Deriving reaction?diffusion models in ecology from interacting particle systems
Journal of Mathematical Biology, 2004 We use a scaling procedure based on averaging Poisson distributed random variables to derive population level models from local models of interactions between individuals. The procedure is suggested by using the idea of hydrodynamic limits to derive reaction-diffusion models for population interactions from interacting particle systems.

Exploitation of Particle Migration Mechanism to Promote Economy and Ecology in Concrete Technology
Key Engineering Materials, 2006 The computer simulation study of Portland cement blending confirmed the major mechanism to be size segregation in the Interfacial Transition Zones around the aggregate particles. Fine particles tend to move through the skeleton of larger particles towards the surface of the aggregate grains, improving local density.

Particle Size Spectra in Ecology
, 1984 The use of size distributions as descriptors of ecosystems goes back at least to Elton (1927), although quantitative applications have appeared only during the past decade. Elton noted that there was a characteristic difference between terrestrial and aquatic ecosystems; on land the organisms in the lower trophic levels tend to be larger than the ...

The importance of fine particle technology in the world's ecology
Powder Technology, 1973 Abstract Fine particle technology has much to offer in controlling the world's ecology. Better and cheap instrumentation for sampling of particulates needs to be developed. The collection efficiencies of existing particle removal systems must be improved and novel methods to remove more than one pollutant in a system must be invented.

Journal of Theoretical Biology, 2014 The particle capture efficiency, η, of systems that remove suspended particles from ambient flow (e.g. suspension feeding, abiotic pollination) has been studied using static collectors in steady flows. Particle deposition on collectors moving due to fluid flow remains largely unknown, despite its ecological relevance.

Empirical study of particle swarm optimization inspired by Lotka–Volterra model in Ecology
Soft Computing, 2018 Particle swarm optimization (PSO) has been proved to be an effective technique in solving complex global optimization problems. Many modified versions of the original PSO algorithm emerged during the last 15 years. Many of those existing methods employ all particles in a single population which adopts the similar monotonic strategy.

Science, 2016 Microplastic's triple threat The billions of tons of plastics that we release into the environment for the most part do not biodegrade. But they do degrade, breaking into ever smaller particles that end up in the oceans. Lönnstedt et al.

Automobile exhaust has become the main source of atmospheric particulate matter with the increase in the number of automobiles. Automobile exhaust particles (AEPs) discharged into the atmosphere can enter the aquatic environment through atmospheric deposition, rain runoff, leaching, drainage water and urban sewage and further affect aquatic organisms ...
