detail exactly how sparse medical care was in Scotland. Even if it were available, the authors show that the stringency of the Scottish Poor Law may have denied access to it. One of their tables (9.B) "shows how much was actually spent on doctors per head of the population on the poor roll. The Scottish average was £0.0 154, or no more than 3.d per pauper per year in the old money" (p. 217). Th...
The most widely used superconducting materials are based on Nb-Ti alloys with Ti contents ranging from 46-50 weight % Ti. These alloys of Nb and Ti have both high strength and ductility and can be processed to achieve high critical current densities that make them ideal candidates for magnet and applications. Nb-Ti based superconductors are commercially produced in long uniform lengths and cost...
Magnesium production is considered to be one potential source of unintentional persistent organic pollutants (unintentional POPs). However, studies on the emissions of unintentional POPs from magnesium metallurgy are still lacking. Emissions of unintentional POPs, such as polychlorinated dibenzo-p-dioxins/dibenzofurans (PCDD/Fs), dioxin-like polychlorinated biphenyls (dl-PCBs), polychlorinated ...
