Introduction: The abdominal pregnancy is a rare pathology that can threaten the vital prognosis of the mother. The positive diagnosis is difficult to establish. It is most often made in an acute context, leading to a high fetomaternal morbidity and mortality. Our objective is to recall the diagnostic approach and optimal management of this condition. Case report: We present the case of an abdominal pregnancy at 18 weeks of amenorrhea with partial placental abruption in a 26-year-old patient who presented with abdominal pain in emergency obstetrical department of university hospital center of Agadir. The ultrasound revealed the presence of an evolving abdominal pregnancy. The MRI allowed precisely the localization of the placenta and its relationship with the surrounding organs. A laparotomy revealed the insertion of the placenta on the right adnexa. The right adnexectomy allowed removal of the placenta without incident. Conclusion: Abdominal pregnancy is difficult to diagnose. It is essential to be well informed about the clinical and ultrasonographic semiology of this pregnancy, in order to avoid operative surprises and to ensure the appropriate treatment.

This paper is devoted to prove the existence of an exponential attractor for the semiflow generated by a nonlinear Boussinesq equation. We formulate the Boussinesq equation as an abstract equation in the Hilbert space H0^2（0, 1） × L^2（0, 1）. The main step in this research is to show that there exists an absorbing set for the solution semiflow in the Hilbert space H0^3（0, 1） × H0^1（0, 1）.

With the hope of overcoming the generation of hazardous materials to human health and environment, serious and great endeavor have been made in catalyst fabrication using green chemistry technology. In this paper, the manganese （III） acetylacetonate nanoparticles with diameters of about 146 nm were prepared by a simple and environmentally benign route based on hydrolysis of KMnO4 followed by reaction with acetylacetone in rapid stirring rate or ultrasonication. The as-prepared samples were characterized by X-ray diffraction, energy dispersive X-ray fluorescence （EDIX）, Fourier transfer infrared spectroscopy and scanning electron microscope. Various parameters were investigated, and the pure and stable crystals of manganese （III） acetylacetonate could be obtained in 98% conversion at a molar ratio 7：1 of acetylacetone to KMnO4 and 75℃after 60 min. We further proposed a mathematical model, and the predicted results from model were in good agreement with experimental results.
