La préparation de l'échantillon est une étape clé et indispensable au dosage de l'analyte dans la matrice solide. Les principes de base et applications des procédés dits "conventionnels" (macération, percolation et soxhlet) et "modernes" (micro-ondes,assistée par solvant et en phase supercritique) sont repris dans le document. Compte tenu de l'utilisation et des avantages de l'extraction par les fluides supercritiques, ce procédé est présenté plus en détails. [less ▲]

Les recherches académiques dans le domaine du bioraffinage sont présentées au travers de schémas complets de valorisation. Les matières premières ciblées sont les résidus agricoles et forestiers, les cultures énergétiques et les résidus des industries alimentaires. Le cracking et la conversion ultérieure de ces matières premières permettent l'obtention de biocarburants, bioproduits ou nouvelles formulations (filière biomasse-chimie). [less ▲]

Very High Resolution (VHR) satellite images offer a great potential for the extraction of landuse and land-cover related information for urban areas. The available techniques are diverse and need to be further examined before operational use is possible. In this paper we applied two pixel-by-pixel classification techniques and the object-oriented image analysis approach (eCognition) for a land-cover classification of a Quickbird image of a study area in the northern part of the city of Ghent (Belgium). Only small differences in overall Kappa were noted between the best results of the pixel-based approach (neural network classification with Haralick texture measures) and the object-oriented classification (eCognition). A rule-based procedure using ancillary information on elevation derived from a digital surface model was applied on the pixel-based land-cover classification in order to obtain information on the spatial distribution of buildings and artificial surfaces.

Wearable inertial systems often require many sensing units in order to reach an accurate extraction of temporal gait parameters. Reconciling easy and fast handling in daily clinical use and accurate extraction of a substantial number of relevant gait parameters is a challenge. This paper describes the implementation of a new accelerometer-based method that accurately and precisely detects gait events/parameters from acceleration signals measured from only two accelerometers attached on the heels of the subject’s usual shoes. The first step of the proposed method uses a gait segmentation based on the continuous wavelet transform (CWT) that provides only a rough estimation of motionless periods defining relevant local acceleration signals. The second step uses the CWT and a novel piecewise-linear fitting technique to accurately extract, from these local acceleration signals, gait events, each labelled as heel strike (HS), toe strike (TS), heel-off (HO), toe-off (TO), or heel clearance (HC). A stride-by-stride validation of these extracted gait events was carried out by comparing the results with reference data provided by a kinematic 3D analysis system (used as gold standard) and a video camera. The temporal accuracy ± precision of the gait events were for HS: 7.2 ms ± 22.1 ms, TS: 0.7 ms ± 19.0 ms, HO: ‒3.4 ms ± 27.4 ms, TO: 2.2 ms ± 15.7 ms, and HC: 3.2 ms ± 17.9 ms. In addition, the occurrence times of right/left stance, swing, and stride phases were estimated with a mean error of ‒6 ms ± 15 ms, ‒5 ms ± 17 ms, and ‒6 ms ± 17 ms, respectively. The accuracy and precision achieved by the extraction algorithm for healthy subjects, the simplification of the hardware (through the reduction of the number of accelerometer units required), and the validation results obtained, convince us that the proposed accelerometer-based system could be extended for assessing pathological gait (e.g., for patients with Parkinson’s disease).

STUDY DESIGN: This is a report of a case. OBJECTIVE: To document the clinical, radiographic, and histologic characteristics of a lumbar extraforaminal juxtafacet cyst. SUMMARY OF BACKGROUND DATA: Spinal juxtafacet cysts develop most frequently at the dorsal aspect of the zygapophysial joint, sometimes in the posterolateral area of the canal. In one case, they have been described in the foraminal and extraforaminal region. METHODS: Description of the case report. RESULT: The authors report one case of a strictly extraforaminal juxtafacet cyst responsible for L5 sciatica. CONCLUSIONS: Juxtafacet cysts of the spine represent an infrequent cause of sciatica, usually when they grow in the canal, or more exceptionally when they occupy the foraminal or extraforaminal areas.
