Devido ao aumento na produção de óleo pesado, a indústria do refino voltou-se para os processos de hidrocraqueamento (HCC) que fornecem combustíveis básicos e leves atendendo as exigências da sociedade moderna. O processo HCC é realizado, geralmente, sob temperaturas e pressões elevadas na presença do hidrogênio e de um catalisador de hidrocraqueamento. As cargas de petróleo brasileiras inevitavelmente contêm muitas impurezas, como os compostos orgânicos nitrogenados. Estes compostos de nitrogênio presentes nas cargas de hidrocraqueamento atuam como venenos temporários dos catalisadores, resultando numa diminuição de atividade destes catalisadores. Normalmente, os catalisadores de HCC compreendem de um suporte ácido mais um componente hidrogenante selecionado do Grupo VIB e do grupo VIII da Tabela periódica dos Elementos, na forma de óxido ou sulfeto. Zeólita Beta e SAPO-5 foram propostos para serem usados como suportes ácidos. A respeito do componente hidrogenante, a combinação de metais usados, expressada como óxidos, foi NiO-MoO3. Uma série de catalisadores NiMo suportados em Zeólita Beta e SAPO-5, de diferentes composições, foram preparados por impregnação seqüencial úmida dos materiais utilizando soluções aquosas precursoras de Ni(NO3)2.6H2O e (NH4)6 Mo7O24. 4H2O. Os suportes e catalisadores foram analisados pelas técnicas: Difração de raios-X (DRX), Espectrometria de Emissão Atômica de Plasma Acoplado Induzido (ICPAES), Adsorção Física de N2 pelo método BET, Redução com Temperatura Programada (RTP), Microscopia Eletrônica de Transmissão (MET), Espectroscopia no Infravermelho de piridina adsorvida (IV), Espectroscopia de Refletância Difusa (DRS) e Espectroscopia de Ressonância Magnética Nuclear (RMN). Os catalisadores NiMo sulfetados foram avaliados usando um reator tubular de fluxo contínuo, no hidrocraqueamento do cumeno na presença e ausência de piridina. Foi verificado que os catalisadores suportados em zeólita Beta promoveram maiores conversões que os suportados em SAPO-5, principalmente o que usou zeólita Beta (Si/Al=8,2) com 4%NiO e 15%MoO3. A presença da piridina foi prejudicial à performance de todos os catalisadores, inclusive para os padrões cedidos pelo CENPES.
Due to the increasing of the heavier crude oil feedstocks production, the oil refining industry has turned to hydrocracking (HCK) processes to provide the lighter basic fuels which modern society demands. The HCK process is generally carried out under high temperatures and pressures in the presence of the hydrogen and a HCK catalyst. The feedstocks of the Brazilian crudes inevitably contain many impurities, such as organic nitrogen compounds. These nitrogen compounds present in the feeds of hydrocracking process act as, temporary poisons to the catalysts, thereby decreasing the catalyst activity. Usually, hydrocracking catalysts comprise of an acidic support plus a hydrogenating component selected from the Group VIB metals and Group VIII metals of the Periodic Table of the Elements, in their oxide or sulfide form. Beta zeolite and SAPO-5 are proposed as acidic support materials for hydrocracking. Regarding the hydrogenation component the combination of the metals used in the form of oxides, was NiO-MoO3. A series of NiMo catalysts supported on Beta zeolite and SAPO-5, of different compositions, were prepared by sequential incipient wetness impregnation of the materials with aqueous solutions of Ni(NO3)2 . 6H2O and (NH4)6 Mo7O24.4H2O. The supports and catalysts were analyzed by several techniques such as: X-ray diffraction (XRD), plasma-emission spectrometry (ICP-AES), N2 physical adsorption by BET method, temperature programmed reduction (TPR), transmission electronic microscopy (TEM), infrared spectroscopy of adsorbed pyridine (IR), diffuse reflectance spectroscopy (DRS) and nuclear magnetic resonance (NMR) spectroscopy. The sulfide NiMo catalysts were evaluated using a continuous-flow tubular reactor by the cumene hydrocracking in the presence and absence of pyridine. It was verified that the NiMo catalysts based on Beta zeolite produced the highest cumene conversion than those based on SAPO-5, particularly the one with Beta zeolite (Si/Al=8,2) containing 4%NiO and 15%MoO3. The presence of nitrogen as pyridine was detrimental for the performance of all catalysts, including the standards one, supplied for the CENPES.

Steffel, Jennifer Elaine. "Storming the suburban fortress : understanding the NIMBY phenomenon". Thesis, McGill University, 1995. http://digitool.Library.McGill.CA:80/R/?func=dbin-jump-full&object_id=23704.
Texto completoThis thesis explores the processes by which discriminatory NIMBY sentiments are realized as legal development regulations in contemporary suburbs. The historic evolution of the suburbs and the psychological foundations behind their typical characteristics are presented as the sources of a suburban value structure which esteems NIMBY. Suburban governments are mandated to represent their constituents' values, but exclusionary development controls are a complex product of constituent demands, fiscal constraints, and constitutional limits.
This analysis reveals that legislative responsibility often bows to political weakness. NIMBY groups use political pressure to manipulate municipal governments into using their vast discretionary powers over development as a weapon for exclusion. In response to either political or fiscal motivations, legislators pressure planners to validate discriminatory legislative agendas with their plans, thus undermining their abilities to guide growth effectively. Although the process of development regulation is well-grounded in historic and legal precedents, when legislation is used for discriminatory ends, citizens' civil and property rights are jeopardized. This thesis explains how regulations such as zoning ordinances can be used for exclusion when municipal government disregards its mandate to be the guardian of the general welfare.
Increased awareness of both the motivations and the manifestations of the NIMBY phenomenon may enable individuals as well as lawmakers to create a more equitable suburbia.

