Changes in concentrations of several of the organic constituents of the waste leachate samples were observed due to anaerobic microbial activity. Mixed bacterial cultures isolated from the trench leachates were able to grow anaerobically in trench leachates, which indicates that the radionuclides and organic chemicals present were not toxic to these bacteria. Kutsuki, Katsuhiro Kawaji, Sachiko Watanabe, Yukihiko Onishi, Toru Fujiwara, Hirokazu Yamamoto, Kensaku Yamamoto, Toshimasa Temperature characteristics of the channel mobility were investigated for 4H-SiC trenched MOSFETs in the range from 30 to 200 ☌. The data will be used to refine morphological model predictions to include variations in grain size and associated shallow stratigraphy.
These data provide a first-order, quantitative examination of the small-scale temporal and spatial variability of shallow grain size along an open, sandy coastline. The elevations of coherent stratigraphic layers, as revealed in vibracore-based fence diagrams and trench data, are used to relate specific observed stratigraphic sequences to individual storm events observed at the FRF. In addition, two 1.5m deep trenches were dug in the cross-shore and along-shore directions (each 14m in length) after coring was completed to allow better interpretation of the stratigraphic sequences observed in the vibracores. Long range scanning mechanism with tilt-adjustment stage is adopted for the purpose of adjusting the probe-sample relative angle to compensate the non-parallel effects. Ju, Bing-Feng Chen, Yuan-Liu Zhang, Wei Zhu, Wule Jin, Chao Fang, F Z A compact but practical scanning tunneling microscope (STM) with high aspect ratio and high depth capability has been specially developed. The trench is now managed by Waste Tank Operations. Liquid effluent discharge to the 216-B-63 Trench began in March 1970 and ceased in February 1992.
The 216-B-63 Trench, located at the Hanford Site in south-central Washington State, is an open, unlined, earthern trench approximately 1.2 m (4 ft) wide at the bottom, 427 m (1400 ft) long, and 3 m (10 ft) deep that received wastewater containing hazardous waste and radioactive materials from B Plant, located in the 200 East Area. This is a revision of the initial groundwater monitoring plan prepared for Westinghouse Hanford Company (WHC) by Bjornstad and Dudziak (1989).
