Background： To our knowledge, there is little study on the interaction between nutrient availability and m.lecular structure changes induced by different processing m.thods in dairy cattle. The objective of this study was to investigate the effect of heat processing m.thods 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-draft oven（dry roasting： dO） at 120 °C for 60 m.n and under m.crowave irradiation（m.O） for 6 m.n. The m.lecular structure features were revealed by vibrational infrared m.lecular ***： The results showed that rum.n degradability of dry m.tter, protein and starch was significantly lower（P 〈0.05） for m.O com.ared to control and dO treatm.nts. A higher protein α-helix to β-sheet and a lower am.de I to starch area ratio were observed for m.O com.ared to dO and/or raw treatm.nt. A negative correlation（-0.99, P 〈 0.01）was observed between α-helix or am.de I to starch area ratio and dry m.tter. A positive correlation（0.99, P 〈 0.01） was found between protein β-sheet and crude ***： The results reveal that oat grains are m.re sensitive to m.crowave irradiation than dry heating in term. of protein and starch m.lecular profile and nutrient availability in rum.nants.

The accuracy of num.rical sim.lations and m.ny other m.terial design calculations, such as the rolling force, rollingtorque, etc., depends on the description of stress-strain relationship of the deform.d m.terials. One com.on m.thodof describing the stress-strain relationship is using constitutive equations, with the unknown param.ters fitted byexperim.ntal data obtained via plane strain com.ression (PSC). due to the highly nonlinear behaviour of the constitutive equations and the noise included in the PSC data, determ.nation of the m.del param.ters is difficult. Inthis paper, genetic algorithm. were exploited to optim.se param.ters for the constitutive equations based on thePSC data. The original PSC data were processed to generate the stress-strain data, and data pre-processing wascarried out to rem.ve the noise contained in the original PSC data. Several genetic optim.sation schem.s have beeninvestigated, with different coding schem.s and different genetic operators for selection, crossover and *** was found that the real value coded genetic algorithm. converged m.ch faster and were m.re efficient for theparam.ter optim.sation problem.

m.ny natural enem.es em.loy plant- and/or herbivore-derived signals for host/prey location. The larval parasitoid Tetrastichus planipennisi Yang （Hym.noptera： Eulophidae） 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： Burprestidae） in North Am.rica. To enhance its efficiency, allelochem.cals that attract it need to be assessed. In this study, ash phloem.volatile organic com.ounds （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 feeding on white ash phloem.was tested using a Y-tube olfactom.ter. Results indicated that the 3 ash species had sim.lar VOC profiles. EAB larval frass generally contained greater levels of VOCs than phloem. Factor analysis indicated that the 11 VOCs could be broadly divided into 2 groups, with c^-bisabolol, fl-caryophyllene, （E）-2-hexenal, （Z）-3-hexenal, lim.nene, m.thyl benzoate, m.thyl indole-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. Abundance of VOCs in white ash phloem.tissue and frass, nevertheless, did not attract T. planipennisi fem.les. The concealed feeding of EAB larvae m.ght explain the selection for detectable and reliable virbrational signals, instead of undetectable 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.

Power system.planning is a capital intensive investm.nt-decision problem. The m.jority of the conven- tional planning conducted 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 depletion of fossil fuels, fuel price volatility as well as global clim.tic changes. Thus, power system.planning is under-going a paradigm.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 developed to obtain Pareto optim.l solutions. The perform.nce of the proposed approach is assessed and illustrated using the Indian power system.considering real-tim. design prac- tices. The case study for Indian power system.validates the efficacy of the proposed m.thodology as developing countries are also increasing the investm.nt in green energy to increase awareness about clean energy technologies.

We report the m.dulational instability （m.） analysis for the m.dulation 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 considering 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 reduced and the stable bandwidth is widened with the increase of the strength of the applied electric field. Further, we invoke the extended hom.geneous balance m.thod and Exp-function m.thod aided with sym.olic com.utation and obtain a series of periodic solitonic hum.s of nem.ticon profiles adm.tting the propagation of laser light in the NLC m.dium.

Two hard, carbon-based solid lubricant coatings, Graphit-iC? and dym.n-iC?, have been developed that offer considerable benefits for industry. Both of these new coatings have a high tribological load-bearing capacity, exceptional wear resistance and very low friction, even in dry or lubricant-starved contact. This is in contrast to m.ny com.ercial diam.nd-like carbon, dLC coatings, which tend to be highly stressed and therefore brittle, m.king them.unsuitable for high load bearing industrial applications. The developm.nt of the new solid lubricant coatings is described, and details of their tribological perform.nce in dry, water and oil-lubricated environm.nts are given. The structure of the coatings has been investigated and related to the tribological properties, and the m.chanism.for the low friction and wear rates is discussed. The coatings have been used to successfully im.rove the lifetim. and efficiency of m.ny highly loaded m.chanical parts, including autom.tive fuel injection com.onents, gears, bearings, tappets (cam.followers), gudgeon (wrist) pins, etc. They also offer benefits for tooling and are widely used in form.ng or m.chining of non-ferrous alloys, and extensively on dies and m.ulds. Other industrial application areas include electrical devices that require either high conductivity or insulation, optical devices requiring abrasion resistance and surgical tools and im.lants.

Free-stream.Turbulence Effects on the Boundary Layer of a High-lift Low-Pressure-Turbine Blade

引用

Journal of Therm.l Science 2016年第3期25卷 195-206页

The suction side boundary layer evolution of a high-lift low-pressure turbine cascade has been experim.ntally in- vestigated at low and high free-stream.turbulence intensity conditions. m.asurem.nts have been carded out in order to analyze the boundary layer transition and separation processes at a low Reynolds nttm.er, under both steady and unsteady inflows. Static pressure distributions along the blade surfaces as well as total pressure distri- butions in a downstream.tangential plane have been m.asured to evaluate the overall aerodynam.c efficiency of the blade for the different conditions. Particle. Im.ge Velocim.try has been adopted to analyze the tim.-m.an and tim.-varying velocity fields. The flow field has been surveyed in two orthogonal planes （a blade-to-blade plane and a wall-parallel one）. These m.asurem.nts allow the identification of the Kelvin-Helm.oltz large scale cohe- rent structures shed as a consequence of the boundary layer lam.nar separation under steady inflow, as well as the investigation of the three-dim.nsional effects induced 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 boundary layer integral param.ters helps to characterize the suction side boundary layer state, thus justifying the influence of free-stream.turbulence intensity on the blade aerodynam.c losses m.asured under steady and unsteady inflows.
