Changing mortality patterns in Nauruans: an example of epidemiological transition.

An analysis of mortality data for the years 1982-5 was carried out for the Micronesian population (aged 15 years and over) of the central Pacific Island, Nauru. Among males, the most common causes of death were circulatory system disorders (33.3%), accidents (25.2%), and diabetes mellitus (12.1%).

The polarization of skylight: An example from nature

A simple analytical model is presented for calculating the major features of the polarization of skylight over a hemisphere centered on an earthbound observer. The model brings together material from different topics in optics: polarization of plane waves, natural unpolarized light, and dipole scattering. Results calculated with the simple model are compared with experimental data. A brief desc...
