A comprehensive and up-to-date account of filtration in solid-liquid separation processes, with a sharp focus on the influence of pro-cess variables on performance and specific applications is pre-sented in this volume. With contribu-tions from researchers with significant industrial experi-ence, as well as by senior academics, this publication fea-tures a deep bed filtration overview with informa-tion on mathematical modeling and application in wastewater treat-ment. Pre-treatment filtration techniques such as cartridge filters, pre-coat filters and micro screening are included. Membrane filtration processes to remove dis-solved and suspended solids for the recovery of valuable ma-terials and the provision of high quality water are covered. Sludge de-watering methods such as centrifuga-tion, and vacuum and pressure filtration are described. Application status data, tables, figures and diagrams are also included. This volume is of special interest to practicing engineers and technolo-gists dealing with treatment problems requiring filtration solu-tions and to graduate students in environmental engineering.
The occurrence of strikes and lock-outs is an important feature of labour relations in industrialized market economies. These two types of concerted activity by industrial workers and civil servants are the direct result of the conflict of interest and ideology that is inherent in industrial relations. This conflict evolves around the questions of power distribution and group autonomy vis--vis the capital owners and the State. While the phenomenon of strikes and lock-outs has existed ever since the beginnings of industrial society, there have been some significant changes in the nature and occurrence of strikes and lock-outs in the past few decades. These changes and new trends that may be detected in today's forms of industrial action is one of the themes discussed in this volume of the Bulletin. To name two: An increased heterogeneity and specialisation within the labour force. The direction of industrial action against the general public, the consumers, rather than against the capital owners and the growing importance of the service sector employees within the working population. Developments such as these have an impact on labour relations and the accompanying conflicts such as strikes and lock-outs, as you will discover reading this new Bulletin.
Expert bowhunter Roger Maynard gives an in-depth look at what it takes to be successful in the hunt for game. Maynard explains it all based on his vast experience and from the advice of bowhunters and bow makers he has met over his 30-plus years of hunting.
Sellers has long been acknowledged as one of the screen's greatest comic actors. In this biography, Roger Lewis draws on over 300 interviews with Sellers's family, wives, mistresses, enemies and co-stars to show how he succeeded, and why it was at such a cost to himself and to those who he professed to love.
