Implications of network particle tracking (NPT) for ecological model interpretation
Ecological Modelling, 2009Abstract Network particle tracking (NPT), building on the foundation of network environ analysis (NEA), is a new development in the definition of coherence relations within and between connected systems. This paper evaluates three ecosystem models in a comparison of throughflow- and storage-based NEA and NPT. Compartments in models with high indirect

Multi-Reservoir Ecological Operation Using Multi-Objective Particle Swarm Optimization
Applied Mechanics and Materials, 2014Traditional reservoir operation ignores ecological demands of rivers. This would probably lead to degradation of river ecosystem. In order to alleviate the influence of reservoirs on river ecosystem, multi-objective reservoir ecological operation was proposed from perspective of maintaining the river ecosystem health. Multi-objective mathematical model

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 ...

Purification Effect on Particle Size of Matrix in Ecological Filter Bed
Applied Mechanics and Materials, 2012In order to study the purification effect on the particle size of matrix in ecological filter bed, four ecological filter bed units with different particle sizes (0~2mm, 2~15mm, 15~30mm, 30~50mm) are designed to purify the polluted river water. Results show that the particle size of matrix has considerable influence on the polluted river water quality ...

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 ...

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.

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 ...
