    Después de una breve introducción sobre la importancia del álamo tanto para el medio ambiente como para la industrial de la madera, se analizarán los usos más comunes de la madera de chopo, en particular la producción de chapas, que es el mas importante y rentable destino para la materia prima de mejor calidad, resultado del cultivo intensivo delchopo. La madera contrachapada puede ser considerado un producto "maduro" tanto en términos de desarrollo (niveles de eficacia, producciones como productividad) y de mercado (en este momento el chapeado, también sufre de la competencia de las nuevas clases de paneles). Desde un punto de vista técnico, las posibles innovaciones están relacionadas estrictamente con la capacidad de encontrar nuevos usos y productos, con un mayor valor añadido. En este marco, el sector de la construcción parece ofrecer nuevas posibilidades, gracias al interés renovado por la madera y productos derivados de la madera. Otro destino posible para la madera de chopo podría ser la producción de madera laminada encolada. En Italia se ralizó una investigación bastante completa sobre este tema, que incluyó la posibilidad del chopo mezclado con otra especie (en particular eucalipto y alerce). Se adjuntan detalles de los resultados obtenidos. En el sector de la construcción, más allá de la posibilidad de usar el contrachapado producido para este fin, la madera de chopo también podría ser una materia prima muy buena para la producción "de paneles tecnológicos" (LVL, OSB). Para concluir, la madera de chopo es seguramente conveniente también para el uso en otros sectores. La fiabilidad de productos (con propiedades mejoradas, si fuera necesario) y sus características ecológicas, juntos con la preparación de información técnica actualizada, son, en cualquier caso, algunos de los principales factores que pueden garantizar un aumento del empleo de madera de chopo en usos no tradicionales.________________________________After a brief introduction on the importance of poplar for both the environment and the woodindustry system, the current common uses of poplar wood are discussed, with particular reference to the production of plywood, which is by far the most important and remunerative destination for the best raw material resulting from intensive poplar cultivation. Plywood can be considered a “mature” product both in terms of development (efficiency levels, yields and productivity) and of market (at the moment plywood is also suffering from the competition of new kinds of panels). From a technical point of view, possible innovations are strictly related to the ability to find new uses and new products, possibly with value added figures. In this frame, the building sector seems to offer new possibilities, also thanks to the renewed interest for wood and wood-based products. Another possible destination for poplar wood could be the production of glue-laminated timber. A quite complete research was done in Italy on this subject, which included the possibility of mixing poplar with other species (in particular eucalypt and larch). Details are given on the results obtained. In the building sector, beyond the possibility of using purposely-produced plywood, Poplar wood could also be a very good raw-material for the production of “engineered panels” (LVL, OSB). In conclusion, poplar wood is surely suitable also for use in other sectors. The reliability of products (with improved properties, if necessary) and their ecological characteristics, together with the preparation of updated technical information, are, in any case, among the main factors that can guarantee an increase of the use of poplar wood in nontraditional applications

    Interface reconstruction in superconducting CaCuO2/SrTiO3 superlattices: A hard x-ray photoelectron spectroscopy study

    Full text link
    Here we report about the interface reconstruction in the recently discovered superconducting artificial superlattices based on insulating CaCuO2 and SrTiO3 blocks. Hard x-ray photoelectron spectroscopy shows that the valence bands alignment prevents any electronic reconstruction by direct charge transfer between the two blocks. We demonstrate that the electrostatic built-in potential is suppressed by oxygen redistribution in the alkaline earth interface planes. By using highly oxidizing growth conditions, the oxygen coordination in the reconstructed interfaces may be increased, resulting in the hole doping of the cuprate block and thus in the appearance of superconductivity.Comment: 9 pages, 6 figure

    Defining a roadmap for harmonizing quality indicators in Laboratory Medicine: A consensus statement on behalf of the IFCC Working Group "laboratory Error and Patient Safety" and EFLM Task and Finish Group "performance specifications for the extra-analytical phases"

    The improving quality of laboratory testing requires a deep understanding of the many vulnerable steps involved in the total examination process (TEP), along with the identification of a hierarchy of risks and challenges that need to be addressed. From this perspective, the Working Group \u201cLaboratory Errors and Patient Safety\u201d (WG-LEPS) of International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) is focusing its activity on implementation of an efficient tool for obtaining meaningful information on the risk of errors developing throughout the TEP, and for establishing reliable information about error frequencies and their distribution. More recently, the European Federation of Clinical Chemistry and Laboratory Medicine (EFLM) has created the Task and Finish Group \u201cPerformance specifications for the extraanalytical phases\u201d (TFG-PSEP) for defining performance specifications for extra-analytical phases. Both the IFCC and EFLM groups are working to provide laboratories with a system to evaluate their performances and recognize the critical aspects where improvement actions are needed. A Consensus Conference was organized in Padova, Italy, in 2016 in order to bring together all the experts and interested parties to achieve a consensus for effective harmonization of quality indicators (QIs). A general agreement was achieved and the main outcomes have been the release of a new version of model of quality indicators (MQI), the approval of a criterion for establishing performance specifications and the definition of the type of information that should be provided within the report to the clinical laboratories participating to the QIs project

    Experimental investigation of non-linear wave to plasma interaction in a quasi-flat magnetostatic field

    Get PDF
    A characterization of wave-to-plasma interaction in a quasi-flat magnetostatic field at 3.75 GHz has been carried out by using a small-wire movable RF antenna, connected to a spectrum analyzer. The coupling between electromagnetic and electrostatic waves leads to a characteristic spectral emission in low frequency range and around the pumping wave frequency. The most relevant results consist in the broadening of the pumping wave spectrum above critical RF power thresholds and in the generation of sidebands of the pumping frequency, with corresponding components in low frequency domain. The non-linearities are accompanied by the generation of overdense plasmas and intense fluxes of X-rays

    La presente investigación tuvo como objetivo principal determinar la influencia de la gestión del talento humano en el compromiso organizacional y la satisfacción laboral de los trabajadores del Centro de Salud Mental Comunitario (CSMC) Santiago en el año 2022. Se desarrolló una investigación de tipo básica por su propósito, cuantitativa por el paradigma, no experimental por el tipo de diseño que adoptó, explicativa por su profundidad, y transversal por su temporalidad. La población estuvo constituida por los trabajadores en número de 42, coincidiendo la misma con una muestra de estudio, a quienes se les aplicó tres instrumentos de recolección de datos como son cuestionarios sobre gestión del talento humano, cuestionario sobre compromiso organizacional y cuestionario sobre satisfacción laboral. Los resultados de la investigación permitieron concluir que la gestión del talento humano influye de manera significativa en el compromiso organizacional y la satisfacción laboral, afirmación que se deduce a partir de la aplicación del modelo de regresión logística ordinal, en el que se obtuvo un ajuste adecuado del modelo y coeficientes Pseudo R cuadrado de Nagelkerke iguales a 0.822 y 0.938, respectivamente; lo cual muestra que la variabilidad del compromiso organizacional y la satisfacción laboral pueden ser explicadas por la gestión del talento humano en los trabajadores del centro de salud mental comunitario de Santiago en el año 2022
