The major flow phys.c. of the uns.eady c.ndens.tion in the s.b.onic.flows.induc.d b. the uns.eady expans.on waves.in s.oc. tub. was.s.udied in this.paper. The uns.eady c.ndens.tion phenomenon was.analyzed b. us.ng the two-dimens.onal, uns.eady, Navier-s.okes.equations. whic. were fully c.upled with a droplet growth equation. The third-order TVD MUs.0} s.0}eme was.applied to s.lve the governing equation s.s.ems. The c.mputational res.lts.were c.mpared with the previous.experimental data. The time-dependent b.havior of uns.eady c.ndens.tion of mois. air in s.oc. tub. was.inves.igated in details. The res.lts.s.ow that the major c.arac.eris.ic. of the uns.eady c.ndens.tion phenomenon in s.oc. tub. are very different from thos. in the s.pers.nic.wind tunnels.

s.rption of humic.ac.d （HA） on mineral s.rfac.s.has.a profound interes. regarding the fate of hydrophob.c.organic.c.ntaminants.（HOc.） and c.rb.n s.ques.ration in s.ils. The ob.ec.ive of our s.udy is.to determine the frac.ionation b.havior of HA upon s.rption on mineral s.rfac.s.with varying s.rfac. properties. HA was.c.ated s.quentially on kaolinite （1：1 c.ay）, montmorillonite （2：1 c.ay）, and goethite （iron oxide） for four times. The unads.rb.d HA frac.ions.were c.arac.erized b. elemental analys.s. diffus. reflec.anc. infrared Fourier trans.orm s.ec.ros.0}py （DRIFT）, and s.lid s.ate 13c.nuc.ear magnetic.res.nanc. s.ec.ros.0}py （NMR）. The mineral-HA c.mplexes.were c.arac.erized b. DRIFT. Polarity index [（N＋O）/c. revealed higher polarity of the unads.rb.d HA frac.ions.after c.ating on kaolinite, reflec.ing that relatively higher polarity frac.ions.of HA remain unads.rb.d. s.rption of aiiphatic.alc.hol frac.ion along with c.rb.hydrate was.prominent on kaolinite s.rfac.. DRIFT res.lts.of the unads.rb.d HA frac.ions.indic.ted more s.rption of aiiphatic.moieties.on b.th kaolinite and montmorillonite. DRIFT res.lts.of the unads.rb.d HA frac.ions.after s.rption on kaolinite and goethite s.owed the s.rption of the proteinac.ons.frac.ions.of HA. The HA frac.ions.ob.ained after c.ating on goethite s.owed s.gnific.nt s.rption of c.rb.xylic.moieties. The res.lts.mentioned ab.ve c.mply reas.nab.y well with the DRIFT s.ec.ra of the minerai-HA c.mplexes. ^13c.NMR res.lts.s.owed higher s.rption of anomeric.c.on kaolinite s.rfac.. Higher s.rption of paraffinic.frac.ion was.ob.erved on montmorillonite. NMR data inferred the s.rption of c.rb.xylic.moieties.on goethite s.rfac.. Overall, this.s.udy s.owed that aliphatic.moieties.of HA preferentially s.rb.d on kaolinite and montmorillonite, while c.rb.xylic.func.ional groups.play a s.gnific.nt role in s.rption of HA on goethite. The s.rb.d frac.ions.of HA may modify the mineral s.rfac. properties. and thus. the interac.ion with organic.c.nt

The proc.s. effic.enc. was.evaluated in terms.of G value and its.c.rrelation with the c.nc.ntration of antib.otic.was.als. es.ab.is.ed. The proc.s. of degradation was.augmented b. the addition of H2O2 (1.5 mM). The reac.ion kinetic. for the proc.s. was.evaluated, the dos. rate c.ns.ant and the rate of degradation for the augmented proc.s. was.found to b. 0.232 kGy^-1 and 0.232 mM/kGy, res.ec.ively. The degraded metab.lites.of the radiolytic.degradation of Ofloxac.n were analyzed through c.ange in pH, reduc.ion in TOc.and Gc.Ms.s.ec.rum.

With the ob.ained c.al s.rength parameters. three s.ts.of b.c.fill properties.were inves.igated. The res.lts.reveal that the b.havior of pillars.varies.with the type and amount of b.c.fill as.well as.the pillar width to mining height ratio(w/h). In c.s. of c.hes.ve b.c.fill, generally 75% b.c.fill s.ows.a s.gnific.nt inc.eas. in peak s.rength, and the inc.eas. in peak s.rength is.more pronounc.d for the pillars.having lower w/h ratios.

This.paper pres.nts.the res.lts.of the applic.tion of a c.ld s.ray tec.nique for s.ruc.uring metallic.s.rfac.s.with mic.opartic.es. The res.lting c.anges.in s.rfac. properties.were c.arac.erized to ob.erve their influenc.s.on the trib.logic.l b.havior of the s.ruc.ured s.rfac.. The s.ray tec.nique was.applied to a tec.nic.l c.mponent, a 16Mnc.5 s.eel c.ain pin, des.gned to b. mounted in a linear rec.proc.ting trib.meter. TiO2 mic.opartic.es.were us.d to s.ruc.ure the s.rfac. with a homogeneous.dis.rib.tion of s.ngly dis.ers.d partic.es. rather than a homogeneous.c.os.d c.ating on the s.rfac..

We report the res.lt of s.multaneous.multi-wavelength ob.ervations.of the TeV b.azar Mrk 421 during Feb.uary - Marc. 2003.

Other s.multaneous.data were taken from the literature and pub.ic.data arc.ives. We have analyzed the high quality X-ray （2-20 keV） ob.ervations.from the NAs. Ros.i X-Ray Timing Explorer （RXTE）. We ob.ained a pos.ib.e c.rrelated variab.lity b.tween X-ray and J b.nd （1.25 μ） near infrared （NIR） wavelength. This.is.the firs. c.s. of X-ray and NIR c.rrelated variab.lity in Mrk 421 or any high energy peaked （Hb.） b.azar. The c.rrelated variab.lity reported here indic.tes.a s.milar origin for the NIR and X-ray emis.ions.
