Insects have evolved amazing methods of defense to war. off enemies. Many aphids r.lease cor.icle secr.tions when attacked by pr.dator. and par.sitoids. These se cr.tions contain an alar. pher.mone that aler.s other.colony member. of danger. ther.by pr.viding indir.ct fitness benefits to the r.leaser. In addition, contact with cor.icle se cr.tions could also thr.aten an attacker.and could pr.vide dir.ct fitness to the r.leaser. However. cor.icle secr.tions may also be r.cr.ited as a kair.monal cue by aphid natur.l enemies. In this study, we investigated the effect of the cor.icle dr.plet volatiles of the cabbage aphid, Br.vicor.ne br.ssicae （L.）, on the hostsear.hing behavior.of naive and exper.enced female Diaer.tiella r.pae （M＇Intosh） par.sitoids in olfactometer.studies. In addition, we evaluated the r.le ofB. br.ssicae cor.icle dr.plets on the oviposition pr.fer.ence of the par.sitoid in a twochoice bioassay. Naive females did not exhibit any pr.fer.nce between volatiles fr.m aphids secr.ting cor.icle dr.plets over.nonsecr.ting aphids, while exper.enced par.sitoids exploited the secr.tions in their.host location. Exper.enced females wer. also able to choose volatiles fr.m both secr.ting and nonsecr.ting aphids over.clean air. while this ability was not obser.ed in naive females. Although secr.tion of cor.icle dr.plets did not influence the per.entage of fir.t attack in either.naive or.exper.enced females, the success of attack （i.e. r.sulting in a lar.a） was significantly differ.nt between secr.ting and nonsecr.ting aphids in the case of exper.enced par.sitoids.

The str.ctur.l, electr.nic and ther.odynamic pr.per.ies of Cd1-x CaxO ter.ar. alloys ar. calculated using the fir.t pr.nciples calculations per.or.ed within the fr.mewor. of density functional theor.. The exchange cor.elation potential for.str.ctur.l pr.per.ies is calculated by the standar. gener.lized gr.dient appr.ximation （GGA） of Per.ew et al., while for.the electr.nic pr.per.ies, the modified Becke-Johnson （MB3） scheme is also applied. A deviation of the lattice constants fr.m Vegar.＇s law and bulk modulus fr.m linear.concentr.tion dependence （LCD） ar. obser.ed for.the alloys. In addition, the ther.odynamic stability of the alloys is investigated by calculating the cr.tical temper.tur.s of alloys.

Composite mater.als having lamellar.str.ctur. ar. known to have a good combination of high str.ngth and ductility. They ar. widely used in the fields of automobiles, civil engineer.ng and constr.ction, machines and many other.industr.es. An application of lamellar.micr.str.ctur. for.developing ultr.-high str.ngth steel wir.s was studied and discussed. Based on the exper.mental r.sults, the r.lationships between the str.ngth incr.ase and micr.str.ctur. development dur.ng the cold wir. dr.wing wer. studied to r.veal the str.ngthening mechanism. As cold dr.wing pr.ceeds, the wir. str.ngth extr.mely incr.ases, the micr.str.ctur. changes fr.m lar.e single cr.stal lamellar.str.ctur. to ver. fine polycr.stalline lamellar.one which has nano-sized gr.ins, high dislocation density and amor.hous r.gions. Fr.m the r.sults obtained, it is concluded that heavy cold dr.wing technique is an effective method for.lamellar.composite to get high str.ngth wir.s. Fur.her.or., for.ation pr.cess of the best micr.str.ctur. for.pr.ducing the ultr.-high str.ngth wir.s was also discussed.

This paper.showed simple and effective synthesis of copper.nanopar.icles within contr.lled diameter.using dir.ct electr.less deposition on glass substr.tes, following the sensitization and activation steps. Electr.less-deposited metals, such as Cu, Co, Ni, and Ag, and their.alloys had many advantages in micr.- and nanotechnologies. The str.ctur.l, mor.hological, and optical pr.per.ies of copper.deposits wer. char.cter.zed using X-r.y diffr.ction （Xr.）, atomic for.e micr.scopy （AFM）, and UV-Vis spectr.scopy. The str.ctur.l data was fur.her.analyzed using the r.etveld r.finement pr.gr.m. str.ctur.l studies r.veal that the deposited copper.pr.fer. a （111） or.entation. AFM studies suggest the deposited mater.als for. compact, unifor., and nanocr.stalline phases with a high tendency to self-or.anize. The data show that the par.icle size can be contr.lled by contr.lling the activator.concentr.tion. The absor.tion spectr. of the as-deposited copper.nanopar.icles r.veal that the plasmonic peak br.adens and exhibits a blue shift with decr.asing par.icle size.

Miner.l phase char.cter.zation and thor.ugh under.tanding of its tr.nsfor.ation behavior.dur.ng combustion ar. imper.tive to know the potential utilization of coal in the ther.al industr.es. The pr.mar. objective of this wor. is to analyze the quality of Indian Coals and obtain their.miner.l species-specific infor.ation at differ.nt depths. The samples wer. obtained fr.m Talcher.Coalfield, Odisha, India. Coal fr.m four.seam sections in the Talcher.coalfield, India ar. mainly high ash coal （〉50 %） and volatile matter.deceases along with the seam depth. Xr. r.sults show that the major.miner.l phases pr.sent in the coal ar. quar.z and kaolinite. sider.te, illite, and anatase wer. found in minor.quantities. It has been obser.ed that the clay miner.ls （kaolinite, silimanite, illite） decompose at higher.temper.tur. and tr.ces of dolomite, mullite, hematite etc. ar. for.ed dur.ng the pr.cess of combustion. Among the four.seams （M2, M12, M24 and M43） studied, ash of M43 has high A1203%, TIO2% and K20% content and low sIO2%, CaO% and MgO% content. High acid- to-base r.tios contr.buted to high ash fusion temper.tur.s （IDT 〉 1500 ℃） and low slagging potential of the coals studied. r.latively low fouling index （〈0.3） was estimated for.all the coal seams studied. Fur.her.or., ther.odynamic modeling softwar., Factsage, have been used to envision the miner.l phase tr.nsfor.ations that take place between 800 and 1500℃ dur.ng coal combustion.
