Law and glocalization
2022
The chapter intends to analyze the existing relationship between, law, globalization and grobalization. Having briefly illustrated the key concepts of globalization and grobalization, in order to examine the above relationship the chapter analyzes first the concepts of hybridity, mixity and diffusion as used in comparative law, in order to determine to which extent the same concepts as used in legal sociology cannot create misunderstandings. After having clarified all the key elements for the analysis, then the chapter focuses on how globalization and grobalization intersect with law, putting forward some related examples. The chapter ends with some conclusive remarks.
In vitro evaluation of the antibacterial activity of cured dentin/enamel adhesive incorporating the antimicrobial agent MDPB
2010
The aim of this study was to investigate in vitro the antibacterial effect of a dentin/enamel adhesive containing MDPB (Clearfil Protect Bond) after curing and to compare it with an adhesive not containing MDPB (Clearfil SE Bond). The antibacterial effect of the cured adhesives was tested on Enterococcus faecalis by the evaluation of growth inhibition in a 48-h microplate direct contact test (DCT). The presence of antibacterial activity due to soluble components was also investigated by an agar diffusion test (ADT) performed with the adhesives cured on the surface of dentin disks. In the DCT, both the tested materials showed complete inhibition of bacterial growth until the 7-h reading, reg…
Studio di parcellizzazione talamica per l’identificazione del target di trattamento applicato alle talamotomie trans-craniche mediante ultrasuoni foc…
2019
SCOPO DEL LAVORO: La tcMRgFUS consente di effettuare una vera e propria esplorazione neurofunzionale per confermare ed ottimizzare il target lesionale prima di indurre una lesione cerebrale permanente. La scelta del target di trattamento si basa tuttavia su coordinate stereotassiche che non tengono conto delle diversità anatomiche di ciascun individuo. Essendo il paziente vigile durante tutta la durata della procedura, l'ottimizzazione del target di trattamento viene effettuata sulla base del feedback del paziente nel corso della procedura utilizzando sonicazioni di potenza sub-lesionale. Scopo di questo lavoro è valutare retrospettivamente il possibile ruolo della parcellizzazione talamica…

Introduzione La tcMRgFUS consente di effettuare una vera e propria esplorazione neurofunzionale per confermare ed ottimizzare il target lesionale prima di indurre una lesione cerebrale permanete. La scelta del target di trattamento si basa tuttavia su coordinate stereotassiche che non tengono conto delle diversità anatomiche di ciascun individuo. L'ottimizzazione del target di trattamento viene effettuata sulla base del feedback del paziente durante la procedura stessa. Materiali e metodi È’ stato utilizzato uno scanner RM da 1.5T per acquisire sequenze morfologiche 3D e ultrastrutturali (DTI) in pazienti successivamente sottoposti a tcMRgFUS. È stata effettuata una segmentazione delle aree…
Thalamic parcellation for target identification in trans-cranial MR-guided Focused UltraSound (tcMRgFUS) thalamotomies: a preliminary probabilistc tr…
2018
Background: Trans-cranial MR-guided Focused UltraSound (tcMRgFUS) allows a neurofunctional exploration of thalamic nuclei to confirm and optimize the target before inducing a permanent brain lesion. However, the choice of the target is based on stereotactic coordinates that do not take into account the anatomical variability of each single patient. Thus, the optimization of the treatment target is based on the patient's feedback during lower power sonications. The aim of this work is to retrospectively evaluate the possible role of thalamic parcellation for the identification of the intermediate ventral nucleus (VIM) in patients undergoing tcMRgFUS. Materials and Methods: A 1.5T MR scanner …
Low-cost high-haze films based on ZnO nanorods for light scattering in thin c-Si solar cells
2015
Light scattering from ZnO nanorods (NR) is investigated, modeled, and applied to a solar cell. ZnO NR (120-1300 nm long, 280-60 nm large), grown by low-cost chemical bath deposition at 90 degrees C, exhibit diffused-to-total transmitted light as high as 70% and 30% in the 400 and 1000 nm wavelength range, respectively. Data and scattering simulation show that ZnO NR length plays a crucial role in light diffusion effect. A transparent ZnO NR film grown on glass and placed on top of a 1 mu m thick c-Si solar cell is shown to enhance the light-current conversion efficiency for wavelengths longer than 600 nm.

What happened to body-to-body sociability?
2013
This article aims to investigate how the body-to-body forms of sociability evolved from 1996 to 2009 simultaneously with the proliferation of ICTs in Europe and why this happened. The article also aims to find out how the socio-demographic profile of Europeans practising these forms developed in the same period of time. The analysis is based on two surveys carried out in Italy, France, the United Kingdom, Germany and Spain in 1996 (N = 6609) and 2009 (N = 7255). Results show that although the internal diffusion and frequency of the forms of communicative sociability changed, on the whole the amount of sociability has increased so slightly that it would be more appropriate to speak about rea…
Die thermische diffusion von polystyrol in verschiedenen lösungsmitteln
1969
Es wird uber Messungen von thermischen Diffusionskoeffizienten und LUDWIG-SORET-Koeffizienten von Polystyrol in den Losungsmitteln Toluol, Methylathylketon, Butylacetat und Cyclohexan berichtet. Es zeigte sich, das der rein thermisch bedingte Diffusionsprozes in Butylacetat und im Θ-Losungsmittel Cyclohexan unabhangig vom Molekulargewicht ist, wie as fur Toluol bereits fruher nachgewiesen werden konnte. Fur Methylathylketon wurde eine schwache, aber deutliche Abhangigkeit von D' vom Molekulargewicht zu D' ∼ M−0,12 gefunden. Bemerkenswerterweise verhalten sich die beiden in Bezug auf Polystyrol thermodynamisch sehr ahnlichen Losungsmittel Butylacetat und Methylathylketon in dieser Hinsicht s…
Le processus de diffusion du football en Franche-Comté
2006
This paper seeks to demonstrate, from a geographical viewpoint, how football, a sport that was fairly undeveloped at the beginning of the 20th century, has become a major element in daily life. Taking the region of Franche-Comté (population: 1.1 million) as an example, the spatialisation of the diffusion cycle of the sport is shown (introduction into the territory, growth, then saturation). The territorial dimension of football is thus analysed.
Self-organization and nanostructural control in thin film heterojunctions.
2013
In spite of more than two-decades of studies of molecular self-assembly, the achievement of low cost, easy-to-implement and multi-parameter bottom-up approaches to address the supramolecular morphology in three-dimensional (3D) systems is still missing. In the particular case of molecular thin films, the 3D nanoscale morphology and function are crucial for both fundamental and applied research. Here we show how it is possible to tune the 3D film structure (domain size, branching, etc.) of thin film heterojunctions with nanoscale accuracy together with the modulation of their optoelectronic properties by employing an easy two-step approach. At first we prepared multi-planar heterojunctions w…
