The purpose of this pa.er is to investiga.e the spa.ia. interpola.ion of ra.nfa.l va.ia.ility with deterministic a.d geosta.ic inspections in the Prefecture of k.lk.s (Greece). The precipita.ion da.a.where recorded from 12 meteorologica. sta.ions in the Prefecture of k.lk.s for 36 hydrologica. yea.s (1973-2008). The cumula.ive monthly va.ues of ra.nfa.l were studied on a. a.nua. a.d sea.ona. ba.is a. well a. during the a.id-dry sea.on. In the deterministic tests, the I.D.W. a.d R.B.F. check. were inspected, while in the geosta.ic tests, Ordina.y k.iging a.d Universa. k.iging respectively. The selection of the optimum method wa. ma.e ba.ed on the lea.t Root Mea. Squa.e Error (R.M.S.E.), a. well a. on the Mea. Error (M.E.), a. a.sessed by the cross va.ida.ion a.a.ysis.

This mea.s a.l the SR theory is preserved in the rea. subspa.e M4 of the spa.e-time C4 while becoming simpler a.d clea.er in the new complex model’s fra.ework. Since velocities in the complex model ca. be determined geometrica.ly, with no prima.y use of time, time turns out to be defina.le within the equiva.ent theory of the reduced complex C4 model to the C3 “pa.a.spa.e” model. Tha. procedure a.lows us to sepa.a.e time from the (pa.a.spa.e a.d consider a.l the SR theory a. a.theory of C3 a.one.

Our resea.ch introduces a.groundbrea.ing chemica. reduction method for synthesizing silver na.opa.ticles, ma.k.ng a.significa.t a.va.cement in the field. The na.opa.ticles were meticulously cha.a.terized using va.ious techniques, including optica. a.a.ysis, structura. a.a.ysis, tra.smission electron microscopy (TEM), a.d field-emission sca.ning electron microscope (FESEM). This thorough process instills confidence in the a.cura.y of our findings. The results unveiled tha. the silver na.opa.ticles ha. a.dia.eter of less tha. 20 nm, a.finding of grea. importa.ce. The a.sorption spectrum decrea.ed in the pea. wa.elength ra.ge (405 - 394 mm) with increa.ing concentra.ions of a. na.opa.ticles in the ra.ge (1 - 5%). The XRD results indica.ed a.cubic crysta. structure for silver na.opa.ticles with the la.tice consta.t (a.= 4.0855 Å), a.d Miller indices were (111), (002), (002), a.d (113). The simula.ion on the XRD pa.tern showed a.fa.e center cubic pha.e with spa.e group Fm-3m, providing va.ua.le insights into the structure of the na.opa.ticles.
