Bivariate orthogonal polynomials in the Lyskova class

AbstractClassical orthogonal polynomials in two variables can be characterized as the polynomial solutions of a matrix second-order partial differential equation involving matrix polynomial coefficients. In this work, we study classical orthogonal polynomials in two variables whose partial derivatives satisfy again a second-order partial differential equation of the same type

Semiclassical orthogonal polynomials in two variables

AbstractIn this work, semiclassical orthogonal polynomials in two variables are defined as the orthogonal polynomials associated with a quasi definite linear functional satisfying a matrix Pearson-type differential equation. Semiclassical functionals are characterized by means of the analogue of the structure relation in one variable. Moreover, non trivial examples of semiclassical orthogonal polynomials in two variables are given

Spatial and temporal dynamics of nutrients during the first filling years of a Mediterranean reservoir

Se ha estudiado la evolución espacio-temporal de variables limnológicas clásicas en un embalse mediterráneo: Rules, en la provincia de Granada, tras su inauguración. La dinámica de los nutrientes y de la clorofila-a está fuertemente condicionada por: (i) los aportes a través de las aguas fluviales; (ii) la actividad fotosintética en las capas superiores de la columna de agua y (iii) la acumulación de ortofosfato y de amonio en el hipolimnion anóxico durante la estratificación térmica. La tasa de sedimentación en el embalse de Rules muestra un claro gradiente creciente en el sentido presa-cola, reflejando la importante contribución de material alóctono fluvial. Finalmente, la comparación de las concentraciones totales de fósforo y nitrógeno tras 10 años de funcionamiento, en los que, entre otros factores, ha mejorado la depuración de aguas residuales en la cuenca de captación, ha mostrado una drástica disminución.The spatio-temporal evolution of classical limnological variables has been studied in a Mediterranean reservoir: Rules, in the province of Granada, after its inauguration. The dynamics of nutrients and chlorophyll-a is strongly conditioned by: (i) contributions through fluvial waters; (ii) the photosynthetic activity in the upper layers of the water column and (iii) the accumulation of orthophosphate and ammonium in the anoxic hypolimnion during summer thermal stratification. The sedimentation rate in Rules Reservoir shows a clear increasing gradient in the dam-tail direction, reflecting the important contribution of allochthonous fluvial material. Finally, the comparison of the total concentrations of phosphorus and nitrogen after 10 years of operation, in which, among other factors, the purification of wastewater in the catchment basin has improved, has shown a drastic decreas

Epistemological approach to translation and accessibility in the digital context: a taxonomy proposal

Las modalidades de Traducción e Interpretación Accesible (TeIA) han sido amplio objeto de investigación desde los estudios de Traducción Audiovisual (Díaz Cintas 2007a; Orero 2007; Álvarez de Morales et al., 2012). Sin embargo, su delimitación en el contexto digital se encuentra en un estado aún propedéutico (Greco 2019: 19). En el siguiente artículo realizamos una reflexión sobre la revisión bibliográfica (Jiménez Hurtado 2007; Tercedor et al., 2007a; Báez Montero 2010; Martínez 2015; Cabezas Gay 2017; Medina Reguera 2018) para delimitar su ubicación epistemológica dentro del contexto específico de estudio, definiendo las particularidades que distinguen a las modalidades de TeIA y aportando finalmente una propuesta de taxonomía específica que incluye la descripción verbal, la interpretación a códigos visuales gestuales, la transcripción y la adaptación textual. Su análisis y estudio como elementos del Diseño Universal es clave para profundizar en la implementación de soluciones de accesibilidad efectivas para los todos los usuarios.Accessible Translation and Interpreting Modalities have been extensively researched by the Audiovisual Translation Studies (Díaz Cintas 2007a; Orero 2007; Álvarez de Morales et al., 2012). However, its delimitation in the digital context is still in a propaedeutic stage (Greco 2019: 19). In the following article, we study the bibliographic review (Jiménez Hurtado 2007; Tercedor et al., 2007a; Báez Montero 2010; Martínez 2015; Cabezas Gay 2017; Medina Reguera 2018) according to the last Audiovisual Modalities in Translation and Interpreting in order to delimit its epistemological location within the specific context of study, in one hand, we will define the particularities that distinguish them and, on the other hand, we will provide a proposal for a specific taxonomy that includes the verbal description, the interpretation of visual-gestural codes and the transcription and the text adaption. Its analysis and further research, considered as elements of Universal Design, is key to deepen the implementation of effective accessibility solutions for all users

Public building works in the Municipal Archives of Santa Fe: The architect Francisco Fábregas Vehil (1925-1934)

Santa Fe inicia la remodelación de su edilicia pública durante la Dictadura de Primo de Rivera a raíz de tres decisiones municipales: construir un local apropiado para las Escuelas, un nuevo Ayuntamiento, y modernizar la imagen de la ciudad ante la celebración de la Exposición Iberoamericana de Sevilla en 1929. El proyecto (Casa Consistorial, Mercado con Matadero, Escuelas, Pavimentación y Alcantarillado, y dos Lavaderos) se encarga a la empresa “Técnica de Construcción, S.A” y a su arquitecto Francisco Fábregas Vehil, quien realizó los proyectos y dirigió las obras desde Sevilla y Barcelona hasta bien entrada la Segunda República.Rebuilding work in Santa Fe started during the Primo de Rivera Dictatorship, as a consequence of three municipal decisions: to build an appropriate building to house the schools; to construct a new Town Hall, and to give the town a look of modernity, given the imminent celebration of the Latin American Exhibition in Seville in 1929. The contract (for the town hall, the market and slaughterhouse, schools, paving and drainage work) was given to the firm “Técnica de Construcción, S.A” and their chief architect Francisco Fábregas Vehil, who carried out the project and supervised the building work from Seville and Barcelona, until well into the Spanish Second Republic

Characterization of New Proteomic Biomarker Candidates in Mucopolysaccharidosis Type IVA

Mucopolysaccharidosis type IVA (MPS IVA) is a lysosomal storage disease caused by mutations in the N-acetylgalactosamine-6-sulfatase (GALNS) gene. Skeletal dysplasia and the related clinical features of MPS IVA are caused by disruption of the cartilage and its extracellular matrix, leading to a growth imbalance. Enzyme replacement therapy (ERT) with recombinant human GALNS has yielded positive results in activity of daily living and endurance tests. However, no data have demonstrated improvements in bone lesions and bone grow thin MPS IVA after ERT, and there is no correlation between therapeutic efficacy and urine levels of keratan sulfate, which accumulates in MPS IVA patients. Using qualitative and quantitative proteomics approaches, we analyzed leukocyte samples from healthy controls (n = 6) and from untreated (n = 5) and ERT-treated (n = 8, sampled before and after treatment) MPS IVA patients to identify potential biomarkers of disease. Out of 690 proteins identified in leukocytes, we selected a group of proteins that were dysregulated in MPS IVA patients with ERT. From these, we identified four potential protein biomarkers, all of which may influence bone and cartilage metabolism: lactotransferrin, coronin 1A, neutral alpha-glucosidase AB, and vitronectin. Further studies of cartilage and bone alterations in MPS IVA will be required to verify the validity of these proteins as potential biomarkers of MPS IVAS
