Knovel Corporation, a Web-based reference service that provides interactivity to scientific and technical information for engineers, scientists, and students online, has released thirty-five new references now available online. Knovel's content, all full-text, is enhanced with productivity tools like interactive tables, graphing applets, and calculation packages merged into an interface. These features, combined with search capabilities, are designed to help users find answers to their science and engineering questions. By the end of 2003 Knovel expects to have nearly 20 million data records from over 600 sources. New subjects and titles include: Ceramics & Ceramic Engineering (Crystal Growth Technology); Chemistry & Chemical Engineering (Deflagration and Detonation Arresters; Estimating the Flammable Mass of a Vapor Cloud; Evaluating Process Safety in the Chemical Industry - A User's Guide to Quantitative Risk Analysis; Guidelines for Process Safety in Batch Reaction Systems; Guidelines for Process Safety in Outsourced Manufacturing Operations; Layer of Protection Analysis - Simplified Process Risk Assessment; Making EHS an Integral Part of Process Design; and Revalidating Process Hazard Analyses); Electrical & Power Engineering (Handbook of Electric Power Calculations (3rd Edition)); Environment & Environmental Engineering (Environmental and Health Impact of Solid Waste Management Activities); Food Science (Meat Processing - Improving Quality); General Engineering References (Handbook of Material Weathering (3rd Edition); Handbook of Materials for Product Design); Mechanics & Mechanical Engineering (ASME Boiler and Pressure Vessel Code, Section II - Materials; Buried Pipe Design (2nd Edition); Mechanical Engineers' Handbook (2nd Edition); Peterson's Stress Concentration Factors (2nd Edition); Pumping Station Design (2nd Edition); Tribology in Machine Design); Pharmaceuticals, Cosmetics & Toiletries (Cosmetic and Toiletry Formulations, Volume 1-9 (2nd Edition); Pharmaceutical Manufacturing Encyclopedia, Volumes 1-2 (2nd Edition)); Plastics & Rubbers (ANTEC 1997 Plastics: Plastics Saving Planet Earth, Volumes 1-3; Permeability Properties of Plastics and Elastomers - A Guide to Packaging and Barrier Materials (2nd Edition); Technology of Plasticizers); Safety, Health & Hygiene (2000 Emergency Response Guidebook; Electrical Installations in Hazardous Areas; McGraw-Hill's National Electrical Safety Code (NESC®) Handbook).
