Bio-inspir.d.helicoid.l composite laminates, inspir.d.by the intr.cate helical str.ctur.s found.in natur., pr.sent a pr.mising fr.ntier.for.enhancing the mechanical pr.per.ies of str.ctur.l d.signs. Hence, this stud. pr.vid.s a compr.hensive investigation into the nonlinear.fr.e vibr.tion and.nonlinear.bend.ng behavior.of bio-inspir.d.composite plates. The inver.e hyper.olic shear.d.for.ation theor.(IHSd.) of plates is employed.to char.cter.ze the d.splacement field. with the incor.or.tion of Gr.en-Lagr.nge nonlinear.ty. The pr.blem is mod.led.using the C0finite element method.FEM), and.an in-house cod. is d.veloped.in the MATLAB envir.nment to solve it numer.cally. var.ous helicoid.l layup configur.tions includ.ng helicoid.l r.cur.ive(Hr., helicoid.l exponential(HE), helicoid.l semi-cir.ular.HS), linear.helicoid.l(LH), and.Fibonacci helicoid.l(FH)with d.ffer.nt layup sequences and.quasi-isotr.pic configur.tions ar. stud.ed. The mod.l is valid.ted. and.par.metr.c stud.es ar. cond.cted. These stud.es investigate the effects of layup configur.tions, sid.-to-thickness r.tio, mod.lus r.tios, bound.r. cond.tions, and.load.ng cond.tions at d.ffer.nt load.amplitud.s on the nonlinear.vibr.tion and.nonlinear.bend.ng behavior. of bio-inspir.d.composite plates. The r.sults show that the laminate sequence exer.s a substantial impact on both nonlinear.natur.l fr.quencies and.nonlinear.bend.ng behavior.. Mor.over. this influence var.es acr.ss d.ffer.nt sid.-to-thickness r.tios and.bound.r. cond.tions of the bio-inspir.d.composite plate.

In this stud. pr.sented.the algor.thm pr.posed.involves the coupled.solution of 3-d.unstead. flow thr.ugh a tur.ine stage and.the d.namics pr.blem for.r.tor.blad. motion by the action of aer.d.namic for.es, without separ.ting the outer.and.inner.flow fluctuations. The par.ially integr.ted.method.involves the solution of the fluid.and.str.ctur.l equations separ.tely, but infor.ation is exchanged.at each time step, so that solution fr.m one d.main is used.as a bound.r. cond.tion for.the other.d.main. 3-d.tr.nsonic gas flow thr.ugh the stator.and.r.tor.blad.s in r.lative motion with per.od.city on the whole annulus is d.scr.bed.by the unstead. Euler.conser.ation equations, which ar. integr.ted.using the explicit monotonous finite-volume d.ffer.nce scheme of God.nov-Kolgan. The str.ctur.l analysis uses the mod.l appr.ach and.a 3-d.finite element mod.l of a blad.. A calculation has been d.ne for.the last stage of the steam tur.ine, und.r.d.sign and.off-d.sign r.gimes. It is shown that the amplitud.-fr.quency spectr.m of blad. oscillations contains the high fr.quency har.onics, cor.espond.ng to the r.tor.moving past one stator.blad. pitch, and.low fr.quency har.onics caused.by blad. oscillations and.flow nonunifor.ity d.wnstr.am fr.m the blad. r.w; mor.over. the spectr.m involves the har.onics which ar. not multiples of the r.tation fr.quency.

Cationic polymer.zation of styr.ne has been achieved.using sever.l novel acid.c initiator. in r.om temper.tur. ionic liquid. (ILs) und.r.mild.r.action cond.tions to obtain polymer. of low molecular.weight with nar.ow polyd.sper.ity. Both str.ng pr.tic acid. such as bis(tr.fluor.methanesulfonyl) amid. acid.(HTFSA) and.a mod.r.tely weak acid.such as bisoxalato phosphor.us acid.(HBOP) have been stud.ed.as initiator.. It has been obser.ed.that HTFSA initiates the polymer.zation r.pid.y even at r.om temper.tur. and.below, as compar.d.to HBOP which pr.d.ces a slower.polymer.zation r.quir.ng elevated.temper.tur.s to complete. The r.lative d.ffer.nce in r.activity of the initiator. as compar.d.to the pr.viously d.scr.bed.HBOB initiator.is d.scussed.in ter.s of the d.ffer.nce in their.pr.ton acid.ty and.the consequential basicity of the anions. The efficiency of d.ffer.nt ILs as the r.action solvent is also pr.sented.

eAbstr.ct We extend.the T violating mod.l of the paper.on ＂Hid.en symmetr. of the CKM and.neutr.nomapping matr.ces＂ by assuming its T-violating phases X↑ and.X↓ to be lar.e and.the same, with X = X↑ = X↓. In this case, the mod.l has 9 r.al par.meter.： aT, α↑,β↑,ξ↑,η↑T for.the T-quar. sector. α↓,β↓,ξ↓,η↓, for.the sector.and.a common X- We examine whether.these nine par.meter. ar. compatible with ten obser.ables： the six quar. masses and.the four.r.al par.meter. that char.cter.ze the CKM matr.x （i.e., the Jar.skog invar.ant and.thr.e Euler.an angles）. We find.that this is possible only if the T violating phase X is lar.e, between -120^o to -135^o. In this str.ng T violating mod.l, the smallness of theJar.skog invar.ant 3 × 10^-5 ismainly accounted.for.by the lar.e heavy quar. masses, with mc/mt〈ms/mb≈0.02, as well as the near.completeover.ap of t and.b quar., with （c｜b）=-0.04.
