He was.164 cm tall and weighed 55 kg. This.man donated his.body to s.ience. Her body was.frozen and cut into s.veral anatomical s.ctions.after an MRI and CT s.an. Thes. anatomical s.ctions.were made us.ng a s.ecial s.w called a 0.2 mm thick cryomacrotome. Thus.8100 cuts.were obtained. Only the s.ctions.numbered 940 to 1200 were us.d for our s.udy. A s.gmentation by manual contouring of the different parts.of the typical cervical vertebra was.made us.ng the s.ftware Wins.rf vers.on 3.5 on a laptop PC running Windows.7 equipped with a Ram of 8 gigas. s.rong>Res.lts.s.rong> Our 3D vector model of the typical cervical vertebra is.eas.ly manipulated us.ng the Acrobat 3DPDF interface. Each part of the vertebra acces.ible in a menu can be dis.layed, hidden or made trans.arent, and 3D labels.are available as.well as.educational menus.for learning anatomy. s.rong>Conclus.on: s.rong>This.original work cons.itutes.a remarkable educational tool for the anatomical s.udy of the typical cervical vertebra and can als. be us.d as.a 3D atlas.for s.mulation purpos.s.for training in therapeutic ges.ures.

Electro-os.otic flow of a s.cond-grade fluid in a porous.microchannel s.bj.ct to an AC electric field

引用

j.urnal of Hydrodynamics 2013年第2期25卷 309-316页

作者： MIs.A j. C. CHANDRA s. Department of Mathematics Institute of Technical Education and Research Siksha O Anusandhan University Department of Phys.cs Sabang S. K. Mahavidyalaya Vidyasagar University

s.udies.on electro-os.otic flows.of various.types.of fluids.in microchannel are of great importance owing to their multifold applications.in the trans.ort of liquids. particularly when the ionized liquid flows.with res.ect to a charged s.rface in the pres.nce of an external electric field. In the cas. of vis.oelas.ic fluids. the volumetric flow rate differs.s.gnificantly from that of Newtonian fluids. even when the flow takes.place under the s.me pres.ure gradient and the s.me electric field. With this.end in view, this.paper is.devoted to a s.udy concerning the flow pattern of an electro-os.otic flow in a porous.microchannel, which is.under the action of an alternating electric field. The influence of various.rheological and electro-os.otic parameters. e.g., the Reynolds.number, Debye-Huckel parameter, s.ape factor and fluid vis.oelas.icity on the kinematics.of the fluid, has.been inves.igated for a s.condgrade vis.oelas.ic fluid. The problem is.firs. treated by us.ng analytical methods. but the quantitative es.imates.are obtained numerically with the help of the s.ftware MATHEMATICA. The res.lts.pres.nted here are applicable to the cas.s.where the channel height is.much greater than the thicknes. of the electrical double layer compris.ng the s.ern and diffus. layers. The s.udy reveals.that a larger value of the Debye-Huckel parameter creates.s.arper profile near the wall and als. that the velocity of electro-os.otic flow increas.s.as.the permeability of the porous.microchannel is.enhanced. The s.udy further s.ows.that the electro-os.otic flow dominates.at lower values.of Reynolds.number. The res.lts.pres.nted here will be quite us.ful to validate the obs.rvations.of experimental inves.igations.on the characteris.ics.of electro-os.otic flows.and als. the res.lts.of complex numerical models.that are neces.ary to deal with more realis.ic s.tuations. where electro-os.otic flows.come into the picture, as.in blood flow in the micro-circulatory s.s.em s.bj.ct to an elect
