The aim of this work was to compare the evolution of chronic chagasic untreated patients (UTPs) with that of benznidazole or nifurtimox-treated patients (TPs). A longitudinal study from a low endemic area (Santa Fe city, Argentina) was performed during an average period of 14 years. Serological and parasitological analyses with clinical exams, ECG and X-chest ray were carried out. At the onset, 19/198 infected patients showed chagasic cardiomyopathy (CrChM) while 179 were asymptomatic. In this latter group the frequency of CrChM during the follow-up was lower in TPs compared with UTPs (3.2% vs 7%). Within the CrChM group, 2/5 TPs showed aggravated myopathy whereas this happened in 9/14 UTPs. Comparing the clinical evolution of all patients, 5.9% of TPs and 13% of UTPs had unfavourable evolution, but the difference is not statistically relevant. Serological titers were assessed by IIF. Titers equal to or lower than 1/64 were obtained in 86% of the TPs, but only in 38% of UTPs. The differences were statistically significant (geometric mean: 49.36 vs. 98.2). Antiparasitic assessment of the drugs (xenodiagnosis) proved to be effective. The low sensitivity in chronic chagasic patients must be born in mind. Despite treated patients showed a better clinical evolution and lower antibody levels than untreated ones, it is necessary to carry on doing research in order to improve therapeutic guidelines, according to the risk/benefit equation and based on scientific and ethical principles.

No actual quadro de desenvolvimento das sociedades, onde crescimento nem sempre significa desenvolvimento, torna-se necessário e gerir o território de forma eficaz, dando resposta a diferentes necessidades e motivações. A sua análise e compreensão tem catalisado o desenvolvimento de modelos conceptuais que têm trazido melhorias para os territórios, tanto na organização como na qualidade dos espaços urbanos. Em Portugal, o estabelecimento de estratégias e políticas para a melhoria das áreas urbanas têm feito crescer o interesse por estas temáticas. No entanto, critérios de avaliação e modelos de certificação adequados ao contexto nacional, compõem um tópico que carece ainda de investigação mais aprofundada. O desenvolvimento deste tipo de instrumentos pode servir como referencial para o desenvolvimento de processos de planeamento, incentivando uma saudável competitividade territorial. A criação de políticas Europeias e nacionais poderão ter assim uma excelente base para a definição de ponderações, aquando da distribuição de financiamentos, fundamentais ao desenvolvimento dos territórios. Esta comunicação terá como objectivos: 1. Apresentar um conjunto de critérios de certificação ambiental em áreas urbanas; 2. Demostrar que a certificação ambiental é fundamental para a competitividade dos territórios e para avaliação das melhores práticas de sustentabilidade; 3. Constatar que este tipo de práticas poderá criar uma

Advances in technology have produced more and more intricate industrial systems, such as nuclear power plants, chemical centers and petroleum platforms. Such complex plants exhibit multiple interactions among smaller units and human operators, rising potentially disastrous failure, which can propagate across subsystem boundaries. This paper analyzes industrial accident data-series in the perspective of statistical physics and dynamical systems. Global data is collected from the Emergency Events Database (EM-DAT) during the time period from year 1903 up to 2012. The statistical distributions of the number of fatalities caused by industrial accidents reveal Power Law (PL) behavior. We analyze the evolution of the PL parameters over time and observe a remarkable increment in the PL exponent during the last years. PL behavior allows prediction by extrapolation over a wide range of scales. In a complementary line of thought, we compare the data using appropriate indices and use different visualization techniques to correlate and to extract relationships among industrial accident events. This study contributes to better understand the complexity of modern industrial accidents and their ruling principles.

The aim of this paper is to present the main Portuguese results from a multi-national study on reading format preferences and behaviors from undergraduate students from Polytechnic Institute of Porto (Portugal). For this purpose we apply an adaptation of the Academic Reading Questionnaire previously created by Mizrachi (2014). This survey instrument has 14 Likert-style statements regarding the format influence in the students reading behavior, including aspects such as ability to remember, feelings about access convenience, active engagement with the text by highlighting and annotating, and ability to review and concentrate on the text. The importance of the language and dimension of the text to determine the preference format is also inquired. Students are also asked about the electronic device they use to read digital documents. Finally, some demographic and academic data were gathered. The analysis of the results will be contextualized on a review of the literature concerning youngsters reading format preferences. The format (digital or print) in which a text is displayed and read can impact comprehension, which is an important information literacy skill. This is a quite relevant issue for class readings in academic context because it impacts learning. On the other hand, students preferences on reading formats will influence the use of library services. However, literature is not unanimous on this subject. Woody, Daniel and Baker (2010) concluded that the experience of reading is not the same in electronic or print context and that students prefer print books than e-books. This thesis is reinforced by Ji, Michaels and Waterman (2014) which report that among 101 undergraduates the large majority self-reported to read and learn more when they use printed format despite the fact that they prefer electronically supplied readings instead of those supplied in printed form. On the other side, Rockinson-Szapkiw, et al (2013) conducted a study were they demonstrate that e-textbook is as effective for learning as the traditional textbook and that students who choose e-textbook had significantly higher perceived learning than students who chose to use print textbooks.

Esta comunicação tem como objectivo discutir a validade da Hipótese da Transição da MobiUdade Territorial de Zelinski no mundo globalizado actual. Nas últimas décadas, poucos têm sido os contiibutos conceptuais e teóricos para a problemática da mobilidade territorial. A Hipótese da Transição da Mobilidade Territorial do geógrafo americano Wilbur Zelinski publicada na Geographical Review, em 1971, continua a ser uma grande contiibuição nesse sentido. Merece, assim, atenção especial dos cientistas sociais empenhados na teorização e conceptualização da mobilidade espacial. Zelinski (1971: 221-222) resumiu a sua Hipótese na seguinte sentença: Há regularidades bem definidas e padronizadas no crescimento da mobilidade pessoal através do espaço-tempo nos períodos recentes da História e essas regularidades são um componente fundamental do processo de modernização.

One parameter that influences the adhesively bonded joints performance is the adhesive layer thickness. Hence, its effect has to be investigated experimentally and should be taken into consideration in the design of adhesive joints. Most of the results from literature are for typical structural epoxy adhesives which are generally formulated to perform in thin sections. However, polyurethane adhesives are designed to perform in thicker sections and might have a different behavior as a function of adhesive thickness. In this study, the effect of adhesive thickness on the mechanical behavior of a structural polyurethane adhesive was investigated. The mode I fracture toughness of the adhesive was measured using double-cantilever beam (DCB) tests with various thicknesses of the adhesive layer ranging from 0.2 to 2 mm. In addition, single lap joints (SLJs) were fabricated and tested to assess the influence of adhesive thickness on the lap-shear strength of the adhesive. An increasing fracture toughness with increasing adhesive thickness was found. The lap-shear strength decreases as the adhesive layer gets thicker, but in contrast to joints with brittle adhesives the decrease trend was less pronounced.
