Citotoxicidade de cimentos retrobturados experimentais em fibroblastos V79: [recurso eletrônico]

Combining the characteristics of good adhesion and sealing of the AH Plus sealer the biological properties of the MTA, zinc oxide and calcium hydroxide, the purpose of this study was to evaluate the cytotoxicity of these associations. The specimens of the sealers and their associations were mixed and exposure to culture medium (82.4 mm2surface/mL) after the manipulation and incubated in a humidified incubator (37°C and 100% humidity) for 24 h. Chinese hamster lung fibroblasts (V79) were exposed to different dilutions of this extracts for 24 h and cell viability was measured by MTT test. The differences between the cell survival rates were statistically analyzed for Kruskal-Wallis and Dunn (p≤0.05). All sealers showed a significant difference with the group control, except the MTA. Cytotoxicity with the control group increased in the following order: AH Plus < AH Plus + Ca(OH) 2 < AH Plus + OxZn< AH Plus + MTA < MTA (p≤ 0,05). It was concluded that the addition of biological materials in order to improve the consistency of AH Plus for use in retro cavities its toxicity has not decreased significantly

Estudo do potencial de associações de ZnO com os produtos naturais ácido cafeico e ferúlico como filtros solares híbridos: [recurso eletrônico]

In this work were studied associations of ZnO with the natural products caffeic and feluric acids. Two preparation methods were used, that is, the sol-gel and a reflux procedure. In the sol-gel method, ZnO is produced by the basics hydrolysis of precursors in the presence of the organic filters (caffeic and feluric acids), which results in 30 nm (or less) ZnO particles with the organic filters (in dissociated form) bonded to the surface of ZnO. In the reflux method, a dispersion of ZnO in a water/ethanol mixture was kept under reflux (50oC/4h) in the presence of the organic acids. The ZnO particles used in the reflux method have a higher diameter than sol-gel ZnO particles, but the prepared associated product ZnO/Organic acids were similar. Despite of the difference in relation to crystallinity between the products, the preparation methods resulted in analogous associations with respect to the interaction of the organic filters with the ZnO surface. The caffeic/ZnO associations presented low photostability, which lead to the degradation of the organic filter. The other associations (feluric acid/ZnO) presented satisfactory results. The FT-IR spectroscopy confirmed the formation of the association, and the nature of the bond formed compared with the Zn-O bond in Zn2+/Felutic acid complexes. The isolated organic and inorganic filters, along with the associations were analyzed by diffuse reflectance spectroscopy and Uv-vis spectroscopy. The absorption edges and the critical wavelengths were analyzed and the effects of Zn-O bonds in feluric acid/ZnO associations described as a function of the relative position of the π/π* system of the organic filter. Finally the performance of the hybrid filters were investigated in terms of the absorption of UVA and UVB radiations, with the UVA/UVB ratio, an efficiency parameter largely used in the description of solar filters, sunscreen and suncare products

Biodegradação da vinhaça resíduo da produção de etanol

The State of São Paulo is responsible for the largest sugar cane production in Brazil, as well as the largest production of ethanol made of this raw material – which is widely used as fuel for automobiles. This utilization began in the 1970’s, with the institution by the Brazilian government of the National Alcohol Program (PRO-ÁLCOOL), as a consequence of the petroleum crisis, rising again five years ago, with the development of flex fuel cars. The obtaining process of ethanol originates residues; amongst them, vinasse is the one that’s generated in the largest amount (an average of 10 to 13 litres/litre of ethanol produced). The disposal of this residue in waters was only forbidden in 1978, but before that, researchers had already been investigating its utilization as raw material. This paper had the objective of accompany the biodegradation of vinasse by evaluating the oxygen comsumption during it until the ultimate Biochemical Oxygen Demand (uBOD), performed in twenty days; another objective was to analyse the biomass production of Saccharomyces cerevisae in this residue. Physical and chemical analyses of the residue were also performed, as well as acute toxicity essays using Daphnia similis and Dugesia tigrina, before and after its biodegradation. The physical and chemical analyses pointed elevated acidness (pH = 3,98), conductivity (8,30 mS/cm) and COD (25.693,43 mg O2/L) and mean quantity of suspended solids (5.246 mg/L). The toxicity essays indicated absence of toxic potential in vinasse after biodegradation for both species. The uBOD degradated until 88,22% of the COD, demonstrating the possibility of biodegradation of most of the residue’s organic load in a relatively short period of time. S. cerevisae caused a 37,03% COD diminution in vinasse, diminished its conductivity and promoted a slight elevation of the pH; it obtained low biomass...(Complete abstract click electronic access below)

Articulação entre as políticas internas e externas no Brasil dos anos de 1980 aos nossos dias: uma análise valorativa sobre o desenvolvimento social e política-cultural

