The Tagish Lake chondrite and the interstellar parent body hypothesis

Investigation of the solvent extractable organic compounds in Tagish Lake. The results are used to test the interstellar parent body hypthesis for the origin of extraterrestrial organic matter

Dual isotopic composition of methane in Murchison meteorite

Dual isotopic composition (H and C) of methane extracted from a small sample of Murchison meteorite reveals a deuterium enrichment for this molecule, indicating the presence of interstellar hydrogen

Macromolecular organic acids in the Murchison meteorite

This study has detected bound organic acids within the Murchison meteorite organic macromolecule. Benzoic acid was the most abundant compound; other abundant compounds include C1 and C2 benzoic acids. Their origin and significance will be discussed

Some evidence of purchasing power parity

Empirical support for purchasing power parity is mixed with results dependent on the time frame and countries under examination, the methodology employed, attempts to control for aggregation bias in the data, and whether adjustments are made to account for productivity differences across nations. As a central component of macroeconomic thinking, purchasing power parity is battered and battle-worn. Using methods that allow for breaking means and trends, this research note provides irrefutable evidence in favor of purchasing power parity for a wide range of countries since the late 1800s. The results suggest managers can consider purchasing power parity a long-term anchor around which they can build their strategic plans

Hydrogen isotopic composition of the Tagish Lake meteorite: comparison with other carbonaceous chondrites

A study into the hydrogen isotopic characteristics of whole rock samples of carbonaceous chondrites and their comparison with a whole rock sample of the Tagish Lake meteorite
