The Hybrid Finite Element Mixing Cell (HFEMC) method is a flexible modelling technique particularly suited to mining problems. The principle of this method is to subdivide the modelled zone into several subdomains and to select a specific equation, ranging from the simple linear reservoir equation to the groundwater flow in porous media equation, to model groundwater flow in each subdomain. The model can be run in transient conditions, which makes it a useful tool for managing mine closure post-issues such as groundwater rebound and water inrushes. The application of the HFEMC method to an abandoned underground coal mine near the city of Liege (Belgium) is presented. The case study zone has been discretized taking advantage of the flexibility of the method. Then, the model has been calibrated in transient conditions based on both hydraulic head and water discharge rate observation and an uncertainty analysis has been performed. Finally, the calibrated model has been used to run several scenarios in order to assess the impacts of possible future phenomena on the hydraulic heads and the water discharge rates. Among others, the simulation of an intense rainfall event shows a quick and strong increase in hydraulic heads in some zones coupled with an increase in associated water discharge rates. This could lead to stability problems in local hill slopes. These predictions will help managing and predicting mine water problems in this complex mining system. [less ▲]

[Bi1.68Ca2O4](RS)[CoO2](1.69) (BCCO) sample and Ag-BCCO composites (with 10, 20 or 30 wt% Ag) have been prepared by the spray-drying technique and uniaxially/isostatically packed. Scanning electron microscopy reveals that the Ag particles are well distributed in the BCCO cobaltite matrix at low Ag contents. The Ag particles have an important effect on densification and grain orientation of the samples, with a direct impact on their electrical conductivity. The electrical conductivity is higher for the uniaxial samples and increases with the Ag content up to 20% in weight, while the Seebeck coefficient is hardly affected. These features induce an improvement of the power factor, reaching a maximum value of 2.2 mu W K-2 cm(-1) at similar to 1050 K for the uniaxial sample with 20 wt% Ag. Our results suggest that the spray-drying technique is a promising method to obtain composites with a well-dispersed secondary phase. (C) 2010 Elsevier Masson SAS. All rights reserved. [less ▲]

AIM: This study aimed to assess the effectiveness of continuous glucose monitoring (CGM) for glucose control in type 1 diabetic patients treated by continuous subcutaneous insulin infusion (CSII) and presenting with frequent hypoglycaemic episodes. METHODS: Thirteen patients with type 1 diabetes (diabetes duration: 25+/-15 years; CSII duration: 5.5+/-7.0 years), with more than six recorded capillary blood glucose (CBG) values <60 mg/dL, according to their metres for the past 14 days, were offered the permanent use of a CGM device (Guardian RT((R)), Medtronic) plus ongoing self-monitoring of blood glucose (SMBG) for 12 weeks, followed by a 12-week crossover period of SMBG only, or vice versa. Glucose control, determined by recorded 14-day CBG values <60 mg/dL and HbA(1c) levels, and quality of life according to the Diabetes Quality of Life (DQOL) questionnaire, were assessed at baseline, and after 12- and 24-week follow-ups. RESULTS: Four patients withdrew from the study during the first period (of whom three were using CGM). In the nine study completers, the number of low CBG values decreased significantly from 13.9+/-9.2 to 7.6+/-6.8 (P=0.011) when patients used CGM, in either the initial or final trial period, while a decrease in HbA(1c) from 8.3+/-0.7 to 7.7+/-0.6% (P=0.049) was also observed, in contrast to the absence of any significant differences during the SMBG-only period. DQOL scores were also essentially unaffected. CONCLUSION: This pilot observational study supports the hypothesis that CGM use can significantly improve overall glucose control while reducing hypoglycaemic episodes in hypoglycaemia-prone type 1 diabetic patients treated by CSII.

Abstract — Academic texts on agro-ecology are often too limited to production systems. When notions of food systems and food value chains are described they introduce the consumer as a choice taker, reflecting neoclassical economic theory. The study of the emergence of two agro-ecological chains in Benin and Belgium explains how consumer demands are key learning resources for chain co-creation. In the case of the fair trade rice chain an NGO stimulates the co-creation process while in the beef chain in Gaume consumers who are directly involved in a deliberative process bring about this questioning.

