Unders.anding the movement of animals.is.fundamental to population and community ecology. His.orically, it has.been difficult to quantify movement patterns.of mos. fis.es. but technological advances.in acous.ic telemetry have increas.d our abilities.to monitor their movement. In this.s.udy, we combined s.all-s.ale active acous.ic tracking with large-s.ale pas.ive acous.ic monitoring to develop an empirical movement model for s.xgill s.arks.in Puget s.und, WA, Us.. We began by tes.ing whether a correlated random walk model des.ribed the daily movement of s.xgills. however, the model failed to capture home-ranging behavior. We added this.behavior and us.d the res.ltant model （a bias.d random walk model） to determine whether daily movement patterns.are able to explain large-s.ale s.as.nal movement. The daily model did not explain the larger-s.ale pat- terns.of movement obs.rved in the pas.ive monitoring data. In order to create the large-s.ale patterns. s.xgills.mus. have per- formed behaviors.（large, fas. directed movements. that were unobs.rved during s.all-s.ale active tracking. In addition, s.as.nal s.ifts.in location were not captured by the dally model. We added thes. ＇unobs.rved＇ behaviors.to the model and were able to capture large-s.ale s.as.nal movement of s.xgill s.arks.over 150 days. The development of empirical models.of movement al- lows.res.archers.to develop hypothes.s.and tes. mechanis.s.res.ons.ble for a s.ecies.movement behavior and s.atial dis.ribution. This.knowledge will increas. our ability to s.cces.fully manage s.ecies.of concern [Current Zoology 58 （1）： 103-115, 2012].

International j.urnal of Minerals.Metallurgy and Materials 2013年第4期20卷 329-337页

作者： j. Pal s. Ghorai M. C. Gos.ami D. Ghos. D. Bandyopadhyay s. Ghos. Cs.R-National Metallurgical Laboratory Department of Metallurgical and Material Engineering Jadavpur University

Lump lime as.a fiux material in a bas.c oxygen furnace （BOF） often creates.problems.in operation due to its.high melting point, poor dis.olution property, hygros.opic nature, and fines.generation tendency. To alleviate thes. problems. fluxed lime iron oxide pellets.（FLIP） containing 30% CaO were developed in this.s.udy us.ng was.e iron oxide fines.and lime. The s.itable handling s.rengths.of the pellet （crus.ing s.rength： 300 N; drop s.rength： 130 times. of FLIP were developed by treating with CO2 or indus.rial was.e gas.at room temperature, while no s.parate binders.were us.d. When the pellet was.added into hot metal bath （carbon-containing molten iron）, it was.decompos.d, melted, and trans.ormed to produce low melting oxidizing s.ag, becaus. it is.a combination of main CaO and Fe2O3. This.s.ag is.s.itable for facilitating P and C removal in refining. Furthermore, the pellet enhances.was.e utilization and us. of CO2 in was.e gas. In this.article, emphas.s.is.given on s.udying the behavior of thes. pellets.in hot metal bath during melting and refining along with thermodynamics.and kinetics.analys.s. The obs.rved behaviors.of the pellet in hot metal bath confirm that it is.s.itable and beneficial for us. in BOF and replaces.lump lime.

A nonlinear optical s.ngle crys.al of potas.ium pentaborate tetrahydrate （KB5O8·4H2O） has.been grown from aqueous.s.lution by us.ng unidirectional crys.al growth method of s.nkaranarayanan-Ramas.my （s.） with a due modification in the growth as.embly.

引用

International j.urnal of Biomathematics 2015年第4期8卷 205-235页

The effect of permeable walls.and magnetic field on the peris.altic flow of a Carreau fluid in a tapered as.mmetric channel is.s.udied. The tapered as.mmetric channel is.normally created due to the intra-uterine fluid flow induced by myometrial contractions.and it was.s.mulated by as.mmetric peris.altic fluid flow in a two-dimens.onal infinite non-uniform channel. The analys.s.has.been performed under long wavelength and low- Reynolds.number as.umptions.to linearize the governing flow equations. A s.ries.s.lution in res.ect of a s.all Weis.enberg number is.obtained for the s.ream function, axial pres.ure gradient and s.ear s.res.. Time average of pres.ure ris. and frictional force on the upper wall has.als. been computed us.ng numerical integration. The res.lts.have been pres.nted graphically for the various.interes.ed phys.cal parameters. It is.obs.rved that for Carreau fluids.the peris.als.s.works.as.a pump agains. a greater pres.ure ris. compared with a Newtonian fluid, while there exis.s.no s.gnificant difference in free pumping flux for Newtonian and Carreau fluids.in the tapered as.mmetric channel.

We s.udy the nonlocality dynamics.for two models.of atoms.in cavity quantum electrodynamics.（QED）; the firs. model contains.atoms.in a s.ngle cavity undergoing neares.-neighbor interactions.with no initial correlation, and tile s.cond contains.atoms.confined in n different and noninteracting cavities. all of which were initially prepared in a maximally correlated s.ate of n qubits.corres.onding to the atomic degrees.of freedom. The nonlocality evolution of the s.ates.in the s.cond model s.ows.that the corres.onding maximal violation of a multipartite Bell inequality exhibits.revivals.at precis. times. defining, nonlocality s.dden deaths.and nonlocality s.dden rebirths. in analogy with entanglement. Thes. quantum correlations.are provided analytically for the s.cond model to make the s.udy more thorough. Differences.in the firs. model regarding whether the array of atoms.ins.de the cavity is.arranged in a periodic or open fas.ion are crucial to the generation or redis.ribution of quantum correlations. This.contribution paves.the way to us.ng the nonlocality multipartite correlation meas.re for des.ribing the collective complex behavior dis.layed by s.ightly interacting cavity QED arrays.

The s.ort-term influence of dung depos.tion and the further redis.ribution of dung by dung beetles.were s.udied under a res.ing place of the red howler monkey （Alouatta s.niculus. living in tropical ralnfores.s.of s.uth America. Monkey dung was.experimentally clumped on the field in a place us.d by troops.of howler monkeys.for res.ing in the Nouragues.Res.rve s.ation, French Guiana. Dung-treated plots.were s.mpled s.rially over three weeks.and compared with controls.located in their immediate vicinity. The compos.tion of the s.il matrix （top 10 cm） was.s.udied in s.cces.ive microlayers.us.ng an optical method. Under the influence of dung beetle activity, the tops.il became more homogeneous.by los.ng its.litter, its.content in earthworm faeces.increas.d in the cours. of time, and s.rface mineral depos.ts.were penetrated by roots. The res.lts.were interpreted in the light of pres.nt knowledge on the effects.of s.il animal activity on plant growth and s.rvival of s.edlings.
