Pseudomonas aeruginosa navigates using two distinct forms of motility, swimming and twitching. A polar flagellum and Type 4 pili power these movements, respectively, allowing P. aeruginosa to attach to and colonize surfaces. Single cell imaging and particle tracking algorithms have revealed a wide range of bacterial surface behaviors which are regulated by second messengers cyclic-di-GMP and cA...

National security depends on soft power, the ability of a country to generate and use its economic power and to project its national values. It also depends on long-term factors that contribute to economic growth and increase the total resources base available not only for defense but to provide economic security in the form of income and business opportunities for individuals. The economic iss...

This report intends to give an overview over various aspects of distributed generation. Distributed Generation was favoured in the last few years due to the liberalisation process of the electricity infrastructure as well as to the impulse to produce electricity independent of fossil fuels. The number of small decentral installations of e.g. wind turbines, photovoltaic systems or combined-heat-...

As the conception of and debates on regional powers have been led by political science, this paper aims to contribute to the discussion from an economics perspective. Based on the discussion of different concepts of economic power—such as those of Schumpeter, Perroux, Predöhl, or Kindleberger—concepts of technological leadership, and the global value chain approaches, the paper develops a resea...

This research explores the idea that weather conditions and driverand vehiclepopulation characteristics affect a homogenous roadway segment’s flow-versus-density relationship. Third-order-polynomial regressions of flow on powers of density interacted with a variety of explanatory variables suggest that driver, vehicle, and environmental attributes significantly influence the flow-density relati...
