    ROS-Industrial. Technologies, Trends, Applications

    No full text
    Established already in robotics research, the open source "Robot Operation System (ROS)" ist getting more and more interesting for industrial applications. ROS offers a multitude of intelligent software components, e. g. for 2D-vision and 3D-point cloud sensor processing, as well as robot motion planning. Transferring these capabilities to industrial platforms could revolutionize robotic manufacturing applications. ROS-Industrial will enable more and more flexible automation solutions with exchangable components, that are able to cope with dynamic enviroments and a large diversity of objects to be handled. Although ROS bears a huge potential, there are still some draw backs on comparison to established proprietary industrial software: little longterm evaluations of ROS on shop floors with respect to non-functional requirements like robustness, safety and dependability, no guaranteed support. The ROS-Industrial initiative founded in 2012 aims at eliminating these draw backs and tap the full potential of ROS for industrial robotics. In this conference organized by Fraunhofer IPA, current trends, technologies and experiences from industrial use cases within the European ROS-Industrial community are presented

    Evaluation of the Protective Role of Vitamin E against ROS-Driven Lipid Oxidation in Model Cell Membranes

    Reactive oxygen species (ROS) are chemically reactive oxygen-containing compounds generated by various factors in the body. Antioxidants mitigate the damaging effects of ROS by playing a critical role in regulating redox balance and signaling. In this study, the interplay between reactive oxygen species (ROS) and antioxidants in the context of lipid dynamics were investigated. The interaction between hydrogen peroxide (H2O2) as an ROS and vitamin E (&alpha;-tocopherol) as an antioxidant was examined. Model membranes containing both saturated and unsaturated lipids served as experimental platforms to investigate the influence of H2O2 on phospholipid unsaturation and the role of antioxidants in this process. The results demonstrated that H2O2 has a negative effect on membrane stability and disrupts the lipid membrane structure, whereas the presence of antioxidants protects the lipid membrane from the detrimental effects of ROS. The model membranes used here are a useful tool for understanding ROS&ndash;antioxidant interactions at the molecular level in vitro

    The Comedy of Errors

    No full text
    The Comedy of Errors has been popular on the stage during the last three centuries and has proved itself admirably suited to adaptation as pure farce and musical spectacle. For this updated edition, Ros King has provided a completely new Introduction to the existing text and commentary, in which she argues that the play cannot be regarded merely as a farcical romp based on a classical model, but belongs to the critically misunderstood genre of tragi-comedy. In stressing the seriousness which underlies the story, the Introduction picks out the play's religious imagery for special attention, whilst also engaging fully with the play's deft lightness of touch and its continuing popularity in the theatre. A fresh Reading List guides the reader towards further study. Updated edition of a text which has been in the series since 1988; completely new Introduction by Ros King, Queen Mary, University of London; new production photographs and a revised reading list.Contents:List of illustrations; Acknowledgements; Preface to first edition; Abbreviations; Introduction by Ros King: Shakespeare's main source: Plautus's Menaechmi; Shakespeare's first tragicomedy; Shakespeare's schooling and the construction of The Comedy of Errors; Casting the twins; Verse form and metrication; The first known performance: Gray's Inn 1594; Later productions; Note on the text; List of characters; THE PLAY; Appendixes: 1.

    Learning Management in Higher Education and Social Web. Integration into Instructional Design by Early Adopters

    No full text
    This work originates in a proposal for features and quality indicators, published as "Quality Assessment in Social Learning Environments" (Zapata-Ros, 2011) on the integration of learning web management systems and social environments in the Higher Education. The work proposes the validation of the indicators and the need for a framework for a pedagogical model and an instructional design

    Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências da Saúde. Programa de Pós-Graduação em Saúde Pública.Esta pesquisa se propõe a contribuir com a discussão do papel do setor saúde na busca por vidas mais longas e saudáveis, ajudando na ressignificação corrente dos objetivos desta área do conhecimento e influenciando, por conseqüência, na assistência prestada e nos seus métodos de intervenção. Procurando traçar paralelos entre vários conceitos, faz-se um recorte teórico e encontra-se a possibilidade de se entender o bem-estar subjetivo como expressão da Promoção da Saúde. Podendo ser compreendido coloquialmente como felicidade, o bem-estar subjetivo acaba por ser apontado como item imprescindível para o entendimento dos conceitos de Promoção da Saúde e Qualidade de vida e para a possibilidade de um olhar diferenciado sobre os determinantes da longevidade. Observou-se que a partir de um patamar digno de condições socioeconômicas, a contribuição das questões materiais e objetivas para a longevidade não é comprovada. Este estudo objetivou identificar aspectos presentes ao longo da vida de sujeitos de pesquisa longevos e discutir a ligação desses aspectos com a longevidade. A pesquisa foi realizada pelo método de História de Vida na cidade de Antonio Carlos (SC), a 2a cidade em expectativa de vida no Brasil e que detém bons Índice de Desenvolvimento Humano e Índice de Exclusão Social. Encontrou-se a associação da longevidade com as categorias ocupação, autonomia, resiliência, solidariedade, espiritualidade, sentimento de realização, relacionamentos afetivos, celebração e esperança

    NADPH oxidase (NOX) in the heart : the interplay of NOX-derived ROS in β1-integrin-induced survival signalling

    No full text
    Moderate levels of reactive oxygen species (ROS) act as mediators in cellular signalling processes. An important source of cardiac ROS is the highly expressed NADPH oxidase (NOX) family isoform NOX2. However, little is known about whether NOX-derived ROS are protective in the heart. In this study we show that CD29 (β1-integrin), a cell adhesion receptor highly expressed on cardiac muscle cells, induces NOX-dependent ROS. CD29 is known to be mandatory in cell growth and survival, and non-functional CD29 causes severe heart disease. We demonstrate that NOX2-derived ROS are essential for CD29-induced survival signalling, including the PI3K/PKB and MEK/ERK pathways. Furthermore, CD29-induced NOX-derived ROS are indispensible in the inhibition of the pro-apoptotic kinase GSK-3β, which we uncovered as a downstream target of both the ERK and PKB survival pathways in cardiac muscle cells. These findings clearly add to the growing body of evidence suggesting that moderate ROS levels are beneficial to the cell and highlight the crucial role of NOX2-derived ROS for cell survival in the heart

    Going Beyond Counting First Authors in Author Co-citation Analysis

    No full text
    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
