stereotaxy device. After one week of recovery, one microliter of the drugs was injected by a Hamilton syringe. Spatial learning and retention was measured by using the Morris water maze. FINDINGS: The results show that 12 µg/kg dose of ascorbic acid increases mileage (1012.98±63.55) and escape
The raw sewage enters into Imhoff tank which flows into pond 1 (facultative pond). From this pond, the effluent enters pond 2 which is equipped with an aeration pump. A third pond (a maturation pond; 60 × 32 ×1 m, ~10 h of retention time) from which samples were collected, receives wastewater from pond 2.
