Microemulsions have been studied in the extraction of heavy metals from aqueous solutions. Considering the problems related with the sediment resulting from the tanning process, due to its high content in chromium, in this work this sediment was characterized and microemulsion systems were applied for chromium removal. The extraction process consists in the removal of heavy metal ions present in an aqueous feeding solution (acid digestion solution) by a microemulsion system. First three different solid sludge digestion methods were evaluated, being chosen the method with higher digestion capacity. For this digestion method, seeking its optimization, was evaluated the influence of granule size, temperature and digestion time. Experimental results showed that the method proposed by USEPA (Method A) was the most efficient one, being obtained 95.77% of sample digestion. Regarding to the evaluated parameters, the best results were achieved at 95?C, 14 Mesh granule size, and 60 minutes digestion time. For chromium removal, three microemulsion extraction methods were evaluated: Method 1, in a Winsor II region, using as aqueous phase the acid digestion solution; Method 2, in a Winsor IV region, being obtained by the addition of the acid digestion solution to a microemulsion phase, whose aqueous phase is distilled water, until the formation of Winsor II system; and Method 3, in a Winsor III region, consisting in the formation of a Winsor III region using as aqueous phase the acid digestion solution, diluted in NaOH 0.01N. Seeking to optimize the extraction process only Method 1 (Systems I, II, and VIII) and Method 2 (System IX) were evaluated, being chosen points inside the interest regions (studied domains) to study the influence of contact time and pH in the extraction percentiles. The studied systems present the following compositions: System I: Surfactant Saponified coconut oil, Cosurfactant 1-Butanol, Oil phase Kerosene, Aqueous phase 2% NaCl solution; System II: Aqueous phase Acid digestion solution with pH adjusted using KOH (pH 3.5); System VIII: Aqueous phase - Acid digestion solution (pH 0.06); and System IX Aqueous phase Distilled water (pH 10.24), the other phases of Systems II, VIII and IX are similar to System I. Method 2 showed to be the more efficient one regarding chromium extraction percentile (up to 96.59% - pH 3.5). Considering that with Method 2 the microemulsion region only appears in the Winsor II region, it was studied Method 3 (System X) for the evaluation and characterization of a triphasic system, seeking to compare with a biphases system. System X is composed by: Surfactant Saponified coconut oil, Cosurfactant 1-Butanol, Oil phase Kerosene, Aqueous phase Acid digestion solution diluted with water and with its pH adjusted using 0.01N NaOH solution. The biphasic and triphasic microemulsion systems were analyzed regarding its viscosity, extraction efficiency and drop effective diameter. The experimental results showed that for viscosity studies the obtained values were low for all studied systems, the diameter of the drop is smaller in the Winsor II region, with 15.5 nm, reaching 46.0 nm in Winsor III region, being this difference attributed to variations in system compositions and micelle geometry. In chromium extraction, these points showed similar results, being achieved 99.76% for Winsor II system and 99.62% for Winsor III system. Winsor III system showed to be more efficient due to the obtaining of a icroemulsion with smaller volume, with the possibility to recover the oil phase in excess, and the use of a smaller proportion of surfactant and cosurfactant (C/S) / Os curtumes geram efluentes carregados em metais pesados, especialmente o cromo, utilizado no processo de curtimento. Microemuls?es t?m sido estudadas na remo??o de metais pesados. Considerando o problema encontrado no sedimento gerado no processo de curtimento, pelo elevado teor de cromo, no presente trabalho nos propomos a caracteriz?