Cumulative Vols

Well Injectivity. Barkman and Davidson (2) were among the first to model injectivity decline due to foreign solids invasion. They considered that after a specific period of time, known as the bridging time, the decline in injectivity is due to filter cake formation only. According to the filtration theory, the cumulative volume is proportional to square root of filtration time, provided that the pressure drop across the filter remains constant. Figure 14 shows the variation of the cumulative vol-...

Registry Numbers. Annual supplements, with cumulative indexes, have appeared since 1983. A similar work, devoted to organometallic compounds, is the 2nd edition of the Dictionary of Organometallic Compounds , 6 vols. in its 5th supplement, published by Chapman and Hall in 1989. Another, Dictionary of Steroids , 2 vols., 1991, is also published by Chapman and Hall. 

Organic Syntheses, published by Wiley, New York is a collection of procedures for the preparation of specific compounds. The thin annual volumes have appeared each year since 1921. For the first 59 volumes, the procedures for each 10- (or 9-) year period are collected in cumulative volumes. Beginning with vol. 60, the cumulative volumes cover five-year periods. The cumulative volumes published so far are...
