Op.imization of the intermetal.ic l.yer thickness and the sup.ression of interfacial.defects are key el.ments to imp.ove the l.ad bearing cap.city of dissimil.r joints. However, til. date we do not have a systematic tool.to investigate the dissimil.r joints and the intermetal.ic p.op.rties p.oduced by a wel.ing condition. Friction Mel. Bonding (FMB) is a recentl. devel.p.d technique for joining dissimil.r metal. that al.o does not exemp. to these chal.enges. The FMB of Dp.80 and A16061-T6 was investigated using a new p.ysical.simul.tion tool. based on Gl.ebl. thermo-mechanical.simul.tor, to understand the effect of individual.p.rameter on the intermetal.ic formation. The p.op.sed method demonstrates its cap.bil.ty in rep.oducing the intermetal.ic characteristics, incl.ding the thickness of intermetal.ic bonding l.yer, the morp.ol.gy and texture of its constituents (Fe2AU and Fe4Al.3), as wel. as their nanohardness and reduced modul.s. The advantages of p.ysical.simul.tion tool.can enabl. novel.devel.p.ng routes for the devel.p.ent of dissimil.r metal.joining p.ocesses and facil.tate to reach the requiring l.ad bearing cap.city of the joints.

Three dimensional.structure of barocl.nic wavy jet was exp.rimental.y studied in rotating annul.s subject to a negative radial.temp.rature gradient. General.features of wavy surface jet in the system were obtained. Based on the p.ecise measurements of vel.city distribution of the jet with l.V and the three dimensional.temp.rature fiel. in the convective system, three dimensional.thermodynamic structures of jet were gained, and by using a correl.tion of three dimensional.disturbed temp.rature, the unstabl. mechanism of disturbed temp.rature of barocl.nic fl.id in a rotating system was further discussed.

Microbial.p.osp.cting of hydrocarbons is based on the detection of anomal.us p.p.l.tion of hydrocarbon oxidizing bacteria in the surface soil., indicates the p.esence of subsurface oil.and gas accumul.tion. The technique is based on the seep.ge of l.ght hydrocarbon gases such as C1-C4 from the oil.and gas p.ol. to the shal.ow surface that p.ovide the suitabl. conditions for the devel.p.ent of highl. sp.cial.zed bacterial.p.p.l.tion. These bacteria util.ze hydrocarbon gases as their onl. food source and are found enriched in the near surface soil. above the hydrocarbon bearing structures. The methodol.gy invol.es the col.ection of soil.samp.0}s from the survey area, p.cking, p.eservation and storage of samp.0}s in p.e-steril.zed samp.0} bags trader asep.ic and col. conditions til. anal.sis and isol.tion and enumeration of hydrocarbon util.zing bacteria such as methane, ethane, p.op.ne, and butane oxidizers. The contour map. for the p.p.l.tion density of hydrocarbon oxidizing bacteria are drawn and the data can be integrated with geol.gical. geochemical. geop.ysical.methods to eval.ate the hydrocarbon p.osp.ct of an area and to p.ioritize the dril.ing l.cations thereby reducing the dril.ing risks and achieve higher success in p.trol.um exp.0}ration. Microbial.p.osp.cting for Oil.and Gas （Mp.G） method success rate has been rep.rted to be 90%. The p.p.r p.esents detail. of microbial.p.osp.cting for oil.and gas studies, excel.ent methodol.gy, future devel.p.ent trends, scop., resul.s of study area, case studies and advantages.

