Las traducciones italianas de las ‘Greguerías’ de Ramón Gómez de la Serna
No full textThis paper focuses on a comparative analysis of the six existing Italian translations of the Greguerías by Ramón Gómez de la Serna (1888–1963), all of them realized by a different trans-lator and spread in a period going from 1930 to 2010. The comparative translation analysis of these six translations highlights how the diachronic evolution of the target language, the sensitivity of the translator and the type of recipient affect the final product. Likewise, some characteristicsof thegreguería such as brevity, humour and the ludic effect that the author raises through rhetorical figures of thought and language demand from the translator a careful lexical selection and the use of specific techniques in order to reproduce the immediacy of the image that thegreguerías evoke
Falsificaciones y procesos judiciales. Contexto de producción y utilización de un supuesto original del monasterio de San Pedro de Cardeña
No full textThe oldest document preserved in the Archivo Histórico de la Nobleza (OSUNA, CP. 37, D. 9) is a parchment in Visigothic script dated December 26, 943. It is a donation from Asur Fernández –count of Castile at that time– and his wife, Countess Gontroda, to San Pedro de Cardeña, the most important Castilian monastery of that period. Given that most of the Cardeña documentary collection is considered lost, this could be the oldest surviving original from the monastic archive. Through an exhaustive palaeographical and diplomatic study of the parchment, as well as by tracing its textual transmission, it has been possible to establish that the document was indeed part of the Cardeña collection, but it is a forgery made in the twelfth century, on the basis of a genuine, now lost tenth-century model. On the other hand, this charter has been transmitted as part of a thirteenth-century collection related to one of the lawsuits in which it was used as evidence. This collection deserves attention, both for its intrinsic diplomatic interest and for the light it sheds on the judicial use of forged documents.El documento más antiguo existente en el Archivo Histórico de la Nobleza (OSUNA, CP. 37, D. 9) es un pergamino en escritura visigótica datado a 26 de diciembre de 943. Contiene una donación de Asur Fernández –entonces conde de Castilla– y su mujer Gontroda, al monasterio castellano de Cardeña. Podría tratarse del más antiguo original superviviente del archivo cardeniense, en su mayor parte perdido. Por medio de un exhaustivo estudio paleográfico y diplomático y el rastreo de su transmisión textual, se ha podido establecer que el documento, efectivamente, formó parte del archivo cardeniense, pero se trata de una falsificación elaborada en el siglo XII a partir de un modelo genuino del siglo X, hoy perdido. Por otra parte, el diploma se ha transmitido formando parte de un conjunto de documentos del siglo XIII relacionados con uno de los procesos judiciales en los que se utilizó como prueba, lo que ilumina el uso judicial de documentos falsificados
In situ biogas stripping of ammonia from a digester using a gas mixing system
No full textPrevious studies have suggested the use of digester biogas mixing systems for in situ ammonia removal from anaerobic digestates. The feasibility of this was tested at moderate and complete gas mixing rates at mesophilic and thermophilic temperatures in a 75-L digester. Experimental results showed that at gas mixing rates typical of full-scale commercial digesters the reduction in TAN concentrations would be insufficient to allow stable acetoclastic methanogenesis in mesophilic conditions, or to prevent total inhibition of methanogenic activity in thermophilic food waste digestion. Simulation based on batch column stripping experiments at 55 ?C at gas violent flow rates of 0.032 m3 m-2 min-1 indicated that ammonia concentrations could be reduced below inhibitory values in thermophilic food waste digestion for organic loading rates of up to 6 kg VS m-3 day-1. These mixing rates are far in excess of those used in full-scale gas-mixed digesters and may not be operationally or commercially feasible

Ammonia removal in food waste anaerobic digestion using a side-stream stripping process
No full textThree 35-L anaerobic digesters fed on source segregated food waste were coupled to side-stream ammonia stripping columns and operated semi-continuously over 300 days, with results in terms of performance and stability compared to those of a control digester without stripping. Biogas was used as the stripping medium, and the columns were operated under different conditions of temperature (55, 70, 85 °C), pH (unadjusted and pH 10), and RT (2 to 5 days). To reduce digester TAN concentrations to a useful level a high temperature (?70°C) and a pH of 10 were needed; under these conditions 48% of the TAN was removed over a 138-day period without any detrimental effects on digester performance. Other effects of the stripping process were an overall reduction in digestate organic nitrogen-containing fraction compared to the control and a recovery in the acetoclastic pathway when TAN concentration was 1770 ± 20 mg kg-1

