Ambiente e clima della Sicilia durante gli ultimi 20 mila anni
2010
Environment and Climate in Sicily over the last 20, 000 years. (IT ISSN 0394-3356, 2010). A series of recent studies shed light on the central Mediterranean, and Sicily, climate and environment, starting from the last glacial maximum (about 20 ka cal BP). In the present paper, we examine most of these works, in order to unravel environmental changes of the past, mainly in terms of temperature, atmospheric pattern, precipitation, vegetation and faunal associations. The climate of the last glacial maximum was characterised by very low temperature and by repeated northerlies penetration, even during summer. Low precipitation values led to a steppe- or semisteppe-like vegetation pattern, domina…

Added-Mass Based Efficient Fluid–Structure Interaction Model for Dynamics of Axially Moving Panels with Thermal Expansion
2020
The paper considers the analysis of a traveling panel, submerged in axially flowing fluid. In order to accurately model the dynamics and stability of a lightweight moving material, the interaction between the material and the surrounding air must be taken into account. The lightweight material leads to the inertial contribution of the surrounding air to the acceleration of the panel becoming significant. This formulation is novel and the case complements our previous studies on the field. The approach described in this paper allows for an efficient semi-analytical solution, where the reaction pressure of the fluid flow is analytically represented by an added-mass model in terms of the panel…

Development of fast analysis methods for extractives in papermaking process waters
2011
A fast analysis method with an online sample enrichment technique for the analysis of resin and fatty acids present in papermaking process waters was developed. This method was based on atmospheric pressure chemical ionization (APCI) and mass spectrometry (MS) for the detection of [M-H]- ions of compounds of interest. The method was applied to the control of the most prevalent resin (dehydroabietic and abietic) and fatty (palmitic, stearic, oleic, and linolenic) acid levels in papermaking process waters. Continuous data on these acids are of practical importance when predicting possible deposit-derived problems in the paper machine. The first part of the study was focused on the development…
A CNN Adaptive Model to Estimate PM10 Monitoring
2006
In this work we introduce a model for studying the distribution and control of atmospheric pollution from PM10. The model is based on the use of a cellular neural network (CNN) and more precisely on the integration of the mass-balance equation; at the same time it simulates the scenario regarding a planar grid describing the whole studied area (the city of Palermo) by means of a CNN and a set of Bayesian networks. The CNN allows us to define a grid system whose dynamic evolution is a redefinition of the diffusion equation that considers contributions coming from near cells for each element of the grid. Dynamics of each cell is influenced by meteorological effects and by parameters related t…
SICILY: THE OVERWHELMING FLUXES OF MASS TOURISM, IMMIGRATION AND STREET MARKETS
2016
Tre progetti sono sviluppati nello stupendo, sebbene in parte distrutto, centro storico di Palermo, il quarto si trova invece ad Agrigento sulla costa sud ovest della Sicilia, un sito archeologico di rinomanza mondiale. Lo scenario di questi progetti è la Sicilia dei prossimi anni nella quale enormi masse di persone arriveranno. - Da un lato il turismo di massa con il suo straripante sviluppo porterà gente al Nord - principalmente Palermo – e loro molto spesso si dirigeranno a Sud a vedere le rovine greche. - similmente una latrettanto enorme massa di gente disperata sbarcherà avventurosamente sulla costa sud e farà lo stesso percorso ma in verso opposto verso Palermo, tappa intermedia vers…
Production and Characterization of Medium-Sized and Short Antioxidant Peptides from Soy Flour-Simulated Gastrointestinal Hydrolysate.

Soybeans (Glycine max) are an excellent source of dietary proteins and peptides with potential biological activities, such as antihypertensive, anti-cholesterol, and antioxidant activity
Digital resources in the current journalistic narrative: Uses and limitations of hypertext, multimedia and interactivity
2020
Characterised by its multilingual and multiformat features, the multimedia journalism narrative is shaping a new ‘archaeology of composition’ (Manovich, 2005), also called the ‘new textuality’ (Anichini, 2003). As digital media celebrates its 25th anniversary (Salaverría, 2019), this research aims to examine the current state of the multimedia narrative in journalism. The defining elements of this narrative in the generalist information media have been analysed through the observation of hypertextual, multimedia and interactive resources. The methodology used is content analysis, allowing for both the systemization and description of the predominant parameters through the comparative study …
Carbon biomass planktonic-periphytic organisms of a mesocosm experiment [Dataset]
2020
Este documento presenta los datos de biomasa en carbono (mgC m-2) de taxones planctónicos y perifíticos de un experimento a escala de mesocosmos. La comunidad planctónica-perifítica fue sometida a tres escenarios de cambio global, con la temperatura y la radiación ultravioleta como factores experimentales testados independientemente. Cada elemento de la comunidad fue identificado a la máxima resolución taxonómica posible. Las abreviaciones y explicaciones sobre los escenarios experimentales, las replicas de cada escenario y los detalles de los compartimentos considerados en cada mesocosmos se muestran en la primera página de este documento. This document presents the data about carbon bioma…
