The Second International Conference on Environmental Management (ICEM2) focuses on the engineering management of the water and geo environments and aims to bring together scientists, engineers and other professionals to review as well as to report on the latest developments in the field.

This book contains 160 peer reviewed papers covering the following interdisciplinary themes: Sustainable development/environmental management. Water, wastewater and stormwater management. Water quality/sediment transport. Total catchment management. Waste management and industrial waste products. Geotechnology and the environment. Slope stability and landslide management. Natural hazards and management. Mine environmental engineering.

Welding the Inconel 718 Superalloy: Reduction of Micro-segregation and Laves Phases explores the day-to-day welding business in Alloy 718 and presents solutions to avoid or minimize micro-segregation. It considers the limitations of changing from lab scale models to actual production models and presents new technologies with proven experimental background. Various case studies are presented within the text, as well as proposed solutions backed by experimental evidence. Items previewed in this edition include enhanced cooling rates in the GTA welding process with cryogenic cooling and enhanced dendrite refinement using modified pulse waveform.

This work will be useful to researchers from the aerospace, space, power generation, nuclear, and chemical industries, as well as students interested in superalloys and welding.

Resolves the industrial limitations in reducing the formation of laves phases in the welding of alloy 718 Presents case studies in industrial applications Discusses new technologies with proven experimental background Includes a comparison of laves size and distribution between GTAW, EBW, LBW and FW

This book constitutes the refereed proceedings of the 7th International Workshop on Algorithms and Models for the Web-Graph, WAW 2010, held in Stanford, CA, USA, in December 2010, which was co-located with the 6th International Workshop on Internet and Network Economics (WINE 2010).The 13 revised full papers and the invited paper presented were carefully reviewed and selected from 19 submissions.
