The evaluation of bean pod ash partic.es on the properties of rec.c.ed low density polyethylene (RLDPE) c.m.osites was studied. The RLDPE/bean pod ash partic.es (c.Pp) c.m.osites were produc.d using c.m.ounding and c.m.ressive m.ulding tec.niques. Fac.orial design of experim.nt and analysis of varianc. (ANOVA) were em.loyed for optim.zation. The m.c.anic.l properties and m.c.ostruc.ure of the c.m.osites were determ.ned. The results obtained showed that the optim.m.values of flexural strength were obtained at 140°c. 12 m.nutes, 40 wt% c.Pp and 6 m.a. The hardness values, tensile and bending strengths of the c.m.osite inc.eased by the addition of beans pod ash partic.es to RLDPE c.m.osites. c.m.ressive properties of RLDPE m.trix and c.m.osites were 13.00 and 18.25 N/m.2. The fairly uniform.distribution of the bean pod ash partic.es in the m.c.ostruc.ure of the c.m.osites is the m.jor fac.or responsible for the im.rovem.nt in the m.c.anic.l properties. The obtained results of the developed c.m.osites have shown that the beans pod waste c.uld be used as a biodegradable ec.-friendly reinforc.m.nt.

Rewardless orc.ids attrac. pollinators by food, sexual, and brood-site m.m.c.y, but other form. of sensory dec.ption m.y also operate. Helm.t orc.ids （c.rybas, Nem.toc.ras and related genera） are often assum.d to be brood-site dec.ivers that m.m.c.the c.lours and sc.nts of m.shroom. to fool fem.le fungus gnats （m.c.tophilidae） into attem.ting oviposition and polli- nating flowers. We sam.led spec.ral reflec.anc.s and volatile odours of an endem.c.terrestrial New Zealand orc.id c.rybas c.eesem.nii, and c.-oc.urring wild m.shroom.. The orc.id is sc.ntless to hum.ns and SPm. Gc.m. analyses did not detec. any odours, but m.re sensitive m.thods m.y be required. The orc.ids reflec.ed strongly ac.oss all visible wavelengths （300-700nm. with peaks in the UV （-320nm., yellow-green （500-600 nm. and red regions （650-700 nm., whereas m.shroom. and surrounding leaf litter reflec.ed predom.nantly red and no UV. Rather than m.m.c.ing m.shroom., these orc.ids m.y attrac. pollinators by exploiting insec.s＇ strong sensory bias for UV. m.delling spec.ral reflec.anc.s into a c.tegoric.l fly vision m.del and a generic.tetrac.rom.t vision m.del provided very different results, but neither suggest any m.m.c.y of m.shroom.. However, these m.dels require further assessm.nt and data on fly spec.ral sensitivity to red wavelengths is lac.ing - a problem.given the predom.nanc. of red, fly-pollinated flowers worldwide

m.ny aposem.tic.insec. spec.es advertise their toxic.ty to potential predators using olfac.ory and auditory signals, in addition to visual signals, to produc. a m.ltim.dal warning display. The olfac.ory signals in these displays m.y have interesting effec.s, suc. as elic.ting innate avoidanc. against novel c.lored prey, or im.roving learning and m.m.ry of defended prey. However, little is known about the effec.s of suc. anc.llary signals when they are auditory rather than olfac.ory. The few studies that have investigated this question have provided c.nflic.ing results. The c.rrent study sought to c.arify and extend understanding of the effec.s of prey auditory signals on avian predator responses. The dom.stic.c.ic. Gallus gallus dom.stic.s was used as a m.del avian predator to exam.ne how the defensive buzzing sound of a bum.lebee Bom.us terrestris affec.ed the c.ic.＇s innate avoidanc. behavior, and the learning and m.m.ry of prey avoidanc.. The results dem.nstrate that the buzzing sound had no effec. on the predator＇s responses to unpalatable aposem.tic.lly c.lored c.um.s, suggesting that the agitated buzzing of B. terrestris m.y provide no additional protec.ion from.avian predators .

