Context. Structural parameters of model star clusters are measured in radial profiles built from number-density, massdensity and surface-brightness distributions, assuming as well different photometric conditions. Aims. Determine how the core, half-star count and tidal radii, as well as the concentration parameter, all of which are derived from number-density profiles, relate to the equivalent ...

Over the last two decades, marine science, aided by technological advances in sediment coring, geophysical imaging and remotely operated submersibles, has played a major role in the investigation of contemporary and former ice sheets. Notable advances have been achieved with respect to reconstructing the extent and flow dynamics of the large polar ice sheets and their mid-latitude counterparts ...

The aim of this work was to relate depth profiles of prokaryotic community composition with geochemical processes in the deep subseafloor biosphere at two shallow-water sites on the Peru Margin in the Pacific Ocean (ODP Leg 201, sites 1228 and 1229). Principal component analysis of denaturing gradient gel electrophoresis banding patterns of deep-sediment Bacteria, Archaea, Euryarchaeota and the...

Using a complex of remote and surface geophysical methods in the eastern part East European Platform, regional meridional heterogeneitieswere revealed; it isshown that these heterogeneitiescan becaused by low-density magnetically active rocks thecrystalline crust mantle. The totality geological data indicates relationship heterogeneities with transcontinental deep faults.

Besides common implant techniques, dopant diffusion enables steep diffusion profiles in heavily doped deep-source drain and ultra-shallow junctions as required in advanced microelectronic technology. Experimental phosphorus dopant diffusion profiles in silicon are described by a rational function diffusion (RFD) model, based on direct solution of Fick’s equations and suitable for actual work in...

In the forearc region, aqueous fluids are released from the subducting slab at a rate depending on its thermal state. Escaping fluids tend to rise vertically unless they meet permeability barriers such as the deformed plate interface or the Moho of the overriding plate. Channeling of fluids along the plate interface and Moho may result in fluid overpressure in the oceanic crust, precipitation o...

SUMMARY This Ph.D. thesis focuses on construction and analysis of a comprehensive model of the European lithosphere, which is based on the integration of most of the existing geophysical studies and estimation of physical (density, temperature, velocity) and rheological parameters. The model describes the structure and physical properties of the principal lithospheric layers, drawing special at...

The central Oregon section of the Cascade Range volcanic arc is characterized byrelatively high Quaternary volcanic extrusion rates and hot-spring discharge rates, and by high conductive h at flow. However, a large area of near-zero near-surface onductive h at flow occurs in the younger volcanic rocks, due to downward and lateral flow of cold groundwater. Alternate models for the high heat flow...
