All of us live in two worlds. One is the human world, which includes populations, countries, cities, roads, rail lines, shipping lanes and flight paths. It is the most familiar world and we consciously interact with it every day. It is a world entirely of our construction. It is the world of civilization, of education and of science. The other is the natural world, with mountains, rivers, conti...

For an epidemiologic approach to the etiology of cerebrovascular disease by comparing with that of arteriosclerotic and degenerative heart diseases, the latest regional data for mortality from those diseases were collected from most European countries in 1964. The peculiar gradient of the mortality rate distribution in the respective countries is interpreted by physicochemical factors of natura...

To constrain the timing of rifting in the western, eastern, and northern parts of the Alboran Sea basin, seismic reflectors, corresponding to biostratigraphic boundaries and unconformities from the Miocene to Recent, are correlated using synthetic seismograms. Regions of adjacent coeval compression and extension are found in the Alboran Sea basin. Normal faulting continues in parts of the easte...