Texto completoNowadays, the transformation of lignocellulosic biomass is deeply investigated in order to provide biofuels and chemicals. Lignin, a by-product of pulp and bio-ethanol industry, is an available resource which could be used for the production of aromatic and phenolic compounds. However, this macromolecule mainly made of propylphenolic units linked by ether functions needs to be depolymerized. This work focuses on the study of liquefaction mechanisms by catalytic hydroconversion of wheat straw lignin extracted by a soda pulping. In the first part of this study, an in-depth characterization of this lignin was carried out using techniques. A structure of our lignin was proposed as a result. Then, a procedure was developed to perform the catalytic hydroconversion and recover the products. Catalytic experiments were carried out in a semi-batch reactor at 350°C, using H2 (8 MPa), a hydrogen donor solvent (tetralin) and a sulfide NiMoP/Al2O3 catalyst. The recovered products were separated into a liquid phase, gases, a lignin residue and THF insoluble solids. A conversion of 81 wt% of lignin into non-solid products was reached after 28h of reaction with an excellent mass balance. The characterization of the different fractions was carried out using techniques. Thanks to this protocol, we were able to point out the role of the H-donor solvent for preventing solid formation as well as the role of the catalyst for hydrodeoxygenation and hydrogenation of the depolymerized products. Finally, the catalytic hydroconversion of the lignin was carried out with the different residence times, which helps understanding the transformations occurring during the conversion. At the beginning of the reaction, we observed decarboxylation, hydrogenolysis of aliphatic OH and cleavage of ether linkages between the phenolic units of the lignin. Then, we observed elimination of methoxy groups, mainly by demethylation followed by dehydroxylation. Finally, the main products obtained during the reaction were phenolic and deoxygenated compounds such as aromatics, naphthenes and alkanes

Texto completoPå senare tid har antalet barn och ungdomar som tvingats på flykt till Sverige åtskilda från sina föräldrar succesivt ökat. Dessa går under benämningen ensamkommande barn. En kunskapslucka inom tidigare forskning angående åtagandet av ensamkommande barn är den betydelse grannskapet till HVB-hem, som många av dessa barn placeras i, kan spela. Syftet med föreliggande studie har därmed varit att undersöka grannskapskontakter med boende för ensamkommande barn med hjälp av en fallstudie av ett HVB-hem i Gislaveds kommun, HVB-hemmet Furugården i Smålandsstenar, och att från dessa utgångspunkter belysa den roll grannskap kan spela för integrationssträvande. Studien har utgått från de teoretiska begreppen: NIMBY och Kontakthypotesen vilka inom studien har ämnat förklara grannskapets inverkan på ensamkommande barns integration För att uppnå studiens syfte har totalt 23 semistrukturerade intervjuer av kvalitativ karaktär genomförts med HVB-hemsansvariga och med HVB-hemmets grannskap, det vill säga grannar.

Texto completoWith the progressive decrease of oil resources, the production of biomass fuel is a fast growing field. This could limit the concentration of carbon dioxide in the atmosphere and thus the global warming. The production of this kind of fuel requires the use of catalysts such as nickel or cobalt promoted molybdenum sulfide. These materials are also crucial during the refining of oil, an essential step to limit atmospheric pollution during the classic fuel combustion. New methods to synthesize and structure NiMoS catalysts have been developed in this work. Two solvants have been studied: formamide and water. The addition of an amphiphilic water-soluble polymer (PEO113-b-PLLA32) in water and of ionic liquids (BMIMNTf2 and BMIMBF4) in formamide led to the structuring of the materials with specific surface areas up to 55 m2g-1. This is a high value for this kind of material, especially since the synthesis is carried out under soft conditions. The first catalytic tests dealt with decanoïc acid hydrodesoxygenation and highlighted a promising activity for these materials

