Nitrogen and Phosphorus in Large Rivers
Nitrogen is a critical nutrient for plants and animals, and terrestrial ecosystems and headwater streams have a considerable ability to capture nitrogen or to reduce it to N2 gas though the process of denitrification. Nitrogen cycling and retention is thus one of the most important functions of ecosystems (Vitousek et al., 2002). When loads of nitrogen from fertilizer, septic tanks, and atmosph...
متن کاملTrends in concentrations and use of agricultural herbicides for Corn Belt rivers, 1996-2006.
Trends in the concentrations and agricultural use of four herbicides (atrazine, acetochlor, metolachlor, and alachlor) were evaluated for major rivers of the Corn Belt for two partially overlapping time periods: 1996-2002 and 2000-2006. Trends were analyzed for 11 sites on the mainstems and selected tributaries in the Ohio, Upper Mississippi, and Missouri River Basins. Concentration trends were...

The aim of this study was to give an overview of smoking behaviour among Estonian physicians from 1982 to 2014. METHODS Three cross-sectional postal surveys using a self-administered questionnaire ...
متن کاملPrediction of pesticide concentrations found in rivers in the UK.
SWATCATCH is a distributed model combined with databases within a GIS as the POPPIE system to predict pesticide concentrations in rivers at the catchment outlet. The model was evaluated against a dataset of pesticide concentrations in rivers of England and Wales. More than 2000 individual analyses in each of the years 1995 and 1997 covered approximately 150 catchment-pesticide combinations draw...
متن کاملTowards an Integration of Syntactic and Temporal Annotations in Estonian
We investigate the question how manually created syntactic annotations can be used to analyse and improve consistency in manually created temporal annotations. Our work introduces an annotation project for Estonian, where temporal annotations in TimeML framework were manually added to a corpus containing gold standard morphological and dependency syntactic annotations. In the first part of our ...
