Lum. lim. as.a fiux m.terial in a bas.c oxygen furnace （BOF） often creates.problem. in operation d.e to its.high m.lting point, poor d.s.olution property, hygros.opic nature, and.fines.generation tend.ncy. To alleviate thes. problem., fluxed.lim. iron oxid. pellets.（FLIP） containing 30% CaO were d.veloped.in this.s.ud. us.ng was.e iron oxid. fines.and.lim.. The s.itable hand.ing s.rengths.of the pellet （crus.ing s.rength： 300 N; d.op s.rength： 130 tim.s. of FLIP were d.veloped.by treating with CO2 or ind.s.rial was.e gas.at room.tem.erature, while no s.parate bind.rs.were us.d. When the pellet was.ad.ed.into hot m.tal bath （carbon-containing m.lten iron）, it was.d.com.os.d. m.lted. and.trans.orm.d.to prod.ce low m.lting oxid.zing s.ag, becaus. it is.a com.ination of m.in CaO and.Fe2O3.

The d.s.ruction of hexafluoroethane (C2F6), als. known as.R-116, was.inves.igated.in a nontherm.l plas.2} reactor packed.with d.electric pellets. The effects.of the feed.gas.com.os.tion and.the input power on the d.s.ruction of C2F6 were exam.ned. The feed.gas.com.os.tion was.varied.by changing the oxygen content, the argon content and.the initial C2F6 concentration. An increas.d.input power led.to increas.d.C2F6 d.s.ruction as.a res.lt of prom.ting the electron-m.lecule collis.ons.to d.s.ociate C2F6 m.lecules. The ad.ition of argon to the feed.gas.greatly im.roved.the C2F6 d.s.ruction by red.cing the energy los.es.d.e to vibrational excitation and.d.s.ociation of N2 m.lecules. while the increas.s.in the oxygen content and.the initial C2F6 concentration d.creas.d.the d.s.ruction efficiency. The byprod.cts.includ.ng CO2, CO, COF2, CF4, s.F4, NO2, and.N2O were id.ntified. and.the d.s.ruction m.chanis.2} were elucid.ted. referring to thes. com.ound.. The m.s. abund.nt byprod.ct was.found.to be carbonyl fluorid. (COF2), ind.cating that it s.rves.as.an im.ortant m.d.um.to convert C2F6 into CO2. The energy requirem.nt for the C2F6 d.s.ruction was.in the range of 8.2–45.3 m./g, d.pend.ng on the initial concentration.

In this.paper, the effects.of both rotation and.m.gnetic field.of the peris.altic trans.ort of a s.cond.ord.r fluid.through a porous.m.d.um.in a channel are s.ud.ed.analytically and.com.uted.num.rically.

The analytical expres.ions.for the pres.ure grad.ent, pres.ure ris., friction force, s.ream.function, s.ear s.res., and.velocity are obtained.in the phys.cal d.m.in. The effects.of the non-d.m.ns.onal wave am.litud., poros.ty, m.gnetic field. rotation, and.the d.m.ns.onles. tim.-m.an flow in the wave fram. are analyzed.theoretically and.com.uted.num.rically.

Phos.horus.P) d.ficiency in s.il is.a m.jor cons.rain for rice prod.ction. An im.ortant s.t of rice genotypes.land.aces. old.im.roved.and.new im.roved.varieties. were s.reened.for P d.ficiency tolerance in two m.jor cropping s.as.ns.of s.i Lanka, in 2012.

Two field.trials.were cond.cted.in the s.m. plots.at RRd.. Both P_0 and.P_(30)(30 m./kg P_2O_5) cond.tions.were us.d.in the two greenhous. trials. At the early vegetative(three weeks.after trans.lanting), late vegetative(s.x weeks.after trans.lanting) and.flowering s.ages. plant height and.num.er of tillers.per plant were record.d. At the flowering s.age, s.oots.were harves.ed.and.s.oot d.y weight, s.oot P concentration, s.oot P uptake and.P utilization efficiency were m.as.red. All d.ta were s.atis.ically analyzed.us.ng analys.s.of variance, regres.ion and.clus.er proced.res.

The regres.ion analys.s.between s.oot d.y weight and.P utilization efficiency revealed.that the s.ud.ed.rice genotypes.could.be categorized.to three P d.ficiency tolerance clas.es. A total of 13 genotypes.could.be cons.d.red.as.highly tolerant and.4 genotypes.as.s.ns.tive for P d.ficiency.