Desde a regulamenta??o como profiss?o no Brasil, a forma??o em Psicologia se constr?i em torno da ideia de um curso generalista. A mudan?a de Curr?culo M?nimo para Diretrizes Curriculares Nacionais (DCN) abrangeu v?rios debates, a forma??o generalista permaneceu como um consenso, mas com novos sentidos. O objetivo deste trabalho foi investigar as concep??es e estrat?gias atuais de forma??o generalista nos cursos de Psicologia da cidade de Natal-RN. Foram analisados os Projetos Pedag?gicos de Curso (PPC), matrizes curriculares e entrevistas com os coordenadores dos cursos e docentes que participaram da cria??o do curr?culo. A pesquisa contou com quatro cursos participantes, sendo que tr?s forneceram seus PPCs e os quatro participaram por meio de entrevistas. Os dados foram agrupados em categorias criadas a posteriori. Foi constatado um discurso uniforme em torno da defesa de uma forma??o generalista. Os curr?culos s?o conteudistas, mostram uma predomin?ncia da ?rea cl?nica e pouca ?nfase no estudo de fundamentos filos?ficos e hist?ricos, relacionam forma??o generalista a um curr?culo diversificado nas teorias e campos de atua??o profissional, buscando uma integra??o de disciplinas por meio de atividades e experi?ncias pr?ticas. Relacionam pesquisa e integra??o curricular, mas os incentivos na maioria dos cursos s?o parcos. O discurso de compet?ncias est? presente, ainda que se tenha pouca clareza sobre sua concretiza??o. Os cursos comparam ?nfases curriculares ? ?reas da Psicologia, o que torna o termo controverso, revelando uma compreens?o dicot?mica entre forma??o generalista e especialista. Assim, a predomin?ncia de um conteudismo voltado para a pr?tica profissional tem separado teoria e pr?tica e obscurecido uma concep??o cr?tica de forma??o como forma??o humana, filos?fica, hist?rica e cient?fica.
Since its regulation as a profession in Brazil, training in Psychology has been built over the idea of a generalist course. The change from Minimum Curriculum to National Curricular Guidelines (NCG) included a series of discussions and generalist training remained a consensus, but with new meanings. The objective of this study was to investigate the concepts and current strategies on generalist training in psychology courses in the city of Natal-RN. Therefore, we analyzed the Pedagogical Projects of the Courses (PPCs) and conducted interviews with coordinators and professors who participated in the creation of the curriculum. The research included four participating courses, of which three provided their PPCs and the four courses participated in interviews. Data was grouped into categories created a posteriori. We noticed a uniform discourse around the defense of a generalist training. The curricula are conteudists, show predominance of the clinical area and have little emphasis on the study of philosophical and historical foundations, generalist training is related to a diverse curriculum in theories and professional fields, seeking for integration of disciplines through activities and varied practical experience. The courses connect research and curriculum integration, but the incentives in most courses are meager. The competencies discourse is present, although it has not clarity about how to implement it. The courses compare curricular emphases with areas of psychology, which makes the term controversial, revealing a dichotomous understanding between generalist and specialist training. Thus, the predominance of a conteudism related to a professional training have generated a separation between theory and practice and obscures the critical conception of generalist training as a human, philosophical, historical and scientific formation.

This study aimed to evaluate the quality of 'Sweet Celebration' and 'Sweet Globe' grapes, subjected to minimally processing, as well as the effectiveness of three rinsing solutions (water, sodium metabisulfite and chlorine) and pedicel cut intensity (with and without pedicel), in the conservation of these fruits during 12 days refrigerated storage to temperature at 8 ? C . The experiments were performed at Embrapa Agroind?stria de alimentos. For both experiments were applied rinse solutions, with water, sodium metabisulfite (20 mg. L-1) and chlorine (8 mg. L-1), that characterized the treatments, during the rinse step of minimally processing grapes, it being used two pedicel cut intensities:full cut and maintenance of a little fragment about 0,5 cm. Quality analyzes were performed at 0, 3, 6, 9, and 12 days of storage, and it was determined fresh weight loss cumulative , fruit firmness, color analysis, acidity, pH, total soluble solids, SST/ATT rate , sugars (sucrose , fructose and glucose) and enzymatic activity of pectinametilesterase for both cultivars. For Sweet Celebration grapes were also carried out the percentage fruit loss (9th and 12th day of storage) and anthocyanins. In 'Sweet Globe' grapes were realized total carotenoids, chlorophylls (a, b and total) and microbiological analyses. To the cultivate Sweet Celebration was possible identify berries out of commercial standard in the 9? day of storage. In the fresh weight loss cumulative, berries without pedicel had higher loss in the rinse with water from the 6th day of storage. For berries with pedicel the rinse with chlorine had the lowest fresh weight loss cumulative up 9th day of storage. For the firmness , berries without pedicel (4.44 N) had lower firmness compared to berries with pedicel (5.04 N), there wasn't significant difference between the rinsing solutions (p> 0.05). To cultivate Sweet Globe, berries with pedicel and rinsed with water had higher fresh weight loss cumulative from the 9th day of storage. In the berries without pedicel the rinse with water led to lower fresh weight loss cumulative from the 6th day of storage. There was no difference between the isolated factors rinse solutions and pedicel cut intensit to the firmness analysis. All rinse solutions were efficient in the microbiological analysis, so the minimally processed Sweet Globe grapes were in the standard established by law for human consumption
O presente trabalho objetivou avaliar a qualidade de uvas ?Sweet Celebration? e ?Sweet Globe?, submetidas ao processamento m?nimo, assim como a efetividade de tr?s solu??es enxaguantes (?gua, metabissulfito de s?dio e cloro) e da intensidade de corte do pedicelo (com e sem pedicelo), na conserva??o desses frutos, durante 12 dias de armazenamento refrigerado a 8?C. Os experimentos foram realizados na Embrapa agroind?stria de alimentos. Para ambos experimentos, foram aplicadas solu??es de enx?gue, com ?gua, metabissulfito de s?dio (20 mg. L-1) e cloro (8 mg. L-1), que caracterizaram os tratamentos, durante a etapa de enx?gue do processamento m?nimo das uvas, sendo adotadas duas intensidades de corte do pedicelo: retirada total do mesmo e manuten??o de um pequeno fragmento com aproximadamente 0,5 cm. Foram realizadas an?lises de qualidade nos 0, 3, 6, 9, e 12 dias de armazenamento, sendo determinadas a perda acumulada de massa fresca, firmeza dos frutos, an?lise de cor, acidez, pH, s?lidos sol?veis totais, rela??o SST/ATT, a??cares (sacarose, frutose e glicose) e atividade enzim?tica da pectinametilesterase para as duas cultivares. Para as uvas Sweet Celebration, foram tamb?m realizadas a porcentagem de perda de frutos (9? e 12? dia de armazenamento) e antocianinas totais. Para as uvas ?Sweet Globe?, foram realizadas as an?lises de caroten?ides totais, clorofilas (a, b e total) e an?lise microbiol?gica. Para a cultivar Sweet Celebration, foi poss?vel detectar bagas fora de padr?o comercial no 9?dia de armazenamento. Na perda acumulada de massa fresca, bagas sem pedicelo apresentaram maior perda no enx?gue com ?gua a partir do 6? dia de armazenamento. Para bagas com pedicelo o enx?gue com cloro apresentou a menor perda acumulada de massa fresca at? o 9? dia de armazenamento. Para a firmeza das bagas, bagas sem pedicelo (4,44 N) apresentaram menor firmeza, quando comparadas ?s bagas com pedicelo (5,04 N), n?o havendo diferen?a significativa entre as solu??es de enx?gue (p> 0,05).

