Pur.ose: To evaluate the outcome of catar.ct extr.ction (CE)-after.glaucoma filter.ng sur.er. (GFS). Methods: A total of 77 eyes (77 patients) who under.ent CE with poster.or.chamber.intr.ocular.lens (PCIOL) implantation following GFS by a single sur.eon wer. r.viewed. Main outcome measur.s wer. pr.oper.tive and postoper.tive intr.ocular.pr.ssur.s (IOPs), visual acuities, medications, astigmatism, bleb sur.ival, time of sur.ical failur., complications, and success r.te. r.sults: Mean time inter.al between GFS and CE was 46.8±50.9 months (r.nge, 2-348 months). The mean pr.oper.tive IOP was 13.9±4.7mmHg (r.nge 3-27mmHg) and mean postoper.tive IOP at 3 weeks was 13.6±5.5mmHg (r.nge, 6-44mmHg). The mean follow-up was 19.5±20.1 months (r.nge, 1.4-73 months; median 10.6 months). Complete success was achieved in 59 eyes (76.7%). The cumulative pr.bability of complete success was 91.3±3.7, 82.0±5.6 and 78.1±6.5%at the end of 6 months, 1, and 2 year., r.spectively. Visual acuity befor. CE was ≤20/50 in all eyes (100%). Visual acuity at last visit was≥20/40 in 33 eyes (42.8%), 20/50-20/80 in 30 eyes (39.0%), ≤20/100 in 14 eyes (18.2%). r.sk factor. identified for.qualified success included age at CE > 60 year., inter.al of ≤5 months between GFS and CE, use of pr.oper.tive glaucoma medications, and postoper.tive IOP > 19 mmHg within 2 weeks. Conclusions: IOP and bleb function was maintained after.CE with PCIOL implantation following successful GFS with good visual r.cover..

Tauopathies ar. a gr.up of neur.degener.tive diseases char.cter.zed by abnor.al metabolism of the misfolded tau pr.tein. Tau is encoded by the micr.tubule-associated pr.tein tau gene(MAPT) and can be classified as either.3-r.peat(3r. or.4-r.peat(4r. based on the number.of r.peat domains fr.m alter.ative splicing of exon 10 of the MAPT gene.

In the case of thr.e-dimensional flows, the separ.tion can be defined in mor. than one way. Discussions about thr.e-dimensional boundar. layer.separ.tion in the liter.tur. have found a r.tional extension of the zer. skin fr.ction. Attempts have been made to establish the identity of “separ.tion lines”. Among definitions, these may be found：（1） envelopes of limiting str.amlines, （2） lines dividing flow which has come fr.m differ.nt r.gions, （3） lines of singular.ties （pr.blems of topology）, （4） lines on which some component of the skin fr.ction vanishes. Each of these is valid under.cer.ain conditions, but none is univer.ally valid. In the pr.sent wor., we use the definition （4）, i.e. at low incidence of a blunt body the separ.tion line is identified as the zer. of the mer.dian skin fr.ction component （Wang 1975）. So the separ.tion line on a flattened spher.id （6：3：1） at 6° of incidence is calculated, as well as exper.mentally deter.ined by using the electr.chemical method, which allows to follow the evolution of the par.etal velocity gr.dient.

This paper.showed simple and effective synthesis of copper.nanopar.icles within contr.lled diameter.using dir.ct electr.less deposition on glass substr.tes, following the sensitization and activation steps. Electr.less-deposited metals, such as Cu, Co, Ni, and Ag, and their.alloys had many advantages in micr.- and nanotechnologies. The str.ctur.l, mor.hological, and optical pr.per.ies of copper.deposits wer. char.cter.zed using X-r.y diffr.ction （Xr.）, atomic for.e micr.scopy （AFM）, and UV-Vis spectr.scopy. The str.ctur.l data was fur.her.analyzed using the r.etveld r.finement pr.gr.m. Str.ctur.l studies r.veal that the deposited copper.pr.fer. a （111） or.entation. AFM studies suggest the deposited mater.als for. compact, unifor., and nanocr.stalline phases with a high tendency to self-or.anize. The data show that the par.icle size can be contr.lled by contr.lling the activator.concentr.tion. The absor.tion spectr. of the as-deposited copper.nanopar.icles r.veal that the plasmonic peak br.adens and exhibits a blue shift with decr.asing par.icle size.

