Perceived emotional intelligence as a predictor of depressive symptoms after a one year follow-up during adolescence

Research to date has identified various risk factors in the emergence of depressive disorders in adolescence. There are very few studies, however, which have analyzed the role of perceived emotional intelligence in depressive symptoms longitudinally during adolescence. This work aimed to analyze longitudinal relationships between perceived emotional intelligence and depressive symptoms in adolescence, developing an explanatory model of depression following a one-year follow-up. A longitudinal study was carried out with two waves separated by one year, with a sample of 714 Spanish adolescents. The instruments consisted of self-report measures of depressive symptoms and perceived emotional intelligence. Results underlined gender differences in depressive symptoms and emotional intelligence, and indicated that greater emotional intelligence was associated with a lower presence of depressive symptoms after a one year follow-up. A multiple partial mediation model was developed to explain longitudinally depressive symptoms based on perceived emotional intelligence skills and depressive symptoms. These contributions underscore the need to design programs to prevent depression in adolescence through the promotion of emotional intelligence.peer-reviewe

Una nueva variante anfórica de la Hispania Citerior: La Pascual 1 Parva

Presentamos una variante de una producción anfórica ya conocida, la Pascual 1, a partir de ejemplares ya publicados, si bien hasta ahora no se había puesto de relieve su especificidad. Estos materiales nos permiten documentar una nueva variante anfórica, que proponemos denominar Pascual 1 parva, y que al parecer, se producía en diversos alfares cercanos a la desembocadura del Ebro y en, al menos, dos figlinae del NE de la Hispania Citerior.In this paper, we present a variant of an already known (from published copies) Pascual 1 amphorae, although its specificity has not been emphasized yet. These materials allow us to document a new amphoric variant, which we propose to call Pascual 1 parva, which apparently was produced in various kilns near the mouth of the Ebro river, and, at least, two kilns in the NE of Hispania Citerior

Implementació d'una xarxa can per a la sincronització i diagnòstic de fallades dels inversors d'un Motor Lineal de Reluctància

Aquest treball consisteix en la implementació de una xarxa CAN (Controlled Area Network) per interconnectar 2 inversors corresponents a 2 motors lineals i un circuit de control central encarregat de coordinar les accions, veri car falles, enviar dades dels motor i rebre ordres via Bluetooth des de un dispositiu extern (mòbil o PC). Els inversors van ser desenvolupats per l'autor per al projecte Tren Electromagnètic (Telmag) en l'any 2006, llavors es va desenvolupar la aplicació per controlar els motors però sense comunicació entre els motors ni comunicació externa. Per desenvolupar aquest projecte es faran servir els esmentats inversors, basats en comportes IGBTs, comandades per un microcontrolador dsPIC 30F4011 i sensors de posició inductius. El projecte Telmag, consisteix en un desenvolupament tecnològic de 40 anys d'investigació, que consisteix en la recerca de un sistema de tracció lineal amb un baix cost de construcció de la via, baix costos de manteniment, amb una gran capacitat de tracció que permeti superar fortes pendents i que sigui impossible el seu descarrilament

The prostate cancer-associated human retrovirus XMRV lacks direct transforming activity but can induce low rates of transformation in cultured cells.

The human retrovirus XMRV (xenotropic murine leukemia virus-related virus) is associated with prostate cancer, but a causal relationship has not been established. Here, we have used cultured fibroblast and epithelial cell lines to test the hypothesis that XMRV might have direct transforming activity but found only rare transformation events, suggestive of indirect transformation, even when the target cells expressed the human Xpr1 cell entry receptor for XMRV. Characterization of cells from three transformed foci showed that all were infected with and produced XMRV, and one produced a highly active transforming virus, presumably generated by recombination between XMRV and host cell nucleic acids. Given the sequence similarity of XMRV to mink cell focus-forming (MCF) viruses and the enhanced leukemogenic activity of the latter, we tested XMRV for related MCF-like cytopathic activities in cultured mink cells but found none. These results indicate that XMRV has no direct transforming activity but can activate endogenous oncogenes, resulting in cell transformation. As part of these experiments, we show that XMRV can infect and be produced at a high titer from human HT-1080 fibrosarcoma cells that express TRIM5alpha (Ref1), showing that XMRV is resistant to TRIM5alpha restriction. In addition, XMRV poorly infects NIH 3T3 cells expressing human Xpr1 but relatively efficiently infects BALB 3T3 cells expressing human Xpr1, showing that XMRV is a B-tropic virus and that its infectivity is regulated by the Fv1 mouse locus

Comportamiento productivo de Tithonia diversifolia en bancos forrajeros, bajo condiciones de suelos de Piedemonte Llanero

El objetivo de esta investigación fue evaluar la producción y calidad nutricional de Tithonia diversifolia y sus fracciones (hojas y tallos) en un sistema de banco forrajero. Este estudio se llevó a cabo en la finca San miguel, municipio de Paratebueno, Cundinamarca, a 526 m de altitud y temperatura promedio de 27°C. Se evaluaron tres parcelas homogéneas con 400 arbustos cada una, la distancia entre arbustos fue de 1m y entre surcos de 0,75m para obtener una densidad de siembra de 12500 plantas/ha. Se realizó cuatro muestreos con intervalos de 45 días, En cada muestreo fueron cosechados 13 arbustos al azar por parcela. Se calculó la producción de forraje verde y se evaluó materia seca (MS), proteína cruda (PC), Digestibilidad In Vitro de la materia seca (DIVMS), fibra en detergente neutro (FDN) y fibra en detergente ácido (FDA) para estimar la calidad nutricional de la planta completa y sus fracciones. Se empleó estadística descriptiva para las variables evaluadas, utilizando el software Infostat®. Se encontró una producción de biomasa de 107,6 t/ha/año en forraje verde y 24,6 t/ha/año en MS. La planta completa presentó un contenido de PC de 19,5%, una DIVMS de 57,6%, FDN de 58,8% y FDA de 42,2%. La relación hoja-tallo fue de 1,8:1 siendo las hojas la fracción con mayor proporción. La mortalidad de plantas fue de 1,62% durante los cuatro cortes realizados. Según los resultados obtenidos en esta investigación T. diversifolia se adapta a las condiciones de piedemonte llanero con aceptable producción y calidad forrajera, convirtiéndose en una alternativa nutricional para los productores de la región
