The abstrac.ion of c.mplex biologic.l lightweight struc.ure features into a prod.c.ble tec.nic.l c.mponent is a fund.- mental step within the transfer of d.sign princ.ples from nature to tec.nic.l lightweight solutions. A major obstac.e for the transfer of natural lightweight struc.ures to tec.nic.l solutions is their pec.liar geometry. Sinc. natural lightweight struc.ures possess irregularities and.often have extremely c.mplex forms d.e to elaborate growth proc.sses, it is usually nec.ssary to simplify their d.sign princ.ples. This step of simplific.tion/abstrac.ion has been used.in d.fferent biomimetic.method., but so far, it has an arbitrary c.mponent, i.e. it c.uc.ally d.pend. on the c.mpetenc. of the person who exec.tes the abstrac.ion. This paper d.sc.ibes a new method.for abstrac.ion and.spec.alization of natural mic.o struc.ures for tec.nic.l lightweight c.mpo- nents. The new method.generates stable lightweight d.sign princ.ples by using topology optimization within a d.sign spac. of preselec.ed.biologic.l arc.etypes suc. as d.atoms or rad.olarian. The resulting solutions are ad.pted.to the tec.nic.l load.c.ses and.prod.c.ion proc.sses, c.n be c.eated.in a large variety, and.may be further optimized.e.g. by using parametric.optimization.

The purpose of this paper is to present a c.mparison between the mod.fied.nonlinear Sc.rSd.nger （MNLS） equation and.the foc.sing and.d.foc.sing variants of the （unmod.fied. nonlinear Sc.rSd.nger （NLS） equation in the semic.assic.l limit. We d.sc.ibe aspec.s of the limiting d.namic. and.d.sc.ss how the nature of the d.namic. is evid.nt theoretic.lly through inverse-sc.ttering and.nonc.mmutative steepest d.sc.nt method.. The main message is that, d.pend.ng on initial d.ta, the MNLS equation c.n behave either lik. the d.foc.sing NLS equation, lik. the foc.sing NLS equation （in both c.ses the analogy is asymptotic.lly ac.urate in the semic.assic.l limit when the NLS equation is posed.with appropriately mod.fied.initial d.ta）, or lik. an interesting mixture of the two. In the latter c.se, we id.ntify a feature of the d.namic. analogous to a sonic.line in gas d.namic., a free bound.ry separating subsonic.flow from supersonic.flow.

Population growth, trophic.level, and.some aspec.s of reprod.c.ive biology of two c.ngeneric.arc.er fish spec.es, Toxotes c.atareus and.Toxotes jac.latrix, c.llec.ed.from Johor c.astal waters, Malaysia, were stud.ed. Growth pattern by length-weight relationship (W=aLb) for the sexes d.ffered. and.exhibited.positive allometric.growth (male, female and.c.mbined.sexes of T. c.atareus; female and.c.mbined.sexes of T. jac.latrix) and.isometric.growth (male samples of T. jac.latrix only). Trophic.levels of both spec.es were analyzed.based.on 128 spec.mens. The results show that, in both spec.es, c.ustac.ans and.insec.s were the most abund.nt prey items, and.among c.ustac.ans the red.c.awed.c.ab Sesarma bid.ns and.Formic.d.e family insec.s were the most represented.taxa. The estimated.mean trophic.levels for T. c.atareus and.T. jac.latrix were 3.422±0.009 and.3.420±0.020, respec.ively, ind.c.ting that they are largely c.rnivores. Fec.nd.ty of T. c.atareus ranged.from 38 354 to 147 185 eggs for females with total length ranging from 14.5 to 22.5 c. and.total bod. weight from 48.7 to 270.2 g, and.T. jac.latrix 25 251 to 150 456 eggs for females with total length ranging from 12.2 to 23.0 c. and.total bod. weight from 25.7 to 275.0 g. d.fferenc.s in values of gonad.somatic.and.hepatosomatic.ind.xes c.lc.lated.for both spec.es in this stud. may have resulted.from uneven sample size ranges.

Blink.ng is regard.d.as the c.ntinuous interrupted.eyelid.c.osure or opening and.its thermal effec. will c.mpromise between these two. d.ring a blink. the heat loss via c.nvec.ion, rad.ation and.tear evaporation from c.rnea is prevented. warm tear is lay- ered.ac.oss c.rneal surfac. and.the vessels of the palpebral c.njunc.iva provid. heat to anterior eye. In most of the thermal mod.ls in human eye that are found.in literatures, effec. of blink.ng is not inc.ud.d. simulation is c.rried.out only in open eye. Thus, in this paper, thermal effec.s of blink.ng are investigated.using one-d.mensional finite element method.in transient state c.se. The bio-heat transfer proc.ss is simulated.d.ring d.fferent blink.ng rates, lid.c.osure and.opening. The simulation is c.rried.out using normal and.extreme values of ambient temperatures, blood.temperatures, evaporation rates, blood.perfusion rates, and.lens thermal c.nd.etivities. Blink.ng is found.to inc.ease c.rneal and.lens temperature by 1.29℃ and.0.78℃ respec.ively when c.mpared.to open eye. The results obtained.from this mod.l are useful in pred.c.ing temperature d.stribution in d.fferent laser eye surgeries, hyperthermia and.c.yosurgery treatment of eyelid.c.rc.- noma, c.oroid.l melanoma and.c.n be used.for d.agnosing temperature-related.d.seases.
