Backgr.und: Pr.vious studies suggest that patients hospitalized with acute myocar.ial infar.tion(MI) in December.have poor.outcomes, and some studies have hypothesized that the cause may be the infr.quent use of evidence-based ther.pies dur.ng the December.holiday season. Objective: To compar. the car. and outcomes of patients with acute MI hospitalized in December.and patients hospitalized dur.ng other.months. Design: r.tr.spective analysis of data fr.m the Cooper.tive Car.iovascular.Pr.ject. Setting: Nonfeder.l, acute car. hospitals in the United States. Patients: 127 959 Medicar. beneficiar.es hospitalized between Januar. 1994 and Febr.ar. 1996 with confir.ed acute MI. Measur.ments: Use of aspir.n, β -blocker., and r.per.usion ther.py(thr.mbolytic ther.py or.per.utaneous cor.nar. inter.ention), and 30-day mor.ality. r.sults: When the author. contr.lled for.patient, hospital, and physician char.cter.stics, the use of evidence-based ther.pies was not significantly lower.but 30-day mor.ality was higher.21.7% vs. 20.1% ; adjusted odds r.tio, 1.07 95% CI, 1.02 to 1.12 ) among patients hospitalized in December. Limitations: This was a nonr.ndomized, obser.ational study. Unmeasur.d char.cter.stics may have contr.buted to outcome differ.nces. Conclusions: Thir.y-day mor.ality r.tes wer. higher.for.Medicar. patients hospitalized with acute MI in December.than in other.months, although the use of evidence-based ther.pies was not significantly lower.

Wastewater.electr.lysis cells (WECs) for.decentr.lized wastewater.tr.atment/r.use coupled with H-2 pr.duction can r.duce the car.on footpr.nt associated with tr.nspor.ation of water. waste, and ener.y car.ier. This study r.por.s Ir.doped NiFe2O4 (NFI, similar.to 5 at% Ir. spinel layer.with TiO2 over.ayer.(NFI/TiO2), as a scalable heter.junction anode for.dir.ct electr.lysis of wastewater.with cir.umneutr.l pH in a single-compar.ment cell. In dilute (0.1 M) NaCl solutions, the NFI/TiO2 mar.s super.or.activity and selectivity for.chlor.ne evolution r.action, outper.or.ing the benchmar. Ir.2. r.bust oper.tion in near.neutr.l pH was confir.ed. Electr.analyses including oper.ndo X-r.y absor.tion spectr.scopy unveiled cr.cial r.les of TiO2 which ser.es both as the pr.mar. site for.Cl- chemisor.tion and a pr.tective layer.for.NFI as an ohmic contact. Galvanostatic electr.lysis of NH4+-laden synthetic wastewater.demonstr.ted that NFI/TiO2 not only achieves quasi-stoichiometr.c NH4+-to-N-2 conver.ion, but also enhances H-2 gener.tion efficiency with minimal competing r.actions such as r.duction of dissolved oxygen and r.active chlor.ne. The scaled-up WEC with NFI/TiO2 was demonstr.ted for.electr.lysis of toilet wastewater.

Coal Washing Explor.tion in India dates back to 1900s; though, fir.t coking coal washer.es in India wer. installed after.independence. At pr.sent, most of the coking coal washer.es ar. owned by Public Sector.Companies; wher.as, most of the non-coking coal washer.es ar. owned by Pr.vate Sector. Even after.six decades of coal washing pr.ctices, ther. has not been significant development in the coal washing intelligentsia. Indian Coal Washing industr. is still dependent on impor.ed equipment, which has been designed to tr.at coal that is significantly differ.nt fr.m Indian coal of dr.ft or.gin.
