Raízes portuguesas no design têxtil/moda

O principal objectivo deste artigo é o de documentar a importância das artes e técnicas tradicionais têxteis como motivo e fonte de inspiração para criadores e designers, que aí vão procurar as bases e as raízes para as suas criações. Trata-se de um desafio que consiste em "reinventar o passado", preservar a tradição, procurando nela as origens do design, e de desenvolver novos produtos têxteis e novas funcionalidades a partir de técnicas e saberes manuais capazes de incorporar a inovação em novos tecidos

Desenvolvimento de uma coleção para a marca Guava

O Design de Calçado tem vindo a inovar em Portugal e a sua evolução tem sido exponencial. As marcas portuguesas de calçado têm investido sobre diferentes conceitos nesta área. Destaca-se a marca Guava como sendo uma marca que estuda as formas geométricas no Calçado e reflete esta evolução, tendo sempre em conta, a anatomia do pé para um bom conforto e qualidade do produto, sem esquecer o seu lado ecológico, inerente à marca. Tomando como premissa a questão, Como se desenvolve uma coleção para uma marca de Calçado existente em contexto real de trabalho? O método adaptado consiste numa metodologia mista obtida através de investigação/ação. Esta metodologia dinâmica funciona como um ciclo de planeamento, onde a ação remete para a comprovação de fatos através do desenvolvimento de uma coleção de Calçado, onde a análise e a reconceptualização do problema é implementado e avaliado através da marca Guava

Continuum effects in reactions involving weakly bound nuclei

The relevance of the continuum effects in transfer reactions is discussed in conection with the determination of observables of astrophysical interest. In particular, we examine the validity of the Distorted Wave Born Approximation (DWBA) as a tool to extract the astrophysical \emph{(S_{17}(0))} factor. For this purpose, we present calculations for the reaction (^{14})N((^{7} )Be,(^{8})B)(^{13})C comparing the DWBA method with the more sophysticated CDCC-Born approximationComment: Contribution to International Symposium on Physics of Unstable Nuclei (ISPUN02) Halong Bay (Vietnam) November 20 to 25, 2002.

O vestuário profissional enquanto elemento de identidade corporativa – um caso prático ao serviço do Centro Hospitalar da Cova da Beira

O presente artigo expõe o projeto de índole curricular em desenvolvimento e tem como finalidade demonstrar que o vestuário profissional (fardamento) representa um canal de difusão da imagem de uma instituição e pode ser promotor da sua identidade visual. Cada vez mais e nas diversificadas situações, o fardamento tem problemas que um designer de vestuário e têxtil pode solucionar. Conhecedores de algumas necessidades ao nível do fardamento, os responsáveis do Departamento de Comunicação e Marketing do Centro Hospitalar Cova da Beira (C.H.C.B.), comunicaram o seu interesse na possibilidade de reavaliação do caráter visual do vestuário profissional ao nível de front office, solicitando a apresentação de soluções práticas para a inexistência de vestuário profissional uniformizado. Desta forma, delineou-se como objetivo geral para o projeto, a Criação de uma proposta de fardamento e acessórios para os profissionais das unidades de atendimento (front office) do C.H.C.B. com base numa nova Identidade Visual Corporativa, garantindo o conforto no desempenho das várias atividades e funções. É certo que a imagem de uma instituição perante a perceção do público, nasce de uma quantidade de elementos que refletem os seus valores, a sua atividade e o seu profissionalismo. Hoje em dia, essa identidade não aparece só nos estacionários mas também, e cada vez mais frequente, no fardamento que os colaboradores vestem e exibem

Changing elderlies strength levels with a four months multicomponent training program

The multicomponent training seems to positively influence elderly’s physical fitness. It is unclear the effects of this type of training with less intervention time in strength levels. Thus, the aim of this study was to assess the effects of a multicomponent training program with four months in elderly’s strength levels. The sample of this study was composed by 30 subjects with 69.30 (± 5.45) years old and 71.80 (± 8.97) Kg. Body weight was assessed with a bioimpedance balance. The knee flection and extension, arm curl and abduction were assessed with a strain gauge in kilograms of force (Kgf). There were no significant differences between the two moments. However, the mean body weight, knee flection and extension strength levels increased. A four months multicomponent training program seem to be insufficient to improve strength levels in elderlies.info:eu-repo/semantics/publishedVersio

Electrogenerated hydrophilic carbon nanomaterials with tailored electrocatalytic activity

This work investigates the influence of the type of buffer electrolyte used in the generation of Electrochemical Hydrophilic Carbon (EHC) on their physical-chemical properties and electrocatalytic activity. The EHC nanomaterials were prepared in three different biological buffers, phosphate, glycine and citrate buffers (EHC@phosphate, EHC@glycine, EHC@citrate) and their surface properties were fully characterized by AFM, XPS and Raman. The EHC nanomaterials drop cast onto a glassy carbon electrode were electrochemically characterized in [Fe(CN)6]3-/4- and [Ru(NH3)6]3+/2+ redox probes solutions, and their electrocatalytic activity was investigated towards hydrogen peroxide and oxygen reduction reactions (ORR) in a phosphate buffer solution. It was found that the nature of buffer electrolyte strongly influences the surface chemical state of the EHC materials, disorder degree in the hexagonal sp2 carbon network and oxygen functional groups, affecting both the EHC electrocatalytic activity towards the ORR and H2O2 reduction reaction. The most catalytic material for the ORR was EHC@citrate, whereas EHC@glycine showed the highest oxygen conversion (n ≅ 2.7 to 3). Moreover, it was shown that the content of oxygen singly bonded to carbon correlates strongly with the number of electrons transferred. A very singular behaviour in the electrochemical reduction of hydrogen peroxide was observed on EHC@glycine, qualitatively interpreted as an autocatalytic reaction. In contrast, a blocking-like effect was depicted on EHC@phosphate. These results must have an important impact in the development of materials with peroxidase-like activity and in the design of O2 sensors with non-sensitivity to H2O2.publishe

