Cognitive-behavioral treatment of online role-playing videogames: proposal of treatment and a case study
2014
El propósito de este trabajo es presentar una propuesta de tratamiento cognitivo-conductual para la intervención en la adicción a video juegos. Se presenta el caso de un varón de 21 años con problemas con el uso de los videojuegos. Se expone el procedimiento en cada una de las fases de las que consta el tratamiento, así como los resultados de su eficacia en un estudio de caso. Después de trece semanas de intervención se aprecian importantes cambios en el nivel de dependencia. Los resultados muestran una disminución significativa del tiempo de uso del ordenador y de juego, así como una mejoría del funcionamiento personal y social del paciente. This article provides a proposal of cognitive-be…

Polisemia di nòmos e l'esordio di Hipp. de genitura
2016
Far from being, as has been said, “the bizarrest beginning of all the Hippocratic writings (...) deserving of therapy”, this paper aims to show that the opening words of the Hippocratic writing “On Generation” (νόμοϲ μὲν πάντα κρατύνει), in itself echoing a famous Pindaric motto, seem to be used first of all in order to evoke a cultural, intellectual and scientific world, in which the nòmos has become one of the most important keywords of the time. From this point of view, the Pindaric quotation seems to be played out on the wide semantic range of nòmos as well as on the ambiguous meaning of the verb κρατύνω, which in this embryological context denote specifically the consolidation and hard…
Pressure-Dependent Tuning of Photoluminescence and Size Distribution of Carbon Nanodots for Theranostic Anticancer Applications
2020
Carbon nanodots (CDs) have recently attracted attention in the field of nanomedicine because of the biocompatibility, cost-effective nature, high specific surface, good near infrared (NIR) photothermal conversion into heat and tunable fluorescence properties, which have paved the way toward incorporating use of CDs into innovative anticancer theranostic platforms. However, a reliable synthesis of CDs with established and controlled physiochemical proprieties is precluded owing to the lack of full manipulation of thermodynamic parameters during the synthesis, thus limiting their use in real world medical applications. Herein, we developed a robust solvothermal protocol which allow fine contr…
Intravenous iron therapy in patients with heart failure. A double-edged sword
2013
We read with interest the article of Beck-da-Silva et al., who recently concluded that intravenous (IV) iron seems to be superior over oral supplementation for improving functional capacity of heart failure patients [1]. Irrespective of the study design, involving comparison of functional outcomes between two different means of iron supplementation, we raise some clinical issues about the rationale underlying this investigation. According to the data published by Beck-da-Silva et al., the modest number of patients (n = 23) enrolled in this multicenter investigation had moderate anemia (i.e., hemoglobin concentration comprised between 90 and 120 g/L) but no evidence of iron deficiency, which…
Laser fluence, repetition rate and pulse duration effects on paint ablation
2006
Abstract The efficiency (mm3/(J pulse)) of laser ablation of paint was investigated with nanosecond pulsed Nd:YAG lasers (λ = 532 nm) as a function of the following laser beam parameters: pulse repetition rate (1–10,000 Hz), laser fluence (0.1–5 J/cm2) and pulse duration (5 ns and 100 ns). In our study, the best ablation efficiency (η ≅ 0.3 mm3/J) was obtained with the highest repetition rate (10 kHz) at the fluence F = 1.5 J/cm2. This ablation efficiency can be associated with heat accumulation at high repetition rate, which leads to the ablation threshold decrease. Despite the low thermal diffusivity and the low optical absorption of the paint (thermal confinement regime), the ablation th…
Environmental Effects on Mechanical, Thermophysical and Electrical Properties of Epoxy Resin Filled with Carbon Nanofillers
2019
The aim of this work was to establish the effect of environmental factors (moisture and temperature) on some mechanical, electrical and thermal properties of epoxy-based composites filled with carbon nanofillers: nanotubes (CNT), nanofibers (CNF) and hybrid nanofiller (nanotubes/nanofibers in the ratio 1:1) and to reveal the most environmentally stable NC. First, the nanocomposites (NC) containing different nanofiller contents were prepared to evaluate electrical percolation threshold and to choose NC at certain electrical conductivity for further characterization of the physical properties in initial state and during/after environmental ageing. The environmental ageing consisted of water a…
Simulation studies of electronic transport in a-Si:H thin film solar cells
2009
The thin film solar cells in Hydrogenated Amorphous Silicon (a-Si:H) are attractive for cheaper production and used in ultra low cost, high volume applications but have a relatively lower electronic performance. These limitations are mainly due to properties of the a-Si:H and relies on the production technique. In this study we investigate the physical mechanisms which are on the basis of the electronic transport and their relation with the technological processes. The transport-simulation computer program ATLAS (Silvaco) has been used to examine the role of the mid gap defect density in determining the performance of a-Si:H p-i-n homojunction solar cell.
