This article examines On Black Sisters’ Street (2009), the second novel by Nigerian-Belgian writer Chika Unigwe. After briefly outlining the pioneering role played by Unigwe’s “Afro-European” fiction in Belgium, the essay argues that the author’s latest book presents its heroines, four African prostitutes working in Antwerp, as individuals caught between two forces: on the one hand, the social and economic pressures that lead to their subjection and, on the other, their wish to satisfy their own aspirations, which relates to the expression of their subjectivity. The article attempts to demonstrate that Unigwe’s novel explores the tension between these poles in at least four different ways: first of all, by using cultural stereotypes in an original manner; secondly, by developing the themes of renaming, slavery and objectification to point to the characters’ exploitation; thirdly, by hinting at the potential role of storytelling in the restoration of the prostitutes’ identity; and finally, by suggesting that the women’s very quest for subjectivity sometimes inadvertently induces their subjection. The essay concludes that Unigwe’s subtle treatment of these issues emphasises the complexity both of the novel’s protagonists and of their relationship with each other. [less ▲]

Starting from the idea of Tsallis on non-extensive statistical mechanics and the q-entropy notion, we recall the Theil index Th and transform it into the Th-q index. Both indices can be used to map onto themselves any time series in a non linear way. We develop an application of the Th-q to the GDP evolution of 20 rich countries in the time interval [ 1950 - 2003] and search for a proof of globalization of their economies. First we calculate the distances between the "new" time series and to their mean, from which such data simple networks are constructed. We emphasize that it is useful to, and we do, take into account different time "parameters": (i) the moving average time window for the raw time series to calculate the Th-q index; (ii) the moving average time window for calculating the time series distances; (iii) a correlation time lag. This allows us to deduce optimal conditions to measure the features of the network, i. e. the appearance in 1970 of a globalization process in the economy of such countries and the present beginning of deviations. The q value hereby used is that which measures the overall data distribution and is equal to 1.8125. [less ▲]

Background: The aim of this work was to study the ability of two different wild type strains of the yeast Yarrowia lipolytica to grow on olive mill wastewater (OMW) and their potential to produce high-value products such as lipases. Factors that affect cellular growth and OMW degradation were studied, such as nitrogen supplementation, cells concentration and surfactant addition. Results: Both strains, W29 and IMUFRJ 50682, were able to grow in OMW with 19 g L-1 of COD and approximately 800 mg L-1 of total phenols concentration. The strain W29 presented the highest potential for extracellular lipase production in OMW medium. Lipase productivity was improved by the medium supplementation with ammonium sulphate up to 6 g L-1, leading to 80% of COD degradation and 70% of total phenols reduction. The surfactant Tween 80 enhanced cell growth and COD degradation, but had a negative effect on lipase activity. Conclusions: Y. lipolytica has a great potential for OMW valorisation by its use as culture medium for biomass and enzymes production. The operating conditions that favoured lipase production differ from the conditions that improve COD reduction. © 2008 Society of Chemical Industry. [less ▲]

This research compares the spatial pattern of services provided in hospitals just before the introduction of the moratorium stopping the growth of the hospital sector (1979) with the current situation (2008) by their relationship to urban hierarchy. The method used to analyze this relationship is the application of the statistic coefficient ϒ. This work shows that this relationship is significant for the two studied periods. However, the presence of a nearby faculty of medicine appears to interfere significantly on this relationship. The study also highlights a slight tendency to the strengthening of the aforementioned relationship. Besides, it demonstrates the existence of different spatial behaviours depending on the type of service. [less ▲]

We study irregularity properties of generic Peano functions: we apply these results to the determination of the pointwise smoothness of a Peano function introduced by Lebesgue and of some related functions, showing that they are either monoholder or multifractal functions. We test on these examples several numerical variants of the multifractal formalism, and we show how a change of topology on R can affect the Holder regularity of such functions.

The nucleosome ordering observed in vivo along yeast genes is described by a thermodynamical model of nonuniform fluid of 1D hard rods confined by two excluding energy barriers at gene extremities. For interbarrier distances L≲1.5  kbp, nucleosomes equilibrate into a crystal-like configuration with a nucleosome repeat length (NRL) L/n∼165  bp, where n is the number of regularly positioned nucleosomes. We also observe “bistable” genes with a fuzzy chromatin resulting from a statistical mixing of two crystal states, one with an expanded chromatin (NRL ∼L/n) and the other with a compact one (NRL ∼L/(n+1)). By means of single nucleosome switching, bistable genes may drastically alter their expression level as suggested by their higher transcriptional plasticity. These results enlighten the role of the intragenic chromatin on gene expression regulation. [less ▲]

We consider variations of the standard leptogenesis picture arising from the presence of an additional scale related to the breaking of a U(1)X abelian flavor symmetry. We show that quite generically the presence of an additional energy scale might introduce new qualitative and quantitative changes on leptogenesis. Especially interesting is the possibility of having succesful TeV leptogenesis with a vanishing total CP violating asymmetry. By solving the corresponding Boltzmann equations it is shown that these kind of scenarios encounters no difficulties in generating the cosmic baryon asymmetry. [less ▲]

