Cette communication propose de revenir sur nos résultats de terrain s’intéressant à l’évolution d’un acteur singulier de la politique de coopération belge au développement : le Service de l’Évaluation Spéciale (SES). Il s’agit d’un service d’évaluation de la politique fédérale de coopération belge au développement, créé à la suite d’une crise politique majeure à la fin des année 1990 en Belgique. À sa création en 2003, le SES est chargé d’évaluer toutes les activités relatives aux politiques de coopération au développement, et de rendre compte au Parlement fédéral belge à propos des conclusions et recommandations issues des évaluations. Mais, le Service a rencontré de nombreuses difficultés opérationnelles, budgétaires, internes et externes, voyant sa légitimité remise en cause. En 2013, l’ancien chef de service voit la fin de son mandat arriver et avec elle la fin (presque) certaine du SES. En 2014, une nouvelle alliance politique est au pouvoir en Belgique et un nouveau ministre est en charge de la coopération au développement. Il entreprend une réforme et le SES se voit attribuer de nouvelles compétences, davantage stratégiques. Il est désormais chargé, en plus de ces missions passées, de conseiller l’administration et le ministre ; de certifier, d’évaluer et d’harmoniser les systèmes de suivi et d’évaluation de l’ensemble des acteurs de la coopération belge. Un nouveau chef de service a été nommé et le SES doit faire face à de nouveaux défis : méthodologique, thématiques, opérationnels, en termes de vision, ou encore en ce qui concerne sa communication interne et externe.

BRAIN-TRAINS is a project supported by the Belgian Federal Government that deals with the possible development of rail freight intermodality in Belgium, analysing the current situation of the intermodal freight transport from an interdisciplinary perspective. Life Cycle Assessment (LCA) methodology has been chosen to analyse the environmental impact of freight transport in Belgium. In a first stage we have carried out the LCA of rail freight transport, inland waterways transport and road freight transport independently. The purpose of this paper is to discuss the first results obtained from the study of the environmental impacts of inland freight transport using the LCA methodology. [less ▲]

RTIs managements are quite diverse. Research efforts are thus needed in the areas of RTI acquisition; warehouse layout, inventory routing problem; production planning and control; tracking and scheduling. In this paper, the inventory-routing problem for the management of RTIs developed in Iassinovskaia et al. (2017) has been enriched by adding constraints referring to specificities that can be encountered in real life, such as minimum threshold or a maximum ceiling of RTIs to be returned or durability. Durability can be characterized by the number of times an RTI can be used which is called maximum number of lives n. For instances, glass bottle can be used 25 times, wooden pallet 50 times and Crates for bottles 120 times (Geyer et al., 2007). [less ▲]

This paper presents experimental results of a residential air source heat pump using a scroll compressor with variable speed and vapor injection. The system is modeled using the Modelica language and a comparison with the experimental results is performed. It was shown that there is still room for improvement on the control of the system. In fact, the tested gain scheduled PID controller showed limitation to maintain a low and steady superheat on both the suction and injection lines due to dynamics associated to the vapor split line or heat exchangers. The presented model of the system could be used in order to develop model based control and increase the system performances. [less ▲]

During the first year post-surgery, bacterial and fungal infections are the main causes of death in lung transplant recipients. Contributing substantially to the high mortality rate (35%) is the lengthy time-to-diagnosis, which includes both pathogen identification and antibiotic resistance profiling. A novel diagnostic strategy based on the detection of volatile compounds in breath seems a promising option to improve these patients’ outcomes. In order to demonstrate the feasibility of this approach, we characterized the volatile fraction of different clinical matrices (i.e., bronchoalveolar lavage (BAL) and blind bronchial aspirate (BBA)). Due to the complexity of the mixture and high dynamic range of the concentrations, we applied headspace solid phase microextraction (HS-SPME) combined with comprehensive two-dimensional gas chromatography coupled to time-of-flight mass spectrometry (GC×GC-TOFMS) to obtain a comprehensive overview of the sample headspace composition. Following the analytical step, we applied various univariate and multivariate statistical methods (e.g. random forest, principal component analysis, and hierarchical cluster analysis) in order to extract required information from the data. Based on the composition of the volatile fraction, we were able to differentiate between BAL and BBA with a classification accuracy of 88.4 %. Furthermore, we could correctly distinguish between individuals with active respiratory infections and those without infection with a 72.2 % classification accuracy. In some cases, it was also possible to differentiate between pathogens at the species level. These results are preliminary evidence to suggest the possibility of detecting infections in these patient without the use of time-consuming culture techniques. [less ▲]

