Cancer mortality inequalities in urban areas: a Bayesian small area analysis in Spanish cities

Intra-urban inequalities in mortality have been infrequently analysed in European contexts. The aim of the present study was to analyse patterns of cancer mortality and their relationship with socioeconomic deprivation in small areas in 11 Spanish cities

A mixed H2/H∞-based semiactive control for vibration mitigation in flexible structures

In this paper, we address this problem through the design of a semiactive controller based on the mixed H2/H∞ control theory. The vibrations caused by the seismic motions are mitigated by a semiactive damper installed in the bottom of the structure. It is meant by semiactive damper, a device that absorbs but cannot inject energy into the system. Sufficient conditions for the design of a desired control are given in terms of linear matrix inequalities (LMIs). A controller that guarantees asymptotic stability and a mixed H2/H∞ performance is then developed. An algorithm is proposed to handle the semiactive nature of the actuator. The performance of the controller is experimentally evaluated in a real-time hybrid testing facility that consists of a physical specimen (a small-scale magnetorheological damper) and a numerical model (a large-scale three-story building)

New delay-dependent stability criteria for uncertain neutral systems with mixed time-varying delays and nonlinear perturbations

The problem of stability analysis for a class of neutral systems with mixed time-varying neutral, discrete and distributed delays and nonlinear parameter perturbations is addressed. By introducing a novel Lyapunov-Krasovskii functional and combining the descriptor model transformation, the Leibniz-Newton formula, some free-weighting matrices, and a suitable change of variables, new sufficient conditions are established for the stability of the considered system, which are neutral-delay-dependent, discrete-delay-range dependent, and distributeddelay-dependent. The conditions are presented in terms of linear matrix inequalities (LMIs) and can be efficiently solved using convex programming techniques. Two numerical examples are given to illustrate the efficiency of the proposed method

El cinema i la constitució d'un públic popular a Barcelona. El cas del Paral·lel

Between 1895 and 1910 Barcelona saw a whole range of social, political and cultural changes due to the increasingly important emergence of the working masses. At the same time, the cinema arrived in Catalonia, becoming very quickly one of the favorite entertainments of the urban laboring population which was about creating a new culture opposed to the modernist and nineteenth-century elite .This is, broadly speaking, the context that serves as a starting point for a study of the role of cinema in shaping a mass audience in Barcelona, an analysis centered on new urban spaces intended for the leisure of the lower classes emerged with the birth of modern Barcelona, especially the “Paral•lel” avenue, whose opening in 1894 made even more apparent the great social tensions and existing inequalities in Barcelona’s society at the end of the century.

La infermeria d'atenció primària en l'atenció als problemes del peu en la diabetis tipus 2 a Catalunya

Aquesta tesi pretén respondre a la pregunta: Què pot fer la infermeria d'atenció primària i què és el què fa, en els problemes del peu en persones amb diabetis tipus 2 a Catalunya?. L'estat del tema exposa la importància de les complicacions en el peu i la possibilitat de reduir-les amb un paper rellevant de la infermeria d'atenció primària. La investigació s'ha centrat en conèixer de què disposa, les activitats que desenvolupa, i què li manca a la infermeria per desenvolupar el seu potencial. Els resultats observats són representatius i mostren clares desigualtats assistencials entre centres, regions sanitàries i tipus de gestió. Suggerint que en l'atenció primària convé organitzar i coordinar l'atenció als problemes del peu en la diabetis, millorar la formació i la capacitació infermera en el tema, fomentar i optimitzar la presència de professionals especialitzats, i potenciar l'educació en diabetis i la promoció de la salut.
