Living organisms are constantly subjected to the action of free radicals, which are one of the causes of oxidation reactions, because they have on free electron, what makes it very reactive. They are products of organism reactions or they are produced by exogenous factors, such as tobacco. Fatty acids are the most vulnerable target, and may suffer lipid peroxidation, what affects the cell structure. Cardiovascular diseases, cancer and diseases of aging are occurrence of these reactions in the organism related. The aliments are also subjected to suffer oxidation reactions, what make them unfit for consumption and decreasing the useful life. Synthetics antioxidants are used as aliments preservatives, but they present some toxicity for the organism. Studies for the utilization of natural antioxidants have gained more importance in recent decades, due to the conservation potential and low toxicity. Phenolics compounds are largely present at the vegetable kingdom and they present high antioxidant potential due to the neutralization and kidnapping of free radicals capacity. These compounds are used by the industry at the aliments conservation, specially the phenolics acids. The consumption of aliments rich in phenolic compounds, such as teas, wines and fruits are low incidence of degenerative diseases related. This study consists in a bibliographic revision that covers these compounds importance in diet and at the food conservation, and the methodologies and difficulties in the extraction process due to variety of molecules of this group.

O Direito de propriedade, seguindo o desenvolvimento da sociedade, evoluiu e suportou grandes transformações ao longo da história. Diversas foram as concepções que surgiram para explicar sua natureza, partindo da idéia exposta no regime feudal, onde somente ao senhor cabia o direito de propriedade, passando para um conceito que consagrou a propriedade como um direito sagrado e inviolável, até acolher expressa e constitucionalmente sua função social, na consagração máxima ao princípio da Soacialidade, reflexo da publicização do Direito Civil moderno. Mesmo nos dias atuais, trata-se de um assunto emblemático haja vista sua utilização tímida na administração publica, muito embora o princípio da função social da propriedade tenha sido genericamente consagrado na Constituição Federal de 1988, igualmente adotado pelo Código Civil de 2002. O presente artigo, de caráter multidisciplinar, composto de duas fases, se propõe a analisar, inicialmente, a (in)aplicabilidade da função social dos bens públicos dominicais, estudo que se situa em uma zona cinzenta entre o Direito Constitucional, o Direito Administrativo e o Direito Civil. Para tanto, será feito uso dos princípios de interpretação constitucional, a fim de se alcançar o real sentido da norma estatuída nos artigos 170, III, 182 e 186, da Carta Política de 1988, além dos artigos 421, 1228, 1239 e 1240, das normas de direito material, e da análise do Estatuto das Cidades, inovação constitucional que delega aos Municípios a competência para impor a desapropriação, como decorrência última das sanções suportadas pelo proprietário, em razão do uso degenerado da propriedade urbana. Portanto, ainda que a aplicação da função social aos patrimônios públicos nos parece redundante, já que compete ao Estado a garantia do bem comum, resulta necessário, no panorama atual, fixar os parâmetros para a construção de um novo modelo de gestão do patrimônio público, atribuindo uma destinação adequada aos bens dominicais ociosos, que atenda a função social e atenda aos interesses públicos, em detrimento dos interesses dos rent seeking, tema abordado na segunda fase de desenvolvimento do presente projeto, conforme se poderá verificar com as conclusões apresentadas, haja vista que a tese apresentada busca revolucionar os modelos atuais de gestão do patrimônio público, que permanece mais público do que nunca, apenas com critérios bem definidos e estabelecidos para sua destinação, que em sendo adequada favorecerá o desenvolvimento econômico, social e cultural da sociedade, reduzindo as desigualdades.

This article discusses the Brazilian land problem related to property rights of rural land. After emphasizing the importance of land policies in order to define and distribute rural land properties rights, we show how in Brazil the institutions of rural land registering and cadastering as separated processes debilitates the property rights, making them vulnerable to the effective occupying actions. In order to illustrate it, in this article we analyze Data based in a Case Study of conflict and property rights distributions in an important farming and mining region of southern Para state, in Brazil.

Hypomineralized first molar often in combination with hypomineralized incisors (MIH - molar incisor hypomineralization) is a common finding in everyday practice. In this condition, hypomineralized dental enamel is fragile and soft, and it can break easily leading to an exposed dentin, and causing dental sensitivity and progression of caries lesions. The prevalence of MIH range from 3.6 to 25% in North of Europe that consider this condition a public health problem. No conclusive information was reported about the etiologic factors of MIH, however, systemic causes seem to be of importance. Several aetiological factors are mentioned as the cause of this condition and they are frequently associated with complications during pregnancy and childhood diseases during the first three years of life. MIH is frequently misinterpreted as fluorosis, hypoplasia or amelogénesis imperfect, however, this condition presents defined clinical aspects that can distinct it from the other defects.

Objectives: The objective of this study was to evaluate the ability of endodontists and general practioners to perform the differential radiographic diagnosis between internal and external root resorptions, using digitized periapical radiographs. Methods: Thirty periapical radiographic images of external and internal resorption were selected. The evaluators were comprised of 15 endodontists and 29 general practitioners who answered a questionnaire with the following question: “What type of resorption in the following radiographics do you diagnose?” (1) Inflammatory external root resorption. (2) Internal root resorption. Statistical analysis was performed based on the Mann-Whitney test, with significance level of 5%. Results: There was no statistically significant difference in the percentage of correct answers from specialists in endodontics and general practitioners. Conclusions: Both groups demonstrated satisfactory skill in the radiographic interpretation of internal and external resorption and there was a higher percentage of correct diagnosis of internal resorption than the external.

Since the decade of 1990's, a debate has grown about the so called creative industries. The creatives industries are build for sectors where the creativity emerges as a main input for the products elaboration which are valued by intellectual property statutes. The present monograph intends to describe Journalism as a creative activity, expose how intellectual property works in this area and analyze the function of news aggregators, like Google News, both in author rights matter terms, as about on the recent news mediator and distributor role on digital platforms

We investigate in this work the behaviour of the decay to the fixed points, in particular along the bifurcations, for a family of one-dimensional logistic-like discrete mappings. We start with the logistic map focusing in the transcritical bifurcation. Next we investigate the convergence to the stationary state at the cubic map. At the end we generalise the procedure for a mapping of the logistic-like type. Near the fixed point, the dynamical variable varies slowly. This property allows us to approximate/rewrite the equation of differences, hence natural from discrete mappings, into an ordinary differential equation. We then solve such equation which furnishes the evolution towards the stationary state. Our numerical simulations confirm the theoretical results validating the above mentioned approximation
