La Corte eur. dir. uomo e la non discriminazione tra coppie etero e omoaffettive
2018
Il saggio analizza le ricadute sul dibattito in tema di diritti fondamentali della recente decisione della Corte di Strasburgo su un singolare caso di discriminazione in base all’orientamento sessuale per così dire "alla rovescia" , in quanto dovuta all’inaccessibilità alla coppie eterosessuali austriache all’istituto della Partnership registrata, riservato alle coppie same-sex. Esaminata la giurisprudenza della Corte europea dei diritti dell'uomo in tema di non discriminazione in base all'orientamento sessuale e la soluzione adottata nel caso in questione con l'attestarsi della maggioranza dei giudici sulla dottrina del “separate but equal”, l'indagine si volge poi a considerare le spinte …
Flow cytometric analysis of chronic and acute toxicity of copper(II) on the marine dinoflagellateAmphidinium carterae
2001
Background Copper(II) is a heavy metal whose levels have increased in some marine ecosystems to polluting levels. Dinoflagellates, an important phytoplankton group, are at the base of aquatic food chains and bioaccumulation of copper by these microorganisms can result in complex ecosystem alterations, so we investigated how copper disturbs those cells. Methods Cytotoxic effects of sublethal and lethal copper concentrations ranging from 4.2 nM (control condition) to 3.13 μM estimated labile copper were studied in batch cultures of Amphidinium carterae. Cell morphology, motility, autofluorescence, and fluorescein diacetate (FDA)–dependent fluorescence generation were evaluated by flow cytomet…
Dating archaeological copper/bronze artifacts by using the voltammetry of microparticles.
2014
A method for dating copper/bronze archaeological objects aged in atmospheric environments is proposed based on the specific signals for cuprite and tenorite corrosion products measured through the voltammtry of microparticles method. The tenorite/cuprite ratio increased with the corrosion time and fitted to a potential law that yielded a calibration curve usable for dating purposes.
Socio-technical risk governance through dyadic risk dialogue : copper corrosion as a safety challenge in the geological disposal of spent nuclear fuel
2014
The risk of corrosion in oxygen-free water has become an issue of scientific controversy possibly even threatening the realisation of the final disposal of spent nuclear fuel in Finland and Sweden. In Sweden there has been extensive discussion about the issue since 2007, but only recently has this debate increased in Finland although the similar disposal concept (KBS-3) is applied in both countries. In this report, we analyse how the implementer, Posiva (a Finnish nuclear waste company), and the regulator, STUK (the Finnish Radiation and Nuclear Safety Authority), have been engaged in a dialogue on the risk of copper corrosion. For over thirty years the implementer and regulator have been e…
Cadmium Metal–Organic Frameworks Based on Ditopic Triazamacrocyclic Linkers: Unusual Structural Features and Selective CO 2 Capture
2017
International audience; Two three-dimensional cadmium metal organic frameworks with general formula [Cd-2(L-1)(H2O)(3)](NO3)(0.7)(HCOO)(0.2)Br-0.1 (Cd2L1, L-1 = 1,4,7-tris(4-carboxybenzy1)-1,4,7-triazacyclononane) and Cd(HL2)(H2O)(2) (CdL2, L-2 = 1,4,7-tris(3-(4-benzoate)prop-2-yn-1-yl)-1,4,7-triazacydononane) based on 1,4,7-triazacyclononane N-functionalized by different arylcarboxylic acids were prepared under solvothermal conditions and characterized by single crystal X-ray analysis and porosity measurements. The crystal structure of Cd2L1 reveals a cationic net with a bcs topology,. and nodes are constituted by dinuclear cadmium complexes, in which each cadmium atom adopts a hexacoordin…
