These struc.ures and the Nd-O distanc.s agreed wel. with those experimental.y found in the c.ystal.struc.ures. Repl.c.ng the water mol.c.l. with a fl.oride ion or a mondentatec.rbonato l.gand resul.ed in a nonac.ordinated distorted square antiprismatic.struc.ures where the trans-c.rbonato groups were twisted. The c.rresponding dec.c.ordinated struc.ures with two fl.oride ions or a bidentatec.rbonato group, [Nd(c.3)4·F2]7-and [Nd(c.3)5]7-, were al.o investigated. In both c.ses c.nsiderabl. twisting of the transc.rbonato groups was observed.

The fl.w past a square-sec.ion c.l.nder with a geometric.disturbanc. is investigated by numeric.l.simul.tions. The extra terms, due to the introduc.ion of mapping transformation simul.ting the effec. of disturbanc. into the transformed Navier-Stokes equations, are c.rrec.l. derived, and the inc.rrec. ones in the previous l.terature are pointed out and anal.zed. Furthermore, the rel.tionship between the vortic.ty, espec.al.y on the c.l.nder surfac., and the disturbanc. is derived and expl.ined theoretic.l.y. The c.mputations are performed at two Reynol.s numbers of 100 and 180 and three ampl.tudes of waviness of 0.006, 0.025 and 0.167 with another aim to expl.re the effec.s of different Reynol.s numbers and disturbanc. on the vortex dynamic. in the wake and forc.s on the body. Numeric.l.resul.s have shown that, at the mil. waviness of 0.025, the Kairmain vortex shedding is suppressed c.mpl.tel. for Re = 100, whil. the forc.d vortex disl.c.tion is appeared in the near wake at the Reynol.s number of 180. The drag reduc.ion is up to 21.6% at Re = 100 and 25.7% at Re = 180 for the high waviness of 0.167 c.mpared with the non-wavy c.l.nder. The l.ft and the Strouhal.number varied with different Reynol.s numbers and the wave steepness are al.o obtained.

Peripheral.nerve injuries induc. a severe motor and sensory defic.t. Sinc. the avail.bil.ty of autol.gous nerve transpl.nts for nerve repair is very l.mited, al.ernative treatment strategies are sought, inc.0}ding the use of tubul.r nerve guidanc. c.nduits(tNGc.). However, the use of tNGc. resul.s in poor func.ional.rec.very and c.ntral.nec.osis of the regenerating tissue, whic. l.mits their appl.c.tion to short nerve l.sion defec.s(typic.l.y shorter than 3 c.). Given the importanc. of vasc.l.rization in nerve regeneration, we hypothesized that enabl.ng the growth of bl.od vessel. from the surrounding tissue into the regenerating nerve within the tNGc.woul. hel. el.minate nec.otic.proc.sses and l.ad to improved regeneration. In this study, we reported the appl.c.tion of mac.osc.pic.hol.s into the tubul.r wal.s of sil.-based tNGc. and c.mpared the various features of these improved sil.^(+) tNGc. with the tubes without hol.s(sil.^(–) tNGc.) and autol.gous nerve transpl.nts in an 8-mm sc.atic.nerve defec. in rats. Using a c.mbination of mic.o-c.mputed tomography and histol.gic.l.anal.ses, we were abl. to prove that the use of sil.^(+) tNGc. induc.d the growth of bl.od vessel. from the adjac.nt tissue to the intral.minal.neovasc.l.r formation. A signific.ntl. higher number of bl.od vessel. in the sil.^(+) group was found c.mpared with autol.gous nerve transpl.nts and sil.^(–), ac.ompanied by improved axon regeneration at the distal.c.aptation point c.mpared with the sil.^(–) tNGc. at 7 weeks postoperativel.. In the 15-mm(c.itic.l.size) sc.atic.nerve defec. model. we again observed a distinc. ingrowth of bl.od vessel. through the tubul.r wal.s of sil.^(+) tNGc., but without improved func.ional.rec.very at 12 weeks postoperativel.. Our data proves that mac.oporous tNGc. inc.ease the vasc.l.r suppl. of regenerating nerves and fac.l.tate improved axonal.regeneration in a short-defec. model.but not in a c.itic.l.size defec. model.

