Controllable Hydrothermal Synthesis of MnO2 Nanostructures  [PDF]
Jianghong Wu, Hongliang Huang, Li Yu, Junqing Hu
Advances in Materials Physics and Chemistry (AMPC) , 2013, DOI: 10.4236/ampc.2013.33029
Abstract: Various MnO2 nanostructures with controlling phases and morphologies, like α-MnO2 nanorods, nanotubes, nanocubes, nanowires and β-MnO2 cylinder/spindle-like nanosticks have been successfully prepared by hydrothermal method, which is simply tuned by changing the ratio of Mn precursor solution to HCl, Mn(Ac)2·4H2O or C6H12O6·H2O, surfactants and reaction temperature and time. The study found out that temperature is a crucial key to get a uniform and surface-smooth nanorod. High ratio of KMnO4 to HCl leads to well dispersed MnO2 nanorods and changing the precursor of HCl into Mn(Ac)2·4H2O or C6H12O6·H

Prevalence and Factors of Addictive Internet Use among Adolescents in Wuhan, China: Interactions of Parental Relationship with Age and Hyperactivity-Impulsivity
Xianhua Wu, Xinguang Chen, Juan Han, Heng Meng, Jianghong Luo, Liesl Nydegger, Hanrong Wu
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0061782
Abstract: Purposes This study examined the prevalence of addictive Internet use and analyzed the role of parental relationship in affecting this behavior among a random sample of adolescents in Wuhan, China. Methods Students (n = 1,101) were randomly selected from four schools, including 638 boys and 463 girls with a mean age of 13.8 (standard deviation = 1.2) years. Addictive Internet use, parental relationship, hyperactivity-impulsivity were measured by validated instruments. Prevalence rate, ANOVA and multiple linear regression method were used to analyze the level of Internet addiction and its association with parental relationship, hyperactivity-impulsivity, as well as the interaction of parental relationship with chronological age and hyperactivity-impulsivity. Results The prevalence rate of Internet addiction was 13.5% (16.5% for boys and 9.5% for girls, p<0.01). Compared to non-addictive users, addictive Internet users were scored significantly lower on parental relationships and significantly higher on hyperactivity-impulsivity. Interaction analysis indicated that better parental relationship was associated with more reductions in risk of addictive Internet use for younger students than for older students, and with more risk of Internet addiction among higher than among lower hyperactivity-impulsivity students. Conclusions Findings of this study indicate that adolescent addictive Internet use is a significant public health threat in China. Prevention interventions targeting parental relationship must consider adolescent’s age and hyperactivity-impulsivity tendency.
On Party Politics in Early Republic of China and Modern Political Civilization
Jianghong Xu
Journal of Politics and Law , 2009, DOI: 10.5539/jpl.v1n4p57
Abstract: A tide of party foundation and activity appears in early Republic of China. During this period, party politics differs from that in western capitalism countries in its growth and decline, which is derived from China’s special economic and political features after the 1911 revolution. By studying the growth and decline history of parties in early Republic of China, we find that: the fundamental problem of party politics in early Republic of China is that parties can not satisfy the requirements of modern political civilization.
A cellular automata model for simulating activated sludge wastewater treatment processes

