Economic evaluation of bio-based supply chains with CO2 capture and utilisation
Carbon capture and storage (CCS) and carbon capture and utilisation (CCU) are acknowledged as important R&D priorities to achieve environmental goals set for next decades. This work studies biomass-based energy supply chains with CO2 capture and utilisation. The problem is formulated as a mixed-integer linear program. This study presents a flexible supply chain superstructure to answer issues on economic and environmental benefits achievable by integrating biomass-coal plants, CO2 capture and utilisation plants; i.e. location of intermediate steps, fraction of CO2 emissions captured per plant, CO2 utilisation plants' size, among others. Moreover, eventual incentives and environmental revenues will be discussed to make an economically feasible project. A large-size case study located in Spain will be presented to highlight the proposed approach. Two key scenarios are envisaged: (i) Biomass, capture or utilisation of CO2 are not contemplated; (ii) Biomass, capture and CO2 utilisation are all considered. Finally, concluding remarks are drawn.Peer ReviewedPostprint (author's final draft
Copias de copias: la apropiación de la apropiación en Arte Contemporáneo
Resumen Este artículo estudia la apropiación como repetición y copia. Propone un análisis del Apropiacionismo desde dos enfoques: la desviación de significados debida a cambios de temporalidad de la obra y su contexto, y la desviación generada con la aparición de la conectividad global gracias a la web 2.0, y a la materialización del Arte Digital. El artículo propone, en primer lugar, un análisis temporal de la obra After Walker Evans de Sherrie Levine, como forma de apropiación clásica derivada de la desviación contextual. En segundo, un acercamiento al mundo del Arte Digital para analizar la apropiación de la apropiación, copias de copias, como forma de remediación basada en el concepto de “Arte como bien común” y su enfoque hacia la materialización del Arte Digital. Para ello serán estudiadas las obras aftersherrielevine.com y Printwikipedia de Michael Mandiberg y Street Ghost y Overexposed Series de Paolo Cirio.Abstract This article studies appropriation as a form of repetition and copy. The text proposes an analysis of Appropriationism from two points of view: the deviation of meanings derived from changes on the temporality of the work and its context, the deviation generated by the appearance of global connectivity thanks to Web 2.0, and by the materialization of Digital Art. The article proposes, firstly, a temporal analysis of Sherrie Levine’s work After Walker Evans as a form of classic appropriation derived from the contextual deviation. Secondly, an approach to Digital Art to analyse the appropriation of appropriation, copy of copy, as a form of remediation based on the concept of "Art as a common good" and its focus on the materialization of Digital Art. Michael Mandiberg’s works Aftersherrielevine. com and Printwikipedia and Paolo Cirio’s works Street Ghost and Overexposed Series will be set to study
Influencia de los factores epidemiológicos y socioeconómicos en la evolución de la infección VIH.
Introducción: Existe la percepción por parte de los facultativos que tratan a pacientes VIH de la existencia de una serie de circunstancias referidas por los mismos de índole económica, laboral y social, agravadas en los últimos años, que parecen repercutir de forma negativa en su correcto control ambulatorio. El objetivo del presente estudio es describir la influencia de estas variables sobre la evolución de la infección. Métodos: Estudio observacional, descriptivo, de corte transversal sobre una muestra constituida por los pacientes con infección VIH citados en Consultas Externas de Enfermedades Infecciosas en un periodo de tiempo comprendido entre el 9 de Marzo y el 10 de Abril del 2015. La recogida de datos se efectúa mediante un cuestionario estructurado y organizado en dos bloques, el primero a cumplimentar por el propio paciente y el segundo por el facultativo. El cuestionario incluye datos demográficos, sociolaborales y cuestiones en relación al seguimiento y tratamiento ambulatorio. Resultados: Muestra 153 pacientes, 144 encuestas evaluadas. 62.5% hombres, media de edad 45.67, 34% mayores de 50 años; 29.2% extranjeros; 50% con nivel de estudios primarios o inferior. Un 36.8% con problemas laborales (contratos temporales o sin contrato y en paro), 21.5% carece de ingresos económicos propios. En un 13.2% nadie del entorno conoce el diagnóstico de infección. Cambian la cita 15.9% por problemas laborales y de desplazamiento, faltan 12.6% por estos motivos. Un 86.8% presenta carga viral indetectable. Discusión: Se percibe todavía una situación de fondo de miedo al rechazo. Los fallos o cambio en el día de consulta reflejan como problema de fondo situaciones laborales precarias y problemas de desplazamiento de origen económico, a pesar de esto existe un buen control inmunovirológico
Telos and Repetition: Spirit and Banausia as an Art Quest
Este artículo está enmarcado en una investigación
sobre el uso de la repetición como recurso plástico en
arte contemporáneo. El análisis se centra en el estudio
de las motivaciones que llevan a los artistas a utilizar la
repetición más allá de intencionalidades conceptuales
o de significación. Para ello, se estudia de forma
comparativa la obra de dos artistas: Wolfgang Laib, quien
desarrolla una búsqueda de la espiritualidad a través de la
instauración de hábitos y rituales, e Ignacio Uriarte, quien
busca la alienación mediante obras realizadas con actos
burocráticos rutinarios. Este trabajo plantea el uso de la
repetición partiendo desde enfoques psicológicos hasta
consideraciones sobre la instauración de hábitos, mitos
y ritos, y la creación de espacios delegados y campos de
fuerzas, así como ideas sobre la sacralización del arte y el rol
del artista en nuestra sociedad.
