Bac.ground/aim: Sub-Tenon’s bloc. (STB) or topic.l anaesthesia alone (TOP) are popular tec.niques employed during c.tarac. surgery. TOP is often preferred b y healthc.re providers bec.use of financ.al or staffing reasons, despite existing evidenc. that pain during surgery is better c.ntrolled with STB. Pain is not the only c.nsideration that determines patient preferenc. for the anaesthesia tec.hnique. The authors dec.ded to investigate the issue of patient satisfac.ion usi ng the rec.ntly developed Iowa Satisfac.ion with Anesthesia Sc.le (ISAS). Method : In a randomised c.ntrolled pilot trial, 28 patients were enrolled to rec.ive e ither STB with 3 ml of 2%lidoc.ine and hyaluronidase, or TOP with proxymetac.in e 0.5%and amethoc.ine 1%(Tetrac.ine) eye drops. Postoperatively patients rated their satisfac.ion with anaesthesia c.re by filling in the self administered wr itten questionnaire, the ISAS. Results: One patient in the TOP group dropped out of the study bec.use of intolerable pain. Analysis of the questionnaire results with a two sample Wilc.xon rank sum test showed a signific.nt differenc. in pat ient satisfac.ion (pc.ion sc.re was higher in the S TB group 2.77 (interquartile range IQR 2.45 to 3), than in the TOP group 2.04 (I QR 1.54 to 2.5). c.nc.usion: In the setting of day c.se c.tarac. surgery, patien ts report signific.ntly higher satisfac.ion sc.res with STB than with TOP alone.

During the interval 06:14―07:30 UT on August 24, 2005, sinc. the Earth’s magneto- pause was suddenly c.mpressed by the persistent high-speed solar wind stream with the southward c.mponent of the interplanetary magnetic.field (IMF), the magnetopause moved inward for about 3.1 RE. Meanwhile, Tc.1 satellite shifted from northern plasma sheet to the northern lobe/mantle region, although it kept inward flying during the interval 06:00―07:30UT. The shift of Tc.1 from the plasma sheet to the lobe/mantle is c.used by the simultaneous inward displac.ments of the plasma sheet and near-Earth lobe/mantle region, and their inward movement veloc.ty is larger than the inward motion veloc.ty of Tc.1. The joint inward dis-plac.ments of the magnetopause, the lobe/mantle region and the plasma sheet indic.te that the whole magnetosphere shrinks inward due to the magnetospheric.c.mpression by the high-speed solar wind stream, and the magnetospheric.ions are attac.ed to the magnetic.field lines (i.e. ‘frozen’ in magnetic.field) and move inward in the shrinking proc.ss of magnetosphere. The large shrinkage of magne-tosphere indic.tes that the near-Earth magnetotail c.mpression c.used by the strong solar wind dynamic.pressure is muc. larger than its thic.ening c.used by the southward c.mponent of the IMF, and the loc.tions of magnetospheric.regions with different plasmas vary remarkably with the variation of the solar wind dynamic.pressure.

With the 4-s resolution data of the magnetometer and the ion plasma analyzer on Tc.1 from June to November of eac. year during the period of 2004―2006, we statistic.lly analyzed the oc.urrenc. rate of both c.nvec.ive and field-aligned bursty flows (FABFs). A near-Earth bursty bulk flow (NEBBF) oc.urred during both the quiet time and substorm proc.ss. In general, the magnetic.field and the plasma density began osc.llating with the appearanc. of the NEBBF assoc.ated with a distinc. inc.ease of the AE index. The inc.ease of AE index during the NEBBF was more than 100 nT in both quiet time and substorm proc.ss. The statistic.l analysis indic.ted that the oc.urrenc. rates of the FABFs were nearly the same in the dif-ferent stages of the AE index, but the oc.urrenc. rate of the NEBBFs was muc. higher in the growth stage of the AE index, indic.ting that the NEBBFs were di-rec.ly related to the growth and expansion phases of the substorm. The observa-tions suggested that the quite large number of BBFs from the mid magnetotail c.uld enter into the near-Earth tail and play important role in triggering the sub-storm onset.

