Interaction/Predictive Tools/Dashboard/Evaluation Learning Process/Automated Process/eLearning Environment/Learning Environment/Learning Management System (LMS)/Cloud Computing/ Learning Performance, and Learning Analytics. The purpose of this study was the initial step in providing a clear understanding of the use of a predictive tool (dashboard) to improving the learning process in the higher education field. Through further applications and research, the predictive tool must be refined to increase accuracy, and provide expeditious, reliable feedback about the students’ progress in an online environment. This information will benefit e-learning facilitators in the following ways: 1) knowing their students and, therefore, identifying how best to deliver content to them; 2) applying the right predictive tool to capitalizing on the new experience and new opportunity; 3) taking value-added approaches to student engagement; 4) bridging connections in a precise manner between enriched content and e-learning; and 5) transforming e-learning into digital experience

Design and Development of RC Railed Robot for Coffee Nursery Logistics

The Remote Controlled (RC) Railed Robot was designed and developed to transfer polybags from manual operation to an automated logistic system. Gizduino microcontroller was used to read and interpret commands sent and received by the transceivers to the robot and a remote to command instructions to the robot.The project was tested and evaluated at the Coffee Nursery of Cavite State University by determining the speed of the robot, the effectiveness of the remote control and the accuracy of the robot to lift a pallet and place it into an empty space.Results showed that the robot was able to receive and interpret commands provided by the remote control as well as perform the tasks successfully.The most significant recommendation was to use a counterweight at the rear side of the robot to avoid unnecessary derailments of the robot if lifting heavier or greater number of pallets is desired

A further study of the kinetics of recrystallization and grain growth of cold rolled TWIP steel

Over last decades, the twinning - induced plasticity Fe-Mn-C (TWIP) steels have been the focus on huge amount of research works due to their prominent strength – ductility compounding which develops from the occurrence of extended mechanical twinning during plastic deformation under mechanical loads (Grässel and Frommeyer, 1998; Frommeyer et al., 2000; Cornette et al., 2005; Scott et al., 2006; Bouaziz et al., 2008; Hamada et al., 2010; Bouaziz et al., 2011; De Cooman et al., 2011; Galán et al., 2012; Gil Sevillano and De las Cuevas, 2012; Chen et al., 2013; De las Cuevas et al., 2014; Ghasri-Khouzani and McDermid, 2015; Pierce et al., 2015; De las Cuevas and Gil Sevillano, 2017). In TWIP steels, the fully austenitic microstructure can be retained by means of high level alloying with elements such as Mn, Al and Si. Al and Si are mainly used to adjust the magnitude of the stacking fault energy, gSFE, of austenite (Frommeyer et al., 2000). Furthermore, they also strengthen the steel by solid solution hardening and stabilize austenite owing to their ability of slowing down the precipitation of carbides, especially cementite, leaving more carbon available for the enrichment of austenite (Leslie and Rauch, 1978)

Dispensación de benzodiacepinas y análogos en farmacias comunitarias de Valladolid

Introducción: Las benzodiacepinas (BZD) son fármacos de consumo creciente, que se utilizan muy frecuentemente para los trastornos de ansiedad y del sueño, así como relajantes musculares. Muchos pacientes las usan de forma crónica a pesar de estar desaconsejadas y, en algunas ocasiones, de manera inadecuada, en especial la población anciana. Objetivos: Investigar las principales características de los usuarios, las BZD prescritas, si se tiene conocimiento y se hace un buen uso de ellas, las reacciones adversas, las posibles interacciones farmacológicas con la medicación y otros problemas relacionados con los medicamentos. Material y métodos: Se llevó a cabo un estudio transversal en 2 farmacias comunitarias de Valladolid desde septiembre de 2012 hasta febrero de 2013. Se utilizó un cuestionario cerrado y administrado por el farmacéutico. Se incluyeron todos los pacientes mayores de 16 años que solicitaron BZD prescritas por el médico. Resultados: En total, 104 pacientes consintieron ser entrevistados. La mayor parte utilizaba las BZD más tiempo del aconsejado. El 63,5% de los pacientes experimentó, al menos, una reacción adversa (dependencia, sedación, somnolencia, pérdida de memoria, etc.). El 13,2% de los usuarios mayores de 65 años estaba tomando dosis mayores de las recomendadas en la ficha técnica, y el 27,7% de éstos utilizaba BZD de vida media larga. Conclusiones: Este estudio muestra un inadecuado uso de las BZD por parte de la población, en especial los ancianos. El farmacéutico comunitario junto con el médico desempeñan un papel clave en la mejora del uso de las BZD por parte de la población

Principios de manejo de control quimico del tizon tardio de la papa en Ecuador.