Assim como, as vivências nos intercâmbios internacionais podem e devem contribuir em grau elevado na constituição das mesmas políticas públicas, angariando recursos e investimentos externos, elas também podem se aprofundar em experiência de conscientização dos sujeitos políticos. Quanto mais a difusão cultural entre os povos é incentivada, pelos governos e iniciativas não governamentais, somada à atividade política dos sujeitos, mais trará contribuições aos entremeios das sociedades complexas, que por sua vez, refletirão na melhoria das condições de vida dos indivíduos e de suas instituições. O plano discursivo ideal propõe a superação das amarras econômicas para contemplar os estratos sociais, essa seria a primeira etapa para iniciar o aperfeiçoamento das instâncias democráticas e, convém assistir às transformações desde as estrutura, ou seja, dos modos de pensar, ser e agir dos seres humanos em busca de um novo tipo de desenvolvimento, que de fato se reconheça globalizado. Para tanto, o método utilizado se ancorou na revisão bibliográfica da análise histórica e da análise de discursos dos ex-presidentes, a partir da época de redemocratização brasileira. A todo o momento, frisou-se a articulação entre as mais diversas frentes de organização social, interna e externa, bem como as supranacionais, tal articulação é oportuna à metodologia, na tentativa de uma compreensão introdutória dos processos da modernidade complexa. Além disso, optou-se por tecer considerações finais que deixassem o texto aberto ao debate, ao contrário de qualquer proposta conclusiva. A saber, a potencialidade em dialogar sobre o conceito de desenvolvimento, que se deseja pluralmente inserido na universalidade relativa ao gênero humano, torna-se mais atraente, à medida que são cobradas melhorias dos programas político-democráticos...

Contribuições do PIBID para a formação inicial de professores: um olhar dos licenciandos em física da Faculdade de Engenharia de Guaratinguetá

The current work aims to analyze the contributions of PIBID for initial graduation of the teachers, in view of the undergraduates of Physics Course at UNESP Guaratinguetá . A brief literature survey about the national situation of teacher education was performed, at which the main difficulties and challenges, as well as the solutions stated in place by the government to solve them, have been highlighted. A description of the historical of PIBID at UNESP, from the institutional project to reach the subproject developed by Physics Course of Guaratinguetá, was presented. To characterize the development of the subproject, it was performed a survey on the activities performed by the PIBID’s scholars, since its implementation on campus in 2010 until the end of the year 2013, in order to map the experiences lived by program participants. These data were obtained from the analysis of reports by scholars themselves, video analyzes and record of the weekly meetings held by the group, reading electronic messages exchanged on a specific group of e-mails and written evaluations by members of the program. Completing data collection, eleven scholars undergraduates of the program were interviewed, and the results were classified by topics, defined from recurrence in the interviewees speech. The global analysis of the data was based on theoretical references commonly used in research on graduation of teachers, as Nóvoa (1992), Mizukami (2005, 2006) and Gatti (2008). The results indicate that the licensed ones see in PIBID a differentiated opportunity for initial teaching graduation, for adding practical learning experiences for students of EB within the school context, and especially for creating space for reflection on their experiences with the support of more experienced teachers, committed to the training of all involved ones

Um contexto histórico e sócio-ambiental dos povos da floresta do Acre: ensaio sobre história recente desses povos e as políticas públicas estaduais do Governo da Floresta

O Estado do Acre, território mais recentemente incorporado ao Brasil, até meados do século XIX apresentava em seu território apenas povos tribais ameríndios, que lá habitavam desde milênios. O histórico de povoamento mais recente do estado (a partir da segunda metade do século XIX) está atrelado com o mercado internacional da borracha, a região foi o destino de milhares de pessoas em busca de fazer a vida explorando as seringueiras. A partir de então uma série de disputas fundiárias ocorreram na região, o que foi um dos fatores que influenciaram na conformação da sociedade acreana. O movimento ambientalista surgiu no estado como resultado dessas disputas fundiárias na segunda metade do século XX. No final da década 90 o governo estadual, assimilando o discurso ambientalista, assume o governo com a Frente Popular do Acre, composta por uma série de partidos, com o autodenominado “Governo da Floresta” e usando o neologismo “florestania” como símbolo do projeto do governo. Apesar de utilizar amplamente em seu discurso temáticas ambientais e dos povos da floresta, acabou ao longo dos anos tendo atitudes com um cunho mais doutrinador do que emancipador. A discrepância entre a prática e o discurso do “Governo da Floresta” é então analisada a partir de conceitos como “Ecologia dos Saberes” e “Biopoder”, conceitos que auxiliam na identificação das atitudes de cunho doutrinador postas em prática pelo governo. Considerando como “ecologia dos saberes” aquela forma de conhecimento que tem a premissa um reconhecimento da pluralidade de conhecimentos heterogêneos que em interações sustentáveis e dinâmicas entre eles não comprometem suas autonomias e “biopoder” como aquela forma de poder que exerce a sua dominação sobre a própria vida da população, estabelecendo como é que esses devem viver

