It is shown how a general Hamiltonian can be associated with the algebra W_k. This general Hamiltonian covers various supersymmetrical versions of dynamical systems (Morse system, Poschl-Teller system, fractional supersymmetric oscillator of order k, etc.). The case of ordinary supersymmetric Quantum Mechanics corresponds to k=2. A connection between fractional supersymmetric Quantum Mechanics and ordinary supersymmetric Quantum Mechanics is briefly described. A realization of the algebra W_k, of the N=2 supercharges and of the corresponding Hamiltonian is given in terms of deformed-bosons and k-fermions as well as in terms of differential operators.

It aims at testing all pregnant women for syphilis with the help of VDLR (Venereal Disease Research Laboratory) or RPR (Rapid Plasma Reagin) tests, and in the women with positive tests to confirm the results by treponemal tests (treponemal antibodies): THPA (Treponema Pallidum Hemagglutination), FTA-Abs (Fluorescent Treponemal Antibody with Absorption), ELISA-Captia-IgM, and Western Blotting-IgM. In the pregnant women with positive tests two doses of 2.4 million units of penicillin G benzathine were administered at 5 days interval. These pregnant women are in the evidence of a specialist (obstetrician, dermatologist), and District Department of Public Health, and required to come for another serology test in 3 months. In case they still test positive, the same treatment is applied at the beginning of the third trimester of pregnancy. To assess th...

We report a 37-year old renal transplant recipient who developed infective endocarditis of the aortic valve, heart failure and renal allograft dysfunction. He underwent aortic valve replacement which was followed by improvement in cardiac as well as allograft function.

Our study concerned 42 patients collected during 5 years period, starting july 1995 until July 2000, in the dental medical service of Hedi Chaker university hospital of Sfax oriented by the cardiovascular diseases service looking for a buccodental entry of bacteria. Our patients group is divided into 25 men and 17 women of 36.1 years mean age. Dental or parodontal lesions were observed in 25 patients. Panoramic X-rays showed periapical lesions of granuloma or cystic type in 15 patients. Among the etiological factors encountered we noticed dental acts accomplished without antibioprophylaxis and dental bacterial collection medically treated without extraction. Buccodental lesions were a frequent cause of the infectious endocarditis in 59.5% of the patients studied in this report, and were due more to defectious hygienic conditions than to a disabled dental act.

In particular, we define k-fermionic coherent states and study some of their properties. The decomposition of a Q-uon into a boson and a k-fermion leads to a definition of fractional supercoherent states. Such states involve bosonic coherent states and k-fermionic coherent states. We construct an

A comparison of the results with the diffusion in the bulk specimen helps to introduce the number of diffusion sites in the surface and in the bulk. We propose then a structure of point defects in the

The ferroelectric transition with nonuniform distribution of critical temperature over a ceramic sample was found from dielectric measurements. According to X-ray diffraction measurements, the ferroelectric phase has an orthorhombic symmetry. The transition temperature was shown to decrease

The number of independent parameters for characterizing the polarization dependence is shown to depend on an ensemble of properties and rules which combine symmetry considerations and physical models.
