Selection of R14-tyres using Analytic Hierarchical Process on the Basis of Uniformity and Strength
Abstract: Tyres play a commanding role in an automobile industry. Balancing and safety of the vehicle are the primary issues for automobile industry. These two parameters are highly dependent on the uniformity and strength of the tyres. There are various criteria that affect tyres uniformity and strength. Consequently, selection of tyres is a Multi-criteria Decision Making (MCDM) problem. In that respect are many methods available for selection of tyres; however, this …

Review on Increasing the Kappa Reduction in Oxygen Delignification Stage at Pulp Mills
Abstract: The use of oxygen delignification in bleached kraft pulp mills to reduce the lignin content of pulp prior to final bleaching is increasing worldwide. However, oxygen treatments are normally limited to less than 50% lignin removal to avoid excessive loss of pulp strength potential. More selective oxygen delignification processes are required which can extend lignin removal beyond 50% while maintaining final pulp quality. Work reported here has shown that pulp …
