Estimating Cleanup Costs for Oil Spills

The factors that affect cleanup cost are complex and interrelated. Each spill involves a unique set of circumstances that determine cleanup cost. Estimating a universal per-unit cleanup cost is essentially meaningless without taking into consideration factors such as location and oil type, which can profoundly influence costs. This paper examines the host of factors that impact cleanup cost in ...

n page 765, Ohzeki et al. present evidence for sequence specificity in assembling chromatin at mammalian centromeres. The sequence requirements imply that construction of centromeric chromatin is more than an epigenetic process. O Centromeric chromatin assembles at AT-rich repeats called ␣ satellite sequences, or alphoids. Type I alphoids contain boxes for the binding of CENP-B, one of several ...

-The effect of exogenous and endogenous prostaglandins on the patterns of growth and differentiation of Friend erythroleukaemia cells (FLC) were studied. During the differentiation process, DMSO stimulated PGE synthesis by an average of 95o%. The addition of a long-acting synthetic analogue of PGE2, 16,16-dimethylPGE2-methyl ester (di-M-PGE2) to the culture medium only slightly and temporarily ...
