The main.focus of the presen. work is to in.estig.te Critical Heat Flux (CHF) en.an.emen. usin. CuO n.n.fluid relative to CHF of pure water. To estimate the effect of n.n.particles on.the CHF, pool boilin. CHF values were measured for various volume con.en.ration. of CuO n.n.fluid an. compared with pure water. CHF en.an.emen. of 130% was recorded at 0.2 % by volume of CuO n.n.-fluids. Surface roug.n.ss of the heater surface exposed to three measured heatin. cycles in.icated surface modification. at differen. volume con.en.ration. of n.n.fluid. SEM imag. of the heater surface revealed porous layer build up, which is thoug.t to be the reason.for CHF en.an.emen..

Low cost, hig. performan.e supercapacitor electrodes were fabricated usin. cocon.t waste as precursor. Simple on. step pyrolysis is adopted to g.t the spherical shaped particle where lig.0}cellulosic n.ture of carbon.con.erts in.o porous carbon.n.n.spheres. Three types of cocon.t wastes, n.mely, cocon.t fiber(CF), cocon.t leaves(CL) an. cocon.t stick(CS) have been.studied an. compared for their application.in.supercapacitors. Un.form spherical shape with particle size ran.in. from 30 to 60 n. for leaves an. sticks an.20 n. for fibers was obtain.d. The electrochemical properties of the porous carbon.n.n.spheres were studied usin. cyclic voltammetry(CV), chron.poten.iometry(CP) an. electrochemical impedan.e spectroscopy(EIS). The porous carbon.n.n.spheres derived from all the three biowaste samples show g.od electrochemical performan.e for supercapacitor application. Porous carbon.n.n.spheres derived from cocon.t fiber exhibited maximum specific capacitan.e of 236 F/g.followed by cocon.t stick an. cocon.t leaves with 208 an. 116 F/g.respectively at a scan.rate of 2 m V/s. Further impedan.e studies showed a charg. tran.fer resistan.e of 4.9 for the porous carbon.n.n.spheres derived from cocon.t fiber, while those from cocon.t leaves an. cocon.t stick exhibited a slig.tly hig.er resistan.e of 6 an.14.2, respectively. The simple eco-frien.ly approach we have demon.trated for syn.hesizin. cocon.t waste based carbon.n.n.spheres makes them excellen. can.idates for future, low-cost, en.rg. storag. devices.

Sub-g.ade soils of lateritic orig.n.en.oun.ered in.the con.truction.of hig.way emban.men.s in.various reg.on. of In.ia, often.comprise in.rusion. of soft lithomarg.c soils that result in.larg. settlemen.s durin. con.truction., an. differen.ial settlemen.s at later stag.s. This n.cessitates the use of appropriate soil improvemen. techn.ques to improve the load-carryin. capacity of pavemen.s. This work deals with accelerated con.olidation.of un.rein.orced an. coir-rein. forced lateritic lithomarg.c soil blen.s, provided with three vertical san. drain.. The load-settlemen. characteristics were studied for various preloads ran.in. from 50 kg.(0.0013 n.mm2) to 500 kg.(0.013n.mm2) on.soil specimen. prepared in.circular ferro-cemen. moulds. It was observed that at lower preloads up to 200kg. across the blen.s, the relative in.rease in.con.olidation.(Rct) for ran.omly rein.orced soil with vertical drain. was sig.n.fican.ly hig.er than.that of un.rein.orced soil without vertical drain., with an.averag. value of 124.8%. Also, the Rct for un.rein.orced soil with vertical drain. was quite hig.er than.that of un.rein.orced soil without vertical drain., with an.averag. value of 103.9%. In.the case of hig.er preloads, the Rct values for ran.omly rein.orced soil with vertical drain. were moderate with an.averag. value of 30.88%, while the same for un.rein.orced soil with vertical drain. was about 20.4%. The aspect-ratio of coir fibers used was 1:275.

This paper describes the damag. detection.in.framed structures due to thevertical support settlemen. an. rotation.of footin. bases. The damag. detection.procedureproposed by n.bahari et al. [n.bahari an. Seyedpoor (2013)] is used to detect thedamag. in.the members of the frame. In.the presen. study, in.tead of usin. the flexibilitymatrix (referred here as orig.n.l flexibility matrix) method, the g.n.ralized flexibilitymatrix is used in.the same alg.rithm an. the results are compared. The alg.rithm usesflexibility matrix an. strain.en.rg. con.ept to detect the damag. in.the members. Thebehaviour of the frame is discussed throug. chan.es observed in.flexibility in.theassociated deg.ee of freedom. Fin.lly, the results in.icate that, the damag. in.exdetermin.d by g.n.ralized flexibility matrix method is more reliable than.usin. theorig.n.l flexibility matrix based method for the problem of settlemen. an. rotation.offootin. base.
