I corpi del virus
2020
In un articolo recentemente uscito in italiano, Bruno Latour spiega che il nuovo coronavirus illustra in modo eclatante come gli attori non umani irrompano nei nostri spazi collettivi esigendo profonde trasformazioni (e invitando a ripensare così noi stessi al loro interno). Al momento è impossibile valutare questi cambiamenti sul lungo periodo. È chiaro però che SARS-CoV-2 ha avuto subito effetti visibilissimi sulle istituzioni che danno forma al nostro universo collettivo: mercati finanziari, filiere produttive, sistemi sanitari, regolamenti, lockdown. Mi sembra che il luogo di convergenza di questi ambiti tematici sia il corpo, figura in cui si incrociano le isotopie mediche, economiche,…

Corpo e movimento come arte della costruzione di Sé: Danza Movimento Terapia e formazione
2016
In this paper I present a training model for educators based on a DMT course at the University and I will explain the theoretical and methodological framework related to the educational goals. The aim is to give professional skills to be spent in educational and social fields thanks to the mobilization of creativity , the integration between the different parts of Self and the development of awareness and the "presence". At the same time, students, through the artistic experience centered on the body, enhance the competences (observational, communicative, interpersonal, etc) required for their job in the future . A DMT course activates, indeed, new stories and new existential perspectives i…
Characterization of spatial porosity and mineral distribution of crystalline rock using X-ray micro computed tomography, C-14-PMMA autoradiography an…
2019
The spatial porosity and mineral distribution of geological materials strongly affects transport processes in them. X-ray micro computed tomography (X-mu CT) has proven to be a powerful tool for characterizing the spatial mineral distribution of geological samples in 3-D. However, limitations in resolution prevent an accurate characterization of pore space especially for tight crystalline rock samples and 2-D methods such as C-14-polymethylmethacrylate (C-14-PMMA) autoradiography and scanning electron microscopy (SEM) are needed. The spatial porosity and mineral distributions of tight crystalline rock samples from Aspo, Sweden, and Olkiluoto, Finland, were studied here. The X-mu CT were use…
Approximation of pore space with ellipsoids: a comparison of a geometrical method with a statistical one.
2018
International audience; We work with tomographic images of pore space in soil. The images have large dimensions and so in order to speed-up biological simulations (as drainage or diffusion process in soil), we want to describe the pore space with a number of geometrical primitives significantly smaller than the number of voxels in pore space. In this paper, we use the curve skeleton of a volume to segment it into some regions. We describe the method to compute the curve skeleton and to segment it with a simple segment approximation. We approximate each obtained region with an ellipsoid. The set of final ellipsoids represents the geometry of pore space and will be used in future simulations.…
Created substrates do not fully mimic natural substrates in restoration: the occurrence of polypores on spruce logs
2014
Many protected areas have been under intensive forest management prior to protection and thus lack natural ecosystem structures and dynamics. Dead wood is a key structure in forests harboring hundreds of threatened species. We investigated the ecological success of dead wood creation as a boreal forest restoration measure. We analysed whether the polypore communities of chain-saw felled and girdled (subsequently fallen) Norway spruce ( (L.) H. Karst.) logs differ from naturally formed spruce logs of similar decay stage and size. The study was conducted in Leivonmäki National Park in central Finland 8 years after the restoration measures. The average number of polypore species was highest o…

The occurrence of Echinorhynchus salmonis Müller, 1784 in benthic amphipods in the Baltic Sea
2015
The acanthocephalan Echinorhynchus salmonis Muller, 1784 is a common parasite of salmonid fish, but it has rarely been reported from an intermediate host. Samples of benthic amphipods, Monoporeia affinis (Lindstrom), were taken from multiple, deep sites (usually below 70 m) in the Gulf of Bothnia over the course of more than a decade and examined for acanthocephalans. Overall, only 0.44% of 23 296 amphipods were infected, all with just a single worm. This prevalence is consistent with several previous reports of acanthocephalans in deep-water, benthic amphipods, but it appears low compared to that often reported for acanthocephalan species infecting littoral amphipods. Parasite occurrence d…
The Origin of Non-thermal Fluctuations in Multiphase Flow in Porous Media
2021
Core flooding experiments to determine multiphase flow in properties of rock such as relative permeability can show significant fluctuations in terms of pressure, saturation, and electrical conductivity. That is typically not considered in the Darcy scale interpretation but treated as noise. However, in recent years, flow regimes that exhibit spatio-temporal variations in pore scale occupancy related to fluid phase pressure changes have been identified. They are associated with topological changes in the fluid configurations caused by pore-scale instabilities such as snap-off. The common understanding of Darcy-scale flow regimes is that pore-scale phenomena and their signature should have a…
