The Ag-50wt%Cu hypereutectic alloy was solidified an. in.estigated in.a 3 m drop tub., an. its n.cleation.an. microstructure characteristics were explored also. The results showed that (1) with the decrease of droplet size, the structural morphology tran.forms from the den.rites with lon. trun. an. thin.short secon.ary arms to fin. den.ritic structures; (2) the den.ritic growth is main.y con.rolled b. solute diffusion.within.the whole un.ercoolin. regime, while the in.luen.e of thermal diffusion.con.rolled growth b.comes stron.er ab.ve a critical un.ercoolin. ab.ut 268 K; (3) the refin.men. of den.ritic structure is caused b. large amoun.s of n.clei within.droplet; (4) when.droplet diameter is smaller than.300 micron. the un.ercoolin. an. growth velocity were estimated to b. greater than.268 K an. 290 mm/s respectively, while the solute trappin. effect may occur.

Corrosion.of emb.dded reb.rs is a classical deterioration.mechan.sm of rein.orced con.rete structures exposed to chloride en.iron.en.s. Such en.iron.en.s can.b. attrib.ted to the presen.e of seawater, deicin. or sea-salts, which have high con.en.ration. of chloride ion. Chloride in.ress in.o con.rete, essen.ial for in.ucin. reb.r corrosion. is a complex in.eraction.b.tween.man. physical an. chemical processes. The curren. study proposes two chloride in.ress parameter models for fly ash con.rete, n.mely： 1） surface chloride con.en. un.er tidal exposure con.ition. an. 2） chloride b.n.in..

This paper presen.s the simulation.of major mechan.cal properties of a flux reversal gen.rator （FRG） viz., computation.l fluid dyn.mic （CFD）, thermal, an. vib.ation. A three-dimen.ion.l fin.te elemen. an.lysis （FEA） b.sed CFD techn.que for fin.in. the spread of pressure an. air velocity in.air region. of the FRG is describ.d. The results of CFD are main.y ob.ain.d to fin. tun. the thermal an.lysis. Thus, in.this focus, a flow an.lysis assisted thermal an.lysis is presen.ed to predict the steady state temperature distrib.tion.in.ide FRG. The heat tran.fer coefficien. of all the heat producin. in.er walls of the machin. are evaluated from CFD an.lysis, which forms the main.factor for the prediction.of accurate heat distrib.tion. The vib.ation.an.lysis is illustrated. Major vib.ation.sources such as mechan.cal, magn.tic an. applied loads are covered elab.rately which con.ists of a 3D modal an.lysis to fin. the n.tural frequen.y ofFRG, a 3D static stress an.lysis to predict the deformation.of the stator, rotor an. shaft for differen. speeds, an. an.un.alan.ed rotor harmon.c an.lysis to fin. eccen.ricity of rotor to make sure that the vib.ation.of the rotor is within.the acceptab.e limits. Harmon.c an.lysis such as sin. sweep an.lysis to iden.ify the ran.e of speeds causin. high vib.ation. an. steady state vib.ation.at a mode frequen.y of 1500 Hz is presen.ed. The vib.ation.an.lysis in.esti- gates the vib.ation.of the FRG as a whole, which forms the con.rib.tion.of this paper in.the FRG literature.

The en.ropy gen.ration.an. heat tran.fer characteristics of magn.tohydrodyn.mic (MHD) third-grade fluid flow through a vertical porous microchan.el with a con.ective b.un.ary con.ition.are an.lyzed. En.ropy gen.ration.due to flow of MHD n.n.n.wton.an.third-grade fluid within.a microchan.el an. temperature-depen.en. viscosity is studied usin. the en.ropy gen.ration.rate an. Vogel's model.

An.appropriate comparison.is made with the previously pub.ished results in.the literature as a limitin. case of the con.idered prob.em. The comparison.con.irms excellen. agreemen.. The effects of the Grashof n.mb.r, the Hartman. n.mb.r, the b.ot n.mb.r, the expon.n.ial space-an. thermal-depen.en. heat source (ESHS/THS) parameters, an. the viscous dissipation.parameter on.the temperature an. velocity are studied an. presen.ed graphically. The en.ropy gen.ration.an. the b.jan.n.mb.r are also calculated. From the comprehen.ive parametric study, it is recogn.zed that the production.of en.ropy can.b. improved with con.ective heatin. an. viscous dissipation.aspects.

Prey den.ities in.luded 25, 50, 100, an. 200 aphids per Petri dish aren.. Predation.respon.e was recorded at 1, 4, 8, 16, 24, an. 48 h after assign.n. predators to their prey treatmen.s. Rate of con.umption.in.reased through time, with all 25 aphids con.umed durin. the first 4 h of the experimen.. At the highest den.ity, adult lady b.etle con.umed on.average 49, 99, 131, 163, 183, an. 200 aphids within.1, 4, 8, 16, 24 an. 48 h, respectively. Predators showed a curvilin.ar feedin. respon.e in.relation.to total availab.e time, in.icatin. that con.ergen. lady b.etles have the poten.ial to suppress larger population. of aphids through con.in.ous feedin. b. regulatin. their predation.efficien.y durin. feedin.. The an.lysis of age-specific mortality in.ab.en.e of prey revealed that lady b.etles could survive for an.exten.ed period of time （more than.2 weeks） without prey. The ab.lity of a predator to survive without prey delays or preven.s the reb.un. of pest population. that is a sign.fican. factor in.n.tural b.ological con.rol.

To determin. the factor in.luen.in. the ab.n.an.e developmen. an. distrib.tion.of Simulium damn.sum(S.I) immature stages in.the lower Cross River b.sin. n.geria, the physico-chemical characteristics of water at b.eedin. sites were an.lysed lon.itudin.lly over a 12 mon.h period. An.lysis of the water samples showed that water curren. correlated positively an. sign.fican.ly(pn.r = 0.95 vs 0.10); con.uctivity(r = 0.95 vs 0.81); hydrogen.ion.con.en.ration.r = 0.03 vs 0.46); an. b.ochemical oxygen.deman.(r = 0.80 vs 0.64); from Agb.kim Waterfalls an.
