S — Incompatible Trace Elements in SNCs and Li Isotopes Systematics in a Shergottite J. A. Barrat, P. Beck, M. Chaussidon, Ph. Gillet, A. Jambon, C. Göpel, and V. Sautter Exploring Trace Element and Isotopic Mixing Relationships in the Martian Meteorite Suite

a good understanding of adsorption equilibrium and thermodynamics is required to design and operate an adsorption process. this study was conducted to assess the adsorption percentage of pb2+ ions as a function of contact time, solution ph and temperatures, and adsorbent dosage through a series of batch experiments. the methods including zeta potentials, specific surface area measurements and t...

Use of earthworm species to biodegrade various substrates (industrial wastes, agricultural residues, etc.) for composting has proven to be successful after initial stabilization of vermi beds. This study presents optimization of vermi beds (soil + cowdung) for culturing of earthworms (Eisenia fetida, Eudrilus eugeniae, and Megascolex megascolex.). Optimum proportion of soil + cowdung (1:3) for ...

Steingrimsson and Luce (2003a) outlined the second author’s proposed psychophysical theory (Luce, 2002, 2003a,b) and tested behavioral attributes that, separately, gave rise to one psychophysical function, Ψ, that maps pairs of physical intensities onto the positive real numbers that represents subjective summation and a second one, Ψ∗,that represents a form of ratio production. This article ta...
