Comparative study using spectroscopic and mineralogical fingerprinting for suspended sediment source apportionment in a river-reservoir system [PDF]

The need to control soil erosion has received increasing attention, but quantitative data on the sources of suspended sediment in many river–reservoir systems is still lacking.

Sensitivity of source apportionment predicted by a Bayesian tracer mixing model to the inclusion of a sediment connectivity index as an informative prior: Illustration using the Kharka catchment (Nepal)

, 2020
Long-chain saturated fatty acid (LCSFA) isotopic composition in tandem with Bayesian isotope mixing models (BIMM) can provide insight into land use-based sediment sources in catchment systems.

Uncovering renewable energy policy impact channels on land values, the local farm structure, and farmland heterogeneity

American Journal of Agricultural Economics, EarlyView.
Abstract Germany's Renewable Energy Sources Act (REA), enacted in 2000 and subsequently amended, subsidized national renewable energy production with fixed feed‐in tariffs for renewable energy sources (RE) from wind, solar, and biogas. Empirical studies suggest that the policy was creating windfall effects for landowners and attribute farmland use ...

Atmospheric polycyclic aromatic hydrocarbons in the urban environment: Occurrence, toxicity and source apportionment

, 2015
Polycyclic Aromatic Hydrocarbons (PAHs) represent a major class of toxic pollutants because of their carcinogenic and mutagenic characteristics. People living in urban areas are regularly exposed to PAHs because of abundance of their emission sources ...

Lost ground, lost value: Investigating the relationship between soil erosion and agricultural land value

American Journal of Agricultural Economics, EarlyView.
Abstract This study examines the impact of soil erosion on agricultural land values in the United States (US) Midwest. Based on a novel county‐level panel data set with information on soil erosion levels and agricultural land values covering five census years (1997, 2002, 2007, 2012, and 2017), we separately investigate the direct effect of two types ...

An explainable integrated optimization methodology for source apportionment of ambient particulate matter components

, 2022
Source apportionment of fine particulate matter (PM2.5) components is crucial for air pollution control. Prediction accuracies by the chemical transport model (CTM) significantly affect source apportionment results. Many efforts have been made to improve

The 9th International RASopathies Symposium

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The RASopathies are a group of congenital disorders with overlapping clinical manifestations that are caused by pathogenic germline or early somatic variants that result in the hyperactivation of the RAS/mitogen‐activated protein kinase (MAPK) signaling pathway.

Snow‐Induced Perturbations in Nitrous Acid (HONO) Levels: Insights Into Heterogeneous Reactions During Wintertime in Mid‐Latitude Regions

Geophysical Research Letters
Nitrous acid (HONO) governs wintertime hydroxyl radical (OH) production, critically linking radical cycling, tropospheric oxidative capacity, and air pollution. During a mid‐latitude snowfall event, rapid HONO enrichment was observed alongside concurrent

Sensitivity of fluvial sediment source apportionment to mixing model assumptions: A Bayesian model comparison

Water Resources Research, 2014
Mixing models have become increasingly common tools for apportioning fluvial sediment load to various sediment sources across catchments using a wide variety of Bayesian and frequentist modeling approaches.
