this paper provides an overview of how the surface properties of ferromagnetic nanoparticles dispersed in fluids is modified by natural and biocompatible polymers. among common magnetic nanoparticles, magnetite (fe3o4) and maghemite (g-fe203) are popular candidates because of their biocompatibility. natural polymeric coating materials are the most commonly used biocompatible magnetic nanopartic...

quarter was regulated between 18? and 25•Ž. Incidence of lung tumor among thus treated mice was very high at the age of 3 months exceeding 75%. Whereas, among the untreated controls and mice administered the identical agent or subcutaneous injection of methylcholanthrene-rosin pellet2) 30 days after birth the incidence was very low and retarded, not exceeding 1 % and being detected after 8 mont...

Rosin, P.L., A note on the least squares fitting of ellipses, Pattern Recognition Letters 14 (1993) 799-808. The characteristics of two normalisations for the general conic equation are investigated for use in least squares fitting: either setting F = 1 or A + C= 1. The normalisations vary in three main areas: curvature bias, singularities, transformational invariance. It is shown that setting ...