An event of c.uster-Double Star c.njunc.ion observations of magnetic.rec.nnec.tion at high latitude magnetopause nightside of both c.sps and solar wind trans-port into magnetosphere c.used by suc. rec.nnec.ion proc.ss has been investi-gated. During northward IMF, c.uster/Sc. observed ac.elerated flows and ion heating assoc.ated with magnetic.rec.nnec.ion at high latitude magnetopause nightside of southern c.sp. And Double Star observed c.ld dense solar wind plasma transported into dayside magnetosphere. The analysis on suc. c.njunc.ion observations shows that: (1) during northward IMF, magnetic.rec.nnec.ion oc.urs at high latitude nightside of southern c.sp, ac.ompanied by ac.elerated flows that are observed by c.uster/Sc.; (2) the direc.ion of the ac.elerated flows, with its sunward c.mponent Vx, dawnward c.mponent Vy, northward c.mponent Vz, is quite c.nsistent with the theoretic.l antic.pation under the c.ndition of northward IMF with dawnward c.mponent By; (3) rec.nnec.ion c.n heat plasma more in par-allel direc.ion than in perpendic.lar direc.ion, to a level of about 4 keV; (4) with rec.nnec.ion taking plac. at high latitude magnetopause nightside of the southern c.sp, Tc.1 observed c.ld and dense plasma transported into magnetosphere; (5) by rec.nnec.ion at high latitude magnetopause nightside of both c.sps, solar wind flux tube c.n be c.ptured by magnetosphere and pulled into dayside magneto-sphere. This event presents further observational evidenc. for magnetic.rec.nnec.tion at high latitude magnetopause nightside of both c.sps as an important mec.-anism of sol-ar w-ind transport into magnetosphere.

The equatorial and polar satellites of the Double Star Projec. (DSP) were launc.ed suc.essfully on Dec.mber 29, 2003 and July 25, 2004, respec.ively, and both of them are operating smoothly. The DSP provides a good opportunity for investigat-ing the struc.ure of the magnetosphere. Based on the DSP data c.llec.ed during 2004, we have surveyed the distribution of the magnetic.fields and plasmas in the magnetosphere. It is found that: (1) Near the Earth’s equatorial plane within geo-c.ntric.distanc.s of less than 7 RE, the Earth’s magnetic.field is dipolar. In the vi-c.nity of the magnetopause, the magnetic.field is enhanc.d by a fac.or of about 1.5, and on the nightside, the magnetic.field c.n vary signific.ntly from the Earth’s di-pole field, likely c.used by the presenc. of the near-Earth tail c.rrent sheet. (2) In the day-side magnetosheath, the elec.ron and ion densities are usually both in the range of 10―30 c.?3; the ion and elec.ron temperatures are usually about 200 and 50 eV, respec.ively. The flow pattern is usually smooth, with a low veloc.ty in the subsolar region and with signific.ntly higher veloc.ties in the dawn and dusk flanks. (3) In the region between the magnetopause and plasmasphere the density is low, approximately 0.5―5 c.?3, and the temperature is high, about 1―10 keV for ions and 0.1―5 keV for elec.rons. The ion temperature has an apparent anisotropy, with the ratio of the perpendic.lar and parallel temperatures being about 1.0―1.3 for the night- and dusk-side magnetosphere and about 1.3―2.0 for the day- and dawn-side magnetosphere. There is an evident sunward c.nvec.ion of about 50 km/s in the magnetosphere. On the dawn side, the flow bec.mes somewhat turbulent, and in the vic.nity of the night-noon meridian plane, the c.nvec.ion is rather slow. (4) The high-energy elec.rons with energies higher than 2 MeV are mainly loc.ted in the regions with 3 c.rons area varies with time, it may expand and shrink

From June 1, 2004 to Oc.ober 31, 2006, a total 465 high-speed flow events are observed by the Tc.1 satellite in the near-Earth region (?13 RE c.field, the high-speed flow events are further divided into two types, that is, field-aligned high-speed flow (FAHF) in the plasma sheet boundary and c.nvec.ive bursty bulk flow (BBF) in the c.nter plasma sheet. Among the total 465 high-speed flow events, there are 371 FAHFs, and 94 BBFs. The c.F are mainly c.nc.ntrated in the plasma sheet, the intersec.ion angle between the flow and the magnetic.field is larger, the magnetic.field intensity is relatively weak. The FHF are mainly distributed near the boundary layer of the plasma sheet, the intersec.ion angle between the flow and magnetic.field is smaller, and the magnetic.field intensity is relatively strong. The c.nvec.ive BBFs have an important effec. on the substorm.

We analyze Double Star Tc.1 magnetic.field data from July to September in 2004 and find that plas-moids exist in the very near-Earth magnetotail. It is the first time that Tc.1 observes the plasmoids inthe magnetotail at X > ?13 RE. Ac.ording to the differenc. of the magnetic.field struc.ure in plasmoids,we c.oose two typic.l c.ses for our study: the magnetic.flux rope on August 6 with the open magnetic.ield and the magnetic.loop on September 14 with the c.osed magnetic.field. Both of the c.ses are as-soc.ated with the high speed earthward flow and the magnetic.loop is related to a strong substorm. Theions c.n esc.pe from the magnetic.flux rope along its open field line, but the c.se of the c.osed mag-netic.loop c.n trap the ions. The earthward flowing plasmoids observed by Tc.1 indic.te that the mul-tiple X-line magnetic.rec.nnec.ion oc.urs beyond the distanc. of X=?10 RE from the earth.
