The a.a.ysis of tra.e elements in huma. ha.r for use a. bioma.kers continues to genera.e considera.le interest in environmenta. a.d bioa.a.ytica. studies, medica. dia.nostics, a.d forensic science. This study investiga.ed the concentra.ions of essentia. a.d toxic elements (Fe, Mg, Ca. Cu, Zn, Cr, Cd, a.d Pb) using fla.e a.omic a.sorption spectroscopy (Fa.S) in huma. sca.p ha.r obta.ned from subjects living in Forsyth County, North Ca.olina. USa. The influence of a.e, sex, ra.e, a.d smoking ha.its on the levels of tra.e elements in the ha.r sa.ples were a.so investiga.ed. a.ditiona.ly, a.a.yses were subjected to a.sta.istica., regression, a.d principa. component a.a.ysis to eva.ua.e inter-elementa. a.socia.ion a.d possible pa.tern recognition in ha.r sa.ples. Furthermore, Ca.Mg a.d Zn/Cu ra.ios, which a.e often used to eva.ua.e the degree of Ca.a.d Cu utiliza.ion in huma.s a.d a. ma.kers for va.ious hea.th rela.ed issues including, a.herosclerosis, hypertension, insulin sensitivity, a.d pa.crea.ic ca.cer, were ca.cula.ed. The overa.l mea. concentra.ions of Fe (25 μg/g), Ca.(710 μg/g), Mg (120 μg/g), Zn (190 μg/g), Cu (12 μg/g), a.d Cr (0.20 μg/g) were found in ha.r sa.ples. The tra.e element concentra.ions va.ied widely in ha.r sa.ples a. demonstra.ed by la.ge ra.ge of concentra.ions obta.ned for ea.h element. However, levels of Cd a.d Pb elements of a.r sa.ple. In genera., the levels of the tra.e elements in ha.r sa.ples were poorly correla.ed. However, significa.t correla.ions were found between Ca.a.d Mg (r = 0.840, p = 0.05). The levels of Fe, Ca. Mg, Zn, Cu, a.d Cr in ha.r sa.ples a.d the ca.cula.ed Ca.Mg a.d Zn/Cu ra.ios were found to be la.gely correla.ed with a.e, ra.e, sex, a.d smoking ha.its.

This study investiga.ed the potentia. utility of poly (sodium N-undeca.oyl-L-leucyl-va.ina.e) (poly-L-SULV), poly (sodium N-undeca.oyl-L-leucyl-a.a.a.e) (poly-L-SULa., a.d poly (sodium N-undeca.oyl-glycina.e) (poly-SUG) molecula. micelles (MMs) a. chela.ors for hea.y meta.

D-optimum experimenta. design wa. employed to simulta.eously investiga.e the influence of design va.ia.les such a. the buffer pH, chela.or concentra.ion, a.d centrifuge speed to eva.ua.e the optimum conditions a.d to reduce the time a.d cost of meta. ion remedia.ion. The pa.tition coefficients of the meta. ion concentra.ions between the ka.linite cla. a.d chela.or equilibrium were a.so eva.ua.ed. In a.dition, the influence of meta. ion concentra.ions on the remedia.ion ca.a.ility of the chela.ors wa. eva.ua.ed by conducting remedia.ion studies a. four different (10 ppm, 40 ppm, 60 ppm, a.d 80 ppm) meta. ion concentra.ions. In genera., the results of the remedia.ion efficiency a.d pa.tition coefficients obta.ned in this study a.e highly meta. ion dependent a.d a.so dependent upon the chela.or used for the remedia.ion. Specifica.ly, the remedia.ion efficiency of the molecula. micelles wa. found to be compa.a.le to or better tha. the corresponding remedia.ion efficiency obta.ned when SDS or EDTa.wa. used for the remedia.ion. However, a. optimum conditions, poly-SULV a.d poly-L-SULa.molecula. micelle chela.ors demonstra.ed superior remedia.ion efficiencies for Cr, with remedia.ion efficiency of 99.9 ± 8.7% a.d 99.1 ± 0.7%, respectively.

a.conceptua. coa.ia. Pitot tube （PT） ha. been developed using fiber optic sensors combined with a.tua.ors to monitor a.d ma.nta.n its correct opera.ion under different environmenta. conditions. Experiments were performed showing tha. the dyna.ic a.d sta.ic tubes ca. be clea.ed of ice. It wa. a.so demonstra.ed tha. the dyna.ic tube could be clea.ed of dust a.d sa.d which wa. not the ca.e for the sta.ic tube in the coa.ia. configura.ion. a. a.proa.h wa. proposed to overcome this problem involving a.conventiona. configura.ion where the sta.ic tube wa. opera.ed independently orthogona. to the dyna.ic tube, a.d a.second set of sensors a.d a.tua.ors wa. used. Sensors a.d a.socia.ed a.tua.ors were developed for tempera.ure a.d intensity for a.linea. PT. The a.m of this work is to propose a.solution for a.problem tha. ha. ca.sed the loss of the lives of ma.y pa.sengers a.d crew of a.rcra.t.

a.funda.enta. objective within ecotoxicology lies in understa.ding a.d predicting effects of conta.ina.ts. This ob- jective is ma.e more cha.lenging when globa. clima.e cha.ge is considered a. a. environmenta. stress tha. co-occurs with con- ta.ina.t exposure. In this multi-stressor context, evolutiona.y processes a.e pa.ticula.ly importa.t. In this pa.er, we consider severa. non-＂omic＂ a.proa.hes wherein evolutiona.y responses to stress ha.e been studied a.d discuss those a.ena.le to a.mul- tiple stressor context. Specifica.ly, we discuss common-ga.den designs, a.tificia. a.d qua.i-na.ura. selection, a.d the estima.ion of a.a.tive potentia. using qua.tita.ive genetics a. methods for studying evolutiona.y responses to conta.ina.ts a.d clima.e cha.ge in the a.sence of expensive molecula. tools. While a.l a.proa.hes shed light on potentia. evolutiona.y impa.ts of stressor exposure, they a.so ha.e limita.ions. These include logistica. constra.nts, difficulty extra.ola.ing to rea. systems, a.d responses tied strongly to specific ta.a. popula.ions, a.d/or testing conditions. The most effective wa. to lessen these inherent limita.ions is likely through inclusion of complementa.y physiologica. a.d molecula. tools, when a.a.la.le. We believe tha. a. evolutiona.y context to the study of conta.ina.ts a.d globa. clima.e cha.ge is a.high priority in ecotoxicology a.d we outline methods tha. ca. be implemented by a.most a.y resea.cher but will a.so provide va.ua.le insights [Current Zoology 61 （4）： 690-701, 2015].

多年前我买了一本书,名叫《汉语虚词英译》,孙瑞禾编著,1981年出版,定价2.10元,六百多页,看来很值钱。打开一看,内容果然很丰富,同时也有点让人惊奇。它总共选收了30个汉语虚词,每项列出多至40个不同的英文表达法,真是出乎意表的数目。起初怀疑有牵强附会的,仔细读来也不是,对应都有根据。读这本书等于上灵活翻译一门课。
