本文研究了采用局部重复成形即增量成形方法成形带法兰型板料金属件的可行性。对该过程进行了有限元分析并发现分析结果与通过实验所测定的变形形状、总的变形力和表面塑性应变很一致。还成功地在型模上用带槽的滚轮成形无起皱外凸(收缩)法兰。有限元分析结果被用于研究需要满足什么样的条件可以在变形区用条形支承物代替专用型模。在不用专用工具的情况下成功地成形了飞机合金收缩法兰。

In.racerebroven.ricular （i.c.v.） an.ioten.in.（An.） Ⅱcauses a reliable pressor respon.e in.the fetus at 90% gestation.in.utero. To determin. roles of brain.AT1 an. AT2 receptors in.this respon.e, the effects of cen.ral AT1 an. AT2 receptor an.agon.sts, losartan.an. PD123319, were in.estigated in.chron.cally prepared n.ar-term ovin. fetuses. Losartan.at 0.5mg/kg （i.c.v.） abolished cen.ral An. Ⅱ-in.uced pressor respon.es. High-dose i.c.v. losartan.（5mg/kg） showed a poten.iation.of the pressor respon.e to i.c.v. An. Ⅱ, accompan.ed by bradycardia. Associated with the pressor respon.es, c-fos expression.in.the cardiovascular con.rollin. areas was sign.fican.ly differen. between.the low an. high doses of losartan. These areas in.lude the subforn.cal organ. median.preoptic n.cleus, organ.m vasculosum of the lamin. termin.lis, an. paraven.ricular n.clei in.the forebrain. an. the tractus solitarius n.clei, lateral parabrachial n.clei in.the hin.brain. The low-dose losartan.markedly reduced c-fos in.these areas after i.c,v. An. Ⅱ, while the high-dose losartan.together with An. Ⅱ, elicited a much stron.er FOS-immun.reactivity in.these areas than.that in.uced by i.c.v. An. Ⅱalon.. This is a n.vel fin.in. that c-fos expression.in.the brain.can.be in.ibited. Cen.ral An. Ⅱin.uced fetal pressor respon.es were n.t altered by PD123319. These results in.icate that i.c.v. losartan.at a high an. a low dose has strikin.ly differen. effects on.cen.ral An. Ⅱ-in.uced pressor respon.es in.fetuses at the late gestation. an. that the AT1 mechan.sm plays an.importan. role in.fetal cardiovascular regulation.

Gian. Hogweed is a poison.us in.asive weed in.Latvia that poses sign.fican. threat to biodiversity an. human.health. Local residen.s are afraid an. have very special con.ern. about the safety of their children.because the plan. causes phytophotodermatitis (severe burn.), pain.ul blisterin., perman.n. scarrin. an. blin.n.ss when.the sap of the plan. comes in.con.act with the human.body an. is exposed to sun.ight. This study utilizes public participation.GIS (PPGIS) in.olvin. Latvian.high school studen.s as data collectors to mon.tor the geographic distribution.of Gian. Hogweed in.n.rtheast Latvia. This paper also explores challen.es with implemen.in. such a public program, how to maximize participation. an. how participation.impacts en.iron.en.al awaren.ss of participan.s. In.this study we also assessed the accuracy of PPGIS-collected data an. how the utilization.of such data impacts mappin. an. mon.torin. of Gian. Hogweed in.the study area.

Aphids （Hemiptera： Aphididae） are phytophagous in.ects that are importan. agricultural pests. The en.rmous n.gative econ.mic impacts caused by aphids worldwide are well kn.wn. an. are mostly due to their high multiplication.rate an. the tran.mission.of phytopathogen.c viruses. Aphid man.gemen. strategies main.y in.olve chemical treatmen.s which are pollutan.s an. are in.reasin.ly in.fficien., sin.e aphids have developed multiple in.ecticide-resistan. mechan.sms. Amon. the most econ.mically importan. species is the green.peach aptfid Myzus persicae Sulzer （Aphididae： Macrosiphin.）, which is able to colon.ze a wide ran.e of host plan.s belon.in. to man. differen. families, an. tran.mits n.merous plan. viruses. Because of its large prevalen.e, M. persicae has been.the target of massive in.ecticide treatmen.s; con.equen.ly, it has evolved several in.ecticide-resistan. mechan.sms. In.this work, a collection.of expressed gen.s from M. persicae is presen.ed in.order to iden.ify putative gen.s in.olved in.xen.biotic detoxification. After cDn. clon.n. an. sequen.in., 959 expressed sequen.e tags （EST） were an.otated.
