With ever increasing water dem.nds and the continuous intensification of water scarcity arising from.China＇s industrial.zation, the country is struggl.ng to harm.nize its industrial.devel.pm.nt and water suppl.. This paper presents a system. anal.sis of water with- drawal. by Chinese industry and investigates dem.nd- driven industrial.water uses em.odied in final.dem.nd and interregional.trade based on a m.l.i-regional.input-output m.del. In 2007, the El.ctric Power, Steam. and Hot Water Production and Suppl. sector ranks first in direct industrial.water withdrawal.（DWW）, and Construction has the l.rgest em.odied industrial.water use （EWU）. Investm.nt, consum.tion, and exports contribute to 34.6%, 33.3%, and 30.6% of the national.total.EWU, respectivel.. Specifical.y, 58.0%, 51.1%, 48.6%, 43.3%, and 37.5% of the regional.EWUs respectivel. in Guangdong, Shanghai, Zhejiang, Jiangsu, and Fujian are attributed to international.exports. The total.interregional.im.ort/export of em.odied water is equival.nt to about 40% of the national.total.DWW, of which 55.5% is associated with the DWWs of El.ctric Power, Steam. and Hot Water Production and Suppl.. Jiangsu is the biggest interregional.exporter and deficit receiver of em.odied water, in contrast to Guangdong as the biggest interregional.im.orter and surpl.s receiver. Without im.l.m.nting effective water- saving m.asures and adjusting industrial.structures, the regional.im.al.nce between water avail.bil.ty and water dem.nd tends to intensify considering the water im.act of dom.stic trade of industrial.products. Steps taken to im.rove water use efficiency in production, and to enhance em.odied water saving in consum.tion are both of great significance for supporting China＇s water pol.cies.

A robust sl.ding m.de approach com.ined with a fiel. oriented control.（FOC） for induction m.tor （Im. speed control.is presented. The proposed sl.ding m.de control.（Sm.） design uses an adaptive switching gain and an integrator. This approach guarantees the sam. robustness and dynam.c perform.nce of traditional.Sm. al.orithm.. And at the sam. tim., it attenuates the chattering phenom.non, which is the m.in drawback in actual.im.l.m.ntation of this technique. This approach is insensitive to uncertainties and perm.ts to decrease the requirem.nt for the bound of these uncertainties. The stabil.ty and robustness of the cl.sed- l.op system.are proven anal.tical.y using the l.apunov synthesis approach. The proposed m.thod attenuates the effect of both uncertainties and external.disturbances. Experim.ntal.resul.s are presented to val.date the effectiveness and the good perform.nce of the devel.ped m.thod.

Al.hough the functional.neuroanatom. of the m.dbrain dopam.ne （m.A） system.has been wel. characterized, the l.terature regarding its capacity to innervate the hippocam.al.form.tion has been inconsistent. The l.ck of expression of definitive m.rkers for dopam.nergic fibers, such as the dopam.ne transporter, in the hippocam.us has com.l.cated studies in this area. Here we have used im.unohistochem.cal.techniques to characterize the tyrosine hydroxyl.se expressing fiber network in the rat hippocam.us, com.ined with retrograde tracing from.the dentate gyrus to assess the capacity for afferent innervation by m.A neurons. The resul.s indicate that virtual.y al. tyrosine hydroxyl.se fibers throughout the hippocam.us are of a noradrenergic phenotype, whil. the overl.ing cortex contains both dopam.nergic and noradrenergic fiber networks. Furtherm.re, retrograde tracing from.the dentate gyrus robustl. l.bel. tyrosine hydroxyl.se-im.unoreactive noradrenergic neurons in the l.cus coerul.us but not m.A neurons.

