Abstract: The wet air oxidation (WAO) and catalytic WAO (CWAO) of the high strength emulsifying wastewater containing nonionic surfactants have been investigated in terms of COD and TOC removal. The WAO and homogeneous CWAO processes were carried out at the temperature from 433 K to 513 K, with initial oxygen pressure 1.2 MPa. It was found that homogeneous catalyst copper (Cu (NO_3 )_2 ) had an fairly good catalytic activity for the WAO process, and the oxidation was catalyzed when the temperature was higher than 473 K. Moreover, several heterogeneous catalysts were proved to be effective for the WAO process. At …the temperature 473 K, after 2 h reaction, WAO process could achieve about 75% COD removal and 66% TOC removal, while catalysts Cu/Al_2 O_3 and Mn-Ce/Al_2 O_3 elevated the COD removal up to 86%–89% and that of TOC up to 82%. However, complete elimination of COD and TOC was proved to be difficult even the best non-noble catalyst was used. Therefore, the effluent from WAO or CWAO process need to be further disposed. The bioassay proved that the effluent from WAO process was amenable to the biochemical method. Show more

Abstract: Purpose: Repetitive mild traumatic brain injury (TBI) is a major military and sports health concern. The purpose of this study was to determine if a diet rich in omega-3 fatty acids would reduce cognitive deficits and neuronal cell death in a novel fluid percussion rat model of repetitive mild TBIs. Methods: Thirty-two Sprague-Dawley rats were assigned to either an experimental rat chow enhanced with 6% fish oil (source of omega-3 fatty acids) or a control rat chow. Both rat chows contained equivalent quantities of calories, oil, and nutrients. After four weeks, both groups received mild repetitive bilateral fluid percussion TBIs …on two sequential days. Pre-injury diets were resumed, and the animals were monitored for two weeks. On post-injury days 10–14, Morris Water Maze testing was performed to assess spatial learning and cognitive function. Animals were euthanized at 14 days post-injury to obtain specimens for neurohistopathology. Results: There was no difference in pre-injury weight gain between groups. Post-injury, animals on the fish oil diet lost less weight and recovered their weight significantly faster. By 14 days, the fish oil diet group performed significantly better in the Morris Water Maze. Neurohistopathology identified a non-significant trend toward a higher density of hippocampal neurons in the fish oil diet group. Conclusions: Pre-injury dietary supplementation with fish oil improves recovery of body weight and provides a small improvement in cognitive performance in a rat model of multiple mild TBIs.
