An (m, M) machine repair problem with spares and state dependent rates: A diffusion process approach
(1997)The diffusion approximation model for (m, M) general machine repair problems with spare part support has been developed. The inter-failure time and repair times are assumed to be generally identically and independently ... -
Macroaffinity ligand-facilitated three-phase partitioning for purification of glucoamylase and pullulanase using alginate
(2003)Starch-degrading enzymes glucoamylase (from Aspergillus niger), and pullulanase (from Bacillus acidopullulyticus) were purified using alginates (polysaccharides consisting of mannuronic acids and guluronic acids) by a ... -
Macromolecular investigations by laser light scattering
(1995)In a liquid suspension the small particles dance around randomly executing Brownian motion. When laser light is focussed onto such a solution, the total light scattered consists of a superposition of the light scattered ... -
Magnetic alginate microparticles for purification of α-amylases
(2003)Spherical magnetic alginate microparticles (25–60 μm in diameter) were prepared using the microemulsion system, with water-saturated 1-pentanol as the organic phase. The limited solubility of 1-pentanol in water enabled ... -
Magnetic properties of In3+ and Cr3+ substituted Mg–Mn ferrites
(2002)Two series of magnesium–manganese ferrites, viz., Mg0.9Mn0.1InxFe2−xO4 and Mg0.9Mn0.1CryFe2−yO4 have been prepared using conventional ceramic technique. Magnetic properties such as saturation magnetization (Ms), Curie ...
