Nase (Chondrostoma nasus) and common barbel (Barbus barbus) are two rheophilic cyprinid fish naturally present in the Belgian Meuse and Rhine basins. During the last decades, the construction of dams together with changes in hydrological regimes, modifications of riverbed morphology and water pollution have caused some local dramatic declines in their populations. However, recent improvements in terms of water quality and habitat fragmentation allow considering as realistic a rational restocking plan of locally endangered patrimonial fish species such as nase and common barbel. Restocking operations for a conservation purpose have to be based on the knowledge and the use of wild type genetic strains. Therefore, the aim of this study was to characterize the genetic structure and diversity of nase and common barbel populations in South Belgium rivers. Wild common barbels (n = 313) and nases (n = 271) were sampled by electrofishing in respectively 10 and 6 different tributaries from the Meuse and Rhine rivers. Genotyping was performed on 24 microsatellite markers for each species. Preliminary results showed, for both species, a differential genetic clustering between fish originating from the Meuse basin and those originating from the Rhine basin. Detailed analysis describing the genetic structure and diversity of South Belgium populations will be presented and will serve as a management tool to set up a breeding plan for conservation restocking.

This article has two aims. Firstly, to introduce the important environmental inequality scholarship, mostly imported from the USA, in the Belgian context, where few studies have been carried out to date on this topic. Secondly, to propose an unconventional approach to environmental inequality scholarship by focusing on housing conditions as substantial environmental inequalities. On this latter premise, we based this study on the CEHD housing quality survey carried out in 2012 and 2013 in Wallonia, to test several hypotheses as regards the relationships between housing quality, poverty, and spatial differentiation – discrepancies among population and space. The results confirm most of our research hypotheses, showing important inequalities in terms of housing conditions between wealthy and poor populations, as well as between urban areas, on the one hand, and suburban and rural areas, on the other. Our findings call for new avenues and priorities for housing policies in Wallonia, and for further research on housing quality as environmental inequality: with a focus on a specific target public – single households, and on subjective perception of environmental nuisances in and surrounding home.

We introduce a new method for forecasting major El Niño/ La Niña events based on a wavelet mode decomposition. This methodology allows us to approximate the ENSO time series with a superposition of three periodic signals corresponding to periods of about 31, 43 and 61 months respectively with time-varying amplitudes. This pseudo-periodic approximation is then extrapolated to give forecasts. While this last one only resolves the large variations in the ENSO time series, three years hindcast as retroactive prediction allows to recover most of the El Niño/ La Niña events of the last 60 years.

Through their different encounters with union, court, and government equality agency lawyers, workers report diverse understandings of their personal experience of injustice in the workplace. This paper examines workers’ experiences of discrimination and the role legal professionals play in litigating these issues in Belgium. Bringing together legal and rights consciousness studies and the sociology of intermediation and tracking different stages in the construction of discrimination cases, from the moment when a future litigant describes an event as an injustice to the moment when the judge recognises a discriminatory behaviour (or conversely, dismisses a case), we suggest several possible empirical explanations of the way in which interactions with legal intermediaries affect workers’ rights consciousness. Because we refer to socio-legal studies from common law countries, this paper also calls into question how best to import these studies to assist in analysing legal mobilisations and legal consciousness in continental Europe.

Poly( N -vinylcaprolactam) (PNVCL) is a thermoresponsive and biocompatible polymer that raises an increasing interest in the biomedical area, especially in drug delivery systems (DDS) that include micelles, hydrogels, and hybrid particles. The thermoresponsiveness of PNVCL, used alone or in combination with other stimuli- responsive polymers or particles (pH, magnetic fi eld, or chemicals), is often key in the loading and/or release process in these DDS. The renewed focus on this polymer, which is known for decades, is to a large extent due to recent progress in synthetic strategies. Especially, the advent of efficient controlled radical polymerization (CRP) methods for NVCL monomer gives now access to unprecedented well-defi ned NVCL-based copolymers with unique properties. This Review article addresses up-to-date synthetic aspects, biological features, and biomedical applications of the latest NVCL-containing systems. [less ▲]

