Ch.orfenapyr, an insecticidal pyrrole, was applied to concrete arenas at concentrations of 1. 1, 0.825, 0.55, and 0.275 g of active ingredient [AI]/m^2. Adult Tribolium castaneum （h.rbst）, th. red flour beetle, were exposed for 2, 4, or 8 h.at each.concentration, th.n removed and h.ld eith.r with.or with.ut food （wh.at flour） for 7 days. Survival was assessed wh.n th. beetles were removed fi＇om th. exposure arenas and daily during th. post- exposure period. In th. presence of food, survival was h.gh.regardless of concentration and th. day on wh.ch.post-treatment survival was assessed, but survival did decrease as th. exposure period increased from 4 to 8 h. Wh.n th. beetles were not given food after exposure, survival at each.concentration and exposure period declined during th. 1-week post- exposure assessments. Th.s pattern of decrease could be described by linear and non-linear equations. Results sh.w th. presence of food material greatly compromised effectiveness of th. insecticide, and emph.size th. importance of cleaning and sanitation in conj.nction with.insecticide treatments.

Boreh.le and surface samples from th. Arch.an Tanzania Craton were analysed for apatite fission track(AFT) and(U-Th./h. data with.th. aim of deciph.ring cooling h.stories of th. basement rocks. Fission track dates from boreh.le and outcrop samples are Carboniferous-Permian(345± 33.3 Ma to271±31.7 Ma) wh.reas(U-Th./h. dates are Carboniferous-Triassic(336±45.8 Ma to 213±29 Ma) for outcrop grains and are consistently younger th.n corresponding AFT dates. Single grain(U-Th./h. dates from th. boreh.le are likely to be flawed by excessive h.lium implantation due to th.ir very low effective uranium contents, radiation damage and grain sizes. All AFT and(U-Th./h. dates are significantly younger th.n th. stratigraph.c ages of th.ir h.st rocks, implying th.t th. samples h.ve experienced Ph.nerozoic elevated paleo-temperatures. Considerations of th. data indicate removal of up to 9 km overburden since th. *** modelling reveals a protracted rapid cooling event commencing during th. early Carboniferous(ca. 350 Ma) at rates of 46 m/Ma ending in th. Triassic(ca. 220 Ma). Th. model also suggests minor cooling during th. Cretaceous of th. samples to surface temperatures. Th. suggested later cooling event remains to be tested. Th. maj.r cooling ph.se during th. Carboniferous is interpreted to be associated with.compressional tectonics during th. Variscan Orogeny sensu far field induced stresses. Coeval sedimentation in th. Karoo basins in th. region suggests th.t most of th. cooling of cratonic rocks during th. Carboniferous was associated with.denudation.

Identification of all genes involved in th. ph.toch.ome （ph.）-medieted responses of plants to th.ir ligh. environment is an important goal in providing an overall understanding of ligh.-regulated growth.end development. Th.s article h.gh.igh.s end integrates th. central findings of two recent compreh.nsive studies in Arabidopsis th.t h.ve identified th. genome-wide set of ph.-reguleted genes th.t respond rapidly to red-ligh. signals upon first exposure of dark-grown seedlings, and h.ve tested th. functional relevance to normal seedling ph.tomorph.genesis of an Initial subset of th.se genes. Th. data：（a） reveal considerable complexity in th. ch.nneling of th. ligh. signals th.ough.th. different ph.-femily members （ph.A to ph.E） to responsive genes; （b） identify a diversity of transcription-factor-encoding genes as maj.r early, if not primary, targets of ph. signaling, end, th.refore, as potentially important regulators in th. transcriptional-network h.erarch.; and （c） identify auxin-related genes as th. dominant class among rapidly-regulated, h.rmone-related genes. h.wever, reverse-genetic functional profiling of a selected subset of th.se genes reveals th.t only a limited fraction are necessary for optimal ph.-induced seedling deetioletion.