-lo e aplicar sistemas microemulsionados para remo??o do cromo. O processo de extra??o consiste em remover o metal de uma alimenta??o aquosa (solu??o ?cida digerida) para uma fase microemuls?o. Iniciou-se a pesquisa avaliando tr?s diferentes m?todos de digest?o de sedimentos, escolhendo-se o m?todo que apresentasse maior percentual de digest?o, sendo este m?todo otimizado atrav?s de mudan?as no di?metro das part?culas do sedimento, tempo e temperatura de digest?o. Nesse estudo, escolheu-se o m?todo proposto pelo EPA (M?todo A), que se mostrou mais eficiente, obtendo-se um percentual de 95,77% de digest?o da amostra. Com rela??o aos par?metros avaliados, os melhores resultados foram obtidos com a temperatura a 95?C, granulometria de 14 Mesh e tempo de opera??o de 60 minutos. Para os estudos da extra??o foram utilizados tr?s m?todos: o M?todo 1, que consiste na forma??o de uma regi?o de Winsor II, utilizando a solu??o ?cida digerida como fase aquosa; o M?todo 2, que consiste em utilizar uma microemuls?o cuja fase aquosa ? ?gua destilada e adicionar a solu??o ?cida digerida at? a obten??o de um sistema de Winsor II; e o M?todo 3, que consiste na forma??o de uma regi?o de Winsor III, utilizando a solu??o ?cida digerida, dilu?da em NaOH 0,01N, como fase aquosa. Para o estudo da otimiza??o da extra??o foram avaliados apenas os M?todos 1 (Sistemas I, II e VIII) e 2 (Sistema IX), escolhendo-se pontos dentro das regi?es de interesse (dom?nio estudado) para estudar a influ?ncia do tempo e do pH no percentual de extra??o. Os sistemas estudados apresentam as seguintes composi??es: Sistema I: Tensoativo ?leo de coco saponificado, Cotensoativo 1-Butanol, Fase oleosa Querosene, Fase aquosa NaCl 2,0%; Sistema II: Fase aquosa Solu??o ?cida digerida ajustada c/ KOH (pH 3,5); Sistema VIII: Fase aquosa Solu??o ?cida digerida (pH 0,06) e Sistema IX: Fase aquosa ?gua destilada (pH 10,24), as demais fases dos Sistemas II, VIII e IX s?o semelhantes ao Sistema I. Atrav?s desse estudo, observou-se que o M?todo 2 foi mais eficiente, com percentuais de 96,59% de extra??o, em pH 3,5. Tendo em vista que com a aplica??o do M?todo 2 s? se obt?m os sistemas de Winsor II, estudou-se um sistema capaz de fornecer a regi?o de Winsor III (tr?s fases) para efeito de compara??o da efici?ncia na extra??o do cromo, com um sistema de duas fases (Winsor II) e, assim, constituiu-se o M?todo 3, utilizando o Sistema X. O sistema X apresenta a seguinte composi??o: Tensoativo ?leo de coco saponificado, Cotensoativo 1-Butanol, Fase oleosa Querosene, Fase aquosa Solu??o ?cida digerida dilu?da em ?gua e ajustado com NaOH 0,01N. As microemuls?es nas regi?es bif?sicas e trif?sicas foram analisadas com rela??o ? viscosidade, extra??o e di?metro efetivo da gota. Os resultados obtidos nas regi?es de W II e WIII foram os seguintes: a viscosidade ? baixa em todos os pontos estudados e o comportamento dos fluidos ? do tipo Newtoniano; o di?metro da gota ? menor na regi?o de Winsor II, com di?metro de 15,5 nm, atingindo 46 nm em Winsor III, sendo essa varia??o atribu?da ?s composi??es estudadas e ? geometria da micela; os resultados obtidos na extra??o com os dois sistemas foram semelhantes, com 99,76% de extra??o em WII e 99,62 % em WIII. O sistema utilizando WIII mostrou-se mais eficiente na extra??o do cromo devido a obten??o de uma microemuls?o com menor volume, a possibilidade de recuperar o ?leo em excesso e a utiliza??o de uma menor propor??o de cotensoativo e tensoativo (C/T)

In the late 90 s an alternative and low cost method was proposed from alkaline hydrothermal synthesis of nanotubes. Based on this context, the objective of this work was to prepare different materials based on TiO2 anatase using hydrothermal synthesis method proposed by Kasuga and submit them to an acid wash treatment, in order to check the structural behavior of final samples. They were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), adsorption/desorption of N2, thermal analysis (TG/DTA) and various spectroscopic methods such as absorption spectroscopy in the infrared (FT-IR), Raman spectroscopy and X-ray photoelectron spectroscopy (XPS). All the information of characterizations confirmed the complete conversion of anatase TiO2 in nanotubes titanates (TTNT). Observing the influence of acid washing treatment in titanates structure, it was concluded that the nanotubes are formed during heat treatment, the sample which was not subjected to this process also achieved a complete phase transformation, as showed in crystallography and morphology results, however the surface area of them practically doubled after the acid washing. By spectroscopy was performed a discussion about chemical composition of these titanates, obtaining relevant results. Finally, it was observed that the products obtained in this work are potential materials for various applications in adsorption, catalysis and photocatalysis, showing great promise in CO2 capture / Materiais nanoestruturados t?m se difundido com sucesso ao longo dos ?ltimos anos, isso devido ao seu tamanho e propriedades incomuns, resultando em um crescimento exponencial das atividades de investiga??o dedicadas ? nanoci?ncia e nanotecnologia, o que tem estimulado a procura por diferentes m?todos que possam controlar as principais propriedades dos nanomateriais a fim de adequ?