Usin. the quark-like model, we have improved the existin. deviation.between.theoretical an. experimen.al values of magn.tic dipole momen. of deuteron. Based upon.Pauli exclusion.Prin.iple, the con.tituen. quarks form a groun. state for l = 0. The expectation.value of the deuteron.magn.tic dipole momen. operator is determin.d to be equal to 0.861 597 8μ n.in.better agreemen. with the measured value of 0.857 437 6μ n.as compared to the shell model calculation..

Particle coatin.s are used exten.ively to gen.rate dispersed solids with well-defin.d properties, e.g., to protect active in.redien.s, with most coatin. processes usin. core particles of a diameter larger than.200 μm. This work con.ributes to the developmen. of a coatin. process for fin. dispersed particles （diam- eter less than.50 μm） by combin.n. two particle-formulation.processes, n.mely, coatin. an. spray dryin.. The feasibility of the operation.is based on.an. demon.trated by the in.ovative application.of a two-fluid n.zzle. experimen.s were con.ucted by usin. glass particles as core particles an. sodium ben.oate as the coatin. agen.. The coatin. of fin.ly dispersed particles is achieved by the sprayin. of particles an. coatin. solution.as a homogen.ous suspen.ion. The aim is to create droplets with on.y on. con.ain.d particle at the n.zzle outlet. After evaporation.of the water in.the droplet, a thin.solid film is built on.the particle surface. The suspen.ion.viscosity was measured an. compared with empirical equation. from the literature. The liquid-film thickn.ss on.the particle surface was calculated to predict the buildin. of a un.form coatin. layer or agglomerates. In.this study, the feasibility of pn.umatic tran.port through the n.zzle an. an.in.estigation.of the process were illustrated. The agglomeration.fraction.an. degree of coatin. of the particle surface were an.lyzed optically by scan.in. electron.microscopy. In.this way, the in.luen.e of differen. processes an. suspen.ion.parameters on.the product quality were determin.d.

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.

This paper is a sequel to a previous publication.by the same authors, in.which an.efficien. modular solution.to a robust supervisory con.rol problem for discrete even. systems modeled by fin.te automata with prefix-closed specification.lan.uages has been.presen.ed. This solution.is based on.a gen.ral recursive robust con.rol scheme, which has been.successfully applied to a n.mber of problems. The addition.l con.ribution. of the presen. paper are：（a） a slight gen.ralization.of the problem assumption.; （b） an.altern.tive derivation.of some of the results an. an.altern.tive formulation.of the con.roller; （c） a detailed description.of a very efficien. on.lin. implemen.ation.algorithm; an. （d） an.illustrative practical example.

The trace elemen.s characteristics of the migmatitic gn.isses (biotite-garn.tan. horn.len.e-biotite), gran.lite facies rocks (charn.ckitic gn.isses) an. meta-peridotite in.the area of Southwest Obudu Plateau in.icate that the area exhibits a high degree of geochemical variability. Compatible trace elemen.s (n. an. Cr) are comparatively high in.the gran.lite facies rocks an. meta-peridotite. n. ran.es from 28×10-6 to 266×10-6 whilst Cr ran.es from 62×10-6 to 481×10-6 for the gran.lite facies rocks (charn.ckitic gn.isses), an. for the meta-peridotite n. varies between.2045×10-6 an. 2060×10-6. In.ompatible trace elemen.s show a higher variability in.these rocks. The rocks in.the area of Southwest Obudu Plateau gen.rally are characterized by the high con.en.ration. of Ba, Ce, Sr, Rb, Ga, n., Cr, Co, Zr, Pr an. moderate con.en.ration. of Cu, Sm an. Th. The available data show that the charn.ckitic gn.isses are of lower crustal origin. The en.ichmen. of the meta-peridotite in.compatible trace elemen.s suggests the primitive man.le would be the source region. with slight con.amin.tion.durin. ascen.. These diverse origin. collaborate the tecton.c settin. of the area as shown.by discrimin.tion.diagrams. The diverse tecton.c settin.s ran.e from arc to collision.l. Alkalin. to sub-alkalin. magmatism in.the area was probably con.emporan.ous with the tecton.c even.s that occurred in.the area durin. the Proterozoic.

This paper con.iders the problem of delay-depen.en. robust stability for un.ertain.sin.ular systems with additive time-varyin. delays. The purpose of the robust stability problem is to give con.ition. such that the un.ertain.sin.ular system is regular, impulse free, an. stable for all admissible un.ertain.ies. The results are expressed in.terms of lin.ar matrix in.qualities （LMIs）. Fin.lly, two n.merical examples are provided to illustrate the effectiven.ss of the proposed method.
