Termite soil preferences and particle selections: strategies related to ecological requirements
Insectes Sociaux, 2002At the Lamto Savanna Ecological Station (Cote d'Ivoire), Odontotermes nr. pauperans (Termitidae, Macrotermitinae) was observed to build mounds enriched with fine particles. Using laboratory experiments we studied the selection of building materials by worker termites offered soil from two contrasting horizons: superficial soil (15-20 cm) and a deeper ...

The importance of fine particle technology in the world's ecology
Powder Technology, 1973Abstract 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.

Ecological composite material with oil shale ash particles. Mechanical properties
Engineering for Rural DevelopmentThe need for “ecological” and “green” materials is increasing because of the strong demand to reduce the speed of climate change and decrease carbon footprint of human activities in nature. In the cement production process high amount of CO2 is obtained as by-product.

olymethylsilsesquioxane Oligomers as Ecologically Friendly Binding Agents for Particle Boards
INEOS OPENThe possibility of using multifunctional methylsilsesquioxane oligomers as ecologically friendly binding agents for wood chipboards is investigated. The physical and mechanical properties of the resulting particle boards are studied and compared with those of the boards containing a formaldehyde resin as a binder.

Empirical study of particle swarm optimization inspired by Lotka–Volterra model in Ecology
Soft Computing, 2018Particle 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.

Individual particle measurements to monitor ecological processes in the Indian River Lagoon, FL
Ocean Sensing and Monitoring X, 2018Suspended particles are important components of coastal marine ecosystems that are often the target of environmental sensing efforts (e.g. harmful algae blooms, suspended sediments). Automated measurements of individual particles provide advantages over traditional manual methods of particle analysis and sensors that measure bulk water properties ...

Design of ecological concrete by particle packing optimization
2011The goal of this research project on Ecological Concrete was to reduce the CO2-emission of concrete and to reuse secondary materials form concrete production and other industries simultaneously. This also minimizes the use of natural resources and the production costs.