Texto completoO objetivo central deste trabalho ? estudar o munic?pio de Charqueadas, considerando o desenvolvimento do munic?pio vizinho, S?o Jer?nimo, como par?metro de compara??o. Charqueadas apresentou um crescimento populacional e econ?mico significativamente maior que o Estado como um todo. Al?m disso, em 1982, Charqueadas se emancipou do munic?pio de S?o Jer?nimo e este ?ltimo tem apresentado crescimento mais lento, acompanhado de uma diminui??o de sua popula??o. O diferencial de crescimento econ?mico entre os dois munic?pios foi analisado ? luz das teorias de desenvolvimento regional, fornecendo uma maior sustenta??o te?rica para a investiga??o. Al?m disso, foram feitas entrevistas com alguns agentes p?blicos e do setor privado dos dois munic?pios na tentativa de melhor mensurar as causas dos diferenciais de crescimento. Charqueadas, o munic?pio mais jovem, beneficiou-se no processo de emancipa??o e, sobretudo, com a presen?a da estrutura industrial de uma grande empresa que impulsionou a forma??o do p?lo metal-mec?nico municipal. S?o Jer?nimo, o munic?pio mais velho, n?o conseguiu incluir-se no mesmo processo de industrializa??o, persistindo num padr?o de atividade econ?mica centralizado na agroind?stria, com?rcio e servi?os.

Mo, NiMo or NiMoP HDS catalysts were supported on Al2O3, Al2O3-TiO2 or TiO2. These supports were synthesized via sol-gel and in the case o TiO2 it was used a commercial sample. The active phases were introduced by impregnation. Supports and catalysts in the oxide form were characterized by X-ray diffraction (XRD), diffuse reflectance UV-Vis spectroscopy (DRSUV-Vis), thermogravimetric analyses (TG), temperature-programmed reduction with H2 (TPR-H2), N2 adsorption/desorption, energy dispersive X-ray spectroscopy (EDS), X-ray fluorescence (XRF), temperature-programmed desorption of NH3 (TPD-NH3), high resolution transmission electron microscopy (HRTEM) and evaluated at 300°C in the HDS of thiophene, used as a model molecule. Alumina presented a high specific surface area and meso/macroprous characteristics, allowing a high dispersion of the active phases, as was evidenced by XRD and DRSUV-VIS data. A HRTEM image of a NiMo/Al2O3 catalyst showed the presence of crystalline MoS2 whose activity was substantially promoted by the presence of Ni. The NiMo catalysts were active in the HDS of thiophene, however, the activity was enhanced significantly by the incorporation of P. This result corroborates the positive influence of P in the preparation of HDS catalysts. It was suggested that P must participate as promoter in the formation of the NiMoS phase during the sulfidation process of the Ni and Mo oxides. The supported NiMoP catalysts prepared in this work were more active than a commercial NiMoP/ Al2O3 catalyst, with this result validating the preparation procedures used here. The titania addition in the alumina framework led to NiMo catalysts possessing lower activity. That behavior was attributed to the formation of Ni and Mo sulfides without interaction diminishing the generation NiMoS phase, which is highly active in the HDS of sulfured organic compounds.
Catalisadores para hidrodessulfurização (HDS) contendo Mo, NiMo ou NiMo e o aditivo fósforo (P), foram suportados sobre Al2O3, Al2O3-TiO2 ou TiO2. A alumina e a alumina-titânia foram sintetizadas via sol-gel e, no caso da titânia pura, utilizada uma amostra comercial. A introdução dos sais precursores da fase ativa foi realizada via impregnação. Suportes e catalisadores na forma de óxidos foram caracterizados através de difração de raios X (DRX), espectroscopia por refletância difusa no ultravioleta visível (DRSUV-VIS), termogravimetria (TG), redução com hidrogênio à temperatura programada (RTP-H2), adsorção/dessorção de N2, espectroscopia de energia dispersiva de raios X (EDX), fluorescência de raios X (FRX), dessorção de amônia a temperatura programada (TPD-NH3), microscopia eletrônica de transmissão de alta resolução (HRTEM) e avaliados a 300⁰C na HDS do tiofeno. A alumina apresentou uma alta área superficial específica e características meso/macroporosa, possibilitando alta dispersão das fases ativas, conforme evidenciado por DRX e dados de DRSUV-VIS. A imagem de HRTEM do catalisador NiMo/Al2O3 mostrou a presença de MoS2 cuja atividade foi promovida substancialmente pela presença de Ni. Os catalisadores NiMo sobre os suportes utilizados foram ativos no HDS do tiofeno, entretanto, essa atividade foi melhorada pela incorporação de P. Esse resultado ratifica a influência positiva da utilização desse aditivo na preparação de catalisadores de HDS. O fósforo deve atuar como um promotor na formação de espécies NiMoS durante o processo de sulfetação dos óxidos de Mo e Ni. Os catalisadores NiMoP preparados neste trabalho apresentaram atividade específica superior à de um catalisador NiMoP/Al2O3 comercial, o que valida os procedimentos de preparação utilizados no trabalho. A adição de titânia na alumina durante a síntese sol-gel conduziu a catalisadores com menor atividade. Esse resultado foi atribuído à formação de sulfetos de Ni e Mo não interativos, com a consequente diminuição da formação da fase NiMoS de alta atividade no HDS de compostos organo-sulfurados.