Palabras clave: repetición; Wolfgang Laib; Ignacio Uriarte;
banausia; arte y espiritualidad.
This article is framed in a wider research about the use of
repetition as a plastic resource in Contemporary Art. The
article focuses on the study of the motivations that lead
artists to use repetition, without focusing on conceptual
intentions. With this purpose, the essay proposes a
comparative analysis of two artists: Wolfgang Laib, who
develops a search for spirituality through the use of habits
and rituals. And, Ignacio Uriarte; who searches alienation
working with bureaucratic routines. This text proposes
the use of repetition from psychological approaches to
considerations about the establishment of habits, myths
and rites and the creation of delegated spaces and fields of
forces, as well as ideas about the sacredness of art and the
role of the artist in our society.

Identification of pathogenic races 0, 1B/C, 5 and 6 of fusarium oxysporum f. sp. ciceris with random amplified polymorphic DNA
Abstract Ninety-nine isolates of Fusarium oxysporum f. sp. ciceris (Foc), representative of the two pathotypes (yellowing and wilt) and the eight races described (races 0, 1A, 1B/C, 2, 3, 4, 5, and 6), were used in this study. Sixty isolates were analyzed by the RAPD technique using DNA bulks for each race and 40 primers. Bands presumably specific for a DNA bulk were identified and this specificity was confirmed by further RAPD analysis of individual isolates in each DNA bulk. Primers OPI-09, OPI-18, OPF-06, OPF-10, and OPF-12 generated RAPD marker bands for races 0, 1B/C, 2, 3, 4, 5, and 6. The reliability and utility of this procedure was validated in 'blind trials' using 39 new Foc isolates. Ten of the 39 isolates had already been typed to race by pathogenicity tests and 29 were typed both by pathogenicity and RAPD testing in this study. In these 'blind trials', we assigned the 39 new isolates to a race solely on the basis of their RAPD haplotype. Thus, we concluded that Foc races 0, 1B/C, 5, and 6 can be characterized by the RAPD markers. Cluster analysis of the RAPD data set resulted in three clusters of isolates within Foc. The yellowing isolates were grouped in two distinct clusters which correspond to races 0 and 1B/C. The wilt isolates constitute a third cluster that included races 1A, 2, 3, 4, 5, and 6. These results provide a means of studying the distribution of Foc races, to assist in the early detection of introduced race(s) and to facilitate the efficient deployment of available host resistance
Status and trends of the fish community in the Flemish Cap (NAFO Div. 3M) bioregion
This report summarizes fish community trends for the Flemish Cap (NAFO Div. 3M) based on European Union
summer trawl research vessel surveys between 1988 and 2018. Species were classified into eight functional
groups and trends were described using biomass indices, biomass and abundance anomalies, and fish size
(Biomass/Abundance Ratio) anomalies. In 2003, a replacement of the research vessel allowed extending the
depth coverage of the survey from 700m to 1400m. The vessel change had an impact on survey catchability, so
to account for it conversion factors were applied. Considering the change in depth coverage, trends were
examined for 1988-2018 with data up to 700m, and for 2004-2018 with data up to 1400m. Fish community
trends were similar between the two datasets, but the analyses including deeper waters showed a
comparatively higher levels of benthivores, reflecting the changes in community structure with depth.
Generally speaking, trends in average fish size as tracked by the Biomass/Abundance Ratio appeared driven by
recruitment, where general declines in abundance and absences of good recruitments got reflected in increases
of this ratio. Biomass of plankpiscivores (mostly Sebastes sp.) experienced a sharp increase in the early 2000s
but then returned to levels comparable to the 1990s. Piscivores biomass showed a strong decline in the early
1990s due to the collapse of cod but has since shown signs of recovery. Shellfish, driven by northern shrimp,
saw a sustained increase in biomass from the early 1990s until 2002, when started a decline that has persisted
until 2018. The biomass of large benthivores decline in the late 1990s and remains low to this date

gestionades per l’Institut de Ciències de l’Educació i el Grup de Recerca en Orientació
Psicopedagògica (GROP), amb el tema Educació emocional a l’activitat física i l’esport els
dies 31 de març i 1 d’abril, amb uns 150 participants procedents no sols de Catalunya,
sinó també de la resta de l’Estat espanyol i Llatinoamèrica.
