Uma das principais causas de poluição da água está na extração de minerais e combustíveis fósseis do solo ou até mesmo de oceanos. A busca intensa por esses recursos naturais para criação de produtos derivados cresce em larga escala, aumentando, consequentemente, a sua exploração. Entretanto, o seu vazamento na natureza pode causar sérios problemas à vida dos humanos e animais. Neste contexto, o presente trabalho apresenta um estudo dos autômatos celulares e suas aplicações, e propõe um modelo para realizar simulações de espalhamento de fluidos, e posteriormente apresenta um protótipo do sistema para suportar essas simulações. Experimentos e testes foram realizados para analisar como as variáveis envolvidas afetam o espalhamento de fluidos dentro do ambiente simulado.
Interactive learning on the Web may be a way to partially supplement the classroom learning ex-perience by providing an interactive environment similar to the classroom but with more attentionto individual student needs. New computational resources are available every day, and these newtechnologies that help the understanding process can be popularized by free full access web sites, asBiochemical View. This site, available at http://www.unb.br/cbsp/bioq, was developed at Universityof Braslia (UnB) to support Biochemistry classes of this and any other Universities, since its alsoavailable in an English version. The contents - that include the usual metabolic pathways referentto the metabolism of carbohydrates, amino acids, lipids and nucleic acids - are presented in bi andthree-dimensional formats, easily accessible and assimilable, complemented with objective texts anddescription of regulation points. Protocols for experimental classes, reference materials, and specicinformation about each molecule of all pathways are also available, including metabolic participationschemes of them. An evaluation form of the site is available on-line, developed using PHP. Besidesthe positives results, the suggestions collected in these evaluations since 2001 have been guiding theactualizations. So, the site is the result of students opinions and needs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