Texto completoIn hydrodesulfurization of fossil fuels, the sulfur levels are reduced by sulfur extraction from hydrocarbons by using supported catalysts (MoS2), doped (Co, Ni). Ultra-deep hydrodesulfurization will be achieved by improving new catalysts. Nanoparticles are a promising candidate with their high S/V ratio and permit to use the precise amount of metallic sulphide. The aim of this thesis is the synthesis of core@shell nanometric catalyst with improved activities. Core composed of Fe3O4 or nanodiamonds will be surrounded by a shell formed of MoS2, NiMoS, CoMoS or NiCoMoS, supported on TiO2, γ-Al2O3. Model reaction (thiophene) has allowed to compare conversion rates between each catalyst. Additionally, characterizations have provided a better understanding of the HDS catalyst structure and performances. Some factors have been investigated such as the size of the core, theinteractions between the core and the shell, the type of synthesis, the support chosen, the synergetic effect with doping ions and also the activation of the catalyst at low temperature

Texto completoThe thesis objective is to identify the support acidity effects of sulfide catalysts in hydrodenitrogenation (HDN) reactions in order to improve the HDN catalysts.Kinetic data obtained from quinoline and indole HDN, over NiMo(P)/Al2O3 and NiMo(P)/ASA catalysts were analyzed by a Langmuir-Hinshelwood kinetic model, including liquid-vapor mass transfer, in order to estimate kinetic and adsorption parameters. Kinetic modeling results indicated that the NiMo(P)/ASA catalyst favored the hydrogenation of 1,2,3,4-tetrahydroquinoline into decahydroquinoline, which is the rate limiting step of quinoline HDN. However, the promoting effect of the NiMo(P)/ASA in hydrogenation steps of indole HDN was not evidenced. In quinoline and indole HDN, the NiMo(P)/ASA showed a strong promoting effect in N-removal reactions. Nitrogen compounds adsorb more strongly over NiMo(P)/ASA. Characterization by Infra-Red spectroscopy of CO suggested that these results might be related to the modification of the electronic properties of promoted NiMoS phase due to higher acidity of ASA.The HDN of quinoline-indole mixture showed a strong inhibiting effect of quinoline on indole HDN whereas the inhibiting effect of indole on quinoline HDN was negligible over NiMo(P)/Al2O3 and more important over NiMo(P)/ASA. The HDN of a mixture of Straight Run and Coker Gas Oil allowed an access to the HDN mechanism and comparison of reactivity towards HDN of different compounds. The HDN of neutral compounds was inhibited by the stronger adsorption of basic compounds. Carbazole-type and quinoline-type compounds were refractory. The NiMo(P)/ASA likely favored more cracking reactions and as well showed a faster deactivation rate than the Al2O3 counter catalyst

This work has as objective reflect on the emergence and implementation of the Minimum Curriculum (CM) in the State Education Network, specifically in the Biology discipline, in 2012, presented by the State Department of Education of the State of Rio de Janeiro (SEEDUC). From the socio-historical studies of the curriculum, it is sought to understand the elements that supported the emergence and implantation of the CM and how this proposal refines the external evaluations in the state, ENEM (National High School Exam) and SAERJ (Evaluation of Education in the State of Rio de Janeiro). This work constitutes a qualitative research, based on theoretical and methodological, based on the curricular studies dialoguing with the empirical sources constituted by the documents related to the emergence and implantation of the curriculum (information of the SEEDUC website, Resolution 4.866 of February 14, 2013, Minimum Curriculum of Biology, Earnings by Results SEEDUC) and by published articles on the subject. The initial objective is that through the interbreeding of these written sources one can construct a narrative about the minimal curriculum of the biology curricular component. From the analysis of the official documents regarding the CM, with regard to the concept of skills and competences, it is possible to note its proximity to the external evaluations, since the curriculum and other strategies created by SEEDUC aim to corroborate with the increase of the index Of State education in external evaluations such as IDEB (Indicator and Development of Basic Education). The CM of Biology presents skills and competences, which SEEDUC claims to be organized progressively in the official document - from the simplest or most concrete, towards a more complex or abstract one. However, analyzing this document, the two-month course distributed in the CM of biology, it is possible to sustain that this progression of contents does not always happen, it presents in a sparse and irregular form. In this sense, it was possible to perceive when analyzing the document of the CM of Biology that the teaching continues to be presented in a fragmented way; Hindering the student to associate what he / she learns in school with his daily life. After analyzing the CM of Biology, the idea that the meanings of the concepts of competences and abilities, although approaching the cognitive-constructivist side of Perrenoud, is also moved towards Tyler's compartamentalism, when he centralizes his questions in External evaluations, the accountability curriculum and performativity
Este trabalho tem como objetivo refletir sobre o surgimento e implanta??o do Curr?culo M?nimo (CM) na rede Estadual de Educa??o, especificamente na disciplina Biologia, em 2012, apresentado pela Secretaria de Estado de Educa??o do Estado do Rio de Janeiro (SEEDUC). A partir dos estudos s?cio-hist?ricos do curr?culo, busca-se compreender os elementos que sustentaram o surgimento e implanta??o do CM e como esta proposta se afina as avalia??es externas presentes no estado, ENEM (Exame Nacional do Ensino M?dio) e SAERJ (Sistema de Avalia??o da Educa??o do Estado do Rio de Janeiro). Este trabalho constitui uma pesquisa qualitativa, a base te?rico-metodol?gica, apoiou-se nos estudos curriculares dialogando com as fontes emp?ricas constitu?das pelos documentos relativos ao surgimento e implanta??o do curr?culo (informa??es do site da SEEDUC, Resolu??o 4.866 de 14 de fevereiro de 2013, Curr?culo M?nimo de Biologia, Bonifica??o por Resultados SEEDUC) e por artigos publicados a respeito do tema. O objetivo inicial ? que se possa atrav?s do intercruzamento destas fontes escritas construir uma narrativa a respeito do curr?culo m?nimo da componente curricular biologia. A partir da an?lise dos documentos oficiais a respeito do CM, no que se refere ao conceito de habilidades e compet?ncias, nota-se sua proximidade com as avalia??es externas, visto que o curr?culo e outras estrat?gias criadas pela SEEDUC almejam corroborar com a eleva??o do ?ndice da educa??o do Estado em avalia??es externas como o IDEB (Indicador e Desenvolvimento da Educa??o B?sica). O CM de Biologia apresenta habilidades e compet?ncias, as quais a SEEDUC argumenta estar organizada de forma progressiva no documento oficial ? da mais simples ou concreta, em dire??o a uma mais complexa ou abstrata. Todavia, analisando este documento, os bimestres letivos distribu?dos no CM de biologia, ? poss?vel sustentar que esta progress?o de conte?dos nem sempre acontece, apresenta-se de forma esparsa e irregular. Neste sentido, foi poss?vel perceber ao analisar o documento do CM de Biologia que o ensino continua a ser apresentado de forma fragmentada; obstaculizando o estudante associar o que aprende na escola com seu cotidiano. Ap?s an?lise do CM de Biologia, sustenta-se a ideia de que os sentidos dos conceitos de compet?ncias e habilidades embora se aproximem da vertente cognitivoconstrutivista, de Perrenoud, tamb?m se movimenta em dire??o ao compartamentalismo de Tyler, quando centraliza suas quest?es em avalia??es externas, no curr?culo do accountability e na performatividade.

