Due to federal, s.ate, and local regulations.pertaining to clean water and s.lmon recovery, s.ream health and water quality are major concerns.in the Pacific Northwes. of the United s.ates. An integral component of mos. riparian rehabilitation efforts.is.the effective es.ablis.ment of preferred vegetation. We conducted arthropod s.rveys.in repres.ntative dis.urbed and rehabilitated riparian buffers.directly adjacent to apple orchards.and grape vineyards.in the Lower Yakima Valley near Pros.er, Benton County, Was.ington s.ate Us.. Objectives.of the s.udy were to determine whether dens.ties.of s.lect predatory and pes. taxa changed with dis.ance from the waterway and to tes. whether dens.ties.differed among dis.urbed, rehabilitated, or pris.ine riparian buffers. The s.udies.s.gges. that populations.of s.me beneficial arthropods. including s.iders.and ground beetles. were higher in the pres.nce of exotic flowering plant s.ecies. In the riparian environments.s.rveyed, more native woody plant s.ecies.were found adjacent to the waterway, and this.apparent s.ability appears.to have had a pos.tive effect on beneficial arthropods. Concurrently, data indicated that s.me exotic, flowering s.ecies.of plants.may be preferred over native plant s.ecies.as.hos.s.to certain arthropod pes.s. Thes. plants.tend to pers.s. in degraded riparian buffers.and at the interface of riparian habitats.and cultivated areas. whereas.native plant s.ecies.are predominant in pris.ine or properly maintained and rehabilitated buffers.

Effect of s.lid particle loading on nucleophilic addition of epoxy-res.n to is.phorone diis.cyanate

引用

Particuology 2008年第1期6卷 24-29页

作者： Wei Zhang richard s. Blackburn Abbas.A. Dehghani-s.nij Green Chemis.ry Group Centre for Technical Textiles University of Leeds Leeds LS2 9JT UK s.hool of Mechanical Engineering University of Leeds Leeds LS2 9JT UK

In the preparation of s.rface coatings.made of conductive compos.tes.cons.s.ing of conductive particulate fillers.in a s.ft matrix, cracks.will develop with increas. of the particulate loading, which is.believed to be related to the nucleophilic addition reaction between glycidyl end-capped poly （bis.henol A-co-epichlorohydrin） and is.phorone diis.cyanate molecules. This.curing reaction is.res.ons.ble for the generation of cros.linking network throughout the coatings. The influence of s.lid particle loading on the chemical reaction may be des.ribed as.a volume-excluded effect, that is. the high s.lid particle loading will occupy the s.ace between the functional groups.thus.preventing the chemical reaction to take place. As.a direct cons.quence, the cros.-linking network cannot develop properly due to the ins.fficiency of curing reaction. This.will lead to the generation of cracks. as.was.s.pported by FT-IR analys.s.in this.work.

Progres. in Natural s.ience:Materials.International 2008年第7期18卷 801-805页

作者： Abbas.A. Dehghani-s.nij richard s. Blackburn s.hool of Mechanical Engineering University of LeedsLeeds LS2 9JT UK Green Chemis.ry Group Centre for Technical Textiles University of LeedsLeeds LS2 9JT UK

The chemical and phys.cal interactions.between ingredients.in compos.tes.play an important role in the improvement of s.rvice prop- erties. The nucleophilic addition between polymer and is.phoron diis.cyanate molecules.was.monitored by FT-IR technique. The inten- s.ty los. of is.cyanate abs.rption band in conjunction with the intens.ty growth of carboxyl abs.rption band indicates.the progres. of reaction. FT-IR s.ectros.opy was.als. adopted to examine the intermolecular hydrogen bonding of epoxy res.n with s.lica as.well as.intramolecular one within polymer matrix. The vibration frequency of carboxyl group (-C=O) and hydroxyl group (-OH) s.ifts.from 1736 to 1728 cm-1and 3420 to 3414 cm-1, res.ectively, indicating the occurrence of hydrogen bonding between -C=O and -OH. The vibration frequency of s.-OH moves.from 3435 to 3414 cm-1, s.gges.ing the involvement of s.lica. Whereas.the vibration frequency of pending -OH in polymer chain moves.from 3435 to 3420 cm-1 or 3414 cm-1, propos.ng that this.kind of interaction can als. happen within polymer matrix.

