Most of the international relations theories explain that states form military alliances in response to common external threats. Conversely, alliances should disintegrate when the threats that occasioned their formation disappear. When the cold war ended in Europe, many observers ex¬pected that NATO\'s demise would soon follow. Even if the alliance did not disappear altogether, it would become an empty shell, no longer performing any useful functions. However, NATO has not become moribund. However, NATO has not only survived but has even added to its elaborate organizational bodies and undertaken new activities. We discuss in this article about Theoretical foundation expansion NATO after cold war.
This study aims to determine an appropriate spatial interpolation method in the mapping of various physical and hydraulic properties of soils. For this purpose, the Inverse Distance Weighted (IDW), Global Polynomial Interpolation (GPI), Local Polynomial Interpolation (LPI), Radial Basis Functions (RBF) and kriging spatial interpolation methods were used. \nThe method that produced the lowest root mean square error for each variable was deemed to be the best method for that variable. The best methods were determined to be RBF for infiltration, IDW for hydraulic conductivity at 0-30 cm depth, GPI for hydraulic conductivity at 30-60 cm depth, LPI for soil field capacity and soil wilting point, LPI for soil bulk density at 0-30 cm depth and RBF for soil bulk density at 30-60 cm depth. Thus, the most appropriate spatial interpolation methods were determined in mapping of the soil parameters mentioned.
