Using dispersants after oil spills: impacts on the composition and activity of microbial communities

open access: yesNature Reviews Microbiology, 2015
Dispersants are globally and routinely applied as an emergency response to oil spills in marine ecosystems with the goal of chemically enhancing the dissolution of oil into water, which is assumed to stimulate microbially mediated oil biodegradation ...

Competition for Dispersal in Ant-Dispersed Plants

Science, 1981
Two closely related and coexisting plants (Chenopodiaceae) of the Australian arid zone are adapted for seed dispersal by ants. These facultatively perennial shrubs persist in saltbush communities largely as a result of highly directional dispersal to ant mounds, where conditions are favorable for establishment and growth.

Level of dispersion in dispersed particle filter

2015 20th International Conference on Methods and Models in Automation and Robotics (MMAR), 2015
In the paper an impact of the calculations dispersion level in a power system on the estimation quality has been presented. The dispersion level has been changed from the smallest (calculations for the whole system) to the largest (individual calculations in each node of the system).

Dispersal dilemmas

Nature Ecology & Evolution, 2018
A coordinated distributed experiment, replicated across multiple labs and multiple taxa, reveals that both resources and predators govern dispersal between habitats, affecting local and regional stability of biological communities.

Decentralisation, Dispersal and Dispersion

South African Geographical Journal, 1974
Abstract The terms decentralisation, dispersal and dispersion are used extensively in the literature of regional economic development. The first may refer to the decentralisation of core areas, to the process of dispersal, or to the state of a spatial system. The second term is concerned mainly with process and the third with pattern but no consistency

Dispersion and dispersing agents

Pigment & Resin Technology, 1973
The term dispersion is used to refer to the process of incorporating a powder into a liquid medium so that the final product consists of fine particles distributed throughout the medium. The dispersion is termed ‘colloidal’ if at least one dimension of the particles is <1µ>1mµ.

Dispersion, agglomération et re-dispersion ?

Revue d’Économie Régionale & Urbaine, 2002
Résumé Cet article a pour but de présenter de manière synthétique les principaux résultats théoriques obtenus récemment en économie géographique. Pour cela, on utilise un nouveau modèle qui permet d’établir de manière simple des résultats analytiques. Ce modèle est ensuite utilisé pour étudier un certain nombre de questions peu abordées jusqu’à présent

On the Theory of Dispersion

Physical Review, 1936
I. The measured absorption is the difference between absorption and forced emission. This has to be taken into account in the interpretation of measurements in the infrared and the absorption of hot gases, particularly in the sun. II. According to Maxwell's theory, ${n}^{2}=\ensuremath{\epsilon}\ensuremath{\mu}$.
