Objective: Illicitly manufactured fentanyl has largely replaced heroin throughout the United States. Characteristics of fentanyl-specific withdrawal are not well understood compared to traditional opioid withdrawal. This study examines opioid withdrawal severity among 2 cohorts of study participants who underwent identical morphine stabilization procedures before and after fentanyl was introduced to the local drug market.

To ensure the future sustainability of arable land, it is essential to improve our understanding of the factors that influence soil erosion processes. This work aimed to evaluate patterns of soil erosion using the activity of plutonium isotopes (Pu) at sites with different land use and clearance scale in the Winam Gulf catchment of Lake Victoria in Kenya.

- - Land degradation from soil erosion is a significant global issue, especially in developing countries where resources are limited, and using fallout radionuclides (FRNs) can help assess soil erosion rates.
- - This research focused on using plutonium (Pu) as an effective soil erosion tracer in western Kenya, finding it superior to traditional isotopes like lead (Pb) and cesium (Cs) in accuracy and reliability.
- - The study revealed that Pu can effectively identify soil erosion patterns, with its maximum activity occurring between 3 and 12 cm depths, making it a valuable resource for developing strategies to address land degradation in the region.
