Geotermia superficial em Portugal: Contributos da experiência espanhola, liço...

HVAC (Heating, Ventilating and Air Conditioning) heating and cooling systems are responsible for the largest share of energy use in buildings and play an important role as they represent 40% of the energy consumption in Europe and 36% of the Greenhouse Gases. In this context, heat pumps have positioned themselves in the market as the most appropriate solution for saving emissions, as demonstrated by the high le...

Morphological changes in Bombyx Mori silk gland and gut, in association with th...

The Bombyx mori silkworm is very important econom- ically and is a model for several studies. The larval life of silkworms is divided into five instars. The 5th instar is the longest, where the larvae show maximum food consumption and growth. The silk is produced in a paired gland composed of glandular epithelium and a lumen. Food digestion occurs in the midgut, represented by a folded columnar monolayered epit...

In-situ and laboratory airtightness tests of structural insulated panels (SIPs)...

One of the main factors influencing building airtightness is the construction typology. As building environmental performance requirements raise so does the prevalence of less conventional envelope construction systems as modular structural insulated panels (SIPs) buildings. In this paper, the airtightness performance of a constructive solution based on SIPs was evaluated. Airtightness tests were performed on t...

A importância da permeabilidade na avaliação do desempenho de sistemas de venti...

A permeabilidade da envolvente é um parâmetro fundamental na avaliação do desempenho energético dos edifícios, uma vez que permite avaliar as trocas de ar não controladas. O parâmetro mais utilizado para quantificar a permeabilidade é o número de renovações horárias para um diferencial de pressão de 50 Pa (n50), que pode ser determinado experimentalmente com recurso a uma porta ventiladora. No âmbito do Regulam...

Railway occupant passive safety improvement by optimal design

This work presents a systematic approach to the railway occupant passive safety improvement of seating layouts using optimisation methods for the identification of the best design options. The numerical model of this layout is developed using multibody models for the dummies and finite element models for the vehicle interiors, such as seats and any structural part considered as potential target surface during i...

Debating health and migrations in a context of intense human mobility (Article)...

'The place i long to be': Resilience processes in migrants

Migration has been addressed in studies with a marked focus on its obstacles and difficulties, particularly in the contact with the host country. Recognizing that migrating is a complex process that involves several hardships, it is imperative to understand how migrants overcome adversity and to become aware of the resources mobilised to be cultural adjusted. Based on the theoretical perspective of resilience, ...

Caracterização patológica e construtiva de igrejas e capelas do concelho de Est...

Este estudo pretende enfatizar a importância de caracterizar construtivamente e avaliar a preservação de imóveis pertencentes ao património social da Câmara Municipal de Estarreja, ou seja, a sua herança religiosa e cultural. São apresentadas 8 fichas criadas especificamente para a inspecção de edifícios religiosos, procurando-se caracterizar os materiais e os sistemas estruturais e identificar os principais si...
