Hydroinformatics in multi-colours—part green: applications in aquatic ecosystem modelling
The present paper focuses on demonstrating the capabilities of modern hydroinformatics tools in the field of environmental systems by integrating biotic and abiotic process modelling. Abiotic processes like hydrodynamic flow and transport phenomena are often formulated based on physical principles like conservation of mass, momentum and energy. These processes are adequately represented ...

Cyst-Based Toxicity Tests. - I. A Promising New Tool for Rapid and Cost Effective Toxicity Screening of Chemicals and Effluents
Abstract : The determination of the toxicity of effluents and wastes at the aid of biological tests (bioassays) is hampered very seriously by the necessity of continuous culturing or maintenance of live stocks of test organisms in sufficient numbers and in a healthy state. Consequently such assays are (and can) only be performed in specialized laboratories and in limited number because of the ...
