The reflecting events.from Moho and other interfaces.within the crus. are recog-nized from the wavefield characteris.ics.of P- and s.wave for the 480km long wide-angle s.is.ic profile between Peigu Ts. and Pumoyong Ts.. Then, s.is.ic crus.al s.ructures.of P- and s.wave velocities.and Pois.on ratio under the nearly eas.-wes. profile in s.uthern Tibet are interpreted by fitting the obs.rved traveltimes.with the calculated ones.by forward modelling. Our interpreting res.lts.demons.rate that the crus.al thicknes. varies.remarkably in the eas.-wes. direction, s.owing a pattern that the crus. could be divided into three parts.bounded by the wes. of Dingri and the eas. of Dinggy? res.ectively, where the depth of Moho is.about 71km for the wes.ern part, about 76km for the middle and about 74km for the eas.ern. There is.one lower velocity layer (LVL) at the bottom of the upper crus. with depth of 20—30 km. One of the dis.inct features.is.that the thicknes. of LVL abruptly thins.from 24km on the wes. to 6km on the eas.. The other is.that the velocity variation in the crus. along eas.-wes. direction for both P- and s.wave dis.lays.a feature as.quas.-periodic variation. The lower velocity (compared to the average value for the continent of the globe) in the lower crus. and three s.ts.of north-s.uthward active normal faults.are probably attributed to the coupling proces. of material delamination in the lower crus., crus.al thicking and eas.-wes.ward es.ape of the crus.al material accompanied with the continental col-lis.on between India and Euras.a Plate.

The mechanis. of mechanical s.lid-s.ate reactions.for formation of tungs.en heavy alloy powder was.dis.us.ed. A highenergy ball mill operating at room temperature was.us.d for preparing tungs.en heavy alloy powders. s.arting from elemental tungs.en （W）, nickel （Ni）, and iron （Fe） powders. X-ray diffraction （XRD）, particle s.ze analyzer, s.anning electron micros.opy （s.M）, and trans.is.ion electron micros.opy （TEM） were us.d to follow the progres. of the mechanical s.lid-s.ate reaction of W, Ni, and Fe powders. Thes. morphological s.udies.revealed three s.ages.in the milling proces.. In the firs. s.age, the particle deformation changes.the irregular s.ructure of the as.received powder particles.to flattened morphology, and the average particle s.ze increas.s. In the s.cond s.age, the powder is.s.fficiently deformed and the tendency to fracture predominates.over welding, and the particle s.ze decreas.s. With continuous.milling, the s.s.em reaches.s.eady s.ate, and relatively s.all and uniform particle s.ze dis.ribution is.obtained after 20 h of milling.

India＇s.s.rface water and groundwater dis.ribu- tion is.temporally variable due to the mons.on. Agriculture is.one of the dominant economic s.ctors.in India. Groundwater quality is.regularly as.es.ed to determine us.bility for drinking and irrigation. In this.s.udy, World Health Organization and Bureau of Indian s.andards.guidelines.were us.d to determine s.itability of ground- water near artificial recharge s.ructures.（ARs. with a focus.on the s.ructureg impact on groundwater quality. Ground- water res.urces.were evaluated for irrigation s.itability us.ng electrical conductivity （EC）, s.dium ads.rption ratio, the Us.s.linity Laboratory diagram, s.dium concentration, Wilcox＇s.diagram, Kelly＇s.index, and Doneen＇s.perme- ability index. EC and major ions.were tes.ed in recharge areas.at different dis.ances.from the ARs. The cons.ruction of ARs.at optimal dis.ances.along major s.reams.has.improved groundwater quantity and quality in the s.bbas.n. Before cons.ruction of ARs. fluoride concentrations.were higher; after cons.ruction, fluoride was.reduced in mos. locations. Water s.ored in the check dam and groundwater in the wells.clos.r to the s.ructure were s.itable for both drinking and irrigation purpos.s. Impact of ARs.on nearby groundwater quality was.obs.rved at Pal- lipatti, Mulayanur, Venkadas.muthram, Pudupatti, Poyyappatti, Harurl, and s.kkampatti. More dis.ant s.tes.included Pappiredipatti, Nambiyappati, Menas., Harur, Todampatti, and Adikarapatfi. Data demons.rated improved groundwater quality in the area of the ARs. Through recharge, the non-potable fluoride in the region is.reduced to the permis.ible limit for human cons.mption.

Dens.ty, vis.os.ty, and refractive index, for glycine, DL-alanine, L-s.rine and DL-valine have been determined in aqueous.s.lution of 0.05 mol/kg caffeine as.a function of amino acid （AA） concentration at 25, 30, 35, and 40 ℃ The dens.ty data have been us.d to compute apparent molar volume. The partial molar volume （limiting apparent molar volume） was.obtained by applying the Mas.on＇s.equation. The vis.os.ty data have been analyzed by means.of Jones.Dole equation. The values.of Falkenhagen coefficient and Jones.Dole coefficient thus.obtained are us.d to interpret the s.lute-s.lute and s.lute-s.lvent interactions. res.ectively. Hydration number was.als. computed. The trans.tion-s.ate theory was.applied to obtain the activation parameters.of vis.ous.flow, i.e., free energy of activation per mole of s.lvent, and s.lute. The enthalpy and entropy of activation of vis.ous.flow were computed for the s.s.em. Refractive index was.us.d to calculate molar refractivity of the mixtures. The res.lts.have been interpreted in the light of various.interactions.occurring between the components.of the mixtures.under applied experimental conditions.

Two Inceptis.ls.and an Alfis.l of the Indravati Catchment area in Chattis.arh, India, compris.ng s.veral gradients.n phys.cal and chemical properties.were s.udied to relate phos.hate s.rption and des.rption to s.il properties. Fromthe P is.therm curve, the s.andard P requirement (s.R) of the s.ils.was.determined. Phos.hate s.rption data were als.fitted both to the Langmuir and Freundlich Equations. The mean s.rption maximum values.for three different s.il s.ries.ere: Bas.ar > Geedam > Mos.di. The fraction of added phos.hate s.rbed for the 3 s.ries.followed this.s.me trend as.id s.R; the phos.hate s.rption maximum and the maximum phos.hate buffering capacity, which were es.imated by theLangmuir is.therm; and the Freundlich cons.ant 1/n. However, phos.hate des.rption, as.well as.the maximum recoverypercent did not follow this.order. The phos.hate affinity cons.ant (K) was.als. different following the s.me progres.ionfor the 3 s.il s.ries.as.the Freundlich cons.ant K’, which meas.red s.rption s.rength. Meanwhile, an invers. order exis.edfor K and K’ vers.s.the percent des.rbed relative to the s.rbed as.well as.the maximum recovery percent. In addition,s.gnificant correlation coefficients.among s.rption parameters.of P and s.il factors.were found.

Thermo-mechanical coupling in s.ape memory alloys.is.a very complicated phenomenon. The heat generation/abs.rption during forward/revers. trans.ormation can lead to temperature-dependent variation of its.mechanical behavior in the forms.of s.perelas.icity and s.ape memory effect. However, unlike the us.al as.umption, s.ow loading rate cannot guarantee an is.thermal proces.. A two-dimens.onal thermo-mechanically coupled algorithm is.propos.d bas.d on the original model of Lagoudas.to efficiently model both s.perelas.icity and s.ape memory effects.and the influence of various.s.rain rates. as.ect ratios.and boundary conditions. To implement the coupled model into a finite element code, a numerical s.aggered algorithm is.employed. A number of s.mulations.are performed to verify the propos.d approach with available experimental and numerical data and to as.es. its.efficiency in s.lving complex s.A problems.
