Dry galloping of stays in cable-stayed bridges is a phenomenon that is still of interest to the scientific community. Over the course of the current three-year research project numerous experiments will be carried out to investigate the effect of turbulence and inclination angle on dry galloping. The novel aspect of this study consists of an in-depth investigation into the effect of non uniformity of the pipe surrounding the stay cables on the dry galloping excitation mechanism. Previous studies reported that dry galloping is caused by the appearance of a negative pressure bubble on one side of the circular cylinder at the critical Reynolds number range, leading to a rapid drop in the drag coefficient and the appearance of a non negligible lift force. This paper presents results from initial experiments in the wind tunnel at CSTB – Nantes, France. [less ▲]

The Brabant sablo-limoneux region is located in the south and near Brussels, in the phytogeographic district of Brabant (Atlantic domain). This region is characterized by a high diversity of local ecological conditions due to the alternance of important tertiary sand outcrops and quaternary silty layers. The agro-sylvo-pastoral activities, which were practiced on these sandy and sand-silty soils for centuries, caused the evolution of the climactic forest into semi-natural habitats such as dry heathland, sandy grassland and grassheath. The evolution of the heathland distribution from 1770 to the present has been studied on the scale of the Dyle hydrographic subbasin (43.000 ha). It is characterized by an important regression of this habitat in the study area (from 1460 ha in 1770 to 72 ha in 2006), mainly due to Pinus sylvestris orchards, and more recently, to urbanisation caused by the proximity of Brussels. A generalized ageing and an environmental closing characterize the evolution of heathland physiognomy since the middle of the 20th century. The phytosociology of heathlands, sandy grasslands and grassheaths has been characterized and 19 groups of vegetation have been differentiated. Among the 393 listed higher plant species, more than 30 are of great conservation interest in the regional context. A hierarchisation of restoration priorities has been established on the scale of the studied hydrographic subbasin and management measures have been proposed. [less ▲]

Konkombouri Hunting Zone is part of the transfrontier W–Arly–Pendjari ecosystem. Monthly dry-season records from wildlife monitoring show that the free-ranging elephant population increased from month to month with the progression of the dry season and the reduction of water points that still contained water. However, with the arrival of the first important rains, elephant density continued to increase because water and new shoots were available everywhere. In 2005 and 2006 elephant density in the Konkombouri Hunting Zone reached the highest mean dry-season elephant density recorded in West Africa in recent decades. This situation increases the impact on habitat close to water points and heightens human–elephant conflicts. [less ▲]

In order to explore the mechanism of the drying process and to optimize the drying operation, the comparative test was conducted with hot air drying and super-heated steam drying for lignite. The results showed that the steam condensation happened obviously in the initial stage of the super-heated steam drying, which resulting the obvious different drying kinetics compared to the hot air drying. The effect of the steam condensation on the initial stage of the drying process was studied through theoretical analysis of drying kinetics of super-heated steam drying. The mathematical model of super-heated steam drying was improved by combining the steam condensation on the basis of the mathematical model of the hot air drying. The experimental results verified that the fitting precision of the improved mathematical model was well and the determination coefficient was above 0.97. The study can provide a basis for optimizing the design and operating conditions of the drying equipment. [less ▲]

Near a small city of the Belgian ‘Ardennes’ (East of Belgium), modification of a natural slope for extension of industrial activities has required an extensive drainage in a weathered zone composed of colluvium and weathered claystones and quartzites. After a few days, the drain at the foot of the artificial slope was producing about 1000 m3/day while a natural spring located at a 200 m distance on the hillside was completely dried up. This spring was used for drinking water by the local community. A shallow geophysical prospection by refraction seismics and 2D geoelectrical tomography, associated to geological, morphostructural and hydrogeological observations have lead to a clear understanding of (1) the spring occurrence; (2) the feeding conditions of the spring and consequently (3) the ‘lateral’ hydraulic impact of the drain. In the hill, the bedrock is changing from quartzites (uphill) to claystones (downhill) inducing changes in hydraulic conductivity and thickness of the overlying weathered zone. On the basis of these hydrogeological conditions, associated to the specific topographic conditions, different possible remediation schemas have been proposed to the decision makers. Unfortunately, the full restoration of the natural spring appears to be one of the most technically and financially difficult option …while it is surely the most suitable in the name of a sustainable development.

A new generation of widely distributed systems to measure the Internet topology at the interface level is currently being deployed. Cooperation between monitors in these systems is required in order to avoid over-consumption of network resources. This paper proposes an architecture for a distributed topology measurement (DTM) system that, for the first time, decentralizes probing information. The key idea of our proposal is that, by utilizing a shared database as a communication method among monitors and taking advantage of the characteristics of the Doubletree algorithm, we can get rid of a specific control point, and a DTM system can be constructed in a decentralized manner. In this paper, we describe our implementation of a DTM, called Decentralized Tracing System (DTS). Decentralization within DTS is achieved using various distributed hash tables (DHTs), each one being dedicated to a particular plane (i.e., control or data). We also provide preliminary evaluation results. [less ▲]

Comme son titre le suggère déjà, le dernier roman de l’auteur bengali-américain Jhumpa Lahiri, The Lowland (« La Basse Terre »), traite moins de la vie d’hommes et de femmes qu’il ne parle d’espace et de géographie, et plus particulièrement, de la façon dont certains paysages peuvent se substituer à l’Histoire, quand cette dernière n’arrive plus à ‘porter’ ses zones d’ombre, ses propres impensés. Comme son titre ne l’indique pas, cette fois, The Lowland prend pour sujet les répercussions de l’Indépendance indienne, à Calcutta et au-delà, à travers les destinées entrecroisées de deux frères, Udayan et Subhash – le premier qui embrasse la révolution armée d’obédience maoïste et la cause des Naxalites, avec des conséquences dramatiques, le deuxième qui choisit de s’exiler aux Etats-Unis pour ses études, moins par ambition personnelle ou en raison de la grande instabilité politique de Calcutta dans les années 60 et 70, d’ailleurs, que pour enfin se donner le droit de rivaliser d’audace avec son frère cadet. Si j’ai choisi The Lowland pour aborder le sujet des enjeux esthétiques et spirituels de la commémoration, c’est justement parce que dans le dernier roman de Lahiri (paru en septembre 2013 et non encore traduit en français), la thématique historique est omniprésente, bien qu’elle reste en sourdine, perpétuellement soumise à une esthétique du détour, du déplacement, et du non-dit, qui trouvera son apogée (et, pour Subhash, une certaine forme de rédemption spirituelle) dans ce que l’on pourrait appeler l’émergence d’une topographie transnationale – et bien plus, transrégionale – de l’impensé historique.
