Mar 14, 2025 · This note outlines methods developed by the U.S. Bureau of Labor Statistics (BLS) to distribute personal consumption expenditures (PCE) as a counterpart to the BEA distribution of Personal Income (PI) product by Fixler et al. (2017, 2020) and Gindelsky (2023).

6 days ago · The PCE price index, released each month in the Personal Income and Outlays report, reflects changes in the prices of goods and services purchased by consumers in the United States. Quarterly and annual data are included in the GDP release.

Tetrachloroethylene or tetrachloroethene (PCE) is a synthetic chemical often used as a degreaser for metal working and other specific industries. PCE has historically used by the dry-cleaning industry (aka dry-cleaner fluid) as it is highly stable, volatile, and non-flammable.

Dec 31, 1995 · Perchloroethylene (PCE) was reductively dechlorinated under anaerobic conditions in a continuous-flow, saturated soil column. The column was inoculated by a culture known to dechlorinate PCE to ethylene.

Apr 6, 2001 · Three columns were inoculated with a mixed PCE-dechlorinating culture, that was fed electron donor (pyruvate) at concentrations of 25, 100, and 250 mM. Pyruvate was fermented in all columns with essentially no methanogenic activity.

Jul 4, 2022 · PCE and TCE degradation yields an activation energy of 28 (IS), 58 and 40 kJ mol –1 (GM), and 62 and 53 kJ mol –1 (PL). Hydrogen gas production by ZVI corrosion increased by 3 orders of magnitude from 10 to 70 °C, and an increased chance of gas clogging was observed at high temperatures.

Jan 1, 2003 · The sixth and seventh columns (soil columns) were applied to evaluate the extent of PCE degradation byproducts removal in the aquifer downgradient of the oxygen-releasing material layer (oxygen barrier).

An anaerobic microbial consortium able to biodegrade saturation levels of perchloroethylene (PCE) in a column containing a source zone of PCE was examined phylogenetically to determine...

Sep 1, 2024 · The two scenarios represented the migration of PCE into either a CAC treatment zone (Column 2) or a pristine groundwater zone (Column 3), allowing a direct comparison between the soils with and without CAC, and a better examination of …

A continuous-flow anaerobic column experiment was conducted to evaluate the reductive dechlorination of tetrachloroethene (PCE) in Hanford aquifer material after bioaugmentation with the Evanite...
