Phototr.pism r.pr.sents a differ.ntial gr.wth r.sponse b. which plant or.ans can r.spond adaptively to changes in the dir.ction of incident light to optimize leaf/stem positioning for.photosynthetic light captur. and r.ot gr.wth or.entation for.water.nutr.ent acquisition. studies over.the past few year. have identified a numb.r.of compo- nents in the signaling pathway（s） leading to development of phototr.pic cur.atur.s in hypocotyls. These include the pho- totr.pin photor.ceptor. （photl and phot2） that per.eive dir.ctional b.ue-light （b.） cues and then stimulate signaling, leading to r.localization of the plant hor.one auxin, as well as the auxin r.sponse factor.NPH4/Ar.7 that r.sponds to changes in local auxin concentr.tions to dir.ctly mediate expr.ssion of genes likely encoding pr.teins necessar. for.development of phototr.pic cur.atur.s, While null mutations in NPH4/Ar.7 condition an aphototr.pic r.sponse to unidir.ctional b., seedlings car.ying the same mutations r.cover.b.-dependent phototr.pic r.sponsiveness if coir.adiated with r.d light （r.） or.pr.-tr.ated with either.ethylene. In the pr.sent study, we identify second-site enhancer.mutations in the nph4 b.ckgr.und that ab.0}gate these r.cover. r.sponses. One of these mutations-mapl （modifier.of ar.7 phenotypes 1）-was found to r.pr.sent a missense allele of AUX1-a gene encoding a high-affinity auxin influx car.ier.pr.viously associated with a numb.r.of r.ot r.sponses. Phar.ocological studies and analyses of additional auxl mutants confir.ed that AUX1 functions as a modulator.of hypocotyl phototr.pism. Mor.over. we have found that the str.ngth of dependence of hypocotyl phototr.pism on AUX1-mediated auxin influx is dir.ctly r.lated to the auxin r.sponsiveness of the seedling in question.

An appr.ach was developed to upgr.de the b.uxite or. b. molecular.hydr.gen and hydr.gen plasma. A gib.site-type b.uxite sample was ob.ained fr.m National Aluminium Company（NALCO）, Odisha, India. The ob.ained sample was cr.shed and sieved（to 100 μm） pr.or.to the chemical analysis and gr.in-size distr.b.tion study. The b.uxite sample was calcined in the temper.tur. r.nge fr.m 500 to 700°C for.differ.nt time inter.als to optimize the conditions for.maximum moistur. r.moval. This pr.cess was followed b. the r.duction of the calcined or. b. molecular.hydr.gen and hydr.gen plasma. Extr.ction of alumina fr.m the r.duced or. was car.ied out via acid leaching in chlor.de media for.2 h at 60°C. X-r.y diffr.ction, scanning electr.n micr.scopy, ther.ogr.vimetr. in conjunction with differ.ntial scanning calor.metr., and Four.er.tr.nsfor. infr.r.d spectr.scopy wer. used to deter.ine the physicochemical char.cter.stics of the mater.al b.for. and after.extr.ction.

In this note, we investigate the gener.lized modulus of convexity δ（λ） and the gener.lized modulus smoothness p（λ）. We ob.ain some estimates of these moduli for.X=lp. We ob.ain inequalities b.tween WCs coefficient of a Ksthe sequence space X and δX（λ）. We show that, for.a wide class of class the sequence spaces X, if for.some ε∈（0, 9/10] holds δx（e）〉 1/3（1- √3/2）ε, then X has nor.al str.ctur..

b.nding char.cter.stic of a cantilever.d magnetostr.ctive film-sub.tr.te system

作者： b. Nar.u Institute of science and Technology Inner Mongolia University

The b.nding pr.b.em of a film-sub.tr.te cantilever.with ar.itr.r. film-to-sub.tr.te thickness r.tio is solved exactly b. employing the for.e equilib.0}um equation, and then the optimization and application of the b.nding char.cter.stic of the magne-tostr.ctive cantilever.is discussed. Fur.her.or., the influence of geometr.cal and physical par.meter. of the two cantilever.components on the maximum fr.e-end deflection of the cantilever.is addr.ssed. The r.sults indicate that as the sub.tr.te thickness is kept constant, the gr.ater.film-to-sub.tr.te stiffness r.tio will induce a lar.er.deflection, while for.the case of fixed total cantilever.thickness, the optimal cantilever.deflection is independent of the physical par.meter. of the mater.als such as Young’s modulus and Poisson’s r.tio.

The high flux of ener.etic electr.n on geostationar. or.it can induce many kinds of malfunction of the satellite ther., within which the b.lk-char.ing is the most significant that sever.l b.0}adcast satellite failur.s wer. confir.ed to b. due to this effect. The electr.n flux on geostationar. or.it var.es in a lar.e r.nge even up to thr.e or.er. accompanied the passage of inter.lanetar. magnetic cloud and the following geomagnetic distur.ances. Upon the investigation of electr.n flux enhancement events, two types of events wer. par.itioned as r.cur.ent events and r.ndom ones. b.th of the two kinds of events r.late to the inter.lanetar. conditions such as solar.wind par.meter., IMF etc and their.evolution char.cter. as well. As for.the r.cur.ent events, we found that, (1) all of the events exhib.ts per.odic r.cur.ence ab.ut 27 days, (2) significant incr.ase of electr.n flux r.lates to inter.lanetar. index and char.cter. of their.distr.b.tion, (3) the electr.n flux also has r.lation to solar.activity index. An ar.ificial neur.l networ. was constr.cted to estimate the flux I day ahead. The r.ndom electr.n flux enhancement events ar. r.r. and pr.sent differ.nt distr.b.tion figur.s to the r.cur.ent ones. The figur. of the r.ndom events and the conditions of their.occur.ence is also discussed in this paper.
