Phenomenon of Partial and Total Albinism in the Hybrid Sparrows Passer Domesticus X Passer Hispaniolensis in Algeria : Phenomenon of Albinism in the Hybrid Sparrows

The phenomenon of albinism is repeated several times in sparrows, where as of december 8, 2018, a case of a male sparrow was observed in the city of Metlili (Ghardaïa - South Algeria), with a remarkably whitish color. Another observation of three (03) cases of total albinism in young males observed in Algiers in June 2007, precisely in Bir Khadem (Algiers - Northern Algeria)

Interfacial stresses analysis of FGM porous structures bonded with FRP plates

This paper presents a method for determining the interfacial stresses in an adhesive joint between a strengthening plate and a functionally graded beam. The beam is assumed to be isotropic with a constant poisson’s ratio. The present method is based on the deformation compatibility principle taking into account the neutral axis position of the FG beam. A power law for the distribution of the mechanical characteristic with a uniform and non-uniform porosity distribution is presented. A parametric study is presented to show the effect of some parameters on the distribution of stresses in the adhesive joint between the plat and the beam
