BACKGROUND Recruitment rates in multi-centre randomised trials often fall below target recruitment rates, causing problems for study outcomes. The Studies Within A Trial (SWAT) Programme, established by the All-Ireland Hub for Trials Methodology Research in collaboration with the Medical Research Council Network of Hubs in the United Kingdom and others, is developing methods for evaluating aspe...

The Chinese species of the genus Ismarus Haliday, 1835, are revised for the first time. Three new species from the Oriental region of China and belonging to Ismarus halidayi-group are described and illustrated: Ismarus longussp. n., Ismarus nigritrochantersp. n. and Ismarus parvicellussp. n. Two species are newly reported for the Chinese fauna: Ismarus dorsiger (Haliday, 1831) and Ismarus halid...

The SWAT (Soil and Water Assessment Tool) model was used to estimate terrestrial sediment and nutrients loads to the Galveston and Matagorda bays from their contributing watersheds. In this report, the term "terrestrial loads" represents the sum of gauged loads from gauged subbasins and model-generated loads from ungauged subbasins. Because we did not have access to the point sources data, the ...

The accuracy of agricultural nonpoint source pollution models depends in part on how well model input parameters describe the relevant characteristics of the watershed. The spatial extent of input parameter aggregation has previously been shown to have a substantial impact on model output. This study investigates this problem using the Soil and Water Assessment Tool (SWAT), a distributed-parame...

Spatial accuracy of hydrologic modeling inputs influences the output from hydrologic models. A pertinent question is to know the optimal level of soil sampling or how many soil samples are needed for model input, in order to improve model predictions. In this study, measured soil properties were clustered into five different configurations as inputs to the Soil and Water Assessment Tool (SWAT) ...

In this study, we evaluate the performance of the SWAT-N model, a modified version of the widely used SWAT version, for discharge and nitrate predictions at the mesoscale Dill catchment (Germany) for a 5-year period. The underlying question is, whether the model efficiency is sufficient for scenario analysis of land-use changes on both water quantity and quality. The Shuffled Complex Evolution ...
