All-Organic Waveguide Sensor for Volatile Solvent Sensing
2019
This work was supported by ERDF 1.1.1.1 Activity Project Nr. 1.1.1.1/16/A/046 “Application assessment of novel organic materials by prototyping of photonic devices”. We acknowledge Igors MIHAILOVS for valuable discussions.
Nickel-Indium Sulphide Core-Shell Nanostructures Obtained by Spray-ILGAR Deposition
2013
Ni nanowires (NWs) of different lengths were fabricated by pulsed potentiostatic deposition within pores of polycarbonate membranes. After template dissolution, substrates underwent sequential Spray-ILGAR (R) depositions of thin indium sulphide films. The effect of deposition temperature was also investigated. For low number of deposition cycles, results showed complete and uniform covering of metal over the entire length of NWs, with formation of Ni - In2S3 core-shell structures. However, with increasing number of deposition cycles films became uneven and crusty, especially at higher temperatures, owing to the simultaneous formation of nickel sulfide. This drawback was almost eliminated do…
Electrodeposition and characterization of Mo oxide nanostructures
2015
Template electrodeposition has been used to grow uniform arrays of molybdenum oxide nanostructures in polycarbonate membrane. Several parameters have been investigated, like electrodeposition, time and solution pH. These parameters do not influence the nature of the deposit that always consists of mixed valence molybdenum oxides, whereas the nanostructure morphology changes with pH. In particular, at low pH (2.7), nanotubes are formed, whilst arrays of nanowires are obtained above pH 5.5. This change of morphology is likely due to H2 bubbles evolution during the electrochemical deposition, particularly occurring at low pH. It was found that fast removal of H2 bubbles through vigorous stirri…
Di corsa, per forza. Performances rituali per la Domenica di Pasqua in Sicilia
2020
Several sicilian religious celebrations are characterized by a particular mode of processional transport of the fercoli with the statues of the Saints. These are made to run and dance by devoted young men, often competing with each other, both on the streets of the inhabited centers and, in rare cases, inside the religious buildings. This mode of transport is called, especially in the countries of the western Agrigento’s area, “rigattiata”. Many evidences, first of all the agonal climate, suggest that the same performative logic presides over the ritual execution of the “rigattiati” and the ergological action of the work in the fields. The competitive and conflicting climate between two or …
Analysis of Sustainable Performance in Romania’s Local Public Administrations: An External Stakeholders Perspective
2016
Building a sustainable performance system at the level of the local public administrations must have as starting point the local public administration’s (LPA) mission and must go down to the level of the individual. This system must follow the external performance that it delivers to the citizens, the outcomes generated, but also the internal performance which suggests how to achieve the external performance. We propose in this regard the simultaneous use of the Balanced Scorecard tool for managing the internal performance and the Public Service Value Model for measuring the external performance measurement which derives from the organization's mission. In the second part of the work we ana…

RUNX3 and T-Bet in Immunopathogenesis of Ankylosing Spondylitis—Novel Targets for Therapy?
2019
Susceptibility to ankylosing spondylitis (AS) is polygenic with more than 100 genes identified to date. These include HLA-B27 and the aminopeptidases (ERAP1, ERAP2, and LNPEPS), which are involved in antigen processing and presentation to T-cells, and several genes (IL23R, IL6R, STAT3, JAK2, IL1R1/2, IL12B, and IL7R) involved in IL23 driven pathways of inflammation. AS is also strongly associated with polymorphisms in two transcription factors, RUNX3 and T-bet (encoded by TBX21), which are important in T-cell development and function. The influence of these genes on the pathogenesis of AS and their potential for identifying drug targets is discussed here.
Are scholarships effective in Spain? An impact assessment of the upper secondary non-tertiary level
2014
España tiene un gran reto a futuro en la gran cantidad de individuos que no finalizan sus estudios más allá de la escolarización obligatoria y que se traduce en una alta tasa de abandono escolar prematuro y una baja tasa de graduación en secundaria post-obligatoria. En este marco, el objetivo de este trabajo es identificar si la política de becas, llevada a cabo durante el período 2004-2005 en España, ha sido eficaz en su objetivo de incrementar el porcentaje de alumnos que finalizan con éxito el nivel secundario post-obligatorio. Para ello se aplicará una evaluación de impacto (ex-post) con información individual para conocer si hubo cambios en las tasas de finalización del nivel educativo…
Els «criteris de visibilització de les dones» en català: límits sintacticosemàntics i discursius
2013
L'objectiu d'aquest article és analitzar els principals criteris que les guies d'estil recomanen per visibilitzar les dones ¿o per fer un ús no sexista del llenguatge¿ des de dos punts de vista: el sintacticosemàntic i el discursiu. Des del punt de vista sintacticosemàntic, s'estudien bàsicament els fenòmens relacionats amb la coordinació, la concordança i la repetició o elisió d'elements (per exemple, especificadors del nom), i la manera com les diferents opcions afecten el significat oracional. Des del punt de vista discursiu, s'analitzen els fenòmens relacionats amb la coreferència; és a dir, la relació entre les diferents maneres d'expressar un mateix referent per mitjà d'elements nomin…
Con li suoi vestimenti asciugare il morto viso della salata acqua, e bagnarlo di molte lagrime: la "Fiammetta" en el "Leànder y Hero" de Roís de Core…
2005
The «Elegia di madonna Fiammetta» has an evident impact of the story of Leandre and Hero, especially in the moments in which the lady suffers while waiting for her lover, who never comes. Fiammetta makes obvious this parallelism on several occasions, and manages to invent an end for the story loaded of pathos. Joan Roís de Corella realises about this relationship between both two works and makes the inverse path: he uses the tone and some narrative elements of the Elegia for writing his Leander and Hero. It is demonstrated that the so contreversial end of Corella’s story is not original of the Valencian, but it also depends on Boccaccio’s text
