Reuse of clean waste from the fashion industry in sustainable design development with a focus on social responsibility

The present article relates the concept of design in the social sustainability focusing on the environmental issues in vogue, threatened under an excessive generation of clean solid wastes during the mass production of products from existing industries, textiles and footwear, towards the consume of today's societies. The search for imminent solutions face to this problem are centralized on the sustainable design, aiming essentially the co-design based on upcycling principles and the methods of modular design, between designers and young adults with intellectual or physical disabilities, with intention to make creative proposals for new fashion products more sustainable, differentiated and with added value. In this mode, comes up the importance of a more social and ethical design, giving the participatory opportunity between amateurs and professionals to minimize the resources and production processes, and optimizing the life cycle of the product.FEDER funds through the Competitivity Factors Operational Programme - COMPETE and by national funds through FCT – Foundation for Science and Technology within the scope of the project POCI-01-0145-FEDER-007136

Approch to the knowledge of Coccinellidade (Coleoptera) species diversity of Madeira and Porto Santo Islands.

Proceedings of the 8th International Symposium on Ecology of Aphidophaga: Biology, Ecology and Behaviour of Aphidophagous Insects.We present a list of coccinellids collected in Madeira archipelago and notice the presence of two new species; of Scymnini; Scymnus (Scymnus) abietis (Paykull) and Nephus hiekei Fürsch. We analyse the distribution and abundance at the community level, using the following measures: species richness index, abundance and relative abundance, similarity index, diversity, and evenness. 13 species from 3 families were recorded. Hippodamia variegata was the most abundant one with 29.7 % of the 141 specimens collected. Two main groups of relative abundance were identified. The first group included the 6 most common H. variegata, S. interruptus, C. arcuatus, C. septempunctata, S. levaillanti and R. litura and the second one included S. abietis, L. lophante and R. chrysomeloides. Diversity index values are relatively high. The 6 most common species comprised more than 90 % of the individuals without a very different relative abundance. Many factors other than extinction and immigration could explain the variation of the number of species on islands. The highest number of species collected in Madeira island, compared to Porto Santo, could be related with its higher elevation, soil and substrate types, plant species richness, number of habitat, habitats diversity, structure and heterogeneity of the former

Evidence for entanglement at high temperatures in an engineered molecular magnet

The molecular compound [Fe$_{2}$($\mu_{2}$-oxo)(C$_{3}$H$_{4}$N$_{2}$)$_{6}$(C$_{2}$O$_{4}$)$_{2}$] was designed and synthesized for the first time and its structure was determined using single-crystal X-ray diffraction. The magnetic susceptibility of this compound was measured from 2 to 300 K. The analysis of the susceptibility data using protocols developed for other spin singlet ground-state systems indicates that the quantum entanglement would remain at temperatures up to 732 K, significantly above the highest entanglement temperature reported to date. The large gap between the ground state and the first-excited state (282 K) suggests that the spin system may be somewhat immune to decohering mechanisms. Our measurements strongly suggest that molecular magnets are promising candidate platforms for quantum information processing

Contribution to the knowledge of the Coccinellidae (Insecta: Coleoptera) fauna from the Azores islands.

An updated list of the Coccinellidae species of the Azores archipelago is presented. New records for S. Miguel: Nephus (Sidis) hiekei; Sta. Maria: Rodolia cardinalis; S. Jorge: Stethorus punctilium, Clitosthetus arcuatus, Scymnus nubilus, N. (Sidis) hiekei; Pico: R. cardinalis; Graciosa: C. arcuatus, S. (Scymnus) interruptus, N. (Sidis) hiekei, Lindorus lophantae and R. cardinalis; Corvo: S. nubilus, N. (Sidis) hiekei and Coccinella undecimpunctata. Regressions of species richness against area of the islands and distance from the nearest mainland were performed. No statistical significant correlation between species richness against area was found but a statistical significant negative correlation between the number of species and the distance from the nearest mainland was obtained. The results are, in part, in accordance with the predictions of MACARTHUR & WILSON’S (1967) equilibrium theory of island biogeography, relating differences in the diversity within Azorean islands with isolation

Análise e descrição das tipologias de comunicação para transferência nos dias de campo do programa Terra Sul dos anos de 2008 e 2009.

O objeto deste trabalho é fazer uma análise das tipologias de comunicação para transferência que estão presentes nos dias de campo dos programas Terra Sul, produzidos pela Embrapa Clima Temperado, dividindo-as, basicamente, entre as categorias convencional, informal e construtivista. Observando os dias de campo, analisar quais são as novas maneiras de se fazer comunicação para a transferência

Estoque de carbono e quantificação de substâncias húmicas em latossolo submetido a aplicação contínua de lodo de esgoto.

Este estudo teve como objetivo avaliar o efeito da aplicação contínua de doses de lodo de esgoto oriundo da Estação de Tratamento de Esgoto de Barueri, SP, sobre os teores e estoques de C e sobre as alterações na distribuição de substâncias húmicas em Latossolo Vermelho distroférrico. O experimento foi instalado em 1999, no Campo Experimental da Embrapa Meio Ambiente, em Jaguariúna-SP; os dados foram obtidos após a sexta aplicação de lodo e cultivo sucessivo de milho. Foram utilizadas, nas diferentes parcelas experimentais, as seguintes doses acumuladas de lodo de esgoto (base seca): 0, 30, 60, 120 e 240 Mg ha-1, sendo estudados os tratamentos: (L0) testemunha sem adição de lodo; e aplicação de lodo de esgoto visando fornecer uma (L1), duas (L2), quatro (L4) e oito (L8) vezes a dose de N requerida pelo milho. Foram avaliados os teores e o estoque de C orgânico nas camadas de solo de 0-10, 10-20, 20-40 e 40-60 cm. Os teores de C associados às substâncias húmicas foram avaliados na camada de solo de 0-10 cm. O teor e o estoque de C orgânico aumentaram com o acréscimo nas doses de lodo de esgoto aplicadas, até a camada de solo de 0-20 cm. A maior parte (50-66 %) do C associado às substâncias húmicas está presente no solo na forma de humina, seguido por C-fração ácidos fúlvicos e C-fração ácidos húmicos, nesta ordem. A aplicação de lodo de esgoto implica maior acúmulo de substâncias húmicas no solo, mas as proporções de C-humificado da matéria orgânica não são alteradas

Experimental Determination of Thermal Entanglement in Spin Clusters using Magnetic Susceptibility Measurements

The present work reports an experimental observation of thermal entanglement in a clusterized spin chain formed in the compound Na$_2$Cu$_5$Si$_4$O$_{14}$. The presence of entanglement was investigated through two measured quantities, an Entanglement Witness and the Entanglement of Formation, both derived from the magnetic susceptibility. It was found that pairwise entanglement exists below $\sim 200$ K. Tripartite entanglement was also observed below $\sim 240$ K. A theoretical study of entanglement evolution as a function of applied field and temperature is also presented.Comment: Submited to Phys. Rev.
