Assim, vários estudos utilizando matérias adsorventes estão sendo conduzidos como forma de reduzir os efeitos poluidores desses metais. E importante conhecer o processo de adsorção de metais pesados por minerais de argila, uma vez que estes são capazes de imobilizar referidos metais. No presente trabalho avaliou-se, através de três experimentos, a capacidade da bentonita na remediação de solos contaminados com zinco e cobre. O primeiro experimento consistiu no estudo da adsorção desses metais pela bentonita, em pH 4; 5 e 6, utilizando-se os modelos matemáticos de Langmuir e Freundlich. A partir de experimentos tipo "batch" foram elaboradas isotermas de adsorção com quantidades crescentes de zinco e cobre (5; 10; 20; 30; 50; 100; 150 e 200 mg L"1); o segundo experimento consistiu no estudo da mobilidade de zinco e cobre em colunas de lixiviação, preparadas com solo e doses crescentes de bentonita (0; 30 e 60 t ha"1). Os parâmetros de transporte foram calculados através do modelo computacional DISP. No último experimento avaliou-se, em casa de vegetação, o efeito das doses de zinco e cobre (50; 250 e 450 mg kg"1) e de bentonita (0; 30 e 60 t ha"1), adicionados ao solo, na produção de fitomassa e composição mineral do feijoeiro. Terminado o experimento (65 dias), foram determinadas as concentrações do zinco e do cobre nas partes aéreas e nas raízes das plantas e no solo das unidades experimentais, cujos resultados permitiram concluir que a incorporação de bentonita ao solo aumentou a adsorção do zinco e do cobre e que esta adsorção é dependente do pH da solução; que os modelos de Langmuir e Freundlich se apresentaram adequados para descrever a adsorção desses metais; que o tamanho das partículas da bentonita não influenciou na adsorção e a incorporação de bentonita ao solo contribuiu para diminuir a concentração e o acúmulo dos metais zinco e cobre, nas plantas de feijão-macassar. / The contamination of soil by heavy metais has been a growing problem to the environment and to the people's health in function of their toxicity, that has induced the science to search alternatives to prevent, or at least, minimize the pollutant effects of those metais or still, remediate the already polluted environment. Thus, several studies using sorbent materiais are conducted aiming to reduce the pollution problems produced by the excess of heavy metais. It is important to know the process of adsorption of heavy metais by clay minerais, because these are capable to immobilize such metais. The present study was carried out aiming, through three experiments, to evaluate the ability of the bentonite clay on the remediation of soils contaminated with zinc and copper. The fírst experiment consisted in studying the adsorption of these metais by bentonite at pH 4; 5 and 6, using the mathematical models of Langmuir and Freundlich. Adsorption isotherms were elaborated from batch adsorption assays, with increasing zinc and copper concentrations (5; 10; 20; 30; 50; 100; 150 and 200 mg L"1); the second experiment consisted in studying the zinc and copper mobility through leaching columns, prepared with soil and increasing bentonite leveis (0; 30 and 601 ha"1). The transport parameters were calculated using the computer model DISP. Finally, a greenhouse experiment was conducted to evaluate the effects of zinc and copper (50; 250 and 450mg kg"1) and bentonite (0; 30 and 60 t ha"1) added to the soil, on the phytomass production and mineral composition of a bean plant (Vigna unguiculata.h). At the end of the experiment (65 days) the phytomass and the content of zinc and copper in the aerial part, in the roots and in the soil were determined. It was observed that the adsorption of the elements increased with the bentonite application being dependent of the pH of the solution; the two studied models are appropriate to describe the zinc and copper adsorption for the bentonite; the granulometric size of the bentonite does not influence the metais adsorption and that the application of bentonite to the soil contributed to the decrease the concentration and accumulation of the heavy metais in the bean plant.

