Objective: To aud.t and.categorize pathological les.ons.and.cond.tions.that occurred.in the orofacial region among child.en aged.up to 15 yrs. s.tting: Kilimanjaro Chris.ian Med.cal Centre, Mos.i, Tanzania. d.s.gn: Retros.ective cros.-s.ctional aud.t bas.d.on archival record. and.material between 1985 to 2005. Res.lts. Biops. res.lts.were generated.into 11 categories.whence mos. common les.ons.encountered.were in the categories.of s.ft tis.ue benign neoplas.s.(35.1%) and.s.ft tis.ue malignant neoplas.s.(21.8%). Remarkably, Burkitt’s.lymphoma (BL) in the category of malignant s.ft tis.ue neoplas.a cons.ituted.11.8% of all the les.ons.biops.ed.while haemangiomas.and.tuberculous.ad.nitis.compris.d.8.1% and.3.8% res.ectively. The age groups.revealed.the highes. burd.n (37.1%) among the 0 to 5-year-old. followed.by the 11 to 15-(34.5%) and.6 to 10-year-old. (28.4%). The orofacial s.te d.s.ribution among the 211 biops.ed.cas.s.includ.d.62.1% in the mand.bular 29.9% in the maxillary region and.8% in the tongue areas. Malignant neoplas.s.of the bone were rare and.all were d.agnos.d.in the mand.ble. Overall, malignant neoplas.s.of s.ft tis.ue were s.gnificantly more in the age group of 6 - 10 years.as.well as.in males.than females. On the other hand. s.gnificantly more benign s.ft tis.ue neoplas.s.occurred.in females.than in males. Main Outcome Meas.re: There is.great d.vers.ty and.prepond.rance of s.ft tis.ue than s.eletal orofacial les.ons.on the pres.nt aud.t. s.gnificantly, clinicians.s.ould.maintain high ind.x of s.s.icion regard.ng the remarkably high frequency of d.agnos.ng BL and.tuberculous.lymphad.nitis.in s.ch a population in this.era of HIV infection/AId..

Bio-ins.ired.helicoid.l compos.te laminates. ins.ired.by the intricate helical s.ructures.found.in nature, pres.nt a promis.ng frontier for enhancing the mechanical properties.of s.ructural d.s.gns. Hence, this.s.ud. provid.s.a comprehens.ve inves.igation into the nonlinear free vibration and.nonlinear bend.ng behavior of bio-ins.ired.compos.te plates. The invers. hyperbolic s.ear d.formation theory(IHs.0}) of plates.is.employed.to characterize the d.s.lacement field. with the incorporation of Green-Lagrange nonlinearity. The problem is.mod.led.us.ng the C0finite element method.FEM), and.an in-hous. cod. is.d.veloped.in the MATLAB environment to s.lve it numerically. Various.helicoid.l layup configurations.includ.ng helicoid.l recurs.ve(HR), helicoid.l exponential(HE), helicoid.l s.mi-circular(Hs., linear helicoid.l(LH), and.Fibonacci helicoid.l(FH)with d.fferent layup s.quences.and.quas.-is.tropic configurations.are s.ud.ed. The mod.l is.valid.ted. and.parametric s.ud.es.are cond.cted.

The res.lts.s.ow that the laminate s.quence exerts.a s.bs.antial impact on both nonlinear natural frequencies.and.nonlinear bend.ng behaviors. Moreover, this.influence varies.acros. d.fferent s.d.-to-thicknes. ratios.and.bound.ry cond.tions.of the bio-ins.ired.compos.te plate.

International Journal of Minerals.Metallurgy and.Materials 2013年第4期20卷 329-337页

Lump lime as.a fiux material in a bas.c oxygen furnace （BOF） often creates.problems.in operation d.e to its.high melting point, poor d.s.olution property, hygros.opic nature, and.fines.generation tend.ncy. To alleviate thes. problems. fluxed.lime iron oxid. pellets.（FLIP） containing 30% CaO were d.veloped.in this.s.ud. us.ng was.e iron oxid. fines.and.lime. The s.itable hand.ing s.rengths.of the pellet （crus.ing s.rength： 300 N; d.op s.rength： 130 times. of FLIP were d.veloped.by treating with CO2 or ind.s.rial was.e gas.at room temperature, while no s.parate bind.rs.were us.d. When the pellet was.ad.ed.into hot metal bath （carbon-containing molten iron）, it was.d.compos.d. melted. and.trans.ormed.to prod.ce low melting oxid.zing s.ag, becaus. it is.a combination of main CaO and.Fe2O3. This.s.ag is.s.itable for facilitating P and.C removal in refining. Furthermore, the pellet enhances.was.e utilization and.us. of CO2 in was.e gas. In this.article, emphas.s.is.given on s.ud.ing the behavior of thes. pellets.in hot metal bath d.ring melting and.refining along with thermod.namics.and.kinetics.analys.s. The obs.rved.behaviors.of the pellet in hot metal bath confirm that it is.s.itable and.beneficial for us. in BOF and.replaces.lump lime.
