Paul O’Flinn). As expected, trace elements in coal (Chapter 2) are found enhanced in flyash by a factor related to the ash yield of the coal. For dry bottom furnaces, 100 t coal yields an amount of flyash equal to about 0.8 times the % mineral matter which is close to 0.8 times the % ash yield at about 800°C. T

Gary Daydioecious and has external fertilization, the eggs developing into pelagic veligers which remains planktonic for approximately 4 weeks. Gametogenesis begins in late winter to early spring, veligers appear in the water column in late May to early June and disappear in mid to late October in Lake St.

Graham Dawson a moderate organic load (mean TOC ~290 µmol L., and mean yield ~10.5 mmol m. y.; ~60% accounted for by DOC). Suspended sediment yield at Los Altares (~14 T km. y.) and in the lowermost reach (~25 T km. y.) indicate a relatively low denudation. The alteration index of riverbed sediments (mean CIA ≈
