Propiedades psicométricas de la Escala de Victimización Escolar entre Iguales (VE-I)
2018
<p>La violencia escolar entre iguales tiene graves consecuencias para las víctimas. La victimización puede ser directa, mediante agresiones físicas y verbales, y relacional mediante exclusión y rechazo social. El objetivo de este estudio fue analizar las propiedades psicométricas de la escala de Victimización Escolar entre Iguales (VE-I) que consta de 11 ítems relativos a diferentes formas de victimización. En este estudio participaron 1389 adolescentes (50.45% varones), de entre 11 y 15 años (M = 13.37, DE = 1.23). La estructura de la escala fue analizada mediante análisis factorial exploratorio y análisis factorial confirmatorio, por lo que se utilizaron dos submuestras diferentes.…
Effect of Integrating Photovoltaic Systems on Electrical Network Losses Considering Load Variation
2018
Planning of Distributed Generation (DG) units in the power distribution networks is an important issue, one of the most important considerations that is directly affected by installing DG units is the power losses. Improper allocation of DG units to the grid can lead to a noticeable increase in the power losses. Moreover, the load variation is considered as critical matter when studying the optimal scenario that minimizes the power losses in the network. The aim of this paper is to investigate the effect of integrating photovoltaic (PV) units on the distribution network losses considering load variation. The optimal parameters of the DG units were calculated for the various load demands in …
Contribution of bacterial biodiversity on the operational performance of a styrene biotrickling filter.
2020
Abstract Long-term operational stability of biotrickling filters (BTFs) degrading volatile organic compounds (VOCs) is dependent on both physicochemical as well as biological properties. Effects of increasingly stressful levels of air pollutants on the microbial structure of biofilms within BTFs are not well understood, especially for VOCs such as styrene. To investigate the relationship between biofilm biodiversity and operational stability, the temporal dynamics of a biofilm from a biotrickling filter subjected to stepwise increasing levels of air polluted with styrene was investigated using 16S rDNA pyrosequencing and PCR-denaturing gradient gel electrophoresis (PCR-DGGE). As styrene con…
Estructura factorial del Teacher Interpersonal Self-Efficacy Scale en docentes dominicanos: ¿uno o tres factores?
2017
<p>La autoeficacia docente se define como la creencia específica acerca de la externalidad o internalidad del control de las actividades que realiza el profesor en su trabajo. El objetivo del presente estudio es contribuir a entender las propiedades psicométricas de la escala ‘Teacher Interpersonal Self-Efficacy Scale’ en una muestra de docentes de República Dominicana. Se pusieron a prueba los modelos factoriales propuestos en la literatura mediante análisis factorial confirmatorio: a) un único factor de autoeficacia; b) dos factores de autoeficacia percibida: en la gestión del aula y en la obtención de apoyo; y c) tres factores de autoeficacia percibida: en la gestión del aula, en l…

Effect of surface finish on the mechanical behaviour of Dacron© 360 woven
2013
Abstract In the present paper some experimental analyses of Dacron© 360 woven with and without surface treatment are presented to evaluate the effect of this treatment on the constitutive behaviour. This woven, widely adopted in sail manufacturing, is obtained by weaving polyethylene terephthalate (PET) yarn and it shows some peculiar features due to the manufacturing process. The experimental tensile tests, clearly show the orthotropy behaviour of the material. The effect of the treatment results in a stiffer behaviour especially along the warp and bias direction and in an increment of ultimate strength in all directions.
Wastewater treatment and reclamation : A review of pulp and paper industry practices and opportunities
2016
The pulp and paper (P&P) industry worldwide has achieved substantial progress in treating both process water and wastewater, thus limiting the discharge of pollutants to receiving waters. This review covers a variety of wastewater treatment methods, which provide P&P companies with cost-effective ways to limit the release of biological or chemical oxygen demand, toxicity, solids, color, and other indicators of pollutant load. Conventional wastewater treatment systems, often comprising primary clarification followed by activated sludge processes, have been widely implemented in the P&P industry. Higher levels of pollutant removal can be achieved by supplementary treatments, which…
A Renewable Energy mix to Supply the Balearic Islands: Sea Wave, Wind and Solar
2018
The paper investigates the status of the electrical energy sector in the Balearic Islands (Spain). In order to improve the energetic sustainability, this work analysis the availability of renewable energy sources, focusing the attention on sea wave, wind and solar. For the utilization of sea wave source, an innovative device is proposed.
