In the first part of this paper, we discuss the effects of grain boundaries on the properties of bulk colossal magnetoresistive (CMR) manganites We compare the electrical resistivity and AC magnetic susceptibility of perovskite La-Ca-Mn-O samples with the same nominal stoichiometry but differing in their microstructure (i) a single grain sample, (ii) a sample containing two grains and (iii) a polycrystalline sample Emphasis is placed on information that can be deduced from the measurements in each case In the second part of the paper, we report the data measured on composite samples containing a CMR phase (La-Ca-Mn-O) and an insulating phase (Mn3O4) The results are discussed in the framework of percolation theory We show how the grain boundaries affect the electrical properties of these materials, and we highlight the crucial role of geometric (demagnetization) effects on the resistance vs magnetic field measurements [less ▲]

Background: Cardiac resynchronization therapy (CRT) provides benefit for congestive heart failure, but still 30% of patients failed to respond to such therapy. This lack of response may be due to the presence of significant amount of scar or fibrotic tissue at myocardial level. This study sought to investigate the potential impact of myocardial contractile reserve as assessed during exercise echocardiography on acute response following CRT implantation. Methods: Fifty-one consecutive patients with heart failure (LV ejection fraction 27% ± 5%, 67% ischemic cardiomyopathy) underwent exercise Doppler echocardiography before CRT implantation to assess global contractile reserve (improvement in LV ejection fraction) and local contractile reserve in the region of the LV pacing lead (assessed by radial strain using speckle tracking analysis). Responders were defined by an increase in stroke volume ≥15% after CRT. Results: Compared with nonresponders, responders (25 patients) showed a greater exercise-induced increase in LV ejection fraction, a higher degree of mitral regurgitation and a significant extent of LV dyssynchrony. The presence of contractile reserve was directly related to the acute increase in stroke volume (r = 0.48, p<0.001). Baseline myocardial deformation as well as contractile reserve in the LV pacing lead region was greater in responders during exercise than in nonresponders (p<0.0001). Conclusions: Heart failure patients referred to CRT have less chance of improving under therapy if they have no significant mitral regurgitation, no LV dyssynchrony and no contractile myocardial recruitment at exercise.

Abstract Background. Patients with chronic kidney disease stage 5 have a high prevalence of vascular calcification, but the specific anatomical distribution and severity of abdominal aortic calcification (AAC), in contrast to coronary calcification, is less well documented. AAC may be recorded using plain radiographs. The present report is an analysis of baseline data on AAC in patients enrolled in the CORD (Calcification Outcome in Renal Disease) study. Methods. A total of 47 centres in six European countries participated in this cross-sectional study. Inclusion criteria were age ≥18 years and duration of dialysis ≥3 months. Lateral lumbar radiography of the abdominal aortawas used to determine the overall AAC score, which is related to the severity of calcific deposits at lumbar vertebral segments L1–L4. The reliability of the method was tested by double reading of 64 radiographs (coefficient of correlation 0.9). Results. A lateral lumbar radiograph was obtained in 933 patients. Calcification (AAC score ≥ 1) was present in 81% of the patients; its severity increased significantly from L1 to L4 (P < 0.0001) and affected all of these segments in 51% of patients. Independent predictors for the presence and severity of calcification were age (odds ratio [OR] 1.103/year; P < 0.0001), duration of dialysis (OR 1.110/year; P = 0.002) and history of cardiovascular disease (OR 3.247; P < 0.0001). Conclusions. AAC detected by lateral lumbar radiograph is associated with several risk factors of uraemic calcification. This semi-quantitative method is more widely available and less expensive than the current procedures for studying calcification and could formpart of a pre-transplantworkup and cardiovascular risk stratification.

