Using Open Geographic Data to Generate Natural Language Descriptions for Hydrological Sensor Networks

Providing descriptions of isolated sensors and sensor networks in natural language, understandable by the general public, is useful to help users find relevant sensors and analyze sensor data. In this paper, we discuss the feasibility of using geographic knowledge from public databases available on the Web (such as OpenStreetMap, Geonames, or DBpedia) to automatically construct such descriptions. We present a general method that uses such information to generate sensor descriptions in natural language. The results of the evaluation of our method in a hydrologic national sensor network showed that this approach is feasible and capable of generating adequate sensor descriptions with a lower development effort compared to other approaches. In the paper we also analyze certain problems that we found in public databases (e.g., heterogeneity, non-standard use of labels, or rigid search methods) and their impact in the generation of sensor descriptions

The use of amino acid formulas in pediatric patients with allergy to cow’s milk proteins: Recommendations from a group of experts

Amino acid formula; Cow’s milk allergy; Infant formulaFórmula d'aminoàcids; Al·lèrgia a la llet de vaca; Fórmula infantilFórmula de aminoácidos; Alergia a la leche de vaca; Fórmula infantilOne of the most common food allergies in children is cow’s milk allergy (CMA). In breast-fed infants with CMA, the mother is encouraged to avoid dairy products. If this is not possible, or in formula fed infants, use of hypoallergenic replacement formulas such as extensively hydrolyzed formulas (EHF) is recommended. However, in ∼5% of patients EHFs are not tolerated and/or allergy symptoms can persist. When EHFs are ineffective and in severe forms of CMA, amino acid-based formulas (AAF) should be considered. Six pediatric gastroenterologists with extensive experience in food allergy management reviewed scientific publications and international clinical practice guidelines to provide practical recommendations on AAF. The guidelines reviewed had discrepancies and ambiguities around the specific indications for using formulas as a milk substitute. The panel recommends AAFs as the first therapeutic option in anaphylaxis due to CMA, in acute and chronic severe food protein-induced enterocolitis syndrome, in CMA associated with multiple food allergy, and in cases of eosinophilic esophagitis not responding to an extended exclusion diet or not eating solids. The main benefit of AAF is its absence of residual allergenicity, making it a safe treatment option in severe CMA patients who do not tolerate or respond to an EHF.This research was funded by Nutricia to support the face-to-face and online meetings

A second-order cone programming reformulation of the economic dispatch problem of bess for apparent power compensation in ac distribution networks

The problem associated with economic dispatch of battery energy storage systems (BESSs) in alternating current (AC) distribution networks is addressed in this paper through convex optimization. The exact nonlinear programming model that represents the economic dispatch problem is transformed into a second-order cone programming (SOCP) model, thereby guaranteeing the global optimal solution-finding due to the conic (i.e., convex) structure of the solution space. The proposed economic dispatch model of the BESS considers the possibility of injecting/absorbing active and reactive power, in turn, enabling the dynamical apparent power compensation in the distribution network. A basic control design based on passivity-based control theory is introduced in order to show the possibility of independently controlling both powers (i.e., active and reactive). The computational validation of the proposed SOCP model in a medium-voltage test feeder composed of 33 nodes demonstrates the efficiency of convex optimization for solving nonlinear programming models via conic approximations. All numerical validations have been carried out in the general algebraic modeling system.Fil: Montoya Giraldo, Oscar Danilo. Universidad Distrital Francisco José de Caldas; Colombia.

Simultaneous Minimization of Energy Losses and Greenhouse Gas Emissions in AC Distribution Networks Using BESS

The problem of the optimal operation of battery energy storage systems (BESSs) in AC grids is addressed in this paper from the point of view of multi-objective optimization. A nonlinear programming (NLP) model is presented to minimize the total emissions of contaminant gasses to the atmosphere and costs of daily energy losses simultaneously, considering the AC grid complete model. The BESSs are modeled with their linear relation between the state-of-charge and the active power injection/absorption. The Pareto front for the multi-objective optimization NLP model is reached through the general algebraic modeling system, i.e., GAMS, implementing the pondered optimization approach using weighting factors for each objective function. Numerical results in the IEEE 33-bus and IEEE 69-node test feeders demonstrate the multi-objective nature of this optimization problem and the multiple possibilities that allow the grid operators to carry out an efficient operation of their distribution networks when BESS and renewable energy resources are introduced.Universidad Tecnológica de Bolíva

Immigrant Career Paths and Social Structure: The Case of Spain

This article examines the possibilities for immigrants in Spain to converge with natives around certain key aspects of work: such as stability, salaries, career advancement. The concept of the work schedule becomes crucial to seeing the extent to which immigrants have made progress or not in the process of integration and mobility from their entry into the labor market until the time the study was completed, 2007. Possible answers to this question are constructed by differentiating various groups of immigrants by country of origin, that is according to structural or individual features, making it possible to understand why some tend to converge and others do not. The itinerary gives us a dynamic picture of the phenomena, and suggests the diversification of an artificial homogeneity of immigrant groups (also, of course, of the indigenous groups) to break down widespread stereotypes

