Gaseous and Electrochemical Hydrogen Storage Properties of Nanocrystalline Mg2Ni-Type Alloys Prepared by Melt Spinning  [PDF]
Zhihong Ma, Bo Li, Huiping Ren, Zhonghui Hou, Guofang Zhang, Yanghuan Zhang
Materials Sciences and Applications (MSA) , 2011, DOI: 10.4236/msa.2011.23018
Abstract: A partial substitution of Ni by Cu has been carried out in order to improve the hydrogen storage characteristics of the Mg2Ni-type alloys. The nanocrystalline Mg20Ni10-xCux (x = 0, 1, 2, 3, 4) alloys are synthesized by the melt-spinning technique. The structures of the as-cast and spun alloys have been characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) and high resolution transmission electron microscope (HRTEM). The electrochemical performances were evaluated by an automatic galvanostatic system. The hydrogen absorption and desorption kinetics of the alloys were determined by using an automatically controlled Sieverts apparatus. The results indicate that the substitution of Cu for Ni does not alter the major phase Mg2Ni. The Cu substitution significantly ameliorates the electrochemical hydrogen storage performances of alloys, involving both the discharge capacity and the cycle stability. The hydrogen absorption capacity of alloys has been observed to be first increase and then decrease with an increase in the Cu contents. However, the hydrogen desorption capacity of the alloys exhibit a monotonous growth with an increase in the Cu contents.

Jinliang Gao, Zhonghui Hou, Qilu Ge, Dongliang Zhao, Shihai Guo, Yanghuan Zhang
Materials Sciences and Applications (MSA) , 2010, DOI: 10.4236/msa.2010.13027
Abstract: Nanocrystalline Mg2Ni-type alloys with nominal compositions of Mg20Ni10 – xCux (x = 0, 1, 2, 3, 4) were synthesized by rapid quenching technique. The microstructures of the as-cast and quenched alloys were characterized by XRD, SEM and HRTEM. The hydrogen absorption and desorption kinetics of the alloys were measured using an automatically controlled Sieverts apparatus. The electrochemical hydrogen storage performances were tested by an automatic galvanostatic system. The results show that all the as-quenched alloys hold a typical nanocrystalline structure, and the rapid quenching does not change the major phase Mg2Ni. The hydrogen absorption and desorption capacities of the alloys significantly increase with rising quenching rate. Additionally, the rapid quenching significantly improves the electrochemical hydrogen storage capacity of the alloys, but it slightly impairs the cycle stability of the alloys.

Can Guo, Zhonghui Zou
Surgical Science (SS) , 2016, DOI: 10.4236/ss.2016.77040
Abstract: Clinical pathway (CP) is a medical management tool made by a group of medical specialists and specialized for certain diseases. It has been proved that CP was an efficient way to optimize the hospitalization management and control medical cost. In this paper, we focused on the effect of CP in the patients with acute complicated appendicitis via total duration of hospitalization, hospitalization time before operation, total cost of hospitalization and drug expenditure. From March 2014 to March 2015, the patients with conditions of appendicitis in Three Gorges Central Hospital of Wanzhou, Chongqing, were divided into CP group and non path control group to analyze the effect of the application of CP. Our data showed that there were no significant differences between two groups of patients in total duration of hospitalization, hospitalization time before operation, total cost of hospitalization and drug expenditure. The implementation of CP neither decreased the time of patients in hospital nor the total hospitalization cost. Besides, application of CP for acute appendicitis patients should distinguish between simple appendicitis and complicated appendicitis, simple appendectomy patients implement CP is beneficial, and patients with complicated appendicitis did not come from the benefit.

Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2011.2292.2296
Abstract: 4-hydroxycinnamic acid was firstly isolated from Fructus mume and identified to be one of the main components. The studies aimed to investigate the immunotherapeutic potential of 4-hydroxycinnamic acid on SPF chickens infected with IBDV. The results showed that the bird survival rate of 3 dosage groups of 4-hydroxycinnamic acid was 87.5, 62.5 and 42.86%, respectively while body weight gain rate was 25.68, 25.28 and 21.37%, respectively. As for the survival rate and body weight gain, no significant difference was found between 35 mg kg-1 dosage and high immune yolk antibody group (p>0.05). The histopathology score of the high dosage group 3 was lower than that of the high immune yolk antibody group 6. The Stimulate Index (SI) of spleen lymphocytes of chickens fed 4-hydroxycinnamic acid (SI = 1.69) was significantly higher than that of untreated chickens (SI = 1.36) (p<0.05). These results showed that chickens fed with 35 mg kg-1 4-hydroxycinnamic acid for 5 days could effectively induce a high protection against IBDV and its related mechanism may enhance cell immunity.

iBusiness (IB) , 2013, DOI: 10.4236/ib.2013.53014
Abstract: With the trend of economic globalization and localization services, employees are distributed in different regions, the old enterprise information system in closed environment has been difficult to support all the business in enterprises, also cannot meet the need of information sharing between upstream and downstream enterprises and partners in the supply chain. The new business model requires companies to have distributed information systems, remote access and other characteristics. VPN (virtual private network) is high cost and lack of flexibility, Web services-based information system can achieve low-cost real-time collection to process and share distributed information, which is the ideal model of enterprise information system. However, there is a big gap in current usability between the Web services and old desktop applications. This paper combines the usage patterns, business needs of enterprise information systems and technical characteristics of Web services, proposes the usability requirements of enterprise information systems based on Web services from different views of internal users, external customers and strategic partners.
Inflammatory Bowel Disease: Autoimmune or Immune-mediated Pathogenesis?
Zhonghui Wen,Claudio Fiocchi
Clinical and Developmental Immunology , 2004, DOI: 10.1080/17402520400004201
Abstract: The pathogenesis of Crohn's disease (CD) and ulcerative colitis (UC), the two main forms of inflammatory bowel disease (IBD), is still unclear, but both autoimmune and immune-mediated phenomena are involved. Autoimmune phenomena include the presence of serum and mucosal autoantibodies against intestinal epithelial cells in either form of IBD, and against human tropomyosin fraction five selectively in UC. In addition, perinuclear antineutrophil cytoplasmic antibodies (pANCA) are common in UC, whereas antibodies against Saccharomyces cerevisiae (ASCA) are frequently found in CD. Immune-mediate phenomena include a variety of abnormalities of humoral and cell-mediated immunity, and a generalized enhanced reactivity against intestinal bacterial antigens in both CD and UC. It is currently believed that loss of tolerance against the indigenous enteric flora is the central event in IBD pathogenesis. Various complementary factors probably contribute to the loss of tolerance to commensal bacteria in IBD. They include defects in regulatory T-cell function, excessive stimulation of mucosal dendritic cells, infections or variants of proteins critically involved in bacterial antigen recognition, such as the products of CD-associated NOD2/CARD15 mutations.
Stochastic Electron Acceleration in SNR RX J1713.7-3946

Physics , 2011,
Abstract: Stochastic acceleration of charged particles due to their interactions with plasma waves may be responsible for producing superthermal particles in a variety of astrophysical systems. This process can be described as a diffusion process in the energy space with the Fokker-Planck equation. In this paper, a time-dependent numerical code is used to solve the reduced Fokker-Planck equation involving only time and energy variables with general forms of the diffusion coefficients. We also propose a self-similar model for particle acceleration in Sedov explosions and use the TeV SNR RX J1713.7-3946 as an example to demonstrate the model characteristics. Markov Chain Monte Carlo method is utilized to constrain model parameters with observations.
