A 'gateway city' between landscape and cultural heritage
2015
The paper analyzes the achievable strategic role that the porto of Porto Empedocle (sinergy by Agrigento, its "city mother") could have. This marginal city, localized in the center of the African side of the Sicily, is far from European politics, but this situation could change. It's necessary to improve the sea routes and to activate the disused railway line from Porto Empedocle to Castelvetrano (near Trapani). This solution will help the accessibility of Agrigento and the development of the little coastal towns organized in a slow and sustainable network. Lo scritto analizza il possibile ruolo strategico che il porto di Porto Empedocle (in sinergica con la sua città-madre, Agrigento). Que…
Yellow (577 nm) micropulse laser versus half-dose verteporfin photodynamic therapy in eyes with chronic central serous chorioretinopathy: results of …
2018
PurposeTo compare the functional and anatomical outcomes of eyes with chronic central serous chorioretinopathy treated with yellow micropulse (MP) laser versus half-dose verteporfin photodynamic therapy (PDT).MethodsThis is a multicentre, retrospective comparative study of 92 eyes treated with yellow MP laser (duty cycle of 5%, zero spacing between spots, spot size varied from 100 to 200 µm, power varied from 320 to 660 mW, and the pulse burst duration was 200 ms) and 67 eyes treated with PDT (half-dose verteporfin (3 mg/m2) infused over 10 min), followed by laser activation for 83 s. Spot sizes varied from 400 to 2000 µm.ResultsIn the MP group, at 12 months of follow-up, the mean best corr…
Volatiles in pantellerite magmas: A case study of the Green Tuff Plinian eruption (Island of Pantelleria, Italy)
2013
Abstract The Green Tuff (GT) Plinian eruption, the largest in magnitude at Pantelleria, erupted 3 to 7 km3 DRE of pantellerite magma and a small volume of trachyte. Fifty-nine anorthoclase-hosted melt inclusions from the two basal pumice members were analyzed by FT-IR spectroscopy in order to assess the pre-eruptive H2O content in the pantellerite melt. Microanalytical methods were used to determine major element, Cl, F and S contents. Melt inclusions and glassy groundmasses have a nearly homogeneous pantelleritic composition (peralkaline index = 1.9-2.2) and variable water contents ranging from 1.4 to as high as 4.2 wt %, i.e. much higher than the 1.4 wt % of earlier published studies. The…
Abuse of consumer trust in the digital market and the green market: the case of green washing in the Italian legal system
2022
Purpose The purpose of this paper is to offer some reflection on the abuse of consumer trust and the importance of control of information in the digital market and the green market. The role of the consumer as the arbiter of the market is fundamental. The abuse of consumer confidence depends, in fact, on the spread of stereotyped messages and vague and generic formulas aimed at hiding a dangerous vacuum of protection. In both markets, it is a question of giving the consumer the necessary tools to monitor the transparency of the criteria used by the trader to classify a product according to its characteristics. Design/methodology/approach Based on the analysis of an Italian case law and the…
A barium method for the cytochemical detection of sulfated glycosaminoglycans in mast cells and basophilic leukocytes.
1999
Barium ions precipitate inorganic as well as organic sulfate compounds and they can be detected by a reaction with sodium rhodizonate. In this work, we describe the use of a barium method for the selective demonstration of sulfated glycosaminoglycans in cytoplasmic granules of mast cells and basophilic leukocytes. Methanol-fixed smears of mouse peritoneal mast cells and rat bone marrow basophils were treated with 5% BaCl2 for 10 min, followed by staining with either 0.2% sodium rhodizonate in 50% ethanol for 2 h at 60 degrees C, or 0.01% brilliant green in distilled water for 1 min. Light microscopic observation revealed a strong staining reaction of the cytoplasmic granules of these cell t…

Environmental Sustainability Orientation, Reward-Based Crowdfunding, and Venture Capital: The Mediating Role of Crowdfunding Performance for New Tech…
2021
Extant literature has investigated the effects of new ventures’ environmental sustainability orientation (ESO) on the crowdfunding (CF) performance and on the ability to secure venture capital, separately and with mixed results. In this article, we address the study of these relationships simultaneously. Specifically, we examine how the presence of ESO features influences new technology-based ventures’ ability to secure funding in reward-based CF campaigns and how the CF performance mediates the effect of such features on attracting subsequent venture capital. Using a sample of new hardware ventures that have launched a CF campaign on Kickstarter, we document a negative effect of the presen…
Mechanical characterization of rose bengal and green light crosslinked collagen scaffolds for regenerative medicine
2021
Abstract Collagen is one of the most important biomaterials for tissue engineering approaches. Despite its excellent biocompatibility, it shows the non-negligible disadvantage of poor mechanical stability. Photochemical crosslinking with rose bengal and green light (RGX) is an appropriate method to improve this property. The development of collagen laminates is helpful for further adjustment of the mechanical properties as well as the controlled release of incorporated substances. In this study, we investigate the impact of crosslinking and layering of two different collagen scaffolds on the swelling behavior and mechanical behavior in micro tensile tests to obtain information on its wearin…
Novel Au NPs/Preyssler acid/TiO 2 nanocomposite for the photocatalytic removal of azo dye
2014
Abstract In this study, we introduced a novel nanocomposite consisting of Au nanoparticles decorated TiO 2 and Preyssler acid as a multifunctional photocatalyst linker molecule, in which gold ions reduced locally on the TiO 2 surface. The obtained nanocomposite has been characterized using Fourier Transform Infrared (FTIR), X-ray Diffraction (XRD), Electron Dispersive X-ray (EDX) Spectroscopy, Transmission Electron Microscopy (TEM) and Scanning Electron Microscope (SEM). Also, their photocatalytic activity has been studied for the degradation of model organic azo dye Malachite Green under UV light irradiation.
