Virtual City Experimentation: A Critical Role for Design Visioning

Here we introduce the idea of virtual city experimentation: a design approach to catalyse action in the context of rapidly emerging disruptive challenges to the fabric and life of cities. In the meaning we give to the term, the concept of virtual experimentation owes little to the contemporary association of ‘virtual’ with ‘digital’, or ‘on-line’. Independent of any technology used in the process,

Creation, Development and Impact of the General Principles of Community Law: Towards a jus commune europaeum?

The aim of this research is two-fold. First, the general principles of Community law are analyzed as "legitimacy principles", which permit the European Court of Justice to review the acts of the institutions and the Member States. Second, the basic assessment is to reckon the general principles of Community law as effective tools for the building of a jus commune europaeum when they "travel back"

Regulation of ornithine decarboxylase expression

It has become increasingly obvious during the last two decades that a multitude of cellular processes are highly dependent on adequate levels of polyamines (1–6). Too high concentrations of the polyamines are toxic to the cell and may induce cell death or apoptosis (7). On the other hand, too low concentrations may negatively affect anabolic events, such as the synthesis of DNA, RNA, and protein,

Co-Evolution of Technology, Markets and Institutions - the Case of Fuel Cells and Hydrogen Technology in Europe

The birth, growth and maturity of industries, sectors and technologies have spurred the curiosity of researchers as well as managers and policy makers for a long time. Intriguingly, the emergence of a new industry is a complex process including many different actors and with a high level of uncertainty related to technology, institutions and markets facing the actors involved. Empirically this b

Steam Pressure Control During Web Breaks in the Paper Machine

A new control strategy for steam pressure control inthe drying cylinders during web breaks is presented. The developmentis performed using a new physical model implemented inSimulink. The goal of the control strategy is that thecylinder temperatures are retained whenthe production is restarted after the web break.
