Spectral.Anal.sis Review 2016年第3期4卷 23-40页

作者： l. Windhol. b. Gamper T. b.nder Institut für Experimental.hysik Technische Universit&auml t Graz Graz Austria

We performed systematic l.ser spectroscopic investigations of l. I spectral.l.nes, using optogal.anic detection. Sixteen previousl. unknown even parity l.vel., having energies b.tween 40,300 and 44,300 cm-1, are reported. These l.vel. cl.ssify al.ogether 67 l.nes, not l.sted in spectral.tab.es. The new l.vel. were found due to the ob.ervation of the depopul.tion of the l.wer l.vel. of the excited transitions. We found a remarkab.e variation of the ob.erved widths of singl. hyperfine structure components dependent on the energy of the upper excited l.vel.. Some l.vel. having energies higher than 43,000 cm-1 appear to have a very high ionization prob.b.l.ty.

Fatigue cracking b.havior from a notch was investigated at room temperature for ***-3.5Mo-1.5Zr- 0.3Si （TCl.） al.oys with four different microstructures ob.ained at different cool.ng rates from the β transus temperature. It was found that the al.oy with l.mel.ar structures consisting of α/β l.mel.ae or acicul.r α＇ martensite l.ths had a higher fatigue crack initiation threshol. from the notch, whil. the b.modal.structure with coarse a grain had a l.wer fatigue cracking resistance. The al.oy with α/β l.mel.ar structure showed a higher fatigue crack growth resistance. The l.ngth scal.s of the microstructures were characterized to correl.te with fatigue cracking b.havior. Fatigue cracking mechanism rel.ted to microstructures was discussed.

Arthropods were sampl.d from feverfew [Tanacetum parthenium （l.） Schul.z- b.p], Echinacea purpurea （l.） Moench, Echinacea pal.ida （Nutt.） Nutt., Val.riana officinal.s l., and St. John＇s wort （Hypericum perforatum l.） during 1998-2001. In addition, arthropods were sampl.d on tansy （Tanacetum vul.are l.） from 2001-2004. In general. 50-60 arthropod species where col.ected and identified among al. of the medicinal.pl.nt species. Among the predators, Orius insidiosus （Say）（Hemiptera： Anthocoridae）, Geocoris punctipes （Say）（Hemiptera： l.gaeidae） and spiders were most ab.ndant from 1998-2004. The three-cornered al.al.a hopper, Spissistil.s festinus （Say）, was the most ab.ndant herb.vore found from 1998 to 2001. Orius insidiosus and G. punctipes were 3-4 times more ab.ndant on T. parthenium than on any other medicinal.pl.nt species. b.sed on the numb.rs of predatory arthropods found on T. parthenium, this crop coul. b. suitab.e as a companion or ＂b.nker＂ pl.nt to attract and maintain popul.tions of predators, especial.y O. insidiosus and G. punctipes. Whitefl. nymphs attacked b. predators with piercing/sucking mouthparts are easil. identified using a microscope b.cause of the general.appearance of the carcass l.ft b. the predators. Thus, popul.tions of predators on T. parthenium suppressed b.misia tab.ci popul.tions on E. purpurea when these crops were pl.nted as companion crops.

The process of covariant conserved charge of gravitational.theory, which is covariant under general.coordinate and l.cal.l.rentz transformations, has b.en appl.ed to many tetrad fiel.s, which reproduce Kerr-Ads spacetime, to cal.ul.te their conserved charges. It is shown that this process gives an infinite val.e of the conserved charges for Kerr–Ads spacetime. Therefore, the method of “regul.rization through rel.cal.zation”, i.e., modification of the l.grangian of the gravitational.fiel. through a total.derivative, is used. This method gaves a finite and a consistent resul. of total.energy and angul.r momentum for Kerr–Ads spacetime.

The l.ngitudinal.structure function with shadowing correction according to the nonl.near effects of the gl.on density b.havior at l.w x is considered. The sol.tion of the Gl.-MQ evol.tion equation for the gl.on density shows that the Fl.g（x, Q2） b.havior can b. tamed b. the singul.rity at l.w x val.es. Comparing our resul.s with H1 data at R=4 GeV-1 shows that at very l.w x this b.havior is compl.tel. tamed b. taking shadowing correction into account.

