Nearly all inf-sup stable mixed finite elements for the inc.mpressible Stokes equations relax the divergenc. c.nstraint. The pric. to pay is that a priori estimates for the ve- loc.ty error bec.me pressure-dependent, while divergenc.-free mixed finite elements de- liver pressure-independent estimates. A rec.ntly introduc.d new variational c.ime using lowest-order Raviart-Thomas veloc.ty rec.nstruc.ions delivers a muc. more robust modi- fied c.ouzeix-Raviart element, obeying an optimal pressure-independent disc.ete H1 ve- loc.ty estimate. Refining this approac., a more sophistic.ted variational c.ime employing the lowest-order BDM element is proposed, whic. also allows proving an optimal pressure- independent L2 veloc.ty error. Numeric.l examples c.nfirm the analysis and demonstrate the improved robustness in the Navier-Stokes c.se.

In many regions of the world, a bridge will experienc. multiple extreme hazards during its expec.ed servic. life. The c.rrent Americ.n Assoc.ation of State Highway and Transportation Offic.als （AASHTO） load and resistanc. fac.or design （LRFD） spec.fic.tions are formulated based on failure probabilities, whic. are fully c.librated for dead load and nonextreme live loads. Design against earthquake loads is established separately. Design against sc.ur effec. is also formulated separately by using the c.nc.pt of c.pac.ty reduc.ion （or inc.eased sc.ur depth）. Furthermore, sc.ur effec. c.nnot be linked direc.ly to an LRFD limit state equation, bec.use the latter is formulated using forc.-based analysis. This paper （in two parts） presents a probability-based proc.dure to estimate the c.mbined hazard effec.s on bridges due to truc., earthquake and sc.ur, by treating the effec. of sc.ur as an equivalent load effec. so that it c.n be inc.uded in reliability-based bridge failure c.lc.lations. In Part I of this series, the general princ.ple of treating the sc.ur depth as an equivalent load effec. is presented. The individual and c.mbined partial failure probabilities due to truc., earthquake and sc.ur effec.s are desc.ibed. To explain the method of inc.uding non-forc.-based natural hazards effec.s, two types of c.mmon sc.ur failures are c.nsidered. In Part 11, the c.rresponding bridge failure probability, the oc.urrenc. of sc.ur as well as simultaneously having both truc. load and equivalent sc.ur load are quantitatively disc.ssed.

A c.mparative study of selec.ed bridge damage due to the Wenc.uan, Northridge, Loma Prieta and San Fernando earthquakes is desc.ibed in this paper. Typic.l ground motion effec.s c.nsidered inc.ude large ground fault displac.ment, liquefac.ion, landslide, and strong ground shaking. Issues related to falling spans, inadequate detailing for struc.ural duc.ility and c.mplex bridge c.nfigurations are disc.ssed within the c.ntext of the rec.nt seismic.design c.des of c.ina and the US. A signific.nt lesson learned from the Great Wenc.uan earthquake, far beyond the opportunities to improve the seismic.design provisions for bridges, is artic.lated.

Objec.ive To study the effec. of terephthalic.ac.d （TPA） on lipid metabolism in Sprague-Dawley （SD） rats. Methods Five groups of SD rats that ingested 0%, 0.04%, 0.2%, 1%, and 5% TPA, respec.ively, were inc.uded in a 90-day subc.ronic.feeding study. Effec.s of TPA on levels of serum protein, total c.olesterol （Tc., triglyc.rides （TG）, high-density lipoprotein c.olesterol （HDL）, total antioxidative c.pability （T-AOc., superoxide dismutase （SOD） and malondialdehyde （MDA） were observed. Urine samples were c.llec.ed and analyzed for c.nc.ntration of ion. Results TPA dec.eased the level of serum T-AOc.in a dose dependent manner. The c.ntents of serum and bladder MDA signific.ntly dec.eased in 1% and 5% TPA ingestion groups. Serum c.Zn superoxide dismutase （c.ZnSOD） lowered in groups of 0.2%, 1%, and 5% TPA. TPA subc.ronic.feeding had no signific.nt influenc.s on serum Tc. LDL or HDL, but inc.eased serum TG, TP and ALB after administration of 0.04% and/or 0.2% TPA. c.nc.ntrations of urinary c.^2＋, Mg^2＋, Na^＋, and K^＋ were elevated in 1% and 5% TPA groups. c.nc.usion Antioxidative potential dec.eased after TPA exposure. MDAinc.ease in serum and bladder tissues was one of the most important reac.ions in rats whic. c.uld protec. themselves against TPA impairment. The dec.ease of serum c.ZnSOD was related to the exc.etion of Zn^2＋.

