A cellulolytic consortium was isolated from a composting plant in order to boost the initial hydrolysis step encountered in anaerobic digestion. Improvement of the cellulose degradation, as well as biogas production, was observed for the cultures inoculated with the exogenous consortium. Metagenomics analyses pointed out a weak richness (related to the number of OTUs) of the exogenous consortium induced by the selective pressure (cellulose as sole carbon source) met during the initial isolation steps. Main microbial strains determined were strictly anaerobic and belong to the Clostridia class. During cellulose anaerobic degradation, pH drop induced a strong modification of the microbial population. Despite the fact that richness and evenness were very weak, the exogenous consortium was able to adapt and to maintain the cellulolytic degradation potential. This important result point out the fact that simplified microbial communities could be used in order to increase the robustness of mixed cultures involved in environmental biotechnology. [less ▲]

La présente étude se consacre à la réflexion sur la corrélation entre l’infrastructure routière et le développement socioéconomique. C’est en s’appuyant sur un ensemble très large de variables sociales et économiques jugées pertinentes que cette étude tente de contribuer à la construction d’un dispositif des variables aptes à saisir les changements entraînés par l’intervention du projet routier basée sur la technologie HIMO. Malgré quelques différences, la plupart des variables/indicateurs gardent les mêmes tendances évolutives dans ces différentes régions. Au-delà de notes de succès socioéconomique enregistré, des points d’attention subsistent et méritent des réflexions correctives dans une logique de poursuite et d’extension des activités de réhabilitation routière, notamment la persistance d’inégalités de genre dans les chances d’accès au travail, l’absence d’actions complémentaires devant appuyer les activités agropastorales et la persistance de la problématique de prise en charge de l’entretien du réseau réhabilité par les ressources tant locales, provinciales que nationales. L’étude repose essentiellement sur les données secondaires consignées dans les différents documents et rapports en les analysant dans une approche comparative avec les résultats obtenus par d’autres études réalisées en République Démocratique du Congo et dans d’autres régions en Afrique subsaharienne, dont particulièrement le Burkina Faso et le Bénin.

In this paper, we consider a regression model in which the tail of the conditional distribution of the response can be approximated by a Generalized Pareto distribution. Our model is based on a semiparametric single-index assumption on the conditional tail index; while no further assumption on the conditional scale parameter is made. The underlying dimension reduction assumption allows the procedure to be of prime interest in the case where the dimension of the covariates is high, in which case the purely nonparametric techniques fail while the purely parametric ones are too rough to correctly fit to the data. We derive asymptotic normality of the estimators that we define, and propose an iterative algorithm in order to perform their practical implementation. Our results are supported by some simulations and a practical application on a public database of operational losses. [less ▲]

BACKGROUND: Gait impairment seems to be a risk factor for falls and mortality. Because gait change cannot be determined easily with classical clinical tests, some authors have suggested that it might be useful to use a gait-analysis system among elderly community-dwelling people. OBJECTIVE: The main objective of the present study was to determine the predictive value of a quantitative evaluation of the gait characteristics in nursing home residents for the occurrence of falls and death performed using a tri-axial accelerometer (Locometrix(R)). MATERIAL AND METHODS: One hundred elderly nursing home residents (80 women and 20 men, mean age 86.4 +/- 6.04 years) were included in this study with the aim to follow them for 2 years. Deaths and falls were systematically recorded. A quantitative evaluation of a 10-second walk was performed with a tri-axial accelerometer (Locometrix(R)). Demographic data (i.e age, sex, body mass index) and clinical data (i.e. fall risk evaluated by the Tinetti test) were also recorded. RESULTS: During the two years of follow-up, 27 patients died. After adjustment on all potential confounding variables, only body mass index was significantly associated with the risk of mortality with an odds ratio of 0.86 (95% CI: 0.77-0.96, p=0.04). At the end of the study period, 440 falls had occurred (mean: 4.44 +/- 6.79 falls per patient) but no single factors were independently associated with fall incidence. CONCLUSION: Our results show that a quantitative gait analysis performed using a tri-axial accelerometer is not predictive of long-term falls and mortality among nursing home residents. [less ▲]

L’infrastructure des transports constitue l’un des piliers du développement africain. Car, en tant qu’activité transversale, le transport exerce une grande influence sur tous les domaines socio-économiques et est appelé à jouer un rôle primordial dans l’accélération de la croissance et la réduction de la pauvreté. Compte tenu des caractéristiques économiques et géographiques de l’Afrique et tenant compte de la protection de l’environnement, l’infrastructure ferroviaire constitue ainsi l’épine dorsale des activités économiques et sociales de ce continent. Fort malheureusement, à l’exception de quelques cas isolés, la quasi-totalité des réseaux ferroviaires africains ont accumulé d’importants retards dans leur modernisation. De plus, la qualité de gestion de ces compagnies est souvent mise en question. Eu égard à ce qui précède, cet ouvrage a pour principal objectif d’établir un état des lieux des chemins de fer africains. De ce fait, il contribue, sans nul doute, à une meilleure compréhension des mécanismes économiques et de gestion des entreprises ferroviaires africaines sur plusieurs aspects : nécessité économique du rail – cadre institutionnel – viabilité des réseaux.

