    A conceptual study of spirituality in selected writings of Emile Jaques-Dalcroze

    Several authors have noted that one of Émile Jaques-Dalcroze’s aims was to dissolve the mind–body dualism, typical of Cartesianism. However, there has been little research on the spirit–body connection, as it appears in Jaques-Dalcroze’s writings. The purpose of this document analysis is to understand how a hermeneutic phenomenological model for spirituality in music education can inform our understanding of spirituality in selected writings by Jaques-Dalcroze. In the adapted model holism, balance, aesthetic experience, and movement in time, space, and with energy emerged as core concepts. This gives us a much richer understanding of the Dalcroze approach than has hitherto been available and adds to a growing narrative about the spiritual as it pertains to Jaques-Dalcroze and the approach he initiated

    Hydrogen Motion in Magnesium Hydride by NMR

    In coarse-grained MgH2, the diffusive motion of hydrogen remains too slow (<10^5 hops s^−1) to narrow the H NMR line up to 400 °C. Slow-motion dipolar relaxation time T1D measurements reveal the motion, with hopping rate ωH from 0.1 to 430 s^−1 over the range of 260 to 400 °C, the first direct measurement of H hopping in MgH2. The ωH data are described by an activation energy of 1.72 eV (166 kJ/mol) and attempt frequency of 2.5 × 10^15 s^−1. In ball-milled MgH2 with 0.5 mol % added Nb2O5 catalyst, line-narrowing is evident already at 50 °C. The line shape shows distinct broad and narrow components corresponding to immobile and mobile H, respectively. The fraction of mobile H grows continuously with temperature, reaching ∼30% at 400 °C. This demonstrates that this material’s superior reaction kinetics are due to an increased rate of H motion, in addition to the shorter diffusion paths from ball-milling. In ball-milled MgH2 without additives, the line-narrowed component is weaker and is due, at least in part, to trapped H2 gas. The spin−lattice relaxation rates T1^−1 of all materials are compared, with ball-milling markedly increasing T1^−1. The weak temperature dependence of T1^−1 suggests a mechanism with paramagnetic relaxation centers arising from the mechanical milling

    Eficacia y fitotoxicidad a corto y largo plazo del fosfuro de aluminio contra el picudo rojo de las palmeras sobre ejemplares de palmeras canarias vivas

    El picudo rojo de las palmeras, Rhynchophorus ferrugineus, es un curculiónido nativo del sureste asiático que se ha extendido por todo el mundo debido, principalmente, al movimiento no intencionado de plantas infestadas. Como resultado, esta especie se ha convertido en la plaga más destructiva de palmeras a nivel mundial. La enorme dificultad que conlleva detectar los primeros síntomas de infestación debido a los hábitos crípticos de esta plaga, ha provocado que muchos paises pongan en práctica estrictas normas cuarentenarias en la pre y post entrada de palmeras con el fin de evitar su propagación. Sin embargo, aún no existen protocolos cuarentenarios que permitan asegurar que las palmeras no estén infestadas por este insecto. El objetivo de este estudio fue determinar la eficacia del fosfuro de aluminio, comno tratamiento cuarentenario seguro, contra diferentes estados de desarrollo de R. ferrugineus y comprobar los posibles efectos fitotóxicos producidos por este gas en palmeras canarias vivas. Nuestros resultados confirman que una dosis de 1,14 g metro/cúbico durante 2 días es suficiente para eliminar todos los estados de desarrollo del picudo en palmeras canarias vivas, no observando efectos fitotóxicos sobre las mismas durante un año después del tratamiento. Este procedimiento, se podría aplicar fácilmente en contenedores cerrados utilizados para la exportación de palmeras, pudiendo reducir drásticamente los riesgos asociados al tránsito de palmeras en todo el mundo

    Integration of professional judgement and decision-making in high-level adventure sports coaching practice

    This study examined the integration of professional judgement and decision-making processes in adventure sports coaching. The study utilised a thematic analysis approach to investigate the decision-making practices of a sample of high-level adventure sports coaches over a series of sessions. Results revealed that, in order to make judgements and decisions in practice, expert coaches employ a range of practical and pedagogic management strategies to create and opportunistically use time for decision-making. These approaches include span of control and time management strategies to facilitate the decision-making process regarding risk management, venue selection, aims, objectives, session content, and differentiation of the coaching process. The implication for coaches, coach education, and accreditation is the recognition and training of the approaches that“create time” for the judgements in practice, namely“creating space to think”. The paper concludes by offering a template for a more expertise-focused progression in adventure sports coachin

    Fractura triplana epifisaria distal de tibia: a propósito de un caso con interposición de periostio

    Get PDF
    Se presenta un caso de fractura triplana en 2 fragmentos en un paciente varón de 13 años tratado quirúrgicamente, observando la interposición perióstica en el plano axial a nivel del fragmento antero-externo, que impedía la reducción anatómica de la zona epifisaria articular. Se analiza la anatomía quirúrgica de las fracturas triplanas considerando que esta lesión puede ser más frecuente de lo que se ha informado, y sólo valorada en los casos en que se emplee un abordaje antero-externo.The case of a 13-year-old boy with a two-fragment triplane fracture of the distal epiphysis of the tibia is presented. At surgery, an interposition of the periosteum in the axial plane behind the antero-lateral fragment, preventing the anatomical reduction of the epiphyseal joint surface was found. The surgical anatomy of triplane fractures is review taking into account that this lesion can be more frequent that it has been reported. The true incidence should be evaluated at surgery by antero-lateral approach

    Evaluation of the efficacy of Steinernema carpocapsae in a chitosan formulation against the red palm weevil, Rhynchophorus ferrugineus, in Phoenix canariensis

    The red palm weevil, Rhynchophorus ferrugineus (Olivier) (Coleoptera, Curculionidae), is an important pest of palms. It has recently colonized the Mediterranean Basin, where it is a serious problem on ornamental Phoenix canariensis (Chabaud) palms. The efficacy of Steinernema carpocapsae (Weiser) (Nematoda: Steinernematidae) in a chitosan formulation (Biorend R(A (R))) against this weevil in a semi-field trial including both preventative and curative assays has been studied. Our results prove the potential of this nematode to control R. ferrugineus. Efficacies around 80% were obtained in the curative assay, and up to 98% in the preventative treatment. Applications repeated every 2-3 weeks during the critical flight periods could prove effective to protect palms from this weevil in the Mediterranean Basin

    IEA-EBC Annex 68: Indoor Air Quality Design and Control in Low Energy Residential Buildings investigates how to ensure that future low energy buildings are able to improve their energy performance while still providing comfortable and healthy indoor environments. More specifically, Subtask 5 of Annex 68 has dealt with generation of data for the verification of the models and strategies developed in the other Annex 68 Subtasks through controlled field tests and case study presentations
