متن کاملMan made deltas
The review of geochronological and historical data documents that the largest southern European deltas formed almost synchronously during two short intervals of enhanced anthropic pressure on landscapes, respectively during the Roman Empire and the Little Ice Age. These growth phases, that occurred under contrasting climatic regimes, were both followed by generalized delta retreat, driven by tw...

practice, the detection Ii mit of scanning electron microscopy is about 0.1 j.m (Middleton, 1982). Transmission electron microscopy may be required to detect very thin fibres (Rood & Streeter, 1985). The elemental composition of individual fibres can be determined with an energy-dispersive X-ray ana1ysis attachment combined with an electron microscope (Middleton, 1982). Fibres are counted and s...
متن کاملTweet Factors Influencing Trust and Usefulness During Both Man-Made and Natural Disasters
To this date, research on crisis informatics has focused on the detection of trust in Twitter data through the use of message structure, sentiment, propagation and author. Little research has examined the usefulness of these messages in the crisis response domain. Toward detecting useful messages in case of crisis, in this paper, we characterize tweets, which are perceived useful or trustworthy...
