Cellular slabs with and without insulation submitted to fire conditions

The wooden cellular slabs are lightweight structures, easy to assemble, and with excellent architectural features, as good thermal and acoustic conditions. The wooden cellular slabs with perforations are typical and very common engineering solutions, used in the ceiling or flooring to improve the acoustic absorption of compartments, and also have a good insulation and relevant architectonic characteristics. However, the high vulnerability of wooden elements submitted to fire conditions requires the evaluation of its structural behaviour with accuracy. The main objective of this work is to present a numerical model to assess the fire resistance of wooden cellular slabs with different perforations. Also the thermal behaviour of the wooden slabs will be compared considering material insulation inside the cavities. The time-temperature history and the residual cross-section of wooden slabs were numerically measured and analysed.

Docência e integração na educação básica em Portugal

No terceiro capítulo – intitulado Docência e integração na educação básica em Portugal – problematiza-se a relação entre a educação tradicional e a educação democrática visando compreender por que é que, sendo mais adequada a pedagogia da participação para o desenvolvimento global da criança, se continua a manter, nas escolas portuguesas, uma pedagogia suportada pela uniformidade de métodos e programas. Metodologicamente fundamentado nos princípios orientadores relativos à investigação-ação, este capítulo estuda as práticas potenciadoras de uma educação integrada e os contributos da formação em contexto. O discurso dos professores envolvidos no estudo realça a parca formação (inicial e contínua) relativamente à prática de um ensino integrado e participado e salienta a compartimentação disciplinar como fator constrangedor. Afirma também a necessidade de redefinição no trabalho do professor, nomeadamente na autorreflexão das práticas, na partilha dessas práticas com os seus pares e no desenvolvimento profissional ao longo da vida. Constata, porém, que o trabalho de cooperação expressa-se sobretudo na partilha a dois. A análise dos discursos atesta também a hipótese das práticas pedagógicas tenderem mais para uma pedagogia transmissiva do que para uma pedagogia da participação.

Rural tourism destination competitiveness: Portugal vs Belarus

This research presents a study aimed to evaluate the performance and competitiveness of tourist destinations in Portugal and Belarus within regions. The evaluation was performed under an analytical tool, Market Share Analysis proposed by Faulkner (1997). In addition, it was used some descriptive statistics. The conducted analysis concluded, with respect to the evolution of the destinations tourism that Açores Island is the most prosperous market for the majority of countries, because most countries staid in the zone of Performing market. North, Lisbon and Algarve regions are maturity markets for the most countries, because they stay in Stagnant markets zone. Centre and Alentejo regions could be attributed Emerging markets for the majority of countries once are developing markets. The major market share is occupied by Portugal practically for all regions, except islands. It is also necessary to underline, that the research was made only within two years (2013 and 2014), because of the lack of necessary information in previous years. In the case of Belarus, it could be mentioned, that rural market of this country is developing (but still mostly with neighbour countries), because the number of entities, participating in rural tourism is growing as the number of foreign tourists.

Microbiological and physicochemical aspects of “salpicão”, a traditional dry sausage produced in the northeast of Portugal

Counts of total viable mesophilic bacteria (TVC), lactic acid bacteria (LAB), Microccocaceae, Enterobacteriaceae, Salmonella spp. and Listeria monocytogenes, in traditional Portuguese dry sausages from two industrial producers, were compared in batter and final product. During the production process, the TVC increased significantly, most likely due to the multiplication of fermentative flora. Enterobacteriaceae decreased from batter to final product while the S. aureus increased. Great variability was verified in detection of L. monocytogenes both between batches and industrial producers