-los para aplica??es de alto valor agregado. No final da d?cada de 90 um m?todo alternativo e de baixo custo foi proposto a partir da s?ntese hidrot?rmica alcalina de nanotubos. Baseando-se nesse contexto, o objetivo deste trabalho foi preparar diferentes materiais ? base de TiO2 anatase utilizando o m?todo de s?ntese hidrot?rmica proposto por Kasuga e submet?-los em seguida a um tratamento de lavagem ?cida, com o prop?sito de verificar o comportamento estrutural das amostras finais. Essas foram caracterizadas por difratometria de raios X (DRX), microscopia eletr?nica de varredura (MEV), microscopia eletr?nica de transmiss?o (MET), adsor??o/dessor??o de N2, an?lise t?rmica (ATG/ATD) e diferentes m?todos espectrosc?picos como, espectroscopia de absor??o na regi?o do infravermelho (FT-IR), espectroscopia Raman e espectroscopia fotoeletr?nica de raios X (XPS). O conjunto de caracteriza??es se complementou, confirmando a transforma??o completa do TiO2 anatase de partida em titanatos nanotubulares (TTNT). Ao observar a influ?ncia que o tratamento de lavagem ?cida exerce na estrutura do mesmo, conclui-se que os nanotubos s?o formados durante o tratamento t?rmico, pois a amostra que n?o foi submetida ao processo tamb?m alcan?ou uma transforma??o completa de fase, conforme os resultados de cristalografia e morfologia, entretanto a ?rea espec?fica deles ? praticamente dobrada ap?s a lavagem ?cida. Por espectroscopia foi realizada uma minusiosa discuss?o acerca da composi??o qu?mica desses titanatos, obtendo resultados relevantes. Por fim, ressalta-se que os produtos obtidos nesse trabalho s?o materiais com potencial para diferentes aplica??es em adsor??o, cat?lise e fotocat?lise, se mostrando promissores na captura do CO2

The thesis examines how the social construction of African women in development discourse transformed from the 1970s to the 2000s, focusing in particular on the Canadian International Development Agency (CIDA). From the 1970s to the 1990s representations of African women were based on women’s economic potential. The mainstreaming of gender in the 1990s resulted in women being represented as agents of change. This approach gave women an opportunity to play roles in decision-making but led to policies that failed to challenge the established institutions. The emphasis on women as agents of change opened doors to some African women but with implications for the women’s movement. Only some middle-class women appear to benefit but their gains have been marginal in comparison to the gender inequalities that persist. The thesis uses secondary sources and interviews with development practitioners in Ottawa to understand the representation of African women as agents of change.

During the past decade, international development discourse has shifted from a narrow focus on aid effectiveness to one of cooperation towards more effective development. A series of High Level Forums have produced a set of principles to guide this new development framework. With the steady increase of international migration, sizeable diasporas who generate a diversity of activities with development implications in their homelands have formed outside of developing countries. Recognizing their importance and potential for development, several developed country bilateral donors have engaged these emerging development actors, including the Canadian International Development Agency (CIDA), the United Kingdom’s Department for International Development (DFID), and the United States Agency for International Development (USAID). Analysis of their policies and programs reveals a set of emerging themes and lessons learned that identify the need to challenge conventional ways of thinking about the nature of development partnerships in order to move towards more effective development.

