Combined impact of land cover, precipitation, and catchment area on discharge and phosphorus in the Mississippi basin's subcatchments.

Phosphorus (P) supplies (concentrations and fluxes) are essential drivers for biological activities in rivers and should be controlled to prevent eutrophication that usually results from urbanization and agricultural expansion. In this study, data from 26 subcatchments in the Mississippi basin were compiled from 2013 to 2017 to identify how catchment area, precipitation, and land cover affect discharge and total P (TP) and how TP yield diverges from a generalized local response mode. Results revealed that area-weighted discharge (Q ) is controlled by precipitation and land cover (i.

Evaluation of general practitioners' training: how to manage patients with unexplained physical symptoms.

Patients with unexplained physical symptoms ("somatoform disorders") tend to overuse the healthcare system. Therefore, the authors aimed to assess whether a training session for general practitioners (GPs) on managing patients with unexplained physical symptoms would be acceptable to GPs and lead to improvements in patient care. In a randomized clinical trial (GPs randomized), GPs got a 1-day training session and additional materials.
