A fedbatch process shows exponential growth under ideal conditions. To obtain good substrate concentration control it is necessary that the regulator can track an exponentially growing feed demand, and standard PI-control has to be supplemented with an estimated basic dosage to get reasonable control. However, an exponentially growing concentration error is impossible to avoid. An I-term could be
This is a study of farm dynamics in eight African countries, drawing on a sample of more than 3000 farm households. It deals mainly with food crops and in detail with maize and makes a longitudinal analysis by systematically comparing current conditions with those obtaining when the farm was set up under its present management.

The stakeholders struggle in a lower violence capacity but broad range of conflicting issues. Thus, some parties may use cooperative or/and competitive conflict management approaches to achieve their goals. This thesis argues that different political st
Sustainable development rests on, among other things, the ability of policy to stimulate corporate actors to improve their environmental performance. Yet policy design and implementation is a challenging task in this area. This paper investigates this issue by examining the ability of the UK Emissions Trading Scheme to foster corporate sustainability from two perspectives: (a) its institutional fr
