Synergistic capture mechanisms for alkali and sulfur species from combustion
This report presents work done on a laboratory combustor in an attempt to identify mechanisms that govern the simultaneous capture of alkali and sulfur species using sorbent injection techniques. The mechanisms of capture fall into two broad categories i.e. Physical transport of alkali species (in vapor or condensed phase) to the sorbent surface and surface reaction between the alkali species and the sorbents. Water solubility, though not specific, has been used to get an indication of relative significance of these two broad mechanisms. It is assumed that the physically adsorbed alkali species on sorbents are predominantly water soluble while the chemically reacted alkali content is predominantly water insoluble. In order to infer possible dominant mechanisms, specific parameters has been varied during experimentation. Such parameters include, speciation, particle time-temperature history, and furnace burning conditions.

Social Security Administration: Old-Age, Survivors, and Disability Insurance and Supplemental Security Income for the Aged, Blind, and Disabled; Substantial Gainful Activity Amounts
Other written product issued by the General Accounting Office with an abstract that begins "Pursuant to a legislative requirement, GAO reviewed the Social Security Administration's (SSA) new rule on Old-age, Survivors, and Disability Insurance and Supplemental Social Security Income for the aged, blind, and disabled. GAO noted that: (1) the rule would revise the monthly earnings guidelines for determining when earnings demonstrate the ability to engage in substantial gainful activity (SGA); (2) specifically, the final rule raises from $500 to $700 the average monthly earnings guidelines used to determine whether work done by persons with impairments other than blindness is SGA; and (3) SSA complied with the applicable requirements in promulgating the rule."

Partitioning between sediment and porewater of radiocesium from Chernobyl fallout
As part of a joint USA/USSR Environmental Agreement to determine the distribution and concentration of Chernobyl radioactivity in the northwest Black Sea area, the sediment from eight stations was collected and analyzed to assess the ability of sediment from the northwest Black Sea to adsorb radiocesium. Two methods were used to determine partitioning between liquid and solid phases; batch tests and porewater separation. In the batch test, Cs-137 tracer was added to mixtures of sediment and bottom water, with contact solutions ranging from 85 Bq/ml to 1760 Bq/ml. The distribution ratios (R{sub D}) for individual batch tests ranged from 390 to 1770 ml/g. Isotherms were linear for all cores and R{sub D} values calculated from the slopes of the isotherms ranged from 660 to 1660 ml/g. A second approach was used to determine the partitioning of Cs-137 between the porewater and the sediment under more natural conditions. The top 2 cm of two cores were sectioned and the sediment and the porewater were separated. In both samples the sediment contained significant amounts of Cs-137 and Cs-134 indicating the presence of fallout from the Chernobyl reactor accident. There was no cesium activity observed in the porewater at a minimum detectable level …