With the possible chance to vary various factors at once to see if any one factor was significant enough in the answers, experimental planning was used. Microwave assisted digestion allows, through the application of potency, an increasing number of collisions between the HNO3 and H2O2 molecules, favoring sample opening for complex matrixes. For this, a 24 factorial experimental planning was used, varying potency, time and the volumes for HNO3 65% and H2O2 30%. To achieve the desired answers, several elements were monitored (C, Cu, Cr, Fe, Ni, Zn and V) through Inductively coupled plasma atomic emission spectroscopy (ICP-OES). With this initial study it was noticed that the HNO3 was not a significant factor for any of the statistical studies for any of the analytes and the other 3 factors and their interactions showed statistical significance. A Box Behnken experimental planning was used taking in consideration 3 factors: H2O2 volume, time (min) and Potency (W), Nitric Acid kept at 4mL for a mass of 0,1g of petroleum. The results were extremely satisfying showing higher efficiency in the digestion process and taking in a responsibility between the answers for each analyte and the carbon monitoring was achieved in the following conditions: 7mL of H2O2, 700 Watts of potency and a reaction time of 7 minutes with 4mL de HNO3 for a mass of 0,1g of petroleum. The optimized digestion process was applied to four different petroleum samples and the analytes determined by ICP-OES / Este trabalho teve como objetivo a otimiza??o de uma metodologia que possibilite maior efici?ncia no processo de digest?o auxiliada por forno microondas para amostras de petr?leo. Um planejamento experimental multivariado foi realizado, num intuito de observar todos os fatores ao mesmo tempo e suas intera??es, para saber se determinado fator tem influ?ncia significativa sobre a resposta. A digest?o auxiliada por microondas permite, atrav?s da aplica??o de pot?ncia, tornar maior o n?mero de colis?es entre as mol?culas do HNO3 e do H2O2 no meio reacional, favorecendo a abertura de amostras de matrizes complexas. Dessa forma, foi realizado um planejamento fatorial 24 variando a pot?ncia, o tempo e os volumes de HNO3 65% V/V e H2O2 30% V/V. Para obter as respostas, foram monitorados diversos elementos (C, Cu, Cr, Fe, Ni, Zn e V) por espectrometria de emiss?o ?tica com plasma indutivamente acoplado (ICP-OES). Com este estudo inicial foi observado que o volume de HNO3 n?o foi um fator significativo estatisticamente para nenhum dos analitos estudados e que os outros tr?s fatores e suas intera??es apresentaram signific?ncia estat?stica. Um segundo planejamento do tipo Box Behnken foi realizado considerando os 3 fatores: volume de H2O2, tempo (min) e pot?ncia (W), o volume de ?cido n?trico foi mantido em 4 mL para uma massa de 0,1g de petr?leo. Os resultados foram bastante expressivos, a maior efici?ncia de digest?o, assumindo um compromisso entre as respostas obtidas para cada analito e o monitoramento do carbono, foi obtido nas condi??es de 7 mL de H2O2, 700 W de pot?ncia e 7 min de tempo de rea??o com 4 mL de HNO3 para uma massa de 0,1 g de petr?leo. O procedimento de digest?o otimizado foi aplicado a quatro diferentes amostras de petr?leo e os analitos determinados por ICP OES

Gaucher Disease (GD) is a hereditary lysosomal storage disorder characterized by the accumulation of glucosylceramide, mainly in the cells of the reticuloendothelial system, due to a deficiency of the enzyme acid &#946;-glucosidase (GBA). Diagnosis is usually based on measurement of GBA activity in peripheral leukocytes. The purpose of this study was to evaluate the ability of screening for GBA and chitotriosidase activity using Dried Blood Spots on Filter Paper (DBS-FP) to identify individuals at high risk for GD in high-risk populations such as that of Tabuleiro do Norte, a small town in Northeastern Brazil. Methods. Between June 1, 2007 and May 31, 2008, 740 consented residents and descendants of traditional families from Tabuleiro do Norte were submitted to screening with DBS-FP. Subjects with GBA activity <2.19 nmol/h/mL were referred to analysis of GBA and chitotriosidase activity in peripheral leukocytes and in plasma, respectively. Subjects at highest risk for GD (GBA activity in peripheral leukocytes <5.6 nmol/h/mg protein) were submitted to molecular analysis to confirm diagnosis. Results. Screening with DBS-FP identified 135 subjects (18.2%) with GBA activity <2.19 nmol/h/mL, 131 of whom remained in the study. In 10 of these (7.6%), GBA activity in leukocytes was 2.6 5.5 nmol/h/mg protein. Subsequent molecular analysis confirmed 6 cases of heterozygosity and 4 normals for GD. Conclusion. DBS-FP assay was shown to be an effective initial GD screening strategy for high-prevalence populations in developing regions. Diagnosis could not be established from GBA activity in leukocytes alone, but required confirmation with molecular analysis / A doen?a de Gaucher (DG) ? uma patologia de dep?sito de gordura nos lisossomos, de