Sim.l.ted m.crogravity （Sm.） bioreactors and DNA m.croarray technol.gy are powerful.tool. to identify ＂space genes＂ that pl.y key rol.s in cel.ul.r response to m.crogravity. We appl.ed these biotechnol.gy tool. to investigate Sm. and post-Sm. recovery effects on hum.n epiderm.l.keratinocytes by exposing cel.s to Sm. for 3, 4, 9, and 10 d using the high aspect ratio vessel.bioreactor fol.owed by recovery cul.uring for 15, 50, and 60 d in norm.l.gravity. As a resul., we identified 162 differential.y expressed genes, 32 of which were ＂center genes＂ that were m.st consistentl. affected in the tim. course experim.nts. El.ven of the center genes were from.the integrated stress response pathways and were coordinatel. downregul.ted. Another seven of the center genes, which are al. m.tal.othionein m.-Ⅰ and m.-Ⅱ isoform., were coordinatel. up-regul.ted. In addition, Hl.-G, a key gene in cel.ul.r im.une response suppression, was found to be significantl. upregul.ted during the recovery phase. Overal., m.re than 80% of the differential.y expressed genes from.the shorter exposures （≤4 d） recovered in 15 d; for l.nger （≥9 d） exposures, m.re than 50 d were needed to recover to the im.act l.vel.of shorter exposures. The data indicated that shorter Sm. exposure duration woul. l.ad to quicker and m.re com.l.te recovery from.the m.crogravity effect.

Today there is a big interest in reducing the m.intenance costs and in increasing the rel.abil.ty of m.chines in continuous operation. Therefore, m.intenance on condition is used. State-of-the-art is a trend anal.sis and a faul. prediction m.de onl. based on sensor signal. and stochastic m.thods. The identification possibil.ties of this technique are l.m.ted. A new concept for m.del.based m.nitoring has been devel.ped for m.re detail.d faul. identification. The devel.ped concept determ.nes the condition of a m.chine after the occurrence of a faul.. The concept is based on a sim.l.tion incl.ding various faul.s and an optim.zation tool. The devel.pm.nt of a cost function and the optim.zation is one of the chal.enges of such a concept. Using an Am. rotor system.with an auxil.ary bearing, the new concept of m.del.based m.nitoring is investigated using experim.nts and the optim.zation is discussed in this paper.

Pol.en col.ection is necessary for bee survival.and im.ortant for fl.wering pl.nt reproduction, yet if and how pol.en extraction m.tor routines are m.dified with experience is l.rgel. unknown. Here, we used an autom.ted reward and m.nitoring system.to eval.ate m.dification in a com.on pol.en-extraction routine, fl.ral.sonication. Through a series of l.boratory experim.nts with the bum.l.bee, Bom.us im.atiens, we exam.ned whether variation in sonication frequency and accel.ration is due to instrum.ntal.l.arning based on rewards, a fixed behavioral.response to rewards, and/or a m.chanical.constraint. We first investigated whether bees coul. l.arn to adjust their sonication frequency in response to pol.en rewards given onl. for specified frequency ranges and found no evidenee of instrum.ntal.l.arning. However, we found that absenee versus receipt of a pol.en reward did l.ad to a predictabl. behavioral.resp on se, which depe nded on bee size. Fin al.y, we found som. evide nee of m.chanical.con straints, in that fl.wer m.ss affected sonication accel.ration (but not frequency) through an interaction with bee size. In general. l.rger bees showed m.re fl.xibil.ty in sonication frequency and accel.ration, potential.y refl.cting a size-based constraint on the range over which sm.l.er bees can m.dify frequency and accel.rati on. Overal. our resul.s show that al.hough bees did not displ.y instrum.ntal.l.arning of sonication frequency, their sonication m.tor routine is neverthel.ss fl.xibl..

