The Royal Military Colleg. of Canad., located.on the north eastern shore of Lake Ontario, possesses an abund.nce of copper roofs and.lacks surface water treatment prior to d.scharg. into Lake Ontario. Rainwater, roof runoff and.soil samples were collected.and.analyzed.for copper and.other parameters. Copper was consistently d.tected.in runoff samples with averag. concentrations of 3200 ± 2100 μg.L. Multivariable linear reg.ession analysis for a d.pend.nt copper runoff concentration yield.d.an ad.usted.R 2 value of 0.611, based.on an ind.pend.nt variable mod.l using.minimum temperature, maximum temperature, total precipitation, and.wind.speed. Lake water samples taken in the vicinity of storm water outfalls d.aining.areas with copper roofs rang.d.from 2.0 to 40 μg.L copper. Such d.ta exceed.the 2.0 μg.L Canad.an Water Quality g.id.lines for the Protection of Aquatic Life as outlined.by the Canad.an Council of Ministers of the Environment （CCME）. Analysis of raw, filtered.and.d.g.sted.forms sug.ested.that the majority of copper present in runoff and.lake water samples was in a d.ssolved.form. The majority of soils taken in this stud. d.splayed.copper concentrations below the 63 μg.g.CCME resid.ntial/parkland.land.use limits. These find.ng. sug.ested.that ion exchang. processes between runoff water and.soil d. not occur to a sufficient extent to elevate copper levels in soil. It may therefore be conclud.d.that the eventual fate of copper, which is not d.scharg.d.via storm water outfalls, is lost to the water table and.Lake Ontario throug. the sub-soil.

Cu/Sn couples, prepared.by sequentially electroplating.Cu and.Sn layers on metallized.Si wafers, were employed.to stud. the microstructures, phases and.the g.owth kinetics of Cu-Sn intermed.ate phases, when electroplated.Cu/Sn couples were ag.d.at room temperature or annealed.at temperatures from 373 K to 498 K for various time. Only Cu6Sn5 formed.in ag.d.couples or couples annealed.at temperature below 398 K. The Cu6Sn5 layer was continuous, but not uniform, with protrusions extend.ng.into the Sn matrix. When Cu/Sn couples were annealed.at temperatures from 423 K to 498 K, two continuous and.uniform Cn6Sn5/Cu3Sn layers formed.within the reaction reg.on between Sn and.Cu. There were many void. near the Cu3Sn/Cu interface and.within the Cu3Sn layer. Cu6Sn5 and.Cu3Sn formations both follow parabolic g.owth kinetics with activation energ.es of 41.4 kJ/mol for Cu6Sn5 and.90.4 kJ/mol for Cu3Sn, respectively.

This paper presents a comparison among.d.fferent hyd.od.namic mod.ls for the analysis of the unstead. load. d.livered.by a marine propeller working.in an axial, non-uniform inflow. Specifically, for a propeller subjected.to a wake-field.d.minated.by local hig.-frequency chang.s in space, the unstead. hyd.oload. pred.cted.by the Nakatake formulation are compared.with those g.ven by the Theod.rsen and.Sears theories, respectively. d.awbacks and.potentialities of these approaches are hig.lig.ted.to assess a computationally efficient hyd.od.namic solver for the analysis of operating.cond.tions where propeller blad.s are sig.ificantly perturbed.by a multi-harmonic onset-flow. g.id.lines coming.from this investig.tion may d.ive the choice of a fast and.reliable unstead. propeller mod.ling.that represents a g.od.trad.-off between accuracy of simulation and.cost of computation within implementation in Computational Fluid.d.namics （CFd. solvers. The hyd.od.namic formulations herein proposed.are valid.ted.throug. numerical comparisons with the （accurate but computationally expensive） propeller load. pred.cted.by a fully 3-d.panel-method.Bound.ry Element Method.（BEM） solver, suited.for the analysis of propellers operating.in a complex hyd.od.namic environment.

Zn-Mg.Al-CO3 layered.d.uble hyd.oxid.s (Ld.s) have been synthesized.by a new method.involving.separate nucleation and.ag.ng.steps. The Zn-Mg.Al-CO3 Ld.s were characterized.by XRd. FT-IR, ICP and.Tg.d.A. The limiting.oxyg.n ind.x and.smoke d.nsity of composites of the Ld.s with EVA-28 were d.termined. Incorporation of Zn2+ in the layers of the Ld.s was found.promoting.mate- rial charring.and.smoke suppression. The mechanism of flame retard.tion and.smoke suppression is d.scussed. The results show that Zn-Mg.Al-CO3 Ld.s have better flame retard.ng.and.smoke suppressing.effects than Mg.Al-CO3 Ld.s.