heran?a autoss?mica recessiva, caracterizada pelo ac?mulo do substrato glicosilceramida, principalmente nas c?lulas do sistema reticuloendotelial, em raz?o da defici?ncia da enzima &#946;-glicosidase ?cida (GBA). O diagn?stico, comumente, ? feito pela dosagem da atividade da GBA em leuc?citos perif?ricos. Tabuleiro do Norte (TN), Cear?, Brasil, ? um munic?pio com cerca de 28.000 habitantes com a preval?ncia da DG de 1:4.000 habitantes, possivelmente a mais elevada do Brasil. O objetivo da disserta??o ? avaliar o rastreamento para DG realizado em TN com base na an?lise das atividades enzim?ticas da GBA e da quitotriosidase em amostras Sangue Seco em Papel de Filtro (SSPF). Entre 01 de junho de 2007 a 31 de maio de 2008, 740 indiv?duos residentes e descendentes de fam?lias de TN participaram do rastreamento para DG a partir de amostras de SSPF. Indiv?duos com atividade GBA<2,19 nmol/h/mL foram selecionados para an?lise da atividade da GBA e da quitotriosidase em leuc?citos perif?ricos e no plasma, respectivamente. Os indiv?duos com maiores riscos de DG (atividade de GBA em leuc?citos perif?ricos <5,6 nmol/h/mg de prote?na) foram referenciados para an?lise molecular para confirma??o diagn?stica. A triagem com amostras de SSPF identificou 135 indiv?duos (18,2%) com atividade da GBA<2,19 nmol/h/mL, dos quais 131 permaneceram no estudo. Em dez destes (7,6%), a atividade da GBA em leuc?citos variou de 2,6-5,5 nmol/ h/mg de prote?na, considerados suspeitos da DG. A an?lise molecular subsequente revelou, entretanto, que se tratava de seis indiv?duos heterozigotos para a muta??o G377S e, em quatro deles, n?o foram identificadas muta??es da DG. A an?lise enzim?tica de amostras de SSPF mostrou ser uma estrat?gia eficaz de triagem da DG em popula??es com alto risco, mas a medida da atividade da GBA em leuc?citos deve ser realizada para confirma??o diagn?stica. O diagn?stico de DG em indiv?duos assintom?ticos n?o deve ser firmado baseando-se apenas na an?lise da atividade da GBA em leuc?citos, sendo necess?ria, tamb?m, a confirma??o diagn?stica pela an?lise molecular

Social control, as the Constitution of 1998, indicates the possibility of doing a social relationship between state and society, in a public and democratic basis, to expand the access to basic health services through the popular participation in the Councils and Health Conference. This way, the effective participation of the people shows the struggle for a larger democracy, citizenship and consequently of public social policies, to express the possibility of breaking with the meritocratic profile, costumer and their exclusion. So, the study tried to know the process of participation of users in the health policy in Goiânia, through the City Council and Health Conference, while that period. For better understanding this study in an empirical reality, it was done a semi-structured interview for data collection, with questions guiding the research and allowing new ones. This increased the research by putting the interviewees free to express their opinion. After data collection and systematization of the answers applied to each interviewed person, there was a correlation between theoretical and empirical research in making the knowledge of the object, mediated by critical analysis. / A proposta deste estudo é apreender o processo histórico do Sistema Único de Saúde em Goiânia e, nele, o controle social, sua implantação e implementação, em duas gestões distintas: de 1988 a 1992, gestão do PMDB, e a segunda, de 1993 a 1996, do PT. O controle social, conforme a Constituição de 1998 indica a possibilidade de construção de uma sociabilidade no campo da relação Estado e sociedade, em bases públicas e democráticas, no sentido de ampliação do acesso aos serviços básicos de saúde por meio da participação popular nos Conselhos e Conferências de Saúde. Nessa direção, a participação efetiva dos sujeitos expressa a luta pelo alargamento da democracia, da cidadania e, consequentemente, das políticas sociais públicas, ao expressar a possibilidade de romper com o perfil meritocrático, clientelista e excludente dessas políticas. Nesse sentido, o estudo buscou conhecer o processo de participação dos usuários na construção da Política de Saúde de Goiânia, por meio do Conselho Municipal de Saúde e Conferências, durante o período mencionado. Para maior entendimento do objeto de estudo na realidade empírica, optou-se pela entrevista semiestruturada para coleta de dados, com formulações de questões norteadoras da pesquisa, ao permitir que elas, pertinentes ao tema, fossem tratadas de forma aberta, bem como ao possibilitar novas indagações. Isso assegurou um enriquecimento à investigação, ao deixar o entrevistado livre para fazer suas colocações. Após a coleta de dados e sistematização das respostas às perguntas que compõem o roteiro de entrevista, aplicado a cada um dos sujeitos entrevistados, estabeleceu se a correlação entre a pesquisa teórica e a pesquisa empírica na construção do processo de conhecimento do objeto, mediado pela análise crítica.
