Experimental validation for the application of the flat jack test in cob walls
No full textThe flat jack test is one of the most applied investigation techniques in the field of cultural heritage conservation. The purpose of the experimental campaign presented in this paper was to assess the feasibility of the technique to measure the average compressive levels of stress in existing cob walls and determine their mechanical properties. It was observed that the single flat jack test tended to overestimate the average value of stress by a factor of two. Therefore, it is advised to apply a value of Ke 1⁄4 0:51 to correct the average compressive stress values obtained with the use of this technique
Numerical Modeling of Cob’s Nonlinear Monotonic Structural Behavior
No full textIt has been observed by performing simple and diagonal compression tests of cob wallettes
that the structural behavior of cob is highly nonlinear. This paper presents the results
obtained of the simulation of cob’s nonlinear monotonic behavior using two well-known
finite element commercial packages. Pros and cons of different available constitutive
material models are identified and discussed. Concrete (CONCR) and Concrete Damaged
Plasticity (CDP) are considered as the constitutive material models that provide the
more satisfactory results reproducing cob’s nonlinear monotonic behavior when using
ANSYS and ABAQUS, respectively
The blind spots of secularization
No full textAccording to several international surveys Spain is among the western countries with the most negative views of Jews. While quantitative data on the topic accumulates, there is a significant lack of interpretative approaches that might explain the particular Spanish case. This paper presents the background, methodology and major results of a discussion group-based study on antisemitism, which was conducted in Spain in the autumn of 2009. The study identifies and locates in different socio-economic and ideological milieus the range of stereotypical discourses on Jews, Judaism and the Arab–Israeli conflict in Spain. Analysis of the group meetings shows that, despite growing secularization in Spanish society, the central explanatory variable for persisting and resurging antisemitism in this country is still religion in a broad cultural sense.N

No full textDetecting pathogens and mounting immune responses upon infection is crucial for animal health. However, these responses come at a high metabolic price (McKean and Lazzaro, 2011, Kominsky et al., 2010), and avoiding pathogens before infection may be advantageous. The bacterial endotoxins lipopolysaccharides (LPS) are important immune system infection cues (Abbas et al., 2014), but it remains unknown whether animals possess sensory mechanisms to detect them prior to infection. Here we show that Drosophila melanogaster display strong aversive responses to LPS and that gustatory neurons expressing Gr66a bitter receptors mediate avoidance of LPS in feeding and egg laying assays. We found the expression of the chemosensory cation channel dTRPA1 in these cells to be necessary and sufficient for LPS avoidance. Furthermore, LPS stimulates Drosophila neurons in a TRPA1-dependent manner and activates exogenous dTRPA1 channels in human cells. Our findings demonstrate that flies detect bacterial endotoxins via a gustatory pathway through TRPA1 activation as conserved molecular mechanism.sponsorship: Vlaams Instituut voor Biotechnologie Alessia Soldano Luis Franco Guangda Liu Natalia Mora Emre Yaksi Bassem A Hassanr Fonds Wetenschappelijk Onderzoek G.0702.12 Alessia Soldano Yeranddy A Alpizar Brett Boonen Alejandro Lopez-Requena Natalia Mora Thomas Voets Rudi Vennekens Bassem A Hassan Karel Talaverar Fonds Wetenschappelijk Onderzoek G.0077.15 Alessia Soldano Yeranddy A Alpizar Brett Boonen Alejandro Lopez-Requena Natalia Mora Thomas Voets Rudi Vennekens Bassem A Hassan Karel Talaverar Fonds Wetenschappelijk Onderzoek G.0680.10 Alessia Soldano Yeranddy A Alpizar Brett Boonen Alejandro Lopez-Requena Natalia Mora Thomas Voets Rudi Vennekens Bassem A Hassan Karel Talaverar Fonds Wetenschappelijk Onderzoek G.0681.10 Alessia Soldano Yeranddy A Alpizar Brett Boonen Alejandro Lopez-Requena Natalia Mora Thomas Voets Rudi Vennekens Bassem A Hassan Karel Talaverar Fonds Wetenschappelijk Onderzoek G.0503.12 Alessia Soldano Yeranddy A Alpizar Brett Boonen Alejandro Lopez-Requena Natalia Mora Thomas Voets Rudi Vennekens Bassem A Hassan Karel Talaverar Fonds Wetenschappelijk Onderzoek G.0654.15 Alessia Soldano Yeranddy A Alpizar Brett Boonen Alejandro Lopez-Requena Natalia Mora Thomas Voets Rudi Vennekens Bassem A Hassan Karel Talaverar Fonds Wetenschappelijk Onderzoek G.0761.10N Alessia Soldano Yeranddy A Alpizar Brett Boonen Alejandro Lopez-Requena Natalia Mora Thomas Voets Rudi Vennekens Bassem A Hassan Karel Talaverar Fonds Wetenschappelijk Onderzoek G.0596.12 Alessia Soldano Yeranddy A Alpizar Brett Boonen Alejandro Lopez-Requena Natalia Mora Thomas Voets Rudi Vennekens Bassem A Hassan Karel Talaverar Fonds Wetenschappelijk Onderzoek G.0565.07 Alessia Soldano Yeranddy A Alpizar Brett Boonen Alejandro Lopez-Requena Natalia Mora Thomas Voets Rudi Vennekens Bassem A Hassan Karel Talaverar KU Leuven GOA/14/011 Alessia Soldano Yeranddy A Alpizar Brett Boonen Luis Franco Alejandro Lopez-Requena Guangda Liu Natalia Mora Emre Yaksi Thomas Voets Rudi Vennekens Bassem A Hassan Karel Talaverar European Commission IUAP P7/13 Alessia Soldano Yeranddy A Alpizar Brett Boonen Luis Franco Alejandro Lopez-Requena Guangda Liu Natalia Mora Emre Yaksi Thomas Voets Rudi Vennekensr KU Leuven OT/12/091 Alessia Soldano Yeranddy A Alpizar Brett Boonen Luis Franco Alejandro Lopez-Requena Guangda Liu Natalia Mora Emre Yaksi Thomas Voets Rudi Vennekens Bassem A Hassan Karel Talaverar KU Leuven PF-TRPLe Alessia Soldano Yeranddy A Alpizar Brett Boonen Luis Franco Alejandro Lopez-Requena Guangda Liu Natalia Mora Emre Yaksi Thomas Voets Rudi Vennekens Bassem A Hassan Karel Talavera (Vlaams Instituut voor Biotechnologie, Fonds Wetenschappelijk Onderzoek|G.0702.12, Fonds Wetenschappelijk Onderzoek|G.0077.15, Fonds Wetenschappelijk Onderzoek|G.0680.10, Fonds Wetenschappelijk Onderzoek|G.0681.10, Fonds Wetenschappelijk Onderzoek|G.0503.12, Fonds Wetenschappelijk Onderzoek|G.0654.15, Fonds Wetenschappelijk Onderzoek|G.0761.10N, Fonds Wetenschappelijk Onderzoek|G.0596.12, KU Leuven|GOA/14/011, KU Leuven|OT/12/091, European Commission|IUAP P7/13, KU Leuven PF-TRPLe)status: Publishe