This paper presents recent investigations in the field of lubricant escapes from asperities. This phenomenon, named Micro Plasto Hydrodynamic Lubrication (MPHL), induces friction variation during metal forming processes. A better understanding of MPH lubrication would lead to a better management of friction, which is a central element in most sheet metal forming processes. To fulfil that goal, experiments were conducted in plane strip drawing using a transparent upper tool in order to observe lubricant flow around macroscopic pyramidal cavities. These experiments were then numerically reproduced with two complementary Finite Element models. The numerical results are discussed in this paper and show good agreement with experimental measurements. [less ▲]

Nudge and the Law explores the legal implications of the emergent phenomenon of behaviourally informed intervention. It focuses on the challenges and opportunities it may offer to the policymaking of the European Union. This dual focus on law and on Europe characterises our endeavour. This volume has been structured by taking as a point of the departure the current nudging debate, which mainly comprises two strands of enquiry: when is it legitimate for States to use psychology to inform policy? (the legitimacy debate) and, to the extent that it is legitimate, how can behavioural insights in practice be incorporated into the decision making processes? (the practicability debate). Against this backdrop we brought together scholars who could analyse what behavioural insights might bring to EU law, both at a horizontal level and at a sectoral level. This volume endeavours to present the results of their research in a manner that is accessible both to EU law specialists who are not yet familiar with behavioural sciences and to behavioural lawyers who are not specialists in EU law.

This study aims to measure under barn conditions the emissions of NH3, N2O, CH4 and CO2 associated with gestating sows (trial 1) and fattening pigs (trial 2) fed either a control diet (CTD) based on cereals or a high-fibre diet (HFD) based on sugar beet pulp (SBP). Three successive batches of 10 Belgian Landrace gestating sows were used for trial 1. Two successive batches of 24 Pi etrain Belgian Landrace fattening pigs were used for trial 2. Animals were kept on slatted floor. The gas emissions were measured by infrared photoacoustic detection and expressed per day and per livestock unit, equals to 500 kg body weight. Similar trends were observed for both animal types. With HFD, the NH3 emissions were reduced (27.2 vs. 36.5 g for the gestating sows, P < 0.001; 23.2 vs. 45.0 g for the fattening pigs, P < 0.001) but the CH4 emissions were increased (41.5 vs. 21.0 g for gestating sows, P < 0.001; 37.9 vs. 27.2 g for fattening pigs, P < 0.001). The fibre content of the diet had not significant impact on N2O emissions (around 1.4 g for gestating sows and 2.1 g for fattening pigs, P > 0.05), and on CO2 emissions (around 6.0 kg for gestating sows and 9.1 kg for fattening pigs, P > 0.05). Most of manure parameters did not statistically differ regarding the treatment. Reproductive performance and body condition of the sows were not affected by the diet. However, growth performance and carcass traits of the HFD-fed fattening pigs were deteriorated compared to CTD. [less ▲]

In this chapter, we review the behavioural critique of EU consumer legislation and focus is on how behavioural insights are being incorporated or could realistically be incorporated in existing or new rules. Behavioural scholars sometimes present EU consumer law as archaic and counter-productive and this creates a diffuse view that a behavioural turn would constitute a revolution for EU consumer law. We do not subscribe to this view. We begin by putting the current legitimacy crisis of EU consumer law in perspective. Specifically, we explain why EU law evolved to be an apparent anti-model of behavioural regulation and discuss whether the internal market constraints that still exist prevent a behavioural turn. We conclude that they do not. We illustrate this claim in relation to disclosure mandates. The central feature of disclosure mandates in EU consumer law has been severely criticised in the light of behavioural findings. We agree that they are over-used but find that disclosure mandates, as a technique, can still serve a useful purpose and suggest how their use can be streamlined. We also point out that recent developments tend to make disclosures smarter and point to directions to pursue this evolution. Finally, we turn to the core message of behavioural insights to policy makers: ‘make it simple’ and analyse how it has been received in EU consumer law beyond the specific issue of disclosure. We find evidence of an intention to simplify which predates the current commitment of the Commission to make simplification a priority, but highlight that efforts to simplify have led to half-baked solutions that are not simple enough. We conclude that EU consumer law does not need a revolution but a continued reform and that it contains the seeds of a more behavioural approach. [less ▲]
