The mechanism of polymerization is linking to the structural viscosity η*(t, x) which depends on the time t and a controlling parameter x. The controlling factor which influences the aggregation dynamics can be limited to, say, the volume functi [...]

We present the Jacobi’s second equality in the form of stochastic equation. By the theorem of factorization of the solution of Fokker- Planck equation, the solution of Bloch equation is obtained and using the Matsubara formalism we determine the w [...]

To this purpose, one uses the result that quantum phenomena in the Euclidean formulation of the theory are due to a stochastic space-time background interaction, whose essence is the time derivative of the Wiener process. The problem of calculating [...]

The objective of this article is the generalization of the homogeneous reaction-diffusion equations of the monostable or bistable types. From the non-linear second order differential equation of the front profile (solution of the homogeneous react [...]

Groundwater plays a major role in supplying domestic water to millions of people in Africa. In the future, the ability to increase reliable water supplies for domestic and possibly irrigation purposes will depend on groundwater development. Groundwat [...]

In majority of the countries in the process of development like the Benin, the presence of dumpsite of rubbish can cause pollution of the groundwater. Indeed, the leachate resulting from the seepage of rain water into rubbish can infiltrate and pol [...]
Hundreds of thousands of boreholes have been drilled in hard rocks of Africa and Asia for supplying human communities with drinking water. Despite the common use of geophysics for improving the siting of boreholes, a significant number of drilled h [...]
Given the gradual improvement of living conditions and aging, dementia and related syndromes are becoming serious problems in the developing countries. A cross-sectional door to door type study in neighbourhood, was conducted from October 2008 to Jan [...]

En Afrique de l'Ouest, les échanges d'énergie entre la surface et l'atmosphère jouent un rôle crucial dans la boucle de rétroaction entre humidité du sol et précipitations. Toutefois, ces échanges sont encore mal documentés dans cette région. L'objec [...]

Latent and sensible heat surface fluxes are key factors of the western African monsoon dynamics. However, few long-term observations of these land surface fluxes are available; these are needed to increase understanding of the underlying processes an [...]
