Per- and polyfluoroalkyl substances (PFAS) increasingly appear in organic recycling streams, yet their behaviour during full-scale windrow composting remains unclear. Thirty-three PFAS analytes were tracked through commercial composting of food organics and garden organics (FOGO) at 14, 30, and 45 days, and in finished compost. Total concentration analysis, leachability testing (ASLP), exploratory leachate assessment, total ox...

Genetic and other predisposing factors can influence the progression from initiation of drug intake to compulsive substance use through distinct biobehavioral processes. Operant cocaine self-administration studies in laboratory mice offer a powerful method to dissect the biology of this progression from initiation, dose-response, extinction, and cued reinstatement in a controlled, tractable system. However, many such studies e...

The San Joaquin Valley is one of the most intensive oil and gas and agricultural production regions of the United States, yet the regional groundwater salinity distribution is not well defined, particularly near the western margin of the valley where salinity is highly variable. Airborne electromagnetic (AEM) surveys were conducted to improve the understanding of the three-dimensional variations in groundwater salinity in the...
