This work wa. conducted to study the extra.tion of euca.yptus oil from.na.ura. pla.ts (Euca.yptus ca.0}dulensis lea.es) by orga.ic solvents. the effects of the m.in opera.ing pa.a.0}ters were studied;type of solvent (n-hexa.e a.d etha.ol), tim. to rea.h equilibrium. the tem.era.ure (45°C to 65°C) for n-hexa.e a.d (45°C to 75°C) for etha.ol, solvent to solid ra.io (5:1 to 8:1 (v/w)), a.ita.ion speed (0 to 900 rpm. a.d the pa.ticle size (0.5 to 2.5 cm. of fresh lea.es to find the best processing conditions for the a.hieving m.xim.m.oil yield. The concentra.ion of euca.yptus oil in solvent wa. m.a.ured by using UV-spectrophotom.ter. The results (for n-hexa.e) showed tha. the a.ita.ion speed of 900 rpm. tem.era.ure 65°C with solvent to solid ra.io 7:1 (v/w) of pa.ticle size 0.5 cm.for 210 m.nute give the highest va.ue of oil (68.5 wt%). Sim.la. conditions for etha.ol with the exception of the tem.era.ure (75°C) give the highest yield of oil (65.07 wt%).

Grounding Points (GPs) a.e insta.led in electrica. power system.to drive protective devices a.d a.com.lish the person nel sa.ety. The genera. grounding problem.is to find the optim.l loca.ions of these points so tha. the security a.d reli a.ility of power system.ca. be im.roved. This pa.er presents a.pra.tica. a.proa.h to find the optim.l loca.ion of GPs ba.ed on the ra.ios of zero sequence rea.ta.ce with positive sequence rea.ta.ce (X0/X1), zero sequence resista.ce with positive sequence rea.ta.ce (R0/X1) a.d Ground Fa.lt Fa.tor (GFF). The optim.l va.ues of these indica.ors were deter-m.ned by considering severa. scena.ios of fa.lt disturba.ces such a. single line to ground on a.selected a.ea.of the Ira.i Na.iona. Grid (132 KV) ta.ing into a.count the sta.ue of GPs for tra.sform.rs in the other substa.ions. From.the presented results in this pa.er, it is noted tha. GFF ca.cula.ed for som. substa.ions could be used to m.a.ure the effectiveness of GPs. However, the opera.ed tim. of rela. ca. be ta.en a. a.criterion of this m.a.urem.nt for selecting the best loca.ion of GPs.
