The asymptotic field of mode I quasi-static crack growth on the interface between a rigid and a pressure-sensitive material
pressure-sensitive material mode I quasi-static interface crack crack-tip field asymptotic analysis
2009/9/25
A mechanical model of the quasi-static interface of a mode I crack between a rigid and a pressure-sensitive viscoelastic material was established to investigate the mechanical characteristic of ship-b...
Modeling Sea Ice as a Granular Material, Including the Dilatancy Effect
Modeling Sea Ice Granular Material Dilatancy Effect
2008/12/3
A dynamic sea ice model based on granular material rheology is presented. The sea ice model is coupled to both a mixed layer ocean model and a one-layer thermodynamic atmospheric model, which allows f...
Material Transport in Oceanic Gyres. Part I: Phenomenology
Material Transport Oceanic Gyres Phenomenology
2008/6/4
Material spreading and mixing by oceanic mesoscale eddies are analyzed in an idealized, numerical model of the wind-driven, midlatitude oceanic circulation. The main focus is on the regime with large ...
Material Transport in Oceanic Gyres. Part II: Hierarchy of Stochastic Models
Material Transport Oceanic Gyres Stochastic Models
2008/6/4
A hierarchy of inhomogeneous, nonstationary stochastic models of material transport is formulated, and its properties are described. The transport models from the hierarchy sequence provide progressiv...
Contributions of carbon and nitrogen from the Andes Mountains to the Amazon River: Evidence from an elevational gradient of soils, plants, and river material
carbon and nitrogen Andes Mountains Amazon River elevational gradient of soils plants river material
2005/5/9
We determined the carbon (C) and nitrogen (N) elemental and stable isotopic composition of riverine and terrestrial organic matter (OM), as well as the concentration of dissolved organic C (DOC), δ15N...
Hypolimnetic oxidation rates in Lake Superior: Role of dissolved organic material on the lake’s carbon budget
Hypolimnetic oxidation rates Lake Superio
2003/5/21
On average, the water column of Lake Superior is undersaturated with respect to dissolved oxygen and supersaturated with respect to carbon dioxide during the summer-stratified period. On the bas...
Quantitative and qualitative relationships between planktonic diatom communities and diatom assemblages in sedimenting material and surface sediments in Lake Baikal, Siberia
Quantitative qualitative relationships Lake Baikal Siberia
2003/5/21
Endemic planktonic diatoms are a major component of Lake Baikal sediments during interglacial periods. To
investigate how these diatom assemblages are altered during sediment formation, quantitative ...
Spectrofluorometric characterization of dissolved organic matter for indication of precursor organic material and aromaticity
Spectrofluorometric characterization dissolved organic matter indication of precursor organic material aromaticity
2001/1/30
We studied the fluorescence properties of fulvic acids isolated from streams and rivers receiving predominantly terrestrial sources of organic material and from lakes with microbial sources of organic...
