Seismic studies have found seismic scatterers with -2 to -12% shear velocity anomalies along some subducting slabs at 700-1900 km depth. The ferroelastic post-stishovite transition in subducted mid-ocean ridge basalt (MORB) has been linked these features, but compressional and wave velocities (VP VS) full elastic moduli (Cij) of Al,H-bearing stishovite high pressure remain uncertain. Here we de...

The Spontang Ophiolite complex represents the most complete ophiolite sequence amongst South Ladakh ophiolites and comprises mantle rocks (depleted harzburgites, dunites minor lherzolites) as well crustal (basalt, isotropic gabbros, layered gabbros etc.). In present study, detailed geochemistry (whole rock mineral chemistry) Sr-Nd isotopic analyses of thirty-six ultramafic- mafic samples have b...

Introdução: O carcinoma colorretal (CCR) é a terceira neoplasia com maior incidência no mundo e que mais vezes diagnosticada em Portugal. A sua pode ser controlada através de programas rastreio. plataforma BI-CSP congrega informação diversa relativa à atividade clínica nos cuidados saúde primários presente trabalho teve como objetivo verificar relação entre proporção utentes idade 50-75 anos ra...

Pyroxene is the chief reservoir of Fe 3+ in upper mantle peridotite, but experiments exploring pyroxene/melt partitioning ( D Fe3+ pyx/liq ) have been restricted to 100 kPa and pyroxene with low alumina. Here we present between clinopyroxenes (cpx) mafic melt at elevated pressures (1–2.5 GPa). Experiments were conducted f O2 buffered modulated by Ru + RuO 2 Fe-Pt alloy capsules, respectively, Δ...

Wadi Ghadir ophiolite in the Egyptian Eastern Desert, which forms northern part of Nubian Shield, is considered as one best-preserved segments Neoproterozoic oceanic lithosphere on Earth. Primary melt calculations and thermodynamic modeling new geochemical data for pillow lavas dike complexes, integrated with comprehensive petrographic investigations, are here employed to unravel geodynamic evo...

in this paper a first step in classifying the fuzzy normalsubgroups of a finite group is made. explicit formulas for thenumber of distinct fuzzy normal subgroups are obtained in theparticular cases of symmetric groups and dihedral groups.
