Computational rheology et al. with OpenFOAM® computational library

The current capabilities of numerical codes, able to model very complex processes, and the existing powerful computational resources, clearly promote the advantages of employing numerical modelling tools to assist any design related tasks. For more than a decade, the Computational Rheology Group, from the Institute for Polymers and Composites / University of Minho (IPC/UMinho), has been developing and exploiting modelling codes to aid the design of different tools, with a special focus on polymer processing applications. During the last 5 years, most of the numerical developments done at IPC/UMinho are based on the OpenFOAM® computational library. This talk aims to provide an overview of the computational rheology related work done at IPC/UMinho by a large group of researchers, in many cases in close cooperation with industry, and to report the advantages of using computational codes based on OpenFOAM® to support design activitie

Computational rheology with OpenFOAM® computational library

The current capabilities of numerical codes, which able to model very complex processes, and the existing powerful computational resources, clearly promote the employment of numerical modeling tools to assist design-related tasks. The Computational Rheology Group, from the Institute for Polymers and Composites (IPC) of the University of Minho (UMinho), has been developing and exploiting modeling codes for more than one decade, with a special focus on polymer processing applications. During the last 6 years, most of the numerical developments of the Computational Rheology Group were based on the OpenFOAM® computational library. This talk aims at providing an overview of the computational rheology-related work done at IPC/UMinho, in close cooperation with industry, and at illustrating the advantages of using the computational library OpenFOAM ® for the development of new codes. The presentation will cover both the work done by the group to support the design of polymer processing tools and the development of new solvers in the OpenFOAM® computational library

Processo para produção de filamentos poliméricos piezoeléctricos

A presente invenção consiste num processo para obtenção, em linha e em contínuo, de filamentos têxteis de secção variável que incluem um núcleo composto por: eléctrodos(1) revestidos por dieléctrico piezoactivo(2), que por sua vez está revestido por outro eléctrodo(3) e por uma camada isolante eléctrica(4). Adicionalmente, podem ainda ser acrescentada(s) camada(s) destinada(s) a proporcionar ao filamento uma maior estabilidade estrutural, protecção mecânica, características de toque diferentes do filamento nu ou a possibilidade de ser tingido. O processo de fabrico destes filamentos é baseado em métodos convencionais de co-extrusão nos quais são incorporados novos passos, mais concretamente o estiramento a temperatura controlada que possibilitam a obtenção da fase cristalina adequada do polímero piezoeléctrico e a polarização eléctrica do mesmo e o sistema de recirculação para activação do filamento com propriedades piezoeléctricas por polarização. O filamento piezoeléctrico apresenta propriedades mecânicas que tornam possível a sua integração completa em produtos têxteis, através de processos têxteis convencionais, permitindo a sua utilização como sensor ou actuador mecânico.Fundação para a Ciência e a Tecnologia (FCT

Chave De Identificação Para Licófitas E Samambaias Dos Núcleos Picinguaba E Santa Virgínia, Parque Estadual Da Serra Do Mar, Ubatuba, Sp, Brasil

This work contributes to the knowledge of the fern and lycophytes diversity in the Picinguaba and Santa Virginia Nuclei, Parque Estadual da Serra do Mar (PESM), Ubatuba, São Paulo, Brazil, as well as to provide subsidies to identification of the found taxa in these areas. In total, 30 collecting expeditions were conducted and the vouchers were deposited at UEC Herbarium. We have identified 135 species distributed in 53 genera and 19 families for both areas. The most representative families were Polypodiaceae (28 species) and Dryopteridaceae (19 species), whereas Asplenium (12 species), Blechnum and Elaphoglossum (8 species each) were the most important genera. Epiphytic species predominated (62 overall), probably due to the presence of favorable habitats. Among the taxa, 41 are considered endemic from Brazil, 35 of them endemic to the Brazilian Atlantic Forest. Five species are classified as vulnerable according to the “Official list of endangered species in the State of São Paulo”: Elaphoglossum macahense (Fée) Rosenst., Anetium citrifolium (L.) Splitg., Asplenium muellerianum Rosenst., Cyathea glaziovii (Fée) Domin, and Thelypteris angustifolia (Willd.) Proctor, which emphasizes the importance of preservation areas such as the Parque Estadual da Serra do Mar. An identification key has been elaborated to help with the recognition of these groups in Picinguaba and Santa Virgínia Nuclei. © 2016, Universidade Estadual de Campinas UNICAMP.
