John Conway e o seu Jogo da Vida

Apresenta-se uma biografia sucinta de John Horton Conway, matemático nascido em 1937 em Liverpool. Conway tornou-se bem conhecido após a sua invenção do Jogo da Vida, o qual é um exemplo de auto-organização e interessante para biólogos, matemáticos, economistas, filósofos e público em geral.

On the choice of posittioning and cluster size for fixed relay stations in a LTE network

The long term evolution (LTE) is one of the latest standards in the mobile communications market. To achieve its performance, LTE networks use several techniques, such as multi-carrier technique, multiple-input-multiple-output and cooperative communications. Inside cooperative communications, this paper focuses on the fixed relaying technique, presenting a way for determining the best position to deploy the relay station (RS), from a set of empirical good solutions, and also to quantify the associated performance gain using different cluster size configurations. The best RS position was obtained through realistic simulations, which set it as the middle of the cell's circumference arc. Additionally, it also confirmed that network's performance is improved when the number of RSs is increased. It was possible to conclude that, for each deployed RS, the percentage of area served by an RS increases about 10 %. Furthermore, the mean data rate in the cell has been increased by approximately 60 % through the use of RSs. Finally, a given scenario with a larger number of RSs, can experience the same performance as an equivalent scenario without RSs, but with higher reuse distance. This conduces to a compromise solution between RS installation and cluster size, in order to maximize capacity, as well as performance.

Blood-sucking lice may disseminate Trypanosoma cruzi infection in baboons

Trypanosoma cruzi (Schyzotrypanum, Chagas, 1909), and Chagas disease are endemic in captive-reared baboons at the Southwest Foundation for Biomedical Research, San Antonio, Texas. We obtained PCR amplification products from DNA extracted from sucking lice collected from the hair and skin of T. cruzi-infected baboons, with specific nested sets of primers for the protozoan kinetoplast DNA, and nuclear DNA. These products were hybridized to their complementary internal sequences. Selected sequences were cloned and sequencing established the presence of T. cruzi nuclear DNA, and minicircle kDNA. Competitive PCR with a kDNA set of primers determined the quantity of approximately 23.9 ± 18.2 T. cruzi per louse. This finding suggests that the louse may be a vector incidentally contributing to the dissemination of T. cruzi infection in the baboon colony.

Os Forais de Setúbal [1249-1514]. Apresentação de documentos. A importância dos estudos históricos na economia e sustentabilidade locais

Esta comunicação, no âmbito da realização do II Encontro de Estudos Locais do Distrito de Setúbal, pretendeu apresentar os resultados preliminares da primeira fase de uma investigação em torno dos forais de Setúbal (1249/1514), projecto que culminará em 2014 com a publicação do estudo destes documentos. Pretendeu-se igualmente ressalvar o papel da investigação histórica na região, destacando-se as suas potencialidades ao nível da sustentabilidade e do desenvolvimento da comunidade local
