A cultured strain of Isochrysis galbana UTEX LB 2307 was grown at 20°C and 15°C under salinity of 35‰, 32‰,
27‰, 20‰, and 15‰, and analyzed for long chain (C37–C39) alkenones and (C37–C38) alkyl alke...

Magnetite magnetotactic bacteria Size distributions twinning
2012/4/1
We studied intracellular magnetite particles produced by several morphological types of magnetotactic bacteria including the spirillar (helical) freshwater species,Magnetospirillum magnetotacticum,and...
A reevaluation of crystal-size distributions in chromite cumulates
reevaluation crystal-size distributions chromite cumulates
2012/4/9
Although studies have shown that igneous cumulates can form byin situ crystallization without requiring crystal settling, it has not been demonstrated that crystal-size distribu-tions (CSDs) are consi...
Cathodoluminescence of quartz from sandstones: Interpretation of the UV range by determination of trace element distributions and fluid-inclusion P-T-X properties in authigenic

Quartz overgrowths from Keuper sandstones of the Paris basin wereexamined using cathodoluminescence (CL) microscopy and spectroscopy coupled witha scanning electron microscope (SEM). Withthe use ofsta...
Clay Distributions in Recent Estuarine Sediments
Clay Distributions Recent Estuarine Sediments
2011/11/18
Abstract: The distribution of clay minerals in Recent sediments can be explained by the relative stability of the clays. The rates of particle aggregation for three clays were determined in the labora...
Abstract: A knowledge of the distribution of pore sizes in clay and soil bodies is a useful element in the microstructural characterization of such materials. Pore-size distributions and total porosit...
