Artificial Neural Networks for Defining the Operational Parameters of Sand Filters for Irrigation
Irrigation and Drainage, EarlyView.ABSTRACT The difficulty in defining the working configuration during the operation of sand filters arises from the complexity of the relationships among the variables in the filtration and backwashing processes. The objective was to use artificial neural networks to model the pressure loss and removal efficiency of filtration in a commercial sand ...

Journal of Applied Toxicology, EarlyView.ABSTRACT Acephate is an organophosphate insecticide widely used. This pesticide can be metabolized into methamidophos, a molecule highly toxic. Both have demonstrated the ability to promote serious toxic effects on nontarget organisms and have been identified in surface waters around the world. Therefore, it is important to understand their behavior in

Journal of Applied Toxicology, EarlyView.ABSTRACT Environmental exposure to heavy metals poses a threat to human health. Several studies documented harmful effects on the liver after arsenic and nickel exposure at concentrations beyond permissible limits. Nevertheless, the impact of a simultaneous exposure to both elements on hepatic biochemistry and histology remains unelucidated. Therefore,

Journal of Chemical Technology &Biotechnology, EarlyView.Abstract Background Efficient dewatering is a critical step in cassava starch production because the moisture content of the concentrated slurry directly affects downstream drying costs and overall process efficiency. Conventional concentration routes, including sedimentation and centrifugation, often provide limited cake dryness and can increase ...
