Presolar Grains from the Qingzhen (eh3) Meteorite

A 28 g sample of the Qingzhen enstatite (EH3) chondrite was subjected to chemical and physical separation procedures to yield several grain-size residues. Ion mapping of isotopes of Si, O, and C in the ion microprobe of two size fractions (QZR4: 0.4–0.8 lm; QZR5: 0.8–2 lm) identified 55 30Si-depleted candidates out of 37,917 Si-rich grains and six 18O-depleted grains out of 54,410 oxides. Subse...

Sodium-22 from Supernovae: a Meteorite Connection

There are several meteoritic noble gas components whose isotopic abundances are distinctly different from the solar abundance. One of these components, Ne-E(L), is a 22Ne-rich component carried by presolar graphite. Neon-22 is dominantly from the radiogenic decay of 22Na (T1/2 = 2.6 a), but it also contains 22Ne produced by 14N(α, γ )18F(e+ν)18O(α, γ )22Ne. The proportions of 22Ne from the two ...

Spatially Enabling Government: a Snapshot from Victoria

A spatially enabled government manages its information and processes using spatial concepts and technologies. The vision gained traction in the mid 2000s and has been the focus of international forums including GSDI and PCGIAP. This paper aims to review the status of the vision by presenting the results of qualitative and quantitative studies undertaken into the spatial capacity of the Victoria...

Alleged Scientific Consensus

Most of the literate world today regards "global warming" as both real and dangerous. Indeed, the diplomatic activity concerning warming might lead one to believe that it is the major crisis confronting mankind. The June 1992 Earth Summit in Rio de Janeiro, Brazil, focused on international agreements to deal with that threat, and the heads of state from dozens of countries attended. I must stat...
