Sinds 2001 zijn de Gewesten bevoegd voor de organisatie en verkiezing van lokale overheden. Ze hebben elk verschillende regels aangenomen. In hoeverre beïnvloeden die regels de onderhandelingen over een politieke meerderheid en de benoeming van burgemeesters in België? Om die vraag te beantwoorden werden semigestructureerde interviews afgenomen van verschillende burgemeesters en schepenen in gemeenten uit de drie Gewesten. Daaruit bleken niet enkel verschillen tussen maar ook binnen Gewesten. De bepalingen inzake benoemingswijze van de burgemeester zijn essentieel om inzicht te krijgen in de dynamiek van de politieke onderhandelingen. Dit artikel gaat dieper in op de banden tussen de juridische normen en het spel van de politieke actoren. [less ▲]

Conspicuous characters are often useful in species identification. Yet, identification and delineation are two different processes, and such characters do not necessarily provide the best basis on which species can be delineated. This is illustrated by the case of the Labeo with papillary lips from the Congo basin. Traditionally, species delineation in this group was based on a conspicuous trait: the shape of the dorsal fin, which shows a profound degree of differentiation. Morphometric analyses were performed on 185 specimens both with and without measurements taken on this fin. The groups obtained using these two approaches were compared with those obtained through DNA barcoding. For this, 24 sequences of the standard barcoding COI gene were obtained. Species delineations based on morphological and molecular results were in agreement when the shape of the dorsal fin was ignored. This suggested that of the five nominal species known from the Congo basin, L. altivelis, L. rosae, L. lineatus, L. weeksii and L. maleboensis, only the former three remain valid. Consequently, L. weeksii was synonymised with L. altivelis and L. maleboensis with L. lineatus. The sole Congo basin endemic is L. lineatus as L. altivelis and L. rosae also occur in more southern basins. The use of the shape of the dorsal fin in morphological studies has previously led to overestimates of species diversity in this group. This is due to the fact that L. altivelis shows a remarkable amount of geographical variation for this trait. The large amount of intra- and interspecific variation in this character was caused by differential allometric growth in different parts of the dorsal fin. [less ▲]

Cet article propose d’explorer la manière dont Judith Butler remobilise la thèse althussérienne de l’interpellation dans La Vie psychique du pouvoir . Nous essaierons de saisir les éléments qui nous paraissent enrichir la problématique althussérienne, suggérant que la compréhension de la dimension psychique du pouvoir qui ressort de sa lecture permet de complexifier la relation du sujet au pouvoir. Afin de tisser des liens précis entre l’interpellation chez Althusser et la subjectivation chez Butler, nous examinerons d’abord le rôle que Nietzsche et Foucault recouvrent dans la formulation de la théorie de la subjectivation chez Butler. Ensuite, il s’agit de comprendre en quoi la matérialité et l’ambiguïté des mécanismes de subjectivation, qui déjà caractérisent l’interpellation althussérienne, deviennent chez Butler les sources d’une relation critique aux conditions d’émergence du sujet. Enfin nous préciserons comment elle mobilise de telles sources pour élaborer cette figure de la psychanalyse qu’est la mélancolie et pour décrire sa transformation en deuil. [less ▲]

It is commonly accepted that the current society needs to partially substitute fossil resources by renewable ones. Among many solutions, one approach consists in the development of biorefinery involving lignocellulosic biomass to produce bio-based materials and fuels. This study focuses on the comprehension of an organosolv treatment designed to break the complex lignocellulosic structure for high purity lignin extraction from tall fescue (Festuca arundinacea Schreb.). This grass benefits from an increasing interest in Western Europe and has been suggested as feedstock for biorefinery. However, its use as material for high purity lignin production has not been determined yet. Ethanol/water, 92/8% [v/v] with H2SO4 0.32 M was investigated at pilot scale under conventional heating (5 °C min−1 during 30 min and stabilized at 148 °C for 5 min). Precipitated lignin were analyzed as well as the composition of side-stream products (recovered cellulosic pulp and the aqueous hydrolysate). Lignin has been recovered at a purity level of 90% with a yield of 60%. The main contaminants were nitrogen containing compounds and degraded hemicelluloses. 2D-HSQC NMR (Two Dimension-Heteronuclear Single Quantum Correlation Nuclear Magnetic Resonance) revealed a co-extraction of ferulates and coumarates function as well as arabinoxylan. Cellulose was recovered at 53% purity with 60% yield. The conditions appear to be too harsh for tall fescue and led to significant amount of cellulose degradation. A process using a lower alcohol concentration will be developed to provide better yields of both cellulose and lignin. [less ▲]

The competence-based approach is largely widespread in the nursing schools and is viewed as a golden standard for professional teaching. But the practical use of the concept is varying among institutions and even teachers. The goal of this narrative review is to clarify the conception of competence and its use in the fields of education and nursing. Regarding education, Gonczi, Tardif, Jonnaert and Beckers are the key authors referred to. A first apparent consensus over the holistic nature of the competence quickly gives place to the observation of important nuances in conceptions. Similarly, in the field of nursing, Benner is first discussed, and recent literature reviews and concept analyses are taken into account: similar nuances are detected, as well as difficulties in the practical implementation of the concept. Considering the lack of consensus and the paradigmaticalincoherences detected among the sources consulted for this review, we question the use of competence as single point of view for teaching and assessing, and we propose other avenues to be explored in order to recognize emergent professionality.

