The egg release–mating comparison, heterospecific matings and mating success under two hybridization conditions – (i) mixing one sex per species and (ii) mixing both sexes from each species – were investigated to determine whether silver bream Blicca bjoerkna and common bream Abramis brama can hybridize in nature. The results revealed that non-matings in hybridization experiments of silver bream females × common bream males can be explained by territorial and aggressiveness activities observed in common bream. In common bream females × silver bream males, heterospecific matings were observed but their numbers were signifi cantly lower than the spawning numbers, and in this experiment, a female mated with one to four heterospecifi c males. In mixing both sexes from both species, similar spawning – mating numbers were observed but heterospecific matings accounted for only 27% of the total matings, with 24% accounting for heterospecifi c matings between common bream females and silver bream males, directly or by opportunism. Mating success was characterized by the occurrence of fertilized eggs after matings. Natural hybridization occurred preferentially between common bream females and silver bream males. [less ▲]

Taking into consideration the intangible cultural heritage holds a central position in the new challenges confronting today's various cultural communities. The author briefly repositions globalization and cultural diversity and shows that, faced with these two basic guidelines, communies' reactions can be radically opposed : acceptance or refusal of the multiculturalism and, in the case of refusal, an essentialist or evolutionary approach. The latter sacrifices heritage for the benefit of trends, supported by new technologies; the first emphasizes the use of an idealised past in what the author identifies as a policy of "folklorisation". Fortunately, some communities accomplish a positive combination and revitalize their heritage through new forms of communication. This is the case of the municipality of Clare in Nova Scotia, the flag-bearer of a growing Acadian identity. [less ▲]

We propose a coefficient of agreement to assess the degree of concordance between two independent groups of raters classifying items on a nominal scale. This coefficient, defined on a population-based model, extends the classical Cohen's kappa coefficient for quantifying agreement between two raters. Weighted and intraclass versions of the coefficient are also given and their sampling variance is determined by the Jackknife method. The method is illustrated on medical education data which motivated the research. [less ▲]

This paper is devoted to nonlinear numerical modeling of reinforced concrete columns subjected to fire. In this work we analyze reinforced concrete columns loaded by eccentric compressive forces and exposed to a standard fire. That the columns have an extremely important role in building, the verification of fire resistance in fire conditions is crucial. The analysis is divided into two steps. In the first step we make the thermal study of column. It follows the temperatures depending of time that we use in the second stage for the mechanical study, where we get the variation of different parameters such as bending moment, stresses, displacements and tangent modulus.

We evaluated the combination of vapor phase doping and sub-melt laser anneal as a novel doping strategy for the fabrication of source and drain extension junctions in sub-32 nm CMOS technology, aiming at both planar and non-planar device applications. High quality ultra shallow junctions with abrupt profiles in Si substrates were demonstrated on 300 mm Si substrates. The excellent results obtained for the sheet resistance and the junction depth with boron allowed us to fulfill the requirements for the 32 nm as well as for the 22 nm technology nodes in the PMOS case by choosing appropriate laser anneal conditions. For instance, using 3 laser scans at 1300 $\,^ rc$C, we measured an active dopant concentration of about 2.1 × 1020 cm− 3 and a junction depth of 12 nm. With arsenic for NMOS, ultra shallow junctions were achieved as well. However, as also seen for other junction fabrication schemes, low dopant activation level and active dose (in the range of 1--4 × 1013 cm− 2) were observed although dopant concentration versus depth profiles indicate that the dopant atoms were properly driven into the substrate during the anneal step. The electrical deactivation of a large part of the in-diffused dopants was responsible for the high sheet resistance values. [less ▲]

We analysed the spatial frequencies of birds and their distributions across three types of habitats (forests, plantations and various fallows) in the vegetation mosaic in the south of Benin from a total of 45 monitoring stations. 167 species belonging to 40 families were inventoried, the forest having 153 species and fallows and plantations having each 99 species. The similarity index of Jaccard showed 44.0% affinity between forests and flantations, 43.1% between forest and fallows, and 75.5% between forest and fallows. The analysis in main composent and ascending hierachical classification identified three local bird communities, namely for forests, plantations and fallows, ubiquitous in three areas and, respectively, aligned according to their need for intact forest or their propensity to tolerate changes in vegetation/ deforstation.

Graphical representations of power systems are systematically used for planning and operation. The coordinate systems commonly used by Transmission System Operators are static and reflect the geographical positions of each equipment of the system. We propose in this work to position on a twodimensional map the different buses of a power system in a way such that their coordinates also highlight some other physical information related to them. These pseudo-geographical representations are computed by formulating multidimensional scaling problems which aim at mapping a distance matrix combining both geographical and physical information into a vector of two-dimensional bus coordinates. We illustrate through examples that these pseudo-geographical representations can help to gain insights into the power system physical properties. [less ▲]
