The objective of this work is to investigate, in the laboratory, the parameters associated with a chemically assisted in situ recovery procedure, using hydrogen chloride (HCI), carbon dioxide (CO{sub 2}), and steam (H{sub 2}O), to obtain data useful to develop a process more economic than existing processes and to report all findings. The technical progress of the project is reported. The project status is that the solutions to the problems discussed in the third quarter status, were found to function satisfactorily. Future needs have been considered, and appropriate equipment and instrumentation changes have been designed. Only one experiment was performed this quarter, with some improvement over the previous experiments. The increase in shale oil recovery followed directly from the changes discussed last quarter, but the improvement could have been larger with wider-spread implementation of the changes. Equipment was purchased to rectify the need, and will be installed shortly. Further, a minor change in the design was necessary to account for the brittleness of high temperature electrical resistance heating tapes. The focus of the work this quarter has been on the development of computer software to enable the use of on-line parameter identification, the design of the instrumentation necessary to adequately …

The polycrystalline nature of thin-film CdTe and CuInSe{sub 2} solar cells continues to be a major factor in several individual losses that limit overall cell efficiency. This report describes progress in the quantitative separation of these losses, including both measurement and analysis procedures. It also applies these techniques to several individual cells to help document the overall progress with CdTe and CuInSe{sub 2} cells. Notably, CdTe cells from Photon Energy have reduced window photocurrent losses to 1 mA/Cm{sup 2}; those from the University of South Florida have achieved a maximum power voltage of 693 mV; and CuInSe{sub 2} cells from International Solar Electric Technology have shown a hole density as high as 7 {times} 10{sup 16} cm{sup {minus}3}, implying a significant reduction in compensation. 9 refs.

Quarter summary: all modifications previously planned where completed and a reaction experiment was run. A couple design flaws were discovered, improvements were designed, and all parts are expected in the first week of July. Experiment {number_sign}6 is expected to run the following Monday. Barring further mishap, experiments will be run one each week thereafter. The project is behind schedule, but the project is well positioned to make significant and considerable progress.

He discusses his childhood in West Texas; joining the CCC; assignment to Company 3892 camp at the Colorado National Monument (NP-8-C) near Grand Junction, Colorado; transfer to a side camp in Glenwood Springs, Colorado; description of camps; life in camps.

Interview with James Gipson concerning his experiences before, during, and after his employment in Civilian Conservation Corps during the Great Depression. Gipson worked at camps in Grand Junction, Colorado and Glenwood Springs, Colorado.

Interview with Harold L. Trammell, a member of the Civilian Conservation Corps from Mason, Oklahoma. Trammell discusses his early life, train hopping to Utah and back, enrollment in the CCC at Fort Sill, his assignment to Cache, Oklahoma, building trails in the Wichita Mountains Wildlife Refuge, work at Arapaho National Forest in Colorado, pranks in camp, daily routine, entertainment and recreation, drinking, discipline, and life after the CCC. In appendix is a copy of Trammell's account of his time in the CCC, and the May 30th, 1935 edition of the CCC magazine "Panther Tracks."

Photograph of a ping pong table in a recreation room. Two faint, ghostly figures play ping pong at the table. There is an arcade machine to the left of the table and an unidentified machine to the right. There is a mural on the room's back wall depicting four people in a car, two of them sticking out of the car's hood. Another set of people roller skates in the right half of the mural.

A large component of radon entry cannot be explained by pressure differences between the soil and inside the structures. The persistence of this radon entry even when the house is pressurized by 1 Pa indicates that it must be due to molecular diffusion. The radon entry rate as measured by accumulators below ground level (soil + concrete) is roughly 2 times greater than that measured above ground level (concrete alone). The soil permeability is about 10{sup {minus}12} m{sup 2} and does not change dramatically with depth down to 2 m. The diffusion component of radon entry is reduced by about 30% when the floor wall joint is sealed. The Rn3D model is operating on our computer system and is being modified to accommodate the geometrical configurations of the underground test structure.

A report about new geochemical, biogeochemical, and sedimentological data gathered from the depositional basins of the Green River Formation.

From abstract: Middle Cretaceous rocks (Aptian to Coniacian) on the south side of the Uinta Basin include the nonmarine Cedar Mountain Formation and Dakota Sandstone and the lower part of the overlying marine Mancos Shale. This report examines the rocks contained within this area of the basin.
