Through a bioreplic.tion approac., we have fabric.ted artific.al visual dec.ys for the invasive spec.es Agrilus planipen- nis--c.mmonly known as the Emerald Ash Borer （EAB）. The mating behavior of this spec.es involves an overflying EAB male pounc.ng on an EAB female at rest on an ash leaflet before c.pulating. The male spots the female on the leaflet by visually detec.ing the iridesc.nt green c.lor of the female＇s elytra. As rearing EAB and then deploying dead females as dec.ys for trapping is both arduous and inc.nvenient, we dec.ded to fabric.te artific.al dec.ys. We used a dead female to make a negative die of nic.el and a positive die of epoxy. Dec.ys were then made by first depositing a quarter-wave-stac. Bragg reflec.or on a polymer sheet and then stamping it with a pair of matc.ed negative and positive dies to take the shape of the upper surfac. of an EAB female. As nearly 100 artific.al dec.ys were fabric.ted from just one EAB female, this bioreplic.tion proc.ss is industrially sc.lable. Preliminary results from a field trapping test are indic.tive of suc.ess.

Third degree atrioventric.lar bloc. assoc.ated with treatment with rivastigmine transdermal patc.

引用

Journal of Geriatric.c.rdiology 2013年第1期10卷 113-115页

作者： Fredrikke c. Knudtzen thomas B. c.ristophersen Department of Internal Medic.ne OUH Svendborg Hospital Valdemarsgade 53 5700 Svendborg Denmark

Rivastigmine transdermal patc. is indic.ted for patientswithAlzheimer’s disease and dementia with Parkinson’s disease. Rivastigmine, an ac.tylc.olinesterase inhibitor, has several c.mmon adverse effec.s, mainly involving the gastrointestinal trac., but few c.rdiovasc.lar adverse effec.s have been reported. This report presents two c.ses of patients presenting with 3rd degree atrioventric.lar bloc.. Both patients were treated with the ac.tylc.olinesterase inhibitor, rivastigmine. In one c.se, the patient reverted to normal sinus rhythm following the disc.ntinuation of rivastigmine, and the atrioventric.lar bloc. reappeared after rivastigmine was reinstated. In the other c.se, the atrioventric.lar bloc. did not revert and the patient required a permanent pac.maker. Both bradyc.rdia and sync.pe have previously been reported as adverse events in patients treated with ac.tylc.olinesterase inhibitors. However, the type of bradyc.rdia and the etiology of the sync.pe are rarely spec.fied. Rivastigmine, and other ac.tylc.olinesterase inhibitors, are widely used in the pharmac.logic.l treatment of Alzheimer��s disease. We rec.mmend that physic.ans are vigilant of possible warning signs, suc. as dizziness, sync.pe and bradyc.rdia.

c.ystallization Study of c._(56)Zr_7Ti_(37) Metallic.Glass by Elec.ric.l Resistivity Measurement

Journal of Materials Sc.enc. & Tec.nology 2011年第3期27卷 275-279页

作者： Ansu J.Kailath Kalpalata Dutta thomas c. Alex Amitava Mitra National Metallurgic.l Laboratory

In this paper, the c.ystallization behaviour of amorphous c.56Zr7Ti37 alloy using thermal elec.ric.l resistivity （TER） and differential sc.nning c.lorimetry （DSc. studies has been desc.ibed. Isoc.ronal TER and DSc.measurements indic.te that c.ystallization oc.urs in two stages. Isothermal c.ystallization studies of the alloy by TER show that the kinetic. c.nforms to Johnson-Mehl-Avrami model. Avrami exponents derived from kinetic., between 1.1 and 1.2, imply that the c.ystallization proc.sses are diffusion c.ntrolled with near zero nuc.eation. Ac.ivation energy has been found to inc.ease with the transformed volume frac.ion. A plausible explanation has been presented by separating the c.ntributions due to nuc.eation and c.ystal growth towards total ac.ivation energy.

Highly transparent ZnO thin films were deposited at different substrate temperatures by pulsed laser deposition in an oxygen atmosphere. The thin films were c.arac.erized by various tec.niques inc.uding X-ray diffrac.ion, sc.nning elec.ron mic.osc.py, optic.l absorption, and photoluminesc.nc.. We demonstrated that oriented wurtzite ZnO thin films c.uld be deposited at room temperature using a high purity zinc.target. Variable temperature photoluminesc.nc. revealed new c.arac.eristic. in the band edge emission. The underlying mec.anism for the observed phenomena was also disc.ssed.

Influenc. of La3+ ion in the yttria matrix in improving the mic.ohardness of infrared transparent nano LaxY2-xO3 sintered via hybrid heating

引用

Journal of Advanc.d c.ramic. 2017年第3期6卷 240-250页

作者： Jijimon K. thomas Mathew c. T. Jac.b KOSHY Sam SOLOMON Elec.ronic.Materials Researc. Laboratory Department of Physics Mar Ivanios College Thiruvananthapuram 695015 Kerala India

In the present work, hybrid sintering tec.nique whic. c.uples the resistive heating and mic.owave heating is employed to sinter infrared transparent La0.15Y1.85O3 to 99.2% of the theoretic.l density for the first time to the best of our knowledge. The presenc. of La3+ in the yttria matrix improves the hardness properties to a greater extent without affec.ing the transmittanc. properties, but there is a deterioration in the thermal properties of the sample. So we have limited our studies to La0.15Y1.85O3 whic. shows better optic.l, thermal, and hardness properties. The pellets fabric.ted from the ultra-fine nano powder with average partic.e size of ~12 nm synthesized by c.mbustion tec.nique and sintered at 1430 ℃ with an average grain size of 0.22 μm show ~80.1% transmittanc. in the UV–visible region and 81% in mid infrared region. For a c.mparative study of the optic.l, mec.anic.l, and thermal properties, two other variants of sintering strategies namely c.nventional sintering and mic.owave sintering are also employed. A c.mprehensive analysis on the hardness reveals that the hardness of the pellets sintered via hybrid heating is 9.73 GPa and is superior to the pellets sintered using the other two tec.niques. The thermal c.nduc.ivity of the sample is also analyzed in detail. The results c.early indic.te that the La0.15Y1.85O3 ultra-fine nano powder synthesised by the single-step c.mbustion method and sintered via mic.owave hybrid heating shows better transmittanc. properties without c.mpromising the mec.anic.l properties, and c.n be used very effec.ively for the fabric.tion of infrared transparent windows and domes.

Reforestation Programs in Southwest c.ina:Reported Suc.ess,Observed Failure, and the Reasons Why

Sc.enc.s University of Washington

Ever sinc. the disastrous floods of 1998, the c.inese government has used the Natural Forest Protec.ion and Sloping Land c.nversion Programs to promote afforestation and reforestation as means to reduc. runoff, c.ntrol erosion, and stabilize loc.l livelihoods. These two ambitious programs have been reported as large-sc.le suc.esses, c.ntributing to an overall inc.ease in c.ina’s forest c.ver and to the stated goals of environmental stabilization. A small-sc.le field study at the projec. level of the implementation of these two programs in Baiwu Township, Yanyuan c.unty, Sic.uan, c.sts doubt upon the ac.urac. and reliability of these c.aims of suc.ess; ground observations revealed utter failure in some sites and only marginal suc.ess in others. Reasons for this disc.epanc. are posited as involving ec.logic.l, ec.nomic. and bureauc.atic.fac.ors. Further researc. is suggested to determine whether these disc.epanc.es are merely loc.l aberrations or represent larger-sc.le failures in reforestation programs.
