A Sustainable Energy Mix for the Aeolian Islands
2018
The paper examines the current status of the electrical energy production in the Aeolian Islands, an Italian archipelago, composed by small island North of Sicily. Instead the availability of renewable energy sources, like wind, solar, geothermal and sea wave, these islands produce electrical energy using almost entirely fossil fuels. Starting from this initial condition, the paper proposes an energetic mix based on the available resources and focusing the attention on sea wave. An innovative device is presented in order to exploit this energy source.

Performance Analyses of Innovative Glassblocks for BIPV
2014
The paper illustrates the results of the performance analyses conducted on an innovative glassblock integrated with 3rd generation dye-sensitized solar cells, designed for enabling the construction of translucent and sustainable building envelopes. The analyses encompass the simulation of both thermal and optical performance referring to different configurations of the PV-integrated glassblock, showing the results obtained by using two different software tools: Comsol Multiphysics and WINDOW. The configurations may differ, for example, because of the position of the module inside the glassblock, the type of dye-sensitized solar module used (composition, transparency, design), and glassblock…
homogeneous embeddings of SL2(C) modulo a finite sub-group.
2000
L'objet de ce travail est l'étude des variétés algébriques normales complexes munies d'une action algébrique de $SL_{2}$ et qui contiennent $SL_{2}/H$ comme orbite ouverte, $H$ étant un sous-groupe fini de $SL_{2}$.Plus précisément on définit un plongement homogène de $SL_{2}/H$ comme la donnée d'une $SL_{2}$-variété irréductible $X$ (quasi-projective ou non) contenant $SL_{2}/H$ comme orbite ouverte et d'un morphisme $SL_{2}$-équivariant de $SL_{2}$ dans $X$.Les plongements homogènes lisses ainsi que les plongements minimaux (plongements lisses et complets qui ne sont pas des éclatements d'un autre plongement lisse complet) de $SL_{2}/\{Id\}$ et de $SL_{2}/\{\pm Id\}$ ont été déterminés pa…

Surface and interface effects on the current-voltage characteristic curves of multiwall carbon nanotube-Si hybrid junctions selectively probed throug…
2021
The possibility to increase the efficiency of photovoltaic (PV) cells based on hybrid carbon nanotube (CNT)–Si heterojunctions is related to the ability to control the chemical properties of the CNT–Si interface and of the CNT bundle layer. In spite of the encouraging performances of PV cells based on multiwall (MW) CNT, so far few efforts have been made in the study of this device compared to single wall (SW) CNT–Si interfaces. Here, surface and interface effects on the current–voltage characteristic curves of MW CNT–Si hybrid junctions are investigated through exposure to HF vapors and to 10 ppm-NO2 and compared to the effects detected in SW CNT–Si junctions. Quite similar results in term…
Anomalous performance enhancement effects in Ruthenium-based Dye Sensitized Solar Cells
2017
Dye Sensitized Solar Cells (DSSCs) are nowadays more and more employed since they present lower production costs than traditional silicon photovoltaic devices. An interesting phenomenon affecting such devices consists in the fact that current density-voltage (J-V) characteristic can depend on the history of the cell prior to the measurement, which often can be assimilated to an anomalous hysteresis effect. In this work, we study such phenomenon on Ruthenium-based DSSCs through a series of measurements performed after applying different values of external electrical field to the cell. The measurements have been carried out both under simulated sunlight (AM1.5G - 1000 W/m2) and in the dark. W…
Vārda brīvības ierobežošana, apkarojot aicinājumu uz terorismu
2016
Ievērojot valstu pastiprināto vēlmi cīnīties ar terorismu, vairāki starptautiski dokumenti paredz aicinājuma uz terorisma aizliegšanu. Tas neapšaubāmi ierobežo vārda brīvību, tadēļ svarīgi noskaidrot, kā nošķirt tiesiski pieļaujamu runu no aicinājuma uz terorismu. Autors darbā analizē pastāvošo vārda brīvības tiesisko regulējumu un starptautiskos centienus apkarot aicinājumu uz terorismu, kā arī sniedz pārskatu par to, kādos gadījumos un pie kādiem nosacījumiem, vārda brīvību var ierobežot, lai sasniegtu šādu mērķi. Tiek piedāvāts konkrēts tests, kā nošķirt vārda brīvību no aicinājuma uz terorismu, kā arī tiek vērtēti Eiropas Cilvēktiesību tiesas un ASV Augstākā tiesas piemērotie standarti …
Implicación familiar en el aprendizaje de una asignatura no lingüística en inglés: el caso del CEIP Vil.la Romana
2017
Los resultados académicos están influidos por múltiples variables, entre ellas, la implicación familiar. Diferentes estudios analizan cómo el apoyo familiar favorece el aprendizaje de la lengua y los contenidos de una asignatura, a partir de una valoración positiva, unas expectativas altas, una colaboración con la familia o unas estrategias concretas. La tesis presentada analiza, con población del CEIP Vil·la Romana de Catarroja (Valencia, España), diferentes aspectos de la implicación familiar a la hora de apoyar el aprendizaje de una asignatura no-lingüística, concretamente Ciencias Naturales, que se imparte y se estudia en la lengua extranjera inglés. Para realizar el estudio se ha elabo…
