A presente dissertação é relativa aos assistentes sociais que exerceram funções de deputados em Portugal Continental, na Assembleia Nacional e na Assembleia da República Portuguesa. Procedeu-se à sua caracterização e à análise dos seus principais discursos parlamentares. A pertinência da investigação é justificada pela inexistência de trabalhos acerca da temática escolhida e pela reduzida produção académica no que respeita à vasta dimensão política do Serviço Social em Portugal. A investigação alicerçou-se numa pesquisa bibliográfica sobre os temas em foco, e documental, na análise das fichas biográficas dos deputados identificados e das transcrições textuais das sessões da Assembleia Nacional e da Assembleia da República Portuguesa, onde constam os discursos destes deputados. Estas fontes primárias estão acessíveis no sítio oficial da Assembleia da República (www.parlamento.pt). Pretende-se com este estudo abordar o lugar atribuído à Assembleia Nacional e à Assembleia da República Portuguesa nos respetivos regimes de ditadura e democracia e identificar e caracterizar académica, profissional e politicamente os assistentes sociais que exerceram estas funções. Objetiva-se ainda a análise das principais intervenções destes deputados no contexto da Assembleia Nacional e da Assembleia da República Portuguesa. Apurou-se que o número de deputadas à Assembleia Nacional e à Assembleia da República Portuguesa não variou significativamente nos regimes políticos abordados. Foram identificadas cinco deputadas à Assembleia Nacional, da V à XI legislatura (de 1949 a 1974 – 25 anos), sendo que a primeira deputada identificada exerceu funções ao longo da V e VI legislaturas da Assembleia Nacional. Após a queda do regime ditatorial e depois de 21 anos em democracia, assistentes sociais voltaram a exercer funções de deputados. Entre 1995 e 2011 exerceram funções seis deputados à Assembleia da República Portuguesa. Um deles desenvolveu atividades ao longo da X e XI legislaturas. Os resultados da investigação mostram que a maioria destes deputados são mulheres, havendo apenas um homem. Relativamente à formação académica dos deputados constatou-se que antes de 1974 o estabelecimento que formou mais assistentes sociais deputadas foi o Instituto de Serviço Social de Lisboa (3), seguido do Instituto Superior de Ciências Sociais e Políticas Ultramarinas (1) e do Instituto Superior de Serviço Social Pio XII, em Luanda (1). Os deputados à Assembleia da República formaram-se no Instituto Superior de Serviço Social de Coimbra (2); no Instituto Superior Bissaya Barreto, Coimbra (1); no Instituto Superior de Serviço Social do Porto (1); no Instituto Superior de Serviço Social de Lisboa (1) e no Instituto Superior de Serviço Social Pio XII, Luanda (1). As deputadas que exerceram funções durante o Estado Novo pertenciam à União Nacional e Acção Nacional Popular, sendo que uma delas pertencia à Ala Liberal da ANP. Quanto aos deputados que exerceram funções no período democrático percebe-se que todos eram vinculados a partidos do bloco central e da direita: uma deputada do PSD, uma do CDS e quatro deputados do PS. No que respeita às intervenções parlamentares dos deputados identificados, observou-se que as deputadas à Assembleia Nacional apresentaram e fundamentaram propostas de medidas de política social apoiando-se na sua experiência profissional, principalmente em debates em que o tema foi a família ou a pobreza. Os deputados à Assembleia da República direcionaram os seus discursos para o apoio e/ou complemento das iniciativas propostas pelo governo, pois quatro destes deputados exerceram funções enquanto o partido a que pertenciam estava na liderança do governo. Face á vastidão da temática abordada, a presente dissertação constitui-se como um primeiro contributo para a produção de bibliografia no âmbito da dimensão política do Serviço Social, reconhecendo-se a necessidade de aprofundar mais o tema. / This thesis is on social workers who acted as deputies in Portugal, on the National Assembly and the Assembly of the Portuguese Republic. Characterization and analysis of its key parliamentary speeches was the chosen procedure. The relevance of the research is justified by the lack of previous work on the chosen theme and the reduced academic outputs with respect to the vast political dimension of social work in Portugal. Research has its foundations in a literature research on the topics in focus, and also documentary, by the analysis of the biographical records of Members discussed and the verbatim transcripts of the sessions of the National Assembly and the Assembly of the Portuguese Republic, which contains the speeches of such Members. These primary sources include legislative sessions and are available on the Assembly of the Republic (www.parlamento.pt) official website. The study aims to address the place assigned to the National Assembly and the Assembly of the Portuguese Republic, regarding the respective regimes of dictatorship and democracy and to identify and characterize academically, professionally and politically, the social workers who have exercised these functions. Furthermore on the objective is the analysis of the main interventions in the context of such Members of the National Assembly and the Assembly of the Portuguese Republic. It was found that the number of deputies to the National Assembly and the Assembly of the Portuguese Republic did not significantly vary in both political regimes. Five deputies to the National Assembly were identified on the legislatures V to XI (1949-1974 - 25 years), with the first identified lady holding positions along the V and VI legislatures of the National Assembly. After the fall of the dictatorship and after 21 years of democracy, social workers returned to act as deputies. Between 1995 and 2011 held office six members of the Assembly of the Portuguese Republic. One developed activities along the X and XI legislatures of the Assembly of the Portuguese Republic. Research results show that the majority of these are women, and only one man. Regarding the academic training of the deputies, it was found that before 1974 the establishment that formed most of the social workers was, the Institute of Social Service of Lisbon (3), followed by the School of Social Science and Policy Overseas (1) and the Higher Institute of Social Service Pius XII in Luanda (1). Members of Parliament formed in the Institute of Social Service of Coimbra (2), the Higher Institute Bissaya Barreto, Coimbra (1), the Institute of Social Service of Porto (1), the Higher Institute of Social service of Lisbon (1) and the Institute of Social service Pius XII, Luanda(1). Deputies who held office during the New state belonged to the National Union and National People's Action parties, one of which belonged to the Liberal Wing of the ANP. As for the deputies who held office in the democratic period one realizes that all parties were bound to the central block and right wing: A Member of the PSD, one of CDS and four members of the PS. Regarding the parliamentary speeches of identified Members, it was noted that the National Assembly deputies presented and substantiated proposals for social policy measures relying on their professional experience, primarily on the debates in which the theme was family or poverty. Members of Parliament have directed their speeches to support and / or complement the initiatives proposed by the government, since four of these deputies exercise their functions while the party they belonged was in governmental leadership. Given the vastness of the topic addressed in this thesis, it constitutes itself as a first contribution to the production of literature within the political dimension of social work, recognizing the need to go deeper into the subject.