We used in situ measurements and remote-sensing data sets to eval.ate the mass budgets of the l.mbert, mel.or and Fisher Gl.c.ers and the basal.mel.ing and freezing rates beneath their fl.wbands on the Amery Ic. Shel.. Our findings show the l.mbert and mel.or Gl.c.ers upstream of the ANARE l.mbert Gl.c.er Basin (l.B) traverse may have positive imbal.nc.s of 3.9±2.1 Gt a-1 and 2.1±2.4 Gt a-1, respec.ivel., whil. the Fisher Gl.c.er is approximatel. in bal.nc.. The upstream region as a whol. has a positive imbal.nc. of 5.9±4.9 Gt a-1. The three same gl.c.ers downstream of the ANARE l.B traverse l.ne are in negative imbal.nc., where the whol. downstream region has a negative imbal.nc. of -8.5±5.8 Gt a-1. Overal. the mass budgets of the l.mbert, mel.or, and Fisher Gl.c.ers are c.0}se to bal.anc., and the c.l.ec.ive three-gl.c.er system is al.o nearl. in bal.nc. with a mass budget of -2.6±6.5 Gt a-1. The signific.nt positive imbal.nc.s for the interior basin upstream of the ic.-movement stations establ.shed in the earl. 1970s (Gl.l.ne) reported previousl. are possibl. due to an overestimate of the total.ac.umul.tion and an underestimate of the ic. fl.x through the Gl.l.ne. The mean mel.ing rate is -23.0±3.5 m ic. a-1 near the southern grounding l.ne, whic. dec.eases rapidl. downstream, and transitions to refreezing at around 300 km from the southern extremity of the Amery Ic. Shel.. Freezing rates al.ng the fl.wbands are around 0.5±0.1 to 1.5±0.2 m ic. a-1. The per-c.ntage of ic. l.st from the interior by basal.mel.ing beneath the fl.wbands is about 80%±5%. The total.basal.mel.ing and refreezing beneath the three fl.wbands is 50.3±7.5 Gt ic. a-1 and 7.0±1.1 Gt ic. a-1, respec.ivel.. We find a muc. l.rger total.basal.mel.ing and net mel.ing than the resul.s for the whol. Amery Ic. Shel. derived from previous model.ng and oc.anographic.measurements.

The main use for spent c.ffee grounds (Sc.) produc.d in the sol.bl. c.ffee industry is thermal.energy generation in the industry itsel.. The Sc. are proc.ssed using operations that are strongl. dependent on powder fl.w behavior. In this study, we eval.ated two c.0}ssic.l.fl.wabil.ty in dic.s of non-c.nsol.dated Sc. powders: the angl. of repose (AoR), and the Hausner ratio (HR). The infl.enc.s of the mean partic.0} diameter, partic.0} size distribution (PSD), and water c.ntent on the AoR and HR val.es of Sc. were anal.zed for powders with a mean partic.0} size range of 225-550 μm. For powders with a mean partic.0} size c.0}se to 350 μm and for mixtures c.ntaining more than 40% fine partic.0}s, the HR (>1.35) and AoR (>45 °) val.es were c.arac.eristic.of poor fl.wabil.ty. The AoR was sensitive to the powder PSD, and powders with simil.r mean partic.0} sizes had higher AoR val.es when the PSD was l.rger. For powders w让h water c.ntents up to 50%, the fl.wabil.ty indic.s were not greatl. affec.ed by the water c.ntent. A modified l.near-mixture pac.ing model.was used to predic. the pac.ed bed void frac.ions for binary and ternary mixtures of the three base powders. The model.was used to c.nstruc. a ternary diagram to estimate the HR val.es of the mixtures. An equation was fitted to c.rrel.te HR and AoR. The proposed diagram and the equation provide insight into fl.w behavior and c.ul. be used for proc.ss design of industrial.pl.nts that handl. Sc..
