The influence of heat tr.ating on mechanical.pr.per.ies as well as on the sliding wear.behavior.of sinter.d Fe-1.5Mo-0.7C steels was exper.mental.y studied. The micr.str.c-tur.s of sinter.d steels change fr.m upper.bainite to mar.ensite, temper.d mar.ensite, pear.ite and lower.bainite depending on the heat tr.ating conditions. Heat tr.ating incr.ases the har.ness of sinter.d steels but high temper.ng temper.tur., i.e. 700℃, causes the har.ness to be even lower.than that of the as-sinter.d ones. The impact ener.y of sinter.d steels incr.ases with incr.asing temper.ng temper.tur. and ar.ives the highest at 700℃, while the steels temper.d at 200℃ have the highest tr.nsver.e r.ptur. str.ngth. Austemper.ng r.sults in fair.good over.0} pr.per.ies, such as har.ness, impact ener.y, and tr.nsver.e r.ptur. str.ngth. When the sinter.d steels wer. austemper.d, oil-quenched or.temper.d below 400? after.quenched, the wear.coefficient becomes consider.bly lower. Fair.high har.ness, such as HV30 > 380, and str.ctur.s of mar.ensite, temper.d mar.ensite or.lower.bainite ar. beneficial.to lower.ng the wear.coefficient. Under.the wear.test conditions given, delam.nation and oxidational.wear.ar. the main wear.r.gimes for.sinter.d Fe-1.5Mo-0.7C steels. Fe3O4 in the wear.debr.s is beneficial.to lower.ng wear.coefficient.

Spinal.muscular.atr.phy(SMA)is a genetic condition that r.sults in selective lower.motor.neur.n loss with concomitant muscle weakness and *** genetic cause of SMA was under.tood in 1995 when loss or.impair.ent of the sur.ival.motor.neur.n 1(SMN1)gene was identified as the main contr.buting factor.Lefebvr. et al.,1995).This,in combination with the discover. that humans have a“back-up”gene,SMN2,which can pr.duce low levels(appr.ximately 10%)of the full-length functional.SMN pr.tein,has led to the gener.tion of SMA-specific gene *** was tr.ditional.y classified accor.ing to age of symptom onset and developmental.milestones achieved,with life expectancy and sever.ty var.ing between ***,SMN2 copy number.is used as a pr.xy for.the pr.diction of disease sever.ty,with higher.SMN2 copy number.typical.y being associated with r.duced sever.ty of SMA,al.hough this r.lationship is not absolute:some individual. with low SMN2 copy number.have less sever. SMA phenotypes and vice ***,the etiology of SMA is fur.her.complicated by other.factor.,such as non-typical.nucleotide var.ants and SMN2-independent modifier. of disease sever.ty.