Frontiers of Structural.and Civil.Engineering 2016年第3期10卷 312-332页

作者： A. SIl.A Y. JIANG l. m.CEDO J. m. CASTRO R. m.NTEIRO N. SIl.ESTRE Departm.nt of Civil.Engineering Faculty of Engineering University of Porto Porto 4099-002 Portugal Istituto Universitario di Studi Superiori di Pavia Pavia 27100 Italy IDm.C LAETA Department of Mechanical Engineering Instituto Superior Tecnico Universidade de Lisboa Lisboa 1649-004 Portugal

The m.in objective of the research presented in this paper is to study the bending behaviour of Concrete Fil.ed Steel.Tube （CFST） col.m.s m.de with Rubberized Concrete （RuC）, and to assess the seism.c perform.nce of m.m.nt-resisting fram.s with these structural.m.m.ers. The paper describes an experim.ntal.cam.aign where a total.of 36 specim.ns were tested, resorting to a novel.testing setup, aim.d at reducing both the preparation tim. and cost of the test specim.ns. Different geom.trical.and m.terial.param.ters were considered, nam.l. cross-section type, cross-section sl.nderness, aggregate repl.cem.nt ratio, axial.l.ad l.vel.and l.teral.l.ading type. The m.m.ers were tested under both m.notonic and cycl.c l.teral.l.ading, with different l.vel. of appl.ed axial.l.ading. The test resul.s show that the bending behaviour of CFST el.m.nts is highl. dependent on the steel.tube properties and that the type of infil. does not have a significant infl.ence on the fl.xural.behaviour of the m.m.er. It is al.o found that Eurocode 4 is conservative in predicting the fl.xural.capacity of the tested specim.ns. Additional.y, it was found that the seism.c design of com.osite m.m.nt- resisting fram.s with CFST col.m.s, according to Eurocode 8, not onl. l.ads to l.ghter design sol.tions but al.o to enhanced seism.c perform.nce in com.arison to steel.fram.s.

Resistance of stored bean varieties to Acanthoscel.des obtectus （Col.optera： Bruchidae）

引用

Insect Science 2008年第4期15卷 317-326页

作者： Edson l.l. Bal.in Fernando m. l.ra Departm.nt of Pl.nt Production-Facul.y of Agronom.c Sciences/Sao Paul. State University Botucatu Sao Paulo State Departm.nt of Pl.nt Protection Faculty of Agranan and Veterinary Sciences / Sao Paulo State University Zip Code 14884-900 Jaboticabal Sao Paulo State Brazil

During bean seed storage, yiel. can be l.st due to infestations of Acanthoscel.des obtectus Say, the bean weevil. The use of resistant varieties has shown prom.sing resul.s in fighting these insects, reducing infestation l.vel. and el.m.nating chem.cal.residues from.the beans. The expression of resistance to A. obtectus in bean varieties is frequentl. attributed to the presence of phytohem.ggl.tinins, protease inhibitors and al.ha-am.l.se, and especial.y to variants of the protein arcel.n, which reduce the l.rval.viabil.ty of these insects. To eval.ate the effect of bean seed storage tim. on the resistance expression of bean varieties to A. obtectus, tests with seeds of three ages （freshl.-harvested, 4-m.nth-ol., and 8-m.nthol.） were conducted in the l.boratory, using four com.ercial.varieties： Carioca Pitoco, Ipa 6, Porril.o 70, Onix; four im.roved varieties containing arcel.n protein： Arc. 1, Arc.2, Arc. 3, Arc.4; and three wil. varieties al.o containing arcel.n protein： ***, Arc.3S, and Arc. 5S. The Arc.5S, ***, and Arc.2 varieties expressed high antibiosis l.vel. against the weevil. Arc.1 and Arc3S expressed the sam. m.chanism. but at l.wer l.vel.. The occurrence of oviposition non-preference was al.o observed in Arc.5S and Arc. 1S. The Arc.3 and Arc. 4 varieties expressed l.w feeding non-preference l.vel. against A. obtectus. The expression of resistance in arcel.n-bearing, wil. or im.roved varieties was affected during the storage of seeds, and was high under som. param.ters but l.w in others. The resul.s showed that addition of chem.cal.resistance factors such as protein arcel.n via genetic breeding m.y be beneficial.in im.roving the perform.nce of bean crops.
