Tannery wastewater is characterized by high organic loads, low biodegradability, and the presence of recalcitrant compounds, which hinder the efficiency of conventional treatment. In this study, ozonation was evaluated as a pretreatment step to enhance coagulation-flocculation performance for real tannery wastewater collected in southern Brazil. Coagulation-flocculation experiments were carried out using aluminum sulfate at di...

Population-based preventive trials are rare in psychiatry, especially in an aging population, and the effects of potentially modifiable lifestyle risk factors such as diet on mental health outcomes are largely unexplored. This study aimed to estimate the effects of an anti-inflammatory diet on mental health outcomes in older adults and the potential effect of lifestyle modification. A preventive population-based target trial w...

Herbivores select host plants depending on plant quality and the presence of predators and competitors. Competing herbivores change host plant quantity through consumption, but they can also change plant quality through induction of plant defences, and this affects the performance of herbivores that arrive later on the plant. Some herbivores, such as the spider mite Tetranychus evansi , do not induce, but suppress plant defenc...
