Malaria is a major public health problem in the Democratic Republic of Congo. Despite progress achieved over the past decade in the fight against malaria, further efforts have to be done such as in the surveillance and the containment of Plasmodium falciparum resistant strains. We investigated resistance to artemisinin-based combination therapies currently in use in Democratic Republic of Congo by surveying molecular polymorphisms in three genes: pfcrt, pfmdr1 and pfk13 to explore possible emergence of amodiaquine, lumefantrine or artemisinin resistance in Democratic Republic of Congo. This study essentially revealed that resistance to chloroquine is still decreasing while polymorphism related to amodiaquine resistance seems to be not present in Democratic Republic of Congo, that three samples, located in the east of the country, harbor Pfmdr1 amplification and that none of the mutations found in South-East Asia correlated with artemisinine resistance have been found in Democratic Republic of Congo. But new mutations have been identified, especially the M476K, occurred in the same position that the M476I previously identified in the F32-ART strain, strongly resistant to artemisinine. Antimalarial first-line treatments currently in use in Democratic Republic of Congo are not associated with emergence of molecular markers of resistance. [less ▲]

Au cours des quatre dernières années, l’Institut de Formation et de Recherche en Enseignement Supérieur (IFRES) et le Service Guidance Étude (SGE) de l’Université de Liège ont développé et mis en place un projet visant à promouvoir et optimiser les pratiques de feedback formatif et d’Assessment for Learning en première année. Le Projet Feedback a été initié en 2013 et poursuivi en 2014 au sein de la Faculté des Sciences appliquées, adapté depuis juin 2014 en Faculté de Droit, de Science Politique et de Criminologie, depuis 2015 en Faculté des Sciences, et depuis 2016 en Faculté d’Architecture. Le projet est mené dans un but de soutien à l’apprentissage et à la qualité de l’expérience vécue par les étudiants de première année. Il vise à engager un groupe d’enseignants en Architecture dans une réflexion portant sur leurs pratiques d’enseignement et d’évaluation, et de potentielles régulations à y apporter. Chacun des participants impliqués est porté à réenvisager certaines dimensions de son enseignement de première année à la lumière des théories se rapportant aux pratiques de feedback lors d’entretiens individuels structurés, avec l’équipe pédagogique encadrante (une référente pédagogique et une architecte), mais également lors de séances plénières collectives. Des initiatives, telles que des tests de prérequis en mathématique, ou une grille de critères pour le dessin ou encore outil réflexif d’aide à la prise de note en atelier de projet, ont été développées dans divers cours (Mathématique ; Théorie de l’Architecture ; Construction et d’Applications Constructives ; Atelier de Projet ; etc.). Parmi la quinzaine d’initiatives élaborées, certaines ont déjà été mises en œuvre, d’autres sont toujours en développement actuellement ou sont en phase de réflexion. L’avis des étudiants est au cœur des préoccupations du Projet Feedback. Plusieurs questionnaires ont été administrés aux étudiants, afin d’investiguer leurs perceptions relatives à diverses initiatives mises en place lors de l’année académique 2016-2017. [less ▲]

Recent efforts aim at assessing the fire performance of structures in a probabilistic framework. But there is still no well-established method to quantify the reliability of entire buildings. Previous works focused on isolated structural members, therefore not allowing for a determination of the global safety level of buildings. Here, a new methodology is developed to quantify the reliability of buildings in fire. The methodology uses Monte Carlo simulations for constructing fragility functions associated with different fire breakout locations in a building, then combines the functions to characterize the overall building conditional probability of failure, and finally incorporates the probabilistic models for intensity measure and fire occurrence likelihood. The methodology is applied to multi-story steel buildings. This work addresses fire reliability at the building scale, and therefore is useful for standardizing safety level as well as for evaluating community resilience. [less ▲]

