Intramuscular sex steroid hormones are associated with skeletal muscle strength and power in women with different hormonal status
2015
International audience; Estrogen (E2)-responsive peripheral tissues, such as skeletal muscle, may suffer from hormone deficiency after menopause potentially contributing to the aging of muscle. However, recently E2 was shown to be synthesized by muscle and its systemic and intramuscular hormone levels are unequal. The objective of the study was to examine the association between intramuscular steroid hormones and muscle characteristics in premenopausal women (n = 8) and in postmenopausal monozygotic twin sister pairs (n = 16 co-twins from eight pairs) discordant for the use of E2-based hormone replacement. Isometric skeletal muscle strength was assessed by measuring knee extension strength.…
The hydrothermal system of the Domuyo volcanic complex (Argentina): A conceptual model based on new geochemical and isotopic evidences
2016
The Domuyo volcanic complex (Neuquén Province, Argentina) hosts one of the most promising geothermal systems of Patagonia, giving rise to thermal manifestations discharging hot and Cl−-rich fluids. This study reports a complete geochemical dataset of gas and water samples collected in three years (2013, 2014 and 2015) from the main fluid discharges of this area. The chemical and isotopic composition (δD-H2O and δ18O-H2O) of waters indicates that rainwater and snow melting are the primary recharge of a hydrothermal reservoir located at relative shallow depth (400–600 m) possibly connected to a second deeper (2–3 km) reservoir. Reactive magmatic gases are completely scrubbed by the hydrotherm…
Comunità resilienti e auto sostenibili. Le politiche urbane dell’agroalimentare in Andalusia
2014
Negli ultimi anni si sono moltiplicati i dibattiti riguardanti la sovranità alimentare. Il sistema agroalimentare, complessa struttura di relazioni ecologiche, sociali ed economiche, ricopre, infatti, un ruolo importante sia per quanto riguarda la forma del territorio, sia per il sostentamento della popolazione. In Andalusia, la maggiore area agricola produttiva spagnola ed europea, si stanno plasmando differenti realtà per lo sviluppo di un sistema agroalimentare alternativo a quello industriale. Questo nuovo sistema, che in questa Comunidad conta già 43 esperienze supportate da produttori, cittadini, amministrazioni e entità scientifiche, oltre ad essere rispettoso dell’ambiente, è capace…
Lo bueno, si breve, dos veces bueno a veces
2007
Los bebedores pueden distribuirse dentro de un continuum, de acuerdo con su nivel de riesgo y problemas. Las intervenciones deberían distribuirse y administrarse también sin solución de continuidad, incluyendo desde la prevención hasta la rehabilitación.La intervención breve es una de las mejores estrategias para reducir la carga morbosa del alcohol; por otra parte, los pacientes dependientes deberían ser tratados con intervenciones amplias y personalizadas con años de seguimiento. Breve y extenso al mismo tiempo, ¿es una contradicción?Se presenta una reflexión en torno a la ampliación de la base del tratamiento y la necesidad de identificar las dimensiones psíquica , física y social dentro…

Internet Related Technologies in the auditing profession: A WOS bibliometric review of the past three decades and conceptual structure mapping
2022
Research on Internet-Related Technologies in the auditing profession has grown substantially over the past three decades; however, it is very fragmented. This study seeks to synthesize and provide a comprehensive overview of the literature. Using bibliometric techniques and content analysis, this study provides an exhaustive overview of the research on Internet-Related Technologies in the auditing profession. The study utilized bibliography from the Web of Science database spanning for three decades from 1990 to 2019. A total of 236 academic documents, written by 478 authors from 102 sources was retrieved and used for the analysis. HistCite and Biblioshiny in R were used to run the citation…
Educar
2015
El presente artículo describe una experiencia de formación en alternancia en un contexto de educación superior; en concreto, a partir de la iniciativa desarrollada por Florida Universitaria, centro adscrito a la Universidad de Valencia. La formación en alternancia implica alternar el aprendizaje entre períodos desarrollados en el centro educativo y momentos desarrollados en el contexto laboral. El objetivo del presente trabajo es identificar una iniciativa que, de forma empírica, muestre cómo estos periodos impactan en el aprendizaje de competencias de los estudiantes. La metodología que se ha aplicado en la experiencia de formación en alternancia se basa en el aprendizaje basado en problem…
Preparation, characterization and catalytic properties of vanadium oxides supported on calcined Mg/Al-hydrotalcite
1995
Abstract Vanadium oxide supported on calcined hydrotalcite has been investigated for the oxidehydrogenation of n-butane in the 500–550°C temperature interval. Hydrotalcite (Mg/Al atomic ratio of 2.77), consisting of a single phase only, has been employed as a support precursor. The vanadium catalysts (0–50, referred as wt.-% V 2 O 5 ) were prepared by impregnation of calcined hydrotalcite (450°C) with ammonium metavanadate (in an aqueous solution) or vanadyl acetylacetonate (in a methanolic solution), and then calcined at 600°C for 4 h. During the impregnation step, the support is transformed into hydrotalcite if aqueous solutions are used. However, it is not modified if methanolic solution…
