and space group I41/a and the residual parameter structure refinement ranged from 1.035 to 1.292, secondary phases and impurities not being identified. It was found that there are differences between the average relative intensities of the diffraction peaks of X-rays. Using statistical tools, it was found that the rate of heating was the independent variable showed the greatest influence on this difference. The EDX analysis showed the presence of deviations between the theoretical and experimental composition for strontium and molybdenum components; the percentage deviation ranged from 0.027 to 3.67% depending on the conditions of synthesis. According to the SEM micrographs, the synthesized powders are composed of agglomerates of particles with irregular and spherical morphology bipiramidal. According to the analysis of the experimental design, with the dependent variable bandgap energy, the lowest values (4.18 and 4.17 eV to pH 6 and 9, respectively) were the samples calcined for 3 hours at the same heating rate 10 C min-1 compared to the calcined material in other conditions of synthesis and the statistical models generated have been shown to describe the observed phenomena. Exploratory testing photodegradation of the synthetic solution of methylene blue dye using the material bandgap of 4.17 eV indicate that the tested powder has influence on the reduction of dye concentration for tests carried out in pH 2 and 5 getting approximately 95% and 24 % conversion respectively, and the test at pH 9 it was noted that direct photolysis is more effective in reducing the dye concentration reached around 67% conversion, but the reaction process needs more study to better understand the results.

O grotesco na cena da dança contemporânea: corpo e comunicação / The grotesque in contemporary dance scene: body and communication

Marcelus Gonçalves Ferreira 18 June 2012 (has links)
A presente dissertação se dedica a refletir sobre o corpo e o grotesco na arte e na comunicação contemporâneas. O objetivo do estudo foi investigar o grotesco na cena da dança contemporânea com o intuito de compreender como se dá a relação entre o modo de apreensão do grotesco na atualidade e o modo como ele se apresenta cenicamente. Assim, procurou-se investigar que representações da cultura contemporânea podem estar associadas às manifestações do fenômeno grotesco; como a mídia e o consumo de massa participam na disseminação desta estética; e como o corpo cênico na dança se aproxima/reflete estas representações presentes no cotidiano. O fenômeno grotesco, objeto de estudo desta pesquisa, foi investigado em duas companhias de dança: a Lia Rodrigues Companhia de Danças (RJ) e o Grupo Cena 11 de Dança (SC), onde foram observados o tratamento artístico e os dispositivos utilizados para construção do efeito corpo-grotesco nos espetáculos e o posicionamento dos artistas com o uso da estética grotesca nas obras. O embasamento teórico do estudo investiu na compreensão do fenômeno grotesco nos âmbitos histórico, estético/artístico e social e sua contextualização na contemporaneidade. Partiu-se do entendimento de que o corpo é mídia primária, "espaço" de comunicação e de linguagem e a dança cênica é um fenômeno urbano, que espelha as transformações representacionais do início deste século XXI. As abordagens teóricas de Mikhail Bakhtin sobre o realismo grotesco; de Wolfgang Kayser, sobre o grotesco romântico e os estudos de Muniz Sodré e Raquel Paiva, sobre o grotesco na comunicação contemporânea fundamentaram as discussões. Foi relevante refletir sobre as mudanças de paradigmas sociais que vêm se desenhando na atualidade, sobretudo com a influência do desenvolvimento tecnológico e midiático sobre as corporeidades e os processos de subjetivação. As qualidades fluidas e polifônicas associadas à contemporaneidade nortearam o entendimento desses novos paradigmas estéticos do corpo - atribuídos como corporeidades móveis contemporâneas - e, serviram para denominar/compreender como "grotesco líquido" a presença múltipla e volátil dos fenômenos grotescos na atualidade. / This dissertation is dedicated to reflecting on the body and the grotesque in the contemporary art and communication. The aim of this study was to investigate the grotesque in contemporary dance scene in order to understand the relationship between the way of apprehension of the grotesque nowadays and how it is presented scenically. This way, we sought to investigate representations of contemporary culture that may be associated with manifestations of the grotesque phenomenon; how the media and mass consumption take part in the dissemination of this aesthetic; and how, in the dance, the scenic body approaches/reflects these representations present in everyday life. The grotesque phenomenon, object of this research, was investigated in two dance companies: Lia Rodrigues Companhia de Danças (RJ) and Grupo Cena11 de Dança (SC), where we observed the artistic treatment and equipment used for the construction effect on body-grotesque during the performances and the point of view of the artists using the grotesque aesthetic in their works. The theoretical grounds of this study invested in understanding the grotesque phenomenon in historical fields, aesthetic/artistic and social and its contextualization in contemporaneity. This started from the understanding that the body is primary media, "space" of communication and language, and the scenic dance is an urban phenomenon that mirrors the representational transformations from the beginning of the 21st century. The theoretical approaches of Mikhail Bakhtin on the grotesque realism; Wolfgang Kayser, on the romantic grotesque and the studies of Muniz Sodré and Raquel Paiva, on the grotesque in contemporary communication grounded the discussions. It was important to reflect on the changing of social paradigms that have been molding themselves nowadays, especially with the influence of technological development and media on corporeality and subjectivity processes. The fluid and polyphonic qualities associated with contemporaneity, guided the understanding of these new aesthetic paradigms of the body - assigned as contemporary mobile corporealities - and served to denominate/understand as "liquid grotesque" the multiple and volatile presence of the grotesque phenomena today.