Macronutrient Uptake And Removal By Upland Rice Cultivars With Different Plant Architecture

Modern high-yielding rice cultivars possibly take up and remove greater quantities of macronutrients than traditional and intermediate cultivars. This study was carried out with the aim of evaluating the extraction and removal of macronutrients by upland rice cultivars. These information are of utmost importance for the correct fertilizer management. The treatments consisted of three upland rice cultivars (Caiapó, a traditional type; BRS Primavera, an intermediate type; and Maravilha, a modern type). Macronutrient accumulation by rice cultivars up to the end of tillering (46 DAE) accounted for only 25 % of the total N and P, and between 35-45 % of the total K, Ca, Mg, and S; after that time, accumulation was intensified. In all of the cultivars, the period of greatest nutrient uptake occurred from 45 to 60 DAE for K, Ca, Mg, and S, and after 65 DAE for N. Phosphorus was taken up at greater rates at 70 DAE by the cultivar BRS Primavera and after 90 DAE by the cultivars Caiapó and Maravilha. The cultivars of the traditional (Caiapó) and intermediate (BRS Primavera) groups took up greater amounts of Ca (143 kg ha-1), Mg (46-53 kg ha-1), and S (45-52 kg ha-1), but amounts of N (147-156 kg ha-1) and P (18-19 kg ha-1) were similar to those of the cultivar of the modern group (Maravilha). Caiapó cultivar took up more K (245 kg ha-1) than other cultivars (204-207 kg ha-1). The cultivars Caiapó and Maravilha showed similar grain yield (4,157 and 4,094 kg ha-1); however, this was lower than the grain yield of cultivar BRS Primavera (6,010 kg ha-1). Cultivars with greater yield levels did not necessarily exhibit a greater uptake and removal of nutrients per area, even if they had greater capacity for conversion of the nutrients taken up into the biomass. © 2016, Revista Brasileira de Ciencia do Solo.

Perigos e riscos bacteriologicos associados ao consumo de pescado no Brasil

SUMMARY The present study is a review of data available in Brazil on bacterial diseases transmitted through the consumption of seafood and related products. Data are presented regarding outbreaks and cases of disease and laboratory findings associated with pathogens in seafood and related products, and methods for prevention and control are described.RESUMO Esta revisão apresenta dados qualitativos e quantitativos sobre doenças bacterianas e achados laboratoriais associados ao consumo de pescado e derivados no Brasil de 1983 a 2011. Os resultados mostram uma séria lacuna de dados epidemiológicos relacionados a surtos causados por pescado. Os poucos dados disponíveis indicam que em contraste com outros surtos alimentares transmitidos por carne, aves, laticínios e vegetais, as bactérias patogênicas teriam um menor destaque na transmissão destas doenças pelo consumo de pescado e derivados. Vibrio parahaemolyticus parece ser a causa mais frequente das doenças causadas pelo consumo de pescado e derivados, bem como a bactéria patogênica mais comumente presente nesses produtos nas investigações laboratoriais

A Ranking Method to Prioritize VFR Airports to Be Provided With Instrument Approach Procedures

The primary purpose of this work is to investigate the necessity of a more comprehensive and systematic method to prioritize airports to be provided with instrument approach and landing procedures in the Brazilian air transportation landscape. An overview of the main contributors to risks associated with the approach and landing phases is provided, covering the most important aspects of unstable approaches and CFIT events. Considering the emergence of Terrain Awareness and Alerting Systems (TAWS), the role of its contribution to safety is discussed, as well as the certification context related to the design, installation, and operation of those systems. A ranking method is developed based on the analysis of TAWS alert events in several Brazilian airports. The method results in a ranking list of airports eligible for instrument procedures and points to objective means to improve safety, accessibility, and efficiency on the flight operations to those locations

Use of Visible and Short-Wave Near-Infrared Hyperspectral Imaging to Fingerprint Anthocyanins in Intact Grape Berries

In red grape berries, anthocyanins account for about 50% of the skin phenols and are responsible for the final wine color. Individual anthocyanin levels and compositional profiles vary with cultivar, maturity, season, region, and yield and have been proposed as chemical markers to differentiate wines and to provide valuable information regarding the adulteration of musts and wines. A fast, easy, solvent-free, nondestructive method based on visible, short-wave, and near-infrared hyperspectral imaging (HSI) in intact grape berries to fingerprint the color pigments in eight different grape varieties was developed and tested against HPLC. Predictive models based on modified partial least-squares (MPLS) were built for 14 individual anthocyanins with coefficients of determination of cross-validation (R2 CV) ranging from 0.70 to 0.93. For the grouping of total and nonacylated anthocyanins, external validation was conducted with coefficient of determination of prediction (R2 P) of 0.86. HSI could potentially become an alternative to HPLC with reduced analysis time and labor costs while providing reliable and robust information on the anthocyanin composition of grape berries. © 2016 American Chemical Society
