    Sammanfattning : The climatic patterns of the world are changing and with them the spatial distribution of global terrestrial carbon; the food and fiber of the world and in itself an important factor in the changing climate. Knowledge of how the terrestrial carbon stock is changing, its distribution and quantity, is important in understanding how the patterns of the world are changing and large scale models using remotely sensed data have emerged for this purpose.

    Sammanfattning : Many studies show that socioeconomic and demographic variables have a strong link with human health which in turn affects life expectancy and age. This paper presents the results of a principal component regression analysis, in order to describe a good regression model for mean age of the population of all the countries in the world. LÄS MER
