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).

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 ▲]

In this note, we first present three different types of generalized inverse matrices (conditional, least squares and MOORE-PENROSE inverse matrices), as well as some of their properties. Applications of these inverse matrices in the linear model are then examined (normal equations solutions, orthogonal projections, sums of squares and their sampling distributions, estimations of parametric functions and sums of squares related to hypotheses testing).

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.

In this presentation, I attempt to examine the relationship between the Succession Regulation (650/2012) and matrimonial property. I do so by looking at the difficulties which could arise both from a practical perspective as well as from a more fundamental angle. Attention is given to the future Matrimonial Property Regulation and the need to coordinate it with the Succession Regulation. [less ▲]

In myeloid leukemia, immature leukemic cells are able to egress into peripheral blood to infiltrate extra-medullary organs. We therefore analyzed the migrating and invasive potential of human HL-60 and NB4 cell lines, representative of acute myelogenous leukemia, their ability to express matrix metalloproteases (MMPs), tissue inhibitors of metalloproteases (TIMPs) and urokinase plasminogen activator (uPA) in response to differentiating agents. Granulocytic differentiation by all-trans-retinoic acid (ATRA) and aclacinomycin (ACLA) strongly increased HL-60 and NB4 cell migration and invasion. At mRNA and protein levels, these cell lines produced significant amounts of MMP-9 (HL-60 < NB4). Granulocytic differentiation by ACLA increased both pro and active forms of MMP-9 whereas ATRA decreased them and stimulated uPA mRNAs. TIMP-1, the physiological MMP inhibitor, increased during granulocytic differentiation whereas TIMP-2 did not significantly vary. Use of Batimastat and aprotinin suggests that ATRA was active by modulating the uPA system while ACLA interfered with MMP expression. In conclusion, our data demonstrate that HL-60 and NB4 cells express MMPs and uPA which are differentially regulated by the differentiating agents ATRA and ACLA and suggest the clinical usefulness of MMPs and serine protease inhibitors in the prophylaxis and treatment of the ATRA syndrome.

The feasibility of laser—induced breakdown spectroscopy as a diagnostic tool for elementary analysis was documented widely,as well as the matrix effect of target material was proved to be remarkable impact on the spectral analysis. The influence of physical characteristics of fine coal,including particle size and area density,on the emission spectrum was surveyed,such as spectral intensity,standard deviation of characteristic spectrum and the detection threshold.An intense laser radiation with a wavelength of 1064 nm was used to ablate fine coal to form plasma plume,and the emission spectrum emitted as the plasma cooling of was analyzed by high—resolution echelle grating spectrometer coupled to intensified CCD camera.The results suggest that moderate particle size and material density are more advantageous to quantitative analysis of coal by laser—induced breakdown spectroscopy than the smallest or biggest size,which can be interpretable by heat—transfer mechanism in target after a shot of laser pulse.

We present explicit formulas for the matrix elements of the SU(6) generators for totally symmetric spin-flavor states, relevant for baryon spectroscopy in large N-c QCD. We rely on the interplay between two different methods to calculate these matrix elements. As an outcome, general analytic formulas of the corresponding SU(6) isoscalar factors are derived for arbitrary N-c. These results can be used to study excited states of nonstrange and strange baryons. [less ▲]

We derive general analytic formulae for the matrix elements of the SU(6) generators for mixed symmetric $[N_c-1,1]$ spin-flavor states with an arbitrary number $N_c$ of quarks. They are relevant for baryon spectroscopy in the $1/N_c$ expansion method applied to light baryons and can be used to study excited states. In this way previous work on non-strange baryons can be extended to both non-strange and strange baryons. [less ▲]
