Anaerobic ammonium oxidation coupled with Fe(III) reduction (Feammox) is an essential process in the geochemical iron and nitrogen cycling. This study explores Feammox-based nitrogen removal in a continuous laboratory up-flow bioreactor stimulated by intermittently adding 5 mM Fe(OH) at intervals of approximately two months. The feed was synthetic wastewater with a relatively low ammonium concentration (∼100 mg N/L), yet without organic carbon in order to test its autotrophic nitrogen removal performance.

Objective: To evaluate the impact of tort reform laws passed in 2011 capping noneconomic damages in North Carolina and Tennessee on rates and adjusted per user costs of tests, imaging, and procedures in the Medicare fee-for-service population.
Study Setting And Design: State-level synthetic difference-in-differences, adjusting for the percent of FFS Medicare beneficiaries in the state who were female, had ever been on Medicare Advantage, were eligible for Medicaid for at least 1 month of the year, and total state risk-adjusted, standardized per-capita costs. Analyses of North Carolina and Tennessee were performed separately.

In this study, five strains previously isolated from black liquor (BL) and vinasse (V) were tested to assess the most promising regarding its capacity of biosurfactant production. For that, four factorial designs of two factors at two levels (2) were run for each strain. Selected factors were the production time and the composition media, while the surface tension reduction and optical density were the responses variables.

Background: The development of Artificial Intelligence in the healthcare sector is generating a great impact. However, one of the primary challenges for the implementation of this technology is the access to high-quality data due to issues in data collection and regulatory constraints, for which synthetic data is an emerging alternative. While previous research has reviewed synthetic data generation techniques, there is limited focus on their applications and the motivations driving their synthesis.
