Pesticide trapping efficiency of vegetated filter strips (VFS) is commonly predicted with low success using empirical equations based solely on physical characteristics such as width and slope. The objective of this research was to develop and evaluate an empirical model with a foundation of VFS hydrological, sedimentological, and chemical specific(More)
The GIS based decision support system DRIPS--Drainage Spraydrift and Runoff Input of Pesticides in Surface Waters--has been developed to estimate the predicted environmental concentration (PECsw) of pesticides in surface waters resulting from diffuse sources. PECsw can be calculated on a catchment scale by quantifying the expected mean daily inputs of(More)
The development of the GIS Decision Support System (DSS) – Drainage Runoff Input of Pesticides in Surface Water based on model algorithms describing the major pathways of pesticide entry into surface waters has been initiated by the German Federal Environmental Agency (Umweltbundesamt, UBA) in 2000. The tool estimates the quantity of pesticide input from(More)
1.Research Description: In my PhD thesis at the Ruhr University Bochum I focused on functional genomic and proteomic approaches to unveil the potential role and function of gap junctional communication in differentiation and development. Gap junctions are specialized channels formed by members of the Connexin (Cx) gene family, that mediate cell-to-cell(More)
