Fatores associados à quantidade e tipos de gordura disponível para consumo, presentes nos alimentos industrializados adquiridos pelas famílias paulistanas

Este trabalho examina o papel dos alimentos industrializados no acesso às gorduras. Ele analisa os determinantes socioeconâmicos da quantidade e do tipo de gordura disponível para consumo pelas famílias paulistanas, presentes nos alimentos industrializados. Essa análise envolveu uma amostra de 576 famílias no município de São Paulo, cujos dados foram coletados no período de 2008 a dezembro de 20 10, selecionada após alguns critérios excludentes. A fonte dos dados é a Pesquisa de Orçamentos Familiares da FIPE, que está em andamento desde 2008, atualizada através da ponderação do Índice de Custo de Vida da FIPE. Baseado em métodos analíticos de estatística descritiva (média, desvio-padrão, mediana), testes t de student, e métodos econométricos de regressão múltipla, alguns resultados foram encontrados. Os fatores associados aos gastos com alimentos industrializados foram renda, tamanho da família, idade e grau de instrução do chefe. Em relação à gordura total identificou-se como fatores associados renda, tamanho da família, idade do chefe, a presença de crianças na família e a proporção do gasto com alimentação com derivados de leite e derivados de carne.

Compactação e elevação da vida útil de transformadores de distribuição empregando óleo vegetal isolante.

A busca no aumento da vida útil dos transformadores de distribuição, redução dos custos de manutenção e mitigação de falhas, leva ao desenvolvimento de novos materiais e critérios de exploração diferenciados desses ativos. Esta pesquisa apresenta o desenvolvimento de um novo transformador de distribuição compacto e mais eficiente utilizando óleo vegetal isolante totalmente biodegradável. Além de biodegradável, o óleo vegetal utilizado possui menor agressividade ambiental e maior capacidade térmica aumentando, a capacidade de carregamento do transformador sem comprometer a sua vida útil. A fim de atestar essa menor agressividade em relação ao óleo mineral, ensaios foram efetuados em um equipamento que permaneceu 12 anos em operação. O equipamento foi totalmente desmontado para análise e coleta de amostras de papel e óleo vegetal isolante. As análises visam comprovar a menor agressividade em relação ao óleo mineral, apresentadas na revisão bibliográfica. A menor agressividade torna possível a proposição de uma nova filosofia de planejamento de redes de distribuição utilizando uma quantidade menor dos novos transformadores para uma mesma carga, tornando-a mais compacta e eficiente.

RAZÃO E MÍSTICA. ALGUMAS CONSIDERAÇÕES A PARTIR DO PROSLOGION DE SANTO ANSELMO

Numa revisitação do Proslogion anselmiano, busca-se tentar descodificar a sua complexidade em função das duas vertentes razão e mística, positividade e negatividade. Inserindo-se o texto numa linha de interioridade nítida, nele ressalta o significado da formulação do célebre argumento, encontrada a esse nível, para tentar expressar Deus e demonstrar lógica e rigorosamente, em toda a plenitude da razão, a sua necessária existência, como caso único e excepcional: aliquid quo nihil maius cogitare possit. Pode afirmar-se que o raciocínio no seu encadeamento racional se estrutura sem falhas, afastando qualquer confusão entre o nível do conceptual e do real, chegando a uma conclusão necessária e irrefutável, se se aceitarem os mesmos pontos de partida. A utilização dos termos aliquid e id impede que essa formulação possa ser considerada como definição ou conceito, fechados em si mesmos, tal como a sua expressão de negatividade, na sua indeterminação, desvela uma necessidade urgente e contínua do racional se ultrapassar a si mesmo, num caminho de algo apenas pressentido. Esta perspectiva, que se conexiona em última análise com a perspectiva dupla da própria Revelação como desocultação/ocultação, projecta-se no próprio texto, o qual como que se cinde a partir do capítulo XIII, na análise dos atributos de Deus, deixando de lado uma via de positividade que se esgota e abrindo-se à negatividade. Se a ratio pode argumentar, concluir e chegar à descoberta de um argumento estruturado e coerente, com amplitude universal, apercebe-se, igualmente, das suas limitações. O alargamento máximo das capacidades da razão para chegar a Deus, não basta a Anselmo, já que experiencia, paralelamente, o seu desespero em não conseguir ver a Sua face. É essa tensão subjacente a todo o texto do Proslogion e mais claro ainda nos últimos capítulos, que desvela a dialéctica da razão e da mística, interagindo, sem que se misturem os seus processos, os seus métodos e as suas linguagens, desencadeando, afinal, uma busca sempre inconclusa do Absoluto. Este dinamismo processual de forças em presença que, mergulhando as suas raízes nos Platonismos clássicos transmutados pela Patrística, virá a aflorar, claramente, na mística especulativa do século XII, marca fundamente o pensamento medieval. Com efeito, nele estão sempre presentes, um entendimento lúcido da razão e a confiança nas suas capacidades especulativas, e, paralelamente, o reconhecimento claro da sua relatividade e o apelo de uma Presença pressentida mais do que pensada. Assim a razão é impedida de se fechar em círculo, já que tenta, sempre, chegar ao Absoluto que não a determina, mas que a motiva incessantemente, para além do humano.