This paper, bearing the title Fundamental social rights and existential minimum: An emancipation agenda for the development of citizenship, seeks to locate the function of the fundamental social rights existential minimum in fostering citizenship within the institutional framework of pluralistic democracy and, as a result, in conceiving the human being as an autonomous decision-making center, and also to establish criteria guiding the outline of its normative content. For this, John Rawls?s theory of justice as fairness in its original version is investigated, especially in its political outline, as well as the criticism and counter-arguments brought by Amartya Sen?s idea of justice and specifically the capabilities approach by Amartya Sen, Martha Nussbaum and Elizabeth Anderson, thus setting up a theoretical common ground in order to understand the existential minimum as a fundamental social right. The origins and evolution of the concept of citizenship are reviewed, establishing its characteristic elements and deducing its meaning in today?s political scenario from the different currents concerning its coming into being. Arguments are analyzed about the concepts of citizenship offered by the republican, communitarian, and liberal currents, pointing their deficiencies and biases and showing that the social dimension of citizenship shares the same space and the same importance status of both remaining dimensions (civil and political citizenship), stressing that the notion of citizenship as a whole is jeopardized in the case any one of them is missing. A point is made that a basic set of social contributions is an essential part of democratic citizenship. The function of the existential minimum is defined as the fostering and (re)building of citizenship. The close link between the existential minimum and the exercise of democracy and the full attainment of citizenship is highlighted. Finally, it is proposed that the existential minimum?s normative content must include a fairness index of primary social goods and/or the material (factual) conditions that allow people access to these interests, while taking into account the society?s peculiarities.
O presente trabalho, que tem por t?tulo Direitos fundamentais sociais e m?nimo existencial: uma pauta emancipat?ria para o desenvolvimento da cidadania, tem como objetivos, de um a lado, situar a fun??o do m?nimo existencial dos direitos fundamentais sociais na promo??o da cidadania no contexto institucional de uma democracia pluralista e, como decorr?ncia, na edifica??o da pessoa humana enquanto centro aut?nomo de decis?o; de outro, estabelecer par?metros para orientar o delineamento do seu conte?do normativo. Para tanto, investiga a teoria da justi?a como equidade de John Rawls, em sua vers?o original e, sobretudo, na concep??o pol?tica, bem como as contraposi??es e cr?ticas trazidas pela ideia de justi?a de Amartya Sen e, especialmente pela abordagem das capacidades de Amartya Sen, Martha Nussbaum e, tamb?m, Elizabeth Anderson, de modo a lograr um adequado embasamento te?rico para a compreens?o do m?nimo existencial enquanto direito fundamental social. Examina o surgimento e a evolu??o do conceito de cidadania, delimitando seus elementos caracter?sticos e haurindo o seu significado no contexto pol?tico atual a partir das diferentes correntes sobre o seu processo de forma??o. Analisa os argumentos das concep??es de cidadania das correntes republicana, comunit?ria e liberal, mostrando as insufici?ncias e distor??es e demonstrando que a dimens?o social da cidadania compartilha o mesmo espa?o e est? no mesmo patamar de import?ncia e valor que as outras duas dimens?es, a cidadania civil e a cidadania pol?tica, sublinhando que, sem qualquer delas, fica comprometida a no??o de cidadania como um todo. Aponta que um conjunto b?sico de presta??es sociais ? parte essencial da cidadania democr?tica. Desvenda que a fun??o do m?nimo existencial ? a promo??o e a (re)constru??o da cidadania. Ressalta a estreita vincula??o do m?nimo existencial com o exerc?cio da democracia e a plena realiza??o da cidadania. E prop?e que o conte?do normativo do m?nimo existencial deve abranger um ?ndice equitativo de bens prim?rios sociais e/ou as condi??es materiais (f?ticas) que possibilitem ?s pessoas o acesso a esses bens, considerando as peculiaridades da sociedade.

