INTRODUCTION Research during the last 20 years, has led to a major expansion in knowledge about long-term climatic variability and dynamics. Two developments, in particular, have advanced the theoretical understanding of the major environmental changes that induce continuous changes in ecosystems and in the distributions of plant and animal taxa. The first development was a recognition that the...

Predictable and unpredictable variations are two major causes of renewable energy-related intermittency. Such a drawback could be overcome by applying new energy management strategies, particularly storage systems. This paper investigates the feasibility introducing photovoltaic string, enabling maintenance continuous supply capacity. Accordingly, PV system is liable to perform at maximum effic...

Malaria remains endemic in tropical areas, especially in Africa. For the evaluation of new tools and to further our understanding of host-parasite interactions, knowing the environmental risk of transmission--even at a very local scale--is essential. The aim of this study was to assess how malaria transmission is influenced and can be predicted by local climatic and environmental factors.As the...
