Abstract: Active barrier system (ABS) capping zeolite with large surface area and strong adsorption ability is an effective way to control eutrophication of lake since it can remove ammonia in the lake released by sediment. Influence of the initial nitrogen concentration on eliminating nitrogen load of europhia sediment capping with active barrier system (ABS) were studied through an investigation of the repairment results of serious pollution period (total nitrogen concentration up to 25.33 mg/L), moderate pollution period (14.39 mg/L) and the slight pollution period (3.47 mg/L) of the ancient Canal of Yangzhou. The results showed that: (1) zeolite F1 inhibition effect is stronger than zeolite F2. More TN were removed as the initial TN concentration increased and longer rapid inhibit period were presented with the increased initial TN concentration. (2) The ammonia nitrogen in sediment could be rapidly released into the overlying water, and with lower initial TN concentration in source water, more ammonia would be released from the sediment. Long time treatment was necessary to inhibit the release of ammonia completely if the water showed a high initial TN concentration. (3) After covering zeolite, the total nitrogen in the overlying water were removed mainly through nitrification and denitrification. At the initial TN concentration of 3.47 mg/L, 14.39 mg/L, 25.88 mg/L, 61%, 45% and 52% of TN were removed by the conversion of ammonia to nitrogen gas, however, others left in water as nitrate nitrogen and nitrite residues, and 90% was nitrate nitrogen.

Purpose For patients with stage II to IV laryngeal cancer, radiation therapy (RT) either alone or with concurrent chemotherapy provides the highest rate of organ preservation but can be associated with functional impairment. Thus, we studied the use of induction chemotherapy with or without conservation laryngeal surgery (CLS). Our objectives were to study the sensitivity of laryngeal cancer to platinum-based chemotherapy alone and to highlight the efficacy of CLS in this setting. Patients and Methods Thirty-one previously untreated patients with laryngeal cancer (T2-4, N0-1, M0), who were resectable with CLS, were enrolled. Patients received three to four cycles of paclitaxel, ifosfamide, and cisplatin (TIP) chemotherapy, and response was assessed histologically. Patients with partial response (PR) proceeded to CLS. Patients achieving pathologic complete response (pCR) received an additional three cycles of TIP and no other treatment. Results Thirty patients were assessable for response. With TIP chemotherapy alone, 11 patients (37%) achieved pCR, 10 of whom (33%) remain alive with durable disease remission and no evidence of recurrence over a median follow-up time of 5 years. Nineteen patients (63%) treated with TIP alone achieved PR. The overall laryngeal preservation (LP) rate was 83%, and only five patients (16%) required postoperative RT. No patient required a gastrostomy tube or tracheotomy. Conclusion Chemotherapy alone in selected patients with T2-4, N0-1 laryngeal cancer can provide durable disease remission at 5 years. For patients with PR, CLS provides a high rate of LP. This prospective study suggests that chemotherapy alone may cure selected patients with laryngeal cancer, warranting further prospective investigation.

This research was conducted to study the potential of the plants ‘useless’ as kiambang(Salvinia natans) which are easy to find, and not as valuable as textile dyeing waste handlingmedia. Treatment technique used is to replace the growth medium with the waste in questionin this case of waste taken in the dyeing industry. The concentration of methylene blueinwaste of  dye, and congo red, before and after treatment, determined by spectrophotometry.Fluid absorbance was measured at a wavelength of 664 nm for methylene blue and 496 nmfor congo red. Long time treatment used is 6, 12, 18, 24, 30, 36, and 48 hours. These resultsindicate that kiambang (Salvinia natans) is useful to lower BOD and COD of waste dyeing,although its ability to reduce the content of the dye congo red and blue methyl insignificant.This may be caused by too concentrated the dyeing waste.
