The effect of magnetic field on torsional waves propagating in non-homogeneous viscoelastic cylindrically aeolotropic material is discussed. The elastic constants and non-homogeneity in viscoelastic medium in terms of density and elastic constant is taken. The frequency equations have been derived in the form of a determinant involving Bessel functions. Dispersion equation in each case has been...

In previous and in work to be published, it has been shown that iron sulphide material, produced by sulphate-reducing bacteria (SRB), is an excellent adsorbent for a wide range of heavy metals. The material adsorbs between 100 and 400 mg g~1 and residual levels in solutions can be of the order of pg per litre. Further, strongly magnetic forms of this material can now be produced which can be e!...

Concurrent hyperthermia and radiation therapy in treatment of cancer show a strong evidence of a synergistic enhancement. We designed a new self-regulating Thermo-Brachytherapy seed, which serves as a source of both radiation and heat for concurrent administration of brachytherapy and hyperthermia. The Thermo-Brachytherapy seed has a core of ferromagnetic material which produces heat when subje...

   Magnetic nanoparticles are of great interest for researchers from a wide range of disciplines, including nano-magnetic fluids, nanocatalysis, biomedical applications, magnetic resonance imaging, and specifically environmental remediation. Nanomaterial like Iron Oxide (Fe3O4) is one of the most promising candidates to remove heavy metals and dyestuffs from the indust...
