15 صفحه اولRiver response to climate variability and land-use in the Bernese Alps during the last 2400 years
Gently sloping surfaces for settlement are scarce in high mountains ranges and they are commonly related to distal parts of alluvial fans where floods hazards can be expected. To understanding the influence of external factors, such as climatic variability and land uses, on the alluvial fan accretion and flooding processes, sedimentology and pollen analysis from local site provide valuable data...

Hawking radiation is often intuitively visualized as particles that have tunneled across the horizon. Yet, at first sight, it is not apparent where the barrier is. Here I show that the barrier depends on the tunneling particle itself. The key is to implement energy conservation, so that the black hole contracts during the process of radiation. A direct consequence is that the radiation spectrum...
