Rotation is a fundamental mechanical motion and is crucial for biological and artificial systems at the micro-/nanoscale. In nature, biomolecular rotary motors drive bacterial flagella and ATP synthase.[1–3] Inspired by such rotary motors, various micro-/nanorotors have been developed,[4] including chemicaland light-driven artificial molecular rotors,[2,5](More)
Colorado potato beetle (CPB, Leptinotarsa decemlineata Say) (Coleoptera: Chrysomelidae) is one of the most serious insect pest feeding on wild and cultivated Solanaceae plants. This pest poses a significant threat to potato crops. CPB originated from North America but has become widespread and has adapted in new localizations. Currently, it is reported in(More)
Public organisations often face knowledge management problems caused by organisational mobility, the continual and pervasive movement of staff between units and departments. This can be a strength, but also introduces problems of loss of experience and reduced efficiency and effectiveness in working. The Pellucid project is developing a knowledge management(More)
Public organisations with a high rate of staff rotation lose their valuable asset – experience of employees. Mobile employees, who have to face duties at new positions, would find computer assistance helpful in efficient inception. The idea to support current work of employees on the basis of gathered experience in past activities is driving the Pellucid(More)
In this paper we present the use of ontology for knowledge representation and handling in Software Agent Systems. Motivation has come from Pellucid IST project where we need to capture and capitalize employee’s knowledge in organization. This knowledge is then presented to other employees as they work on particular tasks. The Protg ontology editor and JADE(More)
In this paper we present the use of ontology for knowledge representation and handling for Administration Processes. Motivation has come from Pellucid (Platform for Organizationally Mobile Public Employees) is European Project IST-2001-34519, where we need to capture and capitalize employee’s knowledge in an organization. This knowledge is then presented to(More)
The objective of this study was to characterize the effects of silver nanoparticles on Pseudomonas aeruginosa. Their interactions with several conventional antibiotics and ability to induce a stress response were examined. Interactions between silver nanoparticles (AgNPs) and antibiotics against free-living cells and biofilm of P. aeruginosa were studied(More)
In this paper we introduce an advanced experience management and recommendation framework. The framework exploits software agent technology to ensure distributed and robust functioning. In design and implementation we use state of the art methodologies, technologies and tools. Ontology is used for modeling and describing knowledge. The infrastructure is(More)
