Prenatal Nitrate Intake from Drinking Water and Selected Birth Defects in Offspring of Participants in the National Birth Defects Prevention Study
Jean D. Brender,Peter J. Weyer,Paul A. Romitti,Binayak P. Mohanty,Mayura Shinde,Ann M. Vuong,Joseph R. Sharkey,Dipankar Dwivedi,Scott Horel,Jiji Kantamneni,John C. Huber,Qi Zheng,Martha M. Werler,Katherine E. Kelley,John S. Griesenbeck,F. Benjamin Zhan,Peter H. Langlois,Lucina Suarez,Mark A. Canfield +18 more
TL;DR: Higher water nitrate intake was associated with several birth defects in offspring, but did not strengthen associations between nitrosatable drugs and birth defects.
Journal ArticleDOI
The East River, Colorado, watershed: A mountainous community testbed for improving predictive understanding of multiscale hydrological–biogeochemical dynamics
Susan S. Hubbard,Kenneth H. Williams,Deb Agarwal,Jillian F. Banfield,Harry R. Beller,Nicholas J. Bouskill,Eoin L. Brodie,Rosemary W.H. Carroll,Baptiste Dafflon,Dipankar Dwivedi,Nicola Falco,Boris Faybishenko,Reed M. Maxwell,Peter S. Nico,Carl I. Steefel,Heidi Steltzer,Tetsu K. Tokunaga,Phuong A. Tran,Haruko Wainwright,Charuleka Varadharajan +19 more
TL;DR: In this paper, an approximately 300-km2 mountainous headwater observatory has been developed at the East River, CO, watershed of the Upper Colorado River Basin, which is used as a testbed for the Department of Energy supported Watershed Function Project and collaborative efforts.
Journal ArticleDOI
Long residence times of rapidly decomposable soil organic matter: application of a multi-phase, multi-component, and vertically resolved model (BAMS1) to soil carbon dynamics
William J. Riley,Federico Maggi,Markus Kleber,Margaret S. Torn,Jinyun Tang,Dipankar Dwivedi,N. Guerry +6 more
TL;DR: In this paper, the authors developed an organic matter reaction network integrated in a one-dimensional, multi-phase, and multi-component reactive transport solver to investigate how various mechanisms interact to influence organic matter storage and dynamics.
Journal ArticleDOI
Particulate emission characterization of a biodiesel vs diesel-fuelled compression ignition transport engine: A comparative study
TL;DR: In this paper, a medium duty, transport diesel engine (Mahindra MDI 3000) was operated at idling, 25, 50, 75% and rated load at maximum torque speed (1800 rpm) and samples of particulate were collected using a partial flow dilution tunnel for both fuels.
Journal ArticleDOI
Hot Spots and Hot Moments of Nitrogen in a Riparian Corridor
TL;DR: Dwivedi et al. as discussed by the authors used 3D high-resolution reactive transport modeling to investigate whether the spatial distribution of organic carbon-rich and chemically reduced sediments located in the riparian zone and temporal variability in groundwater flow direction impact the formation and distribution of nitrogen hot spots (regions that exhibit higher reaction rates when compared to other locations nearby) and hot moments (times that exhibit high reaction rates as compared to longer intervening time periods) within the Rifle floodplain in Colorado.
