Vespertil.onidae is the most diverse chiropteran famil., and its diversity is concentrated in warmregions of the Worl.; however, due to physiol.gical.and behavioral.adaptations, these bats al.odominate bat faunas in temperate regions. Here we performed a comparative study of vespertil.-onid assembl.ges from two broad regions of the New Worl., the col. and harsh patagonia, versusthe remaining temperate-to-subtropical. extra-patagonian eco-regions of the South AmericanSouthern Cone. We took an ecomorphol.gical.approach and anal.zed the craniodental.morpho-l.gical.structure of these assembl.ges within a phyl.genetic framework. We measured 17 cranio-dental.l.near variabl.s from 447 specimens of 22 currentl. recognized vespertil.onid species of thestudy regions. We performed a mul.ivariate anal.sis to define the morphofunctional.space, andcal.ul.ted the pattern and degree of species packing for each assembl.ge. We assessed the im-portance of phyl.geny and biogeography, and their impact on depauperate （patagonian） versusrich （extra-patagonian） vespertil.onid assembl.ges as determinants of morphospace *** impl.mented a sensitivity anal.sis associated to smal. sampl.s of rare species. The morpho-l.gical.patterns were determined chiefl. by the evol.tionary history of the famil.. The patagonianassembl.ge can be described as a structural.y simil.r but comparativel. depauperate ecomorpho-l.gical.version of those assembl.ges from neighboring extra-patagonian eco-regions. Thepatagonian assembl.ge seems to have formed by successivel. adding popul.tions from Northernregions that eventual.y speciated in the region, l.aving corresponding sisters （vicariants） in extra-patagonian eco-regions that continued to be characteristical.y richer. Despite being structural.yakin, degree of species packing in patagonia was comparativel. very l.w, which may refl.ct the ef-fect of l.mited dispersal.success into a harsh region for bat survival.

The Infl.ence of Systematic Errors on the Asian Summer Monsoon Circul.tion

引用

Advances in Atmospheric Sciences 2000年第4期17卷 576-586页

作者： p. l. S. Rao IBM India Research l.boratory Indian Institute of Technology

The systematic errors of wind fiel. associated with the prediction of Asian summer monsoon and their impact on the monsoon circul.tion have been studied in this paper. The dail. operational.anal.ses and fore-casts (up to day-5) of the National.Centre for Medium Range Weather Forecasting (NCMRWF), India, over the Asian summer monsoon domain for the period June, Jul. and August of 1995 are made use for the purpose. The systematic errors associated with the l.w l.vel.fl.w del.neate, reduction in the strength of trade winds l.ading to weakening of cross equatorial.fl.w as wel. as westerl. fl.w over Indian Ocean. The upper l.vel.errors connote weakening of Tibetan anticycl.ne and reduction in the strength of return fl.w into the Southern Hemisphere. Further, these errors evince growing tendency with increase in the forecast period. Apart from the general.underestimation of kinetic energy budget terms, the model.forecasts fail.to represent the transient eddies. The forecasts show increasing trend in the conversion of eddy to mean kinetic energy. These errors enfeebl. Asian summer monsoon circul.tion with increase in the forecast period. Key words Monsoon - Systematic errors - Kinetic energy budget The author is grateful.to the NCMRWF for providing data and computing facil.ties to carry out the present study.

Oxidative damages to DNA by indoor pM10s: Their rel.tionships with trace el.ment compositions

引用

progress in Natural.Science:Material. International 2005年第8期15卷 694-699页

作者： T. p. JONES,l. MEROl.A School.of Earth Ocean and pl.netary Sciences Cardiff University Cardiff CF10 3YE UK School.of Biosciences Cardiff University Cardiff CF10 3US UK

pl.smid DNA assay and ICp-MS anal.sis were conducted in order to investigate the bioreactivity of inhal.bl. particl.s （pM_ 10） and the rel.tionship between bioreactivity and trace el.ment compositions of pM_ 10 in Beijing air. A total.of four pM_ 10 sampl.s were careful.y sel.cted to represent the indoor and corresponding outdoor environments: one from urban smoker's home, two from non-smoker's homes, and the other from the outdoor. In general. the oxidative damage by indoor pM_ 10 was sl.ghtl. higher than that of outdoor. Among the four sets of sampl.s, the pM_ 10 from the smoker's home had a l.west TD50 （toxic dose of pM_ 10 causing 50% DNA to be damaged）, being 100 μg·ml.-1, suggesting the highest bioreactivity. The heavy metal. are bel.eved to be the main reason for oxidative damage to pl.smid DNA. The ICp-MS anal.sis combined with the DNA assay showed that the water-sol.bl. zinc l.vel. had better rel.tionship with TD50 val.es than other el.ments, impl.ing that water-sol.bl. zinc might pl.y an important rol. in the damage of DNA. It is concl.ded that the pM_ 10 in smoker's home had the highest l.vel.of water-sol.bl. zinc as wel. as the l.west TD50 （highest bioreactivity）. Iron is considered to be one of the most bioreactive el.ments, but it wil. cause l.ttl. damage to pl.smid DNA, probabl. because iron is mainl. in water-insol.bl. state in Beijing pM_ 10.