Aplicação de agentes remineralizantes sobre o esmalte clareado: eficácia contra o manchamento por café

The aim of this study was to evaluate the influence of remineralizing agents on the susceptibility of enamel cleared by the coffee pigmentation during office bleaching. Fifty bovine incisors were selected and randomly assigned into 5 groups (n = 10) on the basis of remineralizing agents: G1 gel hydrogen peroxide to 35% (control group); G2, hydrogen peroxide gel and a 35% gel 2% neutral fluorine; G3, hydrogen peroxide gel and a 35% nanostructured calcium phosphate gel, G4, hydrogen peroxide gel and a 35% casein fosfoptídia-phosphate and amorphous calcium folder; G5 hydrogen peroxide gel to 35% without mineralizing agent. All groups exception G1 (control group) were subjected to pigmentation soluble coffee according to the manufacturer's guidelines. The samples were immersed in coffee at temperature of 55° C, 1 time a day for 4 minutes. Color changes were performed by Easyshade spectrophotometer at CIE Lab method before and after 3 whitening sessions. Data were analyzed by analysis of variance ANOVA. The results showed statistically significant differences between the remineralizing substances for the parameters L *, a *, b * ΔE (p <0.0001). The L * values for the group G5, and the b * for G2 and G5 groups differed from the control group. After the 3rd whitening session, Fluor's group (G2) and that without mineralizing agent (G5) showed ΔE values less than the control group that did not undergo pigmentation. It was concluded that only the nanoclusters remineralizing agents Phosphopeptides Casein-Amorphous Calcium Phosphate and Calcium Amorphous phosphate were able to reduce the coffee interference whitening efficacy of hydrogen peroxide.

Os impactos na qualidade da água e do solo de um manancial tropical do semiárido devido ao uso e ocupação e evento de seca extrema

Human activities alter soil features, causing the deterioration of its quality. Land use and occupation in drainage basins of water supply reservoirs can change the environmental soil quality and, thus, lead to the expansion of the soil potential of being a diffuse pollution source. In the Brazilian semiarid region, the soils are generally shallow with high susceptibility to erosion, favoring the sediment and nutrients input into the superficial waterbodies, contributing to the eutrophication process. Moreover, this region has high temperatures and high evapotranspiration rates, that are generally higher than the precipitation rates, causing a negative hydric balance and big volume losses by evaporation. The water volume reduction increases the nutrients’ concentration and, therefore, exacerbates the eutrophication process, deteriorating the water quality. Thereby, we hypothesized that the eutrophication process of semiarid reservoirs is intensified both by the extreme climatic events of prolonged drought, and by the diffuse pollution due to the basin land use and occupation. The study aimed to test whether the land use and occupation activities of the basin and the severe drought events intensify the eutrophication process of a semiarid tropical reservoir. To verify the influence of human activities carried out in the water supply of drainage basin on the soil quality and the eutrophication process, we conducted the mapping of the kind of use and occupation, as well the calculation of erosion for each activity and the soil quality evaluation of the riparian zone and water quality of the water supply. For the water analyses, the samplings were carried out monthly in the deeper point, near dam. For the soil, deformed composite samples were taken for the physical and chemical attributes analysis, according to the identified land use and occupation classes. The results showed that extreme droughts drastically reduces the water volume and elevates the nutrients concentration, contributing, thus, to a bigger degradation of water quality. Furthermore, we verified that human activities in the drainage basin promote the diffuse pollution, by increasing the soil susceptibility to erosion and nutrients contents. Summarizing, our results support the investigated hypothesis that activities of land use and occupation and extreme drought generate a combined effect that provide the intensification of eutrophication process of semiarid reservoirs.

