Ad infantes terrendos. Sortilegi e disordine metamorfico nell'immaginario mitico greco sull'infanzia
2008
Le Lamie, le Empuse, e altre figure meno note come Ephialtes, Mormò, Gello appartengono a quello spazio rappresentativo centrato sulla maschera, veicolo di una potenza radicalmente altra che rimanda a se stessa: non sono precisamente né mito né fiaba, tuttavia esprimono una potente energia normativa rivolta a integrare nell'ordine sociale costituito. Nella loro qualità di horridae mulieres sono figure dell'instabilità e dei rischi occultati in ogni norma condivisa, figure della quotidianità esposta all'incertezza, al cedimento indotto dalla seduzione, ad un interminabile apprendimento di norme sempre in equilibrio tra memoria del passato e cambiamenti legati al futuro. Alimentando uno spazi…
Análisis del la relación del genotipado y marcadores de estrés oxidativo con la presencia y grado de vasculopatía periférica en pacientes con diabete…
2014
RESUMEN: Padecer diabetes tipo 2 (DM2) ejerce un efecto independiente y multiplicador en la incidencia de complicaciones vasculares, añadido a la presencia de factores de riesgo clásicos. No todos los diabéticos desarrollan con la misma gravedad la vasculopatía periférica (VP). Este riesgo está presente en la fase de prediabetes, donde las complicaciones vasculares pueden preceder a la aparición de la propia diabetes. La biología vascular ha puesto de manifiesto la participación de otros factores como el estrés oxidativo (EO) y el estado crónico inflamatorio en el incremento de este riesgo. Los principales sistemas conocidos de EO a nivel endotelial generan especies reactivas de oxígeno. Pa…
The influence of blue light on the Dionaea muscipula cultivation
2018
Rośliny wykorzystują światło jako źródło energii do fotosyntezy, reagują na jego intensywność, długość fali świetlnej i kierunek światła. Jest ono także swoistym sygnałem środowiskowym. Światło jest odbierane przez fotoreceptory roślin, takie jak: kryptochromy, fototropiny oraz fitochromy, a rośliny generują szeroki zakres specyficznych odpowiedzi fizjologicznych przez te receptory. Do badań wykorzystano dwie hodowle roślinne składające się z dwóch odmian muchołówki amerykańskiej - Dionaea muscipula: Regular form oraz Red green. Jedną z hodowli poddano oddziaływaniu światła niebieskiego, a drugą - kontrolną prowadzono w warunkach oddziaływania światła słonecznego. Prowadzono pomiary morfolo…
On multivalued weakly Picard operators in partial Hausdorff metric spaces
2015
We discuss multivalued weakly Picard operators on partial Hausdorff metric spaces. First, we obtain Kikkawa-Suzuki type fixed point theorems for a new type of generalized contractive conditions. Then, we prove data dependence of a fixed points set theorem. Finally, we present sufficient conditions for well-posedness of a fixed point problem. Our results generalize, complement and extend classical theorems in metric and partial metric spaces.
Landslide susceptibility zonation by exploiting GIS tools and two statistical methods: binary logistic regression and multivariate adaptive regressio…
2013
In the recent years advanced statistical methods and GIS tools have been frequently used to assess landslide susceptibility. The latter is estimated by establishing statistical relationships between landscape characteristics and spatial distribution of past slope-failures. These are mapped mainly by recognizing changes on slope morphology produced by gravity. Despite of this, most of the researches on landslide susceptibility do not consider that slope-failures modify topography and associate high probability of landsliding with topographic characteristics that differ from those that led slope-failures. In this research we analyzed landslide susceptibility in the basin of the Malvello river…
Assessment of Gully Erosion Susceptibility Using Multivariate Adaptive Regression Splines and Accounting for Terrain Connectivity
2017
In this work, we assessed gully erosion susceptibility in two adjacent cultivated catchments of Sicily (Italy) by employing multivariate adaptive regression splines and a set of geo-environmental variables. To explore the influence of hydrological connectivity on gully occurrence, we measured the changes of performance occurred when adding one by one nine predictors reflecting terrain connectivity to a base model that included contributing area and slope gradient. Receiver operating characteristic (ROC) curves and the area under the ROC curve were used to evaluate model performance. Gully predictive models were trained in both the catchments and submitted to internal (in the calibration cat…
Predicting Earthquake-Induced Landslides by Using a Stochastic Modeling Approach: A Case Study of the 2001 El Salvador Coseismic Landslides
2023
In January and February 2001, El Salvador was hit by two strong earthquakes that triggered thousands of landslides, causing 1259 fatalities and extensive damage. The analysis of aerial and SPOT-4 satellite images allowed us to map 6491 coseismic landslides, mainly debris slides and flows that occurred in volcanic epiclastites and pyroclastites. Four different multivariate adaptive regression splines (MARS) models were produced using different predictors and landslide inventories which contain slope failures triggered by an extreme rainfall event in 2009 and those induced by the earthquakes of 2001. In a predictive analysis, three validation scenarios were employed: the first and the second …
Factor selection procedures in a Google Earthtm aided landslide susceptibility model: application to the Beiro river basin (Spain)
2011
A procedure to select the controlling factors connected to the slope instability has been defined. It allowed to assess the landslide susceptibility in the Rio Beiro basin (about 10 km2) over the north-eastern area of the city of Granada (Spain). Field and remote (Google EarthTM) recognition techniques allowed to generate a landslide inventory consisting in 127 phenomena. Univariate tests, using both association coefficients and validation results of single parameter susceptibility models, allowed to select among 15 controlling factors the ones that resulted as good predictor variables; these have been combined for unique conditions analysis and susceptibility maps were finally prepared. In…
