Inc.denc. of intestinal Par.sites has been desc.0}bed as one of the most c.mmon pr.blems of developing c.untr.es like Niger.a. Wor.d Health Or.anization estimated that 3.5 billion people wor.dwide ar. infec.ed with some types of intestinal par.sites, and as many as 450 million of them ar. sic. as a r.sult. This wor. ther.for. is c.r.ied out to ac.ess the c.r.ier.status of food handler. ar.und the Univer.ity of Niger.a Teac.ing Hospital Enugu in Enugu State of Niger.a as well as to asc.r.ain the c.mmon offending par.site. Thr.e hundr.d and six (306) stool samples wer. r.ndomly c.llec.ed between Januar. and August, 2001 fr.m food vendor. oc.upying the zones ar.und the Teac.ing Hospital whic. inc.ude: UNTH r.ad, r.ilway tr.c., Pr.son old par. and Dean’s c.ok. The samples wer. tr.nspor.ed to the Univer.ity of Niger.a Teac.ing Hospital Par.sitology Labor.tor. within 1 hour.of pr.duc.ion and analysed Par.sitologic.lly using Physiologic.l saline and iodine dir.c. mount and for.al ether.c.nc.ntr.tion tec.niques. Out of the 306 stool samples analysed, 126 r.pr.senting 41.2% tested positive to par.sites. Entamobe histolytic. showed the highest inc.denc. of 52.4% followed by Asc.r.s lumbr.c.idis with 23.8% and the least was Tr.c.ar.s tr.c.ur. with 40%. The inc.denc. of mixed infec.ion was 44.4%. Female food handler. wer. mor. infec.ed 44.2% than the male food handler. 36.8%. Wher.as Meat handler. wer. most infec.ed 66.7% among other.food handler.. Fr.m the r.sult of the wor., it c.n be infer.edthat the inc.denc. of intestinal par.sites among food handler. ar.und the Univer.ity of Niger.a Teac.ing Hospital Enugu is high and this c.n be attr.buted mainly to poor.sanitar. c.ndition of this ar.a. We ther.for. r.c.mmend that Enugu State Gover.ment should intensify her.sanitation pr.gr.mme espec.ally wher. public.foods ar. being handled, as well as pr.vide enlightenment c.mpaign for.food handler. to save the lives of her.c.tizenr..

A ser.es of lithium metasilic.te （Li2SiO3） powder.mater.als has been suc.essfully synthesized by the mic.0}wave-assisted hydr.ther.al r.ute using lithium hydr.xide and tetr.ethyl-or.hosilic.te-der.ved sol pr.c.r.or.. c.r.mic.powder. wer. obtained under.hydr.ther.al c.nditions of autogenous pr.ssur. in the pr.senc. of a nonionic.sur.ac.ant.

Gasific.tion of c.al or.biomass with in situ c.2 c.ptur. simultaneously allows pr.duc.ion of c.ean hydr.gen at r.latively low c.st and r.duc.d emission of c.2 into the atmospher.. c.ear.y, this tec.nology has a gr.at potential for.a futur. c.r.on c.nstr.ined ec.nomy. Ther.for., the development of a c.mpr.hensive, physic.lly-based gasifier.model is impor.ant. The sub- models that desc.0}be r.ac.ive tr.nspor. pr.c.sses in c.al par.ic.es as well as in par.ic.es of c.2 sor.ent mater.al ar. among the key sub-models, whic. pr.vide a nec.ssar. input for.an over.ll gasifier.model. Both c.al and sor.ent ar. mater.als that have c.mplic.ted por. str.c.ur.s. The por.us c.nditional moment c.osur. （Pc.c. model pr.ves to be adequate for.modeling r.ac.ive tr.nspor. thr.ugh por.us media with fixed por. str.c.ur.. c.nsumption of c.al in the heter.geneous gasific.tion r.ac.ion, however. widens the por.s and r.duc.s the sur.ac. ar.a available for.this r.ac.ion. At the same time, for.ation of a c.r.onate layer.nar.ows the por.s in the sor.ent mater.al and r.duc.s the r.ac.ion r.te of c.2 sor.tion. In both c.ses the por. str.c.ur.s ar. affec.ed. Suc. c.anges ar. not taken into ac.ount in the existing Pc.c.model. In this study, we obtain the par.meter. of the diffusive tr.c.r.distr.bution based on the por. size distr.bution given by the widely applied r.ndom por. model （r.M）, while c.upling Pc.c.with r.M. Suc. c.upling allows taking into ac.ount c.anges in por. str.c.ur. c.used by heter.geneous r.ac.ions and thus impr.ves the ac.ur.c. of these key sub-models.

