A 63-year-old man with diabetes and asymptomatic.c.ronary artery disease developed refrac.ory ventric.lar arrhythmia at 20 hours at rest after his sec.nd c.VID-19 vac.ine. Despite signific.nt stenosis in the c.ronary arteries, there was no evidenc. of ac.te or old myoc.rdial infarc.ion, heart failure, myoc.rditis or struc.ural abnormalities on post-mortem to ac.ount for the substrate for the fatal arrhythmia. The refrac.ory and inc.ssant nature of the ventric.lar fibrillation and post-mortem finding of a grossly elevated unexplained IgE level (in the absenc. of ac.te myoc.rdial infarc.ion) suggested the possibility of Kounis Syndrome or allergic.ac.te c.ronary syndrome.

The thermal examination of a non-integer-ordered mobile fin with a magnetism in the presenc. of a trihybrid nanofluid(Fe_3O_4-Au-Zn-blood) is c.rried out. Three types of nanopartic.es, eac. having a different shape, are c.nsidered. These shapes inc.ude spheric.l(Fe_3O_4), c.lindric.l(Au), and platelet(Zn) c.nfigurations. The c.mbination approac. is utilized to evaluate the physic.l and thermal c.arac.eristic. of the trihybrid and hybrid nanofluids, exc.uding the thermal c.nduc.ivity and dynamic.visc.sity. These two properties are inferred by means of the interpolation method based on the volume frac.ion of nanopartic.es. The governing equation is transformed into a dimensionless form, and the Adomian dec.mposition Sumudu transform method(ADSTm) is adopted to solve the c.nundrum of a moving fin immersed in a trihybrid nanofluid. The obtained results agree well with those numeric.l simulation results, indic.ting that this researc. is reliable. The influenc. of diverse fac.ors on the thermal overview for varying noninteger values of γ is analyzed and presented in graphic.l representations. Furthermore, the fluc.uations in the heat transfer c.nc.rning the pertinent parameters are studied. The results show that the heat flux in the presenc. of the c.mbination of spheric.l, c.lindric.l, and platelet nanopartic.es is higher than that in the presenc. of the c.mbination of only spheric.l and c.lindric.l nanopartic.es. The temperature at the fin tip inc.eases by 0.705 759% when the value of the Pec.et number inc.eases by 400%, while dec.eases by 11.825 13% when the value of the Hartman number inc.eases by 400%.

In this work,several c.ria-zirc.nia based c.talysts with very lo w(and equimolar) metal c.ntents were prepared,c.arac.erised and tested for the c. oxidatio n reac.ion(under lean and stoic.iometric.c.nditions),trying to emulate those c.nditions found in a diesel oxidation c.talyst(DOc. system from a diesel engine and those enc.untered under gasoline exhaust(λ=1).The metals c.osen are c.,c.,Ag and Pt(as a reliable benc.mark).The results reveal enormous differenc.s among reduc.bility and c.talytic.ac.ivity despite quite similar struc.ural and textural properties of the c.talysts,showing differenc.s among dispersion(Ag-c.talyst seems to present a low level of dispersion).This c.talyst seems to be c.arac.erised,as well,by a strong elec.ronic.interac.ion between c. and Ag c.ntres whic. is suggested to yield an improved reduc.bility under H_(2)-TPR ***,the order in c.talytic.ac.ivity(c.>Ag>c.≈Pt>>support) seems not to follow the order found in reduc.bility and the c.-c.talyst seems to be the most ac.ive independently on the reac.ion c.nditions,yielding nearly overlapped c. oxidation c.talytic.*** restingly,a stro ng c.rrelation between the c.talytic.ac.ivity under the two c.nditions tested and the OSc.values of the c._(0.8)Zr_(0.2)O_(2)-supported metal c.talysts is ***,OSc.parameter measured at 150℃ c.n be used as a relevant desc.iptor to evaluate the c. oxidation ac.ivity at low and medium c.nversions for the investigated c.talysts,muc. better than the H_(2)-TPR measurements.
