We present a disposable microarray hybridization chamber with an integrated micropump to speed up diffusion based reaction kinetics by generating convective flow. The time-to-result for the hybridization reaction was reduced from 60 min (standard protocol) down to 15 min for a commercially available microarray. The integrated displacement micropump is pneumatically actuated. It includes two active microvalves and is designed for low-cost, high volume manufacturing. The setup is made out of two microstructured polymer parts realized in polycarbonate (PC) separated by a 25 μm thermoplastic elastomer (TPE) membrane. Pump rate can be controlled between 0.3 μl s(-1) and 5.7 μl s(-1) at actuation frequencies between 0.2 Hz and 8.0 Hz, respectively.

Abstract. In the past, attempts were made to make law and justice more accessible to general audience and to legal practitioners using models of legal texts. We present a new approach to make the judicial workflows easier to understand. By using process modelling methods, the developed representation emphasises on improving transparency, on promoting mutual trust and on formalising models for verification. To design semi-formal models interviews are used as well as legal texts are consulted. These models are formalised in a second step. The models are enhanced with hierarchies, modules and the generation of different views. Language problems are also treated. The subsequent formalised models are used to verify trigger events and timing of judicial workflows, which have very specific requirements in terms of periods of time and fixed dates. A new tool, Lexecute, is presented which gives new perspectives into justice and reveal new potentials for modelling methods in the field of justice.The results presented in this paper have been achieved in the context of eJustice, an EU-project within the 6th framework programme (see www.ejustice.eu.com). eJustice is bringing together experts from the field of informatics and law, developing solutions to enable the European justice for a closer collaboration. One major part of eJustice, that will be presented here, is the development of a proper representation for judicial workflows.We present the new tool Lexecute that combines a graphical representation of legal processes with a detailed description of all steps of these processes. Lexecute supports the work of judicial practioners for several reasons: -A workflow model helps to visualise the process described. One can get a quick overview over the procedure without having to concern huge texts. A visualisation can be realised in such a self-descriptive way that it is understandable even by amateurs and not only by legal experts.