Els assistents són experts en els camps de la pedagogia, psicologia, psicopedagogia,
professorat d’educació física, entrenadors, àrbitres, atletes, ex-atletes d’elit, empresaris
del món esportiu, acròbates i persones interessades amb la temàtica. Tots ells han pogut
reflexionar sobre la importància d’educar les emocions a l’entorn de l’esport i l’activitat
física, i específicament en aspectes com l’autoregulació de l’esforç, de la frustració, del
respecte que cal tenir a les grades, del rol tan important que exerceixen els entrenadors,
la necessitat de la formació permanent, i especialment, de la prevenció de la violència a
les grades.
Les ponències dels experts, taules rodones, tallers, presentació de comunicacions i
pòsters, han estat una oportunitat de formació, sensibilització i formació per a la pràctica

Utilización de antibióticos en una farmacia comunitaria
La sociedad actual se caracteriza por una elevada intolerancia al malestar y una urgencia por solucionar molestias, incluso menores, que conduce a una demanda de utilización de los recursos disponibles, aunque no siempre se precisen, lo que influye en que el uso, entre otros, de antibióticos sea mucho mayor de lo deseable
Necesidades formativas de los profesionales de instituciones artísticas y socioeducativas en contextos inclusivos
La inclusión y la participación efectivas de las personas con diversidad funcional en el ámbito cultural y artístico es una asignatura pendiente. La formación de los profesionales que desarrollan e implementan proyectos artísticos y culturales podría ser un aspecto a mejorar, aunque no hay muchos estudios al respeto. Por eso, con esta investigación se pretende conocer la autopercepción de competencias relacionadas con los proyectos artísticos de tales profesionales, sus necesidades formativas en este ámbito y sus preferencias por diferentes modalidades formativas. Para ello, se recabó información de 102 profesionales que fueron seleccionados de forma incidental de 29 instituciones educativas, artísticas y/o culturales de Cantabria y Cataluña, mediante cuestionario, entrevista o grupos de discusión. Los resultados de este trabajo permiten afirmar, primero, que la autopercepción de competencias no es mala, pero existe un amplio margen de mejora; segundo, que las necesidades formativas identificadas, aunque diversas, parecen concentrarse en aspectos como el fomento de la participación activa de las personas o los conocimientos para diseñar e implementar verdaderos proyectos para todos; y, tercero, que para formarse en este ámbito, se aboga por un formato semipresencial. Por tanto, los datos alcanzados ponen de relieve la necesidad de mejorar la formación de los profesionales de la educación y de los espacios artísticos y culturales, mediante iniciativas interdisciplinares y trasversales que potencien el trabajo en red.The effective inclusion and participation of people with functional diversity in the cultural and artistic sphere is a pending issue. The training of professionals who develop and implement artistic and cultural projects could be an aspect to be improved; however, there are not many studies on the subject. Therefore, the aim of this research is to consider the self-perception of competences related to artistic projects of these professionals, their training needs in this area and their preferences for different training modes. To this end (To achieve that) the information was collected from 102 professionals who were selected incidentally from 17 educational, artistic and/or cultural institutions in Cantabria and Catalonia, by means of a questionnaire, interview or discussion groups. The results of this study provide the basis for the statements as follows. Firstly, the self-perception of competences is not bad, but there is much space for improvement. Secondly, the training needs are identified as diverse, but nevertheless, they seem to concentrate on either the promotion of the people's active participation or the knowledge needed for design and implementation of real projects for all. And thirdly, a blended learning format is advocated for training in this area. Hence, the obtained data highlights the need to improve the educational specialists' training as well as artistic and cultural spaces through interdisciplinary and cross-disciplinary initiatives that promote networking
Seasonal and intradaily variations of Parietaria pollen in the atmosphere of Málaga.
Parietaria pollen is one of the main causes of hay fever and asthma in the population, presenting a high
allergenicity. That is why, in order to inform the population, it is important to determine whether its behaviour
pattern is different in different parts of the city.
The objective of this study was to analyze and compare the behaviour pattern of the Parietaria pollen type
in two different points within the city of Malaga and to analyze the existing correlation between pollen
concentrations and the main meteorological parameters.
We used two Hirst-type volumetric pollen traps, one of them installed in the periphery and the other in
the city center, between 2017 and 2019. The samples were mounted and counted following the
recommendations of the Spanish Aerobiology Network. To calculate the annual pollen integral, the sum
of the mean daily concentrations throughout the year was used. To calculate the intradaily variations, the
values were accumulated every two hours, expressed as percentages of the daily total. In order to study
the relationships between meteorological parameters and pollen concentrations, Spearman correlation
tests have been carried out.
The values of the annual pollen integral were always much higher in the centre. Daily mean concentrations
showed the presence of this pollen type in the atmosphere throughout the year. Regarding the intraday
pattern, a more pronounced peak was observed in the city centre, while in the periphery, the distribution
is more homogeneous throughout the day. The meteorological parameters play an important role in
determining the daily concentrations in the atmosphere.
In the light of these results, we can conclude that it is necessary to install several sampling points within
the same city, due to its heterogeneity and different land uses, in order to inform the population with a
greater precision and, in this way, prevent respiratory allergies.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech
