Journal of Donghua University(English Edition) 2006年第5期23卷 127-130页

作者：邢铁玲 Chu k.H. 陈国强 School of Material Engineering Soochow University Department of Chemical and Process Engineering University of Canterbury New Zealand

The sonochemical decolorization of Methylene Orange was studied using a 24 kHz Ultrasound device with a 1.4 cm diameter horn. pH, power density, the effects of pH and power density on decolorization were discussed. The combined effect of radiate time, the initial concentration of dyes and the addition of Fe^2＋ on the decolorization was studied using response surface methodology. The results showed that the factorial central composite design was successfully employed for experimental design and predication of the results. AtpH = 2.8, T=30℃, power denstity= 300 W/L and Fe^2＋ of 2 mg/L, the decolorization percentage of 5 mg/L dye solution reached 96% after 60 mill ultreatment. The rate of decolorization of the dye was greatly improved in the presence of Fe^2＋. The sonolysis of the dye followed first-order kinetics.

Removal of CO2 in a multistage fluidized bed reactor by amine impregnated activated carbon: optimization using response surface methodology

引用

International Journal of Coal Science & Technology 2019年第3期6卷 445-458页

作者： Dipa Das Sushanta k. Behera B. C. Meikap Department of Chemical Engineering Indian Institute of Technology (IIT) Kharagpur KharagpurWest Bengal 721302 India Department of Chemical Engineering School of Chemical Engineering Howard College Campus University of Kwazulu-Natal (UKZN) Durban 4041 South Africa Department of Chemical Engineering Indira Gandhi Institute of Technology (IGIT) Sarang Sarang Odisha 759146 India

Carbon dioxide (CO2) is the major component of greenhouse gas. Increase in concentration of CO2 in the atmosphere leads to global warming. To remove the CO2 from waste flue gas a four-stage counter-current multistage fluidized bed adsorber was developed and operated in continuous bubbling fluidization regime for the two丒phase system. This paper describes the optimum condition for CO2 removal efficiency in a multistage fluidized bed reactor using amine impregnated activated carbon. Response surface methodology with central composite design was used to determine the effect of three variables on the response. The variables are inlet concentration of CO2 in ppm (ranging from 3000 to 20,000), impregnation ratio of monoethanol amine (ranging from 0.2 to 0.6) and weir height in mm (20-60). The response was CO2 removal efficiency. The factor which was most influential has been identified from the analysis of variance. The optimum CO2 removal efficiency for the amine impregnated activated carbon (MEA-AC) was found to be 95.17%, at initial concentration of CO2 7312.85 ppm, chemical impregnation ratio of 0.31, and weir height 48.65 mm. From the experiment, the CO2 removal efficiency was found to be 95.97% at the same operating conditions. The predicted response was found to relevance with experimental data.

Gallbladder tuberculosis: False-positive PET diagnosis of gallbladder cancer

Gallbladder tuberculosis (GT) is an extremely rare disease, and very few cases have been reported in the literature. The first case of GT was described in 1870 by Gaucher. A correct preoperative diagnosis of GT is unusual, and it is frequently confused with various gallbladder diseases. We present a new case of a patient who underwent surgery with the preoperative diagnosis of gallbladder cancer after a false positive positron emission tomography scan in the diagnostic work-up.

用HCl或HF对Re/H-ZSM-5催化剂进行了后处理,并在50～400℃用连续流动反应器研究了催化剂对环己烯加氢转化反应的影响.与HCl处理相比,HF处理显著提高了催化剂上环己烯加氢生成环己烷以及甲基环戊烯加氢生成甲基环戊烷的催化活性,这主要是因为HF处理催化剂具有较高的铼分散度、酸中心数及酸强度.Re/H-ZSM-5(HF)催化剂上最高的酸中心强度使其具有最高的加氢裂化活性及最低的环己烯脱氢生成环己二烯活性.在未处理的Re/H-ZSM-5催化剂上,沉积在分子筛载体孔道和空穴中非骨架Al和Si的量最少,因而对生成芳烃的脱氢反应具有最高活性.卤化氢处理催化剂上二甲苯异构体的相对产量表明:HF处理催化剂上,对二甲苯产量高于间二甲苯;HCl处理催化剂上,间二甲苯和对二甲苯产量基本相当;在未处理的催化剂上,间二甲苯量产量比对二甲苯高.此外,上述所有催化剂上的邻二甲苯产量均约等于对二甲苯与间二甲苯之和.

New models to study vulvodynia: hyperinnervation and nociceptor sensitization in the female genital tract

引用

Neural Regeneration Research 2018年第12期13卷 2096-2097页

作者： Christine M.Barry kalyani k.Huilgol Rainer V.Haberberger Anatomy and Histology College of Medicine and Public Health Flinders University Centre for Neuroscience Flinders University

Vulvodynia is a prevalent form of chronic pain, most com- monly affecting the vaginal vestibule （vestibulodynia）（Pukall et al., 2016）. Women with vulvodynia describe intense pain in response to light touch of the affected region, such that sexual function and other activities can be severely limited. Medical costs associated with vulvodynia are high, exceeding $21 billion annually in the United States （Xie et al., 2012）. The high level of direct medical costs has been linked to high treatment failure rates. Many women with the disorder consult multiple practitioners and undergo multiple courses of treatment with limited benefit.