La culture d’amandier joue un rôle socio-économique important dans plusieurs zones rural du Maroc oriental. Le projet de Filière Amandier (*PROFAO) porte sur l’extension des surfaces plantées d’amandier avec création des nouveaux vergers et des nouvelles unités de concassage des amandes et de valorisation des dérivées d’amandes. En termes de profil variétal les principales variétés plantés dans le cadre du projet PROFAO sont Beldi (Be) Marcona (Mr), et Fournat (Fr) et l’association Ferragnes / Ferraduel (F/F). Le présent travail de recherche appliquée s’intéresse aux possibilités et moyens de valorisation en poste récolte des fruits d’amande et leurs dérivées (Huile d’amande et Tourteau) au niveau des coopératives de la région orientale du Maroc. La récolte des amandes se fait encore par Gaulage, par contre l’extraction des « amandons » de leurs coques, est facilitée par des machines de concassage. Les brisures issues du concassage sont valorisées sous forme d’huile d’amande. Les rendements en huile varient entre un minimum de 51% pour Be et un maximum de 56,6% pour l’association F/F. Le profil en acides gras (AG) se distingue par sa richesse en AG insaturés (principalement des deux AG: Oléique et Linoléique) et une teneur en AG saturés ne dépassant pas les 10%. Ces huiles de brisures d’amandes grâce à leurs teneurs en antioxydant naturels t (Tocophérols), et selon les tests au rancimat présentent de bons indices de stabilité oxydative (OSI) qui varient entre minimum pour l’huile Fr (OSIFr = 20h) et un maximum pour l’huile F/F (OSIF/F= 27h) [less ▲]

Salmonella enterica serotypes (Salmonella sp.) are the second cause of bacterial foodborne zoonoses in humans after campylobacteriosis. Pork is the third most important cause for outbreak-associated salmonellosis, and colibacillosis is the most important disease in piglets and swine. Attachment to host cells, translocation of effector proteins into host cells, invasion and replication in tissues are the vital virulence steps of these pathogens that help them to thrive in the intestinal environment and invade tissues. Feed contamination is an important source for Salmonella infection in pig production. Many on-farm feeding strategies intervene to avoid the introduction of pathogens onto the farm by contaminated feeds or to reduce infection pressure when pathogens are present. Among the latter, prebiotics could be effective at protecting against these enteric bacterial pathogens. Nowadays, a wide range of molecules can potentially serve as prebiotics. Here, we summarize the prevalence of Salmonella sp. and Escherichia coli in pigs, understanding of the mechanisms by which pathogens can cause disease, the feed related to pathogen contamination in pigs and detail the mechanisms on which prebiotics are likely to act in order to fulfil their protective action against these pathogens in pig production. Many different mechanisms involve the inhibition of Salmonella and E. coli by prebiotics such as coating the host surface, modulation of intestinal ecology, downregulating the expression of adhesin factors or virulence genes, reinforcing the host immune system.

A six-month-old alpaca was presented to the veterinary teaching hospital of the University of Liège (Belgium) with a bilateral cataract. A decision was made to perform bilateral cataract surgery after an ocular ultrasound and electroretinogram were performed to assess the posterior segment and retinal function, respectively. As a premedication, the alpaca received xylazine, butorphanol and midazolam intramuscularly. Anaesthesia was induced subsequently with ketamine and midazolam intravenously and maintained with isoflurane on oxygen/air mixture. The alpaca was mechanically ventilated during surgery. Neuromuscular blockade was induced and maintained with cis-atracurium intravenously. The dose of cis-atracurium was permanently adapted using a peripheral nerve stimulator. This case report brings new knowledge regarding the use and dosage of cis-atracurium in alpacas. [less ▲]

The $1/N_c$ expansion method for studying the mass spectrum of excited baryons is shortly reviewed together with applications to mixed symmetric states. The $[{\bf 70, \ell^+}]$ multiplet, belonging to the $N$ = 2 band, is reanalyzed, with emphasis on hyperons and the SU(3) symmetry breaking operators entering the mass formula to first order. An important result is that the hierarchy of masses as a function of strangeness is correctly reproduced for all multiplets. Predictions for unknown excited hyperons to SU(6) $\times$ O(3) multiplets are made. [less ▲]

Two techniques of extraction of essential oils (Steam distillation assisted by microwave (SDAM) and hydrodistillation assisted by microwave (HDAM)) are respectively advanced steam distillation (SD) and hydrodistillation techniques (HD), in which a microwave oven is used in the extraction process. They are considered as accelerated techniques extraction performed at atmospheric pressure. The cryogrinding (CG) showed a difference on the yields and aromatic profile comparing to the sample grinding. Isolation and concentration of volatile compounds are performed by a single stage for the extraction of volatile oil from Algerian (Sahara) Cuminum cyminum seeds (CCS). The chemical composition of the essential oil of this plant as a function of extraction time was also studied. The major components and family classes showed a significant variation with the extraction time. Gas chromatography (GC), GCxGC-mass spectrometry (GCxGC-MS)] were utilised for qualitative and quantitative analysis of essential oils extracted by these two methods. The major compounds are cumin aldehyde (HDAM-CG: 20.50-53.35 %, SDAM-CG: 21.68 66.6 %), p-cymene (HDAM-CG: 14.1-37.54 %, SDAM-CG: 6.06-20.18 %), β-pinene (HDAM-CG: 4.53-14.74 %, SDAM-CG: 4.3-32.65 %) and γ-terpinene (HDAM-CG: 1.26-14.70 %, SDAM-CG: 5.13-18.23 %).