Alma, impulso y movimiento según Alejandro de Afrodisia
No full textthis paper discusses Alexander of Aphrodisias’ conception of the soul, paying special attention to a specific aspect distinguishing the Alexandrian view from the Aristotelian one: the impulsive capacity or faculty. Firstly, it considers Alexander’s reformulation of Aristotle’s approach to the soul (as a form of the body), a reformulation that is performed in connection with his original reconstruction of hilemorphism. At this point the author makes a special emphasis upon the manner Alexander develops a ‘terraced model’ of hilemorphic composition. Secondly, the treatment of impulsive faculty, with a special focus on the theoretical performance that Alexander derives from taking the notion of impulse, is developed. Finally, Alexander’s reformulation of the Aristotelian psychology of action is also brie y considered in order to account for the sequence of the process of the production of voluntary movement and of action. This is an explicative model that leaves aside the Aristotelian resource to the structure of the practical syllogism, and incorporates the elements predominantly characteristic of the Stoic conception. This, though, does not entail the abandonment of the basic thesis of Aristotle’s stance regarding motivation, as an opposition to socratic intellectualism: the thesis of the primacy of desire, in all its possible ways, as a factor accounting for the origin of voluntary movement and action.Este artículo se ocupa de la concepción del alma elaborada por Alejandro de Afrodisia, con especial atención a un aspecto específico que la distingue de la concepción aristotélica: la introducción de una facultad o capacidad impulsiva. En primer lugar, se considera la reformulación de la concepción jaristotélica del alma como forma del cuerpo que Alejandro lleva a cabo, en conexión con su original reconstrucción del hilemorfismo. Aquí se pone especial énfasis en el modo en el cual Alejandro construye lo que puede llamarse un “modelo escalonado” de composición hilemórfica. En segundo lugar, se considera el tratamiento de la facultad impulsiva, atendiendo especialmente al rendimiento teórico que extrae Alejandro de la adopción de la noción de impulso. Por último, se considera brevemente el modelo reformulado de psicología de la acción que elabora Alejandro, para dar cuenta de la secuencia del proceso de producción del movimiento voluntario y la acción. Se trata de un modelo explicativo que deja de lado el recurso aristotélico a la estructura del silogismo práctico e incorpora, en cambio, los elementos más característicos de la concepción estoica. Ello no implica, sin embargo, el abandono de la tesis básica de la concepción aristotélica de la motivación, por oposición al intelectualismo socrático, a saber: la tesis de la primacía del deseo, en todas sus posibles formas, como factor que da cuenta del origen del movimiento voluntario y la acción

A limit analysis approach to the assessment of masonry arch structures under the influence of fundamental parameters
No full textThe majority of buildings in the world are made of masonry, and some of these buildings are historical constructions with heritage values. It is commonly known that masonry can withstand significant compressive stresses, but since it lacks tensile strength, it is more susceptible to dynamic actions. In this aspect a curvature was introduced in masonry constructions in order to reduce the tensile stresses and exploit their compressive strength. This innovative structural element in the past enabled crossing large spans without intermediate supports at the cost of a horizontal thrust transmitted to the supports. The structural condition of the supports constructed of masonry is of crucial importance to resist this horizontal force that varies in intensity based on the type of curvature of the arch. Additionally, a non-standard approach including joint friction has shown to be important in such structures and therefore sliding mechanisms are investigated. Research on critical parameters affecting the safety levels of piers under the thrust of arches is carried out using an in-house code (ALMA) that uses limit analysis as a rigid block approach to modeling masonry with frictional joints. Under two cases of vertical live load, symmetric and asymmetric, the different pier textures, levels of joint friction and arch shallowness, were examined. The main outcomes of the study demonstrate that even before initiating any expensive testing campaign, complex structural analysis, the investigation of these parameters in the structure itself present the most important features of its safety level and vulnerability.Presented at the 11th International Civil Engineering, Infrastructure and Environment Conference (IC-CEIE) 2022, Kosovo