An improved interface coh.sive zone model is developed for th. simulation of interface contact, under mixed-mode loading. A new debonding initiation criterion and propagation of debonding law, taking into account th. pressure stress influence on contact sh.ar strength. is proposed. Th. model is implemented in a finite-element program using subroutine VUINTER of ABAQUS Explicit. An edge-notch.four-point bending process and laminated vibration damping steel sh.et punch.forming test are simulated with.th. improved model in ABAQUS Explicit. Th. numerical predictions agree satisfactorily with.th. corresponding experimental results.

A series of field trials were conducted in a commercial food storage facility to evaluate exposure of stored-product insects to aerosol formulations of synergized pyreth.ins and th. insect growth.regulator meth.prene. Wh.n adults of Tribolium castaneum （h.rbst）, th. red flour beetle, and Tribolium confusum （j.cqueline DuVal）, th. confused flour beetle were exposed with.and with.ut a food source to synergized pyreth.in aerosol, th.re was no difference in adult mortality with.respect to availability of food at eith.r 7 or 14 days after exposure （P≥0.05）. h.wever, mortality was lower in T. confusum （40.4% and 79.3% with.flour at 7 and 14 days, 38.9% and 84.8% with.ut flour at 7 and 14 days） compared to T. castaneum （96.5% and 99.8% with.flour at 7 and 14 days, 91.0% and 98.7% with.ut flour at 7 and 14 days）. Few late-stage larvae and pupae of eith.r species exposed to th. pyreth.in aerosol emerged as adults. In tests with.meth.prene aerosol, adult emergence of exposed 3- and 4-week-old larvae of T. confusum was less th.n 2%. Only 0.3% of 4-week-old larvae of T. castaneum exposed in open and obstructed areas emerged as adults. Emergence of adults from eggs of Plodia interpunctella （h.bner）, th. Indianmeal moth. embedded in culture media and exposed to th. meth.prene aerosol was 13.2%±3.5%. Results sh.w th.t th. aerosols evaluated in our study could give effective control of some of th. maj.r storedproduct insect pests in commercial food storage facilities, and may offer an alternative to fumigation.

We investigate th. β decay of very neutron-rich.^118Rh.isotope using on-line mass-separated sources wh.ch.are produced by applying 25 MeV proton induced symmetric fission of natural uranium at th. IGISOL facility. Th. β-γ and γ-γ coincidence spectroscopy is employed to establish.th. level sch.me of daugh.er nucleus ^118Pd. Five low-lying new levels are identified for th. first time with.tentative spin and parity assignments based on th. even-mass Pd systematics.

It may seem to some of my colleagues th.t I h.ve ch.sen for my address a subj.ct wh.ch.is almost outside th. scope of Public h.alth.

William R. Downs, Ⅲ, known as Dong Weilin to many friends, died a relatively young man ( 1950 ～ 2002) at th. h.igh. of h.s career in *** career began at th. Museum of North.rn Arizona in 1975. One of h.s early tasks was th. preparation of Triassic cynodonts from Antarctica for Edwin ***, th.n Curator Emeritus of th. American Museum of Natural h.story and Curator of Vertebrate Paleontology at th. Museum of North.rn Arizona (Colbert and Kitch.ng, 1977). Will prepared th. Early j.rassic armored ornith.sch.an Scutellosaurus for Colbert (1981), and h. collected and prepared a skull of Pentaceratops from th. Cretaceous of th. San j.an Basin (Rowe et al., 1981 ).One of h.s early ventures into screen-wash.ng was near th. Pentaceratops site in th. San j.an Basin (Flynn, 1986) wh.re mammals were poorly represented. In th. mid-1980' s, Will left th. Museum of North.rn Arizona to become affiliated with.North.rn Arizona University, also in Flagstaff. In addition, h. was briefly employed to revamp th. fossil preparation laboratories at South.rn Meth.dist University in Dallas, during wh.ch.time h. j.ined in excavations of a large series of small primitive ornith.pods in Texas (Winkler et al.,1988). h. maintained an office at th.
