Educare alla sostenibilità. Percezioni e rappresentazioni del cambiamento climatico nella scuola secondaria di II grado: i casi di Palermo e Catanzar…
2021
Questo contributo propone uno studio sulle modalità di percezione del cambiamento climatico da parte dei giovani di età compresa tra i 16 e i 20 anni che vivono nei capoluoghi di due città del Sud Italia, Palermo, capoluogo della Sicilia e Catanzaro, capoluogo della Calabria. Attraverso interviste etnografiche, basate sull’utilizzo di un questionario aperto e sull’osservazione partecipante condotta in due scuole secondarie di secondo grado (una per ogni regione succitata), si è cercato di ricostruire il grado di consapevolezza degli studenti intervistati rispetto al cambiamento climatico in atto, chiedendo loro di indicare quali siano le forme di conoscenza implicate, le possibili cause del…

Gli albori dell'indagine contemporanea in Calabria: le botteghe d'arte tra Biennale ed Expo
2012
Attraverso l'esperienza delle botteghe calabresi alle Biennali Internazionali di Arte Applicata a Monza nelle tre edizioni del 1923,1925,1927, si indagano i linguaggi e le forme proprie dell'artigianato artistico della regione. Cercando una comparazione nelle arti applicate e in generale in quel gusto folklorico e popolare, si mette in luce come la partecipazione alle Biennali di Monza sia stato un momento di apertura e commistione dei linguaggi. il tutto all'interno di un contesto storico ed economico definito come quello calabrese.

Tecniche costruttive antisismiche in Calabria tra la fine dell'Ottocento e l'inizio del Novecento,
2016
La presente memoria intende indagare lo sviluppo delle costruzioni antisismiche in Calabria in un periodo compreso tra gli anni Ottanta dell'Ottocento e i primi anni del Novecento. Lo studio è incentrato sulle tecniche costruttive adottate nelle ricostruzioni post-terremoto realizzate in un periodo immediatamente antecedente il sisma che colpì Messina e Reggio Calabria nel 1908, dopo il quale si registra un progressiva affermazione della tecnologia del cemento armato. In questo arco cronologico si assiste a un notevole sviluppo degli studi nel campo della costruzione antisismica, con una prevalente riproposizione di sistemi costruttivi tradizionali e con le prime sperimentazioni sul cemento…

Rapid transformation of inorganic to organic and plant-available phosphorous in soils of a glacier forefield
2012
Abstract Chemical weathering of rocks or sediments is extremely important for the generation of soils, for the evolution of landscape, and as a main source of inorganic nutrients for plant growth and therefore for life. Temporal trends in weathering mechanisms, plant succession and nutrients availability in cold environments can be successfully studied in soil chronosequences along a glacier forefield. In the present paper, this was carried out in the pro-glacial area of Morteratsch. Different forms of phosphorous in the soil, stream and spring water chemistry were investigated. Apatite constitutes the main source of P, but it occurs only as a minor accessory mineral phase in the granitic/g…
PHEA-graft-polymethacrylate supramolecular aggregates for protein oral delivery
2013
Abstract Salmon calcitonin (sCT) is characterized by a poor oral availability. A new copolymer, β-poly(N-2-hydroxyethyl)-graft-{N-2-ethylene[2-poly(methacrylic acid sodium salt)isobutyrate]}- d , l -aspartamide (PHEA-IB-p(MANa + )), was designed for the oral administration of sCT through the formation of supramolecular aggregates (SAs) based on electrostatic interactions. Several sCT/PHEA-IB-p(MANa + ) weight ratios were characterized by turbidimetry, DLS, zeta potential, and microscopy analysis. After the incubation of sCT/PHEA-IB-p(MANa + ) complex with digestive enzymes, 10% (w/w) of loaded sCT was released in the native form. In vitro investigation was carried out to determine the copol…
Short time guided bone regeneration using beta-tricalcium phosphate with and without fibronectin. An experimental study in rats
2020
Background The aim of this histomorphometric study was to assess the bone regeneration potential of beta-tricalcium phosphate with fibronectin (β-TCP-Fn) in critical-sized defects (CSDs) in rats calvarial, to know whether Fn improves the new bone formation in a short time scope. Material and Methods CSDs were created in 30 Sprague Dawley rats, and divided into four groups (2 or 6 weeks of healing) and type of filling (β-TCP-Fn, β-TCP, empty control). Variables studied were augmented area (AA), gained tissue (GT), mineralized/non mineralized bone matrix (MBM/NMT) and bone substitute (BS). Results 60 samples at 2 and six weeks were evaluated. AA was higher for treatment groups comparing to …
Calcium bioavailability in human milk, cow milk and infant formulasâcomparison between dialysis and solubility methods
1999
Abstract The percentages of total, soluble and dialysable calcium of human milk, cow milk and milk and soy based infant formulas were determined in order to detect possible differences in the calcium bioavailability of the samples. For this purpose an in vitro method was applied to these four calcium sources. The ranking of the analysed samples in terms of calcium bioavailability depends on the criteria applied. Calcium ranked dialysis percentage was: cow milk>human milk>soy based formula>milk based formulas. Calcium ranked solubility percentage was: human milk>cow milk>soy-based formula>milk-based formulas. Comparison of the results of the in vitro assay with the information available on i…
