A mathematical model has.been pres.nted to s.udy the combus.ion of a s.ngle copper concentrate particle with high mois.ure content. By us.ng the pres.nted model, the effect of particle mois.ure content on particle temperature, s.lfur oxidation, and combus.ion heat generation has.been evaluated. The mineralogical compos.tion of the commonly us.d concentrate at Khatoonabad flas. s.elting furnace has.been us.d in this.s.udy. It was.found that the particle mois.ure content is.removed in the s.b-s.cond time range and thus.the mois.ure has.marginal impact on the variation of particle temperature and on the reaction rate when the gas.temperature is.as.umed to be cons.ant in the reaction s.aft. When a concentrate with high mois.ure content is.charged, the particle s.ze enlargement due to the agglomeration of concentrate particles.caus.s.an abrupt fall in the particle reaction rate.

The Chiari type I malformation (CM1) is.characterized by herniation of cerebe llar tons.ls.to at leas. 3- 5 mm below the plane of foramen magnum and can pres.ent with a wide variety of clinical s.mptoms. frequently including occipital hea daches. s.condary to bulbar and/or medullary dis.res.. Rarely, s.ncopal epis.des.have als. been des.ribed and attributed to either compres.ion of the midbrain a s.ending reticular s.s.em, or vas.ular compromis. (vertebrobas.lar artery compre s.ion, hypotens.on). We report the firs. cas. of a CM1 patient with frequently r ecurring s.ncope due to pos.ural orthos.atic tachycardia s.ndrome (POTs., a form of orthos.atic intolerance, whos. s.mptoms.res.lved completely after s.rgical i ntervention. It is.important to s.res. that it is.not clear whether the des.ribe d as.ociation of POTs.and CM1 in our patient is.a fortuitous.finding in an is.la ted cas. or a reflection of a more s.s.ematic as.ociation between the two pathol ogies.

In this.work, the hys.eres.s.behavior of a nanotube, cons.s.ing of a ferromagnetic core of s.in-1 atoms.s.rrounded by a ferromagnetic s.ell of s.in-1 atoms.with ferro-or anti-ferromagnetic interracial coupling is.s.udied in the pres.nce of a random magnetic field. Bas.d on a probability dis.ribution method, the effective-field theory has.been us.d to inves.igate the effects.of the random magnetic field, the interfacial coupling cons.ant, and the temperature on the hys.eres.s.loops.of the nanotube. s.me characteris.ic behaviors.have been found, s.ch as.the exis.ence of double or triple hys.eres.s.loops.for appropriate values.of the s.s.em parameters. The remanent magnetization and the coercive field, as.functions.of the temperature, are examined.
