A n.w method for the syn.hesis of azo Schiff an.base ligan. in.which the azo an. azomethin. groups are coordin.tion.sites was developed through a Schiff base precursor. The precursor, n.4-methoxyben.yliden.-3-hydroxyphen.lamin. （SB） derived from 3-amin.phen.l was regioselectively coupled with a diazon.um ion.para to the hydroxyl group of the amin. compon.n. of the Schiff base. The para selectivity was con.rolled by the directin. effect of the hydroxyl group. The ligan. an. its n.ckel（Ⅱ） complex were characterized by elemen.al an.lyses, IR an. UV-Vis spectroscopy. The an.lytical an. spectral data supported the mon.n.clear formulation.of the complex with metal to ligan. ratio （M ： L = 1 ： 2） an. suggested a square plan.r geometry for the complex.

Let σ={σi | i ∈ I} be some partition.of the set of all primes P. A set H of subgroups of G is said to be a complete Hall σ-set of G if every member ≠ 1 of H is a Hall σi-subgroup of G, for some i ∈ I, an. H con.ain. exactly on. Hall σi-subgroup of G for every σi ∈σ(G). A subgroup H of G is said to be:σ-permutable or σ-quasin.rmal in.G if G possesses a complete Hall σ-set H such that HAx= AxH for all A ∈ H an. x ∈ G:σ-subn.rmal in.G if there is a subgroup chain.A = A0≤A1≤···≤ At = G such that either Ai-1■Ai or Ai/(Ai-1)Ai is a fin.te σi-group for some σi ∈σ for all i = 1,..., *** Mn.n.1 n. then.Mn.is said to be an.n.maximal subgroup of G. If each n.maximal subgroup of G is σ-subn.rmal(σ-quasin.rmal,respectively) in.G but, in.the case n.> 1, some(n.1)-maximal subgroup is n.t σ-subn.rmal(n.t σ-quasin.rmal,respectively) in.G, we write mσ(G)= n.mσq(G)= n. respectively).In.this paper, we show that the parameters mσ(G) an. mσq(G) make possible to boun. the σ-n.lpoten. len.th lσ(G)(see below the defin.tion. of the terms employed), the ran. r(G) an. the n.mber |π(G)| of all distin.t primes dividin. the order |G| of a fin.te soluble group G. We also give the con.ition. un.er which a fin.te group is σ-soluble or σ-n.lpoten., an. describe the structure of a fin.te soluble group G in.the case when.mσ(G)=|π(G)|. Some kn.wn.results are gen.ralized.

Un.er the effects of electric field an. chemical reaction. the problem of dispersion.of aerosols in.a poorly con.uctin. fluid in.a chan.el is solved an.lytically usin. the mixture theory together with a regular perturbation.techn.que. It is shown.that the aerosols are dispersed relative to a plan. movin. with the mean.speed of atmospheric fluid as well as the mean.speed of agglomeration.of aerosol with a relative diffusion.coefficien., called the Taylor dispersion.coefficien.. This coefficien. is n.merically computed an. the results reveal that it in.reases with an.in.rease in.the electric n.mber, but decreases with in.reasin. porous parameter. The physical explan.tion. for the phen.men. are given.in.this article.

Although positron.scatterin. with in.rt gas atoms has been.studied in.theory as well as in.experimen., there are discrepan.ies. The presen. work reports all the major total cross section. of e＋-n.on.scatterin. at in.iden. en.rgies above ion.zation.threshold, origin.tin. from a complex poten.ial formalism. Elastic an. cumulative in.lastic scatterin.s are treated in.the complex spherical e＋-atom poten.ial. Our total in.lastic cross section.in.ludes positron.um formation.together with ion.zation.an. excitation.chan.els in.n.. Because of the Ps formation.chan.el it is difficult to separate out ion.zation.cross section. from the total in.lastic cross section.. An.approximate method similar to electron.atom scatterin. has been.applied to bifurcate ion.zation.an. cumulative excitation.cross section. at en.rgies from threshold to 2000 eV. Comparison. of presen. results with available data are made. An.importan. outcome of this work is the relative con.ribution.of differen. scatterin. processes, which we have shown.by a bar-chart at the ion.zation.peak.
