L'objectif de ma contribution est de mettre en lumière le processus de construction de la figure du sorcier, qui répond à une double logique d'accumulations et d'exagérations des accusations. Ces dernières renvoient à quatre registres principaux, à commencer par celui de la diabolisation des pratiques de magie et de sorcellerie. Par ailleurs, le sabbat des sorcières est perçu comme une anti-église démoniaque qui réunit une secte éminemment dangereuse d'hérétiques et d'apostats qui ont conclu un pacte avec le diable. Le fantasme du complot ou de la rébellion contribue alors à construire la peur des sectes de sorciers. Enfin, le registre de la contre-nature, tels les crimes immoraux ou tabous associés aux méfaits des sorciers (comportements sexuels déviants, infanticide et cannibalisme d'enfants), favorise quant à lui le dénigrement des individus.

En este artículo presentamos una nueva definición de "útil" para uso interdisciplinar: el útil es aquel objeto, modificado o no y de un material cualquiera, que ayuda o permite a un ser vivo el conseguir una finalidad deseada. Cuatro puntos son desarrollados: 1) el útil no tiene que estar necesariamente modificado, 2) el útil no sólo responde a una materia prima determinada, 3) el empleo de útiles no es exclusivo del hombre y 4) la función del útil varía según la finalidad deseada. Los datos procedentes de la Etnología comparada, la Arqueología experimental, y, sobre todo, de la Etoprimatología nos ayudarán en nuestro objetivo de reconstruir el Pasado, tanto del "útil" como de la conducta instrumental de los primeros homínidos. El estudio de la cultura material del chimpancé será un factor decisivo.

Hematocrit (Hct) is one of the most critical issues associated with the bioanalytical methods used for dried blood spot (DBS) sample analysis. Because Hct determines the viscosity of blood, it may affect the spreading of blood onto the filter paper. Hence, accurate quantitative data can only be obtained if the size of the paper filter extracted contains a fixed blood volume. We describe for the first time a microfluidic-based sampling procedure to enable accurate blood volume collection on commercially available DBS cards. The system allows the collection of a controlled volume of blood (e.g., 5 or 10 μL) within several seconds. Reproducibility of the sampling volume was examined in vivo on capillary blood by quantifying caffeine and paraxanthine on 5 different extracted DBS spots at two different time points and in vitro with a test compound, Mavoglurant, on 10 different spots at two Hct levels. Entire spots were extracted. In addition, the accuracy and precision (n = 3) data for the Mavoglurant quantitation in blood with Hct levels between 26% and 62% were evaluated. The interspot precision data were below 9.0%, which was equivalent to that of a manually spotted volume with a pipet. No Hct effect was observed in the quantitative results obtained for Hct levels from 26% to 62%. These data indicate that our microfluidic-based sampling procedure is accurate and precise and that the analysis of Mavoglurant is not affected by the Hct values. This provides a simple procedure for DBS sampling with a fixed volume of capillary blood, which could eliminate the recurrent Hct issue linked to DBS sample analysis.

The objective of this work was to develop a low-cost portable damage detection tool to assess and predict damage areas in highway bridges. The proposed tool was based on standard vibration-based damage identification (VBDI) techniques but was extended to a new approach based on operational traffic load. The methodology was tested using numerical simulations, laboratory experiments, and field testing.