Texto completoThis study is a part of a wider multiple case study conducted in Jönköping county. It is examining a residential HVB-home for unaccompanied refugee children in Jönköping city. The purpose of this qualitative case study is to examine the neighborhood’s potential role in integration of unaccompanied refugee children. Semi-structured interviews were carried out with neighbors (n=11) and with representatives for the HVB-home (n=3). Furthermore, the study examines what information strategies have been used in the establishment process of HVB-home, along with what this has meant for the reception of the home in the neighborhood. The study finds that the neighborhood perceives the examined HVB-home as anonymous and there is a noticeable lack of information and knowledge about the home amongst the neighbors. The neighbors requests more information about the HVB-home and generally have indifferent or positive attitudes towards the location and existence of the HVB-home and the unaccompanied refugee children. The degree of acceptance of the home could be explained by the information strategy the HVB-home initially chose for the establishment of the home or the lack of knowledge about the home amongst the neighbors, although further explanations could be given. The lack of contact between the HVB-home and the neighborhood could partially be explained by the HVB-home’s choice to keep a low profile in the neighborhood. In addition, the study can distinguish an unexplored potential for the neighborhood to possible play an important role in the integration of the unaccompanied refugee children.

Esta disserta??o insere-se no ?mbito da Perspectiva Textual-Interativa (JUBRAN; KOCH, 2006), que constitui uma vertente da Lingu?stica Textual. A pesquisa tem como prop?sito investigar a estrutura??o dos Segmentos T?picos M?nimos (SegTs m?nimos) em aulas para o ensino m?dio, bem como descrever esse processo. A unidade de an?lise tomada para a consecu??o desses objetivos ? o t?pico discursivo, uma vez que essa categoria permite operar no recorte de segmentos t?picos como tamb?m dos segmentos t?picos m?nimos. Do ponto de vista metodol?gico, o trabalho adotou o m?todo emp?rico-indutivo de an?lise, a partir de uma abordagem qualitativa. Partindo da proposta de investigar como ocorre o processo de estrutura??o interna de SegTs m?nimos (PENHAVEL, 2010) em aulas expositivas (SILVA, 2008), coletamos dados correspondentes a aulas de Biologia, de Geografia, de Hist?ria e de Portugu?s, em uma escola de Ensino M?dio da rede p?blica do estado de Pernambuco. Nessa dire??o, para realizar uma an?lise mais detalhada dos segmentos t?picos m?nimos, selecionamos uma das aulas para an?lise, por considerarmos que ? representativa dentro do conjunto das aulas expositivas. Finalmente, verificamos nas an?lises que o processo de estrutura??o dos SegTs m?nimos, particularmente da aula expositiva, tem como princ?pio geral o encadeamento sequencial de quatro unidades t?picas: Esquematiza??o inicial, Problema(quest?o), Explica??o e Ratifica??o-avalia??o. Al?m dessa, h? outras formas de estrutura??o que se realizam com tr?s, duas ou uma unidade t?pica, cujas bases permanecem no princ?pio geral de estrutura??o dos SegTs m?nimos. Assim, identificamos entre as formas mais recorrentes, SegTs organizados com base no encadeamento sequencial Quest?o-Explica??o-Avalia??o, Esquematiza??o inicial-Explica??o-Avalia??o; ou apenas Esquematiza??o inicial-Explica??o, Explica??o-Avalia??o. H? ainda SegTs estruturados t?o-somente com a unidade de Explica??o que ? a ?nica unidade t?pica de estrutura??o que ocorre em todos os SegTs.
This paper is part of the framework of the Textual-Interactive Grammar or Textual-Interactive Perspective (Jubran, KOCH, 2006), which is a branch of Textual Linguistic. The research aims to investigate the structure of the Minimum Topic segments in classes for high school, and to describe this process. The unit of analysis taken to accomplish these objectives is the discursive topic, because that category will operate in cropping topic segments as well as Minimum Topic segments. From a methodological point of view, the study adopted the empirical-inductive method of analysis from a qualitative approach. From the proposal to investigate how is the internal structuring of Minimum Topic SegTs (PENHAVEL, 2010) in expositive classes (SILVA, 2008), we collected corresponding biology, Geography, History and Portuguese classes, in a public school from Pernambuco. In this direction, to carry out a more detailed analysis of the topic segments, we selected one of the classes for analysis, because we believe that is representative in a set of classes. Finally, we noted in the analysis that the process of internal structuring of minimum SegTs, particularly the expositive classes, has as a general principle of structuring the sequential chaining four topical units: Outlining initial, Problem (question), Explanation and Ratification-assessment. In addition to this, there are other ways of structuring carried out with three, two or one topical unit but they based on the general principle of structuring of minimum SegTs. Thus, we identified among the most recurrent forms, SegTs are organized with the sequential chaining Question, Explanation, Ratification-assessment; Outlining initial, Explanation, Ratification-assessment; or just Outlining initial, Explanation, Ratification-assessment; Explanation, Ratification-assessment. There are still SegTs structured only with the Explanation unit. Furthermore, it is the only topic unit that occurs in all SegTs.