Evaluation of microporous hollow fibre membranes for mass transfer of H<sub>2</sub> into anaerobic digesters for biomethanisation
No full textBACKGROUND With high surface‐to‐volume ratios, hollow fibre membranes offer a potential solution to improving gas–liquid mass transfer. This work experimentally determined the mass transfer characteristics of commercially available microporous hollow fibre membranes and compared these with the mass transfer from bubble column reactors. Both mass transfer systems are considered for biological methanization, a process that faces a challenge to enhance the H2 gas–liquid mass transfer for methanogenic Archaea to combine H2 and CO2 into CH4.RESULTS Polypropylene membranes showed the highest mass transfer rate of membranes tested, with a mass transfer coefficient for H2 measured as kL = 1.2 × 10−4 ms−1. These results support the two‐film gas–liquid mass transfer theory, with higher mass transfer rates measured with an increase in liquid flow velocity across the membrane. Despite the higher mass transfer rate from polypropylene membranes and with a liquid flow across the membrane, a volumetric surface area of α = 10.34 m−1 would be required in a full‐scale in situ biological methanization process with much larger values potentially required for high‐rate ex situ systems.CONCLUSIONS The large surface area of hollow fibre membranes required for H2 mass transfer and issues of fouling and replacement costs of membranes are challenges for hollow fibre membranes in large‐scale biological methanization reactors. Provided that the initial bubble size is small enough (de < 0.5 mm), calculations indicate that microbubbles could offer a simpler means of transferring the required H2 into the liquid phase at a head typical of that found in commercial‐scale anaerobic digesters
Anaerobic granular reactors for the treatment of dairy wastewater: a review
No full textConsiderable research has been conducted on the treatment of dairy wastewater by anaerobic granular reactors. Upflow anaerobic sludge blanket (UASB) reactors, anaerobic sequencing batch reactors (ASBR) and static granular bed reactors (SGBR) are the conventional granular reactor types most commonly applied in dairy wastewater treatment. Hybrid systems have also been developed to increase treatment efficiency and overcome the operational problems associated with the treatment of this substrate. Effects of parameters including temperature, organic loading and operating protocols on the performance of granular reactors are summarised. Individual and hybrid granular reactors are evaluated based on organic matter removal and methane production capacity
Pasionario del monasterio de San Pedro de Cardeña (British Library, Add. Ms. 25600): nuevas aportaciones sobre su datación y autoría
No full textEl Pasionario de Cardeña, manuscrito actualmente conservado en la British Library de Londres (Add. Ms. 25600), ha acaparado la atención de numerosos especialistas, especialmente desde comienzos del siglo pasado. A partir de esos primeros trabajos, la autoría y la datación del Pasionario ha venido suscitando ciertas controversias. De una primera adscripción al copista Gómez, en el año 919, se propuso después otro scriptor, Endura, y una cronología algo posterior, mitad del siglo x. Los análisis llevados a cabo para el presente trabajo nos llevan a plantear otras hipótesis que se alejan de ambos escribas y a descartar, definitivamente, el año 919 para este manuscrito.The Passionary of Cardeña, a manuscript currently preserved in the British Library in London (Add. Ms. 25600), has been the subject of numerous studies, especially since the beginning of the last century. Since those early works, the authorship and dating of the Passionary has been the subject of some controversy. Starting from a first attribution to the copyist Gómez, in the year 919, another scriptor, Endura, was later proposed, dating the manuscript to a later chronology, the middle of the 10th century. The analyses carried out by the present study lead us to propose other hypotheses that move away from both copyist and to definitively rule out the year 919 for this manuscriptEste trabajo se enmarca dentro del proyecto financiado por el Ministerio de Ciencia e Innovación (PDI2019-108273GB-I00) «Élites clericales y afianzamiento territorial e institucional de la diócesis de Burgos (siglos XI al XV)», dirigido por la Dra.
