Aims:The aim of this study was to investigate the effectiveness of freshwater green microalgae in remediating swine manure wastewater. Two different species of freshwater green microalgae (Scenedesmus quadricaudaand Stigeocloniumsp.) were used in this study.Methodology and results:Laboratory experiments were performed to compare the growth rate and nutrients (total phosphorus, ammonia nitrogen, nitrate nitrogen and nitrite nitrogen) uptake by these two species of microalgae in swine manure wastewater. Experimental work was carried out for 14 days at room temperature of 30±1 °C with about 1520 Lux of light intensity. The results showed that both microalgae grew well in swine manure wastewater. S.quadricaudaperformed better in remediating swine manure wastewater, by reducing 83.99% of COD, 80.39% of BOD5, 84.78% of total phosphorus (TP), 91.79% of ammonia nitrogen (NH3-N), 89.79% of nitrate nitrogen (NO3-N) and 87.14% of nitrite nitrogen (NO2-N) compared to Stigeocloniumsp. which was only able to remove 79.26% of COD, 76.27% of BOD5,75.17% of TP, 86.42% of NH3-N, 84.38% of NO3-N and 82.38 NO2-N.Conclusion, significance and impact of study:The results of this study indicate that these two species of microalgae have potential to be used in the remediation of swine manure wastewate

Simulated/ standardized patients (SPs) have become one of the significant components in today’s medical education and students’ assessment. Some differences exist in the training method of SPs for psychiatry examinations compared to other medical disciplines. This brief report highlights the challenges encountered in the training process and methods to overcome those challenges. A wellstructured, intensive training remains as one of the most important factors in ensuring standardization of SPs for psychiatric examinations.
