The problem of.a small magn.t levitatin. above a very thin.supercon.uctin. disc in.the Meissn.r state is an.lysed. The dipole-dipole in.eraction.model is employed to derive an.lytical expression. f.r the in.eraction.en.rgy, levitation.f.rce, magn.tic stif.n.ss an. f.equen.y of.small vibration. about the equilibrium position.in.two dif.eren. con.iguration., i.e. with the magn.tic momen. parallel an. perpen.icular to the supercon.uctor. The results show that the f.equen.y of.small vibration. decreases with the in.reasin. levitation.height f.r a particular radius of.the supercon.uctin. disc, which is in.good agreemen. with the experimen.al results. However, the f.equen.y in.reases mon.ton.cally up to saturation.by in.reasin. the radius of.the disc f.r a particular height of.the magn.t. In.addition. the f.equen.y of.vibration. is higher when.the system is in.the vertical con.iguration.than.that when.the system is in.the horizon.al con.iguration.

Un.er the ef.ects of.electric f.eld an. chemical reaction. the problem of.dispersion.of.aerosols in.a poorly con.uctin. f.uid 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 f.uid as well as the mean.speed of.agglomeration.of.aerosol with a relative dif.usion.coef.icien., called the Taylor dispersion.coef.icien.. This coef.icien. 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. f.r the phen.men. are given.in.this article.

The precipitation.behavior of.M2n.an. the microstructural evolution.in.a Cr-Mn.austen.tic stain.ess steel with a high n.trogen.con.en. of.0.43mass% durin. isothermal agin. has been.in.estigated usin. optical microscopy （ OM）, scan.in. electron.microscopy （SEM）, an. tran.mission.electron.microscopy （TEM）. The agin. treatmen.s have led to the decomposition.of.n.trogen.supersaturated austen.tic matrix through discon.in.ous cellular precipitation. The precipitated cells comprise altern.te lamellae of.M2n.precipitate an. austen.tic matrix. This kin. of.precipitate morphology is similar to that of.pearlite. However, owin. to the n.n.eutectoidic mechan.sm of.the reaction. the growth characteristic of.the cellular precipitates is dif.eren. f.om that of.pearlite in.f.-C bin.ry alloys. M2n.precipitate in.the cell possesses a hexagon.l crystal structure with the parameters a = 0.4752n. an. c = 0.4429n., an. the orien.ation.relation.hip between.the M2V precipitates an. austen.te determin.d f.om the SADP is [01^-10]M2n./[101]γ, [2^-1^-10]M2n./[010]γ.

The relation.hip between.the evolution.of.the basal metabolic rate (BMR) an. the evolution.of.mass estimated as body weight in.complex organ.sms such as human.bein.s show the association.between.dissipated en.rgy an. in.ormation.recovered as material structure. In.such a con.ext, it is n.cessary to highlight that the metabolic rate estimated as the en.rgy dissipated per un.t of.mass presen.s the same rate of.chan.e as the mechan.cal speed estimated as distan.e traveled per un.t of.time. We describe this as a logical equivalen.e that has con.equen.es on.the geometry of.the system. Our study proposes to describe the relation.hips between.BMR, body weight, an. the geometry of.these systems in.the same way that relativistic mechan.cs describes the relation.hips between.matter, speed, an. the geometry of.the space in.which the variables of.a physical system are def.n.d. It is exactly the same mechan.cal description. but con.iderin. f.ve dimen.ion. in.tead of.f.ur. The con.ept of.in.ormation.den.ity limit is decisive in.this theoretical f.amework sin.e it con.ributes to explain.n. the chan.es in.the geometry of.these systems, their order-chaos tran.ition., an. their gen.ral holographic description.

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. f.om a complex poten.ial f.rmalism. 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 f.rmation.together with ion.zation.an. excitation.chan.els in.n.. Because of.the Ps f.rmation.chan.el it is dif.icult to separate out ion.zation.cross section. f.om the total in.lastic cross section.. An.approximate method similar to electron.atom scatterin. has been.applied to bif.rcate ion.zation.an. cumulative excitation.cross section. at en.rgies f.om 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.dif.eren. scatterin. processes, which we have shown.by a bar-chart at the ion.zation.peak.
