Pollutant removal efficiency of a pilot-scale Horizontal Subsurface Flow in Sicily (Italy) planted with Cyperus alternifolius L. and Typha latifolia …
2016
Constructed wetland systems (CWs) are developed biological technologies for the treatment and reuse of wastewater. The aims of this study were to evaluate the treatment performance of a pilot Horizontal Subsurface Flow system (HSSFs), to evaluate the reuse of treated wastewater (TWW) from CWs for the irrigation of giant reed (Arundo donax (L.)) and to assess the effects of TWW on the biomass yield of giant reed grown for pellet production. The research was carried out in Sicily (Italy) in a pilot-scale HSSFs which was fed with urban-treated urban wastewater following secondary treatment from an activated sludge wastewater treatment plant. Giant reed plots were irrigated with TWW from plante…
On the product of balanced sequences
2011
The product w = u ⊗ v of two sequences u and v is a naturally defined sequence on the alphabet of pairs of symbols. Here, we study when the product w of two balanced sequences u,v is balanced too. In the case u and v are binary sequences, we prove, as a main result, that, if such a product w is balanced and deg ( w ) = 4, then w is an ultimately periodic sequence of a very special form. The case of arbitrary alphabets is approached in the last section. The partial results obtained and the problems proposed show the interest of the notion of product in the study of balanced sequences.
Sustainable service-learning in Physical Education teacher education: examining postural control to promote ASD children’s well-being
2021
As classrooms become more and more diverse, it is imperative to provide physical education teacher education (PETE) students with opportunities to develop competencies that promote quality education for all students. In this study, PETE students applied a physical education servicelearning (SL) program aimed at enhancing Autism Spectrum Disorder (ASD) children’s motor domain and general well-being—objectives that are connected to the third focus of the United Nations’ Sustainable Development Goals (SDGs). Traditionally, research on SL has focused on students’ outcomes, and there is a call to examine SL’s effects on service receivers, which is the gap this paper aspires to fill. The aim of t…
From the old agroforestry systems of the modern high-density olive groves: which Carbon sequestration?
2019
Olive tree (Olea europaea L) represents one of the most important evergreen tree species. In Sicily agroforestry systems based on the olive tree, named traditional olive orchard, are common and often are grown together to other tree crops, such as vineyards, or with cereals or forages. This last are usually grown in the interspace between rows and particularly in olive groves were planting density is rather low (less than 200 trees/ha). To increase crop efficiency and to reduce costs of harvesting, by using proper machines, in the last 20 years in the olive industry have been developed new planting systems: Intensive (up to 400 trees/ha), and the Superintensive (up to 2000 trees/ha). Within…
Multiple Non-linear Reservoirs to Model Water Balance Components in Sandy Soils
2023
In the hydrologic literature, to model water flow in unsaturated soils, the Richards equation is usually applied, allowing the main components of the hydrologic cycle, as rainfall partitioning into surface runoff and infiltration, to be determined. The Richards equation is highly nonlinear, making very challenging to derive analytical solutions. Recently, for constant rainfall intensity, under the simplified hypothesis of gravity-driven infiltration, and by assuming a capacitance framework, a simplified solution of the Richards equation that considers the Brooks and Corey hydraulic conductivity function was suggested. By maintaining the assumption that the infiltration process is dominated …
L'incremento della sostenibilità ambientale attraverso una corretta gestione dell'irrigazione.
2014
Lo scopo di questo lavoro è quello di mettere a punto, a partire dalle informazioni territoriali quali caratteristichemeteorologiche e pedologiche, uno studio capace di valutare la sostenibilità della gestione irrigua in tre ipotetiche parcelle sperimentali individuate nel territorio del sottobacino Iudeo-Bucari (TP). Sitratta di tre vigneti che rappresentano per caratteristiche morfologiche e gestionali l'intero sottobacino, ovvero una delle aree maggiormente vitate della Sicilia. Il fine è valutare la sostenibilità della gestione irrigua in termini di risparmio energetico, attraverso l'applicazione del modello di bilancio idrico FAO 56. Questo tipo di studio pone le basi per la redazione …

Emerging Immnunohistochemical evidence for Direct Peripheral Control of Endocannabinoids on the Gastrointestinal Tract and Pancreas of Obese (fa/fa)a…
2012
This research has the objective to investigate immunohistochemical expression of CB1 receptor and its probable changes in Gastroenteropancreatic system (GEP) of obese and lean Zucker rats and understand the endocannabinoid pathophysiological implications in the obesity. Male obese (fa/fa) and lean Zucker rats 6 weeks old were obtained from Harlan Italy Srl; the rats were sacrificed at 8, 12 and 16 weeks old. Normal rats also were sacrificed. Specimens of stomach, jejunum-ileum and pancreas were fixed in Bouin’s mixture and embedded in paraffin; obtained sections were processed with anti-CB1 (Biosource Europe SA) by Streptavidin-Biotin-Complex Method. The findings show that CB1 receptor is e…
MODELLING WATER AND ENERGY BALANCE OF THE LAND-ATMOSPHERE SYSTEM USING HIGH RESOLUTION REMOTE SENSING DATA
2011
La rilevanza assunta dal risparmio della risorsa idrica negli ultimi anni ha spinto verso una corretta quanti cazione delle perdite legate al processo evapotraspirativo, al ne di una gestione parsimoniosa della risorsa stessa. In particolare nei sistemi agricoli soggetti a stress severo, sia la misura che la stima dell'evapotraspirazione (ET) ad un'adeguata risoluzione spaziale e temporale sono uno dei principali problemi da a rontare per la comunit a scienti ca. Recentemente, le tecniche di telerilevamento sono divenute un ulteriore strumento a supporto della modellistica idrologica distribuita; in particolare, le immagini acquisite nelle onde corte e nell'infrarosso termico risultano esse…
