La vecindad civil como requisito del testamento mancomunado aragonés.

En este trabajo se expone la naturaleza y requisitos del testamento mancomunado, prestando especial atención al testamento mancomunado aragonés, y además, la regulación del mismo en el Código Civil y en el resto de ordenamientos del territorio español. Posteriormente, se trata de manera más concreta el tema de la vecindad civil, los cambios que pueden producirse en esta circunstancia de la persona, y los problemas con los que podemos encontrarnos para testar de forma mancomunada, porque como se explica más detalladamente, no todos los españoles pueden testar de mancomún, sino sólo aquellos que lo tengan permitido por su ley personal, y ésta, es determinada por la vecindad civil

A Deep Learning-Based System (Microscan) for the Identification of Pollen Development Stages and Its Application to Obtaining Doubled Haploid Lines in Eggplant

[EN] The development of double haploids (DHs) is a straightforward path for obtaining pure lines but has multiple bottlenecks. Among them is the determination of the optimal stage of pollen induction for androgenesis. In this work, we developed Microscan, a deep learning-based system for the detection and recognition of the stages of pollen development. In a first experiment, the algorithm was developed adapting the RetinaNet predictive model using microspores of different eggplant accessions as samples. A mean average precision of 86.30% was obtained. In a second experiment, the anther range to be cultivated in vitro was determined in three eggplant genotypes by applying the Microscan system. Subsequently, they were cultivated following two different androgenesis protocols (Cb and E6). The response was only observed in the anther size range predicted by Microscan, obtaining the best results with the E6 protocol. The plants obtained were characterized by flow cytometry and with the Single Primer Enrichment Technology high-throughput genotyping platform, obtaining a high rate of confirmed haploid and double haploid plants. Microscan has been revealed as a tool for the high-throughput efficient analysis of microspore samples, as it has been exemplified in eggplant by providing an increase in the yield of DHs production.This research was funded by the Spanish Ministerio de Ciencia, Innovacion y Universidades, Agencia Estatal de Investigacion and Fondo Europeo de Desarrollo Regional (grant RTI-2018-094592-B-I00 from MCIU/AEI/FEDER, UE). This work was also undertaken as part of the initiative "Adapting Agriculture to Climate Change: Collecting, Protecting and Preparing Crop Wild Relatives", which is supported by the Government of Norway. The project is managed by the Global Crop Diversity Trust with the Millennium Seed Bank of the Royal Botanic Gardens, Kew, and implemented in partnership with national and international gene banks and plant breeding institutes around the world.

Development of environmentally friendly composite matrices from epoxidized cottonseed oil

The continuous rise in oil prices has led to the use of other ways to obtain polymer materials. This paper proposes a methodology to obtain a thermosetting resin from cottonseed oil by epoxidation process. The cottonseed oil contains as most representative fatty acids: 52.5% of linoleic acid (C18: 2), 23.9% of palmitic acid (C16: 0) and 17.6% of oleic acid (C18: 1); the real iodine index, which is indicative of the number of double bonds, has a value of 107. Epoxidized cottonseed oil (ECSO) has been successfully obtained using conventional epoxidation process with hydrogen peroxide, acetic acid and sulfuric acid, maintaining a constant temperature of 70 °C with homogeneous magnetic stirring. Average oxirane oxygen content (OOC) of 5.32% can be obtained by conventional epoxidation process which represents a yield over 83%. The epoxidized oil has been crosslinked with mixtures of two cyclic anhydrides to tailor different properties on final crosslinked thermosetting resins: on the one hand, methyl nadic anhydride (MNA) which is characterized by a rigid molecular structure and on the other hand, dodecenylsuccinic anhydride (DDSA) with a long side chain that can confer flexibility. The crosslinking process has been followed by dynamic differential scanning calorimetry (DSC), ionic mobility and oscillatory rheometry (OR) as well as gel time determination. The effect of the hardener mixture (wt.% DDSA:MNA) on mechanical performance of cured materials has been followed by flexural and impact tests as well as the evolution of the storage modulus (G′) by dynamic mechanical analysis (DMA) in torsion mode. By selecting the appropriate hardener mixture, it is possible to obtain crosslinked materials with different properties ranging from stiff matrices for ECSO crosslinked with MNA to flexible matrices for ECSO cured with DDSA. This has occurred with other thermosetting resins like epoxidized soy bean oil (ESBO) or epoxidized linseed oil (ELO). (C) 2014 Elsevier Ltd.

Ethnography as a linking method between psychology and sociology: research design

World Conference on Psychology and Sociology 2012CC BY-NC-ND[EN] Ethnography is one of the most relevant methods in qualitative research, and both psychology and sociology use qualitative methods in their research. This is essential when the purpose is to keep the historical memory of different population in relation to facts or experiences from the past. In a first phase, ethnography could expedite study's variables description. Based on the implication of the variable's conceptualization obtained by this first qualitative phase (ethnographic), in subsequent phases of the research, researchers might deepen in the concepts still using descriptive methodology but quantitative, which is typical of both psychology and sociology, for instance, in the quiz methodology. The aim of this study is to show how ethnography can be a relevant method in both psychological and sociologic research when they interact to explain facts and experiences from the past.To illustrate this thought, a study on women who practiced sport in the Spanish dictatorship period (1936-1975) would be shown to explain the variable determination through ethnography methods as life story and in-depth interview. Twenty four Spanish women who practiced sport (in different regions, from different socioeconomic levels, either rural or urban residence and between leisure and competitive sport level) were interviewed to accomplish information about their personal and sport life. This material was ethnographic analyzed to categorize it into five dimensions which explain part of the women experiences in that convulsed period. The categories or dimensions derived were aesthetics, culture, nutrition, community and morality, and showed agreements and disagreements in their perception reflecting a complex women world where sport was a liberating activity as well as a relevant experience which has traced in their personalities and has not only influenced them, but also their progeny life