Es necesario establecer con claridad los principios del manejo químico de la enfermedad antes que recomendaciones explícitas del uso de fungicidas. Para establecer los principios de manejo, a su vez es necesario conocer la eficacia de control y los riesgos de resistencia de los patógenos a los fungicidas. Considerando que la base del control de la enfermedad es la rotación de fungicidas, posibles sinergias y antagonismos deben ser establecidos. Además, los niveles globales de toxicidad deben ser bajos y la eficacia alta; todos estos aspectos deben ser considerados para establecer los principios de manejo del control químico. Con estos antecedentes, estudios de eficacia, resistencia del patógeno a los fungicidas, rotación de fungicidas han permitido identificar los principios de manejo del tizón tardío, lo que permitirá el manejo sustentable de la enfermedad

A proteomics study of chilling injury in tomato fruit, a low-temperature stress-induced physiological disorder affecting fruit quality

Trabajo presentado a la conferencia "Molecular Basis of Plant Stress" celebrado en Bulgaria del 21 al 23 de septiembre de 2011.-- FP7 REGPOT Project "BioSupport".Tomato (Solanum lycopersicum L.) is the second most cultivated horticultural crop in the world in terms of harvested area and production, after the potato (FAOSTAT 2011, data from 2009). A main problem regarding its postharvest life is its sensitivity to low temperature stress during refrigerated storage, which constitutes a main obstacle for its long-term commercialization. This sensitivity is reflected in the physiopathy of chilling injury (CI), which negatively affects the final fruit quality. The main symptoms of CI-affected fruits are skin depressions, tissue decomposition and impaired ripening, which results in deficient flavour and aroma. Physiological and biochemical events involved in CI progress have been extensively described, but the precise molecular mechanisms that ultimately regulate the plant response to cold stress remain unclear. In order to investigate this response at molecular level in tomato fruit a proteomics strategy has undertaken. The proteome analysis provides a direct insight on the changes undergone by proteins, which are the major functional determinants of the cell machinery, in a certain biological situation such as low temperature stress. The protein expression profile of chilled tomato fruits has been compared with fruits stored at nonchilling temperature (control). The protein analysis has been performed by two-dimensional differential-in-gel-electrophoresis (2D-DIGE), and mass spectrometry of protein spots was applied to identify proteins differentially expressed. Comparative analysis revealed significant changes in abundance of 31 identified proteins between the proteomes of chilled and control fruits. Major modifications in the expression profile are related to those proteins specifically involved in stress (chaperonins and heat-shock proteins); cell wall biochemistry (hydrolytic enzymes), and carbohydrate metabolism (enzymes involved in glycolisis, tricarboxylic acids cycle, photosynthesis and sucrose biosynthesis).This work was supported by the Spanish Ministry of Science and Innovation (MICINN) through grant and PIE2009-40I080, and by the Council of Science and Technology from the Spanish Region of Murcia (Fundación SENECA) through grant no. 04553/GERM/06.Peer Reviewe

Vibrational, non-adiabatic and isotopic effects in the dynamics of the H2 + H2+ → H3+ + H reaction: application to plasma modelling

The title reaction is studied using a quasi-classical trajectory method for collision energies between 0.1 meV and 10 eV, considering the vibrational excitation of (Formula presented.) reactant. A new potential energy surface is developed based on a Neural Network many body correction of a triatomics-in-molecules potential, which significantly improves the accuracy of the potential up to energies of 17 eV, higher than in other previous fits. The effect of the fit accuracy and the non-adiabatic transitions on the dynamics are analysed in detail. The reaction cross section for collision energies above 1 eV increases significantly with the increasing of the vibrational excitation of (Formula presented.) ((Formula presented.)), for values up to (Formula presented.) =6. The total reaction cross section (including the double fragmentation channel) obtained for (Formula presented.) =6 matches the new experimental results obtained by Savic, Schlemmer and Gerlich [Chem. Phys. Chem. 21 (13), 1429.1435 (2020). doi:10.1002/cphc.v21.13]. The differences among several experimental setups, for collision energies above 1 eV, showing cross sections scattered/dispersed over a rather wide interval, can be explained by the differences in the vibrational excitations obtained in the formation of (Formula presented.) reactants. On the contrary, for collision energies below 1 eV, the cross section is determined by the long range behaviour of the potential and do not depend strongly on the vibrational state of (Formula presented.). In addition in this study, the calculated reaction cross sections are used in a plasma model and compared with previous results. We conclude that the efficiency of the formation of (Formula presented.) in the plasma is affected by the potential energy surface use

Effect of Zeolitic Imidazolate Framework Topology on the Purification of Hydrogen from Coke Oven Gas

This work aims to shed light on the performance of zeolitic imidazolate frameworks for hydrogen purification from coke oven gases (COG). Using molecular simulation, we model COG as a mixture of six gases and study the effect of ZIF topology on the separation performance. To do this, we compare similar structures, e.g., ZIF-8 and ZIF-11, and focus on obtaining information that explains why they behave differently while being so similar. Simulation results show that the structure with the smallest pore size best separates hydrogen from carbon monoxide and nonpolar molecules. The adsorption of carbon dioxide is also strongly affected by the polarizability of the structure. However, the adsorption of the other components (methane, carbon monoxide, nitrogen, and oxygen) is strongly dependent on their pore size. We also provide molecular information on the effect of phase transition on hydrogen purification using ZIF-7 as an example, which drastically changes the pore volume of the structure when it changes phase. These findings will help to select high-performance ZIFs for adsorption- or screening-based hydrogen purification.</p
