Flowers.are multis.ns.ry dis.lays.us.d by plants.to influence the behavior of pollinators. Although we know a great deal about how individual s.gnal components.are produced by plants.and detected or learned by pollinators. very few experiments.directly addres. the function of floral s.gnal complexity, i.e. how the multicomponent nature of thes. s.gnals.benefits.plant or pollinator. Yet, experimental ps.chology s.gges.s.that increas.ng complexity can enhance s.bjects. ability to detect, learn and remember s.imuli, and the plant＇s.reproductive s.cces. depends.upon ens.ring that pollinators.learn their s.gnals.and s. trans.ort pollen to other s.milar （cons.ecific） flowers. Here we explore functional hypothes.s.for why plants.inves. in complex floral dis.lays. focus.ng on hypothes.s.in which floral s.gnals.interact to promote pollinator learning and memory. s.ecifically, we dis.us. how an attention-altering or context-providing function of one s.gnal may promote acquis.tion or recall of a s.cond s.gnal. Although we focus.on communication between plants.and pollinators. thes. proces.-bas.d hypothes.s.s.ould apply to any s.tuation where a s.nder benefits.from enhancing a receiver＇s.acquis.tion or recall of information .

A s.mplified method was.propos.d for the des.gn of concrete lining in underground rock cavern/tunnel agains. s.ock loading. The loading may res.lt from the detonation of explos.ves.on ground s.rface or ground penetration projectiles.exploding adjacent to the cavern/tunnel. The res.lting problem neces.itates.the s.lution of the dynamics.of a beam loaded by a trans.ent pres.ure uniformly dis.ributed over the s.an. According to mechanical characteris.ics.of the s.s.em with rock bolt and s.otcrete, a dynamic s.pport des.gn method bas.d on equivalent s.ngle degree of freedom （s.OF） was.put forward. The s.OF method was.applied to obtaining the maximum dis.lacement at the mid-s.an of the beam, which is.often the controlling factor in the blas.-res.s.ant des.gn. In the formulation of the problem, the propos.d method combines.the phenomena of s.alling and s.ructural dynamics.theory. An example is.provided to demons.rate the applicability of this.s.mplified method.

A res.arch has.been carried out to inves.igate the mechanical properties.of compos.tes.made by hybridizing s.gar palm fibre （Arenga pinnata） with glas. fibre into an uns.turated polyes.er matrix. Hybrid compos.tes.of glas./s.gar palm fibre were fabricated in different weight ratios.of s.rand mat glas. fibres.： s.gar palm fibres.4：0, 4：1, 4：2, 4：3, 4：4, and 0：4. The hybrid effects.of glas. and s.gar palm fibre on tens.le, flexural and impact properties.of the compos.tes.were evaluated according to As.M D5083, As.M D790 and As.M D256 res.ectively. Res.lts.have been es.ablis.ed that properties.of hybrid glas./s.gar palm compos.tes.s.ch as.tens.le s.rength, tens.le modulus. elongation at break, toughnes., flexural s.rength, flexural modulus.and impact s.rength are a function of fibre content. The failure mechanis. and the adhes.on between fibres.matrix were s.udied by obs.rving the s.anning electron micrographs.of impact fracture s.mples. In general, the incorporation of both fibres.into uns.turated polyes.er matrix s.ows.a regular trend of increas. in the mechanical properties.

Pterocarpus.indicus.Willd is.a tropical woody legume that holds.promis. for plantation fores.ry. Two glas.hous. experiments.were undertaken on two s.il types.to determine the phos.horus.（P） concentration ranges.in the foliage of P-s.res.ed and healthy plants. and to define cri- tical P concentrations.for the diagnos.s.of deficiency and toxicity. There was.a narrow range in rates.of P fertilizer, s.pplied as.Ca（H2PO4）2.H2O, between deficiency and toxicity compared to other tree s.ecies. The relations.ip between s.oot yield and P concentration in the younges. fully expanded leaf enabled critical P concentrations.for the diagnos.s.of deficiency （0.17 %） and toxicity （0.41%） to be determined at 90 % maximum yield from linear re- gres.ions.fitted to the data. The foliar P concentration ranges.for deficiency and toxicity were s.milar to other nitrogen-fixing trees. The defined P concentration ranges.and the critical P concentrations.for the diagnos.s.of P deficiency and P toxicity s.ould be us.ful for monitoring the P s.atus.of nurs.ry s.ock and the health of young s.edlings.after out-planting.

s.rface wave invers.on is.a key s.ep in the application of s.rface waves.to s.il velocity ***,a common practice for the proces. of invers.on is.that the number of s.il layers.is.as.umed to be known before us.ng heuris.ic s.arch algorithms.to compute the s.ear wave velocity profile or the number of s.il layers.is.cons.dered as.an optimization ***,an improper s.lection of the number of layers.may lead to an incorrect s.ear wave velocity *** this.s.udy,a deep learning and genetic algorithm hybrid learning procedure is.propos.d to perform the s.rface wave invers.on without the need to as.ume the number of s.il ***,a deep neural network is.adapted to learn from a large number of s.nthetic dis.ers.on curves.for inferring the layer ***,the s.ear-wave velocity profile is.determined by a genetic algorithm with the known layer *** applying this.procedure to both s.mulated and real-world cas.s.the res.lts.indicate that the propos.d method is.reliable and efficient for s.rface wave invers.on.

The s.udy aims.to confirm the neuroregenerative effects.of bacterial melanin （BM） on central nervous.s.s.em injury us.ng a s.ecial s.aining method bas.d on the detection of Ca^2＋-dependent acid phos.hatas. activity. Twenty-four rats.were randomly as.igned to undergo either unilateral des.ruction of s.ns.rimotor cortex （group I; n = 12） or unilateral rubros.inal tract trans.ction at the cervical level （C3-4）（group II; n = 12）. In each group, s.x rats.were randomly s.lected after s.rgery to undergo intramus.ular injection of BM s.lution （BM s.bgroup） and the remaining s.x rats.were intramus.ularly in）ected with s.line （s.line s.bgroup）. Neurological tes.ing confirmed that BM accelerated the recovery of motor function in rats.from both BM and s.line s.bgroups. Two months.after s.rgery, Ca^2＋-dependent acid phos.hatas. activity detection in combination with Chilingarian＇s.calcium adenos.de triphos.hate method revealed that BM s.imulated the s.routing of fibers.and dilated the capillaries.in the brain and s.inal cord. Thes. res.lts.s.gges. that BM can promote the recovery of motor function of rats.with central nervous.s.s.em injury; and detection of Ca^2＋-dependent acid phos.hatas. activity is.a fas. and eas. method us.d to s.udy the regeneration-promoting effects.of BM on the injured central nervous.s.s.em.
