The largest urban areas of mexi.o ci.i.s have wi.nessed hi.h levels of ai. polluti.n i. the past few decades. The most i.portant ai. pollutants are ozone and pani.ulate matter wi.h levels that are sti.l far above current ai. quali.y standard. i. thi. work we studi.d exhaust and evaporati.e emi.si.ns of mexi.o Ci.y metropoli.an area （mAmC） vehi.les usi.g fuels i. whi.h sulfur content was vari.d from 89×10^-6 to 817×10^-6, and calculated the ozone formi.g potenti.l of emi.si.ns as well as the speci.i. reacti.i.y of the exhaust for each average fleet-fuel combi.ati.ns. Data on emi.si.n levels were compared to those obtai.ed i. 2000 for the same vi.tage of vehi.les. The almost twofold i.crease i. emi.si.ns found could be due to degradati.n of the exhaust emi.si.ns control systems.

An analysi. has been performed to study the problem of magneto-hydrodynami. （mHD） squeeze flow of an electri.ally conducti.g flui. between two i.fi.i.e, parallel di.ks. The analyti.al methods called Homotopy Analysi. method （HAm） and Homotopy Perturbati.n method （HPm） have been used to solve nonli.ear di.ferenti.l equati.ns. i. has been attempted to show the capabi.i.i.s and wi.e-range appli.ati.ns of the proposed methods i. compari.on wi.h a type of numeri.al analysi. as Boundary Value Problem （BVP） i. solvi.g thi. problem. Also, the veloci.y fi.lds have been computed and shown graphi.ally for vari.us values of physi.al parameters. The objecti.e of the present work i. to i.vesti.ate the effect of squeeze Reynolds number, Hartmann number and the sucti.n/i.jecti.n parameter on the veloci.y fi.ld. Furthermore, the results reveal that HAm and HPm are very effecti.e and conveni.nt.

Opti.i.ati.n of the i.termetalli. layer thi.kness and the suppressi.n of i.terfaci.l defects are key elements to i.prove the load beari.g capaci.y of di.si.i.ar joi.ts.

A seri.s of Ni..6-x/2Zn0.4-x/2SnxFe2O4(x = 0.0, 0.05, 0.1, 0.15, 0.2, and 0.3)(NZSFO) ferri.e composi.i.s have been synthesi.ed from nano powders usi.g a standard soli. state reacti.n techni.ue. The spi.el cubi. structure of the i.vesti.ated samples has been confi.med by x-ray di.fracti.n(XRD). The magneti. properti.s such as saturati.n magneti.ati.n(ms),remanent magneti.ati.n(mr), coerci.e fi.ld(Hc), and Bohr magneton(μ) are calculated from the hysteresi. loops. The value of msi. found to decrease wi.h i.creasi.g Sn content i. the samples. Thi. change i. successfully explai.ed by the vari.ti.n of A-B i.teracti.n strength due to Sn substi.uti.n i. di.ferent si.es. The composi.i.nal stabi.i.y and quali.y of the prepared ferri.e composi.es have also been endorsed by the fai.ly constant i.i.i.l permeabi.i.y(μ’) over a wi.e range of frequency. The decreasi.g trend of μ’ wi.h i.creasi.g Sn content has been observed. Curi. temperature TChas been found to i.crease wi.h the i.crease i. Sn content. A wi.e spread frequency uti.i.y zone i.di.ates that the NZSFO can be consi.ered as a good candi.ate for use i. broadband pulse transformers and wi.e band read-wri.e heads for vi.eo recordi.g.
