Mixing effectiveness depends on the source ndash sink structure: simulation results
(2008)
"Mixing refers to the homogenization of concentrations of passive scalars in fluids. On small scales it is dominated by diffusion and on large scales it is assisted by stirring. In the presence of scalar sources and sinks ...
Substrate preferences of Campeloma decisum and Elimia livescens: influence of species interaction and substrate tenacity.
(2001)
This investigation sought to examine if substrate choice among the freshwater operculate snails Campeloma decisum and Elimia livescens in Douglas Lake, Cheboygan County, Michigan could be explained by species interaction ...
Proteomic screening and identification of differentially distributed membrane proteins in Escherichia coli
(Blackwell Science Ltd, 2004-05)
Bacteria show asymmetric subcellular distribution of many proteins involved in diverse cellular processes such as chemotaxis, motility, actin polymerization, chromosome partitioning and cell division. In many cases, the ...
Hydrodynamics and microphase ordering in block copolymers: Are hydrodynamics required for ordered phases with periodicity in more than one dimension?
(The American Institute of Physics, 2004-12-08)
We use Brownian dynamics (BD), molecular dynamics, and dissipative particle dynamics to study the phase behavior of diblock copolymer melts and to determine if hydrodynamics is required in the formation of phases with ...
Ecological analysis of beetle (Coleoptera) density and diversity as bioindicators of accelerated succession in the UMBS FASET experiment.
(2009)
This study assessed beetle (order: Coleoptera) density and diversity as bioindicators for changes in northern Michigan forests undergoing succession. At UMBS, forests are succeeding from an aspen and birch dominated canopy ...
Cytokine expression in rat molar gingival periodontal tissues after topical application of lipopolysaccharide
(Springer-Verlag, 2001-07)
It is well known that proinflammatory cytokines produced by host cells play an important role in periodontal tissue destruction. However, the localization of the cytokines in in vivo periodontal tissues during development ...
Λ-Dynamics free energy simulation methods
(Wiley Subscription Services, Inc., A Wiley Company, 2009-08)
Free energy calculations are fundamental to obtaining accurate theoretical estimates of many important biological phenomena including hydration energies, protein-ligand binding affinities and energetics of conformational ...
Predator Effects On An Assemblage Of Consumers Through Induced Changes In Consumer Foraging Behavior
(Wiley Periodicals, Inc.Ecological Society of America, 2000-07)