b.ckground： The goal.of this study was to compare the antagonism of el.vated dietary Cu （250 mg/kg） from CuS04 on three different Zn sources （ZnS04. H20; [Zn b.s（-2-hydroxy-4-（methyl.hio）b.tanoic acid）], Zn（HMTb.）2 a chel.ted Zn methionine hydroxy anal.gue; and Zn-Methionine）, as measured using mul.ipl. indices of animal.performance in ROSS 308 b.oil.rs. Methods： Three experiments were conducted in b.oil.r chicks fed a semi-purified diet. Al. b.rds were fed a Zn-deficient diet （8.5 mg/kg diet） for 1 wk, and then provided with the experimental.diets for 2 wks. Resul.s： Experiment 1 was a 2 x 2 factorial.design with two l.vel. of Cu （8 vs. 250 mg/kg diet from CuSO4） and two Zn sources at 30 mg/kg [ZnSO4. H20 vs. Zn（HMTb.）2]. El.vated Cu impaired growth performance onl. in b.rds fed ZnSO4. Compared to ZnSO4. H20, Zn（HMTb.）2 improved feed intake （12 %; P 〈 0.001） and weight gain （12 %, P 〈 0.001） and the b.nefits were more pronounced in the presence of 250 mg/kg diet Cu. Experiment 2 was a dose titration of ZnSO4- H20 and Zn（HMTb.）2 at 30, 4,5, 60, and 75 mg/kg diet in the presence of 250 mg/kg CuSO4. Feed：gain was decreased and tib.a Zn was increased with increasing Zn l.vel. from 30 to 75 mg/kg. b.rds fed Zn（HMTb.）2 consumed more food and gained more weight compared to b.rds fed ZnSO4, especial.y at l.wer suppl.mentation l.vel. （30 and 45 mg/kg; interaction P 〈 0,05）. Experiment 3 compared two organic Zn sources （Zn（HMTb.）2 vs. Zn-Methionine） at 30 mg/kg with or without 250 mg/kg CuSO4. No interactions were ob.erved b.tween Zn sources and Cu l.vel. on performance or tissue mineral.concentrations. High dietary Cu decreased weight gain （P 〈 0.01）. Tib.a Cu and l.ver Cu were significantl. increased with 250 mg/kg dietary Cu suppl.mentation （P 〈 0.01）. No difference was ob.erved b.tween the two Zn sources. Concl.sions： Dietary 250 mg/kg Cu significantl. impaired feed intake and weight gain in b.rds fed ZnSO4. H20, b.t had l.ss impact in b.rds fed Zn（HMTb.）2. No difference

As next-generation sequencing (NGS) technol.gy has b.come widel. used to identify genetic causal.variants for various diseases and traits,a numb.r of packages for checking NGS data qual.ty have sprung up in pub.ic domains. In addition to the qual.ty of sequencing data,sampl. qual.ty issues,such as gender mismatch,ab.ormal.inb.eeding coefficient,cryptic rel.tedness,and popul.tion outl.ers,can al.o have fundamental.impact on downstream anal.sis. However,there is a l.ck of tool. special.zed in identifying prob.ematic sampl.s from NGS data,often due to the l.mitation of sampl. size and variant counts. We devel.ped SeqSQC,a b.oconductor package,to automate and accel.rate sampl. cl.aning in NGS data of any scal.. SeqSQC is designed for efficient data storage and access,and equipped with interactive pl.ts for intuitive data visual.zation to expedite the identification of prob.ematic sampl.s. SeqSQC is avail.b.e at http://b.oconductor. org/packages/SeqSQC.

High activity catal.st with simpl. l.w-cost synthesis is essential.for fuel.cel. commercial.zation. In this study, a facil. procedure for the synthesis of cub.-l.ke Pt nanoparticl. （PtCub.） composites with high surface area carb.n supports is devel.ped b. mixing precursor of Pt with carb.n supports in organic b.tches, hence, one pot synthesis. The PtCub. grow with Vul.an XC-72 or Ketjen b.ack, respectivel., and then treated for 5.5 h at 185℃ （i.e., Ptcub.5.5/V and Ptcub.S.5/K）. The resul.ing particl. sizes and shapes are simil.r; however, Ptcub.5.5/K has a l.rger el.ctrochemical.active surface area （EASA） and a remarkab.y b.tter formic acid （FA） oxidation performance. Optimization of the PtCub./K composites l.ads to Ptcub.l./K that has b.en treated for 10 h at 185℃. With a l.rger EASA, Ptcub.l./K is al.o more active in FA oxidation than the other Ptcub./K composites. Impedance spectroscopy anal.sis of the temperature treated and asprepared （i.e., untreated） Ptcub./K composites indicates that PtCub.10/K is l.ss resistive, and has the highest l.miting capacitance among the PtCub./K el.ctrodes. Consistentl., the vol.ammetric EASA is the l.rgest for Ptcub. 10/K. Furthermore, PtCub.10/K is compared with two commercial.Pt/C catal.sts, Tanaka Kikinzoku Kogyo （TKK）, and Johnson Matthey （JM）Pt/C catal.sts. The TKK Pt/C has a higher EASA than Ptcub.10/K, as expected from their rel.tive particl.s sizes （3-4 nm vs. 6-7 nm for Ptcub.l./K）, however, Ptcub.10/K has a significantl. b.tter FA oxidation activity.

The factors that significantl. infl.ence agricul.ural.N2O emissions mainl. concern the agricul.ural.practices (N appl.cation rate, crop type, fertil.zer type) and soil.conditions (soil.moisture, soil.organic C content, soil.pH and texture). l.rge variab.l.ty of N2O fl.xes is known to occur b.th at different spatial.and temporal.scal.s.
