Summary: This study evaluates the performance of response surface methodology as a machine learning technique for the gasification process of polyethylene waste. Different models are developed using response surface methodology to predict gas yield, cold gas efficiency, carbon dioxide emission, and lower heating value of syngas in polyethylene waste gasification. The accuracy and validity of these models are compared with results obtained from a validated model. The findings show that the models developed by response surface methodology have high validity, with root mean square errors below 5%.

Summary: The giant river prawn is a major focus of aquaculture in tropical and sub-tropical regions. As the demand for it has increased, its culture has also grown exponentially, but this has brought along the emergence of diseases that affect its yield, profit, and trading potential. This review examines the pathogens associated with the culture of the giant river prawn, with a focus on those initially identified in other aquaculture host species.
