Inner and outer star forming regions over the disks of spiral galaxies. I. Sample characterization
Context. The knowledge of abundance distributions is central to understanding
the formation and evolution of galaxies. Most of the relations employed for the
derivation of gas abundances have so far been derived from observations of
outer disk HII regions, despite the known differences between inner and outer
regions. Aims. Using integral field spectroscopy (IFS) observations we aim to
perform a systematic study and comparison of two inner and outer HII regions
samples. The spatial resolution of the IFS, the number of objects and the
homogeneity and coherence of the observations allow a complete characterization
of the main observational properties and differences of the regions. Methods.
We analyzed a sample of 725 inner HII regions and a sample of 671 outer HII
regions, all of them detected and extracted from the observations of a sample
of 263 nearby, isolated, spiral galaxies observed by the CALIFA survey.
Results. We find that inner HII regions show smaller equivalent widths, greater
extinction and luminosities, along with greater values of
[NII]{\lambda}6583/H{\alpha} and [OII]{\lambda}3727/[OIII]{\lambda}5007
emission-line ratios, indicating higher metallicites and lower ionization
parameters. Inner regions have also redder colors and higher photometric and
ionizing masses, although Mion/Mphot is slighty higher for the outer regions.
Conclusions. This work shows important observational differences between inner
and outer HII regions in star forming galaxies not previously studied in
detail. These differences indicate that inner regions have more evolved stellar
populations and are in a later evolution state with respect to outer regions,
which goes in line with the inside-out galaxy formation paradigm.Comment: 16 page
Design of VR app applied to cognitive training
This project pretends to develop a virtual reality application to improve actual treatments for
patients who suffer from a cognitive degenerative disease. This is possible thanks to what this
technology offers to us, and which have had a “boom” in recent years, offering the patient to
have a fully immersion and high sensorial experience. The fact that patient works in a virtual
environment makes them to not be aware of what happens in real world. The required
technology for the development of this application has been offered by “Vysion360” company.
This project is the continuation of several end-of-degree projects in which a virtual application set
in a supermarket has been developed, thanks to “unity” software. This VR application contains
different game modes that allow data collection and to follow patients’ progress. In this project,
the main goal was to reduce application’s weight, as well as improve its performance and make a
more realistic and uniform supermarket. All what is explained before help patient’s immersion
and comfort.
Throughout this project’s memory, all steps done while developing the application has been
explained, as well as the tools we had, the methodology followed, how does each game works, an
explanation on game controls, the improvements made and patients’ assessments.
At last, previous projects had collaboration with Hospital Clínic which allowed the application to
be tested with patients. In this project, the VR app has been tested with several patients from
Associació de Disminuïts Físics d’Osona, and that allowed us to take into account some of their
appreciations to be the future lines that the application has to follow in order to be developed
and optimized
Influence of postweaning feeding management of beef heifers on performance and physiological profiles through rearing and first lactation
The aim of this study was to examine the effects of 2 postweaning feeding management approaches (FEED: 0.8 [HIGH] vs 0.6 [MOD] kg/d target ADG) on the performance of heifers of 2 beef breeds (BREED: Parda de Montaña [PA] vs Pirenaica) calving at 2 yr. Twenty-five heifers previously creep fed before weaning (6 mo) were assigned to 2 planes of nutrition from 6 to 15 mo of age. At 15 mo, they were inseminated, and then received similar diets until weaning of their first calf (4 mo postcalving). Several parameters were measured to analyze growth and development (BW; ADG; size measures at 6 mo, 15 mo, calving, and weaning), performance at puberty and first breeding, and dam and calf performance in the first lactation (calving traits, ADG, milk yield). Metabolic (glucose, cholesterol, NEFA, ß-hydroxybutyrate, and urea) and endocrine status (IGF-I and leptin) were assessed in plasma samples collected every 3 mo from 6 mo to calving and monthly during lactation. No interaction between BREED and FEED was observed. Heifers from the HIGH feeding treatment had higher postweaning ADG than those on the LOW diet. At 15 mo, they had greater BW, heart girth, and external pelvic area, but they did not differ thereafter. All heifers