En résumé, l’application web REDI permet d’utiliser un cadre de référence uniforme tout en calculant un budget adapté au bénéficiaire. En outre, cet outil peut être un guide pour obtenir un aperçu des dépenses et revenus de la personne et a prouvé sa valeur éducative dans le cadre d’accompagnements individuels des clients. REDI peut contribuer à une plus grande prise de conscience sur le besoin d’uniformité existant au sein des CPAS auprès des assistants sociaux et des conseillers pour l’octroi de soutien financier supplémentaire. En outre, l’utilisation des budgets de référence contribue à ce que les assistants sociaux et conseillers comprennent mieux ce qui est nécessaire pour vivre dans la dignité, et participer pleinement à la vie en société. Espérons que sur le long terme, cela puisse modifier les politiques d’aide sociale et permettre une société plus inclusive. [less ▲]

In this paper, I argue that writing in English – for non-native – can be eased by the use of templates. Templates are pre-formatted and reusable models prepared by the author following proper publications according to the purpose of the writing. The use of templates offers at least three advantages: first, easing the writing since it follows a pre-formatted model; second, giving to the text a more English touch; third, increasing the chances of publication since it follows models which have been published. This technique works particularly well for short texts (for instance, abstracts, short papers or book reviews). Yet, templates are only a tool amongst other and should be used with these tools. Furthermore, they limit one’s creativity and enclose the author in a pre-formatted structure. Above all, to some extent, templates reflect the way of thinking and writing shared by the Anglo-Saxon academia. [less ▲]

A significant part of the collection of mid- and Late Cretaceous (Cenomanian, Campanian and Maastrichtian) gastropods, bivalves and worms described and/or illustrated by de Ryckholt in his seminal work Mélanges paléontologiques between 1854 and 1862, has recently been retraced in the historical collections at Liège University. Of the original collection, more than 206 specimens, including 196 nominal types (lectotypes and genotypes), all considered lost, are now available. The genotypes of the gastropod genera Tudicula de Ryckholt, 1862a and Prosopostoma de Ryckholt, 1862a are photographically illustrated for the first time. Prosopostoma bucculans, from the Cenomanian Bernissart Formation (formerly ‘Tourtia de Tournai’), is here chosen as the type species of the genus Prosopostoma, a possible stromboid. We also reassess the stratigraphic age of the type localities under the revised stratigraphic framework of Belgium and a detailed account on the research history of this material, in order to provide a thorough scientific background for future study of this formidable collection.

This paper deals with some essential open questions in the field of optimal power flow (OPF) computations, namely: the limitation of the number of controls allowed to move, the trade-off between the objective function and the number of controls allowed to move, the computation of the minimum number of control actions needed to satisfy constraints, and the determination of the sequence of control actions to be taken by the system operator in order to achieve its operation goal. To address these questions, we propose approaches which rely on the computation of sensitivities of the objective function and inequality constraints with respect to control actions. We thus determine a subset of controls allowed to move in the OPF, by solving a sensitivity-based mixed integer linear programming (MILP) problem. We study the performances of these approaches on three test systems (of 60, 118, and 618 buses) and by considering three different OPF problems important for a system operator in emergency and/or in normal states, namely the removal of thermal congestions, the removal of bus voltage limits violation, and the reduction of the active power losses.

Prussian blue, a mixed valence pigment, typically KFeIII[FeII(CN)6].xH2O, was the most widely used blue artistic pigment from ca. 1720 to the 1970's but, unfortunately, its paint layers, especially when used in conjunction with a white pigment, tend to fade or turn green upon extended exposure to light. In order to identify the mechanism underlying these changes, paint layers have been prepared with differing amounts of these white pigments and subjected to accelerated light exposure fading. The resulting unfaded and faded paint layers as well as both the Berlin white pigment, Fe2II[FeII(CN)6], and the partially oxidized Berlin green pigment, {KFeIII[FeII(CN)6]}x{FeIII[FeIII(CN)6]}1–x, have been characterized by Raman and iron-57 Mössbauer spectroscopy. The results indicate that, upon fading, the Prussian blue pigment painted with a linseed oil binder and (PbCO3)2Pb(OH)2 or ZnO, and to a lesser extent with TiO2, undergoes a reduction at the exposed paint surface and an oxidation in the bulk of the paint layer. This combined reduction and oxidation disrupts, at least in part, the FeIII–N–C–FeII intervalent electron transfer pathways in Prussian blue thus leading to pigment fading through a reduction in the intervalent electron transfer absorbance at about 700 nm.

