Context: Early mechanical revascularization in p.tients with acute myocard.al infarction(AMI) comp.icated.by card.ogenic shock is a therap.utic strategy that red.ces mortality. It has been a class I recommend.tion in guid.lines from the American College of Card.ology and.the American Heart Association since 1999 for p.tients younger than 75 years. However, little is known about imp.ementation of these guid.lines in p.actice. Objectives: To assess trend. in early revascularization and.mortality for p.tients with card.ogenic shock comp.icating AMI and.to d.termine whether the national guid.lines affect revascularization rates. d.sign, Setting, and.p.tients: p.osp.ctive, observational stud. of 293 633 p.tients with ST-elevation myocard.al infarction(25 311 8.6% had.card.ogenic shock; 7356 29% had.card.ogenic shock at hosp.tal p.esentation) enrolled.in the National Registry of Myocard.al Infarction(NRMI) from January 1995 to May 2004 at 775 US hosp.tals with revascularization cap.bility(d.fined.as the cap.bility to p.rform card.ac catheterization, p.rcutaneous coronary intervention p.I , and.op.n-heart surgery). Main Outcome Measures: Management p.tterns and.in-hosp.tal mortality rates. Results: There was an increase in p.imary p.I rates from 27.4% to 54.4% (p. .001) in hosp.tals with revascularization cap.bility that p.ralleled.the change in p.I for ST-elevation myocard.al infarction. There was no significant change in rates of immed.ate coronary artery byp.ss graft surgery(from 2.1% to 3.2% ). p.op.nsity-ad.usted.multivariable analyses d.monstrated.that p.imary p.I was associated.with a d.creased.od.s of d.ath d.ring hosp.talization(od.s ratio, 0.46; 95% confid.nce interval, 0.40-0.53).

The p.ominent linear d.ke rid.es outcrop.ed.in the Narmad.-Tap. d.kes’ swarm rep.esent an intrusion in the d.ccan Trap.. Und.rstand.ng the relationship.among the und.rlying geological structures, the strike of the d.kes, and.the channel p.tterns is essential. d.kes act as obstructions to stream flow, causing d.versions, and.their geometry and.p.tterns significantly imp.ct the rivers and.streams that d.ain and.cross the d.ke swarm zone. For this stud., Google Earth images, LISS III images, and.Cartosat d.M were used.to d.lineate the Shivan basin and.extract d.ke features. The Shivan River basin is a sixth-ord.r d.ainage system that reflects sup.rimp.sed.d.ainage systems within the Tap. d.ke swarm zone. About 65% (169 km2) of its area is controlled.by d.ke orientation. The d.ke rid.es align p.ed.minantly in an East-West (E-W) d.rection, a p.ttern mainly followed.by lower-ord.r streams, which have d.velop.d.an insequent, transverse d.ainage network within the d.ke swarm zone. In the lower p.rts of the Shivan basin, where the number of d.kes d.creases, the d.ainage network follows the general slop. and.is oriented.in a North-South d.rection. The Shivan River and.its tributaries have p.rtially ad.usted.to the d.ke orientation, resulting in a transverse d.ainage p.ttern in areas characterized.by p.rallel d.ke rid.es.

In ad.ition to their value as cereal grains, wheat (Triticum aestivum L.) and.triticale (× Triticosecale Wittmack) are imp.rtant cool-season annual forages and.cover crop.. Yearling steer (Bos taurus) p.rformance was comp.red.in the sp.ing following autumn establishment as for age cover crop. after soybean [Glycine max (L.) Merr.] grain harvest. Rep.icated.p.stures (0.4 ha) were no-till seed.d.in three consecutive years into soybean stubble in autumn, fertilized. and.grazed.the following sp.ing near Ithaca, NE, USA. Each p.sture (n = 3) was continuously stocked.in sp.ing with four yearling steers (380 ± 38 kg) for 17, 32, and.28 d.in 2005, 2006, and.2007, resp.ctively. In 2005, average d.ily gain (Ad.) for steers grazing triticale exceed.d.the Ad. for wheat by 0.31 kghd.sup.-1p.d.sup.-1p.. In 2006, wheat Ad. exceed.d.that for triticale by 0.12 kghd.sup.-1p.d.sup.-1p.. In 2007, steers grazing wheat lost weight, while steers grazing triticale gained.0.20 kghd.sup.-1p.d.sup.-1p.. Based.on the 3-year average animal gains valued.at $1.32 kgp.-1p., mean net return ($ hap.-1p. yrp.-1p.) was $62.15 for triticale and.$22.55 for wheat. Since these grazed.cover crop. p.ovid. ecosystem services in ad.ition to forage, grazing could.be viewed.as a mechanism for recovering costs and.ad.s ad.itional value to the system.

p.lymetallic layered.d.uble hyd.oxid.s are p.omising cost-effective catalysts for the oxygen evolution reaction(OER) d.e to their versatile anionic and.cationic tunability. Nevertheless, several challenges p.rsist, notably, issues related.to low electrical cond.ctivity, p.or catalytic activity, and.stability, esp.cially at high current d.nsity. Herein, we rep.rt the d.sign of Ce-and.Lad.p.d.Co Ni Fe-layered.d.uble hyd.oxid.(Ce La Co Ni Fe-Ld.) nanosheets through a facile and.scalable in situ self-assembly strategy that d.sp.ays enhanced.OER activity. Exp.rimental and.theoretical investigations p.ovid. insights into the imp.ct of Ceand.La-d.p.ng by comp.ring Ce Co Ni Fe-Ld., La Co Ni Fe-Ld., and.p.istine Co Ni Fe-Ld., all synthesized.using the same method.logy. These results reveal that d.p.ng Ce^(3+)and.La^(3+)into Co Ni Fe-Ld. substantially imp.oves its electronic structure,resulting in enhanced.cond.ctivity, more oxygen vacancies(Vo), electron interaction, and.active site formation. Consequently,significantly red.ced.overp.tentials of 175, 314, and.424 m V at 10, 100, and.500 m A cm^(-2), resp.ctively, and.a highly stable current d.nsity of 120 h in 1 M KOH were achieved. Notably, these p.rformance metrics surp.ss those of unmod.fied.Ld.s and.are comp.titive with many lanthanid.-d.p.d.transition metal-based.Ld. electrocatalysts, as well as noble metal catalysts like ruthenium catalysts. This work rep.esents a p.oneering effort in d.p.ng Ce^(3+)and.La^(3+)ions into a functional Co Ni Fe-based.electrocatalyst, offering insp.ring OER p.rformance and.scalability p.tential.
