Long-grain rice cultivars Cocodrie, Wells, and XP 723 grown in th.ee locations （h.zen, MO; Essex and Newport, AR, USA）, and medium-grain rice cultivars Bengal and XP 713 grown in two locations （jonesboro and Lodge Corner, AR, USA）, were h.rvest.d and assayed for susceptibility to Rh.zoperth. dominica （F.）（Coleoptera： Bost.ich.dae）, th. lesser grain borer, and Sitoph.lus oryzae （L.）（Coleoptera： Curculionidae）, th. rice weevil, on rice h.ld at 27℃, 57% and 75% relative h.midity （Rh.. Separate samples from th. same h.rvest.lots were also analyzed for th. ph.sical ch.racterist.cs of brown rice yield, percentage wh.le kernels and kernel th.ckness. Progeny production and feeding damage of R. dominica were significantly different among long-grain cultivars with.n two of th. th.ee locations （P 〈 0.05）, but not for location or Rh.（P ≥ 0.05）, wh.le progeny production of S. oryzae was different among cultivars, location, and Rh.（P 〈 0.05）. On medium-grain rice, both.cultivar and location were significant for progeny production of R. dominica, but not Rh. wh.le cultivar and Rh.were significant for progeny production of S. oryzae, but not location. On both.rice types, feeding damage of R. dominica followed th. same trends and was always st.ongly positively correlated with.progeny production （P 〈 0.05）, but for S. oryzae th.re were several inst.nces in wh.ch.progeny production was not correlated with.feeding damage （P ≥ 0.05）. Ph.sical ch.racterist.cs of both.rice types were st.tist.cally significant （P 〈 0.01） but actual numerical differences were extremely small, and were generally not correlated with.progeny production of eith.r species. Results indicate th.t th. location in wh.ch.a particular rice cultivar is grown, along with.its ch.racterist.cs, could affect susceptibility of th. rice to R. dominica and S. oryzae.

Dynamics and mech.nisms of permeth.in resist.nce in a field population of th. h.rn fly, h.ematobia irritans irritans

Insect Science 2009年第2期16卷 175-184页

作者： Andrew Y. Li Kimberly h. Loh.eyer j. Allen Miller USDA ARS Knipling-Bushland US Livestock Insects Research Laboratory 2700 Fredericksburg Road Kerrville TX 78028 USA

A st.dy was conducted at th. Pressler ranch. near Kerrville, Texas, USA between 2002 and 2006 to determine th. dynamics and mech.nisms of resist.nce to permeth.in in a field population of th. h.rn fly, h.ematobia irritans irritans （L.）. Ch.nges of resist.nce to pyreth.oid insecticide associated with.use of a pour-on formulation of cyfluth.in in 2002 and use of diazinon ear tags in subsequent years were st.died using a filter paper bioassay tech.ique and a polymerase ch.in reaction assay th.t detects two sodium ch.nnel mutations, kdr and super-kdr resist.nce alleles. A maximum of 294-fold resist.nce to permeth.in was observed in th. summer of 2002. A significant decrease in th. resist.nce level was observed in spring 2003, and resist.nce continued to decline after animals were treated with.diazinon ear tags. In response to pyreth.oid treatments, th. allelic kdr and super-kdr frequency increased from 56.3% to 93.8% and from 7.5% to 43.8%, respectively in 2002, and decreased significantly in 2003 wh.n th. pyreth.oid insecticide was no longer used to treat animals. Females were found to h.ve a h.gh.r allelic super-kdr frequency th.n males in 2002, wh.le no difference was detected between males and females in th. allelic kdr frequency. Th.re was a significant positive correlation between frequencies of th. sodium ch.nnel mutations and levels ofpermeth.in resist.nce, suggest.ng th.t th. sodium ch.nnel mutations, kdr and super-kdr, are th. major mech.nisms of resist.nce to pyreth.oids in th.s h.rn fly population. Results of synergist.bioassays also indicated possible contributions of two metabolic detoxification mech.nisms, th. mixed function oxidases （MFO） and glutath.one S-trans- ferases （Gst.. Compared to a h.rn fly infest.tion of an untreated h.rd, treatments with.th. pyreth.oid pour-on formulation failed to control h.rn flies at th. Pressler ranch.in 2002. Sust.ined control of h.rn flies was ach.eved with.th. use of diazinon ear tags in 2003 and subsequent years.

Design and Mech.nics Simulation of Bionic Lubrication Syst.m of Artificial joints

journal of Bionic Engineering 2006年第3期3卷 155-160页

作者： S. h. Su Z. K. h.a j. h. Zh.ng Sch.ol of Mech.tronics Engineering and Automation Shanghai University Shanghai 200072 P R. China

We propose a new st.ucture for artificial joints with.a joint capsule wh.ch.is designed to overcome th. drawback of current prost.eses th.t omit many functions of th. lubricant and th. joint capsule. Th. new st.ucture is composed of th.ee components： lubricant, artificial joint and artificial joint capsule. Th. lubricant sealed in th. capsule can not only reduce th. wear of th. artificial joint but also prevents th. wear particles leaking into th. body. So unexpected reactions between th. wear particles and body can be avoided completely. A th.ee-dimensional （3-D） finite element analysis （FEA） model was created for a bionic knee joint with.capsule. Th. st.esses and th.ir dist.ibution in th. artificial capsule were simulated with.different th.ckness, loadings, and flexion angles. Th. results sh.w th.t th. maximum st.ess occurs in th. area between th. artificial joint and th. capsule. Th. effects of capsule th.ckness and th. angles of flexion on st.ess are discussed in detail.

Th. synth.sis of magnetic spinel ferrites at th. nanoscale is a field of intense st.dy, because th. meso- scopic properties enable th.ir novel applications. Spinel nanoparticles h.ve a promising role because of th.ir extraordinary properties compared with.th.se of micro and macro scale particles. Several colloidal ch.mical synth.tic procedures h.ve been developed to produce monodisperse nanoparticles of spinel let- rites and oth.r materials using sol-gel, co-precipitation, h.droth.rmal, and microemulsion tech.iques. To improve th. synth.sis meth.d and conditions, quality and productivity of th.se nanoparticles, underst.nding th. effect of extrinsic （ph. temperature, and molecular concentration） and intrinsic parameters （site preferences, latent h.at, lattice parameters, electronic configuration, and bonding energy） on th. particle size during synth.sis is crucial. In th.s review, we discuss th. effect of th. intrinsic parameters on particle size of spinel ferrites to provide an insigh. to control th.ir particle size more precisely.

We introduce th. Dirac equation in four-dimensional gravity wh.ch.is a generally covariant form. We ch.ose th. suitable variable and solve th. corresponding equation. To solve such.equation and to obtain th. corresponding bispinor, we employ th. factorization meth.d wh.ch.introduces th. associated Laguerre polynomial. Th. asso- ciated Laguerre polynomials h.lp us to write th. Dirac equation of four-dimensional gravity in th. form of th. sh.pe invariance equation. Th.s we write th. sh.pe invariance condition with.respect to th. secondary quantum number. Finally, we obtain th. spinor wave function and ach.eve th. corresponding st.bility of condition for th. four-dimensional gravity syst.m.

We consider an h. synch.onization problem in nonlinear Bloch.syst.ms. Based on Lyapunov st.bility th.ory and linear matrix inequality formulation, a dynamic feedback controller is designed to guarantee asymptotic st.bility of th. mast.r-slave synch.onization. Moreover, th.s controller reduces th. effect of an external dist.rbance to th. h. norm const.aint. A numerical example is given to validate th. proposed synch.onization sch.me.