Agriculture and aquaculture systems are used by many farmers in various tropical countries of Asia, America and Africa. They have proven their relevancy to increase the productivity of farms by optimising nutrient fluxes and reducing requirements for external fertilisers. This article analysed the current state of fish farming and the way it is integrated with other farm subsystems in the urban/peri-urban and rural areas of Kinshasa, Democratic Republic of Congo. More precisely, it examined the allocation of resources at the farm level, the recovery of helophytes plants, and the fate of fish production choices and it explored the possibility of intensifying these existing integrated farming systems. After a census of ponds in the urban and rural areas of Kinshasa, an on-site survey was conducted on 150 fish pond farms to assess the different activities practiced on farms, the impact of integrating crops and livestock to fish pond aquaculture and the constraints of the system. A total of three thousand and twenty (3020) fish ponds were recorded in the urban and rural areas of Kinshasa. Among these farms integrated aquaculture-agriculture systems exist with a wide diversity of practices (about 79% of farms combined fish with livestock and/or vegetable production). No striking differences between fish farms according to the allocation of resources, fish production method such as monoculture or polyculture, the recovery of helophytes plants and the fate of fish production choice were found depending on the location. However, fish farms were differently managed when combined with agriculture and/or livestock. Regarding the integration of the different subsystems through nutrient fluxes, 11 different movements of material between subsystems were found in integrated farms. However, not all fluxes are equally used in all farms and therefore improvements cannot be generalised. Improvements to be explored are such as making better use of manure pond mud and helophyte plants. For this purpose, proper training of farmers might be critical. Finally, bringing farmers together in cooperatives could also contribute to reduce the cost of purchase and transportation of fish fry and feed. [less ▲]

Currently, silvoarable agroforestry is receiving renewed interest in Europe, as a land use system that allows for combining the production of commodities with a range of non-commodity outputs, such as environmental protection. Despite the potential of this practice, it remains rarely implemented in Northwestern Europe. One of the obstacles in the adoption of silvoarable agroforestry systems is the lack of quantitative knowledge on the long term performance of different crops when they are competing for resources with trees. In the face of a wide range of possibilities, it remains difficult to obtain a clear overview of overall system functioning. In this thesis, we simplify this complexity by focusing our research questions on the resource of light, based on the assumption that in Belgian climatic conditions light is likely to be the predominant constraint for understorey crops in a silvoarable agroforestry system. With regard to this resource, we develop our research in order to gain insights into the growth mechanisms and final yield of shaded winter wheat and sugar beet crops. We address these questions using an artificial shade system, which has been developed to reproduce the effect of the heterogeneous spatio-temporal pattern of light observed under late-flushing trees in an agroforestry system, isolated from the competition effects for water and nutrients. The shade structures recreate two shade environments: continuous and periodic. The continuous shade treatment leads to shade throughout the entire day, while the periodic shade treatment induces an intermittent shade period, which varies during the day and according to structure orientation. Winter wheat responded to the late application of both shade treatments with a significant decrease in grain yield, which was partly compensated for by an increase in grain protein content. When shaded, sugar beet compensated through morphological adaptations of the aboveground part of the plant, and by a decrease in the final root dry matter and sugar yield. Overall, for both crops, the magnitude of the final yield repercussion varied with the level and period of shade application. Additionally, an arable plot bordered by a row of poplar trees was selected to evaluate the effect of real trees on the winter wheat. The reduction in the final grain yield follows a gradient, from underneath the trees to the centre of the field. Notwithstanding that interactions other than light competition may have occurred, the maximum yield reduction observed under the trees never reaches the level of decrease which is observed under the continuous shade treatment simulated by the artificial shade arrangement. This experimental approach with winter wheat was complemented by a modelling study, in which we evaluate the ability of the STICS crop model to simulate crops growing under dynamic shade. The results highlight the limits of the STICS model when it is used to simulate crop growth under contrasted shade conditions. Finally, we propose agroecology as a conceptual framework for developing sustainable and profitable agroforestry systems in Europe, and reflect on agricultural practices, food systems, and research methodologies.

My contribution aims to explain how a platform of electronic publishing such as OpenEdition might reach a larger public outside the academic sphere, and contribute to the revealing of research in the Humanities to civil society. Practices of academic blogging have expanded since the 2000's. Its potential as a vulgarization tool was acknowledged early. However, most initiatives in scientific blogging are concerned with the field of STM (Science, Technology, and Medicine). A quick overview of the classical literature about vulgarization shows that a great deal of attention is being paid to STM. As such, I propose to examine what the practices of communication are towards civil society in Humanities through Hypothèses, the blogging platform of OpenEdition. [less ▲]

Vista desde Europa, la historieta argentina aparece como un campo de experimentación. La obra de José Muñoz y Carlos Sampayo en particular se destaca por la radicalidad del diseño gráfico y de la construcción narrativa. Sin embargo, tiene sus raíces en producciones con vocación popular. Muñoz y Sampayo deconstruyen poco a poco las normas de la historieta de género basada en la primacía de la intriga y la ilusión de la realidad. Introduciendo numerosos aportes exógenos, el contenido ficcional resuena con la actualidad del momento y con el camino de vida de los autores. Muñoz y Sampayo substituyen la lectura clásica basada en el consumo del relato, con una lectura emocional. [less ▲]
