RECYCLING PRACTICES OF SPENT MgO-C REFRACTORIES
The recycling options of spent MgO-C refractories from an electrical arc furnace (EAF) have been evaluated. The economic, quality of spent refractories and products made from it, the ease of implementation of a recycling practice and the interest of steel melt shops were considered. It was decided that the best option of most EAF shops would be to recycle spent MgO-C refractory as a foaming sla...
متن کاملKinetics and Mechanism of Mitomycin C Bioactivation by Xanthine Dehydrogenase under Aerobic and Hypoxie Conditions1
These studies examined the kinetic and mechanistic parameters of mi tomycin C (MMC) bioreduction by xanthine dehydrogenase (XDH), an enzyme recently shown to be capable of MMC activation. The bioreduc tion of MMC by XDH leads to the formation of 2,7-diaminomitosene (2,7-DM) under both aerobic and hypoxic conditions, with greater 2,7-DM formation observed under hypoxic conditions. The XDH-induce...
متن کاملQuality of Life: the Differential Conditions1
57 INTRODUCTION A considerable number of works have, in recent years, attempted to define or study the concept of quality of life (QoL) (for a review, see Fernndez-Ballesteros 1993, 1998). It can indeed be said that the progress of research on this construct, which can be found in a variety of different bibliographical databases Ðecological (ÒUrbanÓ), biological (ÒBiosisÓ), medical (ÒMedlineÓ)...
متن کاملCharacterization of lipoproteins produced by the human liver cell line, Hep G2, under defined conditions1
Confluent monolayers of the human hepatoblastoma-derived cell line, Hep G2, were incubated in serum-free medium. Conditioned medium was ultracentrifugally separated into d < 1.063 g/ml and d 1.063-1.20 g/ml fractions since very little VLDL was observed. The d < 1.063 g/ml fraction was examined by electron microscopy; it contained particles of 24.5 * 2.3 nm diameter, similar in size to plasma LD...
متن کاملPolymer Brushes under High Load
Polymer coatings are frequently used to provide repulsive forces between surfaces in solution. After 25 years of design and study, a quantitative model to explain and predict repulsion under strong compression is still lacking. Here, we combine experiments, simulations, and theory to study polymer coatings under high loads and demonstrate a validated model for the repulsive forces, proposing th...
