  • A resistance of magnesium alloys to surface degradation is paramount for their applications in automotive, aerospace, consumer electronics and general-purpose markets. An emphasis of this book is on oxidation, corrosion and surface modifications, designed to enhance the alloy surface stability. It covers a nature of oxides grown at elevated temperatures and oxidation characteristics of selected alloys along with elements of general and electrochemical corrosion.

  • Of late, the coastal ecosystems are highly degraded due to high population and industrial growth (Glasby & Roonwal, 1995; UNEP, 1997). Due to various pollutions including pesticide poisoning (Sen Gupta et al., 1990), over exploitation of water resources by power plant industries and the municipal uses and encroachment for urban developments force the fishing community to the brink of disappearance. When those natural resources are imperilled, so too are the livelihoods of the many people who live and work there.

  • a-enolase (ENOA) is a metabolic enzyme involved in the synthesis of pyru-vate. It also acts as a plasminogen receptor and thus mediates activation of plasmin and extracellular matrix degradation. In tumor cells, EMOAis upregulated and supports anaerobic proliferation (Warburg effect), it is expressed at the cell surface, where it promotes cancer invasion

  • Methioninec-lyase (MGL) (EC 4.4.1.11), which is present in certain lin-eages of bacteria, plants, and protozoa but missing in mammals, catalyzes the single-step degradation of sulfur-containing amino acids (SAAs) to a-keto acids, ammonia, and thiol compounds.
