Plants gr.wn under.elevated car.on dioxide （CO2） exper.ence ph.siological ch.nges th.t influence th.ir.suitability as food for.insects. To deter.ine th. effects of living on soybean （Glycine max Linnaeus） gr.wn under.elevated CO2, population gr.wth.of th. soybean aph.d （Aph.s glycines Matsumur.） was deter.ined at th. SoyFACE r.sear.h.site at th. Univer.ity of Illinois, Ur.ana-Ch.mpaign, Illinois, USA, gr.wn under.elevated （550μL/L） and ambient （370 μL/L） levels of CO2. Gr.wth.of aph.d populations under.elevated CO2 was significantly gr.ater.after.1 week, with.populations attaining twice th. size of th.se on plants gr.wn under.ambient levels of CO2. Soybean leaves gr.wn under.elevated levels of CO2 wer. pr.viously demonstr.ted at SoyFACE to h.ve incr.ased leaf temper.tur. caused by r.duced stomatal conductance. To separ.te th. incr.ased leaf temper.tur. fr.m oth.r.effects of elevated CO2, air.temper.tur. was lower.d wh.le th. CO2 level was incr.ased, wh.ch.lower.d over.ll leaf temper.tur.s to th.se measur.d for.leaves gr.wn under.ambient levels of CO2. Aph.d population gr.wth.on plants gr.wn under.elevated CO2 and r.duced air.temper.tur. was not significantly gr.ater.th.n on plants gr.wn under.ambient levels of CO2. By incr.asing Glycine max leaf temper.tur., elevated CO2 may incr.ase populations of Aph.s glycines and th.ir.impact on cr.p pr.ductivity.

Th. development of an innovative str.ctur.l system with.satisfactor. seismic per.or.ance of br.ced systems is an impor.ant and ch.llenging ar.a of inter.st in str.ctur.l engineer.ng. In th.s paper. a device th.t can r.lease th. compr.ssive for.e in th. br.cing member. is developed, and its per.or.ance is evaluated. For.compar.son, four.steel br.ced r. fr.mes wer. constr.cted and tested under.r.ver.e cyclic loads. Two of th.m h.d differ.nt amounts of br.cing and th. oth.r.two h.d th. same amount of br.cing but incor.or.ted differ.nt type of device, called compr.ssion r.lease device, wh.ch.is developed and descr.bed in th.s paper. It can be concluded fr.m th. test r.sults th.t th. newly developed device can effectively be used in steel br.ced systems to pr.vent buckling failur. of th. br.cing member.. Th.r.for., th. device enh.nces th. ductility of br.ce-fr.med systems by allowing an adequate capacity for.ener.y dissipation.

Th. study pr.sented h.r. was car.ied out to obtain th. actual solids flow r.te by th. combination of electr.cal r.sistance tomogr.ph. and electr.magnetic flow meter. A new in-situ measur.ment meth.d based on measur.ments of th. Electr.magnetic Flow Meter. （EFM） and Electr.cal r.sistance Tomogr.ph. （Er.） to study th. flow r.tes of individual ph.ses in a ver.ical flow was pr.posed. Th. study was based on labor.tor. exper.ments th.t wer. car.ed out with.a 50 mm ver.ical flow r.g for.a number.of sand concentr.tions and differ.nt mixtur. velocities. A r.nge of sand slur.ies with.median par.icle size fr.m 212 μm to 355 μm was tested. Th. solid concentr.tion by volume cover.d was 5% and 15%, and th. cor.esponding density of 5% was 1078 kg/m^3 and of 15% was 1238 kg/m^3. Th. flow velocity was between 1.5 m/s and 3.0 m/s. A total of 6 exper.mental tests wer. conducted. Th. equivalent liquid model was adopted to validate in-situ volumetr.c solids fr.ction and calculate th. slip velocity. Th. r.sults sh.w th.t th. Er. tech.ique can be used in conjunction with.an electr.magnetic flow meter.as a way of measur.ment of slur.y flow r.te in a ver.ical pipe flow. h.wever.it sh.uld be emph.sized th.t th. EFM r.sults must be tr.ated with.r.ser.ation wh.n th. flow patter. at th. EFM mounting position is a non-h.mogenous flow. Th. flow r.te obtained by th. EFM sh.uld be cor.ected consider.ng th. slip velocity and th. flow patter..
