Scalar Field Models: From the Pioneer Anomaly to Astrophysical Constraints

In this work we study how scalar fields may affect solar observables, and use the constraint on the Sun's central temperature to extract bounds on the parameters of relevant models. Also, a scalar field driven by a suitable potential is shown to produce an anomalous acceleration similar to the one found in the Pioneer anomaly.Comment: Seven pages, one figure.

Enseñanza de traducción literaria propuestas didácticas

IX Congresso Brasileiro de Hispanistas realizado nos dias 22 a 25 agosto 2016El objetivo de este trabajo es presentar una propuesta didáctica que pueda ayudar a desarrollar estrategias adecuadas de traducción, que serán utilizadas en la traducción literaria (portugués- español). La traducción literaria forma parte de la traducción especializada, variable de gran dificultad, por lo que es conveniente que el alumno llegue a esta asignatura con una buena competencia lingüística y traductora. Este tipo de traducción ofrece, por lo tanto, la posibilidad de estudiar de forma más completa todos los procedimientos de traducción y puesto que representa una puerta de entrada a obras escritas en otras lenguas, es de fundamental importancia que el futuro traductor literario aprenda a desarrollar ciertas estrategias, así como le corresponde al docente la importante tarea de evaluar el proceso, ya que la evaluación de los méritos creativos y literarios no siempre es objetiva. Una de las estrategias utilizadas es el estudio contrastivo de traducciones como ejercicio didácticoUNILA­-UNIOEST

A moto-mecanización da agricultura en Galiza (1939-2000): políticas de innovación, mercados e sociedades labregas

Esta tese analiza a moto-mecanización da agricultura familiar en Galiza entre 1939 e o ano 2000. lnvestíganse as políticas estatais de innovación, os mercados e as comunidades labregas en relación á introdución de tractores. Centrámonos tanto na evolución da Ditadura franquista dende os anos corenta, como no impacto dos créditos norteamericanos no cambio tecnolóxico. De igual xeito, definimos o paradigma da agricultura industrial na agricultura dos anos sesenta, no que se aplican agresivas políticas de cambio estrutural que continúan en democracia. Dende entón, introdúcense rapidamente tractores ao longo dos anos setenta e oitenta en Galiza. Porén, a velocidade deses cambios tecnolóxicos provocará desequilibrios nas comunidades labregas, e contribuirá ao colapso da agricultura familiar nos anos noventa do século XX

Adolescent hope in the context of nursing care: a scoping review

Problem: Hope is a multidimensional concept with a multidisciplinary approach in different areas of health intervention. From the perspective of the discipline of nursing, the concept of hope in the adolescent has been defined. However, its characterization is not consensually established but is necessary for nurses to be able to plan interventions aimed at its promotion. This scoping review aims at mapping the existing knowledge about adolescent's hope in the context of nursing care and contributing to the improvement of nursing interventions.Eligibility criteria: The review was conducted using Joanna Biggs Institute methodology, and was conducted in Pubmed, Cinahl, Scielo, Ebscohost, Open Grey, Mednar, Worldwidescience, and Science Direct. Inclusion criteria included quantitative, qualitative, or mixed studies as well as systematic reviews and opinion articles, published in Portuguese or English, without publication date limitation, with “adolescents” as the population, “hope” as a concept, and “nursing” as context. Overall studies quality was quite high. The extraction of relevant information from each selected article was summarized in a table that is publicly available at Open Science Framework. Sample: A total of 1259 articles were identified by title and 1220 were excluded by abstract.25 empirical articles met the inclusion criteria. Results: The concept of hope in this population was associated with other concepts such as resilience or well-being. Nursing interventions increase hope with positive outcomes in healthy or with chronic/complex diseases adolescents. Conclusion: Hope is an essential component of nursing care for healthy, with chronic or complex disease adolescents with increased interest in the scientific community. Implications:This review recommends orientations for the nursing process with a central focus in address human responses, nursing interventions, and the results of those interventions.info:eu-repo/semantics/publishedVersio
