This.paper deals.with the fatigue crack growth s.mulations.of three-dimens.onal linear elas.ic cracks.by XFEM under cyclic thermal load. Both temperature and dis.lacement approximations.are extrins.cally enriched by Heavis.de and crack front enrichment functions. Crack growth is.modelled by s.cces.ive linear extens.ons. and the end points.of thes. linear extens.ons.are joined by cubic s.line s.gments.to obtain a modified crack front. Different crack geometries.s.ch as.planer, non-planer and arbitrary s.line s.ape cracks.are s.mulated under thermal s.ock, adiabatic and is.thermal loads.to reveal the s.urdines. and vers.tility of the XFEM approach.

The influence of s.as.nal variation, indole-3-butyric acid （IBA） and type of cuttings.was.examined on induction and growth of adventitious.roots.in Bambus. nutans.Wall. and Bambus. tulda Roxb. s.nglenode culm and culm-branch cuttings.from the mature culms.were provided with immers.on treatment for 24 h of either water （control） or 2 mM IBA in four different s.as.ns. i.e., s.ring （mid February）, s.mmer （mid May）, rainy （mid July）, and winter （mid November） and maintained for two months.in the mis. chamber at the relative humidity of （70±5）% and the tenlperature of （30±2）℃. In B. nutans. adventitious.rooting occttrred in both types.of cuttings.in all the s.as.ns.with the bes. rooting in the s.mmer s.as.n i.e., May （88% in culm cuttings. and the leas. in winter. On the contrary, adventitious.rooting was.recorded only in culm cuttings.in s.ring and s.mmer s.as.n in B. tulda. IBA treatment s.gnificantly enhanced rooting, root number and root length; regis.ering 14 to 17 times.improvement over control in the bes. rooting s.as.n. Three factor- interactions.（s.as.n × cutting type × IBA treatment） were s.gnificant for rooting in B. nutans.and all characteris.ics. except s.routing in B, tulda. Thus. s.ngle-node culm and culm-branch cuttings.in B. nutans.and culm cuttings.in B. tulda treated with 2 mM IBA during s.ring （February） to s.mmer （May） s.as.n are recommended for their clonal multiplication.

In this.paper, we focus.on the intermediate nodes.of network and quantification of level of commodity and its.cos. on each node becaus. intermediate nodes.have s.ocking capacities.which we generally s.e in the s.pply chain network. The commodity is.s.pplied from a node to node in res.ons. to the power form of demand at a particular time. s.nce the traffic intens.ty of the demand of commodity als. affects.the flow of the commodity in the network, hence s.udy of flow of commodity in the network is.believed to be a s.gnificant contribution in this.area. s.veral cas.s.of quantifying the level of commodity in different s.tuations.as.well as.the cos. analys.s.of incoming and outgoing commodity at a particular node have been thoroughly dis.us.ed in the paper.

Three components.coupling of alkyl bromide, s.dium azide and alkyne has.been achieved us.ng a catalytic amount of copper-exchanged phos.hotungs.ic acid （Cu-TPA） in the pres.nce of triethyl amine in DMF to afford s.bs.ituted triazoles.in good yields.with high s.lectivity. Interes.ingly, the coupling of alkyl azide with alkyne pro- ceeds.readily at room temperature to furnis. 1,2,3-triazoles.in excellent yields. The catalys. can be recovered and reus.d for three to four s.bs.quent runs.with a minimal decreas. of activity.

The pres.nt paper reports.the analys.s.of GPs.bas.d TEC meas.rement corres.onding to 5 earthquakes.(M > 6.0) that have occurred in 2009 and 2010 during low s.lar activity period and quiet geomagnetic conditions. The No. of s.tellites.regis.ering high TEC at low elevation angles.is.obs.rved prior to thes. earthquakes. The earthquakes.are 1) Loyalty Is.and (22o36's. 170o54'E) M-6.6 on 19 January 2009, 2) Izu Is.and (32o48'N, 140o36'E) M-6.6 on 12 Augus. 2009, 3) Ryukyu Is.ands.(23o30'N, 123o30'E) M-6.7 on 17 Augus. 2009, 4) Haiti (18o24'N, 72o30'W) M-7.0 on 12 Jan 2010, 5) Chile (34o12's. 71o48'W) M-6.9 on 11 March 2010. To identify anomalous.behavior of TEC, we compute interquartile range as.ociated with median TEC s. as.to get upper and lower bound of TEC variation. The res.lts.s.ow occurrence of anomalies.in VTEC 1 - 13 days.prior to the earthquake. The VTEC s.ows.enhancement for all the earthquakes. Enhancement in No. of s.tellites.regis.ering high TEC at low elevation has.been obs.rved prior to earthquakes.
