The powders.of the AA 7075-ZRO2 were mixed by mechanical milling, but it was.found that the s.s.em pres.nts.a few disadvantages.when proces.ed by conventional s.ntering and hot extrus.on, s.nce intermetallic phas.s.between ZrO2 particles.and alloying elements.were formed. Equal channel angular pres.ing （EcAP） proces.ing was.propos.d as.an alternative method to cons.lidate the compos.te where there is.no intermetallic formation. The analys.s.of the EcAP proces. s.owed that the intermediate temperature （220℃） produced a higher cons.lidation level than conventional s.ntering and hot extrus.on （400 and 500℃, res.ectively）. This.fact was.s.pported by relative dens.ty analys.s. in the cas. of the s.ntered and hot-extruded s.mple, the relative dens.ty exhibited a value of 0.95, while EcAP s.mple s.owed a value of 0.98. Hardnes. values.s.ow that micros.ructural refinement obtained during mechanical milling was.pres.rved during EcAP proces.ing even when it was.carded out at 220℃.

We inves.igate the nonlinear behaviors.of light recognized as.chaos.during the propagation of Gaus.ian las.r beam ins.de a nonlinear polarization maintaining and abs.rption reducing （PANDA） ring res.nator s.s.em. it aims.to generate the nonlinear behavior of light to obtain data in binary logic codes.for trans.is.ion in fiber optics.communication. Effective parameters. s.ch as.refractive indices.of a s.licon waveguide, coupling coefficients.（~）, and ring radius.ring （R）, can be properly s.lected to operate the nonlinear behavior. Therefore, the binary coded data generated by the PANDA ring res.nator s.s.em can be decoded and converted to Manches.er codes. where the decoding proces. of the trans.itted codes.occurs.at the end of the trans.is.ion link. The s.mulation res.lts.s.ow that the original codes.can be recovered with a high s.curity of s.gnal trans.is.ion us.ng the Manches.er method.

We introduce the Dirac equation in four-dimens.onal gravity which is.a generally covariant form. We choos. the s.itable variable and s.lve the corres.onding equation. To s.lve s.ch equation and to obtain the corres.onding bis.inor, we employ the factorization method which introduces.the as.ociated Laguerre polynomial. The as.o- ciated Laguerre polynomials.help us.to write the Dirac equation of four-dimens.onal gravity in the form of the s.ape invariance equation. Thus.we write the s.ape invariance condition with res.ect to the s.condary quantum number. Finally, we obtain the s.inor wave function and achieve the corres.onding s.0}bility of condition for the four-dimens.onal gravity s.s.em.

The effect of permeable walls.and magnetic field on the peris.0}ltic flow of a carreau fluid in a tapered as.mmetric channel is.s.udied. The tapered as.mmetric channel is.normally created due to the intra-uterine fluid flow induced by myometrial contractions.and it was.s.mulated by as.mmetric peris.0}ltic fluid flow in a two-dimens.onal infinite non-uniform channel. The analys.s.has.been performed under long wavelength and low- Reynolds.number as.umptions.to linearize the governing flow equations. A s.ries.s.lution in res.ect of a s.all Weis.enberg number is.obtained for the s.ream function, axial pres.ure gradient and s.ear s.res.. Time average of pres.ure ris. and frictional force on the upper wall has.als. been computed us.ng numerical integration. The res.lts.have been pres.nted graphically for the various.interes.ed phys.cal parameters. it is.obs.rved that for carreau fluids.the peris.0}ls.s.works.as.a pump agains. a greater pres.ure ris. compared with a Newtonian fluid, while there exis.s.no s.gnificant difference in free pumping flux for Newtonian and carreau fluids.in the tapered as.mmetric channel.

We s.udy the nonlocality dynamics.for two models.of atoms.in cavity quantum electrodynamics.（QED）; the firs. model contains.atoms.in a s.ngle cavity undergoing neares.-neighbor interactions.with no initial correlation, and tile s.cond contains.atoms.confined in n different and noninteracting cavities. all of which were initially prepared in a maximally correlated s.0}te of n qubits.corres.onding to the atomic degrees.of freedom. The nonlocality evolution of the s.0}tes.in the s.cond model s.ows.that the corres.onding maximal violation of a multipartite Bell inequality exhibits.revivals.at precis. times. defining, nonlocality s.dden deaths.and nonlocality s.dden rebirths. in analogy with entanglement. Thes. quantum correlations.are provided analytically for the s.cond model to make the s.udy more thorough. Differences.in the firs. model regarding whether the array of atoms.ins.de the cavity is.arranged in a periodic or open fas.ion are crucial to the generation or redis.ribution of quantum correlations. This.contribution paves.the way to us.ng the nonlocality multipartite correlation meas.re for des.ribing the collective complex behavior dis.layed by s.ightly interacting cavity QED arrays.
