Given a polygon P , a ipturn involves re ecting a pocket p of P through the midpoint of the lid of p. In 1973, Joss and Shannon (published in Gr unbaum (1995)) showed that any polygon on n vertices will become convex after a sequence of at most (n 1)! ipturns. They conjectured that this bound was not tight, and that n=4 ipturns would always be suÆcient. In this work, we show that any polygon o...

The development and application of techniques that allow to study and to understand the features of precipitations from remote sensing data have been an important object in a number of research. In the radar applications, a basic relation between the reflectivity of the radar and the rain rate must be defined for the region to be studied, that is the conversion of the radar reflectivity in rain...

OBJECTIVE To study the prevalence and factors associated with allergic rhinitis (AR) in the priest and novices who came for treatment in Priest Hospital MATERIAL AND METHOD The retrospective study of 110 priests with allergic rhinitis was conducted between January 2006 to June 2007.

Given the increasing threat of terrorism and spread of terrorist organizations, it is of vital importance to understand the properties of such organizations and to devise successful strategies for destabilizing them or decreasing their efficiency. However, intelligence information on these organizations is often incomplete, inaccurate or simply not available. This makes the study of terrorist n...

Droplets of natural clouds and precipitation satisfy the condition of Rayleigh Approximation, namely diameter much smaller than the wavelength, for wavelengths used in weather radars (Sauvageot H., 1992). If it is hypothesized that radars can monitor certain atmospheric phenomena, then the radar reflectivity factor (Z) can be related to physical quantities of these phenomena. Many works were pe...