Sportsmanship rating scale in tennis competition with young players

World Conference on Psychology and Sociology 2012CC BY-NC-ND[EN] This study presents the psychometric properties of a rating scale of sportsmanship in tennis competitions with young players. A total of 446 players used this scale to asses the games they played during a season (n=223). Analyses confirmed the discriminative capacity both sportsmanship(12)and unsportsmanlike(17)items, and high internal consistency of the overall scale (Cronbach's Alpha = 0,702). Moreover, the analysis made to assess the quality of sportsmanship in several tennis championships shows the scores associated with sportmanship and unsportsmanlike behavior and identify the players with the highest scores and lowest in sportiness, allowing the implementation of preventive actions

Conocimiento de la higiene de manos en estudiantes de enfermería

Nursing students’ hands can be the vector of nosocomial infection. Improving knowledge about hand hygiene (HM) reduces nosocomial infection. This is the reason we must know the degree of adherence to hand washing protocol (LM) by nursing studentsFor this purpose, a WHO structured questionnaire for health professionals was done before and after putting a training workshop into practice.A total of 63 students from two nursing degree courses of UEX have participated in the study, with female sector predominance 76.2% (48) and 23.8% (15) for the male. Very significant data were obtained (p <0.015) in the questionnaire P9a (0.012), P9B (0,000) P10 (0,000) P11 and (0.005), P11f (0.002).Students have a moderate knowledge about HM. The study shows the need to improve existing HM training programs, to address gaps in knowledge and to obtain highly qualified nurses in the futureLas manos de los estudiantes de enfermería pueden ser el vector de la infección nosocomial. La mejora en el conocimiento sobre la higiene de manos (HM) reduce la infección nosocomial. Para ello debemos conocer el grado de adherencia al protocolo de lavado de manos (LM) por parte de los alumnos de enfermeríaPara ello se pasó un cuestionario estructurado de la OMS para profesionales de salud, antes y después de llevar a cabo un taller formativo. Han participado en el Estudio un total de 63 alumnos de dos cursos de grado en enfermería de la Universidad de Extremadura (UEX), con una predominancia del sector femenino en 76,2 % (48) y 23,8 % (15) para el masculino.Se obtuvo datos muy significativos (p<0,015) en el cuestionario en P9a (0,012), P9b (0,000), P10 (0,000), P11 e (0,005), P11f  (0,002). Los estudiantes tienen un conocimiento moderado sobre HM. El estudio muestra la necesidad de seguir mejorando los programas de formación de HM existentes, para hacer frente a las lagunas en los conocimientos y obtener unos enfermeros altamente cualificados en el futuro

Mecanismo portador articulado para equipos de clasificación

Número de publicación: ES2409229 A1 (25.06.2013) También publicado como: ES2409229 B1 (24.04.2014) Número de Solicitud: Consulta de Expedientes OEPM (C.E.O.) P201300031 (21.12.2012)Mecanismo portador articulado para equipos de clasificación. El sistema propuesto tiene por objeto proporcionar un mecanismo portante de objetos de forma individualizada para equipos de clasificación por peso e indicadores externos, como el tamaño, color, defectos superficiales, etc. Dispone de dos conjuntos de elementos que se van alternando en la cadena de clasificación: el sistema de giro y el sistema de pesado/vaciado. El sistema de giro es el encargado de hacer rotar los objetos en la zona dotada de los medios para la toma de imágenes. Está formado por parejas de elementos rodantes unidos a un eje que bascula lateralmente. Los objetos se alojan en el hueco definido por cada dos ejes consecutivos, de tal manera que apoyan en cuatro elementos rodantes. Una vez que se han tomado las imágenes el eje que soporta los elementos rodantes bascula y deposita el objeto a clasificar sobre el mecanismo de pesado/vaciado.Universidad de Almerí

The IHG index for hydromorphological quality assessment of rivers and streams : updated version

An updated version of the IHG index is presented. The index is based on three appraisal parameters: 1) the functional quality of the fluvial system, including a) flow regime naturalness, b) sediment supply and mobility, and c) floodplain functionality; 2) the channel quality, including a) channel morphology and planform naturalness, b) riverbed continuity and naturalness of the longitudinal and vertical processes, and c) riverbank naturalness and lateral mobility; and 3) the riparian corridor quality, including a) longitudinal continuity, b) riparian corridor width, and c) structure, naturalness and cross-sectional connectivity.Se presenta una versión actualizada del índice IHG, que se estructura en tres grupos de parámetros: 1) calidad funcional del sistema fluvial, incluyendo a) naturalidad del régimen de caudal, b) disponibilidad y movilidad de sedimentos y c) funcionalidad de la llanura de inundación; 2) calidad del cauce, incluyendo a) naturalidad del trazado y de la morfología en planta, b) continuidad y naturalidad del lecho y de los procesos longitudinales y verticales y c) naturalidad de las m'argenes y de la movilidad lateral; y 3) calidad de las riberas, incluyendo a) continuidad longitudinal, b) anchura y c) estructura, naturalidad y conectividad transversal