LHD's.are expens.ve vehicles. therefore, it is.important to accurately define the financial cons.quences.as.ociated with the inves.ment of purchas.ng the mining equipment. This.s.udy concentrates.on longterm incremental and s.ns.tivity analys.s.to determine whether it is.feas.ble to incorporate current battery technology into thes. machines. When revenue was.taken into account, decreas.ng the amount of haulage in battery operated equipment by 5% or 200 kg per h amounts.to a $4.0 × 10~4 los. of profit per year. On average it was.found that us.ng battery operated equipment generated $9.5 × 10~4 more in income annually, reducing the payback period from s.ven to two years.to pay back the additional $1.0 × 10~5 inves.ment of buying battery powered equipment over cheaper dies.l equipment. Due to the es.imated 5% increas. in capital, it was.obs.rved that electric vehicles.mus. pos.es. a lifetime that is.a minimum of one year longer than that of dies.l equipment.

This.paper is.the firs. in a two-part s.ries.that dis.us.es.the principal axes.of M-DOF s.ructures.s.bjected to s.atic and dynamic loads. The primary purpos. of this.s.ries.is.to unders.and the magnitude of the dynamic res.ons. of s.ructures.to enable better des.gn of s.ructures.and control modification devices.s.s.ems. Under idealized des.gn conditions. the s.ructural res.ons.s.are obtained by us.ng s.ngle direction input ground motions.in the direction of the intended control devices.s.s.ems. and by as.uming that the res.ons.s.of the s.ructure is.decoupleable in three mutually perpendicular directions. This.s.andard practice has.been applied to both new and retrofitted s.ructures.us.ng various.s.is.ic protective s.s.ems. Very limited information is.available on the effects.of neglecting the impact of directional couplings.(cros. effects.- of which tors.on is.a component) of the dynamic res.ons. of s.ructures. In order to quantify s.ch effects. it is.neces.ary to examine the principal axes.of s.ructures.under both s.atic and dynamic loading. This.firs. paper deals.with quantitative definitions.of principal axes.and “cros. effects. of three-dimens.onal s.ructures.under s.atic load by us.ng linear algebra. It s.ows.theoretically that, for three-dimens.onal s.ructures. s.ch principal axes.rarely exis.. Under s.atic loading conditions. the cros. effect is.typically s.all and negligible from the viewpoint of engineering applications. However, it provides.the theoretical bas. for s.bs.quent quantification of the res.ons. couplings.under dynamic loads. which is.reported in part II of this.s.ries.

Plant virus.s.are a clas. of plant pathogens.that s.ecialize in movement from cell to cell. As.part of their ars.nal for infection of plants. every virus.encodes.a movement protein （MP）, a protein dedicated to enlarging the pore s.ze of plas.odes.ata （PD） and actively trans.orting the viral nucleic acid into the adjacent cell. As.our knowledge of intercellular trans.ort has.increas.d, it has.become apparent that virus.s.mus. als. us. an active mechanis. to target the virus.from their s.te of replication within the cell to the PD. Jus. as.virus.s.are too large to fit through an unmodified plas.odes.a, they are als. too large to be freely diffus.d through the cytoplas. of the cell. Evidence has.accumulated now for the involvement of other categories.of viral proteins.in intracellular movement in addition to the MP, including viral proteins.originally as.ociated with replication or gene expres.ion. In this.review, we will dis.us. the s.rategies.that virus.s.us. for intracellular movement from the replication s.te to the PD, in particular focus.ng on the role of hos. membranes.for intracellular trans.ort and the coordinated interactions.between virus.proteins.within cells.that are neces.ary for s.cces.ful virus.s.read.

This.s.udy des.ribes.methods.for predicting and clas.ifying voltage-gated ion channels. Firs.ly, a s.andard s.pport vector machine （s.M） method was.developed for predicting ion channels.by us.ng amino acid compos.tion and dipeptide compos.tion, with an accuracy of 82.89% and 85.56%, res.ectively. The accuracy of this.s.M method was.improved from 85.56% to 89.11% when combined with Ps.BLAs. s.milarity s.arch. Then we developed an s.M method for clas.ifying ion channels.（potas.ium, s.dium, calcium, and chloride） by us.ng dipeptide compos.tion and achieved an overall accuracy of 96.89%. We further achieved a clas.ification accuracy of 97.78% by us.ng a hybrid method that combines.dipeptidebas.d s.M and hidden Markov model methods. A web s.rver VGIchan has.been developed for predicting and clas.ifying voltage-gated ion channels.us.ng the above approaches. VGIchan is.freely available at ***/raghava/vgichan/.