Nos últimos 40 anos, a biotecnologia tem evoluído significativamente, gerando uma série de repercussões e possibilidades para diversos setores. Embora os avanços tenham impactos muito amplos, um dos setores que mais se beneficiam do desenvolvimento da biotecnologia é a agricultura. Em meio a um contexto favorável para o desenvolvimento da biotecnologia no Brasil, buscaremos analisar o papel do setor público, de instituições de pesquisa e ensino e de empresas nacionais e transnacionais, bem como o estímulo à cooperação entre universidades e empresas do setor de defensivos agrícolas e sementes

Avaliação in vitro da ação de substâncias químicas auxiliares, clorexidina e medicações intracanais sobre C. albicans, E. faecalis, E. coli e sua endotoxina em canais radiculares: [recurso eletrônico]

The purpose of this study was to evaluate the antimicrobial activity of chlorhexidine gel 2% as auxiliary chemical substance on the biomechanical preparation (BMP) and medication intracanal (ICM) on C. albicans, E. faecalis, E. coli and their endotoxin in root canals. We used 48 single-rooted human teeth divided into four groups according to dressing ICM: 1) Ca(OH)2 + pyrogen-free saline solution; 2) 2% chlorhexidine gel (CLX); 3) Ca(OH)2 + CLX, and; 4) pyrogen-free saline solution (control group). Were collected the contents of root canals to confirm the presence of microorganisms (confirmation), immediately after instrumentation (1st collection), after 7 days of the BMP (2nd collection), after 14 days of the action of ICM (3rd Collection) and 7 days after removal of the ICM (4 th collection). Were performed: the evaluation of antimicrobial activity and the content analysis of endotoxins for all sampling tests. The results were statistically analyzed using Kruskall-Wallis and Dunn tests with a significance of 5%. It was found that the CLX as auxiliary chemical substance has significantly reduced microorganisms confirmation collection when compared. In relation to the neutralization of endotoxin, it was found that the 1st and 2nd collections presented a decrease of 92.03% and 98.10% in mean percentage respectively, when compared to the confirmation collection. In the 3rd and 4th samplings, the Ca (OH)2 + CLX group showed the best results. It was concluded that the BMP and the ICM were able to eliminate the tested microrganisms, however, they were not able to completely eliminate endotoxins root canal

Planejamento ambiental do distrito de Ameliópolis – Presidente Prudente - SP

The concern with the environmental planning has become important in Brazil recently. Until then, nature was conceived as a resource, because of the implementation of developmental policies that perdured to the 1970s, based on the expansion of the industrial complex, altogether hadn´t preoccupation by the federal government with the relationship between society and nature. During this period, after the threat of not receiving more international investment to finance large projects in the country, accompanied by pressure from civil society organizations, the federal government began to take some action related to the environment, such as the creation of federal agencies (IBAMA), application of environmental laws and decrees in order to create rules for the proper use of natural resources such as water, soil and air. From the decade of 1990 onwards the master plans have become a mandatory document for all municipalities in the country with a population over 20,000 inhabitants, ranging from health issues to the development of urban, rural and environmental planning. Thus, the environmental planning gained prominence in the political scene. Therefore, to achieve environmental planning is necessary to follow some social and environmental parameters, which for this survey, conducted in the District of Ameliópolis – Presidente Prudente...

Estudo das políticas de obtenção dos assentamentos de reforma agrária no Brasil entre 1985 e 2009

Understanding the territorial transformations is important to the geographic knowledge, especially when it is related to structural questions as agrarian one. In this way, the land acquisition to agrarian reform enables us to understand some of these transformations, represented by territorialization of landless workers in rural settlements, that are concrete results of the struggle for land that boost the policies of agrarian reform in our country. The renewal of the agrarian structure is fundamental to the concept of land reform and also provides that advances social, political, cultural, economic, etc. Classified as a country with rates of the highest land concentration in the world, Brazilian government attempts to base his actions to take in the expropriation of land the main character of the land reform. However, new policies have been gradually used to obtaining the rural settlements, in a process that Fernandes (2010) called the reconceptualization of land reform. Starting in 1985, Brazil has 63% of the beneficiaries of land reform policies settled on expropriated land, the rest is a result of incorporation policies such as land regularization, of land reform and land purchase. Such policies generate changes in agrarian structure, that is the goal of land reform, but don´t concentrate to the land ownership. This attitude of the state in coping with the agrarian question is his response to the pressures of capitalist agriculture represented by landowners and agribusiness, coping catching an intense and uneven territorial dispute with peasant agriculture, in an attempt to impose its model of development for the field. The aimed of this present study is to understand better the land reform acquisition and its implications in the Brazilian territory, in order to understand it in their multiplicity.
