In studies of congestive heart failure (CHF) treatment, it is essential to select animals with a similar degree of cardiac dysfunction. However, this is difficult to establish without hemodynamic evaluation in rat postinfarction-induced CHF. This study aimed to diagnose CHF in long-term follow-up postinfarction rats using only echocardiographic criteria through a J-tree cluster analysis and Fis...

statement of the problem: vertical root fractures are catastrophic events that often result in tooth extraction. many contributing factor are associated with increasing incidence of vertical root fracture. root canal preparation is one of the predisposing factors which can increase the root susceptibility to vertical fracture. purpose: the aim of this study was to compare the effects of three d...

nowadays nmr spectroscopy becomes a powerful tool in chemistry because of the nmr chemical shifts. hartree–fock theory and the gauge-including atomic orbital (giao) methods are used in the calculation of 29si nmr chemical shifts of various silicate species in the silicate solution as initial components for zeolite synthesis both in gas and solution phase. calculations have been performed at geo...

We first review some recent developments [2] of the N -wave equations and their gauge equivalent ones related to the so(5) algebra. These include the form of the equations and the relevant recursion operators, the properties of the scattering data etc. Next we generalize these results to the multicomponent nonlinear Schrödinger equations and their gauge equivalent ones known as the Heisenberg f...

We present results for response functions and asymmetries in the nuclear reactions 37 Ar(e, e ′ n) 36 Ar and 37 K(e, e ′ p) 36 Ar at quasifree kine-matics. We compare PWIA results obtained using deformed HF wave functions with PWIA and DWIA results obtained assuming a spherical mean field. We show that the complex structure of the deformed orbitals can be probed by coincidence measurements with...

The study investigated whether a persistent impairment of insulin secretion resulting from mild protein restriction predisposes to loss of glucoregulatory control and impaired insulin action after the subsequent imposition of the diabetogenic challenge of high-fat feeding. Offspring of dams provided with either control (20% protein) diet (C) or an isocaloric restricted (8%) protein diet (PR) we...

The Thouless instability conditions in the binuclear iron complex 1 have been investigated by means of a semiempirical INDO approach. The behaviour of the restricted Hartree-Fock (HF) wave function with respect to singlet, non-singlet and complex variations of the orbitals is studied. The existence of a spin decoupled solution near the diamagnetic closed shell groundstate is demonstrated. The n...

HF radar can be employed to measure sea surface state parameters such as waveheight, wind field and surface current velocity. This paper describes the application of the high frequency ground wave radar in remote sensing the surface conditions over the Eastern China Sea in October, 2000. The radar, referred to as the OSMAR2000, was developed by Wuhan University. Preliminary wave spectra, wavehe...
