We present a laboratory calibration setup for the individual multi-point calibration of oxygen sensors. It is based on the electrochemical generation of oxygen in an electrolytic carrier solution. Under thorough control of the conditions, i.e., temperature, carrier solution flow rate, and electrolytic current, the amount of oxygen is strictly given by Faradays laws and can be controlled to with...

Little is known about the ground-dwelling arthropod diversity in tropical montane cloud forests (TMCF). Due to unique habitat conditions in TMCFs with continuously wet substrates and a waterlogged forest floor along with the innate biases of the pitfall trap, Berlese funnel and Winkler extractor are certain to make it difficult to choose the most appropriate method to sample the ground-dwelling...

The Winkler extraction is one of the two fundamental sampling techniques of the standardized "Ants of the Leaf Litter" protocol, which aims to allow qualitative and quantitative comparisons of ant (Hymenoptera: Formicidae) assemblages. To achieve this objective, it is essential that the standard 48-hour extraction provides a reliable picture of the assemblages under study. Here, we tested to wh...

Over the last years, time-efficient approaches for the discovery of links between knowledge bases have been regarded as a key requirement towards implementing the idea of a Data Web. Thus, efficient and effective measures for comparing the labels of resources are central to facilitate the discovery of links between datasets on the Web of Data as well as their integration and fusion. We present ...

The paper studies the performance of Offshore Wind Turbines (OWTs) founded on Suction Bucket Jackets (SBJs) in clay under combined wind and seismic loading. A detailed 3D FE model soil–foundation–structure (SFS) system is developed used as a benchmark to assess efficiency an enhanced Winkler-based "Caisson-on-Winkler-Soil" (CWS) model, where soil replaced by nonlinear hysteretic elements. propo...
