Development of an immunochromatographic assay based on carbon nanoparticles for the determination of the phytoregulator forchlorfenuron
2013
Rapid analytical methods enabling the determination of diverse targets are essential in a number of research areas, from clinical diagnostics to feed and food quality and safety. Herein, the development of a quantitative immunochromatographic assay for the detection of the synthetic phytoregulator forchlorfenuron (CPPU) is described. The competitive lateral flow immunoassay (LFIA) was based on the immobilization onto a nitrocellulose membrane of an ovalbumin-CPPU conjugate (test line) and on the use of an immunodetection ligand consisting of carbon nanoparticles labeled with an anti-CPPU monoclonal antibody through interaction with a secondary antibody. The presence of CPPU in horticultural…
X-ray tomographic method for measuring three-dimensional deformation and water content distribution in swelling clays
2015
A non-invasive method for simultaneous measurement of the 3D displacement field and the water content distribution of a wetted solid material is developed. The method is based on comparison of X-ray tomographic images of a material sample in the reference state and in the wetted and deformed state. The deformation and water content analyses were successfully compared with numerical results for a cylindrical rubber test sample under axial compression, and with gravimetric results from axially wetted and sliced cylindrical bentonite samples, respectively. The methods were applied in a 4D study (three spatial dimensions and time) of wetting and deformation of purified swelling bentonite doped …
A new approach for geological faults detection
2004
This paper will introduce a new approach, mainly based on wavelets transform and mathematical morphology, for the detection of geological faults in satellite and aerial photos. This can be useful for territorial analysis, digital cartography and the use of geographical information systems. The proposed method is fast enough and unsupervised. Different techniques will be compared and some examples on real data will be presented to indicate the applicability of these methods.
Synergistic effect of W incorporation and pulsed current mode on wear and tribocorrosion resistance of coatings grown by plasma electrolytic oxidatio…
2019
Ceramic coatings were grown by plasma electrolytic oxidation on 7075 Al alloy using unipolar and bipolar pulsed current waveforms with 20 and 40% cathodic duty cycles, from a silicate-based bath without and with the addition of Na2WO4. Pancake-like morphology was dominant on the coatings grown by unipolar waveform, while the bipolar waveforms promoted volcano-like morphology, increased the roughness of the coating surface and the formation of more compact layers. The coatings produced using the bipolar waveforms provided higher resistances toward both tribocorrosion and dry sliding conditions, while further improvement was achieved by the presence of tungsten. The coatings produced in tungs…

Le Crowdsourcing : problématisation sensible autour d'une mise en forme du lien communautaire
2014
International audience; Alors que l’utilisation des plateformes sociales (réseaux sociaux, blogs, wikis) est désormais généralisée (du côté des internautes comme des organisations), on observe un investissement et un intérêt croissant pour les plateformes de création collaborative, issues du paradigme de l’open-innovation (H.Chesbrough). On insistera plus exactement sur les dispositifs de crowdsourcing et de co-création en ligne ayant pour point commun la mise en relation de communautés (de professionnels, d’ingénieurs, de designers, d’experts, de fans…) avec les enjeux communicationnels des organisations. La recherche à propos de ces nouveaux espaces de collaboration en ligne a été jusqu’i…

Il percorso (incerto) della c.d. web tax italiana tra modelli internazionali ed eurounitari di tassazione della digital economy
2019
L’articolo analizza gli aspetti essenziali dell’evoluzione delle strategie di tassazione delle imprese della digital economy, tanto a livello internazionale, quanto a livello eurounitario, per concludere, poi, con un’analisi dell’art. 1, commi 35 e segg., della Legge 30 dicembre 2018 n. 145 (legge di bilancio 2019), che ha introdotto, nel nostro sistema una vera e propria imposta sulle imprese che operano nel settore digitale, denominata “imposta sui servizi digitali” (ISD). Si osserva, a riguardo, che nel comparto della digital economy, quanto all’aspetto della tassazione, è possibile individuare tre diversi approcci. Il primo attribuisce particolare rilievo alla c.d. “presenza economica s…
Webquest: la formazione
2008
Il webquest è una modalità di ricerca che consente agli studenti di ricavare informazioni da internet, con un percorso guidato da domande prestabilite dagli insegnanti e partendo da siti già validati dai docenti stessi.
