Revista Brasileira de Hematologia e Hemoterapia , 2010, DOI: 10.1590/S1516-84842010000600010
Abstract: introduction: hyperaggregation of platelets can cause the formation of thrombi and subsequent occlusion of blood vessels leading to ischemia. this phenomenon can be responsible for ischemic cardiovascular diseases such as angina pectoris and atherosclerosis as well as other forms of ischemia such as stroke. to decrease platelet function and reduce the formation of thrombi, acetylsalicylic acid has been used for antithrombotic treatment, with several studies showing its effectiveness. therefore it is necessary to use a laboratory tool to monitor the effectiveness of treatment, which is achieved through laboratory testing of platelet aggregation. the aim of this study was to compare two different methods (impedance and turbidimetry) to test platelet aggregation in 30 adult patients of both genders taking acetylsalicylic acid. conclusion: the results show that there is a good correlation between these two methods and so both these techniques can be used in the clinical routine.

Abstract: A Mobilidade populacional na Amaz nia é motivada pela busca de novas oportunidades de trabalho, fato atrelado às mudan as estruturais, relacionadas à a o do Governo Federal por meio de políticas territoriais iniciadas ainda nos anos 60 e 70. A implanta o de projetos de infra-estrutura estabelece diferentes fun es e reestrutura es espaciais, constituindo novos padr es de organiza o social, econ mica e cultural. Atualmente, em Porto Velho-Rond nia, a constru o das hidrelétricas de Jirau e Santo Ant nio, no rio Madeira, iniciadas em 2008, tem sido questionada quanto ao novo fluxo populacional, o qual pode ser caracterizado por dois processos: o de territorializa o e o de desterritorializa o. O primeiro processo é marcado pela atra o populacional, dado pela oferta de trabalho e, o segundo, pautado na desterritorializa o devido ao deslocamento populacional na área do reservatório, apresentando como caso mais crítico o da comunidade de Mutum-Paraná, com o comprometimento total do seu núcleo urbano. O objetivo deste artigo é avaliar a mobilidade populacional e a rela o entre a implanta o de infra-estrutura e explora o dos recursos naturais na área de influência das hidrelétricas. A metodologia parte da análise temporo-espacial com revis o de literatura, trabalho de campo e coleta de dados geográficos da área. As variáveis utilizadas foram: popula o, principais atividades econ micas e normas de uso do território (legisla es). Estas variáveis permitiram compreender as rela es entre sociedade e espa o no seu processo de organiza o e transforma o. As análises indicaram que nesta área, desde sua ocupa o até os dias atuais, a mobilidade populacional tem sido motivada pela implanta o de obras de infra-estrutura, apropria o e explora o intensiva dos recursos naturais sem estabilidade econ mica, resultando em fluxos e refluxos migratórios. La mobilité de la population amazonienne est motivée par la recherche de nouvelles possibilités d’emploi, un fait lié à des changements structurels, liés à l’action du gouvernement fédéral grace à des politiques territoriales ouvertes, même dans les années 60 et 70. La mise en uvre de projets d’infrastructure fournit diverses fonctions et à la restructuration spatiale, formant de nouveaux modes d’organisation sociale, économique et culturel. Actuellement, à Porto Velho, Rond nia, la construction de centrales hydroélectriques Jirau et Santo Ant nio, sur la rivière Madeira, a commencé en 2008, a été interrogé sur le nouvel afflux de population, qui peut être caractérisé par deux cas: celui de la territorialisation
Application of Photo-Fenton Process for the Treatment of Kraft Pulp Mill Effluent  [PDF]
M. D. Rabelo, C. R. Bellato, C. M. Silva, R. B. Ruy, C. A. B. da Silva, W. G. Nunes
Advances in Chemical Engineering and Science (ACES) , 2014, DOI: 10.4236/aces.2014.44050
Abstract: The present work evaluated the use of photo-Fenton process for the treatment of kraft pulp mill effluent. The photo-Fenton best operating conditions, such as pH, concentration, and H2O2: Fe2+ ratio were evaluated. The efficiency of the treatment was measured by COD (chemical oxygen demand) removal. The results showed that the optimum pH for the photo-Fenton process was equal to 3. The increase in H2O2 application resulted in an efficiency increase of the photo-Fenton process, although this was not a directly proportional relation. For most cases, the H2O2: Fe2+ proportion of 100:1 yielded the best results for COD removal. Solar radiation was more efficient than artificial UV to the COD removal. During the treatment the organic matter of the effluent was more oxidized than mineralized, showing a higher removal of COD than BOD (biochemical oxygen demand) and TOC (total organic carbon), respectively. So, photo-Fenton process increased the BOD/ COD ration but decreased the BOD/TOC ratio.

Creative Education (CE) , 2015, DOI: 10.4236/ce.2015.67070
Abstract: This article aims to analyze and discuss the use of digital interactive games, such as learning tools to be used by educators in the classroom, as a resource for geography teaching-learning process in the early grades. This discussion arose from the analysis by geography course graduation students of the Federal University of Pará (UFPA), in the years 2013 and 2014, at which this tool has gained recognition of its potential by students. In this sense, the objective is a brief discussion, based on the analysis of some selected examples on how these digital games can become fundamental importance of resources for teaching Geography and how these should be used and applied in the classroom by educators in a critical way, which will allow students to have adequate learning about the geographic space.
Design Considerations on a Dispersion Compensating Coaxial Fiber
Nunes, F. D.;Silva, H. F. da;Zilio, S. C.;
Brazilian Journal of Physics , 1998, DOI: 10.1590/S0103-97331998000200002
Abstract: this work reports on the performance of a dispersion compensating coaxial fiber as a function of its geometric parameters. our analysis is carried out by solving the wave equation under the linearly polarized approximation, which leads to transcendental equations that provide the effective index of refraction. the highest efficiency at a fixed wavelength is achieved for a suitably chosen geometry and this choice constitutes an important factor to determine the general shape of the wavelength-dependent dispersion curve.
