La coltivazione del tartufo in Sicilia: risultati preliminari
2011
In recent times truffles were found in several natural forest ecosystems and reaforestation of Sicily. On the basis of these findings a number of research projects were activated. In the framework of an agreement between the Laboratory of Mycology of the Department of Botany (University of Palermo) and the Farm "Buontempo-Le Due Sicilie", located in the territory of the Madonie Natural Park, a first attempt to cultivate truffles of economic importance were carried out. In the spring of 2006 the experimental truffle-bed was developed on the basis of 100 seedlings of Corylus avellana L. inoculated with Tuber aestivum Vitt. (80%) and T. melanosporum Vittad. (20%). Besides 110 seedlings of Quer…
Multitemporal water quality study in Sitjar (Castelló, Spain) reservoir using Sentinel-2 images
2020
[EN] Water quality is a subject of intense scientific inquiry because of its repercussion in human’s life, agriculture or even energy generation. Remote sensing can be used to control water masses by analyzing biophysical variables. Chlorophyll-a (Chl-a) and Total Suspended Solids (SS) are a well-known feature of water quality. These variables have been measured in Sitjar reservoir (Castelló, Spain) as a part of the project Ecological Status of Aquatic Systems with Sentinel Satellites (ESAQS), in order to compare the results with satellite reflectance data. Two processes were compared to correct atmospherically the level 1C Sentinel 2 (S2) images. The results show that Case 2 Regional Coast…
Analysing longitudinal turbulence intensity in vegetated channels
2007
Vegetation altering hydrodynamic conditions of an open channel flow controls the exchanges of sediment, nutrients and contaminants. In this paper the turbulence structure of open-channel flow over a flexible grass vegetation is investigated. Velocity measurements were carried out, in a rectangular flume, using a 2D-ADV (Acoustic Doppler Velocimeter) for different values of stem concentration, water discharge, and bed slope. The experimental results showed that: 1) the maximum value of the longitudinal turbulence intensity occurs at a water depth close to the bent vegetation height; 2) the turbulence intensity damps for increasing values of the stem concentration; 3) above the vegetation hei…
Anche quella foto acquistò colore
2019
È una raccolta di considerazioni pedagogiche radicate in episodi reali ambientati nella Palermo degli anni 90; è l’esempio di come può nascere l’interesse per la ricerca scientifica in ambito pedagogico in seguito ad alcune esperienze di tutoring universitario svolto in modo riflessivo. Un testo che può aiutare molto gli studenti, specialmente nei loro primi mesi di impatto iniziale con la realtà accademica. L’approccio è accattivante, incuriosisce, attira l’attenzione del giovane ventenne perché comunica idee positive sullo studio e sulle relazioni interpersonali mediante brevi, ma frequenti, riflessioni sullo studio universitario.
Influence of geographical extent on typology- and model-based assessments of taxonomic completeness of river macroinvertebrates
2009
Summary 1. River InVertebrate Prediction and Classification System (RIVPACS)-type predictive models are increasingly used to assess the biological condition of freshwaters, but management schemes may also be based on a priori groupings of similar water bodies (typologies) to control for natural variation in biota. The two approaches may lead to disagreements of the biological status of a site, depending on, for example, the spatial scale at which assessments are conducted. 2. We used data from 96 reference and 134 potentially impacted sites from Western and Central Finland to compare RIVPACS-type models and a simple size-based typology of rivers for the assessment of taxonomic completeness …
Decidir reflexivamente. Un estudio sobre reflexividad y trayectorias formativas en estudiantes de postgrado
2017
Las trayectorias formativas y profesionales de los jóvenes están actualmente cargadas de incertidumbre y no discurren de manera lineal. Atrás han quedado los tiempos en que acceder a la universidad significaba garantía de empleo para el futuro y el inicio de itinerarios profesionales más definidos. A partir de una investigación en la que se ha entrevistado a estudiantes de postgrado de dos universidades públicas se analiza cómo se configuran las trayectorias formativas y las expectativas laborales a través del concepto de reflexividad siguiendo la aplicación que propone Margaret S. Archer. El resultado es una triple tipología de reflexividad que presenta las decisiones educativas como compa…
The Relation Between Stretching Typology and Stretching Duration: The Effects on Range of Motion.
2018
AbstractDifferent stretching strategies and protocols are widely used to improve flexibility or maintain health, acting on the muscle tendon-unit, in order to improve the range of motion (ROM) of the joints. This review aims to evaluate the current body of literature in order to understand the relation between stretching typology and ROM, and secondly to evaluate if a relation exists between stretching volume (either as a single training session, weekly training and weekly frequency) and ROM, after long-term stretching. Twenty-three articles were considered eligible and included in the quantitative synthesis. All stretching typologies showed ROM improvements over a long-term period, however…
Perturbaciones macroeconómicas, políticas de ajuste y adaptabilidad del mercado de trabajo ante la uem
2000
Este artículo describe la situación del mercado de trabajo y analiza las causas del desempleo en Europa. En él se pasa revista a las políticas de ajuste que están en manos de los países miembros de la zona euro ante perturbaciones macroeconómicas y se discuten los problemas de ajuste en los mercados de trabajo europeos en el marco de la Unión Económica y Monetaria. Se propone un nuevo concepto de «flexibilidad» del mercado de trabajo que vaya más allá de la actual medición del «rigor» de la legislación sobre las condiciones de contratación y despido y que recoja también las características más estructurales del mercado de trabajo, como los skill gaps, la capacidad para utilizar nuevas tecno…

Onomatopeya, imitación y poesía en Grecia y Roma
2019
A partir de Platón se desarrolla en la reflexión gramatical y filosófica griega la idea de que ciertos vocablos tienen un origen onomatopéyico, tomándose como modelo de su uso (tanto por su conveniencia como por su condena) su aparición en el epos homérico. Mientras la filosofía vinculará tales palabras, entendidas como onomatopeyas, al origen del lenguaje, los autores de poética y gramática las estudiarán como elementos significativos en la valoración estética de la poesía. La doctrina griega sobre la onomatopeya pasará, a su vez, a las letras latinas.
