Use of (137)Cs technique for soil erosion study in the agricultural region of Casablanca in Morocco.

Accelerated erosion and soil degradation currently cause serious problems to the Oued El Maleh basin (Morocco). Furthermore, there is still only limited information on rates of soil loss for optimising strategies for soil conservation. In the present study we have used the (137)Cs technique to assess the soil erosion rates on an agricultural land in Oued el Maleh basin near Casablanca (Morocco). A small representative agricultural field was selected to investigate the soil degradation required by soil managers in this region. The transect approach was applied for sampling to identify the spatial redistribution of (137)Cs. The spatial variability of (137)Cs inventory has provided evidence of the importance of tillage process and the human effects on the redistribution of (137)Cs. The mean (137)Cs inventory was found about 842 Bq m(-2), this value corresponds to an erosion rate of 82 tha(-1) yr(-1) by applying simplified mass balance model in a preliminary estimation. When data on site characteristics were available, the refined mass balance model was applied to highlight the contribution of tillage effect in soil redistribution. The erosion rate was estimated about 50 tha(-1) yr(-1). The aspects related to the sampling procedures and the models for calculation of erosion rates are discussed.

[Transfusion practice and attitudes].

During last years, blood transfusion and transfusion security were domains which have preoccupied health authorities, the population and health professionals. Beginning with the principle that blood transfusion is a care that must be under medical responsibilities, authors analyse physician's implication in this field. To reach this objective, a study interested 199 young physicians, working in two university hospitals in Tunisia. Results indicate that physician's knowledge about blood transfusion is insufficient to guarantee quality of this medical act. In terms of attitudes and practices, physicians are not really always implicated in the different stages of blood transfusion process. Intervention is limited to prescription and blood transfusion record card writing. Transfusion herself and monitoring were, in particular, delegated to nurses. So transfusion incidents were under--declared. Transfusion medicine must occupy important place in physicians curriculum. At hospital level, quality insurance process, based on audit, have to be implemented to obtain transfusion good practices, in a domain were risks are unfortunately not yet totally circumscribed.

[Costs of basic health services in a health district in Tunisia].

Information on the cost of health services is essential for good planning and management and the efficient use of resources. We calculated the total costs incurred in running primary health services for one year (1995) in the health district of Enfidha (Tunisia). The yearly operating expenditure for the health district was 1 219 099 Tunisian dinars and the cost per inhabitant was 17.494 dinars (US dollar 1 = Tunisian dinar 0.950 in 1995); 65.37% of total costs went on staff and 17.03% on drugs. Looked at another way, 84,96% went on curative services and 14.04% on preventive services. The cost of a consultation for curative care was 6.847dinars, for perinatal care was 2.764 dinars, for immunization was 3.680 and for school visit was 6.680 dinars. The study helps to identify ways in which cost analysis can be used to explore efficiency and resource adequacy in the district.
