The Moon as a High Temperature Condensate,‘enrichment’ in Ca, Al, Ti, U, Th, Ba, Sr and the REE and the ‘depletion’ in Fe, Rb, K, Na and other volatiles can be understood if the Moon represents a high temperature condensate from the solar nebula. Thermodynamic calculations show that Ca, Al and Ti rich compounds condense first in a cooling n

,Introduction: ‘Trans-Scripts’,uring acceleration and emission (by analogy with solar particle emission), and highly evolved matter enriched in .-process elements such as U, Th and transuranic elements. The energy-dependence of cosmic ray composition suggests that both sources may contribute at different energies.

Towards an Intercultural Approach to Social Cohesioniated with new migration over the past two decades. A paper published in 2007 by Robert Putnam reignited the debate with the claim that immigration and diversity has a universally negative effect on social cohesion. This paper argued that increasing diversity is associated with weaker social network
