Eficiência mastigatória e qualidade das próteses totais confeccionadas pelas técnicas tradicionais e simplificada: um ensaio clínico

Traditional methods for dentures fabrication require a wide clinical and laboratory procedures; however, there is no scientific evidence that these methods can produce better results when compared with simplified methods. Aim: To evaluate the effectiveness of a simplified methods for denture fabrication, comparing it to the traditional one through masticatory efficiency and prosthesis quality. Method: A randomized controlled trial was conducted with 50 patients, 25 rehabilitated with prosthesis produced by traditional technique and 25 rehabilitated by a simplified technique. The masticatory efficiency was evaluated by colorimetric method, using chewing capsules. The quality of prosthesis was obtained using a reliable and reproducible instrument. Statistical analysis of the masticatory efficiency and quality of the prosthesis was obtained by the Mann-Whitney test. Results: 39 patients completed the study, 18 on traditional group and 21 on simplified group. There was no difference between groups for the masticatory efficiency (p = 0.835) and the quality of the prosthesis (p = 0672). The evaluation of the overall quality of the prosthesis according to oral conditions, demonstrated significant difference on the height of the mandibular ridges (p = 0.010) and mandibular muscle attachments (p = 0.039). Conclusion: Complete dentures fabricated by simplified method were considered effective from the point of view of masticatory efficiency and quality of prosthetics, with results similar to those made by the traditional method.

Síntese e caracterização de óxidos de zinco e de magnésio suportados em A1SBA-15 para produção de biodiesel

To overcome the challenge of meeting growing energy demand in a sustainable way, biodiesel has shown very promising as alternative energy can replace fossil fuels, even partially. Industrially, the biodiesel is produced by homogeneous transesterification reaction of vegetable oils in the presence of basic species used as catalysts. However, this process is the need for purification of the esters obtained and the removal of glycerin formed after the reaction. This context, the alternative catalysts have that can improve the process of biodiesel production, aiming to reduce costs and facilitate its production. In this study, the AlSBA-15 support with Si / Al ratio = 50 was synthesized, as like as the heterogeneous catalysts of zinc oxide and magnesium supported on mesoporous AlSBA-15 silica, in the concentrations of 5, 10, 15 and 30 %, relative to the support. The textural properties and structural characterization of catalysts and supports were determined by techniques: X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) coupled to the chemical analyzer, adsorption / desorption of N2, thermal analysis (TG / DTG), absorption spectroscopy in the infrared (FTIR) and X-ray photoelectron spectroscopy (XPS). Characterization results indicated that the support AlSBA-15 retained the hexagonal ordered after the incorporation of zinc oxide and magnesium oxide in the holder. For heterogeneous catalysts, ZnO-AlSBA-15, that was observed the presence of zinc oxide nanoparticles dispersed in the surface and interior channels of the mesoporous and microporous support. The catalytic activity was evaluated by the transesterification reaction of sunflower oil via methylic route, and some reaction parameters were optimized with the most active catalyst in biodiesel production by sunflower oil. For the series of heterogeneous catalysts, the sample with 30 % ZnO supported on AlSBA-15 showed a better conversion of triglyceride to methyl esters, about 95.41 % of reaction conditions: temperature 175 °C, with molar ratio of 42:1, stirring at 200 rpm and under a pressure of 14 bar for 6 h. The catalyst MgO-AlSBA-15 showed no catalytic activity in the studied reactions

Serviço Social e Política: uma análise da participação dos assistentes sociais no Conselho Regional de Serviço Social 14ª região

This paper analyzes the political participation of Social Workers at the Social Service Regional Council Region 14th. The theoretical and methodological framework of this investigation has as its perspective the totality of social life and its determining relations within the object of study. To the production, analysis and collecting of data it was used a qualitative approach considering a bibliographical and documental research as well as a series of twelve interviews with 2005-2008 and 2008-2011 managing counselors of CRESS/RN. It was also used the data obtained from other special interviews held with the social workers in the period between 2007 and 2008. The results of this study allow and affirm the political dimension of Caseworkers and the CRESS/RN as a space of political activity with opportunities for effective and collective elaboration of strategies in order to reach the fulfillment of the ethical and professional policy of the Social Work. From a historical viewpoint, the beginning of this process is marked by the struggle for democracy, the end of military dictatorship, the establishment of the State of Human Rights. The Democratization of the so called Federal Council of Social Workers and its Regional Councils of Social Workers, CFAS / CRAS, respectively, area a result of the participation of the category in an effort to fight for democratization in Brazil. The objective of this research, so, is to understand which the socio-historical determinants are, that focus objectively and subjectively in the demobilization of social workers in CRESS Region 14th - in the contemporary and historical context. Among the results obtained we identified the ignorance of some professional workers and also of some advisors, regarding the existence and the role of the Council, as well as the commercialization of Education that compromises the quality of the professional training in its theoretical and methodological, ethical and political dimensions. According to our understanding, this shows a the presence of a non-critical professional profile based on a false reality, on the precariousness of employment contracts which undermine the political organization and submit the worker to various social exploring mechanisms such as double shift and ultimately the fragility of the management of the Regional Council -, as a consequence of the offensive capitalist system that ideologically invests to stop the political organization founded in a critical and democratic perspective. The low participation of some advisors and, in general, the category in CRESS / RN, despite its objective conditions, is a reality and it is presented to us as a challenge to future managements and policy consolidation to society. Inasmuch as the category intends to guarantee the high quality of its social workers, the demands of future counselors, their skills and abilities in dealing with regulatory issues, administrative policies that pervade the everyday life of CRESS / RN are necessary
