Multichannel image processing colour morphology vector ordering principal component analysis urban analysis
2015/7/30
Today, colour or multichannel satellite and aerial images are increasingly becoming available due to the commercial availability of
multispectral digital sensors and pansharpening function of the co...
Influence of lithology on hillslope morphology and response to tectonic forcing in the northern Sierra Nevada of California
Influence of lithology hillslope morphology response to tectonic forcing the northern Sierra Nevada of California
2014/5/20
Many geomorphic studies assume that bedrock geology is not a first-order control on landscape form in order to isolate drivers of geomorphic change (e.g., climate or tectonics). Yet underlying geology...
Synthesis, Film Morphology and Performance of a Functional Polysiloxane Containing Polyether, Epoxy and Trifluoropropyl Side Groups
Cotton Fabric Film Morphology Hydrophobic Property Modified Polymethyltrifluoropropylsiloxane
2011/12/20
A novel polysiloxane (PSA-PFMS) fabric finishing agent, bearing pendant stearyl acrylate, polyether, epoxy and trifluoropropyl side groups, etc., was synthesized by hydrosilylation of polytrifluoropro...
Morphology of the pore space in claystones–evidence from BIB/FIB ion beam sectioning and cryo-SEM observations
Morphology pore space claystones–evidence BIB/FIB ion beam sectioning
2009/10/22
The morphology of pore space has a strong effect on mechanical and transport properties of mudrocks and clay-rich fault gouge, but its characterization has been mostly indirect. We report on a study o...
Interrelationships of Mesozoic hybodont sharks as indicated by dental morphology preliminary results
Hybodont sharks Tooth morphology Dentition Mesozoic Phylogeny
2009/10/20
As many hybodont sharks are known solely from their teeth, this investigation approaches the phylogeny of the group with an emphasis on tooth morphology and dentitional patterns. The preliminary resul...

Crystal morphology and indicative microchemistry of kaolinite from kaolin occurrences in Alkaleri region, northeastern Nigeria.
Sediment patches, sediment supply, and channel morphology
Sediment patches sediment supply channel morphology
2014/4/8
Bed surface particle size patchiness may play a central role in bedload and morphologic re-sponse to changes in sediment supply in gravel-bed rivers. Here we test a 1-D model (from Parker ebook) of be...
Hisingerite: A Ferric Kaolin Mineral with Curved Morphology
Cation Exchange Capacity Halloysite Hisingerite Kaolinite Nontronite Transmission Electron Microscopy X-ray Powder Diffraction
2011/12/8
Abstract: Hisingerite, first described in 1810, has been variously regarded as noncrystalline, as a septechlorite, as ferric allophane, as ferric halloysite and as poorly crystalline nontronite. Hisin...
Morphology of Lead(II) and Chromium(III) Reaction Products on Phyllosilicate Surfaces as Determined by Atomic Force Microscopy
