Green roof effects on the rainwater response in the Mediterranean area: first results of a Sicilian case study
2021
<p>Over the last decades, we have been witnessing an increasing frequency of urban floods often attributed to the interaction between intensification of rainfall extremes due to climate change and increasing urbanization. Consequently, many studies have been trying to propose different new alternatives to mitigate ground effects of ever more frequent and severe extreme rainfall events in a context of growing urbanization, such as rain gardens, green roofs, permeable parking lots, etc., which are commonly referred to as green infrastructures.</p><p>With this regard, one of the most promising mitigation solutions is represented by multilayer green roo…
Hyperspectral LCTF-based system for classification of decay in mandarins caused by Penicillium digitatum and Penicillium italicum using the most rele…
2013
[EN] Green mold (Penicillium digitatum) and blue mold (Penicillium italicum) are important sources of postharvest decay affecting the commercialization of mandarins. These fungi infections produce enormous economic losses in mandarin production if early detection is not carried out. Nowadays, this detection is performed manually in dark chambers, where the fruit is illuminated by ultraviolet light to produce fluorescence, which is potentially dangerous for humans. This paper documents a new methodology based on hyperspectral imaging and advanced machine-learning techniques (artificial neural networks and classification and regression trees) for the segmentation and classification of images …
THE MEDITERRANEAN'S GOLD: WHICH COMMERCIAL PROSPECTS FOR THE THUNNUS THYNNUS IN ITALY?
2019
By taking into consideration the relevant role, in the international trade of Bluefin Tuna (Thunnus thynnus), played by Italy, aim of this work is assess the change in the Italian competitive advantage in the international market over the last decade (2008/2017), as a consequence of the Total Allowable Catch system together with size limits set by the International Commission for the Conservation of Atlantic Tunas (ICCAT). Investigating the main changes occurred in the Italian international trade balance, by focusing the attention on the relations with the main commercial partners operating in this industry, is of relevant importance to make available updated data to policy makers, managers…
Sponge aggregation factor and sponge hemagglutinin: possible relationships between two different molecules.
1979
Abstract A lectin from the marine sponge GEODIA CYDONIUM was isolated and characterized. GEODIA lectin (GL) agglutinates human red blood cells irrespective of the ABO blood group and precipitates with a variety of D -galactose containing glycosubstances, i.e. certain snail galactans, bovine erythrocyte glycoprotein and PNEUMOCOCCUS type XIV polysaccharide. The only simple sugars inhibiting the GL-mediated hemagglutination were lactose and n -acetyl- D -galactosamine. GL was purified by affinity chromatography on Sepharose 4B almost to homogeneity as tested by polyacrylamide disc gel electrophoresis. Positive staining of the lectin band with Coomassie brilliant blue and PAS suggest that GL i…
Improved Photocatalytic Activity of Polysiloxane TiO2 Composites by Thermally Induced Nanoparticle Bulk Clustering and Dye Adsorption
2021
Fine control of nanoparticle clustering within polymeric matrices can be tuned to enhance the physicochemical properties of the resulting composites, which are governed by the interplay of nanoparticle surface segregation and bulk clustering. To this aim, out-of-equilibrium strategies can be leveraged to program the multiscale organization of such systems. Here, we present experimental results indicating that bulk assembly of highly photoactive clusters of titanium dioxide nanoparticles within an in situ synthesized polysiloxane matrix can be thermally tuned. Remarkably, the controlled nanoparticle clustering results in improved degradation photocatalytic performances of the material under …
Insights on the Mechanism of Insoluble-to-Soluble Prussian Blue Transformation
2009
The electrochemical transformation of the soluble form of Prussian blue (PB) material from the insoluble form was monitored using electrochemical, gravimetric, acoustic, and spectroscopic techniques simultaneously. The described combination of in situ techniques represents an innovative tool for measurement in electrochemistry, which provides complementary information on the electrochemical systems. The insoluble-to-soluble PB transformation process takes place during the successive voltammetric cycles between the mixed valence form (PB) and the fully reduced form [Everitt's salt (ES)]. One of the processes that takes place is the exit of free Fe(CN) 4- 6 ions occluded in the vacancies of t…
Infracyanine Green vs. Brilliant Blue G in Inverted Flap Surgery for Large Macular Holes: A Long-Term Swept-Source OCT Analysis
2020
Background and Objectives: To compare the long-term toxicity of infracyanine green (IFCG) to brilliant blue G (BBG) in inverted internal limiting membrane flap surgery (I-ILMFS) for large, full-thickness macular holes (FTMHs). Materials and Methods: Prospective randomized study including 39 eyes with &ge
Roquefortine C occurrence in blue cheese.
2001
Several strains of Penicillium are used for the production of mold-ripened cheeses, and some of them are able to produce mycotoxins. The aims of the research were the determination of roquefortine C and PR toxin in domestic and imported blue cheeses, the identification of the penicillia used as starter, and the investigation of their capacity for producing toxins in culture media. Roquefortine C was always found in the cheeses at levels ranging from 0.05 to 1.47 mg/kg, whereas the PR toxin was never found. The identification of the fungal strains present in the domestic cheeses included Penicillium glabrum, Penicillium roqueforti, and Penicillium cyclopium in the Gorgonzola "dolce" and Peni…
Managing a Pan-European Consortium on Late Effects among Long-Term Survivors of Childhood and Adolescent Cancer—The PanCareLIFE Project
2021
PanCareLIFE brought together European partners and is the largest study to have evaluated the issues of fertility impairment, hearing loss, and health-related quality of life in survivors of childhood and adolescent cancer. Successful delivery of the project aims did not evolve solely from scientific qualities. Organizational structure and careful information management were key components for its successful completion and are retrospectively assessed in this paper. PanCareLIFE used cohort studies, case-control studies, clinical evaluation of hearing, and genetic testing to study 32,000 survivors from 25 data providers. A management team implemented the organizational structures, was the de…
Luminescent PhotoCORMs: Enabling/Disabling CO Delivery upon Blue Light Irradiation.
2020
The new luminescent carbonyl compounds [Mn(Oxa-H)(CO)3Br] (1) and [Mn(Oxa-NMe2)(CO)3Br] (2) were synthesized and fully characterized. Complexes 1 and 2 showed CO release under blue light (λ453). Spectroscopic techniques and TD-DFT and SOC-TD-DFT calculations indicated that 1 and 2 release the Oxa-H and Oxa-NMe2 coligands in addition to the carbonyl ligands, increasing the luminescence during photoinduction.