The transcription factor NF-kappaB controls the expression of hundreds of genes involved in the regulation of the immune/inflammatory response, development, and apoptosis. In resting cells, NF-kappaB proteins are sequestered in the cytoplasm through their tight association with IkappaB proteins. NF-kappaB activation relies on the signal-induced IkappaB phosphorylation and degradation, thereby allowing the nuclear translocation of NF-kappaB proteins. In the nucleus, several post-translational modifications of NF-kappaB and chromatin remodeling of target genes are mandatory for NF-kappaB DNA binding and full transcription. Since 1991, reactive oxygen species (ROS) have been implicated in NF-kappaB activation. ROS enhance the cytoplasmic signaling pathways leading to NF-kappaB nuclear translocation, but reduction/oxidation (redox) also controls several key steps in the nuclear phase of the NF-kappaB program, including chromatin remodeling, recruitment of co-activators, and DNA binding. Here we describe the redox regulation of NF-kappaB activity in the nucleus. [less ▲]

The skeletal muscle mitochondria contain two isoforms of uncoupling protein, UCP2 and mainly UCP3, which had been shown to be activated by free fatty acids and inhibited by purine nucleotides in reconstituted systems. On the contrary in isolated mitochondria, the protonophoretic action of muscle UCPs had failed to be demonstrated in the absence of superoxide production. We showed here for the first time that muscle UCPs were activated in state 3 respiration by linoleic acid and dissipated energy from oxidative phosphorylation by decreasing the ADP/O ratio. The efficiency of UCPs in mitochondrial uncoupling increased when the state 3 respiratory rate decreased. The inhibition of the linoleic acid-induced uncoupling by a purine nucleotide (GTP), was not observed in state 4 respiration, in uninhibited state 3 respiration, as well as in state 3 respiration inhibited by complex III inhibitors. On the contrary, the progressive inhibition of state 3 respiration by n -butyl malonate, which inhibits the uptake of succinate, led to a full inhibitory effect of GTP. Therefore, as the inhibitory effect of GTP was observed only when the reduced state of coenzyme Q was decreased, we propose that the coenzyme Q redox state could be a metabolic sensor that modulates the purine nucleotide inhibition of FFA-activated UCPs in muscle mitochondria.

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 ▲]

Light rays from a multiply imaged quasar usually sample different path lengths across the deflector. Extinction in the lensing galaxy may thus lead to a differential obscuration and reddening between the observed macro-lensed QSO images. These effects naturally depend on the precise shape of the extinction law and on the redshift of the lens. By means of numerical Monte-Carlo simulations, using a least-squares fitting method and assuming an extinction law similar to that observed in the Galaxy, we show how accurate photometric observations of multiply imaged quasars obtained in several spectral bands could lead to the estimate of the lens redshift, irrespective of the visibility of the deflector. Observational requirements necessary to apply this method to real cases are thoroughly discussed. If extinction laws turn out to be too different from galaxy to galaxy, we find out that more promising observations should consist in getting high signal-to-noise low resolution spectra of at least three distinct images of a lensed quasar, over a spectral range as wide as possible, from which it should be straightforward to extract the precise shape of the redshifted extinction law. Very high signal-to-noise, low spectral resolution, VLT observations of H 1413+117 and <ASTROBJ>MG 0414+0534</ASTROBJ> should enable one to derive such a redshifted extinction law. [less ▲]

Aims. We report on the redshift of the lensing galaxy and of the quasar QJ 0158-4325 and on the lens model of the system. Methods. A deep VLT/FORS2 spectrum and HST/NICMOS-F160W images are deconvolved. From the images we derive the light profile of the lensing galaxy and an accurate relative astrometry for the system. In addition we measure the flux ratio between the quasar images in the Mg II emission line to constrain the mass model. Results. From the spectrum we measure the redshift of the lensing galaxy (z = 0.317 +/- 0.001) and of the quasar (z = 1.294 +/- 0.008). Using the flux ratio in the lens model allows us to discard the SIE as a suitable approximation of the lens potential. On the contrary the truncated-PIEMD gives a good fit to the lens and leads to a time delay of Delta t(A-B) = -14.5 +/- 0.1 days, with H-0 = 73 km s(-1) Mpc(-1). Conclusions. Using the flux ratio to constrain the mass model favors the truncated-PIEMD over the SIE, while ignoring this constraint leaves the choice open. [less ▲]
