Morphology, microstructure, crystallography, and chemistry of distinct CaCO3 deposits formed by early recruits of the scleractinian coral Pocillopora damicornis

Anders Meibom, Duncan Thomas Lindsay Alexander, Jaroslaw Hubert Stolarski, Melany Melissa Gilis

ABSTRACT Scleractinian corals begin their biomineralization process shortly after larval settlement with the formation of calcium carbonate (CaCO3) structures at the interface between the larval tissues and the substrate. The newly settled larvae exert var ...

Redox variations and bioproductivity in the Ediacaran: Evidence from inorganic and organic geochemistry of the Corumba Group, Brazil

Mariluz Bagnoud

Stable isotope ratios combined with elemental compositions and molecular biomass data provide a powerful tool in Neoproterozoic palaeoenvironmental interpretations. Here, we report the results of an extensive organic and inorganic geochemical study perform ...

Poroelastic behavior of Calcarenite for the purposes of geologic CO2 storage

Lyesse Laloui, Roman Makhnenko

Geologic CO2 sequestration is considered to be the most promising technique to reduce the concentration of greenhouse gases in the atmosphere. Among all the storage options, deep saline aquifers have the greatest potential and due to their worldwide occurr ...

Stable isotope (S, C) chemostratigraphy and hydrocarbon biomarkers in the Ediacaran upper section of Sierras Bayas Group, Argentina

Mariluz Bagnoud

The Neoproterozoic sedimentary successions of the Sierras Bayas Group (SBG) are situated within the Tandilia Belt, Buenos Aires Province, Argentina. The Loma Negra Formation (LNF) from the upper part of the SBG has been investigated using a combination of ...

Understanding Soft-Tissue Behavior for Application to Microlaparoscopic Surface Scan

Mustafa Suphi Erden

This paper presents an approach for understanding the soft-tissue behavior in surface contact with a probe scanning the tissue. The application domain is confocal microlaparoscopy, mostly used for imaging the outer surface of the organs in the abdominal ca ...

Sediment Suspension Dynamics in Turbulent Unsteady, Depth-Varying Open-Channel Flow over a Gravel Bed

Fereshteh Bagherimiyab Hunkeler

Even though flow in natural rivers and channels is generally unsteady, only a few studies on turbulent structures in unsteady open-channel flows have been carried out. In hydraulic engineering problems, unsteady flow is often approximated with concepts of ...

Impacts Of Sand Transport On Flow Variables And Dissolved Oxygen In Gravel-Bed Streams Suitable For Salmonid Spawning

Mário Jorge Rodrigues Pereira Da Franca, Ana Margarida Da Costa Ricardo

Increased sediment production resulting from the erosion of unprotected soil in a catchment may result in severe changes in the morphodynamics and hydrodynamics of mountain rivers. Sediment overfeeding can lead to the degradation of salmonids' spawning sit ...

NanoSIMS: Insights to biogenicity and syngeneity of Archaean carbonaceous structures

Anders Meibom, François Robert

NanoSIMS is a relatively new technology that is being applied to ancient carbonaceous structures to gain insight into their biogenicity and syngeneity. NanoSIMS studies of well preserved organic microfossils from the Neoproterozoic (similar to 0.8Ga) Bitte ...

Spatial analysis of karst conduit networks and determination of parameters controlling the speleogenesis along preferential lithostratigraphic horizons

Marco Filipponi

The main objective of this thesis is to improve the understanding of the position and characteristics of karst conduits within a rock massif. Such a characterisation is an important issue in civil engineering and in hydrogeology. Today in practice dissolut ...

Polymer brushes as ionotropic matrices for the directed fabrication of microstructured calcite thin films

Harm-Anton Klok, Stefano Tugulu

(Figure Presented) How to get into films: Micropatterned poly(methacrylic acid) (PMAA) brushes are used as an ionotropic matrix for the fabrication of microstructured calcite thin films. The calcite films are an exact 3D replica of the PMAA brush matrix (s ...
