Reseña

Francisco Rodríguez Adrados’ La democracia ateniense (1975) was canonical since its publication in 1966 (with a different title). The current article analyses, first, the ideological foundations of the work and, secondly, the prioritization of textual commentary and philological tools in historical analysis, that is, the textual-centrism of the book, pointing out also its accomplishments. The interpretation of our article is based in a textual as well as contextual analysis. It explores the intellectual networks and the configuration of the field of Classics in Spain in the formation of Adrados’s work. On the other hand, it reads the main sources and intertexts of La democracia ateniense, the German philology (Jaeger and Schachermeyr). The aim of this work is to understand the appropriation, limits, scope and ideological horizon of Adrados’ vision of Athenian democracy, as well as his achievements and innovations, the “scholastic creativity”. Adrados is one of the main founding fathers of Classics in Spain. La obra de Francisco Rodríguez Adrados, La democracia ateniense (1966 y 1975, segunda edición con cambios), fue canónica desde la fecha de aparición, en la segunda fase del tardofranquismo y en su edición final (1975) hacia el final de la dictadura. El presente trabajo analiza, primero, sus bases ideológicas; segundo, la priorización del comentario de textos y de las herramientas de la filología en el análisis histórico, es decir, el textocentrismo de la obra, y apunta los límites y logros del helenista español.Nuestra lectura se fundamenta en un análisis textual y contextual. Explora la elección de las fuentes principales del análisis de Adrados, el impacto de la filología e historiografía alemanas decimonónicas y de la primera mitad del XX (Jaeger, Schachermeyr), y examina su concepción de la historia, los logros, innovaciones y su lectura de la democracia ateniense, a caballo entre una visión progresista y crítica de las limitaciones de la misma, en comparación con las democracias representativas. Se considera la formación y la configuración del campo de la filología clásica en España en el franquismo en el marco de la posguerra y cómo todo ello marcó La democracia ateniense, una obra seminal surgida de una forma de escolástica creativa.

The extracellular matrix (ECM) is a network of di erent proteins and proteoglycans that controls di erentiation, migration, repair, survival, and development, and it seems that its remodeling is required for healthy adipose tissue expansion. Obesity drives an excessive lipid accumulation in adipocytes, which provokes immune cells infiltration, fibrosis (an excess of deposition of ECM components such as collagens, elastin, and fibronectin) and inflammation, considered a consequence of local hypoxia, and ultimately insulin resistance. To understand the mechanism of this process is a challenge to treat the metabolic diseases. This review is focused at identifying the putative role of ECM in adipose tissue, describing its structure and components, its main tissue receptors, and how it is a ected in obesity, and subsequently the importance of an appropriate ECM remodeling in adipose tissue expansion to prevent metabolic diseases.

The severe economic crisis that began in 2008 has encouraged the new emergence of protest parties in some European countries. The erosion of traditional politics has been capitalized by populist oriented movements: in the Italian case the Movimento 5 Stelle and in the Spanish case Podemos. The goal of this contribution is the analysis of the causes, organizational trajectories, leadership structures, social bases and ideological and programmatic issues of both parties. The M5S and Podemos have strategic and ideological differences, but share the radical criticism of the “system” which they disqualify outright., SocietàMutamentoPolitica, Vol 6, N° 11 (2015): Per comparare la crisi europea oggi: scenari di mutamento sociale e politico in Italia e in Spagna

Recent work on hyperspectral image (HSI) unmixing has addressed the use of overcomplete dictionaries by employing sparse models. In essence, this approach exploits the fact that HSI pixels can be associated with a small number of constituent pure materials. However, unlike traditional least-squares-based methods, sparsity-based techniques do not require a preselection of endmembers and are thus able to simultaneously estimate the underlying active materials along with their respective abundances. In addition, this perspective has been extended so as to exploit the spatial homogeneity of abundance vectors. As a result, these techniques have been reported to provide improved estimation accuracy. In this letter, we present an alternative approach that is able to relax, yet exploit, the assumption of spatial homogeneity by introducing a model that captures both similarities and differences between neighboring abundances. In order to validate this approach, we analyze our model using simulated as well as real hyperspectral data acquired by the HyMap sensor.

The present study provides a meteorological and bioclimatic characterisation of three Mediterranean areas: Spain, Italy and Tunisia. This includes, on the one hand, an evaluation of the past climate using meteorological data collected from 1931 to 1994. On the other hand, the future climate characterisation has been constructed for each study area, under the projected A1B emission scenario for the 2081 to 2100 period. Three Bioclimatic Indices are used to compare the annual and seasonal climate from these past periods through to these future periods: the Ombrothermic Index, the Continentality Index and the Thermicity Index. A clear tendency toward semicontinentality in the Mediterranean basin is observed, and higher thermicity is expected in the future. The Ombroclimatic Index, and especially the seasonal indices, is the most helpful of these Bioclimatic Indices, showing that the southern Mediterranean areas would be the most vulnerable to climate change.

Sparse spectral unmixing can be modeled as a linear combination of endmembers contained in an overcomplete dictionary weighted by the corresponding sparse abundance vector. This method exploits the fact that there is only a small number of endmembers inside a pixel compared to the overcomplete endmember spectral dictionary. Since the information contained in hyperspectral pixels is often spatially correlated, in this work we propose to jointly estimate the sparse abundance vectors of neighboring hyperspectral pixels within a local window exploiting joint sparsity with common and noncommon endmembers. To demonstrate the efficiency of our framework, we perform experiments using both simulated and real hyperspectral data.

In diesem Projekt wurde ein Programm getestet, welches den Druckaufbau in einem HELIBAR® Extruder modellieren kann. Das bereitgestellte Programm wurde am Institut für Kunststofftechnik in Stuttgart (IKT) entwickelt. Zuerst wird hierzu das Zugrundeliegende mathematische Modell beschrieben. Dieses wird anschließend mit Hilfe der Finiten Differenzen Methode gelöst. Zuletzt erfolgt eine Implementierung des Modells in MATLAB, wobei die theoretisch erhaltenen Ergebnisse mit experimentellen verglichen werden. Das Programm analysiert zweidimensional die Schmelzeförderung im Kanal und kann so den Druck am Ende der Schnecke mit guten Ergebnis vorhersagen. Outgoing

The walls in blood pumps are made of artificial material and thus are thrombogenic to a lesser or larger degree. Also the flow plays a role: a blood flow with no flow separations and stagnation zones is required to avoid the generation of thrombi. A precondition for solving this problem is the assessment of the wall shear rate. However this parameter is difficult to assess because of the deformability of the walls and the pulsation of the flow. Two methods are proposed to estimate the wall shear stress in bloodpumps. The paint erosion method allows a characterisation of the flow near the wall. The second method is a special development of standard Particle Image Velocimetry (PIV). A vector field of the flow close to the wall results. Both methods should permit the assessment of the wall shear stress in bloodpumps.

Objective of the present study is the hemodynamic investigation of the fluidmechanics a ball valve developed for ventricular assist devices with improved parameters. The flow was investigated using Digital Particle Image Velocimetry with an enlarged model of the valve (2.8:1). The flow was recorded using a high speed video camera with 250 fps and analyzed by a cross-correlation method implemented in the software DaVis by LaVision. The results confirmed the improvement of the ball valve performed by a numerical study. The flow separations on the ball valve housing observed in the first design version was eliminated in the final design of the novel valve. Hence a valve of this design applied in ventricular assist devices can be expected to have a lower rate of thromboembolic complications.

Resumen La tutoría alcanza, hoy día, una especial consideración en los procesos de formación de los aspirantes a maestros y profesores. Sin embargo, su práctica habitual promueve un distanciamiento con la didáctica, relegándola a una mera atención al alumnado en relación con cuestiones que no inciden, esencialmente, en el alcance de los propósitos que la universidad debe perseguir. En este trabajo, se pretende ofrecer una significación adecuada de la tutoría en la educación superior, con singular proyección en la formación inicial de los profesores de todo el sistema educativo, promoviendo acciones que la sitúen en el lugar que, como práctica docente, le corresponde. Una revisión crítica de las concepciones y prácticas de la tutoría universitaria, y de sus efectos y consideraciones sobre los alumnos, permite ofrecer los fundamentos y métodos que se precisan para alcanzar el exigente cometido que la didáctica universitaria persigue en la formación inicial de los futuros docentes.
