Supercritical CO2 and N2O pasteurization of fresh peach and kiwi juice
No full textThe microbial inactivation and qualitative parameters (pH, sugar content, titratable acidity, absorbance at 420 nm and turbidity) of peach and kiwi juices treated at 35 °C with supercritical carbon dioxide (SC-CO2) and nitrous oxide (SC-N2O) were determined as a function of pressure and treatment time. Total inactivation of both naturally occurring microorganisms and Saccharomyces cerevisiae strain (105 cfu mL-1) was obtained after 15 min of SC-CO2/N2O treatment, 10 MPa and 35 °C, for both juices. No significant changes in chemical-physical or in sensorial characteristics between untreated and treated juice were detected. The results obtained demonstrate the feasibility and the potential of SC-CO2/N2O treatment as an alternative low temperature pasteurisation process for peach and kiwi juices. © 2010 The Authors.

Fishing Grounds Detection by Satellite Remote Sensing Techniques
No full textQuick detection of fishing grounds using satellite based remote sensing techniques can significantly reduce the searching time, the usage of fuel and the human effort and increase the CPUE (Catch per unit effort). Multi-temporal and multi-sensor data fusion techniques have been applied to MODIS-AQUA, MODIS-TERRA and VIIRS multi-spectral data to detect chlorophyll and temperature fronts in the low Adriatic and in the Ionian seas. These fronts are generated by the upwelling of cold waters rich of phytoplankton nutrients where an high concentration of pelagic fish is expected. CPUE data have been provided by the FEDERPESCA fleet relative to the 2013 and 2014 fishing campaigns conducted in the areas of interest. An automatic procedure has been developed to calibrate and validate the production in near-real time of daily maps of expected good fishing grounds to be provided to the FEDERPESCA fleet. The same procedure could be optimized also for other seas
Performance of comprehensive complication index and clavien‐dindo complication scoring system in liver surgery for hepatocellular carcinoma
No full textMarsilius of Inghen on incipit and desinit in Consequentiae ii, Chapters 4-5
No full textIn this paper, the author offers an introduction to Marsilius of Inghen’s treatment of expositiones of sentences de incipit and de desinit in his treatise on Consequentiae, with an analysis of the various modi exponendi presented by Marsilius and an edition of the text. The author argues that, in the split between physical and logical approaches to the issues arising in analyses of incipit and desinit, Marsilius’ theory presents some hybrid features, but tends towards the logical end of the spectrum.</jats:p
Crisisification et la Boussole Strategique: redéfinition l'(auto)représentation du rôle de l'UE sur la scène internationale ?
No full textInternational audienceTo improve its capacity building, cohesion and effectiveness in the international arena, the EU would like to strengthen the capacity for crisis prevention, intervention and management, through the Strategic Compass. A decision-making method oriented, above all, to crisis response and prevention is already present alongside “traditional” EU decision-making method – i.e., based on long consultations with stakeholders, a long process of mediation and balance between positions to achieve solutions based on consensus and long-term policies. This phenomenon – this change in the nature of the processes by which collective decisions are made – is called crisisification by Mark Rhinard: it consists in ‘finding the next urgent event, prioritizing speed in decision-making, ushering in new constellations of concerned actors and emphasizing new narratives of what matters in European governance’ (Rhinard 2019). According to the discourse of the EU institutions (EEAS 2021), past and, above all, future crises play an essential role in the construction of the Strategic Compass and the “next CSDP”: this could mean that crisisificaiton could, potentially, “prevail” on the traditional method of decision-making, reshaping the (self)representation of the EU role as foreign policy actor and the political processes (internal and external, formal and informal) of CSDP. To do this, the CSDP political discourse arising from the last three decades of political debate – e.g., EU as "civilian power" (Telò 2006), "slow power" etc. – must be first "reform" through a reframing operation which has already begun with the publication of the European Union Global Strategy in 2016 (EUGS) but which could “change gear” with the adoption and publication of the Strategic Compass. More in detail, framing consists of ‘promot[ing] a particular problem definition, causal interpretation, moral evaluation and/or treatment recommendation. [...] Frames diagnose, evaluate and prescribe’ (Entman 1993). Through the comparative analysis of the CSDP documents and official speeches (starting from the EUGS up to the Strategic Compass), this communication questions the main reframing elements of the CSDP discourse arising from the Strategic Compass, how these could impact the self-representation of European actors (governments and institutions) in the international arena and how (and how much) these changes could potentially lead to a crisisification of the CSDP – with important consequences on the identity of European foreign policy and the resulting political processes

CAR-SLIDE project: integration of EO technologies and diagnostic systems for advanced transport infrastructure monitoring
No full textCAR-SLIDE is a MIUR project (PON RandC 2007-2013) aimed to implement an advanced diagnostic system capable to monitor landslide and flood events along the national rail networks, by integrating in situ data detected from on board sophisticated innovative measuring systems, with Earth Observation techniques (based on weather forecast, SAR and optical data). In order to highlight the potential of COSMO/SkyMed satellite data for geohazard detection and mapping, two test cases are presented in this work. The first one consists in the application of multitemporal SAR/InSAR techniques for monitoring recent flood events in the Basilicata region, causing rail service interruptions. The second example consists in a retrospective analysis on the detection of precursory signals related to the landslide which occurred on January 2014 close to the town of Marina di Andora. The landslide caused the derailment of a train and the interruption of the railway line connecting north-western Italy to France
The acute effects of a stretching and conditioning exercise protocol for the lower limbs on gait performance- a proof of concept and single-blind study
No full textBackground :Due to improvement in movement performance, post-activation performance enhancement (PAPE) may open new possibilities to improve gait performance. However, no study has attempted to translate this phenomenon into walking. Therefore, the study aimed to test whether acute stretching followed by a conditioning exercise can improve subsequent gait performance in healthy adults. Research question Can an exercise protocol subsequently improve gait performance? Methods: Sixteen individuals walked four 10-m trials (in each period) before and after 7 min of an exercise protocol composed of stretching (focusing on the lower limb) and a conditioning exercise (standing calf-raise wearing a vest of 20 kg). Gait spatial temporal parameters and muscle activity of tibialis anterior and gastrocnemius medialis and lateralis muscles were obtained by a 3D-motion system and wireless electromyography, respectively. Before and after the exercise protocol, kinematic and muscle activity parameters were compared by a one-way ANOVA and the Wilcoxon signed-rank test, respectively. Results :After the exercise protocol, the participants walked with a faster step velocity (p < 0.018) and with a lower step duration (p < 0.025). Also, higher peak muscle activity (p < 0.008) and low-frequency (p < 0.034) activation of the anterior tibial muscle after the exercise protocol were observed. Significance: In conclusion, the protocol improves the stability and the muscles' efficiency during gait, contributing to a new approach to enhancing gait rehabilitation programsFunding
