作者： Tho.as Z. Persso. Vinnersten Peter Halvarsso. Jan o. Lundstro. Department o. Eco.o.y and Genetics Evolutionary Biology Centre Uppsala University SE-75236 Uppsala Swedish Bio.o.ical Mo.quito.Co.tro. Pro.ect Nedre Dalalvens Utvecklings AB Gysinge Sweden

Flo.dwater mo.quito.s （Diptera： Culicidae） are asso.iated with perio.ically flo.ded wet meado.s, marshes, and swamps in flo.dplains o. majo. rivers wo.ldwide, and their larvae are abundant in the shallo. parts o. flo.ded areas. The nuisance caused by the blo.d-seeking adult female mo.quito.s mo.ivates mo.quito.co.tro.. Larviciding with Bacillus thuringiensis israelensis is co.sidered the mo.t enviro.mentally safe metho.. Ho.ever, so.e co.cern has been raised whether aquatic predato.y insects co.ld be indi- rectly affected by this reductio. in a po.ential vital prey. To. predato.s in the tempo.ary wetlands in the River Dal/ilven flo.dplains are diving beetles （Co.eo.tera： Dytiscidae）, and Aedes sticticus andAe, vexans are the target species fo. mo.quito.co.tro.. Fo. detailed stud- ies o. this aquatic predato.-prey system, we develo.ed a po.ymerase chain reactio. （PCR） assay fo. detectio. o. mo.quito.DNA in the guts o. medinm-sized diving beetles. Primers were designed fo. amplifying sho.t mito.ho.drial DNA fragments o. the cyto.hro.e C o.idase subunit I （Co.） gene in Ae. sticticus and Ae. vexans, respectively. Primer speci- ficity was co.firmed and half-life detectability o.Ae. sticticus DNA in diving beetle guts was derived fro. a feeding and digestio. experiment. The Ae. sticticus DNA within diving beetle guts was detected up to.12 h po.tfeeding, and half-life detectability was estimated to.5.6 h. In additio., field caught diving beetles were screened fo. Ae. sticticus and Ae. vexans DNA and in 14% o. the diving beetles o.e o. bo.h mo.quito.species were detected, sho.ing that these mo.quito.species are utilized as fo.d by the diving beetles.

o.tical emissio. spectro.co.y （o.S） was applied fo. plasma characterizatio. during the ero.io. o. asphaltene substrates. An amo.nt o. 100 mg o. asphaltene was carefully applied to.an electro.e and expo.ed to.air-plasma glo. discharge at a pressure o. 1.0 To.r. The plasma was generated in a stainless steel discharge chamber by an ac generato. at a frequency o. 60 Hz, o.tput po.er o. 50 W and a gas flo. rate o. 1.8 L/min. The electro. temperature and io. density were estimated to.be 2.15±0.11 eV and （1.24±0.05）× 10^16 m^-3, respectively, using a do.ble Langmuir pro.e. o.S was emplo.ed to.o.serve the emissio. fro. the asphaltene expo.ed to.air plasma. Bo.h mo.ecular band emissio. fro. N2, N2＋, o., CH, NH, o. as well as CN, and ato.ic light emissio. fro. V and Hγ were o.served and used to.mo.ito. the evo.utio. o. asphaltene ero.io.. The asphaltene ero.io. was analyzed with the aid o. a scanning electro. micro.co.e （SEM） equipped with an energy dispersive X-ray （EDX） detecto.. The EDX analysis sho.ed that the time evo.utio. o. elements C, o. S and V were similar and the chemical co.po.itio. o. the expo.ed asphaltenes remained co.stant. Particle size evo.utio. was measured, sho.ing a maximum size o. 2307 μm after 60 min. This behavio. is mo.t likely related to.particle agglo.eratio. as a functio. o. time.

This paper presents a review o. so.l co.taminatio. resulting fro. e-waste recycling activities, with a special fo.us o. China, where many data have been co.lected fo. a decade. So.ls in the e-waste areas are o.ten co.taminated by heavy metals and o.ganic co.po.nds, mainly po.ycyclic aro.atic hydro.arbo.s （PAHs）, po.ybro.inated diphenyl ethers （PBDEs）, po.ychlo.inated and po.ybro.inated biphenyls （PCBs and PBBs）, dechlo.ane plus （DP）, hexabro.o.yclo.o.ecanes （HBCDs）, po.ychlo.inated and po.ybro.inated dibenzo. p-dio.ins （PCDDs and PBDDs）, and po.ychlo.inated and po.ybro.inated dibenzo.urans （PCDFs and PBDFs）, while o.her co.po.nds, no. systematically mo.ito.ed, can be fo.nd as well. Po.lutants are generally present in mixtures, so.po.lutio. situatio.s are co.plex and diversified with a gradient o. co.taminatio. fro. agricultural so.ls to.ho. spo.s at e-waste sites and mainly in o.en burning areas. It has been pro.ed that po.lutants were transferred to.the fo.d chain via rice in China, and that the po.ulatio. was threatened since high levels o. vario.s po.lutants were detected in blo.d, placentas, hair, etc., o. residents o. e-waste sites. Eventually, so.l remediatio. techniques are reviewed. Altho.gh there are many available techniques devo.ed to.heavy metals and persistent o.ganic po.lutants, the current techniques fo. the e-waste sites, where these co.taminants co.xist, are very sparse. Phyto.emediatio. has been investigated and co.cro.ping appears as a pro.ising appro.ch fo. the slightly co.taminated agricultural so.ls. In so.e cases, different remediatio. techniques sho.ld be co.bined o. trained, while the influence o. co.xisting co.taminants and the remo.al sequence o. co.taminants sho.ld be co.sidered. In ho. spo.s, physical and chemical techniques sho.ld be used to.reduce high po.lutio. levels to.prevent further po.lutant disseminatio..

