Dispersive Estimates for Full Dispersion KP Equations [PDF]
Journal of Mathematical Fluid Mechanics, 2021 AbstractWe prove several dispersive estimates for the linear part of the Full Dispersion Kadomtsev–Petviashvili introduced by David Lannes to overcome some shortcomings of the classical Kadomtsev–Petviashvili equations. The proof of these estimates combines the stationary phase method with sharp asymptotics on asymmetric Bessel functions, which may be ...

Emulsion stability and antimicrobial activity of Ionic liquid-based formulation [PDF]
E3S Web of Conferences, 2021 Chemical dispersants is one of the globally accepted remediation technique used for marine oil spill. However, the toxicity related with these dispersants confined its application in marine environment. Therefore, to overcome this problem, the employment

Dispersive stabilization [PDF]
Bulletin of the London Mathematical Society, 2010 Ill posed linear and nonlinear initial value problems may be stabilized, that it converted to to well posed initial value problems, by the addition of purely nonscalar linear dispersive terms. This is a stability analog of the Turing instability. This idea applies to systems of quasilinear Schr dinger equations from nonlinear optics.

Mathematical model for calculating the force field of loads in the magnetic liquefied layer of electromechanical dispersants [PDF]
E3S Web of Conferences, 2021 The article presents an analysis of the dominant dispersants in the production of the agro-industrial complex. A qualitative transition to the level of a priori reduction of energy costs for the most energy-intensive in the process flow and process ...

Biological Reviews, 2017 ABSTRACTDispersal is a process of central importance for the ecological and evolutionary dynamics of populations and communities, because of its diverse consequences for gene flow and demography. It is subject to evolutionary change, which begs the question, what is the genetic basis of this potentially complex trait?

Influence of Succinimide Dispersants on Film Formation, Friction and Antiwear Properties of Zinc Dialkyl Dithiophosphate [PDF]
, 2012 ZDDP (zinc dialkyldithiophosphate) is arguably the most successful antiwear additive ever employed in crankcase engine lubricants. It was originally used as an antioxidant and shortly afterwards recognized for its antiwear and extreme pressure ...

Evaluation of the dispersants effectiveness using the Baffled Flask Test
Journal of Environmental Engineering and Landscape Management, 2022 The use of chemical dispersants is one of the most widely used methods for responding to oil spills. The most important characteristic of dispersants is their effectiveness.
