Fluoride takes part in a number of geochemical and biochemical reactions. The activity of the fluoride thus makes the ion non conservative in many occations, though the ion is included in the major ions category. Preferential enrichment of fluoride is a general observations in the coastal and estuarine environment.

What are the consequences of rapid global change for the behaviour and ecology of wild species? Answering this very broad question is a challenging but important task. One relatively manageable question under this broad umbrella is how the timing of biological events (i.e., phenology) is changing as the earth's climate changes. In this article, we describe a new programme aimed at assessing the timing of migration of birds that winter in the Indian Subcontinent and monitoring changes

This paper looks at the major problems faced by the wind industry in India. It then tries to address some of the reasons why the attitude of many people is either hostile or indifferent to this technology.
