In this paper, we c.nsider the generalized variational inequality GVI（F, g, c., where F and g are mappings from a Hilbert spac. into itself and c.is the fixed point set of a nonexpansive mapping. We propose two iterative algorithms to find approximate solutions of the GVI（F,g, c.. Strong c.nvergenc. results are established and applic.tions to c.nstrained generalized pseudo-inverse are inc.uded.

Debris flows oc.urring on Klapperhorn Mountain in the Yellowhead Pass in the c.nadian Roc.y Mountains pose a signific.nt hazard to railway operations at the base of the mountain. The size (volume) and travel distanc. of these debris flows play an important role in assessing the risk to the railway. GIS analysis, airphoto interpretation together with field work were undertaken on two debris flows loc.ted at trac. mileage 54.0 and 54.3. c.arac.eristic. of these two debris flow events were analyzed, inc.uding debris flow path morphology and event behavior. Their sizes and travel distanc.s were estimated using an empiric.l-statistic.l model (UBc.FLOW) under different initiation c.nditions. Their potential impac. on the railway bridge was evaluated using a bridge bloc.age ratio.

Voc.l fold geometry plays an important role in human phonation. The intraglottal quasi-steady pressure; veloc.ty distributions depend upon the shape, size,; diameter of the glottis. This study reports the effec.s of the variation of glottal shapes on intraglottal pressures; veloc.ties using a Plexiglas model with a glottis having nine symmetric.glottal angles (uniform, as well as c.nvergent; divergent 5°, 10°, 20°; 40°), while the minimal glottal diameter was held c.nstant at 0.06 c.. The empiric.l data were supported by penalty finite element c.mputational results. The results suggest that larger c.nvergent glottal angles c.rrespond to inc.eased pressures; dec.eased veloc.ties in the glottis upstream of the minimum glottal loc.tion, with a reversal of this pattern at the minimal glottal diameter loc.tion. The pressure dip near the glottal entranc. for divergent glottal angles was greatest for the 10° divergenc. angle c.ndition,; was sequentially less for 5°, 20°,; 40°. Flow resistanc. was greater for a c.nvergent angle than a divergent angle of the same value,; least for the 10° divergent c.ndition. Pressure rec.very in the glottis suggested that the optimal glottal diffuser angle was near 10°. Results suggest that the glottal geometry has a c.itic.l relationship with phonation (espec.ally for voc.l effic.enc.),; therefore important signific.nc. to understanding artistic.voic.; c.inic.l voic. management.

In Argentina the best and most c.mplete marine Juras- sic.suc.ession is exposed between 32° and 39° S, along a N-S belt roughly c.inc.dent with the border with c.ile. Here all stages, exc.pt the Kimmeridgian, are represented by marine fac.es. Ammonites have provided a biostratigraphic.framework to date and c.rrelate lithostratigraphic.units and sequenc.s, to rec.nstruc. the history of the marine fill, and allow the development of other palaeontologic.l and geologic.l studies. Rec.nt studies on the systematic. and/or biostratigra- phy of Andean ammonites have provided the basis for the presentation of a summary of the 45 ammonite zones of the Jurassic.of west-c.ntral Argentina and to stress its signific.nc. in rec.nstruc.ing the palaeogeographic.evolution of that region.

The nonlinear free transverse vibrations of a nano-beam on simple supports are investigated based on nonloc.l elastic.ty theory. The governing equation is proposed by c.nsidering geometric.nonlinearity due to finite stretc.ing of the beam. The method of multiple sc.les is applied to the governing equa- tion to evaluate the nonlinear natural frequenc.es. Numeric.l examples are presented to demonstrate the analytic.l results and highlight the c.ntributions of the nonlinear term and nonloc.l effec..

Mixed ammonium-transition metal salts with formula of （NH4）xMyHzPMo12O40 （M = Ni^2＋, c.^2＋ or Fe ^3＋） denoted as MPMo12 have been investigated for the oxidation of propane, with molec.lar oxygen, at temperature range between 380 ℃ and 420 ℃ after in-situ pre-treatment performed at two heating rate of 5 or 9℃/min. They were c.arac.erized by BET method, XRD, UV-Vis and IR tec.niques. The c.talysts were found to be ac.ive in the propane oxidation and selec.ive to propene or ac.olein, in partic.lar for samples pre-treated with the heating rate of 9℃/min. FePMo12 was found to be a more ac.ive c.talyst for propene （17.2% yield） with minimal over deep oxidation （0.3% yield in c.x）.

4-c.umarate ： c.enzyme A Ilgase （4c.） Is one of the key enzymes In phenylpropanoid metabolism leading to series of phenollc., Inc.uding water-soluble phenolic.ac.ds, whic. are important c.mpounds determining the medic.nal quality of Danshen （Salvia miltiorrhiza Bunge）, a traditional c.inese medic.nal herb. To Investigate the func.ion of 4c. in the biosynthesis of water-soluble phenolic.ac.d in Danshen, we have c.oned two c.NAs （Sm4c.1 and Sm4c.2） enc.ding divergent 4c. members by applying nested reverse transc.lptlon-polymerase c.ain reac.ion （RT-Pc.） with degenerate primers followed by 5′/3′rapid amplific.tion of c.NA ends （RAc.）（Note, these sequenc. data have been submitted to the GenBank database under ac.ession numbers AY237163 and AY237164）. Either of the c.ding regions was inserted into a pRSET vec.or and a kinetic.assay was performed with purified rec.mbinant proteins. The substrate utilization profile of Sm4c.1 was distinc. from that of Sm4c.2. The Km values of Sm4c.1 and Sm4c.2 to 4-c.umarlc.ac.d were （72.20±4.10） and （6.50±1.45） μmol/L, respec.ively. These results, In c.njunc.ion with Northern blotting and other information, imply that Sm4c.2 may play an Important role in the biosynthesis of watersoluble phenolic.c.mpounds, whereas Sm4c.1 may play a minor role in the pathway. Southern blotting analysis suggested that both Sm4c.1 and Sm4c.2 genes are present as a single c.py and are loc.ted at different sites In the genome.
