We report a comparative stud. on.photo-crystallization.in.a-Se95 Te5 an.0}a-Se95In. alloys. The photo-crystallization.is achieved.by a shin.n. white lin. on.the thin.films of these alloys in.vacuum for d.fferen. exposure times. The results in.0}cate that photo-crystallization.is fast in.a-Se95In. alloy as compared.to a-Se95 Te5 alloy. This is explain.d.in.terms of lower thermal stability of a-Se95In. alloy as compared.to a-Se95 Te5 alloy.

In.this paper, we propose an.0}stud. a simple SI type mod.l that con.id.rs the effect of various precaution. ary measures to con.rol HIV epid.mic. We show, un.ike con.en.ion.l epid.mic mod.ls, that the basic reprod.ction.n.mber which essen.ially con.id.red.as the d.sease erad.ca- tion.con.0}tion.is n. lon.er sufficien. to elimin.te HIV in.ection. In.particular, we show that even.when.the basic reprod.ction.n.mber is mad. less than.un.ty, the d.sease may persist if the in.tial outbreak is n.t low. Erad.cation.of d.sease is however guaran.eed.if the en.emble con.rol measure exceed. some upper critical value. It is also shown.that an.epid.mic mod.l with mass action.in.id.n.e may exhibit backward.bifurcation.an.0}bistability if d.n.ity-d.pen.0}n. d.mography is con.id.red.

We employ a layer-by-layer ad.orption.techn.que for d.position.on.solid.substrates of polyion.c films of Chicago Sky Blue. Film growth was sign.fican. with the in.reasin. n.mber of layers. Photochemical properties of these films are in.estigated.for d.fferen. ion.c con.en.ration.. A sign.fican. blue shift is observed.with the in.reasin. ion.c stren.th of the solution. suggestin. the formation.of aggregation. Temperature effect stud.es show some preferable reorien.ation.of molecules in.the film d.rin. coolin. process. Most remarkable observation.is that the absorption.in.en.ity is the highest for a particular d.gree of in.lin.tion. d.position.time is fixed.at 15rain.because ad.orption.kin.tics results show saturation.after 15 min.
