    A Lifecycle Model for the Environmental and Economic Assessment of Selective Laser Melting Processes

    No full text
    Additive Manufacturing (AM) is a promising technology that fosters innovation and increases designers’ freedom. Considering the sustainability performances, AM technologies seem to have significant potential since they produce reduced or near-zero waste. However, the advantages depend on the specific application, especially in the context of metal AM, and need to be evaluated from a lifecycle perspective. The present paper proposes a simplified model for the economic and environmental sustainability assessment of the metal Selective Laser Melting (SLM) process. The model is grounded on mapping the main phases and related energy/materials flows, included in the lifecycle of an AM manufactured part (raw material, manufacturing, use end of life, transport). The preliminary tests, realized in the context of a motorbike application, confirmed that the lifecycle perspective of the model is an essential feature to guide the decision-making both during the design process and in later stages of product development

    Excellent intra and inter-observer reproducibility of wrist circumference measurements in obese children and adolescents

    In a previous study, we found that wrist circumference, in particular its bone component,was associated with insulin resistance in a population of overweight/obese children. Theaim of the present study was to evaluate the intra- and inter-operator variability in wrist cir-cumference measurement in a population of obese children and adolescents. One hundredand two (54 male and 48 female) obese children and adolescents were consecutivelyenrolled. In all subjects wrist circumferences were measured by two different operators twotimes to assess intra- and inter-operator variability. Statistical analysis was performed usingSAS v.9.4 and JMP v.12. Measurements of wrist circumference showed excellent inter-operator reliability with Intra class Correlation Coefficients (ICC) of 0.96 and ICC of 0.97 forthe first and the second measurement, respectively. The intra-operator reliability was, also,very strong with a Concordance Correlation Coefficient (CCC) of 0.98 for both operators.The high reproducibility demonstrated in our results suggests that wrist circumference mea-surement, being safe, non-invasive and repeatable can be easily used in out-patient set-tings to identify youths with increased risk of insulin-resistance. This can avoid testing theentire population of overweight/obese children for insulin resistance parameter

    “Dialogue between Translators and Authors. The Example of Claudio Magris”

    No full text
    The paper focuses on the forms of cooperation between authors and their translator(s) in all cases in which the two operate simultaneously. This issue is explored on the example of the Trieste-born author Claudio Magris, who cultivates a very close relationship with most of his translators. Writing and translation have been coexisting in this author throughout his career and have resulted in the heightened sensitivity of Magris the author with regards to translation, as the first part of the analysis shows. The second part describes the dialogue between Magris and the translators of his works, and ends with the more general question of the significance and role of such a form of exchange

    Consideraciones sobre la poética de Claudio Rodríguez

    The purpose of this paper is to study the poetics of Claudio Rodríguez, delimiting its components and trying to clarify them and to present them as a whole. The author left some pages written on his conception of poetry that encourage reflection and, in some cases, interpretation. So with his conception of poetry as a gift and inebriation, as an alliance and condemnation or celebration (giving title to his collections of poems), or with notions such as «participation», «living contemplation», «living expression » or «personal rhythm» that make up his way of understanding the poetic process.El propósito de este artículo es estudiar la poética de Claudio Rodríguez, deslindando sus componentes y tratando de clarificarlos y presentarlos en su conjunto. El autor dejó escritas algunas páginas sobre su concepción de la poesía que animan a la reflexión y, en algunos casos, a la interpretación. Así sucede con su concepción de la poesía como un don y una ebriedad, como alianza y condena o como celebración (que dan título a sus poemarios), o con nociones como las de «participación», «contemplación viva», «expresión viva» o «ritmo personal», que configuran su forma de entender el proceso poético

    The impact of nonalcoholic fatty liver disease on renal function in children with overweight/obesity

    The association between nonalcoholic fatty liver disease (NAFLD) and chronic kidney disease has attracted interest and attention over recent years. However, no data are available in children. We determined whether children with NAFLD show signs of renal functional alterations, as determined by estimated glomerular filtration rate (eGFR) and urinary albumin excretion. We studied 596 children with overweight/obesity, 268 with NAFLD (hepatic fat fraction >= 5% on magnetic resonance imaging) and 328 without NAFLD, and 130 healthy normal-weight controls. Decreased GFR was defined as eGFR < 90 mL/min/1.73 m(2). Abnormal albuminuria was defined as urinary excretion of >= 30 mg/24 h of albumin. A greater prevalence of eGFR < 90 mL/min/1.73 m2 was observed in patients with NAFLD compared to those without liver involvement and healthy subjects (17.5% vs. 6.7% vs. 0.77%; p < 0.0001). The proportion of children with abnormal albuminuria was also higher in the NAFLD group compared to those without NAFLD, and controls (9.3% vs. 4.0% vs. 0; p < 0.0001). Multivariate logistic regression analysis revealed that NAFLD was associated with decreased eGFR and/or microalbuminuria (odds ratio, 2.54 (confidence interval, 1.16-5.57); p < 0.05) independently of anthropometric and clinical variables. Children with NAFLD are at risk for early renal dysfunction. Recognition of this abnormality in the young may help to prevent the ongoing development of the disease
