BACKGROUND Public hospitals can privatize management activities by contracting with a private organization or person to perform the work. Management contract is a method which uses private sector for major government projects like hospitals. This study evaluates contract management in health care institutes of developing countries. METHODS Information has been collected by reviewing the manag...

We report a new visual illusion, "directionless vection." When expanding and contracting optic flows are simultaneously presented in the same depth plane, observers can perceive illusory self-motion (vection) without direction.

public hospitals can privatize management activities by contracting with a private organization or person to perform the work. management contract is a method which uses private sector for major government projects like hospitals. this review study evaluated management contract conditions in selected countries. we focused on services under contract, different forms of management contract, metho...

We consider weakly regular Gowdy–symmetric spacetimes on T3 satisfying the Einstein– Euler equations of general relativity, and we solve the initial value problem when the initial data set has bounded variation, only, so that the corresponding spacetime may contain impulsive gravitational waves as well as shock waves. By analyzing, both, future expanding and future contracting spacetimes,we est...

In this paper we conjecture that the piecewise linear map f(x) = px1I[0,1/p)(x)+ (sx − s/p)1I[1/p,1](x), p > 1, 0 < s < 1 which has an expanding, onto branch and a contracting branch is eventually piecewise expanding. We give a partial proof of the conjecture, in particular for values of p and s such that d− ln(p(1−s)+s) ln s e 6 = d− ln p ln s e.

We show that if a closed n-manifold Mn (n ≥ 3) admits a structurally stable diffeomorphism f with an orientable expanding attractor Ω of codimension one, then Mn is homotopy equivalent to the n-torus Tn and is homeomorphic to Tn for n 6= 4. Moreover, there are no nontrivial basic sets of f different from Ω. This allows us to classify, up to conjugacy, structurally stable diffeomorphisms having ...
