Typhetum laxmannii (Ubrizsy 1961) Nedelcu 1968 - The new plant association in Poland
2011
<em>Typhetum laxmannii</em> (Ubrizsy 1961) Nedelcu 1968 is a plant association new to Poland, built by an expansive kenophyte - <em>Typha laxmannii</em> Lepech. This paper presents the general distribution of both, the species and the association, paying particular attention to the area of Europe and Poland where, in recent years, many new locations as well as an increasing participation in vegetation cover have been observed. The habitat preferences of <em>Typhetum laxmannii</em>, the floristic composition of the association and its geographical differentiation within the occupied area are described. The current distribution of the association in Poland …
Accesibilidad y provisión de servicios de interés general en las áreas rurales de la Unión Europea: un análisis a partir del Eurobarómetro
2014
La finalidad de este trabajo es ofrecer un estado de la cuestión sobre el acceso y provisión de Servicios de Interés General (SeIG) en las áreas rurales de la Unión Europea. Se identifican fuerzas de cambio, oportunidades y dificultades relativas a los SeIG que pueden contribuir a impulsar o ralentizar los procesos de desarrollo rural. Se lleva a cabo una revisión de las principales aproximaciones teóricas y se presentan diversos análisis empíricos a partir de los escasos datos homogéneos disponibles. A partir del conocimiento adquirido se formula un conjunto de reflexiones sobre la función de los SeIG en los procesos de cambio rural en la UE.
Distributed and Lumped Parameter Models for the Characterization of High Throughput Bioreactors
2016
Next generation bioreactors are being developed to generate multiple human cell-based tissue analogs within the same fluidic system, to better recapitulate the complexity and interconnection of human physiology. The effective development of these devices requires a solid understanding of their interconnected fluidics, to predict the transport of nutrients and waste through the constructs and improve the design accordingly. In this work, we focus on a specific model of bioreactor, with multiple input/outputs, aimed at gen- erating osteochondral constructs, i.e., a biphasic construct in which one side is cartilagi- nous in nature, while the other is osseous. We next develop a general computat…
An integrated geodetic and InSAR technique for the monitoring and detection of active faulting in southwestern Sicily
2020
We present the results of the analysis of GNSS (Global Navigation Satellite System) and InSAR (Interferometric synthetic-aperture radar) data collected in the frame of a project financed by the “Struttura Terremoti” of INGV (Istituto Nazionale di Geofisica e Vulcanologia). Combined investigations pointed out for potential seismogenic sources for destructive earthquakes recorded in southwestern Sicily, including the 1968 Belice earthquake sequence and that supposed to have destroyed the Greek city of Selinunte which, according to geoarcheological data experienced two earthquakes in historical times. Our approach is aimed to evaluate the current deformation rate in SW Sicily and to improve th…
Pagine di geografia, pagine di vita
2020
Il capitolo analizza una parte della produzione scientifica di Girolamo Cusimano, professore ordinario di Geografia presso l'Università di Palermo. In particolare, attraverso una selezione di testi significativi, vengono ripercorsi sia il posizionamento dello studioso nel dibattito sul complesso rapporto tra paesaggio e letteratura in seno alla Geografia umana e culturale tra la fine degli anni Novanta e l'inizio degli anni Duemila, sia il suo contributo alla discussione teorica sulla cartografia.
El uso de SIG de software libre en una práctica de Biología y Geología de 4º de ESO: los ecosistemas.
2016
Para consolidar el conocimiento del bloque del currículo de Biología y Geología de 4º de la E.S.O. (Educación Secundaria Obligatoria) relacionado con los ecosistemas, hemos desarrollado una metodología docente basada en los Sistemas de Información Geográfica (SIG), en la que el objetivo de los estudiantes es crear un shapefile con atributos espaciales e información ecológica sobre los distintos Parques Nacionales de España mediante su digitalización. Se ejemplifica con el procedimiento concreto del Parque Nacional de Doñana. A través del SIG, con un software gratuito para el centro, se aumenta la interactividad del estudiante con la asignatura, se desarrolla la creatividad y se mejora la ca…
Proposal of a Geographic Information System for modeling zoonotic fasciolosis transmission in the Andes
2004
ABSTRACT The present study describes the basis for the development of a Geographic Information System(GIS) for conducting an epidemiological analysis of human and animal fasciolosis in the Andes. Themethodology proposes the use of various data bases - those derived from epidemiologicalmutidisciplinary studies and environmental data derived from terrestrial stations and remote sensing. Key words : Fasciola hepatica, fasciolosis transmission, Andes, geographic information system,model. INTRODUCTIONOver the last decade, the importance of humanand animal fasciolosis in various south Americancountries has been emphasized in the scientificliterature 1-5 ; indeed, human infection by Fasciolahepati…
Modelling the spatial-temporal progression of the 2009 A/H1N1 influenza pandemic in Chile
2016
A spatial-temporal transmission model of 2009 A/H1N1 pandemic influenza across Chile, a country that spans a large latitudinal range, is developed to characterize the spatial variation in peak timing of that pandemic as a function of local transmission rates, spatial connectivity assumptions for Chilean regions, and the putative location of introduction of the novel virus into the country. Specifically, a metapopulation SEIR (susceptible-exposed-infected-removed) compartmental model that tracks the transmission dynamics of influenza in 15 Chilean regions is calibrated. The model incorporates population mobility among neighboring regions and indirect mobility to and from other regions via th…
Study and 3D survey of the Roman baths in the archaeological site of Lylibaeum (Marsala, Italy)
2020
Abstract Archaeological documentation is a fundamental step for research and conservation planning phases. Nowadays traditional recording is always supported by geomatics technologies which offer important support to the growth of archaeological study. The integration of sensors and methodologies seems to give the best results, in terms of time, costs and accuracy of products. In particular, the combination of Terrestrial Laser Scanner (TLS) and Unmanned Aerial Vehicle (UAV) can help the documentation of complex sites and the production of 3D and 2D products for different purposes. The paper focuses on the integration of TLS and UAV methodologies to record the thermal baths of the Roman Dom…
Estimación de la fAPAR sobre la Península Ibérica a partir de la inversión del modelo de transferencia radiativa 4SAIL2
2014
El objetivo de este trabajo consiste en la estimación de la fAPAR en la Península Ibérica a partir de datos MODIS. En primer lugar, se ha simulado un conjunto de datos de reflectividades y de fAPAR a partir de los modelos de transferencia radiativa de hoja (PROSPECT) y de cubiertas heterogéneas (4SAIL2). En segundo lugar, se ha entrenado un conjunto de redes neuronales artificiales (RNAs) para obtener mediante inversión la relación entre la fAPAR y las reflectividades simuladas y así calcular, por último, la fAPAR de la Península Ibérica a partir de imágenes de reflectividad de MODIS. Además, se ha analizado la influencia de la configuración de observación e iluminación, nadir y oblicua. La…
