One mechanism of silver resistance in microorganisms is accumulation of the metal ions in the cell. Here, we report on the phenomenon of biosynthesis of silver-based single crystals with well-defined compositions and shapes, such as equilateral triangles and hexagons, in Pseudomonas stutzeri AG259. The crystals were up to 200 nm in size and were often(More)
The oxidizing activity of CYP109B1 from Bacillus subtilis was reconstituted in vitro with various artificial redox proteins including putidaredoxin reductase and putidaredoxin from Pseudomonas putida, truncated bovine adrenodoxin reductase and adrenodoxin, flavodoxin reductase and flavodoxin from Escherichia coli, and two flavodoxins from B. subtilis (YkuN(More)
Nitrated polycyclic aromatic hydrocarbons (NPAHs) and N-heterocyclic aromatic hydrocarbons (azaarenes) are as ubiquitous in the environment as their parent PAH compounds, although occurring at lower concentrations. The toxicological importance of NPAHs and azaarenes is based on their mutagenic and carcinogenic potential. Azaarenes possess a higher(More)
Robotics systems usually comprise sophisticated sensor and actuator systems with no less complex control applications. These systems are subject to frequent modifications and extensions and have to adapt to their environment. While automation systems are tailored to particular production processes, autonomous vehicles must adaptively switch their sensors(More)
Although the manual creation of time-triggered schedules for multi-core real-time systems can be a daunting task, state-of-the-art scheduling algorithms are far from being widely used. This suggests that the availability of sound algorithms is only one side of the story: real-time systems have to be groomed substantially before they can serve as input to(More)
Current trends, such as mixed-criticality real-time systems, boost performance by leveraging system dynamics and adaptivity, but also amplify challenges for control engineering and real-time-system design. Applications behave more adaptively and more applications will be consolidated on the same realtime system competing for the same resources, turning(More)
We believe that the Application Programming Interfaces (APIs) is a commonly ignored but very important property of a real-time operating system (RTOS). It should not only be complete i. e., offer all mechanisms needed to implement common real-time systems, but also be easy to use in order to prevent programming errors and make real-time systems more(More)
Current trends, such as mixed-criticality real-time systems, boost performance by leveraging system dynamics and adaptivity. This, however, also amplifies challenges for control engineering and real-time-system design. Experiments with control applications indicate problems with traditional assumptions such as ‘better response times will not decrease the(More)
In neoclassical economic theory, rational actors are very simple entities: they know everything, they value more better than less, and given a decision situation with certain physical constraints they are able to calculate the optimal outcome and to behave accordingly (cf. Kiser/Ostrom). Any form of social interaction enters the decision situation as an(More)
