Abstract: Synthesis and magnetic properties study of solids solutions (Bi1.524–x M x Cu0.476)[Sb1.524Cu0.476]O7+δ with M=Ca et Pb. The solid solutions with pyrochlore-like structure and general chemical formula (Bi1.524–x M x Cu0.476)[Sb1.524Cu0.476]O7+δ (M= Ca2+, Pb2+) have been synthesized by solid-state chemical reaction at high temperature. The two solutions crystallize in the cubic system, with Fd m space group. Domains of homogeneity are 0≤ x ≤0.30 and 0≤ x ≤0.26 for calcium and lead, respectively. A regular decreasing of the cell parameter has been observed in the calcium solid solution. The state oxidation +5 of antimony has been put in evidence by the Mössbauer spectrometry of 121Sb. Magnetic susceptibility measurements showed that the effective magnetic moment of copper in these compounds decreases when bismuth is substituted for calcium. To cite this article: M.

Abstract: Synthesis and structural determination by the Rietveld method of a new compound with pyrochlore-like structure (Bi1.524Cu0.476)(Sb1.524Cu0.476)O7+δ . A new polycristalline compound with pyrochlore-like structure and chemical formula (Bi1,524Cu0,476)(Sb1,524Cu0,476)O7+δ has been synthesized using the classical solid-state reaction method. The Rietveld structure determination shows that the cubic cell parameter is a =10.430(1) Å and the space group Fd m with eight formula units per cell. The reliability factors are R p =7.1; R wp =9.28 and R exp =5.33. The electric resistivity measured by means of the four probe method at room temperature on sintered pellets is about 105 Ω cm. The magnetic susceptibility measurements achieved between 300 and 800 K show the existence of an effective moment μeff =2.27 μB. To cite this article: M. Sellami et al., C.R. Chimie 8 (2005) .

Abstract: Glucantime® is the most common stibied derivative used to treat cutaneous leishmaniasis (CL) in Tunisia; however adverse effects have been reported. Objectives. – This retrospective study deals with the various adverse of intramuscular glucantime® used for CL. Results. – Nineteen patients (21%) receiving intramuscular Glucantime® developed adverse effects. 8 male and 11 female patients, mean age 45, ranging from 8 to 84 years were affected. adverse effects were: fever (3), arthralgia and myalgia (4), nausea and vomiting (2), erythema nodosum (1), acute renal failure (3 including 1 lethal case), hepatic cytolysis (1), skin rash (4), and inflammation of the injection site (1). Conclusion. – Adverse effects of intramuscular Glucantime® were relatively frequent in our series. Arthralgia, myalgia, and skin rash were not severe and disappeared when the treatment was stopped. Stibiointoxication cases, mainly acute renal failure, were serious. [Copyright &y& Elsevier]

Each separate religious tradition combines in its own way elements which favour discrimination, and other elements which favour the equality of the sexes. Within a single religion, different currents of thought have taken different paths, and within each religion there are varying interpretations of the same texts. The status which a given religion assigns to women (and to men) depends upon the position which that religion occupies within a given society. In brief, always two poles, always two terms, always a duality, in the image of this sex, divided by definition in two, but constantly seeking unity. This oscillation promotes the notion of an antinomy to the rank of a concept, making of it the most adequate prism possible. Such a prism is in our sense the most apt for taking account of the internal tension which each religious tradition experiences with regard to the male-female duality. Consequently, this text aims at identifying the principal antinomies which allow us to express the position of Islam with regard to the male-female duality. At the present stage of the development of our thought, we propose distinguishing five antinomies: an antinomy of history, a textual antinomy, a hermeneutic antinomy, a political antinomy, and a contextual antinomy.
