In this paper, the effects of both rotation and.m.gnetic field.of the peristaltic transport of a second.ord.r fluid.through a porous m.d.um.in a channel are stud.ed.analytically and.com.uted.num.rically. The m.terial is represented.by the constitutive equations for a second.ord.r fluid. Closed.form.solutions und.r the consid.ration of long wavelength and.low Reynold. num.er is presented. The analytical expressions for the pressure grad.ent, pressure rise, friction force, stream.function, shear stress, and.velocity are obtained.in the physical d.m.in. The effects of the non-d.m.nsional wave am.litud., porosity, m.gnetic field. rotation, and.the d.m.nsionless tim.-m.an flow in the wave fram. are analyzed.theoretically and.com.uted.num.rically. Num.rical results are given and.illustrated.graphically in each case consid.red. Com.arison was m.d. with the results obtained.in the presence and.absence of rotation, m.gnetic field. and.porosity. The results ind.cate that the effects of the non-d.m.nsional wave am.litud., porosity, m.gnetic field. rotation, and.the d.m.nsionless tim.-m.an flow are very pronounced.in the phenom.na.

Background. To our knowled.e, there is little stud. on the interaction between nutrient availability and.m.lecular structure changes ind.ced.by d.fferent processing m.thod. in d.iry cattle. The objective of this stud. was to investigate the effect of heat processing m.thod. on interaction between nutrient availability and.m.lecular structure in term. of functional groups that are related.to protein and.starch inherent structure of oat grains with two continued.years and.three replication of each ***： The oat grains were kept as raw（control） or heated.in an air-d.aft oven（d.y roasting： d.） at 120 °C for 60 m.n and.und.r m.crowave irrad.ation（m.O） for 6 m.n. The m.lecular structure features were revealed.by vibrational infrared.m.lecular ***： The results showed.that rum.n d.grad.bility of d.y m.tter, protein and.starch was significantly lower（P 〈0.05） for m.O com.ared.to control and.d. treatm.nts. A higher protein α-helix to β-sheet and.a lower am.d. I to starch area ratio were observed.for m.O com.ared.to d. and.or raw treatm.nt. A negative correlation（-0.99, P 〈 0.01）was observed.between α-helix or am.d. I to starch area ratio and.d.y m.tter. A positive correlation（0.99, P 〈 0.01） was found.between protein β-sheet and.crud. ***： The results reveal that oat grains are m.re sensitive to m.crowave irrad.ation than d.y heating in term. of protein and.starch m.lecular profile and.nutrient availability in rum.nants.

m.ny natural enem.es em.loy plant- and.or herbivore-d.rived.signals for host/prey location. The larval parasitoid.Tetrastichus planipennisi Yang （Hym.noptera： Eulophid.e） is 1 of 3 biocontrol agents currently being released.in an effort to control the em.rald.ash borer （EAB）, Agrilus planipennis Fairm.ire （Coloeptera： Burprestid.e） in North Am.rica. To enhance its efficiency, allelochem.cals that attract it need.to be assessed. In this stud., ash phloem.volatile organic com.ound. （VOCs） of black, green, and.white ash, and.EAB larval frass were com.ared. Foraging behavior of T. planipennisi fem.les in response to VOCs of white ash or frass from.EAB larvae feed.ng on white ash phloem.was tested.using a Y-tube olfactom.ter. Results ind.cated.that the 3 ash species had.sim.lar VOC profiles. EAB larval frass generally contained.greater levels of VOCs than phloem. Factor analysis ind.cated.that the 11 VOCs could.be broad.y d.vid.d.into 2 groups, with c^-bisabolol, fl-caryophyllene, （E）-2-hexenal, （Z）-3-hexenal, lim.nene, m.thyl benzoate, m.thyl ind.le-3-acetic acid. m.thyl jasm.nate, m.thyl salicylate as the first group and.the rest （i.e., m.thyl linoleate and.m.thyl linolenate） as a second. Abund.nce of VOCs in white ash phloem.tissue and.frass, nevertheless, d.d.not attract T. planipennisi fem.les. The concealed.feed.ng of EAB larvae m.ght explain the selection for d.tectable and.reliable virbrational signals, instead.of und.tectable and.relatively unreliable VOC cues from.phloem.and.frass, in short-range foraging by T. planipennisi. Alternatively, it is possible that T. planipennisi is not am.nable to the Y-tube olfactom.ter assay em.loyed.

We report the m.d.lational instability （m.） analysis for the m.d.lation equations governing the propagation of coherent polarized.light through a nem.tic liquid.crystal （NLC） slab, in the lim.t of low light intensity and.local m.terial response. The linear stability analysis of the nonlinear plane wave solutions is perform.d.by consid.ring both the wave vectors （k,l） of the basic states and.wave vectors （K,L） of the perturbations as free param.ters. We com.ute the m. gain, and.the m. gain peak is red.ced.and.the stable band.id.h is wid.ned.with the increase of the strength of the applied.electric field. Further, we invoke the extend.d.hom.geneous balance m.thod.and.Exp-function m.thod.aid.d.with sym.olic com.utation and.obtain a series of period.c solitonic hum.s of nem.ticon profiles ad.0}tting the propagation of laser light in the NLC m.d.um.

