The objective of this research is double: <p>1) to study the factors associated with the problems of quality with drinking water on the physicochemical and biological level in the municipality of Abomey-Calavi in Benin ;<p>2)to study its relationships with public health. <p>The goal is to bring on one hand, the tools of improvement to the quality of water and public health in this commune. In addition, to contribute to the reduction of the rate of morbidity and mortality generated by the diseases related to drinking water contamination in this locality<p><p>Methods:<p>For the purpase of this study, we made a preliminary investigation in the municipality (households 55898 and almost all the households have the traditional wells). In the same way the information provided by the National Society of Water in Benin gave the indications on the level koverage of drinkable water conveyance of the commune. This study carried out within a general logical framework of the durable development based on an DPSIR analysis in the municipality of Abomey-Calavi of the Atlantic district in Benin made it possible to provide information on the main sources of contamination of the drinking water. We also carried out a random sampling of 110 wells and 110 households by taking account into the geographical distribution of the households in the commune. We selected 60 taps and 60 households by random sampling for those using water drink distributed by the national Society of Water in Benin. In each zone or district, three households consuming either well water or tap water were drawn randomly. A retrospective study on the number of cases of the hydrous diseases and other symptoms of hydrous diseases was carried out by consultation of medical registers of the commune from 2007 to 2009. Cases of diarrhoeas used as basic variable of health were compared with the other cases of hydrous diseases available in the files. <p><p>Results:<p>The results show that: the most al the well water taken in the households has temperatures beyond the recommendation of the World Health Organization (25 °C) and 98.2 % have a pH below the normal which is 6.5 to 8.5. We note a strong mercury and cadmium, complete iron, aluminum, nitrate nitrite pollution of the sampled wells (n=110) which is respectively 32.73%, 11.82%,10%, 43.64%, 6.36% and 14.55%. The results of the bacteriological analysis of water revealed that the totality of the wells is contaminated. The germs identified during the analysis of the well water are: Escherichia coli, fecal streptococcus species, bacterial salmonella ,Shigella ,Clostridium perfringens, staphylococcus species,<p> Klebsiella pneumoniae and Pseudomonas aeruginosa Most frequent among these germs are: Escherichia coli (100%), Klebsiella pneumoniae (97.27%), bacterial salmonella and Shigella (96,36%) with regard to the coliformes and enterobacteries. As for the cocci with Gram (+) they are staphylococcus species (97.27%) and the fecal streptococcus (88.18%). It is useful to stress that all the wells are strongly contaminated by Clostridium perfringens (95.45%).<p> The differences between the respective prevalence of parasitic coprology, uroculture, diarrhoeas, pains abdominal and saddles bloody for exposed (45.4%, 71.8%, 76.4% and 59.1%) :those who consume the water of wells not exposed (8.3%, 1.7%,13.3%, 16.7): those who consume tap water, are statistically significant (p<0.001). For diarrhoeas according to the characteristics of the people reached of hydrous diseases and other symptoms of hydrous diseases we have: <p>•\ / Doctorat en Sciences de la santé publique / info:eu-repo/semantics/nonPublished

C’est le droit des entreprises en difficulté qui a permis de mettre en évidence la complexité que pouvait revêtir la détermination de la date de naissance des créances. Or, celle-ci apparaît fondamentale en droit privé. Constituant le critère d’application de certains mécanismes juridiques, elle incarne l’existence de la créance et représente dès lors un enjeu pour toute règle de droit ayant celle-ci pour objet ou pour condition. Deux courants doctrinaux s’opposent, la thèse classique fixe la date de naissance au stade de la formation du contrat, tandis que des thèses modernes la fixent au stade de l’exécution du contrat. La thèse matérialiste, fondée sur le droit des entreprises en difficultés, fait naître la créance de prix au fur et à mesure de l’exécution de la contre-prestation. La thèse périodique, reposant sur une réflexion doctrinale quant aux contrats à exécution successive, fait renaître toutes les créances du contrat à chaque période contractuelle. L’examen des thèses moderne à l’aune des mécanismes juridique qui ne peuvent qu’incarner la véritable date de naissance de l’authentique créance aboutit à leur invalidité. La thèse classique se trouve donc à nouveau consacrée. Mais la résistance que lui oppose le droit des entreprises en difficulté ne peut reposer sur la technique d’une fiction juridique, car d’autres