A series of tests was run on influent to the waste treatment facility, using various polyelectrolytes and organic polymeric coagulant aids. The influent wastewater originates in chemical process areas, janitorial sinks, process-area locker room showers, floor drains, and from the laundry. Previous tests on this waste had shown that Fe{sup +3} and Ca{sup +2} at pH 11.3 gave improved product quality. However, a suitable coagulant aid for use at high pH`s was needed to obtain a rapid settling rate in the flocculation/sedimentation process. Results of the tests showed that Nalco-C627 gave a good decontamination factor while yielding rapid settling rates. Betz-1175 gave the best decontamination factors; however, its settling rate needs to be improved. Test results revealed decontamination was greater at pH 11.3 than at pH 10.1. It is recommended at this time, that Nalco-C627 be used with the Fe{sup +3}, