Compositos elaborados con resina de reciclo y fibras de desecho: propiedades mecánicas y evaluación de la constante dieléctrica

Se presentan los efectos de la radiación gamma en las propiedades fisicoquímicas y dieléctricas de materiales compuestos de resina de poliéster de desecho y de celulosa de reciclo de envases de Tetra Pak. Se modifican las propiedades fisicoquímicas de resina poliéster de desecho y de la celulosa de reciclo de envases de Tetra Pak, con lo cual es posible obtener un material compuesto con incremento en las propiedades mecánicas y estudio de la constante dieléctrica

Model-based Optimization of Compressive Antennas for High-Sensing-Capacity Applications

This paper presents a novel, model-based compressive antenna design method for high sensing capacity imaging applications. Given a set of design constraints, the method maximizes the sensing capacity of the compressive antenna by varying the constitutive properties of scatterers distributed along the antenna. Preliminary 2D design results demonstrate the new method's ability to produce antenna configurations with enhanced imaging capabilities

Competitiveness and growth in EMU: The role of the external sector in the adjustment of the Spanish economy

This paper assesses the relevance of the competitiveness argument in the debate on the current situation of the Spanish economy. We estimate error-correction models for exports and imports. Econometric analyses suggest that external demand and domestic activity are the more important determinants of net exports in the long run. However, where competitiveness is concerned, its impact on export growth in the short run appears to be higher than in the longer term. Moreover, during major downturns, the recovery of the Spanish economy has systematically been led by exports, which, in turn, has been associated with strong and rapid competitiveness gains, brought about by competitive devaluations. Since the exchange-rate instrument is not available anymore at national level, there is a case to assess the respective role of fiscal and structural policies in underpinning the recovery of the Spanish economy at the current juncture. The paper concludes that the room for manoeuvre for fiscal-policy stabilisation is currently very limited. In contrast, reducing the weight of distortionary taxes and/or increasing the weight of productive expenditures in a budget-neutral way would have positive impacts on potential growth. Boosting net-export growth crucially depends on the implementation of a comprehensive reform programme, within the framework of a broad social agreement, aiming at recovering competitiveness throughout enhancing competition, improving the functioning of labour and product markets, including the housing rental market, increasing physical, human and knowledge capital accumulation, promoting wage moderation and avoiding price-wage spirals. A pro-active role of the Spanish government in the social dialogue would provide guidance in the process and promote the agreementEMU, Spain, external imbalances, competitiveness, Martinez-Mongay, Maza Lasierra

Gobierno local abierto: diagnóstico en México y Oaxaca

Con un enfoque centrado en el ciudadano y el uso de las tecnologías de la información y la comunicación, la expresión gobierno abierto ha revolucionado la administración pública. Esto ha implicado una alta deliberación, colaboración, participación y publicidad. El objetivo del presente artículo es diagnosticar los estados cuyos municipios siguen el proyecto de gobierno abierto, para lo cual se tomó como muestra a los estados de México y Oaxaca, donde se compararon los estratos de desarrollo humano muy alto y bajo. A partir de ello se formuló la hipótesis de que los gobiernos locales en México responden de forma diferente a la expresión gobierno abierto cuando este tiene que ver de manera directa y proporcional con el desarrollo humano. Es decir, los municipios con mayor desarrollo humano tuvieron también mayor nivel de gobierno abierto, mientras que los gobiernos con menor desarrollo humano alcanzaron niveles inferiores de gobierno abierto. Se estudiaron 30 municipios de ambas entidades, con diez variables a analizar mediante contraste estadístico de chi cuadrada y coeficiente de correlación r de Pearson. Los resultados demostraron que sí existe una relación entre desarrollo humano y gobierno abierto

Clinical Trials of Repurposed Antivirals for SARS-CoV-2

The coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has prompted the repurposing of drugs on the basis of promising in vitro and therapeutic results with other human coronavirus diseases, such as severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS). These repurposed drugs have mainly included remdesivir, favipiravir, lopinavir-ritonavir, ribavirin, interferons, and hydroxychloroquine.

These repurposed drugs have mainly included remdesivir, favipiravir, lopinavir-ritonavir, ribavirin, interferons, and hydroxychloroquine. Unfortunately, the first open-label, randomized, controlled trials are showing poor efficacy of these repurposed drugs. These results highlight the necessity of identifying and characterizing specific and potent SARS-CoV-2 antivirals