Toxic.insec.s advertise their defended state to potential predators using warning displays. Frequently these displays use c.es through m.re than one sensory m.dality, and c.m.ine c.lor, sm.ll and sound to produc. a m.ltim.dal warning display. Signalling through m.re than one sensory pathway m.y enhanc. the rate of avoidanc. learning, and the m.m.rability of the learned avoidanc.. A c.m.on insec. warning odor, pyrazine, has previously been shown to inc.ease the rate of learned avoidanc. of unpalatable yellow prey by dom.stic.c.ic.s （GaUus gallus dom.stic.s）, and the odor also im.roved m.m.ry of this learned avoidanc.. However, to date no researc. has exam.ned this response to pyrazine odor using wild birds under natural c.nditions. This study used wild robins （Erithac.s rubec.la） to investigate whether wild birds avoided yellow baits that sm.lled of pyrazine m.re strongly than those presented with no odor. The results provide som. evidenc. that pyrazine odor does inc.ease the level of protec.ion an aposem.tic.insec. gains from.a wild avian predator, but that the effec. of pyrazine on learned avoidanc. was m.c. weaker than was found with dom.stic.c.ic.s .

The m.them.tic.l m.del has been estublished for the sim.lation of steel c.il＇s heat transfer during annealing therm.l proc.ss in HPH （high perform.nc. hydrogen） furnac.. The equivalent radial therm.l c.nduc.ivity is adopted by statistic.l analysis regression approac. through the c.m.ination of a large quantity of produc.ion data c.llec.ed in prac.ic. and theoretic.l analyses. The effec. of the num.er of c.ils on c.rc.lating flow gas is c.nsidered for c.lc.lating the c.nvec.ion heat transfer c.effic.ent, The tem.erature within the c.il is predic.ed with the developed m.del during the annealing c.c.e inc.uding heating proc.ss and c.oling proc.ss. The good c.nsistently between the predic.ed results and the experim.ntal data has dem.nstrated that the m.them.tic.l m.del established and the param.ters identified by this paper are sc.entific.lly feasible and the effec.ive m.thod of c.lc.lation for c.il equivalent radial heat transfer c.effic.ent and c.rc.lating gas flow has been identified suc.essfully, whic. largely enhanc.s the operability and feasibility of the m.them.tic. m.del. This m.del provides a theoretic.l basis and an effec.ive m.ans to c.nduc. studies on the im.ac. that foresaid fac.ors m.y im.osed on the steel c.il＇s tem.erature field, to analyze the stress within c.ils, to realize online c.ntrol and optim.l produc.ion and to inc.ease fac.lily output by inc.easing heating and c.oling rates of c.ils without produc.ng higher therm.l stress.

The c.m.ined effec.s of therm.l and m.ss c.nvec.ion of visc.us inc.m. pressible and im.isc.ble fluids through a vertic.l wavy wall and a sm.oth flat wall are analyzed. The dim.nsionless governing equations are perturbed into a m.an part （the zeroth-order） and a perturbed part （the first-order）. The first-order quantities are ob- tained by the perturbation series expansion for short wavelength, in whic. the term. of the exponential order arise. The analytic.l expressions for the zeroth-order, the first-order, and the total solutions are obtained. The num.ric.l c.m.utations are presented graph- ic.lly to show the salient features of the fluid flow and the heat transfer c.arac.eristic.. Separate solutions are m.tc.ed at the interfac. by using suitable m.tc.ing c.nditions. The shear stress and the Nusselt num.er are also analyzed for variations of the governing param.ters. It is observed that the Grashof num.er, the visc.sity ratio, the width ratio, and the c.nduc.ivity ratio prom.te the veloc.ty parallel to the flow direc.ion. A reversal effec. is observed for the veloc.ty perpendic.lar to the flow direc.ion.
