Aportación documental a la obra de Rojas Zorrilla

La bibliografía de Rojas Zorrilla constituye una de las más complejas en el estudio del teatro áureo, por lo que la publicación de un documento notarial sobre la venta de ocho de sus comedias, que han sufrido diversos avatares a lo largo de la tradición bibliográfica, puede considerarse de interés. El presente artículo, transcribe el contrato, e investiga cada una de estas comedias que Rojas Zorrilla vendió como propias, con el fin de clarificar el estado actual de la cuestión y despejar el camino a futuras investigaciones sobre el autor.Rojas Zorrilla’s bibliography is one of the most complex in the golden theatre research. The publication of a notaries document about the sale of eight of his theatre works, which have suffered different vicissitudes throughout the bibliographic tradition, can be considered of a great interest. The current article, transcribe the contract, and research of each of the Rojas Zorrilla’s comedies which he sold as made on his own, with the aim of clarifying the current situation of this question and of cleaning up the way for future research about this author

A Meta-analysis of Gut Microbiota in Children with Autism

Previous studies have reported dysbiosis in the gut microbiota (GM) of children with autism spectrum disorders (ASD), which may be a determining factor on child development through the microbiota-gut-brain axis. However, it is not clear if there is a specific group of dysbiotic bacteria in ASD. The aim of this study was to carry out a meta-analysis on the studies that analyze GM in children with ASD. 18 studies fulfilled our selection criteria. Our results showed a lower relative abundance of Streptococcus (SMD+ = − 0.999; 95% CI − 1.549, − 0.449) and Bifidobacterium genera (SMD+ = − 0.513; 95% CI − 0.953, − 0.073) in children with ASD. Overall, the Bifidobacterium genera is involved. However, differences found between studies are attributed to factors such as reporting bias

Superhydrophobic substrates allow the generation of giant quasi-static bubbles

We report on experiments of the quasi-static growth and detachment of air bubbles in water from a superhydrophobic substrate, overcoming the maximum size limitation of conventional injectors due to the Rayleigh–Taylor instability. The observations are in good agreement with a hydrostatic model, demonstrating that bubbles grow through a sequence of quasi-equilibrium states. Our experiments corroborate the theoretical prediction of a maximum bubble volume of approximately 6.04pi and a critical base radius of 3.22, both numbers in units of the capillary length (Michael &# Williams, Proc. R. Soc. Lond. A. vol. 351, 1976, pp. 117&;8211#127). This maximum is also reached when bubbles grow in an unbounded, ideally non-wetting surface, establishing the ultimate size limit of quasi-static bubble formation.This work has been supported by the Spanish MINECO under Projects DPI2017-88201-C3-2-R and DPI2017-88201-C3-3-R, partly financed through European funds, and by Universidad de Jaén Project Ref. 1263528 funded by Programa Operativo FEDER Andalucía 2014–2020.

Una nota biográfica sobre Jerónimo de Cáncer y Velasco

The place and the date of the Jerónimo de Cáncer’s birth have been questioned several times. This article tries to resolve some familiar data, specially those which are related to the emigration of the dramatist’s father Fadrique Cáncer and his wife, from Spain to isla Margarita. These facts can help us to deduce the data about the poet Jerónimo’s birth.La fecha y lugar de nacimiento del dramaturgo Jerónimo de Cáncer han sido cuestionados en numerosas ocasiones. Distintos investigadores intentaron localizar —de manera infructuosa— la documentación sobre el origen del poeta, lo que ha impedido fijar una datación correcta hasta el momento. El presente artículo trata de aportar algunas noticias familiares, especialmente referidas al traslado de Fadrique Cáncer y su mujer a América, para deducir una controvertida hipótesis sobre el nacimiento del poeta

Documentos sobre Jerónimo de Cáncer y su familia (parte II)

La figura de Jerónimo de Cáncer ha sido estudiada, en estas últimas décadas, desde distintas perspectivas. Sin embargo los datos biográficos conocidos siguen siendo muy escasos. El presente artículo pretende aportar algunos documentos inéditos sobre la vida del dramaturgo áureo, con el fin de abrir el camino a una biografía más completa y rea

Discovery of lost genes in the genome of Acinetobacter baumannii using Anablast

Motivation: Microbial resistance to antibiotics is currently one of the greatest threats in global health. Multiple outbreaks of multi-resistant Acinetobacter baumannii strains have been documented [1] and it is necessary to find new drugs against it, and the finding of new genes in the bacteria could help in this fighting. As A. baumannii is a highly studied organism, it is difficult to find new genes by homology with traditional predictors.For this reason we have chosen the AnABlast program which is a new bioinformatics tool which has been successful in finding out new genes in eukaryotes. This program generates profiles of accumulated alignments in query amino acid sequences using a low-stringency BLAST strategy [2], which highlight regions with evolutionary meaning.Methods: First, we used AnAblast to locate new coding regions in the A. baumannii genome. After that we analyzed the regions found by AnABlast comparing them with known sequences from the GenBank database to look for the genes found in intergenic regions and we obtain a series of candidates that we need to analyze, characterize and validate.Results: We obtained nine candidates that have been characterized analyzing both its evolutionary conservation and function annotation. Eight of them were also found in other strains of A. baumannii and one could be a gene not found until now that needs to be validated.Conclusions: Using the AnABlast program we have found nine possible coding regions not detected by other methods in the reference strain of A. baumannii. Although they need validation, AnAblast has proven itself useful for gene detection in prokaryote

Adopción de tecnologías verdes y su influencia en las prácticas de responsabilidad ambiental. Percepciones de los trabajadores de hoteles

El objetivo de este trabajo fue analizar desde la percepción de los trabajadores la influencia de la adopción de las tecnologías verdes en las prácticas de responsabilidad ambiental. Para ello, se aplicó una encuesta a 385 trabajadores de 74 hoteles de la Ciudad de México. En el tratamiento de datos se empleó la modelación de ecuaciones estructurales por mínimos cuadrados parciales. Los resultados evidencian que las prácticas de responsabilidad ambiental están soportadas por la adopción de tecnologías verdes según la estructura de costos, el ahorro de recursos y los beneficios que ofrecen. El valor del trabajo radica en exponer la perspectiva de los trabajadores como stakeholders internos de las empresas. The objective was to analyze the influence of the adoption of green technologies on environmental responsibility practices from the perspective of workers. For this purpose, a survey was applied to 385 workers of 74 hotels in Mexico City. Partial least squares structural equation modeling was used for data processing. The results show that environmental responsibility practices are supported by the adoption of green technologies according to the cost structure, resource savings, and the benefits they offer. The value of the work lies in exposing the perspective of workers as internal stakeholders of the companies.UAEME
