Introduction: Neonatal asphyxia (NA) is one of the most likely causes of neuro-developmental abnormalities in children. In mali it is responsible for half of the early deaths and the third of neonatal mortality. Updated data would help understand and improve intervention strategies to reduce mortality. Objective: It is the study of epidemiological and clinical characteristics, the immediate outcome and the factors associated with newborn (NB) mortality with NA. material and methods: This was a prospective cross-sectional study from June 27th to September 3rd 2016 about the NBs admitted for NA in the Hospital Teaching Gabriel Touré of Bamako. The clinical and biological data including the prognosis were collected from the health records of women, the liaison sheets and the medical file. The analysis was done using the software epi info version 3.5.1. Results: 76 NBs were included which represented 23.45% of hospitalizations. The majority (89.5%, n = 68) were admitted to less than 24 hours of life for NA grade III according to the Sarnat classification (43.4%, n = 33). The average age of mothers was 24.17 ± 5.5 years. Almost half (41.3%, n = 31) were primigravida. The most common obstetrical event was dystocia (64.5%, n = 49). The prognosis was poor in grade III anoxia in our patients (56%) of deaths. Conclusion: The périnatal anoxia (PA) is a major health issue in mali because of its frequency and severity. monitoring of pregnancies, delivery assisted by skillful and qualified personnel, mastery of neonatal resuscitation techniques are good means of prevention.

Journal of environmental Sciences 2002年第4期14卷 464-473页

作者： m.e.Soltan Chemistry Department Faculty of Science

environmental chemical study were carried out on the Fatimid cemetery marsh at Aswan City(24°1'N and 32°9'e), egypt. marsh contents(warter, soil, sediment, metal and nonmetal bearing salts, and emergent weed) were analysed to known the source of marsh water, speciation of the different elements between the marsh contents, and the toleration of emergent weed (Phargmites australies) for different metals and their bioaccumulation coefficients. Thus, metals(Ca, mg, Na, K, Ni, Fe, mn, Cu, Zn, Cd and Pb) and nonmetals(CO 2- 3, HCO - 3, Cl -, SO 2- 4, PO 3- 4, NO - 3, SiO 2, organic matter and pH value) were determined in the samples. According to the chemical analysis, and applying the base exchange equation(water type) and calculate the hydrochemical parameters for marsh water samples, we can indicate that the marsh water is ground water with Na SO 4 type and deep meteoric genesis. Topsoil of marsh dry land characterized by CaCl as dominant salt,while NaCl is a dominant salt in subsoil. The elevated pH values of marsh contents minimized the metal solubilities in different samples. Phragmites australies showed a strong ability to accumulate mn and Fe in the aerial part in opposite to Co, Ni and Cd.

Some geometrical properties of Ω are determined. The thermodynamic quantities for an ideal gas enclosed in Ω are examined by using the asymptotic expansions of (t) for short-time t. It is shown that the ideal gas can not feel the shape of its container Ω, although it can feel some geometrical properties of it.

The trace of the wave kernel μ（t） =∑ω=1^∞ exp（-iteω^1/2）, where {eω}ω^∞=1 are the eigenvalues of the negative Laplacian -△↓2 = -∑k^3=1 （δ/δxk）^2 in the （x^1, x^2, x^3）-space, is studied for a variety of bounded domains, where -∞ 〈 t 〈 ∞ and i= √-1. The dependence of μ （t） on the connectivity of bounded domains and the Dirichlet, Neumann and Robin boundary conditions are analyzed. Particular attention is given for a multi-connected vibrating membrane Ω in Ra surrounded by simply connected bounded domains Ω j with smooth bounding surfaces S j （j = 1,……, n）, where a finite number of piecewise smooth Dirichlet, Neumann and Robin boundary conditions on the piecewise smooth components Si^＊（i = 1 ＋ kj-1,……, kj） of the bounding surfaces S j are considered, such that S j = Ui-1＋kj-1^kj Si^＊, where k0=0. The basic problem is to extract information on the geometry Ω by using the wave equation approach from a complete knowledge of its eigenvalues. Some geometrical quantities of Ω （e.g. the volume, the surface area, the mean curvuture and the Gaussian curvature） are determined from the asymptotic expansion ofexpansion of μ（t） for small │t│.