Papel del receptor S1P sobre el estrés oxidativo mitocondrial en cultivo neuronal

Introducción: Fingolimod, fármaco inmunomodulador, presenta propiedades neuroprotectoras que podrían promover la recuperación de la función cognitiva en enfermedades neurodegenerativas. El estrés oxidativo parece tener un papel fundamental en la patogénesis de dichas enfermedades, siendo la mitocondria una de las fuentes más importantes de especies reactivas de oxigeno (ROS). Objetivo: Determinar la implicación del receptor S1P en los efectos neuroprotectores mostrados por fingolimod fosfato (FP), forma activa de fingolimod, en un modelo celular de estrés oxidativo mitocondrial inducido por menadiona (Vitk3). Material y métodos: La línea celular SN4741 (70-80 % confluencia), se utilizó como control o se trató con Vitk3 15 µM en presencia o ausencia de FP 50 nM o FP 50 nM + W123 10 µM (antagonista S1P) durante 4 horas para estudiar: niveles de ROS mitocondrial según el marcaje de la producción de anión superóxido (O2−.); activación de caspasa-3; niveles de tioles totales (TTLs); marcadores mitocondriales (potencial de membrana mitocondrial-PMM-, actividad citocromo c oxidasa-COX- y consumo de oxígeno-OCR-). Las diferencias estadísticas se determinaron usando ANOVA de un factor. Resultados: W123 revierte parcialmente el efecto protector de FP sobe muerte celular programada, desencadenada por aumento de ROS (p<0,05) y consumo de reserva de antioxidante (p<0,05). El efecto de FP sobre los marcadores mitocondriales PMM, actividad COX y OCR es abolido con W123 (p<0,05). Conclusión: El receptor S1P está implicado en gran parte de los efectos protectores de FP, indicando un papel fundamental de S1P en el mantenimiento de la homeostasis mitocondrial.

Sistema de iniciación y acreditación del derecho previsional

El proyecto "Sistema de Iniciación y Acreditación del Derecho Previsional" (SIADeP) fue desarrollado por la Universidad Tecnológica Nacional - Facultad Regional Córdoba para la Caja de Jubilaciones, Pensiones y Retiros de la Provincia de Córdoba. Esta herramienta electrónica permitió sistematizar, automatizar, integrar y agilizar uno de los procesos claves de la organización, que antes se realizaba completamente en forma manual: la iniciación del trámite jubilatorio a partir de la acreditación del derecho previsional, en caso que le corresponda al ciudadano solicitante. Para ello se desarrolló un aplicativo web, cuyo objetivo es determinar si una persona solicitante tiene el derecho a acceder a una prestación, definida por ley, conforme a los requisitos y reglas de acreditación existentes en cada uno de los regímenes vigentes, para luego determinar el monto del haber inicial de la prestación solicitada. La implementación del aplicativo dio origen a un cambio en el proceso administrativo y su ejecución es actualmente clave, por cuanto permite conocer a priori la situación previsional del aportante, como así también la acreditación del beneficio. El objetivo fue cumplido y dio lugar a que la Universidad cumpla su rol social, brindando una solución informática ágil, transparente y confiable al Estado.Sociedad Argentina de Informática e Investigación Operativ

Mercury in archaeological human bone: biogenic or diagenetic?

We investigated mercury (Hg) in human bone from archaeological sites in the Iberian Peninsula where the cultural use of cinnabar (HgS) as a pigment, offering or preservative in burial practices has been documented from the 4th to 2nd millennia cal B.C. (Late Neolithic, Copper Age and Bronze Age). Previous analyses have shown high levels of total mercury (THg) in human bone at numerous Neolithic and Chalcolithic sites in this region, but the question remains if this mercury entered the bones via diagenetic processes in the soil, especially where cinnabar powder and paint was found associated with the burials, or if it entered the bone via biogenic pathways from exposure to mercury from using cinnabar in life. We analyzed the humerus, femur, and tibia from a total of 30 individual burials from four Neolithic to Bronze Age sites in Iberia and found low to high values of THg in these bones, with the humerus showing significantly more THg concentrations than other skeletal elements when the THg was greater than 1 ppm. This pattern of Hg deposition in skeletal material from different sites and ages strongly suggests a biogenic origin for the mercury. In addition, absence of detectable Hg in bones with high to low values of THg using SEM EDS analysis further discounts diagenetic intrusion of Hg or cinnabar particles into the bone from the soil. It is likely that greater stress and bone remodeling rates from use of heavy tools and other activities in life are responsible for higher THg in the humerus than other skeletal elements, but additional research is needed to verify this.National Science FoundationNational Science Foundation (NSF) [ECCS-1542174]Spanish GovernmentSpanish Government [HAR2016-78036-P, HAR2016-74846-P, HAR2017-82755-P, HAR2017-83004-P, I + D HAR2017-87324-P]CIAS [PEst-OE/SADG/UI0283/2019]FCTPortuguese Foundation for Science and Technology [PTDC/EPH-ARQ/0798/2014]info:eu-repo/semantics/publishedVersio
