The relationship between scatter-hoarding rodents and oak species has been considered on a scale from antagonism to mutualism. Depending on the costs and benefits, the outcome of the relationship can be found at one extreme or the other. Costs have included destruction of acorns that occurs during predation, but not all acorns attacked lose their embryos. As representatives of the mutualistic end, we present two species with this behavior (Mus spretus and Apodemus sylvaticus). Representing the antagonistic extreme, we present a predatory species that destroys the embryo (Microtus arvalis). The objective of this study is to test the preferences of both rodent groups for acorns. The results showed that there is one acorn species (Quercus ilex) that is preferred by the three rodent species. This acorn species has high concentrations of nutrients, low concentrations of tannins and thin shell. These characteristics attract the attention of rodents that could carry these acorns. There are two other acorn species (Quercus suber and Quercus rubra) that are consumed with little intensity for having low concentrations of nutrients, high concentration of tannins and thick shell. These characteristics escaping predators although transportation is not guaranteed. These acorns would germinate and emerge under the trees that have produced them and increase intraspecific competition. Coincidence preferences shown by the three rodent species poses a risk for the oak species, since the recent arrival of the predator (antagonist) species in the study area could paralyze the dispersal process carried out by the other two mutualistic species through predation., Departamento de Ciencias Agroforestales

Flexible 100 % bio-based films were produced from discarded carrots fractions. The main ingredient was purified high molecular weight fractions of hemicelluloses and pectins previously obtained by hydrothermal treatment and ultrafiltration/diafiltration. A fraction of lignin-containing cellulose nanofibers was used as an additive. These nanofibers were obtained from the residual pulp of the hydrothermal treatment after a mechanical treatment. Low content of lignin-cellulose nanofibers (< 5 % w/w) improved oxygen permeability (up to 29 %) but worsened water vapor permeability and tensile properties. A higher addition of lignin-cellulose nanofibers (5-25 % w/w) allowed to recover the properties of the reference film (without fibers) and provided a higher hydrophobicity, increasing the water contact angle from 79.9° to 125.8°. The study of the influence of the molecular weight (67.77-102.75 kDa) and composition of the hemicellulose and pectin fraction in films containing 1 % lignin-cellulose nanofibers showed that a higher molecular weight decreased oxygen permeability (from 48.18 to 41.14 cm3·µm/m2/kPa/day), increased water vapor permeability (from 21.56 to 24.01 g·mm/m2/kPa/day) and decreased hydrophobicity (from 86.84° to 71.10°). Tensile stress was higher with higher pectin content and lower molecular weight (from 1.13 to 2.84 MPa), while elongation was higher with higher hemicellulose content (from 5.92 to 15.28 %). The obtained films had acceptable properties for food packaging and high hydrophobicity, with the great advantage of being 100 % from agri-food waste by applying environmentally friendly processes and without the need for chemical modification., Grupo de Tecnologías a Presión (PressTech), Agencia Estatal de Investigación (Gobierno de España) and FEDER Funds EU [PID2019-105975GB-I00 (MICINN/FEDER, EU)], Junta de Castilla y León - Consejería de Educación and FEDER Funds [CLU-2019-04]

Discarded carrots were valorized to obtain different films. The pulp was subjected to hydrothermal treatment (140 and 180 °C) at pilot scale, with one and with several flow-through reactors in series, allowing the extraction of pectin-containing arabinogalactan (P-AG) of very high molecular weight. Ultrafiltration and diafiltration allowed obtaining purified fractions with molecular weights be-tween 3.48-102.75 kDa. The solid residue from the hydrothermal process was subjected to mechanical treatments to obtain lignin-containing cellulose nanofibers (L-CNFs). The P-AG film had a better oxygen barrier (67.73 vs. 239.83 cm3·µm/m2/kPa/day) and the L-CNFs film had a higher tensile strength (7.74 vs. 3.14 MPa). The combination of both fractions showed that L-CNFs should be added in percentages higher than 15 % (w/w) so that their presence does not harm the P-AG based film. There was a synergistic effect on hydrophobicity when mixing both fractions, reaching a 57.5 % higher water contact angle (125.8 °). As for the P-AG sample, a higher molecular weight decreased the oxygen permeability up to 14.6 % (41.14 cm3·µm/m2/kPa/day) but increased the water vapor permeability up to 11.4 % (24.01 g·mm/m2/kPa/day). The tensile strength was up to 150.9 % higher at lower molecular weight and higher pectin content (2.84 MPa) due to the high degree of branching of the arabinogalactan. Elongation was up to 157.9 % higher at higher arabinogalactan content (15.28 %). For the first time, purified fractions of P-AG and L-CNFs from carrot waste were obtained and used for film formation. The films had acceptable properties for food-packaging., Grupo de Tecnologías a Presión (PressTech), Instituto de Bieconomía de la Universidad de Valladolid, Agencia Estatal de Investigación (Gobierno de España) and FEDER Funds EU [PID2019-105975GB-I00 (MICINN/FEDER, EU)] Junta de Castilla y León - Consejería de Educación and FEDER Funds [CLU-2019-04]

El honor atribuido a san Jerónimo, como patrón de los traductores, por su magna empresa de traducción de la Biblia al latín vulgar (Vulgata), o el reconocimiento como “Santos Traductores” de la Iglesia Apostólica de Armenia, por aquella misma época (siglo V), constituyen un claro ejemplo de cómo la traducción puede ser una vía hacia la santidad. El trabajo de mediación textual, en muchos casos pionero, que sigue las normas de la época o de la comunidad, se enfrenta a situaciones que trascienden del mero intercambio escrito o verbal y se acerca a situaciones en las que el lector o el público en general se ponen en contacto con el mensaje divino. A lo largo de nuestra contribución se pasa revista a algunos momentos de la historia de la traducción en los que los religiosos, enfrascados en su labor traductora o de servicio a la traducción o interpretación, y en situaciones generalmente de misión, alcanzan la dignidad de santos, beatos, venerables o mártires., Departamento de Filología Francesa y Alemana
