« … Quatre sales enfants métisses ... » - Colonisation par adaptation ? Le cas de Yaoundé.

The article wants to describe, how far colonial administration accepted to adopt local policies of colonized societies. The case study is about the early years of the Jaunde station in German Kamerun. / Le présent article pose la question de savoir jusqu’à quel niveau le pouvoir colonial allemand a été prêt à s'adapter à la situation sociale qu'il a trouvé sur place. La question est traitée à l'exemple de l'histoire du poste de Jaunde (Yaoundé) au Kamerun allemand. // Cameroun (1884-1916), Yaoundé, Georg August Zenker (1855-1922), Richard Kund (1852–1904), Hans Tappenbeck (1861-1889), Kurt von Morgen (1858-1928), Hans Dominik (1870-1910), Essono Ela, Omgba Bisogo, Jaunde, Kamerun, Colonisation allemande

INTEGRATION D’UN OBSERVATOIRE URBAIN SUR GOOGLE MAPS : Cas des infrastructures de la santé de la ville de Douala Cameroun

The spectacular advances computer science applied to geographic information systems (GIS) in recent times has favored the emergence of several technological solutions. These developments have given rise to enormous opportunities for digital management of the territory. Among the technological solutions, the most famous Google Maps offers free online mapping dynamic exhaustive of the Maps. In addition to meet the enormous needs of urban indicators geotagged information, we did work on this project “Integration of an urban observatory on Google Maps.” The problem of geolocation in the urban observatory is particularly relevant in the sense that there is currently no data (descriptive and geographical) reliable on the urban sector; we must stick to extrapolate from data old and obsolete. This helps to curb the effectiveness of urban management to make difficult investment programming and to prevent the acquisition of knowledge to make cities engines of growth. The use of a geolocation tool coupled to the data would allow better monitoring of indicators Our project's objective is to develop an interactive map server (WebMapping) which map layer is formed from the resources of the Google Maps servers and match information from the field to produce maps of urban equipment and infrastructure of a city data to the client's request To achieve this goal, we will participate in a study of a GPS location of strategic sites in our core sector (health facilities), on the other hand, using information from the field, we will build a postgresql database that will link the information from the field to map from Google Maps via KML scripts and PHP appropriate. We will limit ourselves in our work to the city of Douala Cameroon with the sectors of health facilities with the possibility of extension to other areas and other cities.

Contribution à l’étude de l’influence des caractères physico-chimiques du sol sur la stabilité structurale ; cas de la plaine de Sidi Bel Abbes

The aim of the study is to contribute to the knowledge and the identification of the main physical and chemical characteristics of the soil that affect the structural stability of soil types forming the soil cover of the plain of Sidi Bel Abbes region for agricultural use by excellence. Structural stability is an indicator of the cohesion of soil aggregates. This is a parameter that expresses the ability of soil aggregates to resist degradation in general the impact of rain or excess water. Measuring the structural stability makes it possible to evaluate the sensitivity a soil crusting and erosion. The results showed that soils subject of our study are stable and very stable with a slight difference. We have a statistical study made it possible to establish a correlation between the structural stability and other physical and chemical soil parameters measured )fersiallitic red soil and brown calcareous soil( such as organic matter content, the rate of total limestone and soil texture, to better explain the stability or instability of the soil structure and to establish a relationship between these parameters and the structural stability. // Keywords: Sidi Bel Abbes, chemical characteristics, physical, structural stability, soil, plain, fersiallitic red soil, brown calcareous soil

Les conflits armés au regard de la Cour Pénale Internationale. Cas de la Cote d'Ivoire De 2010 à 2012

In this work, will be discussed to analyze the armed conflict in Cote d'Ivoire has experienced over the years 2010-2012 under the intervention of the International Criminal Court. We have to give more details on these issues and meet certain circumstances that glazed the conflict.
