In a tritrophic interaction including tomato plant (Lycopersicon esculentum Miller), the herbivore Myzus persicae (Sulzer) and the predator Episyrphus balteatus (De Geer), the perception of the tomato plants produced volatile organic compounds (VOC) by Episyrphus balteatus is investigated. In a first step, an odour sampling device has been set up aiming the headspace collection of the tomato plant VOC and their adsorption on Tenax adsorbent cartridges (Supelco®). Following desorption is held using a thermodesorption injector (Gerstel®) coupled with GC-MS. Intact and aphid infested plants are studied for their VOC emissions, as well as the comparison of the VOC emission of different tomato cultivars. These VOC consist mainly in mono- and sesquiterpenes (such as - and -pinene ; -humulene ; …) as well as in C6-volatiles like hexenal in case of infestation by herbivores Once the tomato plants VOC identified and quantified, they are tested for their perception by Episyrphus balteatus using electroantennography (EAG). Accordingly, an EAG device has been installed and configured for the study of VOC using Diptera antennas. The monoterpenes limonene and linalool showed high EAG activity whereas other terpenes like cymene seem to be inactive. [less ▲]

The author studies the use of the Marian worship as an identitary factor in the Catholic Low Countries (end 16th- 17th c.). She shows how, in a stormy military context, this symbolical character served as a principle of fusion, favouring the unity of the group and carrying therefore the individual to conform himself with common values i.e. fidelity to the reformed Catholicism and loyalty to the Habsburg authority.

Microarray technology is a miniaturized biotechnological tool with potential applications for study and analysis of multiple molecular compounds as proteins, lipids, carbohydrates or nucleic acids. The nucleic acids microarray technology focuses interest of scientists for fifteen years because of its huge potential as regard to the scientific research, clinical diagnosis, and development of new drugs. Only DNA microarrays are investigated in this paper. Born from the conjunction of micro-electronics, biochemistry, molecular biology, and image processing, microarrays allow to analyse several thousands of genetic information simultaneously. Thanks to this new tool, it is possible in parallel to identify, to even proportion, a considerable number of nucleic acid sequences contained in a biological sample (blood, biopsy, water, food, etc). This article proposes, after having considered the operating mode of the microarrays, to understand their quality standards as well as their advantages and disadvantages. The two following parts are devoted to the place the microarrays occupy in scientific research and in the establishment of a clinical diagnosis. Finally the last part evaluates prospects the microarrays offer in veterinary sciences. [less ▲]

This paper studies the aggregation of predictions made by tree-based models for several perturbed versions of the attribute vector of a test case. A closed-form approximation of this scheme combined with cross-validation to tune the level of perturbation is proposed. This yields soft-tree models in a parameter free way, and reserves their interpretability. Empirical evaluations, on classification and regression problems, show that accuracy and bias/variance tradeoff are improved significantly at the price of an acceptable computational overhead. The method is further compared and combined with tree bagging. [less ▲]

Les problèmes à la frontière belgo-allemande après 1945 font partie de ces épisodes oubliés de l'histoire des deux pays. Sur base d'une dcoumentation étoffée provenant d'archives belges et allemandes, cet article se propose de mettre en évidence la place de cette "question frontalière" dans le cadre de la politique belge à l'égard de l'Allemagne. Elle y est vue comme un indicateur des relations entre la Belgique et son grand voisin vaincu. Quels sont les projets de revendications territoriales aux dépens de ce dernier? Quels sont les acteurs derrière ces projets? Quel est le rôle du gouvernement belge? Et quelles sont les réactions des "concernés", de part et d'autre de la frontière? Telles sont les questions principales auxquelles l'article tente de répondre. [less ▲]

The zinc violet, Viola calaminaria (DC) Lej., is a rare threatened species in Belgium which is endemic to metalliferous sites. Yours aims were to assess the genetic structure of the species at the scale of its distribution range, including differentiation with related taxa Viola guesphalica and to examine the influence of population size and recent colonisation events on population genetic structure in order to identify conservation priorities. The analysis of genetic variation (Amova) showed a strong population differentiation (Fst = 0.26) with a regional group differentiation. The V. guestfalica population exhibits the larger differentiation (Fst = 0.19). The levels of population genetic diversity (Hs) varied from 0.21 to 0.29. Mean genetic differentiation among ancient populations (Fst =0.26) is higher than genetic differentiation among recent populations (Fst =0.18) while any difference appears on genetic diversity. This strong population differentiation suggests a low gene flow between populations but sufficient within population to maintain high level of diversity. For management, the result implies a hierarchical conservation strategy including small population. New populations had as much genetically importance than old populations. No foundation effects were detected in the recent populations. These populations probably result from multiple colonization effects from more than one source population. Finally, even if some V. calaminaria populations exhibit a similar level of genetic differentiation of V. guestfalica population, this one appeared as a particular genetic pool. [less ▲]
