There are several publications that list, in tabular form, the coal resources or the coal reserves of the world, subdivided by continent, region, or country. In all of these the authors collect the best information that is available and attempt to report all values on the same bases so ...

The majority of chrysoprase is mined from commercial lapidary rough mines in Australia, but fine examples of the material are also known from Poland, Albania, Kazakhstan, Tanzania, and Oregon. It is a relatively rare stone worldwide so having an opportunity to find it is certainly unique. In ...
The drama in it comes from delicate internal moments like walking home, alone and lovestruck, after a party, the way it often does in real life, at least for the kind of people who tend to listen to melancholic acoustic pop music that is heavy on the I-IV chord progressions and ...

While regression analysis can capture nonlinearity, it does not account for multi-factor synergism (Li et al., 2024). Consequently, quantifying the complex relationships between multiple factors and vegetation change remains challenging. The Geo-detector model (GDM), as a spatial analysis tool for ...
