Le législateur n’a pas défini immédiatement la notion de récidive. En effet, les articles 54 à 57 du Code pénal se limitent à énumérer les diverses hypothèses qui peuvent ou doivent entraîner une augmentation de la peine qui sera prononcée par le juge à l’encontre du prévenu ou de l’accusé. Aussi, nous pouvons dire que la récidive s’entend comme le fait du délinquant qui, ayant déjà été condamné pénalement en vertu d’une décision judiciaire devenue définitive, est traduit, à nouveau, devant un tribunal pour répondre d’une infraction. Le texte examine les conséquences de la récidive sur la situation du prévenu. [less ▲]

Changes in conscious level have been associated with changes in dynamical integration and segregation among distributed brain regions. Recent theoretical developments emphasize changes in directed functional (i.e., causal) connectivity as reflected in quantities such as 'integrated information' and 'causal density'. Here we develop and illustrate a rigorous methodology for assessing causal connectivity from electroencephalographic (EEG) signals using Granger causality (GC). Our method addresses the challenges of non-stationarity and bias by dividing data into short segments and applying permutation analysis. We apply the method to EEG data obtained from subjects undergoing propofol-induced anaesthesia, with signals source-localized to the anterior and posterior cingulate cortices. We found significant increases in bidirectional GC in most subjects during loss-of-consciousness, especially in the beta and gamma frequency ranges. Corroborating a previous analysis we also found increases in synchrony in these ranges; importantly, the Granger causality analysis showed higher inter-subject consistency than the synchrony analysis. Finally, we validate our method using simulated data generated from a model for which GC values can be analytically derived. In summary, our findings advance the methodology of Granger causality analysis of EEG data and carry implications for integrated information and causal density theories of consciousness. [less ▲]

We report an experimental study of a binary sand bed under an oscillating water flow. The formation and evolution of ripples is observed. The appearance of a granular segregation is shown to strongly depend on the sand bed preparation. The initial wavelength of the mixture is measured. In the final steady state, a segregation in volume is observed instead of a segregation at the surface as reported before. The correlation between this phenomenon and the fluid flow is emphasised. Finally, different "exotic" patterns and their geophysical implications are presented. [less ▲]

An experimental study of a granular surface submitted to a circular fluid motion is presented. The appearance of an instability along the sand-water interface is observed beyond a critical radius r(c). This creates ripples with a spiral shape on the granular surface. A phase diagram of such patterns is constructed and discussed as a function of the rotation speed omega of the flow and as a function of the height of water h above the surface. The study of r(c) as a function of h, omega, and r parameters is reported. Thereafter, r(c) is shown to depend on the rotation speed according to a power law. The ripple wavelength is found to decrease when the rotation speed increases and is proportional to the radial distance r. The azimuthal angle epsilon of the spiral arms is studied. It is found that epsilon scales with homegar. This lead to the conclusion that epsilon depends on the fluid momentum. Comparison with experiments performed with fluids allows us to state that the spiral patterns are not the signature of an instability of the boundary layer. [less ▲]

During 47 days, 80 weaned pigs, allotted to 2 groups of 30 and 50 animals, were given choice simultaneously between pellets or meal distributed ad libitum in feeders equipped with an integrated watering system. The average daily weight gain was 0.4250.058 kg, without significant difference between groups, and the mean feed conversion ratio was 1.72. The mean feed intake with pellets was double that with meal (0.49 vs. 0.24 kg/head daily). However, the pellet feeders and meal feeders were occupied for the same proportion of time: the mean occupation times were 45.5 and 42.8% (30 pigs) and 62.4 and 67.3% (50 pigs), respectively. Eating pellets seems thus to take less time than eating meal. Furthermore, we have observed that animals from the larger group were eating more quickly than members of the smaller one. Even if the feed intake of pigs with pellets was twice that with meal, pigs drank more water (60% of the total water intake) using the meal feeder. Thus, with pellets, pigs don't seem to choose a close association between feed and water consumption. In conclusion, pigs prefer pellets to meal, this choice being probably partially explained by a faster ingestion. This eating speed depending also on the group size, the number of eating places should thus take into account these two parameters. [less ▲]

Background. Several chemoattractants have been measured in exhaled breath condensate (EBC) from patients with COPD. The aim of this study was to compare the eosinophil. and neutrophil chemotactic activity contained in EBC from healthy subjects and patients with COPD. Methods: EBC collected using a commercially available condenser (EcoScreen; Erich Jaeger Viasys; Hoechberg, Germany) was compared in 45 COPD patients and 65 healthy subjects. EBC chemotactic activity for eosinophils and neutrophils was assessed using microchambers (Boyden; Neuro Probe; Cabin John, MD). Chemotactic index (CI) was used to evaluate cell migration. Results: EBC from patients with COPD (C1, 2.21 +/- 0.16 [mean +/- SEM]) and healthy subjects (CI, 1.67 +/- 0.11) displayed significant neutrophil chemotactic activity (p < 0.0001 for both), which was however higher in patients with COPD (p < 0.001). Healthy smokers had a significantly raised C1 for neutrophils by comparison with healthy nonsmokers (p < 0.01) and ex-smokers (p < 0.05). Ukewise, current COPD smokers tended to have greater neutrophil C1 than COPD who stopped smoking (p = 0.08). COPD ex-smokers had raised chemotactic activity by comparison with healthy ex-smokers (p < 0.05). Anti-interleuldn-8 (10(-6) g/mL) antibodies reduced neutrophil chemotactic activity by 35.2% (p < 0.05). EBC also contained significant eosinophil chemotactic activity in healthy subjects (CI, 1.68 0.09; p < 0.0001) and patients with COPD (CI, 1.23 +/- 0.07; p < 0.01), with a significantly lower CI in patients with COPD as compared to healthy subjects (p < 0.001). Smoking did not influence eosinophil chemotactic activity in healthy subjects or patients with COPD. Conclusions: Current smoking favors neutrophil chemotactic activity. As compared to healthy subjects, EBC from patients with COPD displays a skewed chemotactic activity toward neutrophils vs eosinophils. [less ▲]
