CFD Applied to Process Development in the Oil and Gas Industry – A Review
Computational Fluid Dynamics (CFD) is increasingly used in the oil and gas industry. The present article aims to show how CFD can be used at all steps of the development of a new process, with a focus on refining technologies. Those different steps consist first of setting up tools that will be used during the development phase, second of obtaining data in complement with experiments required for the process development, and finally, of troubleshooting actions or technology developments that will make the process even more efficient. A large number of applications corresponding to various flow configurations, single-phase or gas-liquid, gas-solid or even gas-liquid-solid, characterised by significantly different scales and requiring adapted simulation approaches, are discussed based on original results and a review of the literature. Perspectives are given in particular on the multi-scale approach and physical phenomena coupling
Prevalência de maloclusão e sua associação com alterações funcionais do sistema estomatognático entre escolares Prevalence of malocclusion and its association with functional alterations of the stomatognathic system in schoolchildren
Esta pesquisa objetivou estimar a prevalĂŞncia de maloclusões entre escolares com 12 anos de idade do MunicĂpio de Camaragibe, Pernambuco, Brasil. As maloclusões foram estratificadas em função do grau de severidade, analisando-se, ainda, a sua associação com as alterações das seguintes funções: fonoarticulação, respiração e deglutição. A oclusĂŁo foi avaliada por intermĂ©dio do Treatment Priotiy Index (TPI) e as referidas funções por meio de critĂ©rios utilizados na rotina clĂnica fonoaudiolĂłgica por um Ăşnico examinador calibrado (valores de kappa variáveis entre 0,64 e 1,00). Os escolares foram selecionados randomicamente em 11 escolas pĂşblicas. Dos 173 sorteados, 82,1% apresentaram maloclusĂŁo (IC95%: 76,4-87,8), sendo 38,2% consideradas manifestações menores de maloclusões; 20,8% maloclusões definidas; 13,3% maloclusões severas; e 9,8% maloclusões muito severas. Conclui-se que há uma alta demanda reprimida por tratamentos ortodĂ´nticos e que quanto maior a severidade das maloclusões maior Ă© a possibilidade de associação com alterações funcionais, fato que deve ser levado em consideração no planejamento de serviços pĂşblicos destinados aos referidos agravos.<br>The aim of this research was to estimate the prevalence of malocclusion among 12-year-old schoolchildren in Camaragibe, Pernambuco State, Brazil. Malocclusions were stratified by the degree of severity, and their association with alterations of the following functions was also analyzed: speech articulation, respiration, and deglutition. Occlusion was assessed by means of the Treatment Priority Index (TPI) and the functions referred to by means of the criteria used in routine clinical speech therapy by a single calibrated examiner (kappa values ranging from 0.64 to 1.00). Schoolchildren were selected randomly from 11 public schools. Of the 173 selected children, 82.1% presented malocclusion (95%CI: 76.4-87.8), with 38.2% classified as minor manifestations of malocclusion; 20.8% definite malocclusions; 13.3% severe malocclusions; and 9.8% very severe malocclusions. The conclusion was that there is a high repressed demand for orthodontic treatment, and that the greater the severity of the malocclusion, the stronger the possibility of association with functional alterations, which must be taken into consideration when planning appropriate public services for these conditions

Make EU trade with Brazil sustainable
Brazil, home to one of the planet's last great forests, is currently in trade negotiations with its second largest trading partner, the European Union (EU). We urge the EU to seize this critical opportunity to ensure that Brazil protects human rights and the environment