O Ministério da Saúde, ao publicar o Pacto pela Saúde 2006, reiterou a necessidade de incorporação de práticas estruturadas de planejamento na gestão do SUS. Nesta direção, vem trabalhando no desenvolvimento do PlanejaSUS – Sistema de Planejamento do SUS, com o propósito de consolidar o processo de institucionalização do planejamento no SUS. O objetivo geral do estudo buscou analisar o processo de incorporação do Plano Municipal de Saúde enquanto uma tecnologia de gestão na Secretaria Municipal de Saúde de Salvador. A estratégia escolhida para a investigação foi o estudo de caso. O modelo teórico desenvolvido pela pesquisa contemplou a integração entre os elementos dos Triângulos de Governo e de Ferro da Gestão e as variáveis envolvidas no processo de inovações em organizações, bem como a discussão do Postulado da Coerência. A pesquisa utilizou os dados produzidos durante o processo de monitoramento da implantação/implementação das ações do Plano Municipal de Saúde 2006-2009 desenvolvido pela Secretaria Municipal de Saúde, bem como daqueles obtidos mediante análise documental e observação participante. Os resultados indicaram que no período do estudo o processo não chegou à fase de rotinização, também conhecida como institucionalização, quando o Plano Municipal de Saúde seria incorporado nas atividades regulares da organização. Nesse processo foi possível a identificação de elementos facilitadores e dificultadores. A incorporação do Plano como tecnologia de gestão aponta na direção da mudança das práticas de trabalho, assim como da constituição de sujeitos implicados técnica e politicamente no trabalho da gestão. / Salvador

The objective of this thesis is to analyze legal framework of companies in private international law with focus on cross-border mobility of companies in the EU. The work consists of an introduction, five chapters and a conclusion. In the first chapter, the basic terminology used in the work and terms of private international law, collision standards, legal entities (persons) and companies are presented and defined. The second chapter is devoted to the personal statute of company and analyzes main theories of determining a personal statute - the incorporation theory and the real seat theory, their advantages and disadvantages are discussed and their comparison is mentioned at the end of the chapter. Incorporation theory enables cross-border transfer of company seats and defines law applicable to company forever, real seat theory has a protective function. Whereas incorporation theory uses the foundation of a company to determine applicable law, real seat theory uses the real seat of a company, the actual place where the company centers its activity. The third chapter discusses the subject from the point of view of the EU law. The freedom of establishment as legal basis for the movement of companies within EU is analyzed as well as basic articles of primary law regarding right of establishment....

Environmental education (EE) as an approach to all education is needed to be incorporated in all the subjects of the school curriculum. In Namibia, there are Ministerial documents that support the incorporation of education About, In/ Through and For the environment within the curriculum. Even though there are documents that support this, EE continues to suffer barriers that hinder its effective incorporation into the curriculum. The findings reveal that EE in Namibia is incorporated into the traditional environmental subject homes only. The barriers that prevent the incorporation of EE into the Namibian broad curriculum for secondary schools are, amongst others, the lack of adequate teacher education programmes and the lack of interdepartmental collaboration at school level. These barriers and many others have been identified and discussed in detail in this investigation. Measures are recommended to ensure effective incorporation of EE in the Namibian broad curriculum for secondary schools. / Educational Studies / M. Ed. (Environmental Education)

In order to increase the waste loading efficiency of nuclear waste glasses, alternative composite structures are sought that trap molybdenum in a water-durable CaMoO4 phase. In this thesis, the formation and stability of CaMoO4 in a borosilicate glass against the attack of internal radiation was investigated. It is a fundamental study that simplified the composition to known contributors of molybdate speciation, and further splits the com- ponents of α and β-decay into integral parts that replicated both nuclear and electronic interactions. Irradiation experiments using 2.5 MeV β, 7 MeV Au, and 92 MeV Xe ions were enlisted to test the hypotheses of whether 100−1000 years of radiation damage given current waste loading standards would: (i) induce phase separation in homogeneous re- gions, (ii) increase the extent of existing phase separation, (iii) induce local annealing that could cause amorphisation of crystalline phases or increase mixing between amorphous phases, or (iv) cause some combination of the above. Results from XRD, SEM, EPR, and Raman spectroscopy suggest that powellite is stable against replicated radiation damage with only minor modifications observed. The main mechanisms of alteration involved: (i) thermal and defect-assisted diffusion, (ii) relaxation from the added ion’s energy, (iii) localised damage recovery from ion tracks, and (iv) the accumulation of point defects or the formation of voids that created significant strain, and led to longer-range modifications. It can be further concluded that no precip- itation or increased phase separation was observed in single-phased glasses. In isolated cases, radiation-induced precipitation of CaMoO4 occurred, but these crystallites were reamorphised at higher doses. At high SHI fluences, minor amorphisation of powellite was also observed, but this occurred alongside bulk-to-surface reprecipitation of CaMo- species. Overall, the components of internal radiation were often found to have opposing effects on the alteration of Si−O−B mixing in the glass, ion migration, and crystallite size. This led to the prediction that a steady-state damage structure could form from cumulative decay processes. These results suggest that CaMoO4 containing borosilicate GCs are resistant to radiation, and that excess molybdenum from increased waste loading can be successfully incorporated into these structures without altering the overall dura- bility of the wasteform. Furthermore, the identified saturation in modifications occurring around 8 x 10¹⁴ Xe ions/cm² can be used as a benchmark in future investigations on more complex systems where the maximum damage state is required.