manifestations du même phénomène peuvent être mises en évidence en dehors de ce domaine. Un changement de paradigme s’impose donc pour résoudre le hiatus. Derrière ce phénomène persistant se cache en réalité une autre vision, une autre conception de la créance, la créance économique qui vient s’articuler avec la créance juridique dans le système de droit privé pour le compléter. La dualité des dates de naissance recèle donc en son sein une dualité du concept de créance lui-même, la créance juridique classique et la créance économique. La créance économique n’est pas un droit subjectif personnel. Elle n’est pas la créance juridique. Elle n’est pas autonome de la créance juridique et ne doit pas être confondue avec une créance née d’un cas d’enrichissement sans cause. La créance économique représente la valeur produite par le contrat au fur et à mesure de l’exécution de sa prestation caractéristique. Elle permet de corriger l’application ordinaire du concept de créance juridique par en assurant la fonction de corrélation des produits et des charges d’un bien ou d’une activité. Ses domaines d’application sont divers. Outre son utilisation dans les droits comptable et fiscal, la créance économique permet la détermination de la quotité cédée dans le cadre d’une cession de contrat, la détermination du gage constitué par un patrimoine d’affectation dans le cadre de la communauté légale, de l’EIRL ou encore de la fiducie, ainsi que la détermination du passif exempté de la discipline d’une procédure collective. Dans ces domaines, ce n’est donc pas la date de naissance de la créance juridique qui s’applique, mais la date de naissance de la créance économique. La cohérence du système de droit privé se trouve donc ainsi restaurée quant à la date de naissance de la créance. / It is the laws governing companies experiencing difficulties which have revealed the complexity of determining the dates of the origination of the claims. And yet this appears to be fundamental in private law. As it constitutes the criterion for implementing certain legal mechanisms, it epitomizes the existence of the claim and hence represents a challenge for any rule of law in which the existence of this claim is a goal or condition. There are two conflicting doctrinal currents: the traditional approach sets the date of origination at the stage of the formation of the contract, while modern approaches situate it at the stage of the execution of the contract. The materialistic approach, based on the law governing companies experiencing difficulties, staggers the origination of the price debt over the period of the execution of the service. The periodical approach, which relies on a doctrinal reflection on successive execution contracts, is that of the re-origination of all the claims under the contract at each contractual period. An examination of the modern approaches, under the auspices of the legal mechanisms which can only epitomize the true date of origination of the authentic claim leads to the invalidity thereof. The traditional approach is therefore once again consecrated. But the resistance constituted by the laws governing companies in difficulty cannot rely on the technique of legal fiction, because other manifestations of the same phenomenon can be identified outside this domain. Therefore, a change of paradigm is in order if the hiatus is to be resolved. Behind this persistent phenomenon lies in fact another vision, another concept of the claim: the economic claim which, interwoven with the legal claim in the private law system, supplements it. The duality of the dates of origination therefore conceals in its bosom the duality of the very concept of a claim, the traditional legal claim and the economic claim. The economic claim is not a subjective personal right. It is not a legal claim. It is not autonomous of the legal claim and must not be confused with a claim originating in a case of unwarranted enrichment. The economic claim represents the value produced by the contract as the service which characterizes it is provided. It permits the rectification of the ordinary application of the concept of legal claim by ensuring the function of correlating the proceeds with the costs of a commodity or an activity. Its domains of application are varied. In addition to its use in accounting and fiscal law, the economic claim permits the determination of the portion transferred in the context of the transfer of a contract, the determination of the collateral consisting in a special-purpose fund in the context of a legal joint estate, a limited liability individual contractor or a trust, as well as the determination of the liabilities which escape the discipline of collective proceedings. In these domains, it is therefore not the date of origination of the legal claim which applies, but the date of origination of the economic claim. The coherence of the private law system is therefore restored as concerns the date of the origination of the claim.
