SIRMIP network is composed of a mechanical and a telemetric sensing system. SIRMIP network consists of, among others, 230 rain gauges and 137 thermometers.</p> <p>Rainfall and air temperature data have been interpolated on a 1 km-resolution regular grid using Inverse Distance Weighting (IDW) spatial interpolation. Temperature data were further processed through a linear regression using elevation from a high-resolution digital terrain model (DTM).</p> <p><strong>Results:</strong> The generated dataset described in this paper consists of 228 monthly- and 19 annual-spatially distributed maps of rainfall and air temperature.</p> Marco Pellegrini ##submission.copyrightStatement## http://journalajr2p.com/index.php/AJR2P/article/view/30106 Mon, 26 Aug 2019 00:00:00 +0000 Study of Energy of Formation for FexNi1-x Liquid Binary Alloys http://journalajr2p.com/index.php/AJR2P/article/view/30105 <p>In this present study we have systematically calculated the free energy of formation for Fe<sub>x</sub>Ni<sub>1-x</sub> binary alloys at a thermodynamic state T = 1920 K. A microscopic theory bases on first order perturbation theory along with a reference hard sphere liquid has been applied. The interionic interaction is described by Bretonnet-Silbert local pseudopotential that capable of takes into account the s-d hybridization in electro-ion interaction in transition metals. The effective hard sphere diameters have been determined using linearized Weeks-Chandler-Andersen (LWCA) perturbation theory and the partial structure calculated in line with Ashcroft and Langreths original work. The calculated theoretical value and available experimental data for free energy of formation are in agreement quite satisfactorily.</p> M. S. S. Chowdhury, Mohammad A. Rashid, M. A. Rahman, A. Z.
