Compound specific stable isotopes, BIT, pollen and spores of Miocene to Pliocene sediments of ODP Hole 175-1085A

Pollen and stable carbon (d13C) and hydrogen (dD) isotope ratios of terrestrial plant wax from the South Atlantic sediment core, ODP Site 1085, is used to reconstruct Miocene to Pliocene changes of vegetation and rainfall regime of western southern Africa. Our results reveal changes in the relative amount of precipitation and indicate a shift of the main moisture source from the Atlantic to the Indian Ocean during the onset of a major aridification 8 Ma ago. We emphasise the importance of declining precipitation during the expansion of C4 and CAM (mainly succulent) vegetation in South Africa. We suggest that the C4 plant expansion resulted from an increased equator-pole temperature gradient caused by the initiation of strong Atlantic Meridional Overturning Circulation following the shoaling of the Central American Seaway during the Late Miocene.

Herramienta software para el aprendizaje de la generación de la cardiode en un entorno AutoCAD

This article presents a novel application which has been developed in Visual LISP for an AutoCAD environment, and which shows intuitively and quickly the generation of the Cardioid curve in five different ways (conchoid of a circumference, pedal curve of a circumference, inverse of a parabola, orthoptic curve of a circumference and epicycloid of a circumference). This cyclic curve has a large number of artistic and technical applications, among them the profile of some cams.

Situazione attuale delle comunicazioni ottiche

In una panoramica non completa, viene presentata la situazione attuale di alcuni tra i temi piú significativi per quanto riguarda le comunicazioni ottiche. L 'analisi è centrata essenzialmente sulle fibre mono e multimodali, su quelle a caratteristiche speciali, usate nelle comunicazioni coerenti, sui componenti attivi e sulle reti locali.
