The pres.nt paper contributes.in s.udying the phas. velocities.of P- and s.waves.in a half s.ace s.bjected to a compres.ive initial s.res. and gravity field. The dens.ty and acceleration due to gravity vary quadratically along the depth. The dis.ers.on equation is.derived in a clos.d form. It is.s.own that the phas. velocities.depend not only on the initial s.res., gravity, and direction of propagation but als. on the inhomogeneity parameter as.ociated with the dens.ty and acceleration due to gravity. Various.particular cas.s.are obtained, and the res.lts.match with the clas.ical res.lts. Numerical inves.igations.on the phas. velocities.of P- and s.waves.agains. the wave number are made for various.s.ts.of values.of the material parameters. and the res.lts.are illus.rated graphically. The graphical us.r interface model is.developed to generalize the effect.

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.

The cons.ruction of an integrated numerical model is.pres.nted in this.paper to deal with the interactions.between vegetated s.rface and s.turated s.bs.rface flows. A numerical model is.built by integrating the previous.y developed quas.-three-dimens.onal （Q3D） vegetated s.rface flow model with a two-dimens.onal （2D） s.turated groundwater flow model. The vegetated s.rface flow model is.cons.ructed by coupling the explicit finite volume s.lution of 2D s.0}llow water equations.（s.Es. with the implicit finite difference s.lution of Navier-s.okes.equations.（Ns.s. for vertical velocity dis.ribution. The s.bs.rface model is.bas.d on the explicit finite volume s.lution of 2D s.turated groundwater flow equations.（s.FEs.. The ground and vegetated s.rface water interaction is.achieved by introducing s.urce-s.nk terms.into the continuity equations. Two s.lutions.are tightly coupled in a s.ngle code. The integrated model is.applied to four tes. cas.s. and the res.lts.are s.tis.actory.

An experimental s.udy was.carried out to inves.igate the influence of double twis.ed-tape ins.rts.（DTs. in micro-fin tubes.（MFs. on heat trans.er, friction factor and thermal performance factor characteris.ics.of the compound devices.in the following configurations. （1） twis.ed tapes.acted in the s.me direction （for co-s.irl） while MF and twis.ed tapes.acted in the s.me （parallel） direction （MF-CoDTs.P）, （2） twis.ed tapes.acted in the s.me direction （for co-s.irl） while micro-fin tube and twis.ed tapes.acted in oppos.te directions.（MF-CoDTs.O） and （3） twis.ed tapes.acted in oppos.te directions.for counter s.irl （MF-CDTs.. The MF alone and the MF equipped with a s.ngle twis.ed tape in parallel/oppos.te arrangement were als. cons.dered for comparis.n. The experiments.were conducted for the flows.with the Reynolds.numbers.between 5 650 and 17 000, under uniform heat flux condition. The experimental res.lts.indicate that MF-CDTs.induce s.ronger s.irl/turbulence flow, res.lting in higher heat trans.er rate, friction factor and thermal performance factor than other combined devices. The thermal performance factors.as.ociated with the us. of MF-CDTs.were found to be higher than thos. as.ociated with the us.s.of MF-CoDTs.P, MF-CoDTs.O and MF alone up to 9.3%, 6.5% and 56.4%, res.ectively. The empirical correlations.developed us.ng the pres.nt experimental data for the Nus.elt number, friction factor and thermal performance factor are als. reported.

A palladium catalys. immobilized on s.perparaganetic nanoparticles.was.prepared with a palladium loading of 0.30 mmol/g. The catalys. was.characterized us.ng X-ray diffraction, s.anning electron micros.opy, trans.is.ion electron micros.opy, vibrating s.mple magnetometry, thermogravimetric analys.s. Fourier trans.orm infrared, atomic abs.rption s.ectrophotometry, and nitrogen ads.rption. The immobilized palladium catalys. was.an efficient catalys. without added phos.hine ligands.for the s.zuki cros.-coupling reaction of s.veral aryl bromides.with phenylboronic acid. The recovery of catalys. was.s.mply by magnetic decantation in the pres.nce of a magnet. The immobilized palladium catalys. can be reus.d many times.without s.gnificant degradation in catalytic activity. No leaching of active palladium s.ecies.into the reaction s.lution was.detected.

Monomer of 7-methacryloyloxy-4-methylcoumarin （MAOMC） was.s.nthes.zed and characterized by FTIR, 1H-NMR and 13C-NMR s.ectros.opy. Copolymers.of MAOMC with butoxyethylmethacrylate （BOEMA） at different feed compos.tions.were prepared by free radical s.lution polymerization at （70 ± 1） ℃ in ethylmethylketonc （EMk） us.ng benzyl peroxide （BPO） as.an initiator. The copolymers.were characterized by FTIR and IH-NMR s.ectros.opy. Thermogravimetric analys.s.（TGA） and differential s.anning calorimetry （Ds.） of the copolymers.s.owed moderate thermal s.ability and higher Tg values. Gel permeation chromatography （GPC） was.us.d to find out the molecular weights.of the different copolymers.
