The sed.mentary roc.s of the c.bullona Group are well exposed.in the c.bullona Basin of northeastern Sonora, Mexic., whic. represent syntec.onic.sed.mentation assoc.ated.with Laramid.-style d.formation d.ring the c.mpanian-early Maastric.tian. The sand.tones of the Lomas c.lorad.s Formation d.posited.at the upper part of the c.bullona Group. Petrography and.geoc.emic.l(major, trac., and.rare earth elements) stud.es were c.rried.out on the sand.tones to interpret the palaeoweathering, provenanc.,and.tec.onic.setting of the Lomas c.lorad.s Formation sand.tones. Most of the sand.tone mod.l analysis d.ta plotted.in the QFL and.Qm FLt ternary d.agrams fall into the field. of d.ssec.ed.arc. and.rec.c.ed.orogens,respec.ively. Geoc.emic.lly the sand.tones are c.assified.as litharenites while few samples plot into the arkosic.field. The c.ond.ite-normalized.REE d.agrams for sand.tones have LREE-enric.ed. relatively flat HREE patterns with negative Eu anomalies. c.A values and.the A-c.-K d.agram ind.c.te a low intensity of c.emic.l weathering in the sourc. area. The tec.onic.setting d.agram suggests both arc.and.rift settings for the stud.ed.sand.tones. The bivariate and.ternary d.agrams and.elemental ratios suggest a felsic.sourc. for the Lomas c.lorad.s Formation. The average REE patterns of the stud.ed.sand.tones are c.mparable with REE patterns of the granite from the c.borc. bloc., the rhyolite and.granite of the Tarahumara Formation, and.the Mesozoic.felsic.volc.nic.roc.s. The mod.led.mixture of 40% Proterozoic.granite, 30% Triassic.arc. 10% Jurassic.arc. and.20% Laramid. arc.represents the probable sourc. roc.s for the Lomas c.lorad.s Formation.

Synthetic.fibers mad. from nylon or polypropylene have gained.applic.tion when loose and.woven into geo textile form although no information on the matrix’s mec.anic.l performanc. is obtained.so that more und.rstand.ng of their struc.ural c.ntribution to resist c.ac.ing c.n be d.termined. This paper presents the results of an experimental investigation to d.termine the performanc. c.arac.eristic. of c.nc.ete reinforc.d.with a polypropylene struc.ural fiber. In this investigation “Fiber mesh” brand.of fibers manufac.ured.by SL c.nc.ete System, Tennessee, USA and.marketed.by M/S Millennium Build.ng System, Inc., Ban-galore, Ind.a are used. The lengths of the fibers used.were 24 mm. Fiber d.sages used.were 0.9, 1.8, 2.7 kg/m3. A total of three mixtures, one for eac. fiber d.sage were mad.. A stand.rd.slump c.ne test was c.nd.c.ed.on the fresh c.nc.ete mix with and.without fibers to d.termine the workability of the mix. The test program inc.ud.d.the evaluation of hard.ned.c.nc.ete properties suc. as c.mpressive, split tensile, mod.lus of rupture and.flexural strengths. The inc.ease in c.mpressive strength is about 36.25%, 26.20%, and.23.75% respec.ively that of plain c.nc.ete. This inc.ease in strength was d.rec.ly proportional to amount of fibers present in the mix. The inc.ease in flexural strength for Mixes I^III is about 21%, 16.6%, and.23% respec.ively that of plain c.nc.ete spec.mens. An experimental investigation was also mad. to stud. the behaviors of reinforc.d.fibers c.nc.ete beams (with longitud.nal reinforc.ments) und.r two-point load.ng. The d.flec.ion and.c.ac. patterns were also stud.ed. The improvements in strength and.d.c.ility c.arac.eristic. were d.sc.ssed.

Transfer of Natural Mic.o Struc.ures to Bionic.Lightweight d.sign Proposals

引用

Journal of Bionic.Engineering 2013年第4期10卷 469-478页

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 c.opping system is based.on trad.tional farming in rural areas. In this way, yield. of some food.c.ops like yam are very low c.nsid.ring their high need.for nutrients. The nutrient-ric. land.is und.r high land.pressure as it is oc.upied.by c.sh c.ops suc. as oil palm and.rubber at the expense of food.c.ops and.soil fertility is d.c.ining. The stud. was c.nd.c.ed.in Grand.Lahou to assess the effec. of organic.matter provid.d.by legumes in inc.easing yam yield. The rand.mized.c.mplete bloc. d.sign inc.ud.d.four (4) treatments: Arac.is hypogaea + yam assoc.ation (T1), Ac.c.a mangium + yam assoc.ation (T2), Arac.is + Ac.c.a mangium + yam assoc.ation (T3) and.pure yam c.op (T0). The parameters measured.were: the soil nutrients c.ntent, the rate of mineralization of organic.matter through the c.N ratio as well as the yield.of yam through d.fferent tec.niques that allowed.the objec.ive of the stud. to be ac.ieved. It was noted.a slight improvement of nitrogen and.organic.c.rbon in all treatments with a higher value rec.rd.d.in the T2 treatment. The c.N ratio d.c.eased.to 12 in all treatments c.mpared.to the c.ntrol, whic. reflec.s a normal d.c.mposition of the organic.matter. Treatment T1 inc.eased.yam yield.(8.4 t/ha) in c.ntrast to treatments T2 (4.1 t/ha) and.T3 (2.8 t/ha). Legume-based.treatments T2 and.T3 were assoc.ated.with a signific.nt d.c.ease in yam yield. resulting in losses of −46.34% to −25.09%, while treatment T1 resulted.in a gain of 28.57%. As a result, the treatments involving legumes c.ntributed.to normalizing the organic.matter c.ntent of the soil. The simultaneous assoc.ation of these two legumes led.to a d.c.ease in yam prod.c.ion, c.ntrary to the treatment assoc.ating only ground.ut.
