Sulphides with chemical compositions between idaite and bornite have been identified from several quartz veins crosscutting Ordovician schists in Vielsalm, Belgium. Idaite is an oxidation product of bornite, and occurs in the more oxidised parts of the quartz veins. The alteration sequence bomite --> "anomalous bornite" --> idaite is observed, associated with the growth of chalcopyrite lamellae parallel to the {100} and {111} directions of precursor bornite. Electron microprobe analyses indicate a chemical composition significantly enriched in Cu, when compared with the ideal composition of idaite, Cu3FeS4, as well as a progressive compositional evolution from bomite to idaite. The X-ray powder pattern is indexed in the space group I (4) over bar 2m, similar to that of stannite, and gives the unit-cell parameters a = 5.279(4) and c = 10.47(2) Angstrom. [less ▲]

Porcine stress syndrome is related to a point mutation in Ryr1 gene encoding the ryanodin receptor. This syndrome involves mortality after stress conditions or poor quality meat. Five hundred and five individuals among 5 Belgian production systems were genotyped. This genotyping was performed by polymerase chain reaction-restriction fragment length polymophism (PCR-RFLP) or real time PCR. The results indicated that 22,4 % of the pigs were stress sensitive (TT genotype) and 77,6 % stress resistant (63,4 % CT heterozygotes and 14,2 % CC genotype). Statistical analysis allowed to split the production systems into two groups: the production system 1 and 2 presenting a high level of TT individuals (44 % and 52 % respectively) although production systems 3, 4 and 5 presented a high level of heterozygotes individuals (74 %, 92 % and 78 % respectively). At the technical level, real time PCR appeared to be a faster and an easier technique than PCR-RFLP. [less ▲]

STUDY DESIGN: Case report of a 71-year-old man having sustained a spinal cord injury (SCI) for 26 years. He started to suffer from low back pain 21 years after his onset and this was diagnosed as ilio-lumbar syndrome (ILS). OBJECTIVES: To describe the problem of low back pain occurring after a change of wheelchair in a SCI, and to indicate the importance of the ilio-lumbar syndrome as a possible cause of low back complaint. OUTCOME: Clinical findings supported by echotomography confirmed the diagnosis of ILS in our case. CONCLUSION: ILS should be considered when some changes and deterioration of the status of SCI occur due to low back complaint. [less ▲]

The Asian ladybird, Harmonia axyridis Pallas (Coleoptera: Coccinellidae), was imported in 1997 in Belgium to control aphid populations in greenhouses. It took only few years to the insect to get adapted to temperate climate conditions and to spread out all over Europe. Now, H. axyridis is one of the coccinellid with the biggest size in Belgium, causing damages to the ecosystems through e.g. intraguild predation (IGP). We are still lacking information about the consequences of the introduction of this superpredator in our agro-ecosystems. This work focuses on the potential impacts of H. axyridis on the entomofauna associated with several crops (potatos, corn, wheat, broad bean). We evaluated in 2009 the occurrence as well as the interactions between aphids and their natural enemies (hoverflies, coccinellids and lacewings) in several agro-ecosystem sites in northern Wallonia. After one year of field observations, were found thirteen coccinellid species, most of the catched individuals being H. axyridis with 64% of the coccinellids, Propylea 14-punctata, 15%, or Coccinella 7-punctata, 14%. This invasive ladybird dominates the group of coccinellids generally in all crops in north Wallonia. The results with the sticky traps show that the maximum occurrence of H. axyridis in crops is observed in chicory, sugar beet and potatoes. The relationship aphid-ladybird in wheat for example, brings out that increase of density of Asian ladybird in mid-July follow the increase of aphids (Sitobion avenae, Sitobion fragariae, Metopolophium dirhodum, Aphis fabae) in the end of June. We also observe that, in most agro-ecosystems, hoverflies and lacewings are the dominant aphid natural enemies. In all crops investigate, the multicolored ladybird occurs with 5% of the aphidophagous after the Chrysopidae, 12% and the Syrphidae, 76%. In 2009, the agro-ecosystems with the most aphidophagous species are carrot and broad bean and these habitats are dominated by hoverflies. [less ▲]

Large discrepancies exist among data-based estimates and model reconstructions of the ocean bomb radiocarbon inventory. In order to resolve this gap, it has been proposed that the CO2 piston veloc- ity should be revised downward (Sweeney et al., 2007; Müller et al., 2008). Here we compare the transient 14C distributions in the ocean obtained with different formulations of the isotopic ratio commonly used in modeling studies. It is found that both the CO2 increase and the air-sea CO2 flux significantly contribute to the 1990 ocean bomb radiocarbon inventory, by around 10% each. Moreover, these two processes explain more than 25% of the inventory difference be- tween 1974 and 1990. These results imply that, as already argued by Naegler (2009), inventories based on observations which lack infor- mation about CO2 invasion are underestimated. Further, this work allows to gain insight into the reasons for discrepancies among model results. It suggests that while a comprehensive isotopic formulation is needed when addressing the global radiocarbon cycle, a simplified form is more relevant for model calibration and piston velocity assess- ment based on currently available bomb radiocarbon inventories.

L’ouvrage de Luigi Cancrini, l’Océan Borderline, et le regard nouveau, complexe et intégré qu’il propose nous semble une ressource intéressante et riche pour la prise en charge et la réflexion sur les situations cliniques de maltraitance. Au sein de son ouvrage où il conceptualise les troubles borderline sous la forme d’un océan entouré de deux continents, la névrose et la psychose, l’auteur défend l’idée que les difficultés psychopathologiques des individus se référeraient bien plus à un fonctionnement contextuel et ponctuel qu’à une structure fixe et atemporelle de la personnalité.

A variable-resolution atmospheric general circulation model (AGCM) is used for climate change projections over the Antarctic. The present-day simulation uses prescribed observed sea-surface conditions, while a set of five simulations for the end of the 21st century (2070-2099) under the SRES-A1B scenario uses sea- surface condition anomalies from selected CMIP3 coupled ocean-atmosphere climate models. Analysis of the results shows that the prescribed sea-surface condition anomalies have a very strong influence on the simulated climate change on the Antarctic continent, largely dominating the direct effect of the prescribed greenhouse gas concentration changes in the AGCM simulations. Complementary simulations with idealized forcings confirm these results. An analysis of circulation changes using self-organizing maps shows that the simulated climate change on regional scales is not principally caused by shifts of the frequencies of the dominant circulation patterns, except for precipitation changes in some coastal regions. The study illustrates that in some respects the use of bias-corrected sea- surface boundary conditions in climate projections with a variable-resolution atmospheric general circulation model has some distinct advantages over the use of limited-area atmospheric circulation models directly forced by generally biased coupled climate model output.