Resumo: Sólidos monometálicos e bimetálicos de níquel e molibdênio suportado em alumina foram impregnados com 3% de teor metálico variando a ordem de impregnação até umidade incipiente, os quais podem ter efeitos significativos sobre o seu desempenho. As amostras foram calcinadas e caracterizadas, e utilizadas na desoxigenação catalítica do etilenoglicol. Esses materiais apresentaram áreas superficiais entre 177 e 160 m²g-¹. Os difratogramas de raios X de todos os sólidos obtidos exibiram a fase 'gama'-alumina e mediante o detector de energia dispersiva de raios X se confirmou a presença dos metais nos sólidos. Os testes catalíticos foram realizados em um reator de leito fixo, nas temperaturas de 533, 553, 573, 593 e 613 K e pressões de vapor do etilenoglicol de 13148 e 8662 Pa; a massa dos sólidos utilizada foi 35mg. Os compostos identificados foram a água, hidrogênio, metano, etano, éter etílico, acetaldeído e etanol. Foi realizado o balanço de mols do sistema e os valores dos graus de avanço de cada reação. Os cálculos dos efeitos difusivos demonstraram que as transferências de massa interna e externa e a transferência de energia externa não foram limitantes nas reações. Seis reações principais foram observadas e mediante os graus de avanço permitiu a avaliação de cada reação na formação dos determinados produtos de reação. Baseados na literatura se utilizaram expressões da taxa de reação para as reações propostas neste estudo. A seletividade aos produtos e conversão na desoxigenação do etilenoglicol apresentou mudanças baseadas na forma da ordem de impregnação dos sólidos. Igualmente foram realizados os cálculos das energias de ativação, fatores préexponenciais e as constantes da taxa
Abstract: Monometallic and bimetallic catalysts of nickel and molybdenum supported on alumina were prepared by incipient wetness with 3% metal content by varying the order of impregnation. The samples were calcined, characterized and used in the catalytic deoxygenation of ethylene glycol. The surface areas of the solids varied between 177 and 160 m²g-¹. The X-ray diffraction patterns of all solids had only 'gamma'-alumina phase. Analysis by X-ray dispersive energy confirmed the presence of both Ni and Mo in the solids. The catalytic tests were carried out in a fixed bed reactor and the reaction temperatures varied between 533 and 613 K while the vapor pressures of ethylene glycol were 8662 and 13148 Pa. The mass of the catalyst was kept constant at ca. 35mg. The identified compounds were water, hydrogen, methane, ethane, diethyl ether, acetaldehyde and ethanol. A mass balance for the reaction system was carried out and the extent of reaction was calculated for each reaction. The effect of diffusion was calculated and the results suggest that no internal or external mass transfer and external energy transfer were limiting in the reaction conditions used in this work. Rate expressions from the literature were used in this work. The results of conversion and selectivity to products in the deoxygenation of ethylene glycol reaction suggest that changes in the order of impregnation of the solid are important

Texto completoO crescimento da despesa p?blica ? um fato inevit?vel. Para garantir a sustenta??o da estrutura estatal e a presta??o de servi?os p?blicos, os governantes se valem, essencialmente, da tributa??o. Ocorre que, por toda a parte, verifica-se o agravamento demasiado da carga tribut?ria. Especialmente nos pa?ses perif?ricos, ? bastante preocupante a absor??o de percentuais expressivos da renda individual ou empresarial pela via da tributa??o, dado o risco de comprometimento do pr?prio desenvolvimento s?cio-econ?mico. Essa tend?ncia tem suscitado, mais na doutrina do que na jurisprud?ncia, o debate sobre a necessidade do estabelecimento de limites mais expl?citos ao poder de tributar. Esses limites, inerentes ao Estado Democr?tico de Direito, j? constam em diversas regras e princ?pios constitucionais. Destacam-se, no presente estudo, os princ?pios da igualdade, da dignidade da pessoa humana, da veda??o de confisco e da capacidade contributiva. Em que pese o status constitucional das limita??es, sua for?a vinculante, com rela??o aos Poderes de Estado, n?o tem se mostrado eficaz. Come?a a ficar evidente que n?o basta priorizar a arrecada??o, a qualquer pre?o. Na rela??o jur?dico-tribut?ria, ambos os sujeitos Estado e cidad?o merecem considera??o. Imp?e-se, de forma premente, o planejamento da a??o governamental, em termos t?cnicos, al?m de um controle mais efetivo das pol?ticas e dos gastos p?blicos. Com isso, poderiam ser atenuados os n?veis de incid?ncia tribut?ria sobre os membros da comunidade, com melhores resultados. Todos os cidad?os devem ter assegurado pelo Estado um m?nimo existencial, que lhes permita viver em condi??es de dignidade e de se desenvolver, por meio da inclus?o social em condi??es igualit?rias. Cada vez mais ganha relevo a figura do cidad?o-contribuinte, titular de direitos fundamentais que n?o se esgotam no cat?logo do artigo 5? da Constitui??o Federal. Nesse sentido, v?rios s?o os Estados a editar Estatutos que lhe confiram tutela espec?fica. A mudan?a de foco tende ? promo??o da justi?a fiscal, obtida pelo ajuste do tributo ao potencial de riqueza de cada um, para culminar na justi?a social, onde a nota ? o car?ter redistributivo da renda, por meio do emprego adequado dos recursos advindos da tributa??o.