Composite TiO2/acid leached serpentine tailings (AST) were synthesized through the hydrolysis–deposition method and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energydispersive X-ray spectrometry (EDS), Fourier-transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and surface area measurement (BET). The XRD analysis showed that TiO2 coated on the surface of acid leached serpentine tailings was mixed crystal phases of rutile and anatase, the grain size of which is 10–30 nm. SEM, TEM, and EDS analysis exhibited that nano-TiO2 particles were deposited on the surface and internal cavities of acid leaching serpentine tailings. The XPS and FT-IR analysis demonstrated that the coating process of TiO2 on AST was a physical adsorption process. The large specific surface area, porous structure, and plentiful surface hydroxyl group of TiO2/AST composite resulted in the high adsorption capacity of Cr(VI). The experimental results demonstrated that initial concentration of Cr(VI), the amount of the catalyst, and pH greatly influenced the removal efficiency of Cr(VI). The removal kinetics of Cr(VI) at a relative low initial concentration was fitted well with Langmuir–Hinshelwood kinetics model with R2 value of about unity. The asprepared composites exhibited strong adsorption and photocatalytic capacity for the removal of Cr(VI), and the possible photocatalytic reduction mechanism was studied. The photodecomposition of Cr(VI) was as high as 95% within 2 h, and the reusability of the photocatalysis was proven.