reached puberty at similar BW (55% mature BW) but different ages. Heifers from the HIGH treatment tended (P < 0.09) to be pubertal earlier, and PA heifers were 1.6 mo younger than Pirenaica heifers (P < 0.05) at puberty. At the time of conception (452 ± 59 kg) and calving (471 ± 51 kg), BW was above common recommendations in all groups. Calving traits and performance in lactation did not differ between feeding treatments. BREED only influenced birth weight; PA calves being heavier (P < 0.05), which resulted in a larger calf/cow BW ratio, but no effect on calving difficulty or subsequent performance. Metabolic substrates and hormones depended mostly on sampling date, which was related to current energy and protein intake. Glucose (P < 0.001), cholesterol (P < 0.001), and IGF-I (P < 0.05) were greater during the postweaning phase in heifers on the HIGH diet, and persistent physiological effects were observed during lactation. Age at puberty was negatively related with IGF-I (r = -0.43, P < 0.001), but not with leptin concentrations. In conclusion, regardless of breed, a moderate growth rate ensured adequate heifer development and performance until the first lactation, whereas no advantage was gained from enhanced postweaning gains
Sociedad y patrimonio : políticas públicas
Los nuevos retos que plantea la sociedad del siglo XXI reclaman del patrimonio cultural que ejerza los papeles que le confiere ser tanto un recurso para la cultura como un capital económico. La primera de las funciones está relacionada con la construcción de identidades sociales, con valores simbólicos, con el servicio a la educación y a la ciencia, con el estímulo de la conciencia ciudadana o con los valores sensitivos y de disfrute. Como capital económico, el patrimonio está relacionado con la inserción en el sistema productivo, incluyendo la generación de rentas e incluso de empleo y, particularmente, con la inserción en el tejido local a través de la participación en el desarrollo regional. Ambas posiciones indican que al patrimonio cultural le corresponde un papel en la transformación de la sociedad. Lograr que estas demandas sociales sean canalizadas correctamente y promover la relación entre patrimonio y sociedad es un objetivo de tutela y, por consiguiente, es un trabajo que debe ocupar un espacio significativo en las tareas de gestión de la administración cultural. El III Plan General de Bienes Culturales reflexiona sobre estos retos creando una estrategia de trabajo con líneas prioritarias de actuación para lograr los objetivos propuestos.Els nous reptes que es planteja la societat del segle XXI reclamen del patrimoni cultural que exerceixi els papers que li confereix ser tant un recurs per a la cultura com un capital econòmic. La primera de les funcions està relacionada amb la construcció de les identitats socials, amb valors simbòlics, amb el servei a l'educació i a la ciència, amb l'estímul de la consciència ciutadana o amb els valors sensitius i de gaudi. Com a capital econòmic, el patrimoni està relacionat amb la inserció en el sistema productiu, incloent-hi la generació de rendes o fins i tot de llocs de treball i, particularment, amb la inserció en el teixit local mitjançant la participació en el desenvolupament regional. Totes dues posicions indiquen que al patrimoni cultural li correspon un paper en la transformació de la societat. Assolir que aquestes demandes socials siguin canalitzades correctament i promoure la relació entre patrimoni i societat és un objectiu de tutela i, per tant, és un treball que ha d'ocupar un espai significatiu en les tasques de gestió de l'administració cultural. El III Pla General de Béns Culturals reflexiona sobre aquests reptes creant una estratègia de treball amb línies prioritàries d'actuació per assolir els objectius proposats.The XXI century's society contemplates new challenges which demand that cultural heritage plays the role inherent to its nature as cultural resource and economical engine. The first function is related to the creation of social identities, symbolic values, to the service to education and science, to the encouragement of public awareness or to sensitive values and enjoyment; On the other hand, as an economic capital, heritage is related to the insertion in the production system, including income generation and even employment and, particularly, related to the inclusion on local fabric through its participation in regional development. Both conditions indicate that cultural heritage has a predominant role in the transformation of society. To assure that these social demands are channelled properly and to promote the relationship between heritage and society is a tutelary goal and, therefore, is an issue that shall occupy a significant space in cultural administration's management tasks. The Third General Plan of Cultural Assets reflects on these challenges by creating a work strategy with priority lines of action aimed at achieving the proposed objectives
