Natural Resource Abundance and Economic Growth [PDF]

open access: bronze, 1995
One of the surprising features of modern economic growth is that economies with abundant natural resources have tended to grow less rapidly than natural-resource-scarce economies. In this paper we show that economies with a high ratio of natural resource exports to GDP in 1971 (the base year) tended have low growth rates during the subsequent period ...

¹³C NMR metabolomics: applications at natural abundance. [PDF]

open access: yesAnal Chem, 2014
(13)C NMR has many advantages for a metabolomics study, including a large spectral dispersion, narrow singlets at natural abundance, and a direct measure of the backbone structures of metabolites. However, it has not had widespread use because of its relatively low sensitivity compounded by low natural abundance. Here we demonstrate the utility of high-

Exploring the salt–cocrystal continuum with solid-state NMR using natural-abundance samples: implications for crystal engineering [PDF]

open access: yesIUCrJ, 2017
There has been significant recent interest in differentiating multicomponent solid forms, such as salts and cocrystals, and, where appropriate, in determining the position of the proton in the X—H...A—Y X−...H—A+—Y continuum in these systems, owing to ...

Natural Resource Abundance and Human Capital Accumulation [PDF]

open access: yesSSRN Electronic Journal, 2001
This study examines indicators of human capital accumulation together with data for natural resource abundance and rents in a panel of 102 countries running from 1970 to 1999. Mineral wealth makes a positive and marked difference on human capital accumulation.

Nutrient-rich submarine groundwater discharge increases algal carbon uptake in a tropical reef ecosystem

open access: yesFrontiers in Marine Science, 2023
Submarine groundwater discharge (SGD) in high volcanic islands can be an important source of freshwater and nutrients to coral reefs. High inorganic nutrient content is generally thought to augment primary production in coastal systems but when this is ...

The Influence of Distance Between Oil Palm Plantations and Forest Ecosystems on Spider Diversity

open access: yesJournal of Applied Agricultural Science and Technology, 2023
Forest conversion to oil palm plantations forms a unique agroecosystem. Forests known as a source of biodiversity are bordered by oil palm plantations with low diversity.
