Outcomes for neurosurgery patients can be improved by enhancing intraoperative navigation and guidance. Current navigation systems do not accurately account for intraoperative brain deformation. So far, most studies of brain deformation have focused on brain shift, whereas this paper focuses on the brain deformation due to retraction. The heart of our system is a 3D nonrigid registration technique using a biomechanical model driven by the deformations of key surfaces tracked between two intraoperative images. The key surfaces, e.g., the whole-brain region boundary and the lips of the retraction cut, thus deform due to the combination of gravity and retractor deployment. The tissue discontinuity due to retraction is handled via the eXtended Finite Element Method (XFEM), which has the appealing feature of being able to handle arbitrarily shaped discontinuity without any remeshing. Our approach is shown to significantly improve the alignment of intraoperative MRI. [less ▲]

In this paper, we report on the use of a high energy and high resolution X-ray tomograph to visualize and quantify the distribution of liquid hold up and of gas-liquid interfacial area in a 0.1m diameter column filled with MellapakPlus 752.Y packing elements. A standard air-water system at room temperature and atmospheric pressure was used. Tomographic measurements have been carried out in a large number of packing cross sections situated at different heights between the top and the bottom of the packed column, giving access to the evolution of axial profiles of liquid hold up and of gas-liquid interfacial area as a function of the operating conditions. Gas-liquid interfacial area values were also measured by a chemical method (CO2 absorption from air into a caustic solution). For the first time, a whole set of gas-liquid interfacial area values evaluated from tomographic images are interestingly compared with values measured by a chemical method. A comparison is also presented with literature models. [less ▲]

INTRODUCTION: Squatting is an active posture test that can be used to assess baroreflex sensitivity. Indeed, the shift from squatting to standing imposes a major orthostatic stress leading to rapid and large changes in arterial blood pressure (BP) and heart rate (HR) allowing precise baroreflex assessment. MATERIAL AND METHODS: BP and HR can be continuously and non-invasively monitored with a Finapres device. RESULTS: The standing to squatting transition is accompanied by rises in BP, pulse pressure and cardiac output, mainly due to increased venous return, and by a secondary reduction in HR. Conversely, the squatting to standing transition is associated with an immediate drop in BP and both reflex tachycardia and vasoconstriction. This mirror changes in BP and HR, mimicking those observed with the classical pharmacological approach using vasopressor/vasodilating agents, allows the calculation of the so-called baroreflex gain. DISCUSSION: The present review describes the haemodynamic changes occurring in normal subjects during the shifts from standing to squatting and from squatting to standing and discusses the underlying cardiovascular and autonomic mechanisms. CONCLUSION: This careful analysis in healthy individuals should help in the understanding of disturbances that may be observed in patients with autonomic dysfunction, such as in diabetic patients with cardiovascular autonomic neuropathy.

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.
