The role of Mediterranean wetlands in climate regulation and greenhouse gases exchanges: from carbon biogeochemistry to European water and nature Dir…
2022
Atesa la seua alta activitat biogeoquímica, els aiguamolls són un dels tipus d'ecosistemes més actius en el cicle global del carboni, amb altes taxes d'intercanvi de carboni i de gasos d'efecte hivernacle (GEH), i, per tant, un gran potencial de regulació climàtica. Una de les parts més importants de la biogeoquímica del carboni als aiguamolls està lligada a les taxes metabòliques, a partir del coneixement de les quals es pot determinar un balanç de carboni associat amb el potencial intercanvi de carboni amb l'atmosfera. La seua capacitat per retindre carboni i mitigar el canvi climàtic, o, per contra, d'alliberar més GEH, i contribuir a l'escalfament global, es determina pel balanç de carb…
Latinoamérica según Latinoamérica
2019
espanolPartiendo de una observacion sobre el escenario actual que protagoniza Latinoamerica, en contraste con su pasado, el escrito intenta exponer la trascendencia que alcanzan los imaginarios sociales en la construccion de la identidad cultural, y como durante decadas estos imaginarios fueron vulnerados por la intervencion de modelos ajenos. En igual sentido, el abordaje revela las derivaciones del indivisible vinculo entre los medios de comunicacion y los imaginarios sociales, que retumban en la proyeccion de arquetipos y relatos de mundos posibles para la region. EnglishBased on an observation on the current scene starring Latin America, in contrast to its past, the article tries to exp…
The Diterpenoids of the Genus Marrubium (Lamiaceae)
2006
The occurrence and chemical structures of labdane diterpenoids from the genus Marrubium are reviewed and the published 13C NMR spectroscopic data for these compounds is presented. The pharmacological activities and biogenesis of these diterpenoids are also reported.
La educación de los profesionales del cine: características y tensiones de un campo en formación
2019
La enseñanza del cine ha adquirido ya un lugar dentro del campo de la educación superior: las licenciaturas en Realización de Cine y TV, el Diseño de Imagen y Sonido conviven, no sin tensiones, con las ya institucionalizadas carreras de Comunicación Social. Dentro del campo de los estudios sobre cine, la enseñanza no ha sido un tópico especialmente abordado, el presente artículo busca aproximarse a esta temática a partir de trazar una historia de la educación cinematográfica en el país que permita identificar continuidades y rupturas, y comprender, en base a la inscripción socio-histórica de este proceso, las resignificaciones ligadas a la enseñanza del cine siendo que es en esa trama donde…
Comparative experimental analysis on the compressive behaviour of masonry columns strengthened by FRP, BFRCM or steel wires
2017
Abstract In the last decade, several studies have investigated the application of Fibre Reinforced Polymer (FRP) wraps to masonry piers in order to provide a confinement effect and enhance compressive strength and ductility. Although this technique has proved to be quite effective, various drawbacks arise when organic resins are used to bind fibres. To solve these problems, different techniques have been developed to be used as alternative methods for enhancing the structural performances of weak masonry columns. Among these, the use of Basalt Fibre Reinforced Cementitious Matrix (BFRCM) wrapping, or the application of steel wires at mortar joints. This paper presents the results of an expe…
Homozygous familial hypobetalipoproteinemia: two novel mutations in the splicing sites of apolipoprotein B gene and review of the literature.
2015
Objective: Familial hypobetalipoproteinemia (FHBL) is autosomal codominant disorder of lipoprotein metabolism characterized by low plasma levels of total cholesterol (TC), low-density lipoproteincholesterol (LDL-C) and apolipoprotein B (apoB) below the 5 th percentile of the distribution in the population. Patients with the clinical diagnosis of homozygous FHBL (Ho-FHBL) are extremely rare and few patients have been characterized at the molecular level. Here we report the medical history and the molecular characterization of one paediatric patient with clinical features of Ho-FHBL. Methods: A one month old infant with failure to thrive, severe hypocholesterolemia and acanthocytosis was clin…
An Adaptive Alternating Direction Method of Multipliers
2021
AbstractThe alternating direction method of multipliers (ADMM) is a powerful splitting algorithm for linearly constrained convex optimization problems. In view of its popularity and applicability, a growing attention is drawn toward the ADMM in nonconvex settings. Recent studies of minimization problems for nonconvex functions include various combinations of assumptions on the objective function including, in particular, a Lipschitz gradient assumption. We consider the case where the objective is the sum of a strongly convex function and a weakly convex function. To this end, we present and study an adaptive version of the ADMM which incorporates generalized notions of convexity and penalty…
Valencia Model of Waking Hypnosis: Background, Research, and Clinical Applications
2018
The goal of this article is to provide a comprehensive review of the historical background, methods, and clinical applications of the Valencia Model of Waking Hypnosis (VMWH). The active-alert-waking methods have been developed and used since the 19th century as an alternative when the suggestions for relaxation and drowsiness were not helpful for specific cases, or when the person needed to use hypnotic suggestions in situations that required them to be alert and with their eyes open (i.e. in vivo exposure, sports performance, academic work, etc.). In most of these methods, the hypnotized person keeps their eyes open, and the suggestions given are for alertness, focused attention, mind exp…
Awareness and understanding of cancer immunotherapy in Europe.
2014
3053 Background: Use of immunotherapies in the treatment of cancer is growing and a range of new immunotherapeutic strategies are being evaluated. It is important that healthcare providers (HCP) understand these treatments and how they compare with and may complement established therapies. As part of the activities of the POINT expert group, we commissioned a survey of current awareness, attitudes and perceptions of cancer immunotherapy in Europe. Methods: From August-September 2011, 426 healthcare professionals (HCPs: oncologists, surgeons and oncology nurses) from France, Germany, Italy, Spain and the UK (~85 respondents/country) completed online interviews. Representatives of patient ad…