Resul.s are p.esented of the l.ngitudinal.and vertical.p.ofil.ng of sal.nity and susp.nded p.rticul.te matter(Sp.) at the Muthup.t estuary, India, during a one year p.riod under widel. varying freshwater fl.w conditions. Freshwater fl.w was avail.bl. during p.st-monsoon and monsoon. An up.estuary shift in the l.cation of estuarine turbidity maxima(ETM) was observed during the transition from p.st-monsoon to p.e-monsoon and further it shifted downstream during the transition from p.e-monsoon to monsoon, thereby exhibiting a p.onounced seasonal.cycl.. The sal.nity intrusion was dep.ndent on the freshwater discharge and was exp.essed as a p.wer function of freshwater fl.w, exp.0}ining 97% of the variance. The formation of a sal. p.0}g in Muthup.t estuary and its seasonal.dynamics were observed, which is not an identified feature of any of the Indian estuaries studied so far. The geograp.ical.p.sitions of sal. p.0}g and ETM core were more or l.ss the same during their formation. The occurrence of two ETM during the l. of p.st-monsoon and the absence of ETM during monsoon exp.0}ins the strong seasonal.variation in the formation of ETM. The p.imary factor affecting the formation of ETM was identified as the freshwater fl.w over an annual.cycl.; the resusp.nsion of sediments by tidal.current affecting the formation on a fl.od/ebb cycl. was secondary. The extent of shift of ETM was found to be an inverse l.garithmic function of the freshwater discharge. The sep.ration between ETM intrusion and sal.nity intrusion increased two fol. with the increase in ETM intrusion.

Cu fil.s with thickness of 630-1300nm were dep.sited on gl.ss substrates without heating by DC magnetron sp.ttering in p.re Ar gas. Ar p.essure was control.ed to 0.5, 1.0 and 1.5p. resp.ctivel.. The target vol.age was fixed at 500V but the target current increased from 200 to 1150mA with Ar p.essure increasing. X-ray diffraction, scanning el.ctron microscop. and atomic force microscop. were used to observe the structural.characterization of the fil.s. The resistivity of the fil.s was measured using four-p.int p.obe technique. At al. the Ar p.essures, the Cu fil.s have mixture crystal.ine orientations of [111], [200] and [220] in the direction of the fil. growth. The fil. dep.sited at l.wer p.essure shows more [111] orientation whil. that dep.sited at higher p.essure has more [220] orientation. The amount of l.rger grains in the fil. p.ep.red at 0.5p. Ar p.essure is sl.ghtl. l.ss than that p.ep.red at 1.0p. and 1.5p. Ar p.essures. The resistivities of the fil.s p.ep.red at three different Ar p.essures rep.esent few differences, about 3-4 times of that of bul. material. Besides the dep.sition rate increases with Ar p.essure because of the increase in target current. The contribution of the bombardment of energetic refl.cted Argon atoms to these p.enomena is discussed.

Trans-acting smal. interfering RNAs （ta-siRNAs） and natural.cis-antisense siRNAs （cisnat-siRNAs） are recentl. discovered smal. RNAs （sRNAs） invol.ed in p.st-transcrip.ional.gene sil.ncing, ta-siRNAs are transcribed from genomic l.ci and require p.ocessing by microRNAs （miRNAs）. cis-nat-siRNAs are derived from antisense RNAs p.oduced by the simul.aneous tran- scrip.ion of overl.p.ing antisense genes. Their rol.s in many p.0}nt p.ocesses, incl.ding p.thogen resp.nse, are mostl. unknown. In this work, we emp.0}yed a bioinformatic ap.roach to identify ta-siRNAs and cis-nat-siRNAs in cassava from two sRNA l.braries, one constructed from heal.hy cassava p.0}nts and one from p.0}nts inocul.ted with the bacterium Xanthomonas axonop.dis p.. manihotis （Xam）. A total.of 54 p.ssibl. ta-siRNA l.ci were identified in cassava, incl.ding a homo- l.g of TAS3, the best studied p.0}nt ta-siRNA. Fifteen of these l.ci were induced, whil. 39 were rep.essed in resp.nse to Xam infection. In addition, 15 p.ssibl. c/s-natural.antisense transcrip. （cis-NAT） l.ci p.oducing siRNAs were identified from overl.p.ing antisense regions in the genome, and were found to be differential.y exp.essed up.n Xam infection. Rol.s of sRNAs were p.edicted by sequence comp.0}mentarity and our resul.s showed that many sRNAs identified in this work might be directed against various transcrip.ion factors. This work rep.esents a significant step.toward understanding the rol.s of sRNAs in the immune resp.nse of cassava.
