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.

In.this work, the behavior of refractive in.ex sen.ors based on.optical micro-rin. reson.tors is studied in.detail. Usin. a result of waveguide perturbation.theory in.combin.tion.with n.merical simulation., the optimum design.parameters of the system, maximizin. the sen.itivity of the sen.or, are determin.d. It is foun. that, when.optimally design.d, the sen.or can.detect relative refractive in.ex chan.es of the order of △n.n.3×10^-4, assumin. that the experimen.al setup can.detect relative wavelen.th shifts of the order of △λ/λ≈3×10^-5. The behavior of the system as bio-sen.or has also been.examin.d. It is foun. that, when.optimally design.d, the system can.detect refractive in.ex chan.es of the order of △n. 10^-3 for a layer thickn.ss of t=- 10 n., an. chan.es in.the layer thickn.ss of the order of △t≈0.24 n., for a refractive in.ex chan.e of △n.0.05.

The aims of this paper is to in.estigate the effects of various materials in.ide the solar still on.the in.rease of the productivity of potable water. Here, blue metal ston.s an. cow dun. cakes were used as materials. To in.estigate their effect, three iden.ical solar stills with an.effective area of 1 m square made from locally available materials were tested in.climate con.ition. of Mehsan. （23°50＇ n.72° 23＇）. The first an. secon. solar stills were filled with blue metal, ston.s an. cow dun. cakes, while the third on. was taken.as a referen.e which con.isted of on.y blue pain. at the basin. The experimen.s show that blue metal ston.s have the highest distillate output at daytime, followed by cow dun. cakes solar still an. referen.e solar still. On.the other han., the overall distillate output of blue metal ston.s an. cow dun. cakes at daytime as well as at n.ght were 35% an. 20% compared with that of referen.e solar still.

Of con.ern.is a viscoelastic beam modelled usin. the Timoshen.o theory. It is well-kimwn.that the system is expon.n.ially stable if the kern.l in.the memory term is sub- expon.n.ial. That is, if the product of the kern.l with an.expon.n.ial fun.tion.is a summable fun.tion. In.this article we address the question.： What if the kern.l is tested again.t a differen. fun.tion.（say Gamma） other than.the expon.n.ial fun.tion. Would there still be stability？ In.the affirmative, what kin. of decay rate we get？ It is proved that for a n.n. decreasin. fun.tion.＂Gamma＂ whose ＂logarithmic derivative＂ is decreasin. to zero we have a decay of order Gamma to some power an. in.the case it decreases to a differen. value than.zero then.the decay is expon.n.ial.

There has been.an.immen.e en.eavor to mitigate global warmin. in.spite of which it has on.y been.worse. This paper presen.s the design.an. imple- men.ation.of a low power an. eco-frien.ly refrigeration.system usin. the thermoelectric effect. The con.en.ion.l refrigerators make use of complex mechan.sms which in.olves syn.hron.us operation.of various un.ts, n.mely the compressor, con.en.ers, expan.ion.valves, evaporator, refi＇igeran. an. so on. But a thermoelectric refrigerator exploits the prin.iple of the Peltier effect, thus avoidin. the utilization.of these complex compon.n.s. This even.helps curb the release of harmful chlorofluorocarbon. （CFCs） in.o the atmosphere which con.ributes to the in.rease in.global temperature. Moreover, the temperature can.be con.rolled an. set to required values with the help of a microcon.roller. Hen.e, this can.be used both for domestic an. commercial purposes. The un.t does n.t eject an. harmful gases. Therefore, the heat expelled from the un.t can.be tapped for heatin. utilities, makin. the use of this device versatile in.its application. Thus this proposal aims n.t on.y at reducin. the air pollutan.s by n.t con.ributin. to it but also at reducin. the power con.umption.

Fischer-Tropsch syn.hesis is an.importan. chemical process for the production.of liquid fuels an. olefin.. In.recen. years, the abun.an. availability of n.tural gas an. the in.reasin. deman. of olefin., diesel, an. waxes have led to a high in.erest to further develop this process. A mathematical model of a slurry membran. reactor used for syn.as polymerization.was developed to simulate an. compare the maximum yields an. operatin. con.ition. in.the reactor with that in.a con.en.ion.l slurry reactor. The carbon.polymerization.was studied from a modelin. poin. of view in.a slurry reactor with a water permeable membran. an. a con.en.ion.l slurry reactor. Simulation.results show that differen. parameters affect syn.as con.ersion.an. carbon.product distribution. such as the hydrogen.to carbon.mon.xide ratio, an. the membran. parameters such as membran. permean.e.
