In females of both spontaneously and induced ovulating species, pheromones from male conspecifics can directly stimulate GnRH neuronal activity, thereby inducing pituitary LH secretion and stimulating the onset of estrus. However, whether pheromones contribute to the steroid- or mating-induced preovulatory activation of GnRH neurons is less clear. Previous studies in the ferret, an induced ovulator, raised the possibility that olfactory cues contribute to the ability of genital-somatosensory stimulation to activate GnRH neurons in the mediobasal hypothalamus (MBH). In the present study the percentage of GnRH neurons colabeled with Fos-immunoreactivity (IR), used as a marker for neuronal activation, was investigated in the MBH of mated gonadectomized, estradiol-treated female ferrets in which both nares were occluded. In addition, the percentage of GnRH neurons colabeled with Fos-IR was examined in the MBH of gonadectomized, estradiol-treated female ferrets exposed to male bedding. Bilateral nares occlusion successfully blocked mating or odor-induced increments in Fos-IR in central olfactory regions, including the cortical and medial amygdala. By contrast, the percentage of GnRH neurons expressing Fos-IR did not differ between mated nares- and sham-occluded females. Exposure to male bedding alone failed to induce Fos-IR in MBH GnRH neurons. Thus, the mating-induced preovulatory activation of GnRH neurons in the female ferret's MBH appears to rely solely on genital-somatosensory as opposed to olfactory inputs. [less ▲]

Mating patterns among first-generation hybrids of the roach, Rutilus rutilus, and the silver bream, Blicca bjoerkna, between hybrids or with parent-species males, have been investigated under experimental reproduction conditions. The results reveal that the level of sexual activity of these hybrids is high. Hybrid females mated simultaneously and successively with all types of male, resulting in fertilised eggs. Individual participation of roach males in mating was never observed, however. [less ▲]

Male sexual behavior is determined by the interaction of endocrine and environmental stimuli originating from the female, yet it is unknown how and where these stimuli are integrated within the brain. Activation of copulatory behavior by testosterone is limited by its central aromatization into an estrogen in the preoptic area. We investigated whether mating-induced neuronal activation as identified by the expression of the immediate early gene Fos occurs in aromatase-immunoreactive (ARO-ir) cells of the male quail preoptic area. Fos-immunoreactive (ir) cells were observed within and lateral to these ARO-ir cells groups but few ARO-ir cells contained Fos-ir indicating that mating-related stimuli do not directly affect estrogen-synthesizing cells.

MATISSE is foreseen as a mid-infrared spectro-interferometric instrument combining the beams of up to four UTs/ATs of the Very Large Telescope Interferometer (VLTI). MATISSE will measure closure phase relations and thus offer an efficient capability for image reconstruction. In addition to this, MATISSE will open 2 new observing windows at the VLTI: the L and M band in addition to the N band. Furthermore, the instrument will offer the possibility to perform simultaneous observations in separate bands. MATISSE will also provide several spectroscopic modes. In summary, MATISSE can be seen as a successor of MIDI by providing imaging capabilities in the mid-infrared domain (for a more detailed description of MATISSE see Lopez et al., these proceedings).

The interest of the chemical composition of molluscan shells in phylogenetical considerations is illustrated by the case of Neopilina. Chemical analyses of organic matrix of the different shell layers of Neopilina galatheae rovealed the presence of chitin in nacrous and prism layers. Chitin is lacking in periostracum. The proportion of chitin is low (about 3.3 % of shell decalcified weight). Both microstructural and chemical caracteristics are in favor of a closest relationship of Monoplacophora with primitive Conchifera rather than with Amphineura. [less ▲]

Le mouvement ouvrier chrétien, coupole de la confédération des syndicats chrétiens, de l'alliance nationale des mutualités chrétiennes, des coopératives chrétiennes, des jeunesses ouvrières chrétiennes, de Vie féminine et des Equipes populaires, a souvent été vu comme le pilier social du parti social chrétien. A l'inverse, celui-ci lui servait de relais politique privilégié. L'étude montre que le mouvement ouvrier chrétien a été déchiré par des tensions politiques fortes qui ont fait préférer à plusieurs dirigeants d'autres relais politiques que le PSC. [less ▲]

Le présent article décrit différentes limitations des matériaux composites à matrice polymère. Outre l’amélioration de la formulation des résines, une des alternatives qui se présente est d’employer une matrice métallique ou céramique. Certains de ces matériaux nouveaux sont toujours au stade du développement. Il s’agit par exemple des composites pour applications structurales avec une matrice légère en aluminium ou en magnésium pour lesquels les rapports rigidité-poids et résistance-poids sont élevés. La résilience est aussi améliorée par rapport aux matrices classiques simplement renforcées. D’autres composites à matrice métallique tels que les cermets sont industrialisés comme outils de coupe. Des composites à matrice céramique comme le carbone-carbone ou le carbone-SiC peuvent être industrialisés et présentent une durabilité et une température d’utilisation maximale exceptionnelle. Pour terminer, l’article fournit quelques informations sur les techniques nouvelles de mise à forme des matériaux composites telles que le friction stir processing et l’additive manufacturing.