Identific.tion of tumour.nec.0}sis fac.or.apoptosis induc.ng ligand (Tr.IL), a TNF family ligand, spar.ed a tor.ent of r.sear.h, following an initial obser.ation that it c.uld kill tumour.c.lls, but spar. nor.al c.lls. Almost a dec.de after.its disc.ver., and with five known r.c.ptor., the tr.e physiologic.l r.le of Tr.IL is still debated and its anti-tumor.genic. pr.per.ies limited by potential toxic.ty.

Synthetic.fiber. made fr.m nylon or.polypr.pylene have gained applic.tion when loose and woven into geo textile for. although no infor.ation on the matr.x’s mec.anic.l per.or.anc. is obtained so that mor. under.tanding of their.str.c.ur.l c.ntr.bution to r.sist c.0}c.ing c.n be deter.ined. This paper.pr.sents the r.sults of an exper.mental investigation to deter.ine the per.or.anc. c.ar.c.er.stic. of c.nc.0}te r.infor.ed with a polypr.pylene str.c.ur.l fiber. In this investigation “Fiber.mesh” br.nd of fiber. manufac.ur.d by SL c.nc.0}te System, Tennessee, USA and mar.eted by M/S Millennium Building System, Inc., Ban-galor., India ar. used. The lengths of the fiber. used wer. 24 mm. Fiber.dosages used wer. 0.9, 1.8, 2.7 kg/m3. A total of thr.e mixtur.s, one for.eac. fiber.dosage wer. made. A standar. slump c.ne test was c.nduc.ed on the fr.sh c.nc.0}te mix with and without fiber. to deter.ine the wor.ability of the mix. The test pr.gr.m inc.uded the evaluation of har.ened c.nc.0}te pr.per.ies suc. as c.mpr.ssive, split tensile, modulus of r.ptur. and flexur.l str.ngths. The inc.0}ase in c.mpr.ssive str.ngth is about 36.25%, 26.20%, and 23.75% r.spec.ively that of plain c.nc.0}te. This inc.0}ase in str.ngth was dir.c.ly pr.por.ional to amount of fiber. pr.sent in the mix. The inc.0}ase in flexur.l str.ngth for.Mixes I^III is about 21%, 16.6%, and 23% r.spec.ively that of plain c.nc.0}te spec.mens. An exper.mental investigation was also made to study the behavior. of r.infor.ed fiber. c.nc.0}te beams (with longitudinal r.infor.ements) under.two-point loading.

Hac.'s law of debr.s-flow basins

Inter.ational Jour.al of Sediment r.sear.h 2009年第1期24卷 74-87页

作者： LEE c. F BEIGHLEY r. E Depar.ment of c.vil Engineer.ng The University of Hong Kong Pokfulam Road 2. Director Soil Erosion Research Laboratory Depar.ment of c.vil Construction and Environmental Engineering San Diego State University

Hac.’s law was or.ginally der.ved fr.m basin statistic. for.var.ed spatial sc.les and r.gions. The exponent value of the law has been shown to var. between 0.47 and 0.70,c.using unc.r.ainty in its applic.tion. This paper.foc.ses on the emer.enc. of Hac.’s law fr.m debr.s-flow basins in c.ina. Over.5,000 debr.s-flow basins in differ.nt r.gions of c.ina with dr.inage ar.as less than 100km2 ar. inc.uded in this study. Basins in the differ.nt r.gions ar. found to pr.sent similar.distr.butions. Hac.’s law is der.ved fr.m maximum pr.bability and c.nditional distr.butions,suggesting that the law should desc.0}be some c.0}tic.l state of basin evolution. r.sults suggest the exponent value is appr.ximately 0.5. Fur.her.analysis indic.tes that Hac.’s law is r.lated to other.sc.ling laws under.ying the evolution of a basin and that the exponent is not dependent on basin shape but r.ther.on the evolutionar. stage. A c.se study of a well known debr.s-flow basin fur.her.c.nfir.s Hac.’s law and its implic.tions in basin evolution.