Co-creating service recovery with customers has recently appeared as a new perspective in service research. Prior research demonstrates the effectiveness of co-created recovery strategies in driving customer outcomes, and out- lines when co-creating a service recovery is recommended. This paper complements prior research not only by demonstrating the mediating role of outcome favorability in the relationship between co-created service recov- ery and customer outcomes, but also by showing whether organizations with different levels of brand equity benefit equally from co-creating service recovery with their customers. The results of two experiments show that co-creating a service recovery makes customers believe they received the most favorable solution for the ser- vice failure, which in turn influences satisfaction with service recovery and repurchase intentions. In addition, co- creating a service recovery is recommended for organizations with low levels of brand equity, but not for orga- nizations with high levels of brand equity. [less ▲]

Animal toxins are peptides that often bind with remarkable affinity and selectivity to membrane receptors such as nicotinic acetylcholine receptors (nAChRs). The latter are, for example, targeted by α-conotoxins, a family of peptide toxins produced by venomous cone snails. nAChRs are implicated in numerous physiological processes explaining why the design of new pharmacological tools and the discovery of potential innovative drugs targeting these receptor channels appear so important. This work describes a methodology developed to discover new ligands of nAChRs from complex mixtures of peptides. The methodology was set up by the incubation of Torpedo marmorata electrocyte membranes rich in nAChRs with BSA tryptic digests (>100 peptides) doped by small amounts of known nAChRs ligands (α-conotoxins). Peptides that bind to the receptors were purified and analyzed by MALDI-TOF/TOF mass spectrometry which revealed an enrichment of α-conotoxins in membrane-containing fractions. This result exhibits the binding of α-conotoxins to nAChRs. Negative controls were performed to demonstrate the specificity of the binding. The usefulness and the power of the methodology were also investigated for a discovery issue. The workflow was then applied to the screening of Conus ermineus crude venom, aiming at characterizing new nAChRs ligands from this venom, which has not been extensively investigated to date. The methodology validated our experiments by allowing us to bind two α-conotoxins (α-EI and α-EIIA) which have already been described as nAChRs ligands. Moreover, a new conotoxin, never described to date, was also captured, identified and sequenced from this venom. Classical pharmacology tests by radioligand binding using a synthetic homologue of the toxin confirm the activity of the new peptide, called α-EIIB. The Ki value of this peptide for Torpedo nicotinic receptors was measured at 2.2 ± 0.7 nM. [less ▲]

GPR101 is an orphan G-protein coupled receptor with unknown ligand. In 2014, an international study clearly pointed to a strong association between this receptor and the X-linked acrogigantism (X-LAG) syndrome, which begins in childhood and causes the “tallest giants”. The children (carriers of the GPR101 duplication on the X chromosome) grow abnormally even before they are one year old, secrete phenomenal quantities of growth hormone, and develop pituitary adenomas that do not respond to current therapies. The mechanism by which GPR101 contributes to increased growth hormone secretion is currently not known. Nevertheless, the lack of mechanistic insight into the function of GPR101 precludes its validation as a drug target. This lack of knowledge on GPR101 is the consequence of the paucity of specific pharmacological/research tools currently available. Therefore, we propose to study GPR101 functions and its role in growth hormone regulation. First, we determined the receptor cellular localization. We also deciphered its constitutive signalling pathways by detecting high cAMP levels. We completed our study with an examination of receptor coupling to other pathways and G proteins. Furthermore, we applied targeted mutagenesis to modulate the receptor constitutive activity in order to understand the receptor function at a molecular level. These GPR101 mutants will help us to understand the role of this receptor in GH regulation and/or to treat people suffering from pituitary dysfunction. This information is an absolute prerequisite to link molecular pharmacology of GPR101 with physiological functions. [less ▲]

Traditional distribution channels that cover nanostores still abound in merging megacities. These traditional retail formats need to be visited and supplied very frequently (High Frequency Stores) which turns to be costly and time consuming if not well optimized. Supplying High Frequency Stores in emerging countries involves different constraints that make the associated optimization problems complex. In this paper, we deal with a real-life application problem where a company try to build an effective strategy to cover and to supply nanostores. We present an altered approach to a multi-depot multiple traveling salesman problem. The problem of concern is modeled as an assignment problem, combined with side constraints regarding disruption of pre-assignments and profit potential balance. The results show that the multi-objective function produces better profit and workload balance than setting a simple objective function and a constraint, one for the profit balance and the other for workload balance and vice-versa.

In this paper, the Fleet Size and Mix Vehicle Routing Problem (FSM) with sequence-based pallet loading and axle weight constraints is introduced. The effect of the integration of axle weight constraints in a FSM is analyzed by comparing the FSM with and without axle weight constraints. A vehicle fleet of 30-foot and 45-foot trucks, consisting of a tractor and a semi-trailer, is considered. Furthermore, two scenarios are analyzed for which the objective function differs: in the first scenario the objective is to minimize total distance while in the second scenario the objective is the minimization of total transport costs. An Iterated Local Search metaheuristic algorithm is used to tackle the problem. The results indicate that the vehicle fleet strongly influences the impact of the integration of axle weight constraints on solution cost. Furthermore, the analysis points out that fleet size and mix decisions may be influenced by the integration of axle weight constraints. [less ▲]
