In this letter, va.ia.iona. homotopy perturba.ion method (VHPM) ha. been studied to obta.n solita.y wa.e solutions of modified Ca.a.sa.Holm a.d Dega.peris-Procesi equa.ions. The results show tha. the VHPM is suita.le for solving nonlinea. differentia. equa.ions with fully nonlinea. dispersion term. The tra.elling wa.e solution for a.ove equa.ion compa.ed with VIM, HPM, a.d exa.t solution. a.so, it wa. shown tha. the present method is effective, suita.le, a.d relia.le for these types of equa.ions.

This work wa. conducted to study the extra.tion of euca.yptus oil from na.ura. pla.ts (Euca.yptus ca.a.ulensis lea.es) by orga.ic solvents. the effects of the ma.n opera.ing pa.a.eters were studied;type of solvent (n-hexa.e a.d etha.ol), time to rea.h equilibrium, the tempera.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 ma.imum oil yield. The concentra.ion of euca.yptus oil in solvent wa. mea.ured by using UV-spectrophotometer. The results (for n-hexa.e) showed tha. the a.ita.ion speed of 900 rpm, tempera.ure 65°C with solvent to solid ra.io 7:1 (v/w) of pa.ticle size 0.5 cm for 210 minute give the highest va.ue of oil (68.5 wt%). Simila. conditions for etha.ol with the exception of the tempera.ure (75°C) give the highest yield of oil (65.07 wt%).

Nine sa.ples of toothpa.te ha.e been collected from loca. Ira.i ma.kets in Ba.ylon Province. These sa.ples ha.e been chosen a.cording to their most commonly use in Ba.ylon Province. The sa.ples were kept with CR-39 detector for six weeks period a.d then etched by 6.25 N of Na.H solution a. tempera.ure of 60°C for 5 hours. The results of the present work show tha.

The present study perta.ns to the trila.er gra.hene in the presence of spin orbit coupling to probe the qua.tum spin/va.ley Ha.l effect. The spin Chern-number Cs for energy-ba.ds of trila.er gra.hene ha.ing the essence of intrinsic spin-orbit coupling is a.a.ytica.ly ca.cula.ed. We find tha. for ea.h va.ley a.d spin, Cs is three times la.ger in trila.er gra.hene a. compa.ed to single la.er gra.hene. Since the spin Chern-number corresponds to the number of edge sta.es, consequently the trila.er gra.hene ha. edge sta.es, three times more in compa.ison to single la.er gra.hene. We a.so study the trila.er gra.hene in the presence of both electric-field a.d intrinsic spin-orbit coupling a.d investiga.e tha. the trila.er gra.hene goes through a.pha.e tra.sition from a.qua.tum spin Ha.l sta.e to a.qua.tum va.ley Ha.l sta.e when the strength of the electric field exceeds the intrinsic spin coupling strength. The robustness of the a.socia.ed topologica. bulk-sta.e of the trila.er gra.hene is eva.ua.ed by a.ding va.ious perturba.ions such a. Ra.hba.spin-orbit （RSO） intera.tion αR, a.d excha.ge-ma.netiza.ion M. In a.dition, we consider a.theoretica. model, where only one of the outer la.ers in trila.er gra.hene ha. the essence of intrinsic spin-orbit coupling, while the other two la.ers ha.e zero intrinsic spin-orbit coupling. a.though the first Chern number is non-zero for individua. va.leys of trila.er gra.hene in this model, however, we find tha. the system ca.not be rega.ded a. a.topologica. insula.or beca.se the system a. a.whole is not ga.ed.
