La 'cestinazione' delle pseudonotizie di reato. Ristampa emendata e aggiornata
2010
Il lavoro intende prospettare un’esposizione sintetica e nel contempo completa che introduca le più importanti questioni interpretative sottese solitamente a quelle ‘prassi devianti’, troppo spesso presenti nelle dinamiche processuali, che mettono in luce proprio i limiti connaturali all’attuale assetto dei doveri e dei poteri del pubblico ministero. Restare inerti davanti alla loro crescente diffusione senza riflettere sui possibili rimedi, rintracciabili anche nei labirinti del processo, rischia di condurre allo svuotamento di principi costituzionali, tra cui quello dell’obbligatorietà dell’azione penale, che vanno difesi in vista di preavvertiti indizi che vorrebbero vederli fortemente a…
Efficacy of the antioxidant ebselen in experimental uveitis.
1999
Inflammation results in the production of free radicals. In a model of experimental uveitis upon subcutaneous injection of endotoxin to Lewis rats, i.e., endotoxin-induced experimental uveitis (EIU), we have evaluated the status of the antioxidant capacity of ocular tissues. EIU results in a decrease of glutathione (GSH) content and glutathione peroxidase (GPx) activity in whole eye homogenates 24-h after endotoxin administration. Furthermore, an increase in malondialdehyde (MDA) content was observed in these same samples, thus confirming the involvement of oxidative stress in the pathophysiology of the process. In view of the ability of the antioxidant ebselen as GPx enzyme mimic, we teste…
Disentangling the rhizosphere effect on nitrate reducers and denitrifiers: insight into the role of root exudates.
2008
International audience; To determine to which extent root-derived carbon contributes to the effects of plants on nitrate reducers and denitrifiers, four solutions containing different proportions of sugar, organic acids and amino acids mimicking maize root exudates were added daily to soil microcosms at a concentration of 150 μg C g−1 of soil. Water-amended soils were used as controls. After 1 month, the size and structure of the nitrate reducer and denitrifier communities were analysed using the narG and napA, and the nirK, nirS and nosZ genes as molecular markers respectively. Addition of artificial root exudates (ARE) did not strongly affect the structure or the density of nitrate reduce…
In light of the ends. Copyright hysteresis and private copy exception after the British Academy of Songwriters, Composers and Authors (BASCA) and oth…
2015
In British Academy of Songwriters, Composers and Authors (BASCA) and others v Secretary of State for Business, Innovation and Skills, the High Court of Justice in matter of private copy exception provides the twofold prime opportunity to shed light on the state of the art of copyright in the UK and to flesh out the idea of 'legal hysteresis’. I support the reintroduction of the private copy exception, possibly in a less narrow fashion, and I explain the reasons why I am confident that my expectations will be fulfilled.
Visible and near-infrared multispectral analysis of geochemically measured rock fragments at the Opportunity landing site in Meridiani Planum
2010
[1] We have used visible and near-infrared Panoramic Camera (Pancam) spectral data acquired by the Opportunity rover to analyze 15 rock fragments at the Meridiani Planum landing site. These spectral results were then compared to geochemistry measurements made by the in situ instruments Mossbauer (MB) and Alpha Particle X-ray Spectrometer (APXS) to determine the feasibility of mineralogic characterization from Pancam data. Our results suggest that dust and alteration rinds coat many rock fragments, which limits our ability to adequately measure the mineralogy of some rocks from Pancam spectra relative to the different field of view and penetration depths of MB and APXS. Viewing and lighting …
Low-pressure fractionation of the Nyiragongo volcanic rocks, Virunga Province, D.R. Congo
2004
Abstract A new petrogenetic model for the Nyiragongo volcanics based on petrological and geochemical studies of a wide range of highly alkaline and silica-undersaturated fractionated rocks (Mg# 23–44) invokes low-pressure fractionation occurring mainly within the Nyiragongo volcanic edifice. The most primitive Nyiragongo rocks seem correspond to a pyroxene-nephelinitic melt which evolved to melilite nephelinite and melilitite by fractionation of leucite, together with varying amounts of nepheline. Leucite nephelinite, leucitite and leucite tephrite represent rock types originating partly by phenocryst accumulation. Mineral and bulk rock geochemistry of pyroxene nephelinites indicate an alre…
Fabric control on strain and rupture of heterogeneous shale samples by using a non-conventional mechanical test
2004
Abstract This work was a part of the preliminary stage of the ANDRA project on a deep-seated research laboratory for the feasibility study of long-term radioactive waste storage in the Callovo–Oxfordian argillites of the Eastern part of the Paris Basin. These rocks are bedded, their density is about 2.4, and they contain an average of 30% carbonates and 25% quartz. Thick (5 mm) sections from cores were put through a non-conventional device called CGI testcell (CGI: Centre de Geologie de l'Ingenieur, i.e. Engineering Geology Centre). The aim of this versatile device is to achieve plane deformation tests under compressive uniaxial loading together with controlled temperature and humidity cond…
Water transmission properties of a sandy-loam soil estimated with Beerkan runs differing by the infiltration time criterion
2021
Abstract The Beerkan method consists of a ponded infiltration experiment from a single ring inserted a small depth into the soil. Fixed, small volumes of water are repeatedly poured into the ring to maintain a quasi-zero head on the soil surface. According to the standard Beerkan infiltration run, a new water volume is poured on the infiltration surface when the previously applied volume has completely infiltrated and the soil surface is entirely exposed to air (ta criterion). However, water could also be applied when the soil exposition to air begins (to criterion) or half the soil surface is exposed to air (tm criterion). The effect of the infiltration time criterion on determination of t…
Le ferite sociali prodotte dalla criminalità organizzata, come categoria interpretativa del cambiamento
2018
Il presente contributo vuol essere una cornice epistemologica degli interventi seguenti, proponendo una riflessione di carattere sociologico sulle “ferite sociali” derivanti dalla violenza delle azioni della criminalità organizzata nel tessuto sociale e sulle conseguenze che queste ferite innescano a livello collettivo. Di fronte al dolore e alla sofferenza, la società civile riesce ad attivare meccanismi di resilienza che danno impulso a capacità pro-attive, che diventano strumenti di trasformazione positiva di dinamiche distorte come quelle messe in atto dalla criminalità organizzata e di dinamiche negative che hanno afflitto e affliggono la società in precisi momenti e contesti storici.
Particles of vaterite, a metastable CaCO3polymorph, exhibit high biocompatibility for human osteoblasts and endothelial cells and may serve as a biom…
2018
We have previously described a promising alternative to conventional synthetic bone biomaterials using vaterite, a metastable CaCO3 polymorph that increases the local Ca2+ concentration in vitro and leads to an oversaturation of phosphate, the primary bone mineral. This stimulates a natural bone-like mineralisation in a short period of time. In this study, sterile and endotoxin-free vaterite particles were synthesised in a nearly quantitative yield. The 500-1,000 nm vaterite particles did not exhibit any cytotoxic effects as measured by MTS, lactate dehydrogenase, or crystal violet assays on the human osteoblast cell line (MG-63) exposed to concentrations up to 500 μg/ml vaterite up to 72 h…
