13. Retenção do dimetoato e sua relação com pH e teores de argila e matéria orgânica nos sedimentos da zona não-saturada de uma microbacia no nordeste paraense
Na agricultura familiar na Amazônia oriental, em particular no nordeste do Pará, são comuns os cultivos semi-perenes com pesada aplicação de agrotóxicos. Em virtude da ampla utilização desses produtos, principalmente o dimetoato, na microbacia hidrográfica do igarapé Cumaru, município de Igarapé-Açu (PA), foi avaliada a retenção dessa substân

18. Poluição das águas por herbicidas utilizados no cultivo do arroz irrigado na região central do estado do Rio Grande do Sul, Brasil: predição teórica e monitoramento
This article presents an evaluation of the pollution of river water by herbicides used in the culture of irrigated rice in Rio Grande do Sul State, Brazil. Firstly, a theoretical evaluation was made using the approaches suggested by EPA-USA, the "Groundwater Ubiquity Score" index and the Goss method to estimate the pollution possibilities. Afterwards, a moni

19. PrÃ-seleÃÃo e prÃ-carga de dados para bancos de dados mÃveis
One of the main goals of mobile data access is to reach the ubiquity inherent to the mobile systems: to access information regardless of time and place. Due to mobile systems restrictions such as, for instance, limited memory and narrow bandwidth, it is only natural that researchers expend efforts to soothe such issues. This work will approach issues regardi

20. O primado da percepção digital e suas consequências no ambiente midiático. / The primacy of perception and its consequences in the mediatic environment
The goal of this research is to examine aspects of contemporary comunication from a perceptual approach. This hipothesis emerges from authors as distinct as Walter Benjamin, Marshall McLuhan and Vilém Flusser, all of which ascribe large importance to technological mediation in the ways we perceive the world and formalize knowledge. We search to verify by wh

21. DANCE: Uma infra-estrutura computacional para agentes danÃarinos
Ubiquity is one of the fastest growing characteristics of Informatics. One can find applications from the most usual, such as information processing systems, up to the least expected ones, such as robots that can play soccer. Perhaps, it would not be unusual to state that, nowadays, it is harder to find an area where computers are not applied than the other

22. Distribuição de mercúrio total como indicador de poluição urbana e industrial na costa brasileira
The monitoring of the pollution status of the Brazilian coast is hampered by the lack of a consistent environmental indicator. We propose Hg as an environmental proxy to anthropogenic pollution of coastal regions due to its absence in the Brazilian geology, its ubiquity in anthropogenic effluents, and its toxicity. Available data suggest Hg "backgrounds" in

23. Environmental vulnerability analysis of the main recommended pesticides for cotton, rice, coffee, sugar cane, citrus, corn and soybean production systems / Analise da vulnerabilidade ambiental aos principais pesticidas recomendados para os sistemas de produção de algodão, arroz, café, cana-de-açucar, citros, milho e soja
The utilization of pesticides in agriculture is a necessary practice to control pests, diseases or weeds to reach an excellent index of productivity and get attend the increasing necessity of food. Some of this pesticides applied, show dangerous physical-chemical proprieties to the environmental and health human. Many times it happen because we haven?t enoug

24. UM FRAMEWORK PARA GERÊNCIA DE CONTEXTO ORIENTADO A SISTEMAS HIPERMÍDIA ADAPTATIVOS / CONTEXT MANAGER FRAMEWORK FOR SUPPORTING ADAPTIVE HYPERMEDIA SYSTEMS AND OTHER CONTEXT-AWARE APPLICATIONS
A computação orientada a contexto (Context-Aware Computing) é um paradigma que se propõe a permitir que as aplicações descubram e tirem proveito das informações que as circundam em dado instante, tais como localização, recursos próximos, infra-estrutura disponível, preferências do usuário, além de outras. Muitas pesquisas realizadas nessa áre
