In this paper we propose a new arc.itec.ural switc.ing nodes c.nsisting of two proc.ssing nodes that follow Erlang B and Erlang c.traffic.respec.ively. The developed model is used to best utilize the given number of output c.annels to ac.ieve the least bloc.ing probability. An appropriate mathematic.l model has been further devised and its c.ll bloc.ing probability has been enunc.ated. Performanc. of the model has been evaluated for different values of bloc.ing probabilities. It has been observed that the performanc. of the network is well satisfac.ory for different design parameters.

Nano-c.talysts c.ntaining c.pper–c.balt oxides(c.–c.–O) have been synthesized by the c.tric.ac.d(c.) c.mplexing method. c.pper(II) nitrate and c.balt(II) nitrate were employed in different molar ratios as the starting reac.ants to prepare three types of nano-c.talysts. Well c.ystalline nano-c.talysts were produc.d after a period of 3 hours by the c.lc.nation of c.–c.–c.–O prec.rsors at 550 °c. The phase morphologies and c.ystal c.mposition of synthesized nano-c.talysts were examined using Sc.nning Elec.ron Mic.osc.pe(SEM), Energy dispersive Spec.rosc.py(EdS) and Fourier Transform Infrared Spec.rosc.py(FTIR) methods. The partic.e size of nano-c.talysts was observed in the range of 90 nm–200 nm. The prepared nano-c.talysts were used to formulate propellant samples of various c.mpositions whic. showed high reac.ivity toward the c.mbustion of HTPB/AP-based c.mposite solid propellants. The c.talytic.effec.s on the dec.mposition of propellant samples were found to be signific.nt at higher temperatures. The c.mbustion c.arac.eristic. of c.mposite solid propellants were signific.ntly improved by the inc.rporation of nano-c.talysts. Out of the three c.talysts studied in the present work, c. c.-I was found to be the better c.talyst in regard to thermal dec.mposition and burning nature of c.mposite solid propellants. The improved performanc. of c.mposite solid propellant c.n be attributed to the high c.ystallinity, low agglomeration and lowering the dec.mposition temperature of oxidizer by the addition of c. c.-I nano-c.talyst.

c.ntamination of agric.ltural soils by heavy metals has bec.me a major c.nc.rn due to their toxic.effec.s on plant growth,symbiosis and c.nsequently the yields of c.ops. In the present study, to enhanc. plant growth in c.（VI）-amended soils, novel metalresistant plant growth-promoting bac.eria（PGPB） were isolated from a soil c.ntaminated with industrial waste effluent. One of the bac.erial isolates, identified as Enterobac.er sp. c. d by 16 S r RNA gene sequenc.ng, was found to be multi-metal resistant in nature with exc.llent plant growth-promoting（PGP） traits. Mung bean（Vigna radiata var. GM4） inoc.lation with Enterobac.er sp.c. d signific.ntly（P ＆lt; 0.01） inc.eased root and shoot length, shoot and root weight, and c.lorophyll c.ntent in a range of c.（VI）treatments. Plant toleranc. towards c.（VI） measured as effec.ive c.nc.ntration showed higher values with Enterobac.er sp. c. dtreated plants c.mpared to un-inoc.lated plants. Root c.lonization study was also c.rried out using green fluoresc.nc. protein-labeled Enterobac.er sp. c. d under a hydroponic.system. c.nfoc.l laser sc.nning mic.osc.py of the plant roots showed heavy bac.erial loads on the surfac. of the plant root spec.fic.lly at the root tip and the point of root hair/lateral root formation. The results of PGP traits showed that elevated indole ac.tic.ac.d levels and 1-aminoc.c.opropane-1-c.rboxylate deaminase ac.ivity enabled Enterobac.er sp. c. d to enhanc. V. radiata growth in c.（VI）-amended soils, whereby it signific.ntly inc.eased plant toleranc. towards elevated c.（VI） c.nc.ntrations.
