Experimental colonization of Ulva spp. with algal-epiphytic antagonistic bacteria as a strategy for pathogen control in integrated multi-trophic aquaculture recirculating systems

Probiotics are a potential tool for bacterial control in aquaculture (Pintado et al. 2011), decreasing the use of disinfectants and antibiotics and contributing to an ecosystem approach, which is more sustainable and respectful to the environment.Postprint (published version

Explaining the electoral performance of radical right parties in Europe (2008-2019): a fuzzy-set Qualitative Comparative Analysis

Although radical right parties have been extensively examined since their significant breakthrough in the European political arena in the late 80s, not enough attention has been paid to the reasons behind their unequal electoral performance (or in other words, to the cross-national and within-national variations of their success). The aim of this research is to identify the different scenarios of electoral success for radical right parties in ten European countries between 2008 and 2019. Using fuzzy-set Qualitative Comparative Analysis (fsQCA) -a case-oriented technique which allows in-depth comparative examination and which is based on the concepts of equifinality and causal heterogeneity-, we test the role of several causal conditions related to some demand-side and supply-side explanations. Our results reveal four sufficient causal paths that lead to the success of these parties, which confirm that they are able to achieve relevance in quite diverse contexts. The four paths combine both demand-side and supply-side conditions, but the role of the latter is qualitatively and quantitatively more important. In particular, we see how radical right parties can effectively take advantage of favorable political competitive dynamics, even in the absence of a priori favorable socio-economic contexts. Overall, our findings run contrary to some mechanistic explanations in the literature and support the idea of conceiving of the radical right parties as a complex, multiform phenomenon which needs to be understood through both theoretical and methodological innovations.The authors would like to thank Jorge Ramos for his valuable comments and suggestions on previous versions of this article.

La invención del homo economicus y la expulsión de la ética de la economía. ¿Un camino sin retorno?

En el presente artículo, a través de una revisión bibliográfica, se analizan las relaciones que se establecen entre la Ética y la Economía y cómo la invención del concepto de homo economicus propicia y culmina la separación entre ambas disciplinas. La revisión de las críticas de A. Sen y A.O. Hirschman a este reduccionista concepto de agencia humana, permite mostrar que, sin embargo, el vínculo entre ambos campos de pensamiento no se había roto definitivamente. En la última sección, a modo de conclusión, planteamos que existen indicios en el campo de la investigación y de la acción social que indican que ese vínculo se está restaurando, que la separación de la Economía y la Ética es un camino con retorno, y que de esta forma toda la disciplina estará mejor armada para enfrentarse, teórica y prácticamente, a los principales desafíos humanos actuales

Design space exploration in heterogeneous platforms using OpenMP

In the fields of high performance computing (HPC) and embedded systems, the current trend is to employ heterogeneous platforms which integrate general purpose CPUs with specialized accelerators such as GPUs and FPGAs. Programming these architectures to approach their theoretical performance limits is a complex issue. In this article, we present a design methodology targeting heterogeneous platforms which combines a novel dynamic offloading mechanism for OpenMP and a scheduling strategy for assigning tasks to accelerator devices. The current OpenMP offloading model depends on the compiler supporting each target device, with many architectures still unsupported by the most popular compilers, such as GCC and Clang. In our approach, the software and/or hardware design flows for programming the accelerators are dissociated from the host OpenMP compiler and the device-specific implementations are dynamically loaded at runtime. Moreover, the assignment of tasks to computing resources is dynamically evaluated at runtime, with the aim of maximizing performance when using the available resources. The proposed methodology has been applied to a video processing system as a test case. The results demonstrate the flexibility of the proposal by exploiting different heterogeneous platforms and design particularities of devices, leading to a significant performance improvement.This work has been funded by FEDER/Ministerio de Ciencia, Innovación y Universidades – Agencia Estatal de Investigacion/TEC2017-86722-C4-3-R, also under the FitOptiVis Project (ECSEL2017-1-737451), which is funded by the EU (H2020) and Ministerio de Ciencia, Innovación y Universidades

Prevalence of Type VI Secretion System in Spanish Campylobacter jejuni Isolates.

Infections from Campylobacter jejuni pose a serious public health problem and are now considered the leading cause of foodborne bacterial gastroenteritis throughout the world. Sequencing of C. jejuni genomes has previously allowed a number of loci to be identified, which encode virulence factors that aid survival and pathogenicity. Recently, a Type VI secretion system (T6SS) consisting of 13 conserved genes was described in C. jejuni strains and recognised to promote pathogenicity and adaptation to the environment. In this study, we determined the presence of this T6SS in 63 Spanish C. jejuni isolates from the food chain and urban effluents using whole-genome sequencing. Our findings demonstrated that nine (14%) strains harboured the 13 ORFs found in prototype strain C. jejuni 108. Further studies will be necessary to determine the prevalence and importance of T6SS-positive C. jejuni strains

Influencia de la incorporación del plástico PVC reciclado en las propiedades del ladrillo de concreto en Comas, Lima - 2021

La presente Tesis realiza el análisis y evaluación del desempeño de ladrillos de concretos hechos de PVC, el cual se desarrolló en base a la problemática observamos muchas viviendas que presentan problemas en sus estructuras, ladrillos salitrosos o viviendas de tabiquería, ante este requerimiento se plantea crear un tipo de ladrillo ecológico de PVC. La investigación tuvo como objetivo crear un tipo de ladrillo ecológico de PVC, para comprender las propiedades del ladrillo de concreto, garantizando la resistencia a la compresión, porcentajes de vacíos y absorción de agua, dando paso una mejor calidad, donde contribuya con la mejora ambiental de nuestro planeta. Para el desarrollo de la investigación se realizaron búsquedas en bases de datos de revistas científicas reconocidas. Se establecieron los límites de búsqueda desde el año 2015 en adelante. La muestra será conformada por 52 ladrillos de concreto con dimensiones de 13.2cm x 10.2cm x 23.2cm, la cual tendrá en su composición de cemento, agregado fino, agregado grueso y agua, en el cual se añadirá plástico de PVC en porcentajes de 25%, 40% y 80% respectivamente. Los resultados obtenidos muestran que las propiedades de unidades de ladrillo de concreto elaborados con residuos plásticos de PVC tienen resultados óptimos

Relational intelligence, artificial intelligence and citizen participation: the case of the Cooperative Digital Platform Les Oiseaux de Passage

Este artículo analiza cómo los principios y los valores cooperativos de la economía so cial son los más pertinentes para potenciar una inteligencia relacional que supere los potencia les efectos adversos para personas y territorios de la delegación de las relaciones humanas en una inteligencia artificial basada en valores capitalistas. El análisis se basa en el estudio del caso de la plataforma cooperativa francesa Les Oiseaux de Passage, que da soporte a diferen tes comunidades patrimoniales europeas en la puesta en valor de su patrimonio cultural a través de actividades ligadas al sector turístico. En este caso, la tecnología opera como desin termediadora, desautomatizadora y desestandarizadora, aportando mayor transparencia y equidad al conjunto de relaciones que se establecen y contribuyendo al desarrollo de relacio nes más horizontales y a la democracia económica entre los socios y con las personas visitan tes.This article analyzes how the cooperative principles and values of the social economy are the most pertinent to enhance a relational intelligence that overcomes the potential adverse effects for people and territories of the delegation of human relations in an artificial intelli gence built on capitalist values.
