Integrazione di celle fotovoltaiche ibride nel vetromattone

2012

L’invenzione riguarda l’integrazione del vetromattone con celle solari ibride (organiche/inorganiche), conosciute come Dye-sensitized Solar Cell (DSC). La combinazione del vetromattone con le DSC consente di migliorare le prestazioni del prodotto originario rendendolo in grado di produrre energia pulita. Le caratteristiche di trasparenza e isolamento termo-acustico del prodotto possono essere regolate agendo sulla configurazione delle DSC. Il prodotto può essere assemblato a formare pannelli fotovoltaici per la realizzazione di facciate traslucide energeticamente “attive” in varie condizioni luminose (condizioni di luce diffusa o artificiale) e indipendentemente dall’angolo di radiazione so…

The integration of Dye-sensitized Solar Cell (DSC) with the glassblock is disclosed. The combination of the two technological elements the glassblock and the DSC module enhance their own peculiarities. The final complete product is ready-made for installation owns the qualities of the glassblock and produces sustainable energy at the same time. The transparency and the thermo-acoustic insulation may be modulated according to the specific requirements of each case of installation. The product may be used for example to create PV panels for glazed and translucent façades that are able to perform efficiently in all light conditions (even in diffuse light also converting internal artificial light) that are not dependant on the angle of the solar radiation and do not suffer from the high operative temperatures of functioning due to the peculiarities of the DSCs. DSCs are made of economic and biocompatible materials and are produced with low-cost and highly productive printing methods on rigid or flexible substrates. With the integration of DSC modules with the glassblock PV panels coincide with the envelope itself so that they do not need any further structures to be installed on and allow the possibility of subtract from the price of the panel the price of the substituted building element allowing further economies. DSCs can be printed in different colours and with various patterns offering to designers and customers the possibility of intervening on the glassblock aesthetical aspect also taking advantage of the peculiar modularity of the glassblock for larger compositions of drawings on the building’s façade. Seven Hypotheses of integration are discussed in order to obtain DSC-integrated glassblock ready for the construction of a precast and dry-assembled PV panel which can use the horizontal and vertical cavities between the glassblocks to house plastic profiles where the electric interconnections and the steel bars -useful for improve the mechanical resistance of the panel- are integrated.Settore ICAR/10 - Architettura Tecnica

Pannello precompresso di vetromattoni assemblati a secco per la realizzazione di involucri traslucidi

2012

L’invenzione riguarda la realizzazione di un pannello di vetromattoni montati “a secco” -da impiegare per la realizzazione di involucri edilizi traslucidi anche nel caso di edifici alti- che è in grado di rispondere adeguatamente alle sollecitazioni orizzontali (quali quelle dovute a vento e sisma) grazie all’applicazione della tecnica della precompressione mondirezionale. Per offrire una risposta ai limiti imposti dalla tecnica di assemblaggio tradizionale dei vetromattoni (“ad umido”), l’applicazione della precompressione consente, infatti, di dare ai pannelli preassemblati “a secco” una rigidezza adeguata anche in direzione normale al loro piano di posa, sfruttando le buone caratteristic…

The invention is related to the construction of a glassblock panel “dry assembled” that can be used to build translucent building envelope even in high-rise buildings. This panel is able to contrast the horizontal actions due to wind and earthquake by means of the application of unidirectional pre-stressing technique. To overcame the limits due to the “wet assembly” system traditionally used to assemble the glassblocks the use of prestressing technique allow the panels to have an adequate mechanical resistance against the actions perpendicular to their installation plane. In this configuration the mechanical resistance of the glassblocks is exploited. The unidirectional prestressing (along the prevalent dimension of the panel) is obtained through the grip of the nuts inserted in the steel bars that are housed inside the glassblocks supporting profiles positioned in the vertical cavities between the glassblocks and passing through the horizontal profiles useful to separate glassblock rows from each other. The proper nuts grip opposing to the steel plates positioned at the top and bottom of the panel allow to prestress the panel. The steel plate are positioned on a plastic plate fixed to the lateral faces of the glassblocks by means of resins.Settore ICAR/10 - Architettura Tecnica

