La educación social y la web 2.0: Nuevos espacios de innovación e interacción social en el Espacio Europeo de Educación Superior

La Educación Social en el Espacio Europeo de Educación Superior (EEES) requiere de nuevos procesos de enseñanza y aprendizaje para ubicarse en el escenario del desarrollo de la sociedad del conocimiento y la información. Para ello, las Tecnologías de la Información y la Comunicación (TICs), y especialmente las prácticas formativas de corte socio-constructivista e investigador que utilicen aplicaciones web 2.0, jugarán un papel muy significativo en la innovación y la mejora de la Educación Social. El presente trabajo realiza una aproximación conceptual al concepto de web 2.0 y analiza las implicaciones didácticas de la segunda generación web en el proceso de convergencia con Europa en materia de Educación Superior.Social Education at European Higher Education Area requires new teaching and learning processes to be located on the knowledge and information society scene. For that purpose, Information and Communication Technologies (ICT) - especially social-constructivism and researcher formative practices using web 2.0 applications- will play a significant role in the innovation and improvement Social Education. This article analyzes didactic implications through a conceptual approximation about web 2.0 and the second generation in the convergence process with Europe in terms on Higher Education

Diseño e implementación del kernel de xDEVS, versión distribuida

Para entender nuestro proyecto, debemos comprender DEVS. Dentro de los formalismos más populares de representación de sistemas de eventos discretos se encuentra DES. En la década de los 70, el matemático Bernard Zeigler propuso un formalismo general para la representación de dichos sistemas. Este formalismo denominado DEVS (Discrete EVent System Specification) es el formalismo más general para el tratamiento de DES. DEVS permite representar todos aquellos sistemas cuyo comportamiento pueda describirse mediante una secuencia de eventos discretos. Estos eventos se caracterizan por un tiempo base en el que solo un número de eventos finitos puede ocurrir. DEVS Modelado y Simulación tiene múltiples implementaciones en varios lenguajes de programación como por ejemplo en Java, C# o C++. Pero surge la necesidad de implementar una plataforma distribuida estable para proporcionar la mecánica de interoperabilidad e integrar modelos DEVS diversificados. En este proyecto, se nos dará como código base el core de xDEVS en java, aplicado de forma secuencial y paralelizada. Nuestro trabajo será implementar el core de manera distribuida de tal forma que se pueda dividir un sistema DEVS en diversas máquinas. Para esto hemos utilizado sockets de java para hacer la transmisión de datos lo más eficiente posible. En un principio deberemos especificar el número de máquinas que se conectarán al servidor. Una vez estas se hayan conectado se les enviará el trabajo específico que deberán simular. Cabe destacar que hay dos formas de dividir un sistema DEVS las cuales están implementadas en nuestro proyecto. La primera es dividirlo en módulos atómicos los cuales son subsistemas indivisibles en un sistema DEVS. Y la segunda es dividir las funciones de todos los subsistemas en grupos y repartirlos entre las máquinas. En resumen el funcionamiento de nuestro sistema distribuido será comenzar ejecutando el trabajo asignado al primer cliente, una vez finalizado actualizará la información del servidor y este mandara la orden al siguiente y así sucesivamente

Machine learning screening tools for the prediction of extraction yields of pharmaceutical compounds from wastewaters

Pharmaceutical compounds have become an increasingly important source of pollutants in wastewaters being conventional treatments ineffective in removing them, so they are commonly discharged into the environment. Pharmaceuticals can be successfully removed using liquid-liquid extraction, and COSMO-RS can be used to predict interactions and identify the most promising solvents. However, COSMOtherm models cannot account for key process parameters, which reduces the accuracy of these computational models. Therefore, there is a need for alternative computational approaches to accurately predict the extraction yields of pharmaceuticals which can incorporate both processing and interaction variables. This work used machine learning to predict the extraction yield of eleven pharmaceuticals using eight solvents. Six regression models and two classification models were explored. The best performance was obtained with ANN regressor (test MAE: 4.510, test R2: 0.884) and RF classifier (test accuracy: 0.938, test recall: 0.974). The RF regression analysis and classification also showed key extraction yield features: solvent-to-feed ratio, n–octanol–water partition coefficient, hydrogen bond and Van der Waals contributions to excess enthalpy, and pH distance to nearest pKa. Machine learning showed as an excellent tool for screening and selecting the most promising solvents and process conditions to remove pharmaceuticals from wastewater.This work was supported by Comunidad Autónoma de Madrid [project numbers P2018/EMT-4341 and PR65/19-22441].

Interface electronic system for measuring air acidity with optical sensors

Environmental acidity is a key parameter in Cultural Heritage conservation issues since it has a direct impact on degradation of both exposed and stored materials. Unfortunately, most of the acidity sensors now available are electrodes, which are not able to measure pH in gaseous phases and, therefore, are not suitable for measuring the environmental acidity of the air. This paper describes the development of an interface electronic system designed for the practical application and using of environmental acidity sensors prepared by the Sol–Gel procedure. These chemical sensors were investigated previously. They have optical response: their color changes reversibly depending on the pH of the surrounding environment (air). A simple portable unit with a wireless ZigBee interface has been designed and developed to measure the environmental acidity in museums, showcases, store and exhibition rooms and several Cultural Heritage buildings. Main achievements of the interface electronic system have focused, on the one hand, on conversion of the optical signal of sensors into an electric current and, on the other hand, on the computer interfacing to obtain quantitative data of environmental pH. Quantitative data are obtained through the calibration curve of sensors and the software designed for managing the whole system.The authors acknowledge partial funding of programs: Geomateriales (ref.

Indocyanine green angiography-guided thyroidectomy versus conventional thyroidectomy for preserving parathyroid function: study protocol for a randomized single-blind controlled trial

Introduction: Angiography with indocyanine green (ICG) fluorescence performed before thyroidectomy would allow identification of the vascularization of parathyroid glands, maximizing efforts for preserving functioning glands intraoperatively. The rationale of the study was based on the hypothesis that showing the vascular pattern of the parathyroid glands by means of ICG angiography before performing the thyroidectomy could prevent permanent hypoparathyroidism. Methods and analysis: We propose a randomized single-blind controlled and multicenter clinical trial to assess the efficacy and safety of ICG angiography-guided thyroidectomy to identify the vascular pattern of the parathyroid glands versus conventional thyroidectomy in patients scheduled for elective total thyroidectomy. Patients will be randomized 1:1 to ICG angiography-guided thyroidectomy (experimental group) or conventional thyroidectomy (control group). Patients in the experimental group will undergo ICG angiography before thyroidectomy to identify the feeding vessels of the parathyroid glands and then, post-thyroidectomy ICG angiography to predict immediate parathyroid gland function by scoring the degree of fluorescence of the glands. Patients in the control group will undergo post-thyroidectomy ICG angiography only. The primary outcome measure will be the rate of patients with permanent hypoparathyroidism. Secondary outcome measures will be rate of postoperative hypoparathyroidism, the percentage of well vascularized parathyroid glands remaining in situ, the levels of iPTH and serum calcium after surgery and the influence of the type of vascular pattern of the parathyroid glands over these outcomes, as well as the safety profile of ICG angiography. Discussion: The results will contribute to adopt a new surgical strategy based on intraoperative ICG angiography before performing total thyroidectomy, according to which the rate of permanent hypoparathyroidism could be substantially reduced