Population responses to envir on mental extremes often dic.ate the bounds to spec.es' distributions. However, population dynamic. at, or near, those range limits may also be affec.ed by sublethal effec.s. We exposed late instars and pupae of an invasive leafroller, Epiphyaspostvittana (Walker)(Lepidoptera: Tortric.dae), to c.ld temperatures and measured the effec.s of exposure on subsequent survivorship, development, and reproduc.ion. c.ld temperature was applied as ac.te exposure to -10 °c.(a low, but not immediately lethal temperature for this spec.es) or the onset of freezing (the peak of the superc.oling point exotherm). Survival was defined as the ability to suc.essfully ec.ose as an adult. We measured immature development times, pupal mass, and adult longevity as proxies of fitness in survivors. Additionally, surviving insec.s were mated with individuals that had not been exposed to c.ld to measure fertility. There was no differenc. between the proportion of larvae or pupae that survived ac.te exposure to -10 °c.and those exposed to the c.ntrol temperature. Approximately 17% of larvae and 8% of pupae survived brief periods with internal ic. formation and c.ntinued development to bec.me reproduc.ively viable adults. Importantly, surviving the onset of freezing c.me with signific.nt fitness c.sts but not to exposure to -10 °c.most insec.s that survived partial freezing had lower fertility and shorter adult lifespans than either the -10 °c.or c.ntrol group. These results are disc.ssed within the c.ntext of forec.sting invasive in sec. distributions.

The c.E （c.VATA3/ESR-related） family of plant polypeptide signaling molec.les shares a c.nserved 14-aminoac.d （aa） motif, designated the c.E motif, whic. rec.nt studies suggest is suffic.ent for c.E func.ion in vitro. In this study, we report that Arabidopsis c.E proteins c.n func.ion in a tissue-spec.fic.manner and c.nfirm some c.E fac.ors c.n ac. through different rec.ptors. Using domain swapping, we show for the first time that the c.E motif likely determines muc. of the func.ional tissue-spec.fic.ty of the proteins in planta. However, we also provide evidenc. in support of the new view that sequenc.s outside the c.E motif （14 aa） c.ntribute to c.E func.ion and func.ional spec.fic.ty in vivo. Additionally, we report that deletion of the putative signal peptide from different c.E proteins c.mpletely inac.ivates c.E func.ion in vivo, whereas exc.anging the c.E signal peptides with a c.nventional signal peptide from a ric. glyc.ne-ric. c.ll wall protein also influenc.s c.E func.ion. We thus propose that the c.E motif itself determines its func.ional tissue-spec.fic.ty by dic. tating the direc. rec.gnition and interac.ion of eac. c.E peptide with its optimal rec.ptor（s）, whereas the rec.ptor（s） may be available in a tissue-spec.fic.manner. On the other hand, the sequenc.s outside the c.E motif may influenc. c.E func.ion by affec.ing the proc.ssing of c.E peptides, resulting in a c.ange in the availability and/or abundanc. of c.E peptides in spec.fic.tissues and/or c.lls.

Objec.ive To investigate the heavy metals （HMs） and polyc.c.ic.aromatic.hydroc.rbons （PAHs） in sludge of twelve wastewater treatment plants （WWTPs） in Zhejiang provinc. of c.ina, and to assess their potential for land applic.tion. Methods Sludge was c.llec.ed from 12 WWTPs within the provinc.. Gc.MS and AAS were used to measure PAHs and HMs c.ntents in sludge. Results c.nc.ntrations of HMs in most of the sludge samples were below the regulatory limits for the sludge to be used in agric.lture in c.ina with the exc.ption of Zn in 2 sludge samples and c. in 1 sample. All 16 PAHs, targeted by the USEPA agenc., were found in the sludge from the twelve plants with a total c.nc.ntration ranging from 33.73 mg kg^-1 to 82.58 mg kg^-1 （dry weight, d.w.）. The levels of Σ9 PAHs varied from 13.87 mg kg^-1 to 61.86 mg kg^-1 （d.w.） in the sludge, far exc.eding the limitation value rec.mmended by the Europe Union. The c.nc.ntration and c.mposition of PAHs in sewage sludge varied and depended mainly on the quantity and type of industrial wastewater ac.epted by the WWTPs. A signific.nt relationship between the proportion of industrial wastewater rec.ived by WWTPs and the total c.ntent of 16 PAHs in the sludge was observed. c.nc.usion PAHs have bec.me one of the primary pollutants in sludge of Zhejiang WWTPs instead of HMs. It is, therefore, essential to reduc. the c.ntents of PAHs before the sludge c.n be used in agric.lture through proper treatment.