Stroke is a leading cause of death worldwide and the most common cause of long-term disability amongst adults, more particularly in patients with diabetes mellitus and arterial hypertension. Increasing evidence suggests that disordered physiological variables following acute ischaemic stroke, especially hyperglycaemia, adversely affect outcomes. Post-stroke hyperglycaemia is common (up to 50% of patients) and may be rather prolonged, regardless of diabetes status. A substantial body of evidence has demonstrated that hyperglycaemia has a deleterious effect upon clinical and morphological stroke outcomes. Therefore, hyperglycaemia represents an attractive physiological target for acute stroke therapies. However, whether intensive glycaemic manipulation positively influences the fate of ischaemic tissue remains unknown. One major adverse event of management of hyperglycaemia with insulin (either glucose-potassium-insulin infusions or intensive insulin therapy) is the occurrence of hypoglycaemia, which can also induce cerebral damage. Novel insights into post-stroke hyperglycaemia management have been derived from continuous glucose monitoring systems (CGMS). This article aims: 1) to describe the adverse effects of hyperglycaemia following acute ischaemic stroke and the risk associated with iatrogenic hypoglycaemia; 2) to summarise the evidence from current glucose-lowering treatment trials; and 3) to show the usefulness of CGMS in both non-diabetic and diabetic patients with acute stroke.

Staphylococcus (S.) aureus is a major pathogen for mastitis in dairy cattle. In most cases, S. aureus causes long-lasting subclinical and chronic bovine mastitis and leads to significant economic losses by reducing the quantity and the quality of the milk produced. The pathogenesis of S. aureus mastitis includes the ability to persist within host cells and involves multiple virulence factors including toxins, surface proteins and polysaccharides. The numerous vaccines that have been developed induce a specific immune response against these different factors. These different vaccine approaches are described and classified depending on the target antigen used. Moreover, some recent vaccine strategies against human S. aureus infections are also discussed and could eventually be used for the design of new bovine vaccines. Although most of bovine vaccines induce specific humoral response, to date, no vaccine has been described to protect efficiently against experimental and naturally occurred bovine S. aureus mastitis. In conclusion, this type of immune response and the broad antigenic variability of S. aureus strains can partially explain the lack of protection observed during most of vaccine trials. [less ▲]

It’s known that sexual health of people with psychiatric and psychological disorders is often highly impoverished. Mental health professionals may feel helpless against these sexual difficulties, because of being poorly trained to treat them and lacking the means to do it. In this context, it seems important to inform patients about sexual difficulties and treatment options. Although it’s impossible to assign a sex therapist to each mental health service, it could be very useful to use bibliotherapeutic documentation to guide people with sexual difficulties in finding solutions. This mode of treatment which consists in putting information and therapeutic guidelines on writing is called « bibliotherapy ». Some bibliotherapies have already been developed and tested in the field of sexual disorders. Others, experimental, are nowadays under clinical evaluation, notably by three of the authors of the present paper. Bibliotherapy could be a helpful adjunct in improving the sexual health of dayhospital patients. [less ▲]

Io's motion relative to the Jovian magnetic field generates a power of about 10^12 W, which is thought to propagate as an Alfven wave along the magnetic field line. This power is transmitted to the electrons, which will then precipitate and generate the observed auroral phenomena from UV to radio wavelengths. A more detailed look at this hypothesis shows some difficulties: Can the Alfven waves escape the torus or are they trapped inside? Where and how are the particles accelerated? In which direction? Is there enough power transmitted to the particles to explain the strong brightness of the auroral emissions in UV, IR, visible, and radio? In other words, can we make a global, consistent model of the Io-Jupiter interaction that matches all the observations? To answer these questions, we review the models and studies that have been proposed so far. We show that the Alfven waves need to be filamented by a turbulent cascade process and accelerate the electrons at high latitude in order to explain the observations and to form a consistent scheme of the Io-Jupiter interaction.

Sur fond de déclin des industries typographiques héritées du XIXe siècle et d'extinction progressive de l'activité éditoriale de la maison Marabout, l'édition en région liégeoise s'est redéployée, à partir des années 1970, des trois côtés du livre de sciences humaines et d'architecture (Mardaga), des arts visuels et cinématographiques (Yellow Now) et du livre de poésie (Atelier de l'Agneau, Tétras-Lyre, L'Arbre à Paroles, Le Fram). Le genre romanesque y reste quant à lui relégué dans des niches régionalistes (Dricot), occupées aussi par des imprimeurs de livres de terroir (éditions du Perron, Noir Dessin, etc.). Une tendance esthétique générale se dessine chez ces différents éditeurs : la production de formes hybrides et de livres produits à l'intersection de plusieurs champs symboliques, tendance que prolonge jusqu'à nos jours un Luc Pire, éditeur de livres d'actualité et pionnier du livre numérique en Belgique francophone.