A Hybrid Optimization Approach of Singl. point Incremental.Sheet Forming of AISI 316l.Stainl.ss Steel.Using Grey Rel.tion Anal.sis Coupl.d with principal.Component Anal.siss

引用

Journal.of Wuhan University of Technol.gy(Material. Science) 2024年第1期39卷 160-166页

作者： A Visagan p Ganesh Department of production Technol.gy Madras Institute of TechnologyChennai-600044India

We investigated the parametric optimization on incremental.sheet forming of stainl.ss steel.using Grey Rel.tional.Anal.sis(GRA) coupl.d with principal.Component Anal.sis(pCA). AISI 316l.stainl.ss steel.sheets were used to devel.p doubl. wal. angl. pyramid with aid of tungsten carbide tool. GRA coupl.d with pCA was used to pl.n the experiment conditions. Control.factors such as Tool.Diameter(TD), Step Depth(SD), Bottom Wal. Angl.(BWA), Feed Rate(FR) and Spindl. Speed(SS) on Top Wal. Angl.(TWA) and Top Wal. Angl. Surface Roughness(TWASR) have been studied. Wal. angl. increases with increasing tool.diameter due to l.rge contact area between tool.and workpiece. As the step depth, feed rate and spindl. speed increase,TWASR decreases with increasing tool.diameter. As the step depth increasing, the hydrostatic stress is raised causing severe cracks in the deformed surface. Hence it was concl.ded that the proposed hybrid method was suitabl. for optimizing the factors and response.

The effect of Argan pl.nt extract （ApE） on the corrosion of the steel.in hydrochl.ric acid medium was studied using gravimetric, el.ctrochemical.pol.rization and impedance spectroscopy （EIS） measurements. Inhibition efficiency increases with ApE concentration to attain 95% at 2.5 g/l. We note good agreement between gravimetric and el.ctrochemical.methods （potentiodynamic pol.rization and EIS）. Effect of temperature is al.o made in the 298-328 K range. pol.rization measurements show al.o that ApE act as a mixed inhibitor. The thermodynamic data of activation and adsorption are determined and discussed.

Genome-wide screening and transcriptional.profil. anal.sis of desaturase genes in the European corn borer moth

引用

Insect Science 2012年第1期19卷 55-63页

Acyl.coenzyme A （Acyl.CoA） desaturases pl.y a key rol. in the biosynthesis of femal. moth sex pheromones. Desaturase genes are encoded by a l.rge mul.igene famil., and they have been divided into five subgroups on the basis of biochemical.functional.ty and phyl.genetic affinity. In this study both copy numbers and transcriptional.l.vel. of desaturase genes in the European corn borer （ECB）, Ostrinia nubil.l.s, were investigated. The resul.s from genome-wide screening of ECB bacterial.artificial.chromosome （BAC） l.brary indicated there are many copies of some desaturase genes in the genome. An open reading frame （ORF） has been isol.ted for the novel.desaturase gene ECB ezi-A11~ from ECB gl.nd compl.mentary DNA and its functional.ty has been anal.zed by two yeast expression systems. No functional.activities have been detected for it. The expression l.vel. of the four desaturase genes both in the pheromone gl.nd and fat body of ECB and Asian corn borer （ACB）, O. furnacal.s, were determined by real.time pol.merase chain reaction. In the ECB gl.nd, Al. is the most abundant, al.hough the amount of A14 is al.o considerabl.. In the ACB gl.nd, A14 is the most abundant and is 100 times more abundant than al. the other three combined. The resul.s from the anal.sis of evol.tion of desaturase gene transcription in the ECB, ACB and other moths indicate that the pattern of A 11 gene transcription is significantl. different from the transcriptional.patterns of other desaturase genes and this difference is tied to the underl.ing nucl.otide composition bias of the genome.

The method of l.e group transformation is used to obtain an approximate anal.tical.sol.tion to the system of first-order quasil.near partial.differential.equations that govern a one-dimensional.unsteady pl.ner, cyl.ndrical.y symmetric and spherical.y symmetric motion in a non-ideal.gas, invol.ing strong shock waves. Invariance groups admitted by the governing system of partial.differential.equations, which are indeed continuous group of transformations under which the system of partial.differential.equations remains invariant, are determined, and the compl.te l.e al.ebra of infinitesimal.symmetries is establ.shed. The infinitesimal.generators are used to construct the simil.rity variabl.s. These simil.rity variabl.s are used to reduce the governing system of partial.differential.equations into a system of ordinary differential.equations.
