En busca de la precisión: análisis de una configuración manual en el Diccionario normativo de la lengua de signos española

Además de lo que en mi crecimiento académico y personal ha supuesto el magisterio de Guillermo Rojo, no hay duda de que su trabajo constante y diverso ha ido abriendo caminos a muchos otros lingüistas y su aportación continúa constituyendo un referente y un estímulo en la actualidad. Así es en particular en la adaptación de herramientas informáticas para la investigación de la lengua española, pero también en la búsqueda de soluciones nuevas para los viejos retos de la Lingüística. Su contribución a la modernización y disponibilidad de los diccionarios y otros recursos de la Real Academia de la Lengua es enorme e indispensable. No solo son útiles a quienes estudian la lengua española, ya que otros materiales y otros proyectos, en principio ajenos a los objetivos de la RAE, se han beneficiado de esta labor. Es el caso del Diccionario normativo de la lengua de signos española (Fundación CNSE 2008) (en adelante DNLSE), para cuya realización la RAE cedió las definiciones del Diccionario de la lengua española. Sirva esta entrada como justificación de por qué he elegido como fuente de los datos del trabajo con el que quiero contribuir a este homenaje un producto que, sin ser directamente obra suya, está vinculado con la Real Academia Española de la Lengua y resulta además de gran utilidad para una investigación sobre la lengua de señas de los sordos

Argument and verb meaning clustering from expression forms in LSE

Languages use predicates and arguments to express events and event participants. In order to establish generalizations concerning the variety languages show regarding the strategies for discerning some arguments from the others, the concept of roles—and, particularly, macroroles, mesoroles, and microroles—associated with participants provides a widely studied starting point. In this article, the formal properties in the arguments of a set of 14 verb meanings in Spanish Sign Language have been analyzed. Arguments have been studied by considering their microroles, and a quantitative method for measuring distances from a plurality of properties has been adopted. The novelty of this analysis is that it focuses on how arguments group in terms of these properties. Subsequently, some generalizations justifying why some verb meanings have a tendency to associate with certain forms of argument expression are highlighted in this study.Ministerio de Economía y Hacienda | Ref.

Evaluation of the behavior of an innovative thermally activated building system (TABS) with PCM for an efficient design

The global energy crisis has caused a double effect. On the one hand, users are increasingly aware of the energy cost they face. On the other hand, public administrations have become aware of the importance of limiting energy consumption in buildings as a way to combat climate change and reduce the energy dependence with the climate. This situation supposes a great opportunity for innovative constructive solutions with an energetic behaviour that surpasses the traditional approach of reduction of the transmittance. In this work, studies are presented to obtain potential of a new solution thermally activated with two innovations with respect to those existing in the market: its activation is done by hot / cold water produced by renewable systems; and its concrete structural element in addition to having coupled the heat exchanger presents an innovative mortar doped with PCM microencapsulated phase change material.Ministry of Economy and Competitiveness (Government of Spain) and European Regional Development's funds (ERDF) project “Zero-Energy Balance Districts Through Algorithms of Adaptive Comfort and Optimal Management of Energy Networks” (BIA2016-77431-C2-2-R)University of Seville (Spain) Plan VI (VPPI-US

Defects in female fertility due to mutations in cohesins

Meiosis is a fundamental process in the improvement of genetic diversity, thus allowing the generation of new allelic combinations.This process consists of two consecutive rounds of nuclear divisions, known as meiosis I (MI) and meiosis II (MII), which ensure the correct distribution of chromosomes from diploid parental cells to haploid gametes (León-Periñán & Fernández-Álvarez., 2020). Throughout this process, cohesion is required to hold sister chromatids together until their separation in anaphase. Cohesion is created by subunit complexes of multiple proteins called cohesins; these proteins are essential for chromosome structure and segregation during meiosis. To date, several studies link defects in cohesins to female infertility. The model organism Schizosaccharomyces pombe is used to study the molecular mechanisms related to cohesins. During meiotic prophase, chromosome oscillations driven by cytoskeletal forces aim to move chromosomes to promote recognition and pairing between homologues and defects in these events lead to negative impacts on chromosome segregation (Hopkins et al., 2014). To observe these events, the functions of some proteins or factors involved in the behavior of cohesins such as the Pds5, Rec8 or Rec7 proteins have been studied. Different studies agree that the Pds5 protein determines the binding of cohesin to chromosomes, controls the binding capacity of sister chromatids and participates in gene expression (Misulovin et al., 2018). In order to observe the impact of this protein, S. pombe strains with a deletion in the Pds5 gene are studied by fluorescence microscopy using the DeltaVision microscope. As results, altered chromosome oscillations and segregations have been obtained in Pds5 mutants with respect to controls without this type of mutation, which could be extrapolated to a nefarious meiotic process in this context. In short, our results position Pds5 as a marker that can anticipate small fertility failures in women

Tuning Proton Conductivity Properties of Lanthanide Amino-Sulfophosphonates-Loaded Nafion Composite Membranes

Polymer-based electrolytes in proton exchange membrane fuel cells (PEMFCs) utilize acidic groups as proton carriers and hydrogen bonding networks as proton-conducting pathways to facilitate proton transport. Crystalline acid-functionalized metal phosphonates are potential proton conductors while maintaining a high hydration degree below 100 °C. This property may be combined with Nafion-like polymers which tend to dehydrate at the operating conditions of PEMFCs [1,2]. In this work, preliminary results of the preparation of lanthanide amino-sulfophosphonates-loaded Nafion composites membranes and the corresponding electrical properties are reported. Synthesis conditions of lanthanide derivatives were optimized following a hightrough-put screening at 140 °C. Their crystal structures, solved from synchrotron X-ray powder diffraction data, corresponds to layered frameworks where the acidic groups, -CPO3H or -SO3H, point toward the interlamellar region interacting by H-bond with the lattice water. The composites were prepared by mixing the metal phosphonates with Nafion solution at different loadings. The membranes were characterized by SEM, XRD and FT-IR. A study of the proton conductivity as a function of the composite membranes was carried out at 90 °C and 95% RH. Referencias [1] Y. Gao, R. Broersen, W. Hageman, N. Yan, M. C.

