The combustion energy has been determined for the nine solid complexes of rare earth perchlorate with glycine and imidazole using a rotatingbomb *** standard enthalpy of combustion,H0 -c,coor(s), and standard enthalpy of formation,H0 -f,coor(s), for these complexes have been calculated. From the plot of standard enthalpy of formation versus atomic number of the elements in lanthanide series the tripartite effect regularity was observed and the unknown standard enthalpy of formation for similar complexes,Ce(Gly)4(Im)(ClO4)32H2O and Pm(Gly)4(Im)(ClO4)32H2O,can be estimated according to the figure.

A new hybrid coupled model(HCM) is presented in this study, which consists of an intermediate tropical Pacific Ocean model and a global atmospheric general circulation model. The ocean component is the intermediate ocean model(IOM)of the intermediate coupled model(ICM) used at the Institute of Oceanology, Chinese Academy of Sciences(IOCAS). The atmospheric component is ECHAM5, the fifth version of the Max Planck Institute for Meteorology atmospheric general circulation model. The HCM integrates its atmospheric and oceanic components by using an anomaly coupling strategy. A100-year simulation has been made with the HCM and its simulation skills are evaluated, including the interannual variability of SST over the tropical Pacific and the ENSO-related responses of the global atmosphere. The model shows irregular occurrence of ENSO events with a spectral range between two and five years. The amplitude and lifetime of ENSO events and the annual phase-locking of SST anomalies are also reproduced realistically. Despite the slightly stronger variance of SST anomalies over the central Pacific than observed in the HCM, the patterns of atmospheric anomalies related to ENSO,such as sea level pressure, temperature and precipitation, are in broad agreement with observations. Therefore, this model can not only simulate the ENSO variability, but also reproduce the global atmospheric variability associated with ENSO, thereby providing a useful modeling tool for ENSO studies. Further model applications of ENSO modulations by ocean–atmosphere processes, and of ENSO-related climate prediction, are also discussed.

Fishbones are the most commonly ingested foreign bodies that cause gastrointestinal tract penetration. However, fishbones embedded in the gastrointestinal tract that lead to foreign body granulomas that mimic submucosal tumors are rare. Herein, we describe a 56-year-old woman who presented with a 20-day-history of upper abdominal pain. Endoscopy revealed an elevated lesion in the gastric antrum. An abdominal computed tomography scan showed a mass in the gastric antrum and a linear calcified lesion in the mass. An endoscopic ultrasonography examination revealed a 3.9 cm × 2.2 cm, irregular, hypoechoic mass with indistinct margins in the muscularis propria layer. The patient was initially diagnosed as having a submucosal tumor, and subsequent surgical resection showed that the lesion was a foreign body granuloma caused by an embedded fishbone. Our case indicated that the differential diagnosis of a foreign body granuloma should be considered in cases of elevated lesions in the gastrointestinal tract.

Singular Quasilinear Elliptic Problems with Indefinite Weights and Critical Potential

In order to solve the problem that there is coupling among neutral current and three phase current in the model of three-level PWM rectifier, this thesis has introduced the idea of coordinate transformation to transform the model from three-phase stationary coordinate system to two-phase rotating coordinate system, which reduces the order of the system to four- order linear compact model, according to the principles of grid voltage vector orientation. Based on strategy analysis of the control of three-level rectifier, we have made the solution that design the structure of the rectifier system into the double closed-loop which is consist of voltage loop and current loop, realizing the purpose that the power factor of AC side keeps 1 and the voltage of DC side keeps stability. With completing the decoupling of the state feedback of current, this thesis has designed the inner current controller and the outer voltage controller respectively, according to the engineering design methods of making atypical system typical. For dealing with the problems of DC bus voltage disturbance caused by load current, we have introduced the feed-forward compensator to improve the anti-jamming performance of the system. Finally, the results of Matlab simulation have proved that the designed three-level PWM rectifier system has good dynamic indicators and anti-interference ability.

The Dirichlet problem for a quasilinear sub-critical inhomogeneous elliptic equation with critical potential and singular coefficients, which has indefinite weights in RN, is studied in this paper. We discuss the corresponding eigenvalue problems by the variational techniques and Picone＇s identity, and obtain the existence of non-trivial solutions for the inhomogeneous Dirichlet problem by using Hardy inequality, Mountain Pass Lemma in conjunction with the property of eigenvalues.

Based on the approach of biorthogonal basis, we carry out the quasinormal modes （QNMs） expansions for a class of open systems described by the wave equation with outgoing wave boundary conditions. For such a non-Hermitian system, the eigenfunction perturbation expansions and Green function method, which are based on the orthogonal eigenvectors of the Hermitian Hamiltonian for the dosed quantum system, can be generalized in terms of the biorthogonal basis, the two sets of eigenfunctions of H and its adjointness H . The time-independent perturbation theory for the complex frequencies can be also developed.
