Pupils attending 12 schools for the blind in Malawi, 3 schools in Kenya and 2 schools in Uganda were examined to determine the causes of severe visual impairment or blindness (visual acuity in the better eye of less than 6/60). A total of 491 pupils aged 3-22 years was examined. Visual acuity was measured in each eye using a Snellen E chart. The anatomical site of abnormality and underlying cause of visual loss were determined by clinical examination for each eye, and for the child....

A multidisciplinary project was conducted to study the impact of an important phosphogypsum discharge (50 million tons discharged near Gabes city over twenty years). Analysis of remote sensing data (Landsat MSS, SPOTXS and P, NOAA AVHRR) combined with field measurements were used to describe actual and historical states and begin understanding alteration mechanisms. The satellite information concerns bottom changes, sea color, sea surface temperature, and swell. Drastic changes have occurred...
