Natural Resource Abundance and Economic Growth [PDF]
SSRN Electronic Journal, 2004 This paper explores whether natural resource abundance leads, other things equal, to slower growth rates. We distinguish between natural resource dependence (RD) and the natural resource endowment (RE). We estimate three models, using World Bank data on national capital stocks.

Hyperpolarized NMR Metabolomics at Natural 13C Abundance [PDF]
Analytical Chemistry, 2020 Metabolomics plays a pivotal role in systems biology, and NMR is a central tool with high precision and exceptional resolution of chemical information. Most NMR metabolomic studies are based on 1H 1D spectroscopy, severely limited by peak overlap. 13C NMR benefits from a larger signal dispersion but is barely used in metabolomics due to ca.

Boron-10 Abundance in Nature [PDF]
Nature, 1958 THE most reliable values for the isotopic abundance of boron-10 in naturally occurring minerals have been derived from mass spectrometer measurements. Results quoted by different workers, however, range from 18.4 to 19.9 per cent boron-10, and it is not difficult to find possible causes for the variation.