La place du réchauffement climatique dans les médias, dans les préoccupations des citoyens et dans le débat politique est sans cesse croissante, tout comme l’est la concentration en dioxyde de carbone (CO2) dans l’atmosphère. Le Prix Nobel de la Paix attribué en 2007 à l’ancien vice-président américain Al Gore et au Groupe d’experts intergouvernemental sur l’étude du climat (GIEC) est par ailleurs très significatif de l’importance de l’enjeu. Dans les semaines précédant Noël, nous avons décortiqué les publicités de notre hypermarché le plus proche (Carrefour) pour préparer le repas familial tant attendu. Et voici ce que nous avons pu concocter pour huit personnes avec, entre parenthèses, les kilomètres parcourus entre le pays de production et la Belgique, le mode de transport utilisé pour importer ces aliments (A = avion, B = bateau), ainsi que les kilogrammes de CO2 émis uniquement pour le transport intercontinental de ces produits achetés. Rappelons que l’avion émet, en moyenne, 60 fois plus de CO2 que le transport par voie maritime. [...] [less ▲]

Discrete Naive Bayes models are usually defined parametrically with a map from a parameter space to a probability distribution space. First, we present two families of algorithms that compute the set of parameters mapped to a given discrete Naive Bayes distribution satisfying certain technical assumptions. Using these results, we then present two families of parameter learning algorithms that operate by projecting the distribution of observed relative frequencies in a dataset onto the discrete Naive Bayes model considered. They have nice convergence properties, but their computational complexity grows very quickly with the number of hidden classes of the model. [less ▲]

Assessing the microbial contamination level of surfaces is critical in environments where high hygiene levels are required. This is typically the case in food and catering industries or in hospitals and medical appliances. On a routine base, RODAC plates and other techniques based on microbial transfer are generally used to quantify the microbial load of a surface. There are however still polemics on the limitations and performances of these techniques arising from the fact that the initial contamination level of a surface is never known and due to the difficulty of reproducing field conditions in laboratory environments. The present study brings further information in that direction. [less ▲]

Cet article interroge la relation intermédiale entre peinture et photographie, et notamment la transformation des pratiques de réception liées à la transduction de certaines iconographies religieuses d’un médium à l’autre. Il décrit les effets de sens que les textes picturaux et photographiques engendrent lorsqu’ils sont censés représenter non seulement l’invisible, mais aussi la transcendance. Si la peinture religieuse a toujours été légitimée à représenter Jésus-Christ, les saints et les visions de l’au-delà, la photographie artistique a au contraire subi des « contraintes interprétatives » attribuées par la doxa à sa genèse à empreinte. Si la doxa a donc relégué les textes photographiques artistiques à la seule fonction de représenter l’« ici-et-maintenant », le cas de la photo dévotionnelle est différent. En effet, la photographie dévotionnelle, engendrant des pratiques productives, interprétatives et communicationnelles tout à fait différentes de celles de la photo artistique, a mis en scène une autre conception du médium photographique, qui le met en communication étroite avec la syntaxe figurative de l’icône, ou même avec le saint suaire de Turin – image qui n’est pas faite de main d’homme (acheiropoïètes) et qui devient support d’une révélation sans médiation.

Hydrogen has received wide attention in the last decade as a clean energy vector. The major advantage of energy from hydrogen is the zero carbon emissions, since the utilization of hydrogen, either via combustion or via fuel cells, results in pure water. At industrial scale, steam reformation of methane is currently the major hydrogen producing process. However recently, increasing interest has been paid on biological production of hydrogen gas. Indeed, biohydrogen generation from renewable biomass would reduce dependence on fossil fuel, decrease the carbon dioxide emissions and produce usable bioenergy. Biological production of hydrogen using anaerobic bacteria is an exciting and promising new area of technology development that offers the potential production of usable hydrogen from a variety of renewable resources such as carbohydrates from agriculture or agro-food industries. This biological system is called dark fermentation and the most interesting bacteria strains are Clostridium sp. The investigations carried out at CWBI involve selection and characterization of bacteria strains, optimization of the biotechnological process and design of highly efficient bioreactors. [less ▲]
