The detection and the estimate of the air pollution by total hydrocarbons by using a biological sensor was used for the first time in the area of Skikda located at the Algerian North-East. Capital of petrochemistry, the urban zone of Skikda is to confront with a rather strong hydrocarbon air pollution generated by a diffuse source which includes several hearths of emanations: motor vehicle traffic, domestic hearths and the petrochemical complex. The choice of the bio-indication by the use of...

Many of the public schools and universities lack the facilities to adequately support education in the physical and biological sciences. The literacy rate needs to be improved to promote better understanding of health matters. In the summer of 2004 three...

Schools and the production of gendered identities: insights from Ghana and BotswanaDunne, M. - 2007
This paper presents findings from a study of schools in Botswana and Ghana that focused on how processes of school life influence gender identities (Dunne et al, 2005). The theoretical analysis of formal and informal institutional rules and practices highlights how gender / sexual identities are formed and enacted in schools. While a dominant gender issue in education and development discourses concerns the access, retention and performance of girls, this analysis also has relevance to boys....

The late twentieth century witnessed a series of profound transformations in higher education. These have included the reorganisation of the governance and management of institutions, the increasing globalisation of education provision, the impact of new technology on delivery and content, and the increasing marketisation of higher education in a context of tighter resources for public expenditure (Neave, 2000).

In sub-Saharan Africa approximately 125,000 extension workers hold either certificates or diplomas. Only about 25,000 hold degrees from universities. Many start their careers in extension with a weak understanding of agricultural science and the strategies to transfer education to farmers. This study assessed the Sasakawa Africa Fund for Extension Education (SAFE) program regarding the perceived job competence of mid-career extension staff that completed the SAFE initiated BS agricultural...
