Succinonitrile dendrites, growing under steady-state conditions, are subjected to a rapid change in pressure. This leads to a rapid change in thermal driving force from the corresponding change in equilibrium melting temperature due to the Clapeyron effect, and a change in the far-field temperature due to adiabatic temperature changes in the bulk liquid and solid. This allows us to observe a de...

Observational data (i.e., data that records observations and measurements) plays a key role in many scientific disciplines. Observational data, however, are typically structured and described in ad hoc ways, making its discovery and integration diÆcult. The wide range of data collected, the variety of ways the data are used, and the needs of existing analysis applications make it impractical to...

Hydrocarbon exploration has been underway in the north of West Siberia for several decades. Giant gas fields on the Yamal Peninsula are expected to begin feeding the Nord Stream pipeline to Western Europe in late 2012. Employing a variety of highto very high-resolution satellite-based sensors, we have followed the establishment and spread of Bovanenkovo, the biggest and first field to be develo...

Vermiculations are aggregates of small particles commonly found on cave walls. They a major concern for the conservation painted caves, as they can potentially alter valuable prehistoric paintings. A previous rheological study fine sediment deposits walls revealed that this material undergo solid-to-liquid transition triggered by variations in chemical composition water film wall. Such could oc...