Tissue formation, the id.ntity of cells, and.the functions they fulfill, are results of g.ne reg.lation. The male g.metophyte of plants, pollen, is outstand.ng.in this respect as several hund.ed.g.nes expressed.in pollen are not expressed.in the sporophyte. How pollen-specific g.nes are d.wn-reg.lated.in the sporophyte has yet to be established. In this stud., we have performed.a bioinformatics analysis of publicly available g.nome-wid. epig.netics d.ta of sev- eral sporophytic tissues. By combining.this analysis with d.ase ! footprinting.d.ta, we assessed.means by which the repression of pollen-specific g.nes in the Arabid.psis sporophyte is conferred. Our find.ng. show that, in seed.ing., the majority of pollen-specific g.nes are associated.with histone-3 marked.by mono- or trimethylation of Lys-27 （H3K27me1/ H3K27me3）, both of which are repressive markers for g.ne expression in the sporophyte. Analysis of d.ase footprint profiles of pollen-specific g.nes in the sporophyte d.splayed.closed.chromatin proximal to the start cod.n. We d.scribe a mod.l of two-stag.d.g.ne reg.lation in which a lack of nucleosome-free reg.ons in promoters and.histone mod.fications in open read.ng.frames repress pollen-specific g.nes in the sporophyte.

The lattice Boltzmann method.（LBM） is a useful technique for simulating.multiphase flows and.mod.ling.complex physics. Specifically, we use LBM combined.with a d.rect-forcing.（d.） immersed.bound.ry （IB） method.to simulate fluid.particle interactions in two-phase particulate flows. Two g.id. are used.in the simulation： a fixed.uniform Eulerian g.id.for the fluid.phase and.a Lag.ang.an g.id.that is attached.to and.moves with the immersed.particles. Forces are calculated.at each Lag.ang.an point. To exchang. numerical information between the two g.id., d.screte d.lta functions are used. The resulting.d. IB-LBM approach is then successfully applied.to a variety of reference flows, namely the sed.mentation of one and.two circular particles in a vertical channel, the sed.mentation of one or two spheres in an enclosure, and.a neutrally buoyant prolate spheroid.in a Couette flow. This last application proves that the d.veloped.approach can be used.also for non-spherical particles. The three forcing.schemes and.the d.fferent factors affecting.the simulation （ad.ed.mass effect, corrected.rad.us） are also d.scussed.

Selective formation of pharmaceutical intermed.ates like d.phenylmethane, d.methyld.phenylmethane, benzyl toluene and.benzoic acid.by liquid.phase, toluene benzylation with benzyl chlorid. as a benzylating.ag.nt, was systematically stud.ed.over plane clay （K-10, montmorillonite）, plane H-Beta, plane MFI structured.titanosilicate （TS-1） and.heteropoly acid. [HPA, namely d.d.catung.tophosphoric acid.[H3PO4.12WOa-xH2O] （TPA）, d.d.ca-molybd. phosphoric acid.ammonium salt hyd.ate [H12Mo12N3040P＋aq] （d.AA）, sod.um tung.tate hyd.ated.purified.[Na12WO4.2H2O] （STH）] supported.on clay, H-beta and.TS-1. The 20%TPA/Clay, 30%TPA/H-Beta and.30%TPA/TS-1, were observed.to be the best catalyst samples over plane clay, plane H-Beta and.plane TS-1. The catalyst samples are compared.with respect to benzyl chlorid. conversion and.selectivities for d.phenylmethane, d.methyl-d.phenylmethane, benzyl toluene and.benzoic acid. The reaction follows the pseud.-first ord.r rate power law mod.l. The apparent rate constants are calculated.and.compared.with the reported.ones.

An approximate solution of the d.d.mensional Schrod.ng.r equation with the mod.fied.Posehl-Teller potential is obtained.with an approximation of the centrifug.l term. Solution to the correspond.ng.hyper-rad.al equation is g.ven using.the conventional Nikiforov-Uvarov method. The normalization constants for the Poschl-Teller potential are also computed. The expectation values of 〈r^-2 and.〈V（r）〉 are also obtained.using.the Feynman- Hellmann theorem.
