In this paper, I outline a general framework for cultural analysis consistent with an “analytic” approach to explanation in social science. The proposed provides coherent solutions thorny problems theory. These include providing definition of culture (and the “cultural”), specifying nature units (both simple and complex), outlining processes making possible episodes genesis, transformation, rep...

Let S = Sg,n be a connected, orientable surface of genus g ≥ 0 with n ≥ 0 punctures. Let Teich(S) denote the corresponding Teichmüller space, and let Mod(S) denote the mapping class group of S. Understanding the analogy of Teich(S) with symmetric spaces is a wellknown theme. Recall that a complete Riemannian manifold X is symmetric if it is symmetric at each point x ∈ X: the map γ(t) 7→ γ(−t) w...

We describe the geometry of geodesics on a Lorentz ellipsoid: give explicit formulas for the first integrals (pseudo-confocal coordinates), curvature, geodesically equivalent Riemannian metric, the invariant area-forms on the timeand space-like geodesics and invariant 1-form on the space of null geodesics. We prove a Poncelet-type theorem for null geodesics on the ellipsoid: if such a geodesic ...

We introduce a family of extremal polynomials associated with the prolongation of a stratified nilpotent Lie algebra. These polynomials are related to a new algebraic characterization of abnormal subriemannian geodesics in stratified nilpotent Lie groups. They satisfy a set of remarkable structure relations that are used to integrate the adjoint equations.

Female genital mutilation in different parts of the African continent isconsidered as one of the vast territory’s social problems. This social problem whichis accounted as an old tradition in different countries of the African continent hashad so many unpleasant physical and mental effects on urban and rural Africanwomen during recent centuries. Throughout recent decades, considerable effortsha...

An analytical solution is presented that reconstructs residual stress field from limited and incomplete data.  The inverse problem of reconstructing residual stresses is solved using an appropriate form of the airy stress function.  This function is chosen to satisfy the stress equilibrium equations together with the boundary conditions for a domain within a convex polygon.  The analytical solu...

the political and social system involved in the limbo between tradition and modernity of the qajar era caused widespread and quick developments in iranian culture, art, and architecture as well as a challenge between tradition and modernity. relatively numerous palaces built in this era were signs of greatness and distinction-seeking of the qajar kings and aristocrats, who embraced all transfor...

I was fascinated by the micrographs in this atlas. Once I had mastered the viewer, villi sprang from the page, while at the same time I peered into the depths of a mitochondrion. Because each image covers the entire visual field, I often felt as though I were strolling through the cell. I was equally fascinated by the authors' presentation of evidence suggesting that the classical interpretatio...