Depuis une dizaine d’années, les apparitions massives de la méduse scyphozoaire Pelagia noctiluca (Forskål) sont de plus en plus fréquentes en Méditerranée Occidentale. Ces pullulations perturbent les activités récréatives, en causant des brûlures douloureuses aux baigneurs. Elles interfèrent avec la pêche, colmatent les filets et entrent en compétition avec les poissons pour la nourriture. Elles peuvent également tuer les poissons et leurs larves dans les enclos d’aquaculture, ou boucher les canalisations des centrales électriques et de dessalage. Ces pullulations constituent donc une nuisance pour les eaux de baignade et les installations aquacoles et hydrauliques côtières. Cependant, l’éradication ou simplement le contrôle des populations de méduses reste impossible à l’heure actuelle, car leur distribution est à large échelle et déborde largement du plateau continental. L eurs apparitions dans les eaux côtières sont généralement fortuites, discontinues dans le temps et dans l’espace et généralement sous forme d’essaims. Pour ces mêmes raisons, l’écologie des méduses, les causes des pullulations et leur impact sur la chaîne alimentaire sont mal connues et font l’objet d’interprétations contradictoires par les médias. Leur taxonomie, la multiplicité de leurs formes et de leurs cycles de développement restent imprécis. Grâce au soutien de l’Agence Française de l’Eau Rhône Méditerranée et Corse, de la communauté Française de Belgique (Programme RACE), du Fond Belge de la Recherche Scientifique (FRS-FNRS), de STARESO et de l’Université de Liège, une approche scientifique de la variabilité de la méduse scyphozoaire Pelagia noctiluca (Forskål) a été entreprise en Baie de Calvi (Corse) en relation avec et les changements environnement. Les objectifs principaux de cette action menée à la station STARESO sont de contribuer à comprendre et à prévoir les fluctuations d’abondance de cette espèce - clé en réponse aux variations de l’environnement, sur base d’observations de terrain et de la synthèse d’informations existantes. Elle a pour but de développer un schéma conceptuel et une base de données susceptibles d’intervenir comme outil prédictif des populations de méduses en Méditerranée Occidentale. Une synthèse de la littérature scientifique a porté sur la morphologie, la dangerosité, le cycle de reproduction et le développement de, sa nutrition et son métabolisme, sa distribution spatiale et temporelle et sur les méthodes d’investigation et de comptages. Des mesures hebdomadaires effectuées depuis 2003 à partir du quai de STARESO ont permis de montrer une augmentation graduelle de l‘abondance de la méduse Pelagia noctiluca de 2004 à 2005, suivie d’une augmentation dramatique en 2006, puis d’une diminution significative les étés 2007 et 2008. Ces mesures ont permis également d’aborder la formation des essaims et tenté d’expliquer les causes de leur accumulation le long des plages. [less ▲]

Through analysis and an attempt to assess the system developed at the level of the Wallonia-Europe Academy in the context of Center for Higher Didactics (Centre de Didactique Supérieure : CDS), the purpose of this article is to reflect on the specificities and constraints of a training limited to teachers in charge of First Generation students, those specificities being especially constraining since the CDS training sessions take place in a larger context : the training of all the university teachers. The Liege experience enlightens some determinant factors : sensitizing first on the interest of such a training, centring the training on close coaching of students learning with a focus on their difficulties or deficiencies and with help given to teachers in resolving them, meeting the diversity of the situations lived by those teachers (notably in terms of students number and disciplines), taking into account their expectations in accordance with their profile, cleverly combining oral speeches, testimonies and debates, suggesting a diversity of concrete intervention trails… By the way, the joined organization of introduction sessions and close coaching seminars seems to be a relevant formula in order to meet such kind of objectives.

The North Anatolian Fault (NAF) is a ~1500-km-long, arcuate, dextral strike-slip fault zone in northern Turkey that extends from the Karliova triple junction to the Aegean Sea. East of Bolu, the fault zone exhibits evidence of a sequence of large (Mw>7) earthquakes that occurred during the 20th century that displayed a migrating earthquake sequence from east to west. Prolonged human occupation in this region provides an extensive, but not exhaustive, historical record of large earthquakes prior to the 20th century that covers much of the last 2000 years. In this study, we extend our knowledge of rupture events in the region by evaluating the stratigraphy and chronology of sediments exposed in a paleoseismic trench across a splay of the NAF at Destek, ~6.5 km east of Lake Ladik (40.868°N, 36.121°E). The trenched fault strand forms an uphill-facing scarp and associated sediment trap below a small catchment. The trench exposed a narrow fault zone that has juxtaposed a sequence of weakly-defined paleosols interbedded with colluvium against highly-fractured bedrock. We mapped magnetic susceptibility variations on the trench walls and found evidence for multiple visually unrecognized colluvial wedges. This technique was also used to constrain a predominantly dip-slip style of displacement on this fault splay. Sediments exposed in the trench were dated using both charcoal and terrestrial gastropod shells to constrain the timing of the earthquake events. While the gastropod shells consistently yielded 14C-ages that were too old (by ~900 years), we obtained highly reliable 14C-ages from the charcoal by dating multiple components of the sample material. Our radiocarbon chronology constrains the timing of seven large earthquakes over the past 3000 years prior to the 1943 Ladik earthquake, including event ages (including 2 sigma error):1437-1788AD, 1034-1321AD, 549-719AD, 17-585AD (1-3 events), 351BC-28AD, 700-392BC, 912-596BC. Our results indicate an average inter-event time of 385±166yrs (1 sigma) [less ▲]
