Guangxia QI, Dongbei YUE, Yongfeng NIE

Frontiers of Environmental Science & Engineering 2012, Volume 6, Issue 5,   Pages 711-716 doi: 10.1007/s11783-012-0421-z

Abstract: Considerable organic matter remains in municipal solid waste landfill leachate after biological treatmentsHumic substances (HSs) dominate the organic matter in bio-treated landfill leachate.In this study, the HSs from landfill leachate treated by membrane bioreactor (MBR-HSs) were analyzedaromatic carbon content of MBR-HSs was lower than that of humus-derived HSs but higher than that of waste-derivedHSs, indicating that MBR-HSs appeared to be more similar to humus-derived HSs than waste-derived HA.

hydrogen production in microbial electrolysis through strategies of carbon recovery from alkaline/thermal treated

Ling Wang, Chunxue Yang, Sangeetha Thangavel, Zechong Guo, Chuan Chen, Aijie Wang, Wenzong Liu

Frontiers of Environmental Science & Engineering 2021, Volume 15, Issue 4, doi: 10.1007/s11783-020-1348-4

Abstract: Abstract • High hydrogen yield is recovered from thermal-alkaline pretreated sludge. • Separating SFL by centrifugation is better than filtration for hydrogen recovery. • The cascaded bioconversion of complex substrates in MECs are studied. • Energy and electron efficiency related to substrate conversion are evaluated. The aim of this study was to investigate the biohydrogen production from thermal (T), alkaline (A) or thermal-alkaline (TA) pretreated sludge fermentation liquid (SFL) in a microbial electrolysis cells (MECs) without buffer addition. Highest hydrogen yield of 36.87±4.36 mgH2/gVSS (0.026 m3/kg COD) was achieved in TA pretreated SFL separated by centrifugation, which was 5.12, 2.35 and 43.25 times higher than that of individual alkaline, thermal pretreatment and raw sludge, respectively. Separating SFL from sludge by centrifugation eliminated the negative effects of particulate matters, was more conducive for hydrogen production than filtration. The accumulated short chain fatty acid (SCFAs) after pretreatments were the main substrates for MEC hydrogen production. The maximum utilization ratio of acetic acid, propionic acid and n-butyric acid was 93.69%, 90.72% and 91.85%, respectively. These results revealed that pretreated WAS was highly efficient to stimulate the accumulation of SCFAs. And the characteristics and cascade bioconversion of complex substrates were the main factor that determined the energy efficiency and hydrogen conversion rate of MECs.

Improved local control without elective nodal radiotherapy in patients with unresectable NSCLC treated

YANG Kunyu, LIU Li, ZHANG Tao, WU Gang, CAO Fengjun, WANG Jianhua

Frontiers of Medicine 2007, Volume 1, Issue 4,   Pages 381-385 doi: 10.1007/s11684-007-0074-7

Abstract: To investigate the influence of prophylactic elective nodal irradiation on the therapeutic results of definitive radiotherapy for patients with stage IIIA or stage IIIB unresectable non-small-cell lung cancer, 55 patients with clinically inoperable advanced non-small-cell lung cancer were studied. After four cycles of induction chemotherapy, the patients were divided into two groups at random. In one group, the elective nodal irradiation was included in clinical tumor volume (CTV) of definitive radiotherapy (ENI group); and in the other group, elective nodal irradiation was not included in CTV (non-ENI group). For the patients in the ENI group, the mean prescription dose for gross tumor volumes was 58.4 Gy, while for the patients in the non-ENI group, it was 65.8 Gy (<0.05). The responsive rates were 45.8% and 74.0% (<0.05), and the rate of the elective nodal failure (ENF) was 4.2% and 11.1%, respectively. Kaplan-Meier analysis showed that the mean local-progression-free survival time was 11.0 and 15.0 months, and one-year local-failure rates were 51.9% and 24.5% (<0.05). The median overall survival time was 13.0 and 15.0 months, respectively ( = 0.084). The one-year survival rates were 55.7% and 72.5%, and two-year survival rates were 0% and 19.9%. There was no significant difference in the occurrences of radiation-associated complications between the two groups. Our results showed that omitting elective nodal irradiation did not result in a high incidence of elective nodal failure. On the contrary, it decreased local failure by increasing prescription doses to the primary diseases and lymphadenopaphy, and thereby it may further prolong the patients survival.