Relações entre mecanismos de coordenação e controle com desempenho organizacional: um estudo nas instituições públicas de ensino médio de Natal

This research aimed at relating coordination and control forms to organizational performance. The multicase study was applied in two public high schools: Centro Federal de Educação Tecnológica do Rio Grande do Norte and Floriano Cavalcanti. In order to accomplish these objectives, it was developed a qualitative analysis and considered coordination and control forms of several authors. Also was considered Sander´s (1984) model of organizational performance. The mentioned model considers two criteria to analyze organizational performance: one instrumental (efficiency and efficacy) and other substantive (effectiveness e relevance). The research attempts to show the importance of balancing these criteria in a way that effectiveness and relevance becomes more important at schools. It was proven that the use of bureaucratic coordination forms has the power to influence the evaluation on the instrumental technique. At the same time, it was observed that the use of mechanisms based on the autonomy of the school is related to efficiency and efficacy. The object of this research can be considered successful

Promoting oral health in adults with learning disability

Introduction: It is complex to define learning disabilities, there is no single universal definition used; there are different interpretations and definitions used for learning disabilities in different countries and communities. Primarily, the term “learning disability” sometimes used as “learning difficulties” is a term widely used in UK. There are various types and degree of severity of learning disabilities depending upon the extent of disorder. Though different definitions used all over the world, its types and classification coupled with their health and oral health needs are discussed in this review. Objectives:  To review the background literature on definitions of learning disabilities and health needs of this population.  To review literature on individual clinical preventive intervention to determine the effectiveness in promoting oral health amongst adults in learning disabilities.  To review literature in relation to community based preventive dental measures.  To determine the interventions in this areas are appropriate to support policy and practice and if these interventions establish good evidence to suggest that the oral health needs of adults with learning disabilities are met or not.  To make recommendations in implementing future preventive oral health interventions for adults with learning disabilities. Methodology: It was develop a comprehensive narrative synthesis of previously published literature from different sources and summarizes the whole research in a particular area identifying gap of knowledge. It provides a broad perspective of a subject and supports continuing education. It also is directed to inform policy and further research. It is a qualitative type of research with a broad question and critical analysis of literature published in books, article and journals. The research question evaluated on PICOS criteria is: Effectiveness of preventive dental interventions in adults with learning disabilities. The research question clearly defines the PICOS i.e. participants, interventions, comparison, outcome and study design. The Cochrane database of systematic reviews (CDSR), Database of Abstracts of Reviews of effects (DARE) through York University and National institute of Health and Clinical Excellence (NICE) was searched to identify need of this review. There was no literature review found on the preventive dental interventions found hence, justifying this review. The guidance used in this review is from York University and methods opted for search of literature is based on the following: Type of participants, interventions, outcome measure, studies and search. The review of literature; author search; systematic and narrative reviews, through the following electronic databases via UFP library services: Pub-Med, Medline, EMBASE, CINHAL, Google scholar; Science Direct; Social and Medicine. A comprehensive search of all available literature from 1990-2015, including systematic reviews, policy documents and some guideline documents was done. Internet resource used to access; Department of Health, World Health Organization, Disability World, Disability Rights Commission, the Stationery office, MENCAP, Australian Learning Disability Association. The literature search was carried out with single word, combined words and phrases, authors' names and the title of literature search. Results: It is primarily looking at the oral health interventions available for adults with learning disabilities in clinical settings and the community measures observed over a period of 25 years 1990-2015. There were 7of the clinical intervention studies and one community based intervention study was added in this review. Conclusion: There is a gap of knowledge identified in not having ample research in the area of preventive dental interventions in adults with learning or intellectual disabilities and there is a need of more research, studies need to be of a better quality and a special consideration is required in the community settings where maintenance of oral hygiene for this vulnerable group of society is hugely dependent on their caregivers. Though, the policy and guideline directs on the preventive dental interventions of adults with LD there still a gap evident in understanding and implication of the guidance in practice by the dental and care support team. Understanding learning disabilities and to identify their behavior, compliance and oral health needs is paramount for all professionals working with or for them at each level.

Análise de modelos geológicos utilizando percolação dinâmica

In the present study we elaborated algorithms by using concepts from percolation theory which analyze the connectivity conditions in geological models of petroleum reservoirs. From the petrophysical parameters such as permeability, porosity, transmittivity and others, which may be generated by any statistical process, it is possible to determine the portion of the model with more connected cells, what the interconnected wells are, and the critical path between injector and source wells. This allows to classify the reservoir according to the modeled petrophysical parameters. This also make it possible to determine the percentage of the reservoir to which each well is connected. Generally, the connected regions and the respective minima and/or maxima in the occurrence of the petrophysical parameters studied constitute a good manner to characterize a reservoir volumetrically. Therefore, the algorithms allow to optimize the positioning of wells, offering a preview of the general conditions of the given model s connectivity. The intent is not to evaluate geological models, but to show how to interpret the deposits, how their petrophysical characteristics are spatially distributed, and how the connections between the several parts of the system are resolved, showing their critical paths and backbones. The execution of these algorithms allows us to know the properties of the model s connectivity before the work on reservoir flux simulation is started