ANÁLISIS DEL VALOR DE MARCA DE LAS ENTIDADES FINANCIERAS: EL EFECTO HALO Y EL MODELO DE ELECCIÓN DISCRETA
El presente trabajo trata de cuantificar el valor de marca y el posicionamiento de las entidades financieras en dos mercados diferentes: consumidores finales y microempresas. Así mismo, se busca identificar las dimensiones de imagen de mayor peso a la hora de elegir a una entidad como la de mejor valoración global. A través del modelo de elección discreta y del análisis del efecto halo ,se comprueba la importancia del trato personal al cliente como la variable de mayor peso en la elección de marca. Además, se observa la mayor intensidad del efecto halo para las cajas de ahorros en el caso de los consumidores particulares. Sin embargo, en el segmento de microempresas, el valor de marca es superior para los bancos

Conceptual multidimensionality in medical translation
En la comunicación científica, la selección de un término suele conllevar que se resalte una característica más o menos prototípica del concepto, una intención en el emisor o una dimensión del concepto. En la comunicación interlingüística y a menudo intercultural que entraña la traducción en ámbitos biosanitarios, prestar atención a estas dimensiones es importante para que el producto cumpla con las expectativas del receptor meta. El proyecto VARIMED (FFI2011-23120) se plantea estudiar la motivación cognitiva que existe en la selección léxica de distintas formas para dar nombre a conceptos médicos de cara a establecer la presencia de una sistematización en dicha motivación. En este artículo abordaremos estas características desde la descripción de los objetivos del proyecto y la metodología seguida en el mismo.In scientific communication, selecting a term often means highlighting a more or less prototypical feature of a concept, revealing an intention from the issuer or even a certain facet of the concept. It is particularly important to pay due attention to such facets or conceptual dimensions in the process of interlinguistic and intercultural mediation implied by biomedical translation so that the text matches the target audience expectations. The project VariMed (FFI2011-23120) attempts to study the cognitive motivation underlying the lexical selection of different denominative variants for medical concepts in order to find patterns which explain the causes or motivation for terminological variation. This paper deals with the communicative and cognitive motivation from the point of view of the objectives and the methodology followed in VariMed
Inter-rater and intra-rater reliability of the extended TUG test in elderly participants
Background: To analyse the reliability, variance and execution time of the Extended Timed Up and Go (Extended
TUG) test in three age groups of elderly participants (G1: 55–64 years; G2: 65–74 years; G3: 75–85 years).
Methods: An analytical cross-sectional study of 114 recruited participants (63 women) of average age 70.17 (± 7.3) years
was undertaken. Each participant performed the Extended TUG three consecutive times, with a rest break between tests of
120 s. Both the intragroup and intergroup reliability of the measurements in the Extended TUG were analysed.
Results: The reliability of the Extended TUG test is excellent for the first and second decades but drops down to good for
the third decade. Specifically, intragroup reliability ranged from 0.784 for G3 to 0.977 for G1 (G2 = 0.858). Intergroup reliability,
compared with intragroup reliability, was slightly lower, ranging between 0.779 for G3 and 0.972 for G1 (G2 = 0.853).
Conclusion: The reliability of the Extended TUG test progressively decreases with increasing age, being excellent for the
younger age groups and good for the oldest age group
Aplicación de la termografía en el diagnóstico y valoración de la pododermatitis plantar en rapaces
La pododermatitis plantar es una patología de gran importancia en la clínica aviar. Su diagnóstico precoz es vital para un buen pronóstico. Por ello, se ha estudiado la posibilidad de detectarla mediante termografía, técnica que no necesita contacto con el paciente, reduciendo así el estrés que el manejo supone para la mayoría de animales, especialmente los salvajes. Los resultados obtenidos muestran que la termografía permite detectar la pododermatitis plantar antes de la aparición de lesiones, por la mayor diferencia entre las temperaturas máxima y mínima de la planta y por el patrón térmico.Plantar pododermatitis is great important pathology in avian medicine. Its early diagnosis allows a good prognosis. Therefore, the application of thermography to detect bumblefoot has been studied. This technique requires no contact with the patient, reducing the stress, very important in wildlife. Results show thermography is a useful tool for detecting plantar pododermatitis, even before the appearance of lesions, for the major difference between the maximum and minimum temperature of the plant and its thermal pattern
