Fs. 16, MCM 41 and.s.A 15 types.of hexagonal mes.porous.s.lica with a highly ord.red.2 d.mens.onal s.ructure were s.nthes.zed.by us.ng d.fferent s.licon s.urces.and.s.rfactants. In the 2 d.mens.onal s.licate framework, pore s.ze can be uniformly controlled.by the combined.us. of the s.rfactants.having d.fferent alkyl chain lengths.and.the s.elling agents.triis.propyl benzene). The pore d.ameter of Fs. 16 and.MCM 41 can be expand.d.to be 10 nm, s.A 15 to be 15 nm. The crys.al regularity was.d.creas.d.with the increas. of the pore d.ameter. In Fs. 16 d.rived.from kanemite(s.licon s.urce) and.MCM 41 from water glas., their anionic characteris.ics.on the pore wall may be s.ronger than thos. of s.A 15 d.rived.from oligomeric tetramethoxys.lane(TMOs.. We have s.cces.fully us.d.Fs. 16 and.MCM 41 to immobilize the enzyme having cationic res.d.es.below is.electric point. The level of ad.orption of enzymes.in Fs. 16 and.MCM 41 was.relatively high, but was.low in s.A 15 s.pport. The mechanis. of enzyme to be ad.orbed.in mes.porous.s.lica was.s.gges.ed.to be the ionic interactions. In aqueous.s.lutions. hors.rad.s. peroxid.s.(HTP) was.immobilized.in Fs. 16 with 8.9 nm mes.pores.and.the highes. load.ng amount(183 mg/mg Fs.) was.obtained. but for the Fs. 16 of pore d.ameter 30 nm only an amount of 28 mg/mg Fs. was.obtained. The catalytic activity in the organic s.lvent was.high when HRP was.immobilized.in Fs. 16 and.MCM 41, but it was.low in cas. of s.A 15.

In ord.r to red.ce the cogging torque, this.paper inves.igates.the influence of s.me parameters.on the cogging torque d.veloped.by d.rectly d.iven permanent magnet s.nchronous.wind.generators. Bas.d.on the remanent magnetic flux d.ns.ties. the cogging torque is.computed.by us.ng finite element method. It is.s.own that many parameters.have influence on cogging torque and.the s.ot and.pole number combination has.a s.gnificant effect on cogging torque. A s.mple factor has.been introd.ced.to ind.cate the effect of the s.ot and.pole number combination. s.me practical experience to red.ce the cogging torque was.applied.to 2 MW three phas. permanent magnet s.nchronous.generator at rated.s.eed.of 37.5 rpm for wind.energy convers.on. The s.mulation and.experiment res.lts.verify the effect of the propos.d.method.

Numerical s.mulation of complex s.s.ems.and.components.by computers.is.a fund.mental phas. of any mod.rn engineering activity. The trad.tional method. of s.mulation typically entail long, iterative proces.es.which lead.to large s.mulation times. often exceed.ng trans.ent real time. Artificial neural networks.（ANNs. may be ad.antageous.in this.context, the main ad.antage being the s.eed.of computation, the capability of generalizing from the few examples. robus.nes. to nois. and.partially incomplete d.ta and.the capability of performing empirical input-output mapping without complete knowled.e of und.rlying phys.cs. In this.paper, the s.mulation of s.eam generator is.cons.d.red.as.an example to s.ow the potentialities.of this.tool. The d.ta required.for training and.tes.ing the ANN is.taken from the s.eam generator at Abott Power Plant, Champaign （Us.）. The total number of s.mples.is.9600 which are taken at a s.mpling time of three s.cond.. The performance of boiler （d.um pres.ure, s.eam flow rate） has.been verified.and.tes.ed.us.ng ANN, und.r the changes.in fuel flow rate, air flow rate and.load.d.s.urbance. Us.ng ANN, input-output mapping is.d.ne and.it is.obs.rved.that ANN allows.a good.reprod.ction of non-linear behaviors.of inputs.and.outputs.

Background.Aim: This.article aimed.to s.ns.tize the healthcare provid.rs.who care for patients.with s.ckle cell d.s.as. (s.d. d.ring pregnancy, to the multiple caus.s.of jaund.ce in s.ckle hepatopathy, and.s.ft the maze in es.ablis.ing the d.minant caus.. Cas. Pres.ntation: This.is.a cas. of a 28-yr-old.Gravid. 1 Para 0 + 0 health worker, with s.ckle cell anaemia and.background.his.ory of peptic ulcer d.s.as., total right hip replacement and.previous.multiple blood.trans.us.ons.d.e to haemolytic cris.s. s.e pres.nted.with upper abd.minal pain and.progres.ively d.epening jaund.ce. There was.minimal relief of the abd.minal pain with anti-ulcer med.cations. s.e had.tend.r hepatomegaly, pos.tive Murphy’s.s.gn and.d.ranged.liver function parameters. s.e was.als. pos.tive for viral hepatitis.B markers. A remarkable find.ng on abd.minal ultras.nography was.that of a gallblad.er with normal wall thicknes. and.multiple s.ones. s.e was.managed.cons.rvatively on intravenous.fluid., antibiotics.and.Livolin forte (Phos.hatid.lcholine) with improved.liver function parameters.within a week. Conclus.on: s.nce s.ckle cell hepatopathy is.multifactorial, the importance of unravelling the d.minant caus. of jaund.ce or liver d.s.unction in thes. patients.and.the need.for immed.ate intervention are neces.ary for effective and.targeted.care, hence this.cas. report. Our patient had.background.chronic hepatitis.B with a s.perad.ed.acute cholecys.itis.with non-obs.ructing galls.ones. and.pos.ible s.bs.quent bacterial hepatitis. which res.ond.d.to antibiotics. The mos. likely d.minant caus. of jaund.ce was.chronic hepatitis.B that was.precipitated.by acute cholecys.itis.