Use of Sub-Atmospheric Pressure Storage to Improve the Quality and Shelf-Life of Marmande Tomatoes cv. Rojito

In this study, the feasibility of storing Marmande tomatoes (Solanum lycopersicum, cv Rojito) under hypobaric conditions was evaluated. The fruits were sorted into four lots of 72 fruits each. One lot was considered as a control, and the fruits were kept in the open box, while the fruits of the rest of the three remaining lots were enclosed in airtight containers and subjected to 101, 75 and 50 Kpa, respectively. Control fruits and airtight containers were kept at room temperature, and every three days from the beginning of the experiment the following main quality parameters were analysed: ethylene production rate, firmness, colour, total solids content, ascorbic acid, total phenolics and pigments, as well as a sensory analysis carried out by panellists. The results show that sub-atmospheric storage led a reduction in ethylene production, which was associated with a delay in ripening. The differences in the evolution of pigments were very significant, while a large degradation of chlorophylls was observed in the control fruits and in those kept at 101 kPa, in the fruits kept at 75 kPa and 50 kPa the degradation was much slower. In relation to carotenoid pigments, it was observed that sub-atmospheric treatments delayed their appearance compared to control and 101 kPa fruits. In relation to other quality parameters, it was found that control fruit and fruit held at 101 kPa softened more rapidly than fruit under sub-atmospheric conditions, whose loss of firmness was more gradual with differences found only at 9 and 12 days of storage with respect to fruit firmness at harvest. The appearance of these fruits was evaluated with the same score as at the time of harvesting, during 9 of the 12 days of the experiment, then a positive effect of sub-atmospheric treatments was also found in the sensory analysis. The results suggest that sub-atmospheric storage could be a suitable method of increasing the shelf-life of fruits

Electrocatalytic properties of metal hydroxy-phosphonoacetate derivatives for OER, ORR and HER

Proyecto Nacional PID2019-110249RB-I00, Ayudas para contratación de Investigadores Docteres de la Junta de Andalucía PAIDI2020, Plan Propio de Investigación de la Universidad de Málaga para la contratación predoctoral (PRE2020-094459).Although Pt and Ru/Ir-based noble metal materials are the state-of-the-art electrocatalysts for energy storage and conversion, their applications are still limited by their scarcity and high price. Therefore, the design of low-cost and efficient electrocatalysts is highly desired and full of challenge. Herein we report the electrochemical properties of several metal phosphonates derived from the reaction of (R,S)-2-hydroxyphosphonoacetic acid (HPAA) with transition metals (M = Fe2+, Co2+, Mn2+, Ni2+), including their corresponding solid solutions. By pyrolytic treatment under N2 or 5% H2/Ar, materials having a wide range of compositions (phosphate, pyrophosphate, phosphides…) have been prepared and their electrochemical properties tested for OER and ORR and HER. Pyrolyzing in N2 at 500 °C, led to amorphous pyrophosphates, with Fe2+/Co2+ solid solutions displaying the lowest overpotential for the OER, whereas the Mn2+ derivative showed the best performance for the ORR. At higher temperature, pyrolyzed materials were crystalline pyrophosphates (N2) or metal phosphides (H2-Ar). In general, the latter compounds displayed better performances for the HER, Ni2P being the most active electrocatalyst. Addition of reduced graphene oxide (rGO) significantly improved the behaviour of the electrocatalysts for OER and ORR.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech

Effects of Fertigation Management on the Quality of Organic Legumes Grown in Protected Cultivation

Appropriate fertigation management plays an important role in increasing crop quality and economizing water. The objective of the study was to determine the effects of two fertigation treatments, normal (T100) and 50% sustained deficit (T50), on the physico-chemical quality of legumes. The determinations were performed on the edible parts of peas, French beans and mangetout. The trials were conducted in a protected cultivation certified organic farm. The response of legumes to the treatments varied between the cultivars tested. The fertigation treatments had a significant effect on the morphometric traits (width for mangetout and French bean; fresh weight for French bean; seed height for Pea cv. Lincoln). The total soluble solids and citric acid content have been shown to be increased by low soil water availability (T50) for mangetout. Fertigation treatments did not significantly affect the antioxidant compounds (total phenolic and ascorbic acid), minerals and protein fraction contents of legumes studied. Regarding legume health benefits, the most prominent cultivars were BC-033620 pea and French bean because of their high total phenolic (65 mg gallic acid equivalent 100 g−1 fresh weight) and ascorbic acid content (55 mg ascorbic acid 100 g−1 fresh weight), respectively. The results expand our knowledge concerning the nutraceutical quality and appropriate cultivation methods of legumes in order to make the system more sustainable and to encourage their consumption