The Belgian severe asthma registry is a web-based registry encompassing demographic, clinical, functional and inflammatory data of severe asthmatics (SA), aiming at improving awareness, knowledge on its natural history and subphenotypes, and offering tools to optimize care of this asthma population. METHODS: The cross-sectional analyses of this registry included 350 SA as defined by the ATS (2000) from 9 Belgian centres, with at least one year follow up. RESULTS: Mean age was 55 +/- 14 yrs. SA were more frequently female (57%) and atopic (70%). Late-onset asthma (>/=40 yr) was observed in 31% of SA. Current smokers represented 12% while 31% were ex-smokers. In addition to high doses ICS + LABA, 65% of patients were receiving LTRA, 27% anti-IgE and 24% maintenance oral corticosteroids (8 mg (Interquartile range-IQR:4-8) methylprednisolone). Despite impaired airflow (median FEV1:67%; IQR: 52-81) only 65% had a post-bronchodilator FEV1/FVC ratio <70%. The median blood eosinophil count was 240/mm(3). The median FENO was 26 ppb (IQR: 15-43) and 22% of SA had FENO >/= 50 ppb. Induced sputum was successful in 86 patients. Eosinophilic asthma (sputum Eos >/= 3%) was the predominant phenotype (55%) while neutrophilic (sputum Neu >/= 76%) and paucigranulocytic asthma accounted for 22% and 17% respectively. Comorbidities included rhinitis and chronic rhinosinusitis (49%), nasal polyposis (19%), oesophageal reflux (36%), overweight and obesity (47%) and depression (19%). In addition, 8% had aspirin-induced asthma and 3% ABPA. Asthma was not well-controlled in 83% according to ACT < 20 and 77% with ACQ > 1.5. CONCLUSION: In this cohort of patients with severe asthma, the majority displayed indices of persistent airflow limitation and eosinophilic inflammation despite high-dose corticosteroids, suggesting potential for eosinophil-targeted biotherapies.

Dans un contexte social en mutation prônant l’autonomie de l’individu, le passage à l’âge adulte pour les jeunes en situation de vulnérabilité économique sociale et relationnelle se révèle un véritable défi. L’objectif de l’étude est de comprendre les ressources et les conduites adaptatives de ces jeunes leur permettant de faire face à la souffrance psychique que génère la discontinuité des liens, et d’éviter la désaffiliation sociale et l’errance. Cette recherche clinique de terrain s’inscrit dans une approche ethno-psychologique par sa méthode. Elle s’appuie sur les récits de 6 jeunes adultes âgés entre 19 et 25 ans rencontrés dans le cadre d’un hébergement temporaire en maison d’accueil. Chaque récit est séquencé et analysé selon plusieurs niveaux : les indicateurs sociologiques du passage à l’âge adulte, les modes de relations des individus au niveau familial et social, les indicateurs de précarité. Le parcours de ces jeunes adultes en situation de précarité sociale, cumulant vulnérabilité relationnelle et vulnérabilité économique, les amène à développer des conduites qui leur permettent à la fois de préserver le lien avec autrui, de s’adapter à l’environnement et de préserver une maîtrise d’une affiliation anxiogène. Leur vécu expérientiel de rupture et de perte continue à s’actualiser dans une nécessaire oscillation entre rapprochement et distanciation, en résonnance avec leur style d’attachement primaire. Conclusion « Etablir le lien sur un mode discontinu » apparait comme un mode d’adaptation à l’environnement à la fois protecteur de leur intégrité psychique et fragilisant leur socialisation.

