Phase Relations in Si-Al-Y-O-C Systems  [PDF]
Kan Wu, Laner Wu, Zhenkun Huang, Yong Jiang, Yun Ma
Journal of Materials Science and Chemical Engineering (MSCE) , 2015, DOI: 10.4236/msce.2015.37011
Abstract:

The present work investigated the phase relations in SiC-Al2O3-Y2O3-SiO2 (Si-Al-Y-O-C) system. As a continuation of our previous works, the purpose of this study is to understand the high temperature reaction behaviors of SiO2 in the system and its effect on the phase relations of the valuable system of SiC-Al2O3-Y2O3. The phase compositions of six solid-state reacted samples with different components of Y2O3:Al2O3:SiC:SiO2 were analyzed by XRD. The phase relations of the systems were determined. The subsolidus phase diagrams of ternary Al2O3-SiC-SiO2 system and the tentative phase diagram of an extended quaternary Y2O3-Al2O3-SiC-SiO2 system were presented latter involving several coexisting regions of four phases. The high temperature reaction behavior of SiO2 in the system and its effect on the phase relations of system were discussed.

Slide Pharyngo-Esophagostomy Following Ablation of Hypopharyngeal Cancer  [PDF]
Ming-Ho Wu, Han-Yun Wu
Surgical Science (SS) , 2017, DOI: 10.4236/ss.2017.89043
Abstract: We describe a procedure of slide pharyngo-esophagoplasty for restoration following ablation of hypopharyngeal cancer in a 99 year-old man. The elderly presented to our hospital with 2-month dysphagia, occasional bloody salivation, and 2-day respiratory distress. To solve the problems of swallowing difficulty and dyspnea, he underwent laryngopharyngectomy, permanent tracheostomy, and slide pharyngo-esophagoplasty. The patient was uneventful after the restoration procedure.

International Journal of Mathematics and Mathematical Sciences , 2001, DOI: 10.1155/s0161171201006603
Abstract: We evaluate sums of certain classes of new series involving the Riemann zeta function by using the theory of the double gamma function and a property of the gamma function. Relevant connections with various known results are also pointed out.
Wuthering Heights—the Song of Rebel
Cai-yun WU
Studies in Literature and Language , 2010,
Abstract: Wuthering heights is the masterpiece by Emily Bronte. This paper aims to analyze the rebellious spirit in this novel. Almost every character in this novel is filled with rebellious spirit. The author will first analyze the protagonists’ rebellion. Then the minor characters’ rebellion will also be talked about. They rebel against different people. However, to some extent, they are rebelling against the society, the moral system, the authority and so on. During their life journey, they are pursuing the self. Several questions will be answered in this thesis: What are they rebelling for? Why do they want to rebel? What do they get from their rebellion? What does the author want to express through this novel? The thesis systematically presents the character’s rebelling behaviors and the causes; it even tries to probe into the influence of Emily Bronte’s personality on this novel. This paper will, to some degree, widen the research area. Key words: Wuthering Heights; rebel; feminism

Abstract: The structure of the title compound, C16H14O2, contains one half-molecule in the asymmetric unit and the molecule is located on a mirror plane. The dihedral angle between the two benzene ring planes is 53.07 (6)°. The crystal structure involves intermolecular C—H...O hydrogen bonds.
A Decision Support System for Borrower’s Loan in P2P Lending
Jinghua Wu,Yun Xu
Journal of Computers , 2011, DOI: 10.4304/jcp.6.6.1183-1190
Abstract: Recently, P2P lending has become a hot research topic in finance, especially after the global financial crisis. Most existing research did not consider the efficiency from the borrowers’ perspective. This paper proposes a decision support system based on intelligent agents in P2P Lending for borrowers. The system provides borrowers with individual risk assessment, eligible lender search, lending combination and loan recommendation. The system is developed in JADE and evaluated with the PROSPER’s sample data. The result shows that, the model can meet borrower’s needs better and help borrower getting loan more efficiently. Furthermore, it contributes to finance industry by accelerating the funds flow and does favor to economic recovery.

Bifurcation Phenomena of Nonlinear Waves in a Generalized Zakharov-Kuznetsov Equation
Yun Wu,Zhengrong Liu
Advances in Mathematical Physics , 2013, DOI: 10.1155/2013/812120
Abstract: We study the bifurcation phenomena of nonlinear waves described by a generalized Zakharov-Kuznetsov equation . We reveal four kinds of interesting bifurcation phenomena. The first kind is that the low-kink waves can be bifurcated from the symmetric solitary waves, the 1-blow-up waves, the tall-kink waves, and the antisymmetric solitary waves. The second kind is that the 1-blow-up waves can be bifurcated from the periodic-blow-up waves, the symmetric solitary waves, and the 2-blow-up waves. The third kind is that the periodic-blow-up waves can be bifurcated from the symmetric periodic waves. The fourth kind is that the tall-kink waves can be bifurcated from the symmetric periodic waves. 1. Introduction and Preliminary Zakharov-Kuznetsov (Z-K) equation [1], was first derived for describing weakly nonlinear ion-acoustic wave in a strongly magnetized lossless plasma in two dimensions. The Z-K equation governs the behavior of weakly nonlinear ion-acoustic waves in a plasma comprising cold ions and hot isothermal electrons in the presence of a uniform magnetic field [2, 3]. There are lots of research for various generalized Z-K equations [4–13]. For the Z-K equation Yan and Liu [4] gave some polynomial solutions, triangular function solutions and elliptic periodic solutions, of (2) via a direct symmetry method. When , , and , equation (2) reduces to Bekir [5] used the -expansion method to obtain three types of traveling wave solutions of (3). For the generalized Zakharov-Kuznetsov equation where , , , and are real constants, Song and Cai [6] got some solitary wave and kink wave solutions of (4). When , Zhang [7] used the new generalized algebraic method to obtain some soliton solutions, combined soliton solutions, triangular periodic solutions, Jacobi elliptic function solutions, combined Jacobi elliptic function solutions, and rational function solutions of (4). Biswas and Zerrad [8] obtained 1-soliton solution of (4) with dual-power law nonlinearity. When , Liu and Yan [9] obtained some common expressions and two kinds of bifurcation phenomena for nonlinear waves of (4). Meanwhile, they pointed out that there are two sets of kink waves which are called tall-kink waves and low-kink waves, respectively. In order to investigate the bifurcation phenomena of (4), letting be wave speed and substituting with into (4), it follows that Integrating (5), we get Setting ; yields the following planar system: Obviously, system (7) is a Hamiltonian system with Hamiltonian function where is the integral constant. Let On parametric plane, let represent the following four

Abstract: 通过调节系统pH对餐厨垃圾厌氧消化酸化产物进行实验研究的结果表明,当pH为4~5时,酸化产物中乙酸占总酸累积浓度的59.83%,丙酸所占比例最低,仅为3.94%,酸化产物组成最合理,对后续产甲烷过程有利,但此时,酸化产物累积量少,酸化效率低。实验结果表明,采用热碱预处理和控制系统pH相结合的方法能够同时提高餐厨垃圾厌氧消化酸化效率和优化酸化产物组成,该方法使总VFAs累积浓度提高了68%,且酸化产物组成合理。扫描电镜的微观分析结果显示,经热碱预处理的餐厨垃圾微观结构发生了明显改变,动力学分析结果也表明,经热碱预处理后的餐厨垃圾较未经处理的餐厨垃圾厌氧产酸速度更快。
