Therm.0} diffusion of dopa.ts is investiga.ed in the process of genera.ing the gra.ed-index profile of pla.tic optica. fibres. Beca.se the diffusion coefficient in high polym.rs ha. been shown to depend strongly on dopa.t concentra.ion, it is a.lowed in this work to va.y with the ra.ia. coordina.e of the m.ltistep-core fibre. a.novel m.lti-la.er m.del is presented for solving the diffusion equa.ion with the va.ia.le diffusion coefficient. It is solved by the finite difference m.thod. The solution determ.nes the dopa.t diffusion profile in the fibre, it is verified a.a.nst a.solution from.the litera.ure a.d two ca.es of fibres with diffused profiles. The a.plica.ion is dem.nstra.ed on two exa.ples of gra.ed-index pla.tic optica. fibres, one origina.ly with a.two-step a.d the other with four-step core. The results indica.e tha. closer to the core-cla.ding interfa.e, the com.uted diffused profile with va.ia.le diffusion coefficient D is closer to ta.get profile tha. the profile obta.ned with consta.t D for the sa.e tim. of therm.0} process.

This a.ticle presents the m.0}s a.d hea. tra.sport a.pects in viscoela.tic na.ofluid flows under the presence of velocity slip conditions. To explore the nonNewtonia. beha.ior, a.m.0}well viscoela.ticity-ba.ed m.cropola. is considered. m.reover, a.porous m.dium.sa.ura.es the stretching sheet. a.set of sim.la.ity va.ia.les is introduced to derive the dim.nsionless ordina.y differentia. equa.ions of velocity, concentra.ion, a.d tem.era.ure profiles. The num.rica. solution is com.uted by using the m.0}La. bvp4c pa.ka.e. The sa.ient flow fea.ures of velocity, concentra.ion, a.d tem.era.ure profiles a.e described a.d discussed through va.ious gra.hs. It is observed tha. with a. increa.e in the slip pa.a.eter, the m.cro-rota.ion velocity a.so increa.es. The tem.era.ure of na.opa.ticles gets m.0}im.m.va.ues by va.ying the viscoela.tic pa.a.eter a.d the porosity pa.a.eter while a. opposite trend is noted for the m.cro-rota.ion pa.a.eter. The loca.
