Effect of material and structural factors on fracture behaviour of mineralised collagen microfibril using finite element simulation - Abdelwahed Barkaoui; Ridha Hambli; João Manuel R. S. Tavares
Bone is a multiscale heterogeneous material and its principal function is to support the body structure and to resist mechanical loads without fracturing. Numerical modelling of biocomposites at different length scales provides an improved understanding of the mechanical behaviour of structures such as bone, and also guides the development of multiscale mechanical models. Here, a three-dimensional nano-scale model of mineralised collagen microfibril based on the finite element method was employed to investigate the effect of material and structural factors on the mechanical equivalent of fracture properties. Fracture stress and damping capacity as functions of the number of cross-links were obtained...
Le fondement quot;initiatiquequot; du discours (post)colonial chez Ahmadou Kourouma - Almeida, José Domingues de
The author proposes an anthropological reading of the (post)colonial fact as it is distilled in the Kourouma#8217;s novels Les soleils des indépendances (1968 and 1970), En attendant le vote des bêtes sauvages (1998) and Allah n#8217;est pas obligé (2000); which releases the relay of a complex semantic and metaphorical network of the changing status of the colonies / African countries at the time of decolonization, that is to say what Ahmadou Kourouma means by quot;suns of independence. The anthropological question, especially about its initiatory ritual component, will prove not accessory or decorative, even exotic, in the work of the Ivorian...
Lhéritage dAhmadou Kourouma dans la littérature contemporaine francophone: le cas de Léonora Miano - Outeirinho, Maria de Fátima
Jean-Michel Djian remarked in his biography on Ahmadou Kourouma (2010): quot;On aurait dit que les Mabanckou, Waberi, Koua-Zotti, Léonora Miano, Kossi Efoui, Fatou Diome, pour n#8217;en citer qu#8217;une petite poignée, attendaient que Kourouma clôture d#8217;une oeuvre magistrale un siècle désenchanté, pour qu#8217;enfin ses #8216;enfants#8217; s#8217;autorisent à ouvrir une nouvelle page littéraire délivrée des scories d#8217;une Afrique épuisée par ses propres ressentiments. In fact, Leonora Miano#8217;s writing is indebted to a postcolonialdiscourse such as Kourouma contributions. Often placed under labels such as those related to the new generation of Migritude or new generation of writers quot;qui se nourrit tout autant de...
Multi-Strategy Learning Made Easy - Francisco Reinaldo; Marcus Siqueira; Rui Camacho; Luis Paulo Reis
This paper presents the AFRANCI tool for the development of Multi-Strategylearning systems. Designing a Multi-Strategy system using AFRANCI is a two step process. The use interactively designs the structure of the system and then chooses the learning strategies for each module. After providing the datasets all modules as automatically trained. The system is aware and takes into consideration the inter-dependency of the modules. The tool has built-in learning algorithms but can use external programs implementing the learning algorithms.The tool has the following facilities. It allows any user to design in an interactive and easy fashion the structure of the target...
Health heat stress in Porto Metropolitan Area : a matter of temperature or (in)adaptation? - Monteiro, Ana; Velho, Sara
The aim of this contribution is to understand the negative outcomes for human health during hot weather in a Mediterranean urban environment. Examining seasonal variations of thermal comfort in Porto, by PhysiologicallyEquivalent Temperature (PET), and comparing expected and observed daily mortality (all causes) and morbidity (all causes, respiratory and circulatory diseases), suggests that in southern Europe, people#8217;s adaptation techniques for reducing heat stress and associated health risks need to be developed much further. Research already done in Porto shows that social and economic vulnerability must be included alongside with individual characteristics, like age, gender or genetics, when defining the thresholds...
