In six chapters this book introduces a micro-economic model where trade takes place through a stable structure of bilateral exchange institutions.The main problem in such models is that, for well-known equilibrium concepts, equilibrium may fail to exist in the corresponding game. In this work an adaptation of such models - hierarchically structured economies - is introduced. The possibilities and limitations of the use of the concept of subgame perfect equilibrium within the context of this kind of models is discussed. Furthermore, it is shown that some well-known market forms, viz. Walrasian...

The respiration rate of activated sludge has generated much interest, because it is an essential variable in the activated sludge process and provides information on biomass activity and concentration of waste components. Recognising the need for an extensive evaluation of respirometry in control of the activated sludge process, IWA published Scientific and Technical Report (STR7): Respirometry in Control of the Activated Sludge Process: Principles, which included the biological background, measuring principles, measured and deduced variables, an introduction to control system principles and...

In the modern energy-demanding lifestyle there is an overwhelming need for exploring sources of energy which are renewable and eco-friendly. Bioconversion of biowaste streams for energy production is an increasingly promising option. Through the biogas value chain, bioconversion presents a very attractive route to valorise various biowaste and enables communities to meet their energy needs, conserve resources and protect the environment. However there are challenges in sustainable implementation of biogas technology. The book has therefore reviewed the biogas value chain from a critical...
