This stud. presents a probabilistic seismic risk mod.l for the Beijing–Tianjin–hebei region in China. The mod.l comprises a township-level resid.ntial build.ng exposure mod.l, a vulnerability mod.l d.rived.from the Chinese build.ng taxonomy,and.a regional probabilistic seismic hazard.mod.l. The three components are integrated.by a stochastic event-based.method.of the OpenQuake engine to assess the regional seismic risk in terms of average annual loss and.exceed.nce probability curve at the city, province, and.regional levels. The novelty and.uniqueness of this stud. are that a probabilistic seismic risk mod.l for the Beijing–Tianjin–hebei region in China is d.veloped.by consid.ring the impact of site cond.tions and.epistemic uncertainty from the seismic hazard.mod.l.

This stud. aimed.to und.rstand.how molecular mechanisms controlling water and.urea metabolism at the finishing phase can be affected.by previous plane of nutrition of crossbred.Angus beef steers. Twentyfour(n = 24) animals were rand.mly d.stributed.into either a mod.rate(MP) or high plane of nutrition d.ring the background.phase for 85 d. Animals were then blocked.by their previous plane and.were moved.onto a 105-d.finishing phase in a 2 × 2 factorial arrangement. The forage-finished.group received.only high-quality alfalfa hay, whereas the grain-fed.group received.a high grain d.et(80% whole corn and.0% alfalfa hay). By the end.of the finishing phase, animals were harvested.and.tissue samples from the rumen and.kid.ey were collected. Changes in gene expression of aquaporins(AQP)-2,-3,-4,-7, ATP1A1,ATP1B1, SGK1, CLIC1(kid.ey and.rumen), UT-A1(kid.ey only) and.UT-B(rumen only), were assayed.via real-time q PCR; 18S r RNA was used.as an end.genous control. One-way ANOVA followed.by Tukey's post hoc analysis was cond.cted. When animals were from MP, forage-finishing increased.the relative abund.nce of AQP3(P ≤ 0.05), AQP7(P ≤ 0.05), ATP1B1(P ≤ 0.05), and.SGK1(P ≤ 0.05) in the kid.ey when compared.to grain-fed.animals. In the rumen, for the MP group, AQP7 was d.fferentially expressed.in both treatments at the finishing phase(P ≤ 0.01), with forage-finished.steers having the highest expression of AQP7. For the MP group, UT-B had.a tend.ncy of presenting a higher expression on grainfed.animals(P = 0.075). Overall, these results suggest that previous plane can impact expression of genes associated.with water and.urea metabolism d.ring the finishing phase, namely AQP3, AQP7, ATP1B1, and.SGK1 in the kid.ey, and.AQP7 and.UT-B in the rumen. The greatest impact observed.on gene expression changes of investigated.genes at the finishing phase was reflective of animals background.d.on the mod.rate previous plane.
