Different chemical reagents (phosphoric acid, boric acid, ammonium citrate, sodium dihydrogen phosphate, potassium dihydrogen phosphate, disodium hydrogen phosphate and trisodium phosphate) were employed to develop activated carbon cloths (ACC) by chemical activation of a lyocell precursor, in an attempt to explore their effect on main physico-chemical characteristics and electrical behaviour of the resulting ACC. The activating agent markedly influenced yield, elemental composition, and textural properties of the ACC. The ACC obtained with phosphoric and boric acids were essentially microporous, whereas those developed with the other reagents presented mesoporosity development. Phosphoric acid-derived samples showed the highest specific surface area (976 m2/g). The results also highlight the relevance of correcting the external surface adsorption in order to obtain reliable estimates of micropore volume. All the ACC were electrically conductive, their resistivity being also strongly dependent on the nature of the activating agent. The electrical resistivity of the ACC obtained with all the phosphorous compounds was successfully correlated with their C/H ratio and micropore volume [less ▲]

High workability together with a good resistance to segregation is needed for cement based composites, specifically fresh Self-Compacting Mortars (SCM); in this prospect, the amount of coarse materials has to be reduced and replaced by fine material. Several limestone fillers are here compared and analysed. These by-products are issued from different industrial sectors, such as the aggregate and lime production industry (quarrying operations) and the ornamental stones industry (sawing operations). Particular attention has been paid to clay content, as consistency of fresh mortars was varying, while other physical characteristics like granulometry remained the same. Relationship between the physico-chemical properties of the fillers and the properties of fresh and hardened mortars are brought forward. Even if it may affect fresh properties of mortars, results clearly show that clay type and content has minor influence than limestone filler itself. [less ▲]

La littérature concernant la consommation énergétique du broyage dans les industries minières montre que cette problématique a été, et est encore, étudiée par de nombreux auteurs. Différents modèles de broyage sont donc disponibles pour ces industries, en particulier pour le broyage des minerais. Les principaux modèles et certaines de leurs évolutions sont repris dans la présente revue. Le broyage de la biomasse quant à lui a été bien moins étudié. Quelques études ont néanmoins porté sur la mesure des consommations énergétiques engendrées par le broyage de biomasses particulières, dans des systèmes particuliers. Rares sont celles qui prennent en compte suffisamment de paramètres relatifs à la matière entrante et sortante (granulométrie, humidité, origine, etc.) ou les caractéristiques du système de broyage. Pratiquement, aucun modèle de broyage de la biomasse n’a donc été proposé. Concernant le broyage des produits densifiés, aucune donnée ne semble disponible. À la lueur des théories de broyage de l’industrie minière, cette étude propose donc les paramètres à prendre en compte pour une éventuelle modélisation du broyage de la biomasse et des produits densifiés.

In the frame of the present study, the influence of liquid viscosity on liquid holdup distribution in a packed column equipped with the modular catalytic packing Katapak-SP 11 is measured. Water and an aqueous solution of glycerine, the viscosity of which equals 10 cP, are used as feed liquids. The estimation of liquid holdup is of great interest due to its strong influence on pressure drop, on solid wetting and on heat and mass transfer coefficients. The experimental technique used is high energy X-ray tomography, which is a unique technique to visualize the local liquid distribution inside the complex structure of packings and to quantify the liquid holdup at different scales.

Le Burkina Faso, s’est engagé depuis plusieurs années dans le domaine de la conservation de la Nature, mais souffre du manque de moyens nécessaires pour entretenir et développer son potentiel faunique. En 1996, le Burkina Faso s’est engagé dans une réforme inédite dans ce pays visant à ouvrir la gestion de la faune au secteur privé. Cet article présente à travers l’exemple de la Zone de Chasse de Konkombouri comment le concessionnaire a pu, en mettant en œuvre un certain nombre d’aménagements et certaines activités de gestion de terrain, redynamiser la faune qui s’est multipliée par 3 en 12 ans et comment l’activité de grande chasse a pu créer une dynamique économique favorable à l’Etat, aux communautés locales et aux prestataires de services locaux et étrangers. L’analyse économique compare également les résultats économiques de la ZCK à d’autres zones de chasse d’Afrique Centrale et de l’Ouest. [less ▲]

We show how to represent an interval of real numbers in an abstract numeration system built on a language that is not necessarily regular. As an application, we consider representations of real numbers using the Dyck language. We also show that our framework can be applied to the rational base numeration systems. [less ▲]

This review focuses on carrion beetles (Coleoptera, Silphidae) of the Western Palearctic and their potential use in forensic entomology as bioindicators. Few studies have looked at Silphidae in forensic context and investigations. However, some Silphidae present the desirable characteristics of some Diptera used in postmortem estimates and thus may extend the minimum postmortem interval (PMImin). We review here the taxonomy and distribution of Western Palearctic Silphidae. The anatomical and morphological characteristics of both subfamilies are described for adults and larvae. The biology and ecology of silphids are also summarized for Silphinae and Nicrophorinae. A specific chapter gives an overview of the current uses of Silphidae in forensic entomology as postmortem indicator. [less ▲]

Objectives:Recent fMRI studies have shown that it is possible to reliably identify the default-mode network (DMN) in the absence of any task, by resting-state connectivity analyses in healthy volunteers. We here aimed to identify the DMN in the challenging patient population of disorders of consciousness encountered following coma. Experimental design: A spatial independent component analysis-based methodology permitted DMN assessment, decomposing connectivity in all its different sources either neuronal or artifactual. Three different selection criteria were introduced assessing anticorrelation-corrected connectivity with or without an automatic masking procedure and calculating connectivity scores encompassing both spatial and temporal properties. These three methods were validated on 10 healthy controls and applied to an independent group of 8 healthy controls and 11 severely brain-damaged patients [locked-in syndrome (n = 2), minimally conscious (n = 1), and vegetative state (n = 8)]. Principal observations: All vegetative patients showed fewer connections in the default-mode areas, when compared with controls, contrary to locked-in patients who showed near-normal connectivity. In the minimally conscious-state patient, only the two selection criteria considering both spatial and temporal properties were able to identify an intact right lateralized BOLD connectivity pattern, and metabolic PET data suggested its neuronal origin. Conclusions: When assessing resting-state connectivity in patients with disorders of consciousness, it is important to use a methodology excluding non-neuronal contributions caused by head motion, respiration, and heart rate artifacts encountered in all studied patients.
