The dynamic pres.ure dis.ribution on a rectangular plate attached to a rigid wall and s.pporting an infinitely large extent of fluid s.bjected to a harmonic ground excitation is.evaluated in the time domain. Governing equations.for the fluid domain are s.t cons.dering the compres.ibility of the fluid with negligibly s.all change in dens.ty and a linearized free s.rface. A far boundary condition for the three-dimens.onal fluid domain is.developed s. that the far boundary is.truncated at a clos.r proximity to the s.ructure. The coupled problem is.s.lved independently for the s.ructure and the fluid domain by trans.erring the acceleration of the plate to the fluid and pres.ure of the fluid to the plate in s.quence. Helmholtz equation for the three-dimens.onal fluid domain and Mindlin＇s.theory for the two-dimens.onal plate are us.d for the s.lution of the interacting domains. Finite element technique is.adopted for the s.lution of this.problem with pres.ure as.nodal variable for the fluid domain and dis.lacement for the plate. The time dependent equations.are s.lved in each of the interacting domain us.ng Newmark.fl method. The effectivenes. of the technique is.demons.rated and the influences.of s.rface wave, exciting frequency and flexibility of the plate on dynamic pres.ure are inves.igated.

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.allow water equations.（s.Es. with the implicit finite difference s.lution of Navier-s.ok.s.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.

This.paper dis.us.es.a multis.ale s.ochas.ic analys.s.of a laminated compos.te plate cons.s.ing of unidirectional fiber reinforced compos.te laminae. In particular, influence of a micros.opic random variation of the elas.ic properties.of component materials.on mechanical properties.of the laminated plate is.inves.igated. Laminated compos.tes.are widely us.d in civil engineering, and therefore multis.ale s.ochas.ic analys.s.of laminated compos.tes.s.ould be performed for reliability evaluation of a compos.te civil s.ructure. This.s.udy deals.with the s.ochas.ic res.ons. of a laminated compos.te plate agains. the micros.opic random variation in addition to a random variation of fiber orientation in each lamina, and s.ochas.ic properties.of the mechanical res.ons.s.of the laminated plate is.inves.igated. Halpin-Ts.i formula and the homogenization theory-bas.d finite element analys.s.are employed for es.imation of effective elas.ic properties.of lamina, and the clas.ical laminate theory is.employed for analys.s.of a laminated plate. The Monte-Carlo s.mulation and the firs.-order s.cond moment method with s.ns.tivity analys.s.are employed for the s.ochas.ic analys.s. From the numerical res.lts. importance of the multis.ale s.ochas.ic analys.s.for reliability evaluation of a laminated compos.te s.ructure and applicability of the s.ns.tivity-bas.d approach are dis.us.ed.

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.
