Energy and Environmental Assessment of a Hybrid Dish-Stirling Concentrating Solar Power Plant
2022
Although the 2019 global pandemic slowed the growing trend of CO2 concentrations in the atmosphere, it has since resumed its rise, prompting world leaders to accelerate the generation of electricity from renewable sources. The study presented in this paper is focused on the evaluation of the energy and environmental benefits corresponding to the hypothesis of hybridizing a dish-Stirling plant installed on the university campus of Palermo (Italy). These analyses were carried out by means of dynamic simulations based on an accurate energy model validated with the experimental data collected during the measurement campaign that occurred during the period of operation of the reference plant. As…
Les représentations spatiales de concepts scientifiques : inventaire et diversité
1994
The consultation of twelve journals (French and English language) that deal with science education, for the years 1991 to 1993, allowed us to summarize the use of spatial representations of scientific concepts in didactics research. Two main results were produced from this study : there has not been much work published with spatial representations, and what has been published is very heterogeneous. Analysis of this diversity does not always allow us to understand the authors’ objectives and obliges researchers in didactics to think about the nature and role of spatial representations in the construction of scientific knowledge.
Decentering, Acceptance, and Non-Attachment : Challenging the Question "Is It Me?"
2021
Among mindfulness measures the three constructs acceptance, decentering, and non-attachment are psychometrically closely related, despite their apparent semantic differences. These three facets present robust psychometric features and can be considered core themes in most “third wave” clinical models. The aim of the present study was to explore the apparently different content domains (acceptance, decentering, and non-attachment) by administering various psychometric scales in a large sample of 608 volunteers. Resilience and depression were also assessed. Exploratory and confirmatory factor analyses performed in two randomly selected subsamples showed a bifactor approximation. The explained…
Validation of a modified version of the Experiences of Teaching and Learning Questionnaire
2018
Providing teaching-learning environments that foster university studentsö learning is an essential task of higher education. Valid and reliable tools for assessing them are therefore needed. This study investigates the measurement properties of a modified version of the Experiences of Teaching and Learning Questionnaire (ETLQ). Two independent data-sets (N = 1637 and N = 1711) were collected from Finnish university students. Confirmatory factor analyses resulted in a modified measurement model for the ETLQ, consisting of 11 factors. The first three factors assessing the teaching-learning environment – Teaching for Understanding, Disciplinary Understanding and Supportive Teaching – were indi…

No. of bitstreams: 0 Previous issue date: 2004-03-01 Double lip is a developmental abnormality which may occur either isolated or as a component of Ascher's syndrome. A case of congenital double lip associated to hemangiomas and enlargement of the thyroid is reported. The oral and facial hemangiomas were excised under local anesthesia. Surgical reconstruction of the upper li…
Els epítets dels artistes baixmedievals al servei dels poders reial i municipal
2021
Aquest article estudia els adjectius que van rebre els artistes que treballaren per al rei i per a les elits ciutadanes en els territoris de parla catalana durant els segles XIV i XV. En particular, se n’hi examinen dos: apte i subtil. Les notícies exhumades per uns altres especialistes fins al moment permeten comprendre’ls en el propi context documental. Ací es compara el seu significat amb uns altres exemples de la literatura baixmedieval de la Corona d’Aragó i es du a terme una aproximació històrica com a paraules que al·ludien a la perícia de l’artista i que van ser escollides amb una finalitat. Participaren i repercutiren, per tant, en la relació històrica de l’artista amb el client, …
Validación de una Medida de Clima de Servicio en las Organizaciones
2012
Service climate is critical for organizations pertaining to the service sector. It reflects the importance organizations attribute to service quality and efforts to please customers. Using previous work of Schneider, White, and Paul (1998) as starting point, this research validates a measure of service climate in the Spanish language. Data from two survey study projects were brought together. A total of 120 hotels, located in Spain, participated in the research. The sample consisted of 508 frontline hotel employees distributed in 152 work-units. Our results confirmed that construct and predictive validity are satisfactory, with four factors describing the facets of service climate: Global S…
Constructed wetlands as nature-based solution for sustainable wastewater management in urban areas: a critical assessment by experimental studies and…
2022
In urban areas, constructed wetland systems (CWS) have been recognized as one of the most valid technologies for sustainable wastewater management. They represent green infrastructure and provide solutions to treatment of wastewaters that cities and peri-urban areas produce in large amount. In particular, CWS offer the advantages of wastewater reuse for parklands irrigation, water storage and peak-flow attenuation, control of stormwater runoff, nutrient cycling and uptake, heavy metals sequestration, removal of organic compounds. In greener cities, these systems have the potential to perform not just hydrological and wastewater treatment functions, but also urban design and ecological aspec…

Construction Guilds in Southern Italy and the Islands (15th-16th Centuries): Leadership and Rivalries
2020
In the South of Italy and the big islands, in counter-trend with respect to the rest of the peninsula, construction guilds know a renewed vitality between the last decades of 15th and the beginning of 16th centuries. Rules, prerogatives and operative modes are regulated by statutes, often undersigned by the masters included in the trade organization, mentioning also the other actors involved in the approval processes. The intertwining of these and other archival documents sometimes reveals the leading role played within the guild by masters that overcome the anonymity usually considered to be inherent in the corporate system. Comparing the rules and the boundaries among specific trades esta…