The current work discussed the influence of the use of a didactic sequence, made upon the M?heut model and based on the Ausubel meaningful learning theory, in the insertion of Modern and Contemporary Physics in High School, through the use of the X radiation production and emission theory as the main theme. A quantitative analysis was performed by using the Pearson's Chi-squared test to verify the likely association between the didactic sequence use and the students' educational achievement from questionnaires elaborated according to the revised Bloom taxonomy.A conceptual maps analysis was performed based on the progressive differentiation and the integrating reconciliation of concepts to verify the occurrence of a meaningful learning by the students related to the X radiation theory conceptions. The quantitative analysis outputs demonstrated a statistically significant association between the experimental classroom students' performance and the use of the educational product (Didactic Sequence), whilst the conceptual maps analysis indicated the occurrence of a meaningful learning based on the progressive differentiation and the integrating reconciliation of concepts, which validates such educational strategy developed for the teaching of Modern and Contemporary Physics during High School Years. / Este trabalho teve como objetivo central desenvolver um produto educacional (Sequ?ncia Did?tica) que possa potencializar a aprendizagem significativa de conceitos da F?sica Moderna e Contempor?nea, a partir do estudo da Teoria de Produ??o e Emiss?o de Radia??o X, no n?vel m?dio de ensino. O presente estudo discutiu a influ?ncia da aplica??o de uma sequ?ncia did?tica, constru?da com base no modelo de M?heut e fundamentada na Teoria da Aprendizagem Significativa de Ausubel, na inser??o da F?sica Moderna e Contempor?nea no n?vel m?dio, utilizando a Teoria de Produ??o e Emiss?o de Radia??o X como tema principal. Foi realizada uma an?lise quantitativa, usando o teste qui-quadrado de Pearson, para verificar a poss?vel associa??o entre a aplica??o da sequ?ncia did?tica e o rendimento dos estudantes, a partir de question?rios elaborados de acordo com a Taxonomia de Bloom revisada. Foi realizada uma an?lise de mapas conceituais com base na percep??o da diferencia??o progressiva e da reconcilia??o integradora de conceitos, para verificar a ocorr?ncia da aprendizagem significativa dos estudantes acerca dos conceitos da Teoria da Radia??o X. Os resultados da an?lise quantitativa mostraram a exist?ncia de uma associa??o estatisticamente significante entre o rendimento dos estudantes da turma experimental e a aplica??o do produto educacional (Sequ?ncia Did?tica), enquanto que a an?lise dos mapas conceituais indicou a ocorr?ncia de aprendizagem significativa, com base na diferencia??o progressiva e reconcilia??o integradora de conceitos, o que valida a estrat?gia de ensino desenvolvida para o ensino de conceitos de F?sica Moderna o Contempor?nea no Ensino M?dio.

The 1986 National Endowment for the Arts Commission: An Introspective Analysis of Two Marimba Works

Fang, I-Jen 08 1900 (has links)
The marimba is rapidly achieving greater importance as a solo percussion instrument. Solo compositions for the marimba have been commissioned and performed only in the last sixty years. The 1986 National Endowment for the Arts Solo Marimba Commission is considered one of the most important commissioning projects in the history of marimba literature. Two compositions created through this project, Velocities by Joseph Schwantner and Reflections on the Nature of Water by Jacob Druckman have become two of the most influential works in contemporary marimba music. This thesis will focus on a historical perspective of the project, as well as theoretical aspects and performance issues related to these two compositions. The National Endowment for the Arts (NEA) issued a consortium commissioning grant through the Percussive Arts Society (PAS) in 1986 to three internationally renowned marimbists, William Moersch, Leigh Howard Stevens and Gordon Stout. Three Pulitzer Prize winners were brought together to compose three new works for the marimba. The resulting pieces were: Reflections on the Nature of Water by Jacob Druckman, Velocities by Joseph Schwantner, and Islands from Archipelago: Autumn Island by Roger Reynolds. A brief history of the classical concert marimba and the development of solo marimba literature is provided in the second chapter. The fourth and fifth chapters provide individual information about the pieces, including concise biographical information about the composers and an analysis of the two compositions.
