Risk assessment of gypsum amendment on agricultural fields: Effects of sulfate on riverine biota
2022
Gypsum (CaSO4 ∙ 2H2 O) amendment is a promising way of decreasing the phosphorus loading of arable lands, and of thus preventing aquatic eutrophication. However, in freshwaters with low sulfate concentrations, gypsum-released sulfate may pose a threat to the biota. To assess such risks, we performed a series of sulfate toxicity tests in the laboratory and conducted field surveys. These field surveys were associated with a large-scale pilot exercise involving spreading gypsum on agricultural fields covering 18% of the Savijoki River catchment area. The gypsum amendment in such fields resulted in about fourfold increase in the mean sulfate concentration for a 2-month period, and a transient, …
Bio-predictive tablet disintegration: Effect of water diffusivity, fluid flow, food composition and test conditions
2013
Abstract Food intake may delay tablet disintegration. Current in vitro methods have little predictive potential to account for such effects. The effect of a variety of factors on the disintegration of immediate release tablets in the gastrointestinal tract has been identified. They include viscosity of the media, precipitation of food constituents on the surface of the tablet and reduction of water diffusivity in the media as well as changes in the hydrodynamics in the surrounding media of the solid dosage form. In order to improve the predictability of food affecting the disintegration of a dosage form, tablet disintegration in various types of a liquefied meal has been studied under stati…

Small-sized granules of biphasic bone substitutes support fast implant bed vascularization
2015
The present study investigated the influence of granule size of 2 biphasic bone substitutes (BoneCeramic® 400-700 μm and 500-1000 μm) on the induction of multinucleated giant cells (MNGCs) and implant bed vascularization in a subcutaneous implantation model in rats. Furthermore, degradation mechanisms and particle phagocytosis of both materials were examined by transmission electron microscopy (TEM). Both granule types induced tissue reactions involving primarily mononuclear cells and only small numbers of MNGCs. Higher numbers of MNGCs were detected in the group with small granules starting on day 30, while higher vascularization was observed only at day 10 in this group. TEM analysis reve…
TESTIMONI PRIVILEGIATI NEI CASI DI VIOLENZA: DALLE PAROLE DELLO SVELAMENTO AGLI INTERVENTI DI PROTEZIONE
2011
Lo studio analizza la questione della risonanza emotiva e dei conseguenti atteggiamneti degli operatori delle Forze dell'Ordine durante gli interrogatori di presunte vittime di abuso. Il contributo riferisce alcune significative osservazioni scaturite dalla somministrazione di due strumenti (un'intervista ed un questionario) a 9 "testimoni privilegiati" che vivono l'esperienza del primo resoconto del bambino e che rappresentano vari corpi delle Forze dell'Ordine delle città di Palermo e di Trapani. La ricerca dimostra la necessità di un percorso di formazione che aiuti gli operatori a mettere in atto modalità efficaci nell'accogliere il minore e nel raccoglierne la storia, costruendo un cli…
Forme e retoriche del fototesto letterario
2016
In ciò che tradizionalmente chiamiamo letteratura esistono forme che definiamo fototesti. Nella loro ormai secolare storia – che di fatto inizia a pochi decenni dall’invenzione della fotografia con il testo di Georges Rodenbach, Bruges la morta (Bruges-la-Morte, 1892) – la teoria letteraria ha avuto costante difficoltà anche semplicemente ad accettarne l’esistenza tra le forme alte di letteratura (per non dire nel canone), preferendo per lo più relegare questi ibridi tra le forme giornalistiche, quando addirittura non ne ha negato l’esistenza amputando l’immagine dal testo e viceversa.
Mechanical properties of basalt fiber reinforced composites manufactured with different vacuum assisted impregnation techniques
2016
Abstract This work describes an experimental mechanical characterisation campaign on composites made out of a quasi-unidirectional basalt fabric. In order to evaluate the ability of commercial basalt fabrics and their composites to meet the potentials of basalt fibers, the work has used raw materials from commercial catalogs with no further modification. Two common manufacturing techniques for medium performance composites have been adopted: vacuum assisted resin infusion, and hand-impregnated vacuum bagging. Two panels, one for each technique, have been fabricated, able to provide a sufficient number of samples for a comprehensive stiffness and strength characterization through Tensile, Fl…
