Journal of Zhejiang University-Science B(Biomedicine & Biotechnology) 2010年第3期11卷 177-189页

A treatability study of industrial wastewater containing chlorinated nitroaromatic compounds （CNACs） by a catalytic ozonation process （COP） with a modified Mn/Co ceramic catalyst and an aerobic sequencing batch reactor （SBR） was investigated. A preliminary attempt to treat the diluted wastewater with a single SBR resulted in ineffective removal of the color, ammonia, total organic carbon （TOC） and chemical oxygen demand （COD）. Next, COP was applied as a pretreatment in order to obtain a bio-compatible wastewater for SBR treatment in a second step. The effectiveness of the COP pretreatment was assessed by evaluating wastewater biodegradability enhancement （the ratio of biology oxygen demand after 5 d （BOD5） to COD）, as well as monitoring the evolution of TOC, carbon oxidation state （COS）, average oxidation state （AOS）, color, and major pollutant concentrations with reaction time. In the COP, the catalyst preserved its catalytic properties even after 70 reuse cycles, exhibiting good durability and stability. The performance of SBR to treat COP effluent was also examined. At an organic loading rate of 2.0 kg COD/（m^3.d）, with hydraulic retention time （HRT）=10 h and temperature （30±2） ℃, the average removal efficiencies of NH3-N, COD, BOD5, TOC, and color in a coupled COP/SBR process were about 80%, 95.8%, 93.8%, 97.6% and 99.3%, respectively, with average effluent concentrations of 10 mg/L, 128 mg/L, 27.5 mg/L, 25.0 mg/L, and 20 multiples, respectively, which were all consistent with the national standards for secondary discharge of industrial wastewater into a public sewerage system （GB 8978-1996）. The results indicated that the coupling of COP with a biological process was proved to be a technically and economically effective method for treating industrial wastewater containing recalcitrant CNACs.

Unveiling the charge density wave inhomogeneity and pseudogap state in 1T-TiSe_2

引用

Science Bulletin 2018年第7期63卷 426-432页

作者： Kai-Wen Zhang Chao-Long Yang Bin Lei Pengchao Lu xiang-bing li Zhen-Yu Jia Ye-Heng Song Jian Sun Xianhui Chen Jian-Xin li Shao-Chun li National Laboratory of Solid State Microstructures School of Physics Nanjing University Hefei National Laboratory for Physical Science at Microscale and Department of Physics University of Science and Technology of China Collaborative Innovation Center of Advanced Microstructures Nanjing University

By using scanning tunneling microscopy(STM)/spectroscopy(STS), we systematically characterize the electronic structure of lightly doped 1 T-TiSe_2, and demonstrate the existence of the electronic inhomogeneity and the pseudogap state. It is found that the intercalation induced lattice distortion impacts the local band structure and reduce the size of the charge density wave(CDW) gap with the persisted 2 × 2 spatial modulation. On the other hand, the delocalized doping electrons promote the formation of pseudogap. Domination by either of the two effects results in the separation of two characteristic regions in real space, exhibiting rather different electronic structures. Further doping electrons to the surface confirms that the pseudogap may be the precursor for the superconducting gap. This study suggests that the competition of local lattice distortion and the delocalized doping effect contribute to the complicated relationship between charge density wave and superconductivity for intercalated 1 T-TiSe_2.

Role of tissue factor in hepatocellular carcinoma genesis, invasion and metastasis

Chinese Medical Journal 2011年第22期124卷 3746-3751页

作者： ZHOU Qi HUANG Tao WANG Ya-feng ZHOU xiang-bing liANG li-jian PENG Bao-gang Department of Hepatobiliary Surgery First Affiliated Hospital of Sun Yat-Sen University Guangzhou Guangdong 510080 China

Background Numerous studies indicate that tissue factor （TF）, namely tissue thromboplastin, has a close relationship with malignant tumor genesis and progress. It contributes to blood coagulation as well as the regulation of cellular differentiation, the formation of blood vessels, and also tumor recurrence and metastasis. The present study aimed to detect TF expression in hepatocellular carcinoma （HCC） patients and to elucidate its association with prognosis and clinical features of the disease. Methods The plasma TF levels of 50 HCC patients and 30 controls were assayed by EliSA. The expressions of TF mRNA and protein in HCC tissues, adjacent tissues and normal tissues were detected by reverse transcription- polymerase chain reaction （RT-PCR） and Western blotting. The acquired data were analyzed with related clinic-pathological documents. The patients were followed up for five years, and the relationship between TF and prognosis was analyzed. Results The plasma TF levels were significantly increased in HCC compared to the controls （P 〈0.05）, presenting a close relationship with differentiation level, tumor size and hepatocirrhosis occurrence （P 〈0.05）. There were remarkably higher values in cases of lymphatic metastasis, extrahepatic metastasis and portal tumor thrombus （PTT）（P 〈0.05） compared to non-metastasis or non-tumor thrombus, but no significant difference with different focus number or envelope （P 〉0.05）. The positive rates and the relative expression of TF mRNA in HCC tissue were 63.0% （17/27） and 0.567±0.268, respectively, significantly higher than that in adjacent tissues or normal tissues （P 〈0.05）. In the patients with positive results, the relative expression intensity varied significantly with different tumor size and index of local invasion and metastasis （P 〈0.05）. The positive rates and the relative expression intensities of TF protein in HCC tissue were 74.1% （20/27） and 4.093±1.256, respectively, significantly higher than those in adjacent tis

企业外源融资结构主要取决于对经营决策具有决定作用的经理层的主观能动性,而经理层能动性受到客观存在的融资风险引发的自身利益损失和职位被替换等防御动机的影响。本文以GONE理论为基础分析了经理层管理防御影响企业外源融资结构的机理,并以我国上市公司为研究对象实证研究经理层管理防御水平强弱与企业外源融资结构的内在关系,进一步考察股权激励对两者关系的调节作用。研究发现:经理层管理防御是企业外源融资结构的主要影响因素,而股权激励能够弱化经理层管理防御对企业外源融资结构的不利影响,发挥对债权融资比向上的调节作用和对股权融资比、长期债务比向下的调节作用。因此,企业应重视运用经理层股权激励对经理层管理防御动机下外源融资结构偏好的调节作用。研究结论可为企业外源融资结构设计提供参考,为弱化经理层管理防御强度以形成合理的外源融资结构提供借鉴。
