Abstract: The report describes the results of an experimental study involving the injection of a gaseous secondary jet into an unbounded supersonic flow field which was uniform outside of a turbulent boundary layer. The investigation was principally concerned with the formulation of the shock wave shapes and streamline patterns to be associated with typical turbulent, two-dimensional jet-interaction flows. In support of this objective, results are presented for a Mach 5 test conducted using a flat-plate model containing a sonic secondary jet directed normal to the main-stream. The jet-interaction flow field was primarily investigated for jet strengths (ratio of jet gas stagnation pressure to free-stream static pressure) of 180 and 550. Intermediate strengths were also studied but in lesser detail. Local flow properties were measured throughout the flow field and surface pressure distributions were recorded fore and aft of the secondary jet. From these data and complementary shadowgraph studies, the streamline pattern and attendant shock structure were formulated.

Partial abstract: "Past spawning areas (those removed from use before 1969) and present ones (those in use in 1969) are described for steelhead trout, Salmo gairdneri; coho salmon, Oncorhynchus kisutch; sockeye salmon, O. nerka; and chum salmon, O. keta" (p. 1).

From Summary and Conclusions: "After a period of tests at the Oak Ridge National Laboratory in 1966 and 1967, the Vertical Tube Evaporator (VTE) Pilot Plant was moved to the OSW's East Coast Test Station at Wrightsville Beach, N.C. In the summer of 1967 it was installed and was started in upflow operation with seawater feed, using stem and other services provided by the station. The operation of the Pilot Plant at Wrightsville Beach was performed by Stearns-Roger Corporation under subcontract to ORNL. Operation was in the upflow mode during the entire reporting period."

From introduction: In this study on raw material sources of uranium the Southern Interstate Nuclear Board has catalogued all known occurrences of uranium and some references to thorium in a 17-state area (P1. 1). These occurrences have been evaluated as potential sources of uranium by the State Geological Surveys and the consultant group of SINB. Favorability guides have been applied to the known occurrences and recommendations have been made for future action by the states involved, federal agencies, or by industry. State recommendations are included in state-by-state summaries. The state reports were written either by personnel of the State Geological Surveys or were abstracted from State geological survey data by members of the consultant group...The purpose of this study was to compile information on and systematically assess uranium and other radioactive occurrences in the region. The SINB undertook the project because of its statutory, interstate capability as an extension of government in each of the 17 states, an arrangement that lends itself effectively to this cooperative undertaking.

Report containing a methodology for determining the least expensive plan to use water from desalination plants. Elements of this methodology include treatment requirements for fresh water, sea water, and waste water, storage, conveyance, and waste water disposal.

From introduction: To improve understanding of uranium mineralization of the Todilto Limestone of Late Jurassic age in the Grants district, New Mexico, the mines active in 1957 were reviewed to determine the major types of deposits. A representative example of each type was selected and mapped in great detail to establish a prototype. It was hoped that the analysis of prototypes might shed considerable light on the mineralization process and aid evaluation of other deposits by offering a standard of comparison.
