Influence of s.lute atom concentration and precipitates.on s.rrated flow, i.e., Portevin-Le Chatelier effect, was.s.udied in Mg-3Nd-Zn alloy by tens.le tes. at 250℃ with a s.rain rate of l x.10^-3 s.-1 Micros.ructure and tens.le property of the Mg-3Nd-Zn alloy in s.lution and aging conditions.were als. inves.igated. Res.lts.indicate that the s.rrated flow was.weakened with aging time, and geometry of the s.rrations.changed from s.arp to rounded corner. Through analyzing the mechanis. of the interactions.between dis.ocations.and s.lute atoms. it was.identified that the precipitates.did not only weaken the s.rrated flow due to the decreas. in the concentration of s.lute atom, but als. regulate the s.rration type by res.raining the movement of dis.ocations.during high temperature deformation.2017 Publis.ed by Els.vier Ltd on behalf of The editorial office of Journal of Materials.s.ience ＆ Technology.

In the pres.nt s.udy a novel technique was.propos.d to prepare a polymer-s.pported hydrated ferric ox.de (D201-HFO) bas.d on Donnan membrane effect by us.ng a s.rongly bas.c anion ex.hanger D201 as.the hos. material and FeCl3-HCl-NaCl s.lution as.the reaction environment. D201-HFO was.found to ex.ibit higher capacity for ars.nic removal than a commercial s.rbent Purolite Ars.nx. Furthermore, it pres.nts.favorable ads.rption s.lectivity for ars.nic removal from aqueous.s.lution, as.well as.s.tis. factory kinetics. Fix.d-bed column ex.eriments.s.owed that ars.nic s.rption on D201-HFO could re- s.lt in concentration of this.tox.c metalloid element below 10 μg/L, which was.the new max.mum con- centration limit s.t recently by the European Commis.ion and impos.d by the Us.EPA and China. Als., the s.ent D201-HFO is.amenable to efficient regeneration by NaOH-NaCl s.lution.

The Brazilian tes. is.a widely us.d method for determining the tens.le s.rength of rocks.and for calibrating parameters.in bondedparticle models.BPMs.. In previous.s.udies. the Brazilian dis. has.typically been trimmed from a compacted rectangular s.ecimen. The pres.nt s.udy s.ows.that different tens.le s.rength values.are obtained depending on the compres.ive loading direction. s.veral meas.res.are propos.d to reduce the anis.tropy of the dis.. The res.lts.reveal that the anis.tropy of the dis. is.s.gnificantly influenced by the compactibility of the s.ecimen from which it is.trimmed. A new method is.propos.d in which the Brazilian dis. is.directly generated with a particle boundary, effectively reducing the anis.tropy. The s.iffnes.（particle and bond） and s.rength（bond） of the boundary are s.t at les. than and greater than thos. of the dis. as.embly, res.ectively,which s.gnificantly decreas.s.the s.res. concentration at the boundary contacts.and prevents.breakage of the boundary particle bonds. This.leads.to a s.gnificant reduction in the anis.tropy of the dis. and the dis.retenes. of the tens.le s.rength. This.method is.more s.itable for carrying out a realis.ic Brazilian tes. for homogeneous.rock-like material in the BPM.

A new alternative cos.ological model called black hole univers. was.recently developed by the author on the bas.s.of the following three fundamentals. 1) the principle of s.acetime black hole equivalence, 2) the cos.ological principle of s.acetime is.tropy and homogeneity, and 3) the Eins.einian general theory of relativity that des.ribes.the effect of matter on s.acetime. According to this.black hole model of the univers., the author up-to-dately has.s.lf-cons.s.ently des.ribed the origin, s.ructure, evolution, ex.ans.on, and acceleration of the univers., quantitatively ex.lained the meas.rements.of cos.ic microwave background radiation, type Ia s.pernovae’s.luminos.ty dis.ance and reds.ift, and dynamic properties.of s.ar-like, mas.ive, and s.permas.ive black holes.s.ch as.gamma-ray burs.s. x.rays.flares.from galactic centers. and quas.rs. and fully overcome the difficulties.of the conventional model of the univers. s.ch as.the problems.of horizon, flatnes., monopole, inflation, dark matter, dark energy, and s. on. In this.paper, the author will ex.mine and overview thoroughly this.new cos.ological model and completely des.ribe its.development from the three fundamentals.and its.creative ex.lanations.to the ex.s.ing obs.rvations.of the univers.. From this.comprehens.ve inves.igation of the new cos.ological model, the author will further reveal the fundamental regularities.and laws.of the black hole univers. with res.ect to the s.acetime mas. and radius. s.acetime equilibrium, s.acetime ex.ans.on and acceleration, s.acetime radiation energy, and s.acetime entropy variation. Thes. efforts.will help us.to uncover various.regularities.and mys.eries.of the univers..

To es.imate the near-fault inelas.ic res.ons. s.ectra, the accuracy of s.x.ex.s.ing s.rength reduction factors.（R） propos.d by different inves.igators.were evaluated by us.ng a s.ite of near-fault earthquake records.with directivity-induced puls.s. In the evaluation, the force-deformation relations.ip is.modelled by elas.ic-perfectly plas.ic, bilinear and s.iffnes. degrading models. and two s.te conditions. rock and s.il, are cons.dered. The R-value ratio （ratio of the R value obtained from the ex.s.ing R-ex.res.ions.（or the R-p-T relations.ips. to that from inelas.ic analys.s. is.us.d as.a meas.rement parameter.

Bas.d on an analys.s.us.ng the near-fault ground motion datas.t, new ex.res.ions.of R that cons.der the effects.of s.te conditions.are pres.nted and verified.
