Torre tecnologica e percorsi dell’acqua: un possibile sistema di fruizione

2020

L'articolo presenta i risultati di un esercizio laboratoriale condotto con gli studenti del Corso di Laurea magistrale LM4 in Ingegneria edile - Architettura. L’idea parte dalla reinterpretazione delle torri piezometriche, utilizzate per mettere in pressione l’acqua proveniente dai canali sotterranei che irrorano la Conca d'Oro di Palermo e la Fossa della Garofala. L’originaria torre tronco piramidale a base quadrata è stata opportunamente modificata nella forma e nella funzione, svuotata all’interno in modo da consentirvi l'accesso. Chi entra potrà sostare, godere dell’ombreggiamento e della frescura prodotta da un sistema di raffrescamento evaporativo collocato nella parte sommitale della…

Multicellular tumor spheroids: an underestimated tool is catching up again.

2009

The present article highlights the rationale, potential and flexibility of tumor spheroid mono- and cocultures for implementation into state of the art anti-cancer therapy test platforms. Unlike classical monolayer-based models, spheroids strikingly mirror the 3D cellular context and therapeutically relevant pathophysiological gradients of in vivo tumors. Some concepts for standardization and automation of spheroid culturing, monitoring and analysis are discussed, and the challenges to define the most convenient analytical endpoints for therapy testing are outlined. The potential of spheroids to contribute to either the elimination of poor drug candidates at the pre-animal and pre-clinical …

Revista electrónica de investigación y evaluación educativa

2010

Este trabajo tiene el propósito de mostrar el uso de la metodología de Modelos de Ecuaciones Estructurales (SEM) para validar la estructura conceptual de cuestionarios de contexto que se utilizan en los estudios nacionales e internacionales para evaluar el logro educativo de los escolares. Desgraciadamente, los organismos evaluadores no destinan los mismos recursos técnicos a los cuestionarios de contexto que a las pruebas de aprendizaje, por lo que rara vez los primeros son sujetos a estudios de validez. Para mostrar el uso de la metodología SEM, se seleccionó el cuestionario dirigido a alumnos que utilizó el Instituto Nacional para la Evaluación de la Educación (INEE) para conocer los fac…

Assessment of Modelling Structure and Data Availability Influence on Urban Flood Damage Modelling Uncertainty

2014

Abstract In modelling application, different model structures may be equally reliable in terms of calibration ability but they may produce different uncertainty levels; moreover, available data during model calibration may influence the uncertainty linked to the predictions of the same modelling structure. In the present paper, Bayesian model-averaging was applied to several flood damage estimation models in order to identify the best model combination for urban flooding distribution analysis in Palermo city center (Italy). During the analysis, was taken into account the effect of the available data growth on the model uncertainty with respect to the different combination of models outputs.

Validación de una escala reducida para valorar competencias básicas de aprendizaje del alumnado universitario

2021

[ES] La relación entre evaluación y desarrollo de las competencias básicas para el aprendizaje del alumnado universitario es indiscutible, pues la evaluación juega un papel relevante al determinar lo que aprende el alumnado y la forma en la que realiza sus tareas académicas. Con el objetivo de contribuir en el avance de la metodología evaluativa para la valoración de dichas competencias, este estudio pretende validar una escala reducida la cual ha sido adaptada del Autoinforme de desarrollo de las competencias básicas de los estudiantes –COMPES-. Dicha escala busca medir, de forma concisa y breve, el nivel competencial percibido por parte del alumnado respecto a un conjunto de competencias …

STeVAL : rapport om utvikling og utprøving av et konsept for studentevaluering av undervisning og læring i høyere utdanning

2003

Rutiner for systematisk studentevaluering av undervisningen i høyere utdanning er noe som i følge den nye kvalitetsreformen vil få større plass på universiteter og høgskoler fra og med studieåret 2003. Mange av disse institusjonene har erfaringer med å la studentene foreta en slik evaluering av undervisningen midtveis eller på slutten av et semester eller studieår. Men et system for studentenes daglige tilbakemeldinger på undervisningen, og sitt eget læringsutbytte av denne, er det grunn til å tro er både lite anvendt og systematisert. Denne rapporten, og pilotprosjektet den bygger på, er ett bidrag til å utvikle en slik gjennomløpende form for studentevaluering i høyere utdanning. Prosjekt…

La Valle dei Templi in epoca medioevale. Caratterizzazione antropologica e paleopatologica delle sepolture antistanti in Tempio della Concordia

2021

Riassunto ― Il lavoro presenta i risultati delle analisi bio-archeologiche effettuate su resti scheletrici umani rinvenuti in quattordici sepolture di epoca medioevale rinvenute nel Parco Archeologico della Valle dei Templi di Agrigento (Sicilia). L’obiettivo è stato l’acquisizione delle informazioni necessarie per la ricostruzione del profilo biologico di ciascun individuo, al fine di determinarne il sesso, la stima dell’età biologica alla morte, la stima della statura e la valutazione delle patologie e degli indicatori di stress occupazionale mediante le correnti metodologie e tecniche diagnostiche di tipo antropologico. Sebbene il cattivo stato di conservazione di alcuni individui non ne…

Summary ― The work presents the results of the bio-archaeological analyzes carried out on human skeletal remains found in fourteen burials of Medieval chronology at the Archaeological Park of Valle dei Templi in Agrigentum (Sicily). The aim of the work was the acquisition of the information necessary for the reconstruction of the biological profile of each individual throught the determination of sex the estimate of the biological age at death the estimate of height and the evaluation of pathologies and markers of occupational stress through current anthropological diagnostic methodologies and techniques. Althought the poor state of conservation of some individuals has not allowed their whole anthropological characterization the investigations have highlighted the heterogeneity relating to the age groups and have allowed us to ascertain the presence of pathological alterations in subjects of mature age sometimes of unknown etiology such as DISH (Diffuse Idiopathic Hyperostosis). The sample size is not representative of the entire population but subsequent insights will provide a better understanding of the population dynamics of Medieval Agrigentum.Settore BIO/08 - Antropologia

Impact of Land Cover Change Induced by a Fire Event on the Surface Energy Fluxes Derived from Remote Sensing

2015

Forest fires affect the natural cycle of the vegetation, and the structure and functioning of ecosystems. As a consequence of defoliation and vegetation mortality, surface energy flux patterns can suffer variations. Remote sensing techniques together with surface energy balance modeling offer the opportunity to explore these changes. In this paper we focus on a Mediterranean forest ecosystem. A fire event occurred in 2001 in Almodovar del Pinar (Spain) affecting a pine and shrub area. A two-source energy balance approach was applied to a set of Landsat 5-TM and Landsat 7-EMT+ images to estimate the surface fluxes in the area. Three post-fire periods were analyzed, six, seven, nine, and 11 y…

Usability Challenges in Surgical Simulator Training

2009

Surgical virtual reality simulators have been taken into use in order to improve surgical skills training. Emergence of simulators increases the need for research and knowledge related to usability of medical simulators. In this study usability of laparoscopic surgical simulator was researched experimentally through combined analysis. Data was gathered with heuristic evaluation, questionnaires, and interviews as well as recorded simulator parameters. Results suggest that the surgical simulator could be more efficient learning and training tool if usability issues such as support and error prevention were reconsidered in more detail. There also seem to be grounds for connecting user support …