The formation of readily recoverable and reusable organic semiconducting Cu- and AgTCNQ (TCNQ=7,7,8,8-tetracyanoquinodimethane) microstructures decorated with Pt and Pd metallic nanoparticles is described for the effective reduction of CrVI ions in aqueous solution at room temperature using both formic acid and an environmentally friendly thiosulfate reductant. The M-TCNQ (M=metal) materials were formed by electrocrystallisation onto a glassy carbon surface followed by galvanic replacement in the presence of H2PtCl6 or PdCl2 to form the composite material. It was found that loading of the surface with nanoparticles could easily be controlled by changing the metal salt concentration. Significantly, the M-TCNQ substrates facilitated the formation of well-isolated metal nanoparticles on their surfaces under appropriate galvanic replacement conditions. The semiconductor–metal nanoparticle combination was also found to be critical to the catalyst performance, wherein the best-performing material was CuTCNQ modified by well-isolated Pt nanoparticles with both formic acid and thiosulfate ions as the reductant.

Zero valent iron (ZVI) was prepared by reducing natural goethite (NG-ZVI) and synthetic goethite (SG-ZVI) in hydrogen at 550 °C. XRD, TEM, FESEM/EDS and specific surface area (SSA) and pore analyser were used to characterize goethites and reduced goethites. Both NG-ZVI and SG-ZVI with a size of nanoscale to several hundreds of nanometers were obtained by reducing goethites at 550 °C. The reductive capacity of the ZVIs was assessed by removal of Cr(VI) at ambient temperature in comparison with that of commercial iron powder (CIP). The effect of contact time, initial concentration and reaction temperature on Cr(VI) removal was investigated. Furthermore, the uptake mechanism was discussed according to isotherms, thermodynamic analysis and the results of XPS. The results showed that SG-ZVI had the best reductive capacity to Cr(VI) and reduced Cr(VI) to Cr(III). The results suggest that hydrogen reduction is a good approach to prepare ZVI and this type of ZVI is potentially useful in remediating heavy metals as a material of permeable reaction barrier.

The electronic structure of group II-VI semiconductors in the stable wurtzite form is analyzed using state-of-the-art ab initio approaches to extract a simple and chemically transparent tight-binding model. This model can be used to understand the variation in the bandgap with size, for nanoclusters of these compounds. Results complement similar information already available for same systems in the zinc blende structure. A comparison with all available experimental data on quantum size effects in group II-VI semiconductor nanoclusters establishes a remarkable agreement between theory and experiment in both structure types, thereby verifying the predictive ability of our approach. The significant dependence of the quantum size effect on the structure type suggests that the experimental bandgap change at a given size compared to the bulk bandgap, may be used to indicate the structural form of the nanoclusters, particularly in the small size limit, where broadening of diffraction features often make it difficult to unambiguously determine the structure.

Conformational energy calculations were carried out on penicillin α-and Β-sulfoxides and δ2- and δ3-cephalosporins, in order to identify the structural features governing their biological activity. Results on penicillin Β-sulfoxide indicated that in its favoured conformation, the orientation of the aminoacyl group was different from the one required for biological activity. Penicillin α sulfoxide, like penicillin sulfide, favoured two conformations of nearly equal energies, but separated by a much higher energy barrier. The reduced activity of the sulfoxides despite the nonplanarity of their lactam peptide indicated that the orientations of the aminoacyl and carboxyl groups might also govern biological activity. δ3-cephalosporins favoured two conformations of nearly equal energies, whereas δ2-cephalosporins favoured only one conformation. The lactam peptide was moderately nonplanÄr in the former, but nearly planar in the latter. The differences in the.preferred orientations of the carboxyl group between penicillins and cephalosporins were correlated with the resistance of cephalosporins to penicillinases.

Antipyrine complexes of TiO2+, ZrO2+, Zr4+, Th4+ and UO2+2 perchlorates with molecular formulae TiO(Apy)4(ClO4)2, ZrO(Apy)3(ClO4)2, Zr(Apy)6(ClO4)4, Th(Apy)7(ClO4)4 and UO2(Apy)5(ClO4)2 have been prepared and characterized. The complexes are stable in air at room temperature and decompose exothermally at ~3OO °C. The i.r. study indicates the bonding of the antipyrine to the metal ion through its carbonyl oxygen. The nature of the bonding of the perchlorate and the stereochemistry of the complexes are discussed in the light of infrared spectra, conductivity in solvents of different polarity, and molecular weight measurements. From the UO2+2 group frequencies, the force constant K and rU-o are found to be 6.29 × 105 dynes/ cm-1 and 1.74 Å, respectively.
