L’extension du réseau ferroviaire allemand dans l’Eifel au cours des années 1880-1890 a suscité très tôt les craintes des diplomates et des agents de renseignement français. Cette extension en soi, d’abord motivée par des intérêts économiques, n’aurait suscité aucun commentaire si elle n’avait été accompagnée de l’extension du réseau ferroviaire belge dans le Luxembourg. Ce développement des infrastructures ferroviaires s’inscrivait qui plus est dans un contexte explosif de tension entre la France et l’Allemagne : bellicisme du général Boulanger et incident Schnaebelé de 1887. De son côté, la Belgique ne contribuait pas peu à alimenter ces bruits de guerre puisque les Chambres belges votaient la même année les crédits nécessaires pour fortifier la ligne de la Meuse en vue d’en interdire l’usage à un quelconque belligérant. Certes, cette crise s’apaise rapidement sur le plan de la diplomatie officielle mais un climat de méfiance subsiste, qui transparaît à travers les articles de journaux ou les rapports secrets des attachés militaires. Dans ce contexte, le réseau ferroviaire belgo-allemand est sous étroite surveillance française. En 1893, la création du camp militaire d’Elsenborn à la lisière de la Belgique vient confirmer les appréhensions de ceux qui crient depuis plusieurs années à la violation prochaine de la neutralité belge par l’Allemagne. Selon l’historiographie française de l’entre-deux-guerres, Elsenborn aurait été constitué dans un seul et unique but : prendre la place forte de Liège par surprise pour se jeter ensuite sur la France. Ce fait semble confirmer par l’adoption future du plan Schlieffen. Mais n’est-ce pas là faire preuve d’un dangereux anachronisme ? Les documents récents ont en effet révélé qu’aucun changement stratégique majeur ne s’était opéré dans le plan allemand à cette époque. Cependant, un doute subsiste. Comment ne pas y voir au moins un début d’intérêt pour le territoire belge ? A la lumière des nouvelles infrastructures apparues à la frontière belgo-allemande, le passage par la Belgique devenait « techniquement » réalisable. C’est cet intérêt renouvelé pour le territoire belge dans les milieux diplomatiques et militaires que nous étudierons dans cet article…à la veille des grands changements stratégiques du début du XXe siècle.

On the basis of the digital soil map of Wallonia (1/20000), a decision tree is proposed for attributing infiltration class to each soil type. The proposition takes into account soil texture, drainage characteristics, substratum and, when appropriate, percentage of stoniness. The so defined infiltration classes are coherent with SCS methodology for abstraction computation (continuous or event based modelling). There are four groups named A, B, C and D from higher to lower basic infiltration rate. The map produced is a raster with a ground resolution of 10 meters, covering Wallonia (16900 km²), readily usable in hydrological distributed models. The paper deals with the classification and its inherent limitations. [less ▲]

In order to improve the photocatalytic properties of tin dioxide, crystallized powders of SnO(2) photocatalysts doped by alkali metals (Li, Na and K) were synthesized by sol-gel process. The physical properties of these materials were characterized by X-ray diffraction, nitrogen adsorption-desorption, Scanning electron microscopy and Ultraviolet-visible diffuse reflection spectroscopy. The photocatalytic tests under UV radiation conducted on four aromatic compounds (phenol, paranitrophenol, pentachlorophenol and benzoic acid) showed that tin dioxide modified by sodium possesses good photocatalytic activity; The Li-doped SnO(2) is moderately active, while modification by potassium does not improve this activity.

Drug eruptions are frequently encountered. Their putative diagnosis is based on a set of imputability arguments. The histopathological aspect is often evocative of the nature of the dermatosis. It varies according to the type of drug reaction. Some drug eruptions follow a benign course, but others are life-threatening. [less ▲]

The Nimba Mountains consist of a 40km-long scenic mountain chain, which extends along the tri-national border between Guinea, Côte d’Ivoire and Liberia. Their unique biogeographical characteristics have led to the differentiation of multiple micro-climates and ecological niches, which have favored the emergence of highly diverse wildlife and landscapes. They form a varied but single ecological and anthropological entity that is torn between different administrative and protective statuses. The Nimba Mountains have benefited from an early protective status, which was favored by the numerous scientific investigations initiated in the 1940s. Threats to biodiversity, including chimpanzees, are tightly linked to habitat destruction, which is mainly due to the increasing human pressures. The biggest challenge consists of dealing with the trade-off between biodiversity preservation and local development. This reinforced the necessity for elaborating a global and coherent transnational program of natural resource management. [less ▲]

Although cellulosic biomass offers a promising alternative as an abundant renewable resource in the production of biofuels and platform chemicals, so far only a few studies have reported its aqueous-phase conversion into glucose or sugar alcohols using solid chemocatalysts. The principal reason is that these polymeric biomolecules with semi-crystalline structure cannot penetrate the pores of conventional heterogeneous chemocatalysts. New advances in the conversion of cellulose thus require the design of efficient multifunctional catalytic systems with sterically accessible acid and metal sites. [less ▲]

Breast carcinoma is a major cause of death among women, and the potential implication of viruses in its pathogenesis remains worth a hypothesis. The potential role of Epstein-Barr virus (EBV) in its pathogenesis is still a subject of continued discussion and investigation. The aim of this study was to evaluate the prevalence of EBV in sporadic breast cancers in Tunisia, and to determine the clinicopathological characteristics of virus-positive cases. Viral presence has been evaluated by polymerase chain reaction (PCR), in situ hybridization, and immunohistochemistry investigated on tumor tissues and their corresponding normal breast tissues collected from 123 Tunisian women with sporadic breast carcinomas. Viral status in tumors was then correlated with various clinicopathological parameters. Using specific PCR assays, EBV DNA was found in 33 (27%) out of 123 breast carcinoma cases. EBV-encoded small RNAs (EBERs) in situ hybridization was negative in the neoplastic cells, but stomal lymphocytes were positive in 4 cases. Immunohistochemistry for latent membrane protein 1 (LMP1) was negative in all cases. None of the normal breast tissues showed positive results for EBV using PCR, in situ hybridization, and immunohistochemistry. A correlation was found between EBV DNA presence and the negativity of estrogen receptor (P=0.008). However, no significant correlation was found for the other parameters investigated, including patient age, Scarff-Bloom-Richardson (SBR) histological grade, tumor size, and histological node involvement. With regard to survival data, overall and disease-free survivals were shorter in EBV-positive breast carcinoma cases than in EBV-negative ones, but this difference did not reach statistical significance. Our study indicates the presence of EBV DNA in a significant proportion of breast cancer in Tunisia. Further studies are required to elucidate the role of this virus in breast carcinogenesis.

Phylloporia rzedowskii and Phylloporia ulloai , both collected in tropical forests of the Sierra of the Huasteca Potosina, San Luis Potosi, Mexico, are described as new species. The main critical morphological features that characterize them are the pileus shape, the pore diameter, the basidiospores shape and size, and, possibly, their ecology, such as the host relationships (specificity/preference). Both species also form distinct clades in phylogenetic analysis based on partial DNA sequences data from the nuclear ribosomal LSU. An identification key for 10 species reported from the Americas is proposed. [less ▲]
