La recherche ‘Flexihealth’, portant sur 4961 travailleurs belges, vise à établir un lien entre les changements majeurs, la perception des modifications des conditions de travail qu’ils impliquent et le bien-être des travailleurs. Les résultats montrent que les changements vécus ont un impact négatif significatif non seulement sur les conditions de travail mais aussi sur le bien-être des travailleurs. Ce résultat doit toutefois être nuancé selon le type de changement vécu. En ce sens, le changement de supérieur et le changement de tâches sont davantage préjudiciables pour les travailleurs. L’âge et la catégorie professionnelle des travailleurs sont également des variables considérées pour nuancer ces résultats. Ainsi, les travailleurs âgés de 46 à 55 ans ainsi que les ouvriers constituent des groupes à risques. [less ▲]

The purpose of the study was to investigate the possible effect of an environmental organochlorine, dichlorodiphenyldichloroethylene (p,p'-DDE), on male fertility assessed by main sperm variables, conducted through a case-control study on young men attending the andrology laboratory in the context of infertility investigation in the couple. Blood and semen samples were obtained from 73 young men considered as fertile based on semen analysis (controls) and 82 classified as subfertile or unfertile (cases). Standard clinical analysis of semen was performed and identification and quantification of p,p'-DDE in serum and in seminal plasma were done by gas chromatography. No p,p'-DDE was detected in the seminal plasma of either group. Blood concentration of p,p'-DDE in both groups was very low and did not differ between cases and controls; however, blood samples were obtained from 23 mothers in the control group, and from 19 in the case group, and p,p'-DDE serum level was significantly higher in the mothers of subfertile men. These data suggest that male infertility could be associated with exposure of the mothers to p,p'-DDE with deleterious effects restricted to intra-uterine life and thus undetected in blood or seminal plasma of subfertile men.

After a brief reminding of the synthesis and function of coenzyme Q10, this article tries to summarise the current state of knowledge about the consequences of its deficiency and about the potential benefits of an increased intake of this coenzyme. We then describe the arguments in favour of such an increase in cardiac diseases and in Parkinson's disease. [less ▲]

The quantum theory of the cold-atom micromaser including the effects of gravity is considered. We show that gravity does not break the special properties of the induced emission probability for the micromaser in the cold atom regime and rather new effects are predicted. In particular, we show that the cavity acts in the gravity field as an additional repulsive and attractive potential, resulting in quasibound states of the atomic motion. This feature gives rise to fine resonances in the induced emission probability that are not restricted to any particular cavity mode function, in contrast to the usual cold-atom micromaser. It is also shown that the atom is able to emit a photon inside the cavity, though classically it does not reach the interaction region. Predictions about the photon number statistics when the cavity is pumped by a flux of excited atoms are finally given. Unusual highly nonclassical "dragon" distributions are still predicted in the vertical geometry. (c) 2005 American Institute of Physics. [less ▲]

Fumonisin B(1) (FB(1)) is a mycotoxin produced by Fusarium verticillioides and F. proliferatum that commonly occurs in maize. In swine, consumption of contaminated feed induces liver damage and pulmonary edema. Pasteurella multocida is a secondary pathogen, which can generate a respiratory disorder in predisposed pigs. In this study, we examined the effect of oral exposure to fumonisin-containing culture material on lung inflammation caused by P. multocida. Piglets received by gavage a crude extract of fumonisin, 0.5mg FB(1)/kg body weight/day, for 7 days. One day later, the animals were instilled intratracheally with a non toxin producing type A strain of P. multocida and followed up for 13 additional days. Pig weight and cough frequency were measured throughout the experiment. Lung lesions, bronchoalveolar lavage fluid (BALF) cell composition and the expression of inflammatory cytokines were evaluated at the autopsy. Ingestion of fumonisin culture material or infection with P. multocida did not affect weight gain, induced no clinical sign or lung lesion, and only had minimal effect on BALF cell composition. Ingestion of mycotoxin extract increased the expression of IL-8, IL-18 and IFN-gamma mRNA compared with P. multocida infection that increased the expression of TNF-alpha. The combined treatment with fumonisin culture material and P. multocida delayed growth, induced cough, and increased BALF total cells, macrophages and lymphocytes. Lung lesions were significantly enhanced in these animals and consisted of subacute interstitial pneumonia. TNF-alpha, IFN-gamma and IL-18 mRNA expression was also increased. Taken together, our data showed that fumonisin culture material is a predisposing factor to lung inflammation. These results may have implications for humans and animals consuming FB(1) contaminated food or feed. [less ▲]

A la veille de la Première Guerre mondiale, les gouvernements de Bruxelles et Berlin négocient la création de nouvelles lignes de chemins de fer entre la Belgique et l'Allemagne. En outre, les régions rurales de l'Ardenne belge et de l'Eiffel allemande se dotent d'un vaste réseau ferroviaire. L'extension considérable des moyens de communication entre la Belgique et l'Allemagne attire l'attention des autorités militaires françaises qui tardent cependant à prendre en considération cette nouvelle menace stratégique sur leur frontière nord.

Construction waste management is a quite important economical and environmental deal for our societies. More than 2 million tons are annually produced in Wallonia, South Region of Belgium, and numerous valorisations have been already promoted. Roller Compacted Concrete is a special dry concrete made of aggregates, water and low quantity of cement, laid down and compacted like a soil, for the construction of massive structures like dams or large horizontal surfaces like road foundations. The topic of this research is the replacement of natural aggregates by concrete recycled aggregates in the composition of the concrete. Characteristics of aggregates are of prime importance for the quality of the concrete: Los Angeles, water absorption and specific gravity are measured. Design method, type of hydraulic binder and proportions have to be adapted. Final and long term properties have also been evaluated. [less ▲]

This paper aims at analyzing Polish and Spanish approach to the European Neighbourhood Policy in comparative perspective in order to assess their degree of competition and complementarity since these factors will in great manner determine the ability of the EU to create a true “ring of friends” in its neighbourhood. The paper analyzes Polish and Spanish visions of their respective neighbourhood environment; their proposals relative to the EU’s Southern and Eastern Dimensions and the mechanisms used by Poland and Spain in order to promote their neighbourhood policy preferences in the framework of the EU foreign policy system.