This thesis examines the working lives of foreign-born academics who come to work to the UK. Its main aim is to understand the degree and conditions of migrant scholars' inclusion in professional practice abroad. The thesis fulfils this aim by developing a conceptual approach to encapsulate how migrant professionals' working lives are conditioned by the pre-existing professional structures. Grounded in the principle of social closure, this framework proposes that migrant professionals' employment abroad is influenced by the different forms and rules of closure, as well as by the sites in which closure rules are applied. The synthesis of the theoretical framework with findings from sixty-two interviews with foreign-born scholars employed in thirteen British universities shows that migrant academics' working lives are explained by ‘modes of incorporation'. ‘Modes of incorporation' designate the distinct ways in which the academic profession has reacted to the increased presence of foreign incomers, and comprise integration, exclusion, subordination and indifference. The proposed framework extends the understanding of the demographic change in professions, and offers a way to capture migrant professionals' movement across countries.

Through a brief methodological discussion about the Ergonomic Work Analysis and a bibliographical revision about undertaken ergonomic interventions, it was verified that the results of work transformation through Ergonomic Work Analysis not always will be positive. Consequently, this work had an objective of analyzing an ergonomic intervention accomplished in a powdered detergent company, due to understand how ergonomic actions are incorporated for the different social actors and how the company, through the management, could appropriate of the results in behalf of the production. The process of activity transformation of the Vincador, from the initial demand for recommendations implemetation and validation, as well as the established social relationships and the Vincadores roles, managers, Internal Committee of Ergonomics and the company were analyzed under the Ergonomic Work Analysis point of view. The results showed that Vincadores work rhythm has increased after the ergonomic recommendations implemetation as a consequence of management s appropriation of regulations margins, whose intention was to increase the process effectiveness without considering the balance between health versus productivity. The non-incorporation of the activity point of view helped, therefore, that changes of interests, values and the involved actors logic s, lead to commitment break, before firmed among those, turning the new situation noxious for the Vincadores health. / As recentes alterações no mundo do trabalho modificaram e ampliaram o campo de atuação da ergonomia. Através de uma breve discussão metodológica sobre a Análise Ergonômica do Trabalho (AET) e uma revisão bibliográfica sobre intervenções ergonômicas empreendidas, pôde-se constatar que os resultados da transformação do trabalho pela AET nem sempre serão positivos. Diante deste cenário, este trabalho teve como objetivo analisar uma intervenção ergonômica realizada em uma empresa de detergente em pó, para compreender como as ações ergonômicas são incorporadas pelos diferentes atores sociais e como a empresa, através da gerência, pode se apropriar dos resultados obtidos em benefício apenas da produção. O processo de transformação da atividade do Vincador, desde a demanda inicial até a implementação e validação das recomendações, assim como as relações sociais estabelecidas e o papel dos Vincadores, dos gerentes, do Comitê Interno de Ergonomia e da empresa foram analisados sob o ponto de vista da AET. Os resultados mostraram que após a implementação das recomendações ergonômicas, ocorreu a intensificação do ritmo de trabalho dos Vincadores como conseqüência da apropriação das margens de regulação pela gerência, que visava a maior eficácia do processo sem considerar o equilíbrio saúde versus produtividade. A não incorporação do ponto de vista da atividade possibilitou, portanto, que as mudanças de interesses, valores e lógicas dos atores envolvidos, levassem a quebra do compromisso que havia sido firmado entre esses, tornando a nova situação, nociva à saúde dos Vincadores.

