la sociolinguistique est la partie de la linguistique ayant pour objet l’étude du langage sous son aspectsocioculturel. william labov est considéré dans la tradition anglo-saxonne, comme le fondateur de la sociolinguistique modern. c’est lui qui, en 1966, publie “the social stratification of english in new york city” ( la stratification social de l’anglais à new york). la recherche sociolingu...
all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
A new species of parasitoid wasp, Meteorus rugonasus Shaw and Jones (Hymenoptera: Braconidae), is described from the Yanayacu Biological Station, Napo Province, Ecuador. The new species is diagnosed and compared to other species in the genus. It was reared from larvae of Pteronymia zerlina (Hewitson, 1855) (Lepidoptera: Nymphalidae, Ithomiinae) found feeding on leaves of Solanum (Solanaceae). T...
An analysis of the J/ψ→ηη′γ decay by BESIII collaboration claims observation an exotic state η1(1855) with IGJPC=0+1−+. To establish its C-parity partner η1′(1855) in picture KK¯1(1400) molecular state, we propose that J/ψ→η1′(1855)η(′) receives main contributions from final interaction KK⁎(K+K⁎−, K−K⁎+, K0K¯⁎0, and K¯0K⁎0). Specifically, K K⁎ J/ψ→KK⁎ decays transform as η1′(1855)η(′), exchangi...
The first All-Russian Congress of Physiologists was held in Petrograd (Saint Petersburg), Russia in April 1917 at the Medical Institute for Women (11). Ivan Pavlov was the chairman of the organizing committee for this first “Sechenov Physiological Congress,” but he was unable to attend because of a fractured hip sustained in a fall on December 27, 1916 (7). Nevertheless, Pavlov wrote an address...
Attribute reduction of an information system is a key problem in rough set theory and its applications. Using computational intelligence (CI) tools to solve such problems has recently fascinated many researchers. CI tools are practical and robust for many real-world problems, and they are rapidly developed nowadays. However, some classes of CI tools, like memory-based heuristics, have not been ...
among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...
august wilson is undoubtedly one of the rare black playwrights whose works have attracted streams of attention and worldwide audience. the present study aims at analyzing fences and piano lesson which are two of the most successful plays in his pittsburgh cycle from the perspective of michel foucault’s theories and ideas. studying these two plays from foucault’s perspective opens new windows in...
a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...
The genus-group Hystricella R. T. Lowe, 1855 is revised on the basis of conchological, anatomical and genetic characteristics. A new genus Wollastoniagen. n., two recent species, W. jessicaesp. n. and W. klausgrohisp. n., and one recent subspecies, W. jessicae monticolassp. n. are described as new to science, as well as five fossil taxa, H. microcarinatasp. n., W. beckmannisp. n., W. falkneroru...