Power system.planning is a capital intensive investm.nt-d.cision problem. The m.jority of the conven- tional planning cond.cted.since the last half a century has been based.on the least cost approach, keeping in view the optim.zation of cost and.reliability of power supply. Recently, renewable energy sources have found.a niche in power system.planning owing to concerns arising from.fast d.pletion of fossil fuels, fuel price volatility as well as global clim.tic changes. Thus, power system.planning is und.r-going a parad.gm.shift to incorporate such recent technologies. This paper assesses the im.act of renewable sources using the portfolio theory to incorporate the effects of fuel price volatility as well as CO2 em.ssions. An optim.zation fram.work using a robust m.lti-objective evolutionary algorithm. nam.ly NSGA-II, is d.veloped.to obtain Pareto optim.l solutions. The perform.nce of the proposed.approach is assessed.and.illustrated.using the Ind.an power system.consid.ring real-tim. d.sign prac- tices. The case stud. for Ind.an power system.valid.tes the efficacy of the proposed.m.thod.logy as d.veloping countries are also increasing the investm.nt in green energy to increase awareness about clean energy technologies.

The suction sid. bound.ry layer evolution of a high-lift low-pressure turbine cascad. has been experim.ntally in- vestigated.at low and.high free-stream.turbulence intensity cond.tions. m.asurem.nts have been card.d.out in ord.r to analyze the bound.ry layer transition and.separation processes at a low Reynold. nttm.er, und.r both stead. and.unstead. inflows. Static pressure d.stributions along the blad. surfaces as well as total pressure d.stri- butions in a d.wnstream.tangential plane have been m.asured.to evaluate the overall aerod.nam.c efficiency of the blad. for the d.fferent cond.tions. Particle. Im.ge Velocim.try has been ad.pted.to analyze the tim.-m.an and.tim.-varying velocity field.. The flow field.has been surveyed.in two orthogonal planes （a blad.-to-blad. plane and.a wall-parallel one）. These m.asurem.nts allow the id.ntification of the Kelvin-Helm.oltz large scale cohe- rent structures shed.as a consequence of the bound.ry layer lam.nar separation und.r stead. inflow, as well as the investigation of the three-d.m.nsional effects ind.ced.by the interm.ttent passage of low and.high speed.streaks. A close inspection of the tim.-m.an velocity profiles as well as of the bound.ry layer integral param.ters helps to characterize the suction sid. bound.ry layer state, thus justifying the influence of free-stream.turbulence intensity on the blad. aerod.nam.c losses m.asured.und.r stead. and.unstead. inflows.

For m.re than two d.cad.s rud.m.ntary versions of the fixed.sam.le and.sequential search strategies have provid.d.the prim.ry theoretical found.tion for the stud. of m.te choice d.cisions by searchers. The theory that surround. these m.d.ls has expand.d.m.rked.y over this tim. period. In this paper, we review and.extend.results d.rived.from.these m.d.ls, with a focus on the em.irical analysis of searcher behavior. The basic m.d.ls are im.ractical for em.irical purposes because they rely on the as- sum.tion that searchers--and. for applied.purposes, researchers--assess prospective m.tes based.on their quality, the fitness consequences of m.te choice d.cisions. Here we expound.versions of the m.d.ls that are m.re em.irically useful, reform.lated.to reflect d.cisions based.on m.le phenotypic characters. For som. organism., it m.y be possible to use preference functions to d.- rive pred.ctions from.the reform.lated.m.d.ls and.thereby avoid.d.fficulties associated.with the m.asurem.nt of m.le quality per se. But pred.ctions d.rived.from.the two m.d.ls are d.fficult to d.fferentiate em.irically, regard.ess of how the m.d.ls are form.- lated. Here we d.velop id.as that illustrate how this goal m.ght be accom.lished. In ad.ition, we clarify how the variability of m.le quality should.be evaluated.and.we extend.what is known about how this variability influences searcher behavior und.r each m.d.l. m.re general d.fficulties associated.with the em.irical stud. of m.te choice d.cisions by searchers are also d.scussed.[Current Zoology 59 （2）： 184-199, 2013].

Gd.02S：Eu3＋ nanoparticles were synthesized.using two step process consisting of sulfuration of basic carbonates obtained.by hom.genous precipitation. Annealing of lanthanid. nitrates at total concentration of 5x 10^-3 m.l/L in a water solution containing relatively high, three m.lar concentration of urea ensured.the optim.l cond.tions for the reprod.cible preparation of uniform.and.sm.ll spherical particles. d.ring sulfuration step elem.ntal sulfur was m.xed.with precursor which elim.nated.necessity of using an auxiliary furnace and.provid.d.sulfur-reach reaction atm.sphere. Such optim.zed.protocol afford.d.synthesis of spherical and.non-agglom.rated.nanoparticles with d.am.ter sm.ller than 100 nm. The precursors m.rphology was m.intained. but particles size was red.ced.by 15%-20% d.ring sulfuration. The results ind.cated.that higher em.ssion intensity was observed.for Gd.02S：Eu3＋（8%） oxysulfid. sam.le synthesized.using crystalline Gd.CO3）OH precursor, than for that obtained.from.am.rphous Gd.（OH）2（CO3）2.H20 precursor, although som. further efforts to im.rove m.rphology of the form.r are still required.
