Aspectos fonéticos y morfológicos de dos tratados del Corpus Hippocraticum

2002

Entre otras consideraciones, en este artículo se quieren poner de relieve algunos rasgos lingüísticos de los tratados hipocráticos De fistulis y De haemorrhoidibus, dentro del grupo de los tratados quirúrgicos de la Colección, con vistas a mostrar cómo se entreveran en ellos rasgos jónicos y áticos en dirección al griego helenístico. En nuestra opinión, estos tratados son obras de pleno siglo IV a. C., De haemorrhoidibus probablemente de mediados de siglo y De fistulis quizá algo anterior. Among other considerations, in this paper the author tries to point out some specific and linguistic features of the Hippocratic treatrises De fistulis and De haemorrhoidibus, both among the surgical trea…

Timing of the emergence of the Europe-Sicily bridge (40-17 cal ka BP) and its implications for the spread of modern humans

2014

The submerged sill in the Strait of Messina, which is located today at a minimum depth of 81 m below sea level (bsl), represents the only land connection between Sicily and mainland Italy (and thus Europe) during the last lowstand when the sea level locally stood at about 126 m bsl. Today, the sea crossing to Sicily, although it is less than 4 km at the narrowest point, faces hazardous sea conditions, made famous by the myth of Scylla and Charybdis. Through a multidisciplinary research project, we document the timing and mode of emergence of this land connection during the last 40 kyr. The integrated analysis takes into consideration morphobathymetric and lithological data, and relative sea…

Intrinsic generation of OH groups in dry silicon dioxide upon thermal treatments

2008

We show the existence of an intrinsic generation mechanism of OH groups in synthetic dry silica upon thermal treatments. Samples are treated for ~160 h at 390 °C in He at 2.7 or 180 bar, and the growth of the OH IR absorption band at 3670 cm−1 is observed. An OH concentration of ~10^18 cm^−3 is estimated. Possible contributions of reactions with molecules absorbed from the atmosphere are excluded. Reactions with H2O already contained in the samples are rejected by IR measurements. The observed OH generation is attributed to the reaction of network sites with H2 already present in the material. Possible reaction paths are examined

A test of transferability for landslides susceptibility models under extreme climatic events: application to the Messina 2009 disaster

2014

A model building strategy is tested to assess the susceptibility for extreme climatic events driven shallow landslides. In fact, extreme climatic inputs such as storms typically are very local phenomena in the Mediterranean areas, so that with the exception of recently stricken areas, the landslide inventories which are required to train any stochastic model are actually unavailable. A solution is here proposed, consisting in training a susceptibility model in a source catchment, which was implemented by applying the binary logistic regression technique, and exporting its predicting function (selected predictors regressed coefficients) in a target catchment to predict its landslide distribu…

Data Mining Technique (Maximum Entropy Model) for Mapping Gully Erosion Susceptibility in the Gorganrood Watershed, Iran

2019

Soil erosion is a serious problem affecting most of the countries. This study was carried out in Gorganrood Watershed (Iran), which extends for 10,197 km2 and is severely affected by gully erosion. A gully headcut inven- tory map consisting of 307 gully headcut points was provided by Google Earth images, field surveys, and national reports. Gully conditioning factors including sig- nificant geo-environmental and morphometric variables were selected as predictors. Maximum entropy (ME) model was exploited to model gully susceptibility, whereas the area under the ROC curve (AUC) and draw- ing receiver operating characteristic (ROC) curves were employed to evaluate the performance of the model.…

Hydrogeological hazards and weather events: Triggering and evolution of shallow landslides

2014

Abstract Landslides are the most intense and serious manifestations of the degradation of slopes and they are the main causes of geological hazard when they, directly or indirectly, involving towns and infrastructures. They are a global environment problem; there are several examples that have produced untold damages and loss of human lives in many parts of the world. In 1920 the landslides mobilization, as a result of a strong earthquake in China, in the province of Kansu, killed 200,000 people; in 1938 fast debris flow, triggered by heavy rainfalls in Japan, caused the death of 600 people; in 1963 in Italy the Vajont disaster caused the death of 1,899 people, as a result of a landslide lo…

Water erosion susceptibility mapping by applying Stochastic Gradient Treeboost to the Imera Meridionale River Basin (Sicily, Italy)

2016

Abstract Soil erosion by water constitutes a serious problem affecting various countries. In the last few years, a number of studies have adopted statistical approaches for erosion susceptibility zonation. In this study, the Stochastic Gradient Treeboost (SGT) was tested as a multivariate statistical tool for exploring, analyzing and predicting the spatial occurrence of rill–interrill erosion and gully erosion. This technique implements the stochastic gradient boosting algorithm with a tree-based method. The study area is a 9.5 km 2 river catchment located in central-northern Sicily (Italy), where water erosion processes are prevalent, and affect the agricultural productivity of local commu…

PROBLEMAS QUE CAUSAN INFERENCIAS MORFOSINTACTICAS ENTRE ITALIANO Y ESPANOL

2007

This paper’s purpose is to describe and analyze an error corpus due to interference between Italian and Spanish, produced by 20 Erasmus’s students in Palermo. Those students have studied Italian in their country, but they all have a basic language acquisition. Firstly, because of the affinity between the two languages, the acquisition of a basic competence could seem easily; subsequently it could be difficult to pass to an intermediate level, because of a phonetic, morphological and syntactical adaptation process. This paper aims to suggest an educational intervention trough the construction of an error’s file in which every student can put his own information. This method could be consider…
