The China Historical GIS project is developing a set of free tools and datasets covering the geographic space that has, at one time or another, been nominally part of China. The idea is to provide a generic digital platform for historical places that can be seamlessly integrated with a wide variety of contemporary GIS data, but which is not tied to a single data source.

substituted naphthofurans and naphthopyrans were constructed at high temperature from allyl or propargyl naphthyl ethers via claisen rearrangement in moderate to good yields. also, substituted (trimethylsilyl)-naphthofurans were synthesized from the corresponding naphtofurans.

This paper is concerned with very long-terms trends in poverty and inequality in England and Wales over the last century. It seeks, in particular, to provide a tentative quantitative answer to the question of whether relative poverty has become more or less extreme geographically (Dorling and Woodward 1996). Such a study is only possible through the application of novel methods for data analysi...

In battery systems, aqueous electrolytes are superior in ionic conductivity, interfacial wettability, safety and environmentally benign compared to organic liquids, polymers, inorganic solid-state liquid electrolytes.