Introduction : L’adolescence est une période tumultueuse caractérisée par des transformations d’ordre physique, psychologique, cognitive et sociale ainsi que par des conduites exploratoires et de recherche de sensations dans lesquelles la consommation de pornographie peut prendre part. L’exposition à la pornographie durant l’adolescence peut s’inscrire dans ce processus développemental avec le risque d’influencer les conduites sexuelles du jeune. Cette thématique peut, dès lors, susciter de nombreuses questions. Méthodologie : Notre recherche, réalisée sur une population d’adolescents âgé entre 15 et 19 ans (N=319), vise à analyser les conduites de consommation de pornographie (motivations, représentations et comportements) en lien avec la recherche de sensations, une dimension prégnante à l’adolescence. Plus particulièrement, nous avons analysé les motivations de ces jeunes à visionner des images et films à caractère pornographique et ce qui les amène à arrêter. Nous nous sommes, également, interrogés quant à l’influence de la consommation pornographique au niveau du développement psycho-sexuel et des pratiques sexuelles de ces jeunes. Pour ce faire, nous avons administré à ces jeunes un questionnaire comprenant, en plus des items se rapportant à la sexualité et la pornographie, plusieurs tests évaluant des dimensions du fonctionnement psychologique et social (test de solitude, recherche de sensation, relations aux pairs, délinquance auto-révélée,... ). Résultats : Nos résultats indiquent qu’une majorité des adolescents ont déjà visionné de la pornographie. L’intérêt pour ce média ainsi que son usage augmente avec l’âge, atteint son apogée vers 16-17 ans puis diminue. Cette tendance curvilinéaire se retrouve également dans les conduites exploratoires telles que les conduites déviantes et la recherche de sensations, ce qui nous amène à envisager une désistance spontanée de la consommation de pornographie en fin d’adolescence. Conclusions : Ces résultats montrent l’importance de comprendre la consommation de pornographie dans un processus développemental et nous amène à envisager une désistance spontanée de cette conduite en fin d’adolescence.

HD76431 is a slow rotating post-HB star that shows an underabundance of helium by 0.5 dex relative to the solar value. These observational facts suggest that atomic diffusion could be active in its atmosphere. We have used the MMT and Bok spectra to estimate the atmospheric parameters of the target star using the model atmospheres and synthetic spectra calculated with TLUSTY and SYNSPEC. The derived values of the effective temperature, surface gravity, helium abundance are consistent with those obtained by Ramspeck et al. (2001b). It appears that NLTE effect are not important for HD76431. We have used Stokes I spectra from ESPaDOnS at CFHT to perform an abundance analysis and a search for observational evidence of vertical stratification of the abundance of certain elements. The results of our abundance analysis are in good agreement with previously published data with respect to average abundances. Our numerical simulations show that carbon and nitrogen reveal signatures of vertical abundance stratification in the atmosphere of HD76431. It appears that the carbon abundance increases toward the deeper atmospheric layers. Nitrogen also shows a similar behaviour, but in deeper atmospheric layers we obtain a significant dispersion for the estimates of its abundance. To our knowledge, this is the first demonstration of vertical abundance stratification of metals in a post-HB star and up to now it is the hottest star to show such stratification features. We also report the detection of two SiIII and one TiIII emission lines in the spectra of HD76431 that were not detected in previous studies. [less ▲]

BACKGROUND: The objectives were to answer the following questions using a well-characterized population in Liege, Belgium: 1) what percentage of abdominal aortic aneurysm (AAA) patients have a positive family history for AAA, 2) what is the prevalence of AAAs among relatives of AAA patients; and 3) do familial and sporadic AAA cases differ in clinical characteristics. METHODS AND RESULTS: Unrelated AAA patients diagnosed at the Cardiovascular Surgery Department, University Hospital of Liege, Belgium, between 1999 and 2012 were invited to the study. A detailed family history was obtained in interviews and recorded using Progeny software. In the initial interview 62 (10%) of the 618 AAA patients reported a positive family history for AAA. We divided the 618 patients into two study groups: Group I: 296 AAA patients (268; 91% males) were followed up with computerized tomography combined with positron emission tomography, and Group II: 322 AAA patients (295; 92% males) whose families were invited to ultrasonography screening. Ultrasonography screening identified 24 new AAAs among 186 relatives (>/= 50 years) of 144 families yielding a prevalence of 13%. The highest prevalence (25%) was found among brothers. By combining the number of AAAs found by ultrasonography screening with those diagnosed previously the observed lifetime prevalence of AAA was estimated to be 32% in brothers. The familial AAA cases were more likely to have a ruptured AAA than the sporadic cases (8% vs. 2.4%; P<0.0001). CONCLUSIONS: The findings confirm previously found high prevalence of AAA among brothers, support genetic contribution to AAA pathogenesis and provide rationale for targeted screening of relatives of AAA patients.
