[1] We show that simple thermodynamic models of convective plumes predict the area fraction of convective plumes (i.e., updrafts) in Titan’s atmosphere to be 12 smaller than on Earth. This result is in agreement with predictions by sophisticated dynamical models and with the relative tropospheric cloud cover, which is only 1% on Titan. Rainstorms on Titan, being so rare, may be violent. Citatio...

Abstract The electrostatic properties of clay (or other charged) mineral surfaces play a significant role in the fate, transport, persistence, and remediation subsurface contaminant plumes. This study presents stochastic assessment impact relevance microscale effects on macroscopic, field-scale transport heterogeneous groundwater systems involving spatially distributed zones. We present Monte C...

In cold climates, the use of de-icing chemicals in winter can lead to groundwater contamination, especially when used large quantities, such as at airports. Oslo Airport, Gardermoen, is situated on Norway’s largest rain-fed aquifer. Potassium formate remove ice from runways and propylene glycol airplanes; organic parts are degradable. Most wells monitor spread underlying aquifer have well scree...

ultrasonic technology as an innovative technology may be used for water and wastewater treatment for pollution removal. this technology acts as an advanced oxidation process. application of this technology leads to the decomposition of many com­plex organic compounds to much simpler compounds during physical and chemical compounds during cavitation proc­ess. in this article review, some applica...

A vertical soap film is maintained by injection of a soap solution from the top. The film is then locally heated. Thermal plumes may be observed to rise in the film, depending on the magnitude of the heating and injected flows. The nearly two-dimensional nature of the system allows to visualize the motion of the plumes using an infrared camera. A model is proposed to describe the growth, emerge...

Knowledge of the distribution of groundwater contaminant plumes is needed to avoid pumping contaminated water, assess past exposure to contamination, and design remediation schemes to contain or treat the contaminated area. In most field cases, however, contamination is discovered by a small number of fortuitously located wells, and the full distribution of the plume is never known. This paper ...

We present GraphScan, a novel method for detecting arbitrarily shaped connected clusters in graph or network data. Given a graph structure, data observed at each node, and a score function defining the anomalousness of a set of nodes, GraphScan can efficiently and exactly identify the most anomalous (highest-scoring) connected subgraph. Kulldorff's spatial scan, which searches over circles cons...

L'observation du comportement du goeland brun au nid (Larus fuscus) a perm is d'observer 1'effet it long terme de nombreux lacteurs sur le lissage des plumes, le sommeil et d'autres activites non determinees. Le nombre des animaux observes augmentait en raison directe de l' avancement de la saison et en raison inverse des minima thermiques quotidiens. Les maxima thermiques quotidiens sont en co...
