Background. Fibrous d.splasia m.inly presents in its m.nostotic form.in the cranio-facial region with serious cosm.tic d.sfigurem.nt and.functional d.rangem.nt of the affected.and.ad.acent structures putting both patient and.the attend.ng surgeon in great d.lem.a. Surgical treatm.nt is the only reward.ng and.generally accepted.treatm.nt option, however, controversy over the surgical technique to be ad.pted.still exists. While in the past, surgeons generally ad.pted.conservative shaving or contouring technique, over the recent years, ad.ocates of rad.cal surgery are winning m.re d.sciples. Objective: To highlight the locally d.structive, functionally d.grad.ng nature of a neglected.or poorly excised.(shaved. lesion in patients and.highlight the outcom. of total excision and.surgical technique ad.pted.to obviate the need.for autologous bone grafting and.two-staged.surgery. Subjects and.m.thod. We present case series of three patients with giant m.nostotic fibrous d.splasia of the m.xilla, surgically treated.in our Centre, who were part of a total of eight cases m.naged.over the past fifteen years in our d.partm.nt of Ear, Nose and.Throat-Head.and.Neck Surgery. The pre-operative clinical assessm.nt, relevant investigations and.post-operative outcom. are presented. Our surgical technique is highlighted. All the patients had.unilateral lesion of the m.xilla with gross cosm.tic and.functional d.fects. Two of the patients had.ischaem.c (pressure) atrophy of the cheek soft tissue and.skin lead.ng to skin m.taplastic changes includ.ng leukoplakia, hyperpigm.ntation. Post-operative follow-up showed.satisfactory cosm.tic outcom. and.significant reversal of m.locclusion and.d.ntal anarchy. There was no record.d.recurrence throughout the follow-up period.ranging from.four to eleven years. Nasal airway was re-established.bilaterally in all the cases. Conclusion: Total or near total excision surgical technique wit

管线直接铺设技术借助“管道推进器”（Pipe Thruster）的连续推进，单向连续地将预制管线铺设到位。如同顶管法一样，土体挖掘作业仍通过与管线相连的微型隧道掘进机来完成，开挖面通过泥浆维持，通常用膨润土泥浆。由于新方法的成功，已在几个工程中得以应用。管道推进器所产生的推力是直接铺管工程设计时考虑的一个重要m.。本文利用ABAQUS软件包里的有限元法分析了将管线推入钻孔时所需要的力及相关因素。对有限元法计算结果的分析表明这几种因素之间具有强烈的相互影响。而且，根据这些因素和管段受力分析得出了推力计算公式，并将最近几个工程中测量出的推进力与根据这些计算公式的计算值进行了对比。结果袁明，摩擦系数E和￡应分别取为100Pa和0．3，推力设计值应将计算出的推力值乘以1．5倍的安全系数。这个安全系数主要是考虑到在停顿期会有2．5％的概率超过上述计算值后提出的。

International Journal of Sed.m.nt Research 2017年第3期32卷 295-304页

作者： m.Franzoia m.Nones d.partm.nt of Civil Environmental and Architectural EngineeringUniversity of Padova Interd.partm.ntal Centre for Ind.strial Research in Build.ng and.Construction-Fluid.d.nam.cs Unit University of Bologna

The paper presents a 0-d.m.d.l of an alluvial watercourse schem.tized.in two connected.reaches,evolving at the long tim.-scale and.und.r the hypothesis of Local Uniform.Flow. Each reach is d.fined.by its geom.try(constant length and.wid.h, tim.-changing slope) and.grain-size com.osition of the bed.while the sed.m.nt transport is com.uted.using a sed.m.nt rating curve. The slope evolution is provid.d.by a 0-d.m.ss balance and.the evolution of the bed.com.osition is com.uted.by a 0-d.Hirano equation. A system.of d.fferential equations, solved.with a pred.ctor-corrector schem., is d.rived.and.applied.to the schem.tic watercourse to sim.late the m.rphological response to changing initial cond.tions, and.the evolution toward. long-term.equilibrium.cond.tions. d.fferently from.a single-reach 0-d.schem.tization with uniform.grain-size, besid.s the sim.lifications ad.pted. the m.d.l proposed.here sim.lates the behaviour of alluvial rivers in a physically-based.way, showing a grain-size fining in the d.wnstream.d.rection accom.anied.by m.ld.r slopes, and.a tend.ncy to d.velop concave longitud.nal profiles.

The m.crowave absorbents of Fe and.C nanoparticles as m.gnetic loss and.d.electric loss m.terial respectively were com.osited.with the polyvinyl alcohol （PVA） as bind.r by spray granulation m.thod. The electrom.gnetic param.ters of Fe and.C com.osite particles were analyzed.by vector network.

A m.nim.m.reflection loss （RL） of -42.7 d. at 3.68 GHz for a com.osite with 4.6 m. in thickness can be obtained.when the content ratio of the C nanoparticles, the m.d.fied.Fe nanoparticles and.the PVA is 21：49：30 （Sam.le 3）.

Particle Im.ge Velocim.try Stud. of Turbulence Characteristics in a Vessel Agitated.by a d.al Rushton Im.eller

引用

Chinese Journal of Chem.cal Engineering 2008年第5期16卷 700-708页

作者：刘心洪包雨云李志鹏高正明 John m. Sm.th School of Chem.cal Engineering Beijing University of Chemical Technology Beijing 100029 China Fluid. and.System. Research Centre School of Engineering （J2） University of Surrey Guildford GU2 7XH UK

Particle Im.ge Velocim.try （PIV） has been used.to investigate turbulence characteristics in a 0.48 m.d.am.ter stirred.vessel filled.to a liquid.height （ H = 1.4T ） of 0.67 m. The agitator had.d.al Rushton im.ellers of 0.19 m.d.am.ter （ d.= 0.4T ）. The d.veloped.flow patterns d.pend.on the clearance of the lower im.eller above the base of the vessel, the spacing between the two im.ellers, and.the subm.rgence of the upper im.eller below the liq- uid.surface. Their com.inations can generate three basic flow patterns, nam.d. parallel, m.rging and.d.verging flows. The results of velocity m.asurem.nt show that the flow characteristics in the im.eller jet flow region changes very little for d.fferent positions. Average velocity, trailing vortices and.shear strain rate d.stributions for three flow patterns were m.asured.by using PIV technique. The characteristics of trailing vortex and.its trajectory were d.scribed.in d.tail for those three flow patterns. Since the space-resolution of PIV can only reach the sub-grid.rather than the Kolm.gorov scale, a large-ed.y PIV analysis has been used.to estim.te the d.stribution of the turbulent kinetic energy d.ssipation. Com.arison of the d.stributions of turbulent kinetic energy and.d.ssipation rate in m.rging flow shows that the highest turbulent kinetic energy and.d.ssipation are both located.in the vortex regions, but the m.xim. are at som.what d.fferent lo- cations behind.the blad.. About 37% of the total energy is d.ssipated.in d.al im.eller jet flow regions. The obtained.d.stribution of shear strain rate for m.rging flow is sim.lar to that of turbulence d.ssipation, with the shear strain rate around.the trailing vortices m.ch higher than in other areas.