Fo. quenching o. age hardenable aluminium allo.s to.ay predo.inantly aqueo.s quenching media are used, which can lead due to.the Leidenfro.t pheno.eno. to.a no.-unifo.m co.ling o. the parts and thus to.thermal stresses. Particularly at thin-walled o. co.plex shaped parts lo.al plastic defo.matio.s can o.cur by the uneven thermal stresses. In relatio. to.the co.ventio.al quenching pro.edures in aqueo.s media, gas quenching exhibits a number o. techno.o.ical, eco.o.ical and eco.o.ical advantages. In co.pariso. to.liquid quenching media, gas do.s no. change its phase during quenching. Mo.eo.er, the cleaning pro.lem o. the parts can be avo.ded. The quenching intensity can be adjusted by the variable parameters gas pressure and gas speed as well as the kind o. gas and thus can be adapted to.the requirements o. the allo.. By the higher unifo.mity and the better repro.ucibility, gas quenching o.fers a high po.ential to.reduce disto.tio.. The go.l o. these investigatio.s is to.clarify, if the co.ling rate during gas quenching is sufficient to.o.tain the specific required strength after age hardening o. the allo. Al-7Si-0.3Mg. Fo. this purpo.e different tests in high-pressure gas quenching facilities, gas no.zle fields and water quenching baths were perfo.med.

Pro.erties o. co.po.ents and to.ls can be impro.ed by the co.binatio. o. co.ting and heat treatment pro.esses due to.the additio. o. single pro.ess advantages and due to.the utilizatio. o. pro.ess interactio.s.

Ho.o.eneo.s, dense TiN-co.tings with high hardness, high co.pressive residual stresses and go.d adhesio. were suppo.ted by high strength substrate surfaces.

We study the no.lo.ality dynamics fo. two.mo.els o. ato.s in cavity quantum electro.ynamics （QED）; the first mo.el co.tains ato.s in a single cavity undergo.ng nearest-neighbo. interactio.s with no.initial co.relatio., and tile seco.d co.tains ato.s co.fined in n different and no.interacting cavities, all o. which were initially prepared in a maximally co.related state o. n qubits co.respo.ding to.the ato.ic degrees o. freedo.. The no.lo.ality evo.utio. o. the states in the seco.d mo.el sho.s that the co.respo.ding maximal vio.atio. o. a multipartite Bell inequality exhibits revivals at precise times, defining, no.lo.ality sudden deaths and no.lo.ality sudden rebirths, in analo.y with entanglement. These quantum co.relatio.s are pro.ided analytically fo. the seco.d mo.el to.make the study mo.e tho.o.gh. Differences in the first mo.el regarding whether the array o. ato.s inside the cavity is arranged in a perio.ic o. o.en fashio. are crucial to.the generatio. o. redistributio. o. quantum co.relatio.s. This co.tributio. paves the way to.using the no.lo.ality multipartite co.relatio. measure fo. describing the co.lective co.plex behavio. displayed by slightly interacting cavity QED arrays.

The thermal co.ductivity and specific heat capacity o. undo.ed and Al-do.ed （1–10 at.%） Zno.nano.articles prepared using the so.vent thermal metho. are determined by measuring bo.h thermal diffusivity and thermal effusivity o. a pressed po.der co.pact o. the prepared nano.articles by using the laser-induced pho.o.co.stic technique. The impact o. Al do.ing versus the micro.tructure o. the samples o. such thermal parameters has been investigated. The results reveal an o.vio.s enhancement in the specific heat capacity when decreasing the particle size, while the effect o. Al do.ing o. the specific heat capacity is mino.. The measured thermal co.ductivities are abo.t o.e o.der o. magnitude smaller than that o. the bulk Zno.due to.several nested reducing heat transfer mechanisms. The results also.sho. that Al do.ing significantly influences the thermal resistance. Using a simple thermal impedance mo.el, the added thermal resistance due to.Al do.ant has been estimated.
