new drug delivery system uses magnetism. researchers in boston introduce a tiny implantable device whose membrane releases drugs with extreme precision, on demand, when triggered by a magnetic field.
during world war ii, steve rogers volunteered to receive the experimental super-soldier serum. enhanced to the pinnacle of human physical potential and armed with an unbreakable shield, he became
senses: the lone wanderer's senses are all far in excess of human capacity, he can see in all parts of the spectrum and can magnify his vision to the very limits that their wavelengths will allow
they are mainly used to separate ferromagnetic materials such as magnetite artificial magnetite, titaniferous magnetite, or grinding iron. they are widely used and established in the iron ore industry and the separating characteristics are simple applications of the principles discussed. high intensity wet magnetic separators.
the simplest form of magnetic separation is by hand magnet, a procedure which works for only one common mineral - magnetite. other minerals having magnetic susceptibility are separated by using an apparatus that can generate strong electromagnetic fields. the frantz separator (fig. 1) incorporates an electromagnet with
breath of life from mars? say that a crystallized magnetic mineral, called magnetite, found in a martian meteorite is similar to crystals formed on earth by bacteria. of lakes produce
magnetic separators can be found in most mineral processing operations, especially those processing non-metallic minerals and magnetic ores. this article investigates the use of high intensity magnetic separators and magnetic separation equipment in the minerals sector with a focus on processing dry materials (in the -15mm, 45 micron size range).
