Microcellular Foaming of Polymethylmethacrylate in a Batch Supercritical CO2 Process: Effect of Microstructure on Compression Behavior
Microcellular foaming of reinforced core/ shell Polymethylmethacrylate (PMMA) was carried out bymeans of supercritical CO2 in a single-step process. Samples were produced using a technique based on the saturation of the polymer under high pressure of CO2(300 bars,40 C), and cellular structure was controlled by varying the depressurization rate from 0.5 bar/s to 1.6 x10-2 bar/sleading to cell sizes from 1lm to 200l m, and densities from 0.8 to 1.0 g/cm3. It was found that the key parameter to control cell size was depressurization rate, and larger depressurization rates generated bigger cell sizes. On the other hand, variation of the density of the samples was not so considerable. Low rate compression tests were carried out, analyzing the dependence of mechanical parameters such as elastic modulus, yield stress and densification strain with cell size. Moreover, the calculation of the energy absorbed for each sample is presented, showing an optimum of energy absorption up to 50% of deformation in the micrometer cellular range (here at a cell size of about 5 µm). To conclude, a brief comparison between neat PMMA and the core/shell reinforced PMMA has been carried out, analyzing the effect of the core/shell particles in the foaming behavior and mechanical properties
“Teoría General del Contrato y Protección de Consumidores”
El objetivo que se busca es conocer la evolución del Derecho de consumo y examinar
las particularidades que se han introducido en la Teoría General del Contrato (contenida
en el Código Civil) con el fin de proteger a los consumidores, estudiándose por un lado,
la aplicación de la normativa general que regula las condiciones generales de la
contratación, y por otro, la normativa específica del derecho de consumo, con el fin de
ver en qué aspectos únicamente se aplica la general y en que otros aspectos se aplica la
específica, mejorando lo dispuesto por la general, ver en qué grados y las consecuencias
de la aplicación de esta normativa.Grado en Relaciones Laborales y Recursos Humano
Mujer y magia en el mundo romano occidental: la imagen femenina en las tabellae defixionum eróticas
Este trabajo pretende analizar la participación de las mujeres en época romana en los ritos mágicos en relación con la magia amatoria. Para ello analizaremos una de las fuentes primarias para el conocimiento de las prácticas mágicas en el mundo antiguo, las tablillas de maldición, las tabellae defixionum. Con este estudio se busca, por tanto, deslegitimar la visión tradición de las mujeres como únicas consumidoras de la magia amorosa, observándose una gran variedad de géneros en relación al rito de las defixionesThe objective of this paper is to analyze the participation of women in Ancient Rome and its magical rites connected to love magic. We will analyze one of the primary sources for the study of magical practice in the Ancient World, the curse tablets, the tabellae defixionum. The aim of this research is to undermine the traditional view of women as unique consumers of erotic magic showing a wide variety of gender in relation to the rite of the defixione
Analysis of predictive thermodynamic models for estimation of polycyclic aromatic solid solubility in hot pressurized water
This is an open access article licensed under the terms of the Creative Commons Attribution Non-Commercial License.The ability of two thermodynamic approaches to predict the solubility of solid compounds in hot pressurized water is studied and compared. The Regular Solution Theory, based on the solubility parameter concept, and UNIFACbased models were applied to calculate the solute activity coefficient and then, solubility predictions were compared with experimental data reported in the literature. The analysis was carried out considering polycyclic aromatic hydrocarbons as model substances, i.e. substances which contain only the aromatic AC and ACH groups, and for which reliable pure physical properties such as melting point, fusion enthalpy and molar volume are available in the literature. The solubility values predicted with the UNIFAC-based models were considerably better than those obtained with the solubility parameter approach. Particularly, the modified Dortmund UNIFAC model presented an appropriate functionality of solubility with temperature, and the extension of this model to other type of aromatic compounds also provided a satisfactory prediction of solubility data.This work has been financed by project S2009-AGR- 1469 from the Comunidad Autónoma de Madrid (Spain) and CSD2007-00063 FUN-CFOOD (Programa CONSOLIDERINGENIO 2010) project.Peer Reviewe
