Leaf fossils severe end-Cretaceous plant extinction Patagonia
2021/1/18
The asteroid impact 66 million years ago that ushered in a mass extinction and ended the dinosaurs also killed off many of the plants they relied on for food. Fossil leaf assemblages from Patagonia su...
FRACTAL DIMENSIONS FOR RADIOISOTOPE POLLUTION PATTERNS BY NUCLEAR POWER PLANT ACCIDENTS
Chernobyl, deposit fractal Fukushima
2015/5/7
The radioisotope pollution shows two types of patterns: dry and wet deposits for nuclear power plant accidents. Two surface pollution patterns were analysed by fractal. In Fukushima nuclear power pl...