CHEN Qingcai,SHI Jianghong,WU Wei,

环境科学学报 , 2011,
Abstract: In this study, a two-dimensional cellar automata model was developed to simulate activated sludge wastewater treatment processes. The results show that the model was successful in dynamic visualization of wastewater treatment processes, in simulation of adsorption and degradation of organic matter, and in simulation of the growth and decay of activated sludge biomass. The sludge particle size, molecular radii of organic substrates, the temperature and the sludge concentration had significant influences on the simulation results. The sensitivity analysis indicates that the particle size may be the most important factor in the initial stage of the adsorption process, while the temperature be the major factor controlling the metabolic rate of activated sludge biomass. These findings are consistent with the existing theories. The cellar automata model will lead to a better understanding of the wastewater treatment processes, and thus provide theory-based design principles and guidelines for treatment systems.
Dynamic Impact of Interest Rate Policy on Real Estate Market
Jianghong Zhang,Wenkuan Chen
Asian Social Science , 2011, DOI: 10.5539/ass.v7n10p188
Abstract: The purpose of this paper is to analyze the dynamic impact of Interest Rate Policy on the Real Estate Market. In this paper we constructed a vector autoregression (VAR) model using five indicators and analyzed the response of the real estate market to the impulse of interest rate policy based on the monthly data from January 2003 to September 2010 in China. The results show that the Central Bank Reserve Ratio has a negative impact on the real estate market from a long-term perspective; and the lags of interest rate policy effect is longer, while action period is shorter from a short-term perspective. So we consider that the Interest Rate Policy does not play a significant role in the regulation of real estate market in this paper.

Advances in Bioscience and Biotechnology (ABB) , 2018, DOI: 10.4236/abb.2018.99030
Abstract: This study aims to evaluate the preventive effects of anthocyanins extracts (MAEs) from mulberry variety PR-01 against N-nitrosodiethylamine (NDEA)-induced hepatocarcinogenesis in rats. It was found that 150 mg·kg-1 MAEs treatment significantly reduced the NDEA-induced hepatic nodules incidence and hepatocellular carcinoma incidence by 58.30% and 41.70% compared to the model group. Meanwhile, MAEs significantly restored the elevated the liver function enzymes, inhibited the tumor necrosis factor alpha and interleukin-6 levels, elevated the serum interleukin-10 and interferon-γ and increased hepatic glutathione-S-transferase and UDP-glucuronosyltransferase 2B1 enzyme activity. Moreover, 150 mg·kg-1 MAEs supplement enhanced glutathione content and the activities of superoxide dismutase, catalase, glutathione peroxidase activities but reduced the malondialdehyde and thiobarbituric acid-reactive substances content by 37.90% and 44.52%. Furthermore, MAEs pretreatment maintained nuclear factor erythroid 2-related factor 2 (Nrf2), Kelch-like ECH-associated protein 1, heme oxygenase-1, and NAD(P)H: quinine oxidoreductase1 stimulation and inhibited the expression of TNF-α, nuclear factor-kappaB (NF-κB), and cyclooxygenase-2 (COX-2), indicating that MAEs exhibit effectively prevention effects against liver cancer via decreased lipid peroxidation, induced Nrf2-mediated antioxidant enzymes and attenuating the inflammatory mediators COX-2 through NF-κB pathway. Thus, MAEs of mulberry variety

Technology for Improving Life of Thermal Recovery Well Casing
TANG Zhijun,ZHOU Yanjun,JIA Jianghong
Advances in Petroleum Exploration and Development , 2013, DOI: 10.3968/j.aped.1925543820130501.1136
Abstract: In steam injection process, casing is heated by steam, the change of casing temperature produces thermal stresses in the casing, the casing deforms when stresses exceed the yield point of its material. Casing failure is becoming increasingly prominent in thermal recovery wells, which severely restricts the development effect of such reservoirs, improving casing life of thermal recovery well has become a urgent problem to be solved. Through on-site survey and analysis, reasons for casing damage were determined as follows: strength change by high temperature, sand flow over of oil formation, poor cementing, unfavorable heat insulation and bad material for casing. In order to improve casing life, the supporting measures are introduced, the measures include pre-stress cementing technology, using casing head, thermal stress compensator, high-performance insulation tubing, high temperature cement slurry system, FRT110H special casing, and early sand control completion technology. Field application of these measures has gotten better effect in Shengli oilfield in recent years, the damage rate of thermal recovery well has decreased obviously, and this can provide reference for the efficient development of similar reservoirs at home and abroad. Key words: Casing failure; Thermal recovery wells; Special casing; Cementing; Sand control completion
