Cathodic protection (CP) systems using thermal-sprayed zinc anodes are employed to mitigate the corrosion process in
reinforced concrete structures. However, the performance of the anodes is improved by moisture at the anode-concrete
interface. Research was conducted to investigate the effect of hydrophilic chemical additives, humectants, on the electrical
performance and service life of zinc anodes. Lithium bromide and lithium nitrate were identified as feasible humectants with
lithium bromide performing better under galvanic CP and lithium nitrate performing better under impressed current CP. Both
humectants improved the electrical operating characteristics of the anode and increased the service life by up to three years.

Reregistration Eligibility Decision for Acephate. (Includes Acephate Facts)
Sep. 2001; 198 pp.

EPA has completed its review of public comments on the revised risk assessments and is issuing its risk management
decisions for acephate. The decisions outlined in this document do not include the final tolerance reassessment decision for
acephate; however, some tolerance actions will be undertaken prior to completion of the final tolerance reassessment. The
Agency now recommends expressing the acephate tolerances in terms of acephate per se under 40 CFR part 180.108. Residues
of methamidophos resulting from the metabolism of acephate are more appropriately placed under the tolerance expression
for methamidophos in 40 CFR part 180.315(c). In addition, the Agency recommends lowering the tolerance level for
cottonseed, as suggested by the data. The final tolerance reassessment decision for this chemical will be issued once the
cumulative assessment for all of the organophosphates is complete. The Agency may need to pursue further risk management
measures for acephate once the cumulative risks from organophosphates are considered. Additionally, since acephate degrades
to another, registered organophosphate pesticide, methamidophos, further risk management measures for acephate may be
necessary once the methamidophos assessment itself is completed.

Ablation Front Rayleigh-Taylor Growth Experiments in Spherically Convergent Geometry
Glendinning, S. G.; Cherfils, C.; Colvin, J.; Divol, L.; Galmiche, D.; Nov. 03, 1999; 36 pp.
Report No.(s): DE2002-790921; No Copyright; Avail: Department of Energy Information Bridge
Experiments were performed on the Nova laser, using indirectly driven capsules mounted in cylindrical gold hohlraums,
to measure the Rayleigh-Taylor growth at the ablation front by time-resolved radiography. Modulations were preformed on
the surface of Ge-doped plastic capsules. With initial modulations of 4(micro)m, growth factors of about 6 in optical depth
were seen, in agreement with simulations using the radiation hydrocode FCI2. With initial modulations of 1(micro)m, growth
factors of about 100-150 in optical depth were seen.
