Planet formation is accompanied by the formation of comet clouds. In systems where planets migrate on rapid timescales, the diffusive evolution of comet orbits may stall, resulting in a comet cloud intermediate between a flattened Kuiper Belt and a spherical Oort cloud. These ‘failed Oort clouds’ may provide a ‘smoking gun’, indicating that planetary migration has taken place. If some fraction ...

investigations in recent decades have shown an unexpected increase in aerosol concentrations in metropolitan and industrialized regions. it was sometimes followed by heat islands and probably decreases in precipitation due to an inadvertent cloud overseeding process. particle pollutants act like small cloud condensation nuclei in which they form large collections of small droplets in cloud. col...

FINESCE is the Smart Energy use case project of the Future Internet Public Private Partnership Programme. It aims at defining an open infrastructure based on Information and Communications Technology (ICT) used to develop new solutions and applications in all fields of Future Internet related to the energy sector. To accomplish this goal a cloud-based environment is proposed, providing high sca...

Cloud computing has been marketed as having multiple benefits. However, organizations remain hesitant to adopt it. For cloud computing providers, it is important to understand how to influence organizations’ adoption decision. However, extant literature has focused on cloud computing’s architecture, potential applications, and costs and benefits without understanding how organizations’ percepti...

We present an analysis of wide-field infrared extinction maps of a region in Perseus just north of the Taurus-Auriga dark cloud complex. From this analysis we have identified a massive, nearby, but previously unrecognized, giant molecular cloud (GMC). Both a uniform foreground star density and measurements of the cloud’s velocity field from CO observations indicate that this cloud is likely a c...

cumulus parameterization in numerical weather prediction models can significantly affect severe weather forecasts, such as hurricanes, flash floods, and winter storms. the role of convection is essential in stabilizing an unstable atmosphere through vertically transferring moisture, energy, chemical species and momentum. cumulus parameterization schemes use simple one-dimensional convective clo...

in this article cloud-point extraction (cpe) was used with chelating agent to extract uranium from aqueous solutions. the methodology used is based on the formation of metal complexes soluble in a micellar phase of surfactant. the metal ions complexes are then extracted into the surfactant-rich phase at a temperature above the cloud-point temperature. the effect of type of surfactants and ligan...

Observational constraints on the theory of the IMF are reviewed. These observations include the new result that star formation is very rapid, usually going from start to finish in only 1 or 2 dynamical times on a wide range of scales. This result, combined with the observation that the IMF is independent of cluster density over a factor of several hundred, implies that protostar coagulation dur...
