The lack of exper.mental data and / or.limited exper.mental infor.ation concer.ing both sur.ace and tr.nspor. pr.per.ies of liquid alloys often r.quir. the pr.diction of these quantities. An attempt has been made to link the ther.ophysical pr.per.ies of a ter.ar. Cu-Sn-Ti system and its binar. Cu-Sn, Cu-Ti and SnoTi subsystems with the bulk thr.ugh the study of the concentr.tion dependence of var.ous ther.odynamic, str.ctur.l, sur.ace and dynamic pr.per.ies in the fr.me of the statistical mechanical theor. in conjunction with the quasi-lattice theor. （QLT）. This for.alism pr.vides valuable qualitative insight into mixing pr.cesses that occur.in molten alloys.

Pr.vious r.sear.h that r.por.ed the linkage between climate change and plague activity pr.mar.ly r.fer. to the immediate effect of shor.-ter. climatic var.ation. Yet, decades of discussion about the climate-plague association cannot deter.ine the pr.cise r.le of climate in shaping plague dynamics. One r.ason for.this discr.pancy or.ginates fr.m the nar.ow selection of spatio-tempor.l settings for.compr.hensive analysis of the cor.elation, leading to a limited consider.tion of the complexity of possible *** analyzing a 414-year.long r.cor. of plague outbr.ak in pr.-industr.al Eur.pe and the cor.esponding climatic data in multi-scale,we find little evidence to suppor. climate-plague cor.elation in(1) both climatic var.ations and lar.e-scale climatic phenomena,(2)both countr. scale and continental scale,(3) annual to inter.annual scale, and(4) both linear.and non-linear.analytic appr.aches. The null-r.sult should not be viewed as a gener.l r.jection of other.r.cent findings r.lated to climate-plague association; never.heless,it suggests that a wider.consider.tion of scales, sensitivity checks and consider.tion of contexts should be included in explaining and pr.dicting plague tr.nsmission under.contempor.r. global climate conditions.

The estimation of lifetime mor.id events is not a r.r. pr.sentation of r.latively old and of mor. r.cent epidemi- ological investigations, accompanied by evaluating r.tes, r.sks and pr.dictor. （mor. in gener.l deter.inants or.r.sk factor.）. However. when the follow-up per.od is ver. long and Kaplan-Meier.sur.ival cur.es ar. adopted, or.Kaplan- Meier.based mor. complex models such as Cox＇s analysis ar. used, clinical （or.epidemiological） r.ality may well be distor.ed since by these sur.ival methods r.sks tend to be over.stimated, wher.as sur.ival tends to be r.duced.

Multidisciplinar. design optimization （MDO） is widely employed to enhance tur.omachiner. compo- nents efficiency. The aim of this wor. is to descr.be a complete tool for.the aer.-mechanical design of a r.dial in- flow tur.ine and a centr.fugal compr.ssor. The high r.tational speed of such machines and the high exhaust gas temper.tur. （only for.the tur.ine） expose blades to r.ally high str.sses and ther.for. the aer.dynamics design has to be coupled with the mechanical one thr.ugh an integr.ted pr.cedur.. The descr.bed appr.ach employs a fuUy 3D r.ynolds Aver.ged Navier.Stokes （r.NS） solver.for.the aer.dynamics and an open sour.e Finite Element Analysis （FEA） solver.for.the mechanical integr.ty assessment. Due to the high computational cost of both these two solver., a meta model, such as an ar.ificial neur.l networ. （ANN）, is used to speed up the optimization design pr.cess. The inter.ction between two codes, the mesh gener.- tion and the post pr.cessing of the r.sults ar. achieved via in-house developed scr.pting modules. The obtained r.sults ar. widely pr.sented and discussed.