Sport and Quality of Life

2022

Negli ultimi trent’anni lo sport ha assunto un significato molto rilevante nella vita delle persone e, seppure con notevoli differenze, sia nei paesi a sviluppo economico avanzato, sia in quelli in via di sviluppo. A livello individuale, esso ha costituito un’area di investimento identitario quando ha assunto la forma di sport spettacolo del quale fruire, alimentando la pratica del tifo e il fandom o costituendo il modello di uno stile di vita vincente; ma anche quando ha assunto la forma di pratica del tempo libero attraverso la quale tenersi in forma, facendo crescere, in questo caso, la diffusione di una cultura della salute e del benessere. Si tratta di due modalità di approcciare al co…

but also when he took the form of free time practice through which to keep fit making grow in this case the diffusion of a culture of health and well-being. These are two ways of approaching the consumption of sports by spectators and actorIn the last thirty years sport has taken on a very significant meaning in people's lives and albeit with considerable differences both in advanced economic development countries and in developing countries. On an individual level it constituted an area of identity investment when it assumed the shape of “sport spectacle” to be enjoyed fueling the practice of cheering and fandom or constituting the model of a winning lifestyleand the two ways of use can be strongly related to the perception and assessment of the quality of life. The “semantic universes” which however connote sport and “free time sports” have often appeared polarized. Commercial sport and sports professionalism are intertwined with the institutions of economics politics and culture which above all stress its “spectacularity” in order to capture first and foremost the audience. But also the sport of leisure time is intertwined with the actions of the institutions of economics politics and culture with the difference that these stress above all its “healthy value” aimed at the “healthy and rational” investment of time in an activity which improves the quality of life in the short medium and long period. This polarization between the consumption of sport entertainment - commercial sport - and the consumption of sport as a leisure activity - sport for all - has become increasingly interconnected precisely because of the increased collective identity demand via sport. In other words we have witnessed the spread of shape of sports entertainment that recall the importance of sports for psychophysical well-being for integration and social participation for the reduction of social inequalities ethnic and cultural differences and in which the importance assumed was weakened in the show from agonism from competition from the physical confrontation between two contenders or two teams. A sport in which we act with competitors as well as against competitors. And on the other hand we have gradually witnessed the spectacularization of sports in our free time to the point that the sharing of the results obtained through the declination of a competitive spirit that presents itself as directed no longer against other contenders but against its own performance limits it has become the way in which each person makes part of his or her own life spectacular the one he often considers most authentic. The aim of this work is to describe how the intertwining between the commercial/professional dimension of the sports show and the playful/recreational dimension of sports practice are fueled by a demand and an offer of social identity that characterizes these two “semantic universes”.Settore SPS/07 - Sociologia Generale

Optimization and quantification of stimulation parameters in subthalamic nucleus deep brain stimulation for Parkinson's disease

2014

La estimulación cerebral profunda del núcleo subtalámico (ECP-NST) es un tratamiento seguro y eficaz en pacientes seleccionados con enfermedad de Parkinson (EP) avanzada. El éxito de la misma depende de la precisión en la implantación de los electrodos y una correcta programación de los parámetros de estimulación. Actualmente existen ciertas guías para la selección de los parámetros de estimulación. Éstas han asumido de forma empírica que el efecto agudo de la estimulación determinaría una buena evolución a largo plazo. El sitio óptimo de estimulación dentro del área subtalámica ha sido y continua siendo una cuestión ampliamente debatida. Conocer el sitio óptimo de estimulación tiene implic…

Marx y Engels y la división sexual del trabajo en la familia: ambigüedades, equívocos y vacíos teóricos

2018

Dada la importante influencia de Marx y Engels en el análisis de la estructura social, no sorprende el notable impacto de su obra en el estudio del papel de la mujer en la familia. Sin embargo, su herencia en este ámbito sociológico ha dado lugar a interpretaciones muy polarizadas. Este artículo quiere aportar algo de luz evidenciando las contradicciones del marxismo al estudiar el papel de la mujer en la familia. Para ello se comparan las contribuciones de Marx y Engels para calibrar posibles diferencias en las posturas de dos autores que en otros ámbitos han presentado un pensamiento muy homogéneo. Los resultados obtenidos permiten afirmar que, a pesar de su innegable influencia en el pen…
