Design of a Cleaning Program for a PV Plant Based on Analysis of Energy Losses
2015
Solar photovoltaic (PV) energy has grown significantly over the past few years. However, despite the increase in installed capacity, this energy source still raises important concerns related to the variability of power production. The short-term effects such as cloud shadowing and supply interruptions, as well as long-term effects such as dust accumulation, seasonal variation, and ageing of PV modules, can cause variability of power production. Therefore, the analysis of all the variability sources in order to provide statistically consistent power production data is an important challenge. This study presents a methodology to analyze data from a PV plant in order to have an independent ev…
Crystal Structures and Density Functional Theory Calculations of o-and p-Nitroaniline Derivatives: Combined Effect of Hydrogen Bonding and aromatic i…
2013
The interplay of strong and weak hydrogen bonds, dipole–dipole interactions, and aromatic interactions of o- and p-nitroaniline derivatives was studied by combining crystal structure analysis and density functional theory (DFT) calculations. Crystal structures of four 2-nitroaniline derivatives, 2-((2-nitrophenyl)amino)ethyl methanesulfonate (1A), 2-((2-nitrophenyl)amino)ethyl 4-methylbenzenesulfonate (2A), N,N′-((1,3-phenylenebis(oxy))bis(ethane-2,1-diyl))bis(2-nitroaniline) (3A), and N-(2-chloroethyl)-2-nitroaniline (4A), and crystal structures of three 4-nitroaniline derivatives, 2-((4-nitrophenyl)amino)ethyl methanesulfonate (1B), 2-((4-nitrophenyl)amino)ethyl 4-methylbenzenesulfonate (…
Evidence of Weak Halogen Bonding: New Insights on Itraconazole and its Succinic Acid Cocrystal
2012
Exact knowledge of the crystal structure of drugs and lead compounds plays a significant role in the fields of crystal engineering, docking, computational modeling (drug–receptor interactions), and rational design of potent drugs in pharmaceutical chemistry. The succinic acid cocrystal of the systemic antifungal drug, itraconazole, reported by Remenar et al. (J. Am. Chem. Soc.2003, 125, 8456–8457) (CSD: IKEQEU), represents one of the classical examples displaying a molecular fitting mechanism in the solid state. In this work, we disclose the X-ray single-crystal structure of the cis-itraconazole–succinic acid (2:1) cocrystal and found that it differs slightly from the previously reported st…

Behavior change types with Pokémon GO
2017
Digital games1 are one of the most popular entertainment media in the world. Teir allure and widespread popularity makes them an interesting and highly potential platform for behavior change atempts. In this paper, we investigate what types of behavior changes Pokémon GO has promoted or induced among its players. Te study is based on an online survey sample of 262 Pokémon GO players, collected using the critical incident technique and analyzed using qualitative methods. Te analysis shows that the behavior changes induced by Pokémon GO are not just restricted to increased physical activity or social behavior but are actually much more multifaceted: players were more social, found their routi…
Riconfigurare i territori metroplitani. Forme di urbanizzazione e fenomeni di pressione insediativa sui sistemi di interesse naturale in Sicilia
2018
The consumption of the soil due to urbanization it is a phenomena already for many years under observations, but of which only the scientific environment has noticed the elevated environmental impact progress. From a disciplinary point of view, is possible to identify a line of research focusing on the analysis and identification of new morphologies of urbanization and on the interaction among different settlement patterns coexisting in a specific context. This reading complements with the scientific production about the forms of settlement pressure on environmental systems, producing change and deterioration on natural ecosystems and loss of biodiversity. A necessary reference for this lin…
The Conference Reimagined. Postcards, Letters, and Camping Together in Undressed Places
2019
In this paper, five authors account for the rethinking of a conference as a series of postcards, letters, rules and silent moments so that traditional hierarchies of knowledge could be overturned or, at least, sidelined. We recount how the place we convened was enlisted as an actor and the dramas and devices we applied to encounter it. We use this accounting to problematize the conventional practices of goal-oriented meetings and co-authored papers as forms of academic meaning-making. In finding a meeting point where expertise was disorientated and status undressed, we were able to investigate the idea of co-being between human and nonhuman realities as the step social theory needs to take …
Let's talk business! : a task-based material package of public speaking and small talk in the BELF context
2012
Arvioiden mukaan lähivuosina yli kolmannes maailman ihmisistä käyttää englannin kieltä. Tämä on jo vuosia näkynyt ja tulee myös tulevaisuudessa yhä enemmän näkymään kansainvälisessä liike-elämässä, jossa englantia käytetään lingua francana. Eritoten englannin suullinen taito, kuten julkinen puhuminen ja small talk, näyttelevät suurta roolia tässä kontekstissa. Huomionarvoista on kuitenkin se, että hyvin usein liike-elämän kieli- ja viestintäkoulutuksen opetusmateriaalit epäonnistuvat valmistamaan kansainvälisen liike-elämän toimijoita tosielämän tilanteisiin. Tästä johtuen olen maisterintutkielmassani koonnut opetusmateriaalipaketin, jonka keskiössä on ensinnäkin tulevien liike-elämän toimi…
An Edutainment Implementation in an English Vocational Training Class
2021
Edutainment ha sido definido como la unión entre la educación y el entretenimiento, aspectos que todo profesor querría tener en sus clases. Sin embargo, todavía no hay una implementación suficiente del enfoque para afirmar de una forma clara si es útil utilizarlo en las clases de aprendizaje de segundas lenguas o lenguas extranjeras. Este estudio tiene la ambición de contribuir a la comunidad educativa con un caso que podría ser un punto de partida para futuras investigaciones. En este trabajo se describe una investigación que duró 2 semanas en dos grupos de alumnos de 1º de un curso superior de formación profesional, donde se implementó el Edutainment en el grupo experimental y se implemen…
Task-focused behaviour and mothers' causal attributions in relation to dyslexia : a follow-up from age 8 to age 20
2018
Children with dyslexia tend to find reading stressful. Coping responses, such as task-focused and avoidant behaviours, can help mitigate the stress. Task-focused behaviour is associated with reading development, with others’ at-tributions of success and failure linked to task-focused behaviour. The present study aims to examine whether differences in task-focused behaviour between those with dyslexia and those without dyslexia exist in childhood (age 8) and persist in adolescence (age 15) and early adulthood (age 20). The study also aimed to understand the relationship between mothers’ causal attributions of their 15-year-old adolescents’ school successes and fail-ures and task-focused beha…
