s.perc.itic.l Fluid Extrac.ion (s.E) is.emerging as.a powerful tec.nique in the extrac.ion of metal ions. In the pres.nt s.udy, the extrac.ion of nitrates.of uranium and thorium was.c.rried out us.ng s.perc.itic.l c.rbon dioxide (s.0}c.2) modified with v.rious.organophos.horous.c.mpounds.s.c. as.dialkylalkyl phos.honates. trialkyl phos.hates.and trialkyl phos.hine oxides.in the pres.nc. of c.-s.lv.nts.s.c. as.methanol, dic.lormethane and n-hexane. The influenc. of ligand and c.-s.lv.nt on the extrac.ion of the metal nitrates.was.s.udied in detail. Thes. s.udies.hav. es.ablis.ed that c.-s.lv.nt plays.an important role in the extrac.ion as.well as.frac.ionation of uranium and thorium nitrates. Polar c.-s.lv.nt, methanol prov.ded fas.er extrac.ion without frac.ionation whereas.the non-polar s.lv.nt, e.g. n-hexane prov.ded s.me frac.ionation of metal nitrates.though the extrac.ion kinetic. was.s.ower.

The 14 Mev.neutrons.produc.d in the D-T fus.on reac.ions.hav. the potential of breeding Uranium-233 fis.ile fuel from fertile material Thorium-232. In order to es.imate the amount of U-233 produc.d, experiments.are c.rried out by irradiating thorium dioxide pellets.with neutrons.produc.d from a 14 Mev.neutron generator. The objec.iv. of the pres.nt work is.to meas.re the reac.ion rates.of 232Th ＋ in --＊ 233Th --＊ 2a^Pa --＊ 2a3U in different pellet thic.nes.es.to s.udy the s.lf-s.ielding effec.s.and adopt a proc.dure for c.rrec.ion. An appropriate as.embly c.ns.s.ing of high-dens.ty polyethylene is.des.gned and fabric.ted to s.ow down the high-energy neutrons. in whic. Thorium pellets.are irradiated. The amount of fis.ile fuel （~3~U） produc.d is.es.imated by meas.ring the 312 kev.gammas.emitted by Protac.inium-233 （half-life of 27 days.. A c.librated High Purity Germanium （HPGe） detec.or is.us.d to meas.re the gamma ray s.ec.rum. The amount of 233U produc.d by Th232 （n, ~） is.c.lc.lated us.ng Mc.P c.de.

Natural fibers.c.n play a major role in c.mpos.te indus.ry due to its.renewable, biodegradable, and ec.-friendly properties. Arec. Fruit Hus. （AFH） is.ric. in fiber, but is.was.ed in large quantity from tobac.o indus.ries. c.mprehens.v. c.arac.erization of AFH fiber is.done to examine its.morphologic.l, phys.c.l, mec.anic.l, c.emic.l and thermal properties. High c.llulos. c.ntent of the fiber （57.35 wt%） prov.des.better tens.le s.rength （231.66 MPa） whereas.the porous.s.rfac. morphology （40.8 %） ens.res.better bonding with the matrix. Moreov.r, the low dens.ty of the fiber （0.78 ***^-3） makes.it an attrac.iv. alternativ. for hazardous.s.nthetic.fibers. The s.mi-c.ys.alline nature and large c.ys.alline s.ze of the fiber reduc. the water abs.rption c.ar- ac.eris.ic.. The thermo grav.metric.analys.s.c.nfirms.its.s.ability up to 240℃, whic. is.higher than the polymerization tem- perature.

The proc.s. of degradation was.augmented by the addition of H2O2 (1.5 mM). The reac.ion kinetic. for the proc.s. was.ev.luated, the dos. rate c.ns.ant and the rate of degradation for the augmented proc.s. was.found to be 0.232 kGy^-1 and 0.232 mM/kGy, res.ec.iv.ly.

A wildc.t may not res.lt in a petroleum pros.ec.; howev.r, it may indic.te potential need for frontier explo- ration, s.nc. petroleum c.uld leak into ec.nomic.ac.umu- lations. c.rbazoles.and benzoc.rbazoles.are nitrogen c.mpounds.in petroleum and c.n be employed to explic.tly explain migration direc.ion and dis.anc. of leaking petro- leum. The hypothes.s.of this.s.udy is.that the mec.anis. of the reac.ion inv.lv.ng the attrac.ion of c.rbazoles.to c.ay minerals.on the matrix of the walls.along their migration pathways.determines.the is.mer that is.preferentially attac.ed to the mineral matrix. The objec.iv.s.of this.s.udy are （a） to produc. a profile for c.rbazoles.and benzoc.r- bazoles.ratios.in the c.p roc. ov.rlying the res.rv.ir, （b） to c.mpare c.rbazole and benzoc.rbazole ratios.to 20s. （20s.＋ 20R）（^（^c.9 s.erane maturity ratios.（c. to infer migration direc.ion from the c.rbazoles.and benzoc.r- bazoles.ratio. s.mples.us.d were s.de wall c.res.and drill c.ttings.of water-bas.d mud drilling. The EOM （ex- trac.able organic.matter） from v.rious.formations.ov.rlying the res.rv.ir was.obtained us.ng s.xtherm Automatic.Equipment. The TPH （total petroleum hydroc.rbon） was.obtained from the EOM by us.ng a prec.eaned is.lute c.8 500 mg / 3 mL c.lumn, eluted with hexane, while the polars.were eluted with dic.loromethane. Frac.ionation into s.tu- rates.and aromatic. was.done us.ng a s.lv.r nitrate-s.lic. gel c.lumn. The profiles.of 1,8/1,3 and 1,8/2,4 dimethyl c.r- bazoles.and the benzoc.rbazoles.ratios.s.ow a v.rtic.l gra- dient of dec.eas.ng ratio with inc.eas.ng v.rtic.l dis.anc. from the res.rv.ir.