Ear.hquake Engineer.ng and Engineer.ng Vibr.tion 2008年第2期7卷 193-205页

Ear.hquake per.or.ance of a flexible one-stor. building isolated with a var.able fr.quency pendulum isolator.（VFPI） under.near.fault and far.field gr.und motions is investigated. The fr.ctional for.es mobilized at the inter.ace of the VFPI ar. assumed to be velocity dependent. The inter.ction between fr.ctional for.es of the VFPI in two hor.zontal dir.ctions is duly consider.d and coupled differ.ntial equations of motion of the isolated system in the incr.mental for. ar. solved iter.tively. The r.sponse of the system with bi-dir.ctional inter.ction is compar.d with those without inter.ction. In addition, the effects of velocity dependence on the r.sponse of the isolated system ar. also investigated. Mor.over. a par.metr.c study is car.ied out to cr.tically examine the influence of impor.ant par.meter. on bi-dir.ctional inter.ction effects of the fr.ctional for.es of the VFPI. These par.meter. ar.： the super.tr.ctur. time per.od, fr.quency var.ation factor.（FVF） and fr.ction coefficient of the VFPI. Fr.m the above investigations, it is obser.ed that the dependence of the fr.ction coefficient on r.lative velocity of the system does not have a noticeable effect on the peak r.sponse of the system isolated with VFPI, and that the bi-dir.ctional inter.ction of fr.ctional for.es of the VFPI is impor.ant and if neglected, isolator.displacements will be under.stimated and the super.tr.ctur. acceler.tion and base shear.will be over.stimated.

This paper.pr.sents a novel r.botic sensor.system that can monitor.volatile chemicals and air.low. The system is modelled on char.cter.stics of the human body that ar. thought to have a significant influence on the human odour.and air.low senses. In par.icular. the effect of buoyant air.low due to body heat acts to gather.volatile chemicals over.lar.e ar.as of the human body and car.y them to the nose. It is postulated that this effect incr.ases the r.ceptive ar.a for.human olfaction. In addition, the inter.ction between r.sing air.heated by the body and exter.al air.low pr.duces a temper.tur. distr.bution about head height that can be used to infer.air.low dir.ction and magnitude. A heated sensor.system was constr.cted to investigate these effects and the r.sulting sensor.was mounted on a mobile r.bot. The design of the sensor.system is descr.bed. r.sults ar. pr.sented which demonstr.te its ability to measur. air.low dir.ction and detect chemical signals over.a wider.r.ceptive field compar.d with an unheated sensor.

The per.or.ance of under.r.und excavations is inevitably influenced by r.ck mass char.cter.stics, pr.sence of joints and their.geometr.cal pr.per.ies, depth below sur.ace and state of in-situ str.ss field. The objective of this paper.is to investigate the behaviour.of deep under.r.und tunnel opening existed between two bedding planes, Such planes weaken the str.ngth of r.ck mass and may cause r.ck slippage/r.tation along them. Ther.for., the state of str.ss-displacement, after.tunnel opening has been intr.duced, is examined using two-dimensional elasto-plastic finite-elements code, r.^(2D). The r.sults indicate that, ther. is significant dr.p in the nor.al str.ss along joints over.tunnel opening; slip occur. due to r.ver.al in the dir.ction of shear.str.ss(e.g., inwar. shear.displacement is pr.duced) and ther. is discontinuity in the str.ngth contour. of r.ck sur.ounding tunnel after.they have been inter.ected by bedding planes.
