Comparison between clasts of the Tatahouine diogenite, collected the day of the fall in 1931 and 63 years later in 1994, allows the evaluation of mineralogical and chemical effects of terrestrial residence on meteorites. Secondary minerals are found in the ...
Small angle neutron scattering experiments have been undertaken on the tempered martensitic steel EUROFER97 after proton irradiation at 250 and 350 degreesC and for doses of 0.3 and 1 dpa. It has been qualitatively shown that the scattering arises from dis ...
Ion-microprobe was used to measure Li abundances and isotopic compositions in pyroxenes from three Martian meteorites belonging to the nakhlite family. The profiles performed across augite crystals from Northwest Africa 817 show a large isotopic zoning fro ...
Biological control over coral skeletal composition is poorly understood but critically important to paleoenvironmental reconstructions. We present microanalytical measurements of trace-element abundances as well as oxygen and carbon isotopic compositions o ...
We study the effect of a violation of the strong equivalence principle (SEP) on the cosmic microwave background (CMB). Such a violation would modify the weight of baryons in the primordial gravitational potentials and hence their impact in the establishmen ...
A Nordtvedt effect at cosmological scales affects the acoustic oscillations imprinted in the cosmic microwave background. The gravitational baryonic mass density of the universe is inferred at the first peak scale from WMAP data. The independent determinat ...
We construct a class of simple and calculable theories for the supersymmetry-breaking soft terms, They are based on quantum modified moduli spaces. These theories do not break supersymmetry in their ground state; instead we postulate that we live in a supe ...
Lithium abundances and isotopic compositions were measured by ion microprobe in individual grains of pyroxene, and in a few maskelynites and Ca-phosphates grains, from the Martian meteorite Northwest Africa 480 (NWA 480). ...
This paper examines the radiation profiles and corresponding ionization source profiles of carbon and main plasma ions in matched helium and deuterium. L-mode plasmas in JET. The radiation intensities from C1+, C2+ and C3+ in the helium plasmas showed redu ...
It is well established that clusters of both vacancies and self-interstitial atoms (SIAs) are produced in displacement cascades. Ample evidence has also been presented showing that SIAs produced in the form of small dislocation loops may be highly glissile ...