It exercises both the role of law and defense of the right to benefits, divided into these materials and regulatory benefits. In a normative activity of real estate has proven to be an effective instrument of access to decent housing. It is an activity which is characterized by the construction and sale, total or partial, of real estate units autonomous being constructed or still under construction. And why involve the disposal of future thing, the incorporative business presents a high risk of loss to the purchasers, which can be alleviated significantly with the adoption of the appropriated assets of the real estate regime, instrument that is characterized by the segregation of the net assets of each incorporation of general assets of the developer. It protects the purchaser of the real estate unit against any bankruptcy or insolvency civil of the developer, or undue delay in execution of work. Occurring of these situations, the general meeting shall decide the buyer or the continuation of the work by the liquidation of net assets. In either case, the developer is away from the direction of the project and representatives commission of the purchasers assumes administration of the enterprise affected, if feasible the construction, continue execution of the work, or liquidate the net assets of their incorporation affected. However, as the regime of affectation is of optional implantation, the discretion of the developer, it needs stimulus to offset the restrictions arising from the regime of affectation. For this purpose, the special tax regime was instituted for such appropriated assets, with the aim of simplifying and reducing the tax burden of affected incorporation in relation to federal taxes levied on the incorporative activity, compared with the usual forms of taxation by the developer of real income regime or the presumed profit regime. / O direito à moradia é considerado um direito humano, porque reconhecido pelo direito internacional, e um direito social fundamental, porque se encontra previsto na Constituição Federal. Ele exerce, simultaneamente, a função de direito de defesa e de direito a prestações, estas divididas em prestações materiais e normativas. Na esfera normativa, a atividade de incorporação imobiliária tem demonstrado ser um eficaz instrumento de acesso à moradia digna. Trata-se de atividade que se caracteriza pela construção e alienação, total ou parcial, de unidades imobiliárias autônomas a serem construídas ou em construção. E por envolver a alienação de coisa futura, o negócio incorporativo apresenta elevado risco de perdas para os adquirentes, que pode ser significativamente minorado com a adoção do regime do patrimônio de afetação da incorporação imobiliária, instrumento que se caracteriza pela segregação do acervo patrimonial de cada incorporação do patrimônio geral do incorporador. Ele protege o adquirente da unidade imobiliária contra eventual falência ou insolvência civil do incorporador, ou de atraso injustificado na execução da obra. Ocorrendo uma dessas situações, a assembleia geral dos adquirentes decidirá pelo prosseguimento da obra ou pela liquidação do acervo patrimonial. Em qualquer dos casos, o incorporador é afastado da direção do empreendimento e a comissão de representantes dos adquirentes assume a administratação do empreendimento afetado para, se viável a construção, continuar a execução da obra, ou liquidar o acervo patrimonial da respectiva incorporação afetada. Entretanto, como o referido regime de afetação é de implantação opcional, ao alvedrio do incorporador, este necessita de estímulos para compensar as restrições decorrentes do regime de afetação. Para esse fim, foi instituído o regime especial de tributação para o referido patrimônio de afetação, com o objetivo de simplificar e reduzir a carga tributária da incorporação afetada, em relação aos tributos federais incidentes sobre a atividade incorporativa, quando comparada com as formas de tributação normal do incorporador pelo regimes de lucro real ou pelo regime de lucro presumido.

The rate at which articles gets published grows exponentially and the possibility to access texts in machine-readable formats is also increasing. The need of an automated system to gather relevant information from text, text mining, is thus growing. The goal of this thesis is to find a biologically relevant gene network for atherosclerosis, themain cause of cardiovascular disease, by inspecting gene cooccurrences in abstracts from PubMed. In addition to this gene nets for yeast was generated to evaluate the validity of using text mining as a method. The nets found were validated in many ways, they were for example found to have the well known power law link distribution. They were also compared to other gene nets generated by other, often microbiological, methods from different sources. In addition to classic measurements of similarity like overlap, precision, recall and f-score a new way to measure similarity between nets are proposed and used. The method uses an urn approximation and measures the distance from comparing two unrelated nets in standard deviations. The validity of this approximation is supported both analytically and with simulations for both Erd¨os-R´enyi nets and nets having a power law link distribution. The new method explains that very poor overlap, precision, recall and f-score can still be very far from random and also how much overlap one could expect at random. The cutoff was also investigated. Results are typically in the order of only 1% overlap but with the remarkable distance of 100 standard deviations from what one could have expected at random. Of particular interest is that one can only expect an overlap of 2 edges with a variance of 2 when comparing two trees with the same set of nodes. The use of a cutoff at one for cooccurrence graphs is discussed and motivated by for example the observation that this eliminates about 60-70% of the false positives but only 20-30% of the overlapping edges. This thesis shows that text mining of PubMed can be used to generate a biologically relevant gene subnet of the human gene net. A reasonable extension of this work is to combine the nets with gene expression data to find a more reliable gene net.

Industry sector is of great importance for economic development in every country. However, increasing discussions about environmental impacts led to strategies to minimize its effects, optimize production and technology, in a search for a process capable of superior production and lesser impact on nature. This thesis proposes development and analysis of supports for production of ceramic plates of a semi-porous kind (BIIb class), with water absorption between 6 -10%, and porcelain plates, with water absorption smaller than 0.5%. Inside the supports, we incorporated solid residues from the primary treatment of brine to be electrolyzed for production of caustic soda, hydrogen, and chlorine, using dry technology. The study was conducted from a partnership between industries from thermoplastic resin and ceramic plates production. Nowadays, Solid Residue from Brine Treatment (SRBT) is reinjected in salt mines which, although environmentally adequate, might not be the best solution. Therefore, we believe that SRBT incorporation at ceramic plate´s support is a viable alternative for better destination of this chemical residue that allows lower consumption of nature´s non-renewable resources and brings advantages to the support. This study generated 954 test subjects to verify the influence of different temperatures and SRBT concentrations in processing and densification using different tests. We test apparent density, linear retraction, water absorption, flexure strength, extraction expansion, black-heart formation, humidity expansion, thermal dilation coefficient and water loss in high temperatures. After the subject characterization, we gather that SRBT did not alter the main features of the material before burning, as presented by apparent density and mechanical strength tests. In all tested concentrations, rejects brought specific gains to mechanical strength especially for subjects of BIIb class. We infer that SRBT application in ceramic plates support is viable if one takes cautionary measures regarding homogenization of the material. / O setor industrial é de grande importância para o desenvolvimento econômico em todos os países. No entanto, discussões crescentes sobre os impactos ambientais levaram a estratégias para minimizar seus efeitos, otimizar a produção e a tecnologia, em busca de um processo capaz de produzir com qualidade superior e menor impacto sobre a natureza. Esta tese propõe o desenvolvimento e análise de suportes para produção de placas cerâmicas semi-porosas (classe BIIb), com absorção de água entre 6-10% e placas de porcelana, com absorção de água menor que 0,5%. Dentro dos suportes, incorporamos resíduos sólidos do tratamento primário de salmoura a ser eletrolisado para produção de soda cáustica, hidrogênio e cloro, utilizando tecnologia seca. O estudo foi realizado a partir de uma parceria entre indústrias de resinas termoplásticas e produção de placas cerâmicas. Atualmente, o Resíduo Sólido de Tratamento de Salmoura (RSTS) é reinjetado em minas de sal que, embora ambientalmente adequadas, podem não ser a melhor solução. Por isso, acreditamos que a incorporação da RSTS no suporte de placas cerâmicas é uma alternativa viável para melhor destinação desse resíduo químico que permite menor consumo dos recursos não renováveis da natureza e traz vantagens ao suporte. Este estudo gerou 954 corpos de teste para verificar a influência de diferentes temperaturas e concentrações de RSTS no processamento e densificação usando diferentes testes. Testamos densidade aparente, retração linear, absorção de água, resistência à flexão, expansão de extração, formação de coração negro, expansão de umidade, coeficiente de dilatação térmica e perda de água em altas temperaturas. Após a caracterização, concluímos que o RSTS não alterou as principais características do material antes da queima, como apresentado pelos testes de densidade aparente e resistência mecânica. Em todas as concentrações testadas, os rejeitos trouxeram ganhos específicos para a resistência mecânica, especialmente para corpos da classe BIIb. Infere-se que a aplicação da RSTS em placas cerâmicas de suporte é viável, caso se tomem medidas de cautela quanto à homogeneização do material.
