Bioprocess design problems are frequentlymultivariate and complex. However, they may be visualised by a graphical representation of the design constraints and correlations governing both the process and system under consideration, namely windows of operation. Windows of operation exist at all stages

Abstract
The operation of bioprocesses involves handling many variables with complex interactions. The visualisation of interactions is vital if suitable conclusions are to be drawn. This paper extends the previously developed ‘Windows of Operation’ to three dimensions, enabling the effects of three parameters to be visualised simultaneously. A tool with a graphical user interface has been developed to enable the generation of ‘3D‐Windows of Operation’ and the visualisation of the effects of the variation of any three control variables. Its use is illustrated with simulations of enzyme production. A number of control variables and the effects of the imposition of constraints on the range of possible operating values are investigated. Changes in the range possible are related to the variation in specific constraints or variables. Finally, it is illustrated how these diagrams and operation heuristics may be used to select suitable operating conditions for the bioprocess. Copyright © 2004 Society of Chemical Industry

This paper demonstrates a simple graphical approach for the design and analysis of a bioprocess flowsheet in which process interactions are significant. Results are presented showing how the feasible space for operation can be simulated and used both to address key design and operating decisions and
Thermotherapeutic tools are increasingly used for tissue ablation, although the intra-operative monitoring is not adequate for such procedures. This is a main challenge for more extensive use of any ablative technique. The present work focuses on treatment of hepatic tumours by cryo therapy. For any
## Abstract It is well known that the electrode structure of a PEMFC has a huge influence on the water management and thereby on the cell performance. In this work, two MEAs – one prepared by an airbrushing technique and the other by a novel fast spray coating technique (multilayered MEA) – were an
