Islamic Art is the art of civilization based on Islamic religion. Moreover, it not only concerned with particular region or particular people rather it is a combination of different civilizations and historical circumstances as painted with Islamic weltanschauung. The Arab civilization is probably more important. Although the Arabs have little art and even then, they developed Islamic art with ...

Introduction. A pseudoline is formed from a line by stretching the plane without tearing: it is the image of a line under a homeomorphism of the plane [13]. In arrangements of pseudolines, pairs of pseudolines intersect at most once and cross at their intersections. Pseudoline arrangements can be used to model sorting networks [1], tilings of convex polygons by rhombi [4], and graphs that have ...

We generalize the Hadwiger theorem on line transversals to collections of compact convex sets in the plane to the case where the sets are connected and the transversals form an arrangement of pseudolines. The proof uses the embeddability of pseudoline arrangements in topological affine planes. In 1940 Santaló showed [8], by an example, that Vincensini’s proof [9] of an extension of Helly’s theo...

Let G be a graph embedded in the plane and let A be an arrangement of pseudolines intersecting the drawing of G. An aligned drawing of G and A is a planar polyline drawing Γ of G with an arrangement A of lines so that Γ and A are homeomorphic to G and A. We show that if A is stretchable and every edge e either entirely lies on a pseudoline or intersects at most one pseudoline, then G and A have...

Heart failure is one of the chronic conditions of heart in the elderly people. The current study aimed to determine the effects of education on knowledge and practice of hospitalized heart failure patients regarding their self-care behaviors. This was a quasi-experimental study with control group which was conducted on 140 patients hospitalizing in Zahedan. The primary information was gathered ...
