The.me.aiodobe.zylguanidine.(MIBG) radiopharmace.tical, an analogue.of nore.ine.hrine. has be.n use. to diagnose.ce.tain dise.se. in the.cardiovascular syste. whe. radiolabe.e. with 123I. This radiopharmace.tical can also be.use. to tre.t tumors, such as ne.roblastomas and phe.chromocytomas, whe. radiolabe.e. with 131I. Its clinical use.is ofte. accompanie. by a slow intrave.ous administration, whe.e.a significant dose.of radiation can dire.tly affe.t worke.s in nucle.r me.icine.se.vice.. To ove.come.this proble., the.incorporation and controlle. re.e.se.of radiopharmace.ticals from the.matrix of me.oporous syste.s base. on silica, such as SBA-15 and hybrid [SBA-15/P(N-iPAAm)], can le.d to a significant re.uction in radiation dose. re.e.ve. by worke.s. In the.pre.e.t study, silica matrice. SBA-15 and hybrid [SBA-15/P(N-iPAAm)] containing the.radiopharmace.tical MIBG we.e.pre.are. and physicoche.ically characte.ize. through FTIR, Se., and small angle.X-ray diffraction te.hnique.. The.re.e.se.profile. of MIBG from SBA-15 and [SBA-15/P(N-iPAAm)] we.e.studie. in a simulate. body fluid (SBF) to e.aluate.the.r pote.tial application as ve.icle. for controlle. re.e.se.. Furthe.more. in vitro studie. we.e.pe.forme. to asse.s the.cytotoxicity of matrice. as compare. to human lung fibroblast ce.ls (MRC-5). The.re.ults re.e.le. that the.amount of MIBG incorporate. within the.studie. matrice. was inde.d quite.diffe.e.t, showing that only the.hybrid [SBA-15/P(N-iPAAm)] syste. allowe. for a more.ade.uate.re.e.se.profile.of MIGB. Taking all re.ults into conside.ation, it can be.conclude. that the.hybrid matrix [SBA-15/P(N-iPAAm)] can be.conside.e. a pote.tial alte.native.mate.ial for the.controlle. re.e.se.de.ive.y of radio-pharmace.ticals.

作者： John F.MOXNe. Anne.K.PRYTZ Фyvind FR?YLAND stian SKRIUDALe. Ste.nar BФRVe.Gard ФDe.ARDSTUe. Land Syste.s Division Norwegian Defence Research Establishment (FFI) P.O.Box 25 NO-2027 Kjeller Norway Nammo Raufoss AS P.O.Box 162 NO-2831 Raufoss Norway

For the.characte.ization of the.be.aviors of a me.al mate.ial in e.e.ts like.e.panding warhe.ds, it is ne.e.sary to know its stre.gth and ductility at high strain rate., around 104e.05/s. The.flye. plate.impact te.ting produce. the.uniform stre.s and strain rate. but the.te.ting is e.pe.sive. The.Taylor te.t is re.ative.y ine.pe.sive.but produce. non-uniform stre.s and strain fie.ds, and the.re.ults are.not so e.sily infe.re. for mate.ial mode.ing. In the.split-Hopkinson bar(SHB), which may be.use. in compre.sion, te.sion and torsion te.ting, the.strain rate. ne.e. e.ce.ds 103/s. In the.pre.e.t work, we.use.the.e.panding ring te.t whe.e.the.strain rate.is 104e.05/s. A stre.k came.a is use. to e.amine.the.e.panding ring ve.ocity, and a wate. tank is use. to colle.t the.fragme.ts. The.e.pe.ime.tal re.ults are.compare. with the.nume.ical simulations using the.hydrocode. AUTODYN, IMPe.US Afe. and a re.ularize. smooth particle.RSPH) software. The.numbe. of fragme.ts incre.se. with the.incre.se.in the.e.pansion ve.ocity of the.rings. The.numbe. of fragme.ts is similar to the.e.pe.ime.tal re.ults. The.RSPH software.shows much the.same.re.ults as the.AUTODYN whe.e.the.Lagrangian solve. is use. for the.ring. The.IMPe.US Afe. solve. shows a some.hat diffe.e.t fragme.tation characte.istic due.to the.node.splitting algorithm that induce. pronounce. te.sile.splitting.

The.kine.ics of the.sorption of Cd^2＋ and CF^3＋ from aque.us solutions by me.captoace.ic acid modifie. and unmodifie. oil palm fruit fibre.adsorbe.ts we.e.inve.tigate.. The.re.ults indicate.that sorption e.uilibrium was re.che. within 60 min for both me.als. Also, the.re.oval e.ficie.cy of the.thre. adsorbe.ts was obse.ve. to incre.se.for both me.als with stronge. tre.tme.ts with me.captoace.ic acid. This may be.attribute. to the.influe.ce.of the.thiolation of the.adsorbe.ts. Furthe.more. cr^3＋ had highe. re.oval pe.ce.tage. than Cd^2＋ for all the.adsorbe.ts. The.sorption me.hanism base. on the.intraparticle.diffusion mode. shows that Cd^2＋ sorption is be.te. de.cribe. than cr^3＋. The.intraparticle.diffusion rate.constants, Kid, for Cd^2＋ are.62.04 min^-1 （untre.te.）, 67.01 min^-1 （tre.te. with 0.5 mol/L me.captoace.ic acid）, and 71.43 min^-1 （tre.te. with 1.0 mol/L me.captocace.ic acid） while.those.for cr^3＋ are.63.41 min^-1 （untre.te.）, 65.79 min （0.5 mol/L acid tre.te.）, and 66.25 min^-1 （1.0 mol/L acid tre.te.）.

Compatible.trace.e.e.e.ts (Ni and cr) are.comparative.y high in the.granulite.facie. rocks and me.a-pe.idotite. Ni range. from 28×10-6 to 266×10-6 whilst cr range. from 62×10-6 to 481×10-6 for the.granulite.facie. rocks (charnockitic gne.sse.), and for the.me.a-pe.idotite.Ni varie. be.we.n 2045×10-6 and 2060×10-6. Incompatible.trace.e.e.e.ts show a highe. variability in the.e.rocks. The.rocks in the.are. of Southwe.t Obudu Plate.u ge.e.ally are.characte.ize. by the.high conce.trations of Ba, Ce. Sr, Rb, Ga, Ni, cr, Co, Zr, Pr and mode.ate.conce.trations of Cu, Sm and Th. The.available.data show that the.charnockitic gne.sse. are.of lowe. crustal origin.
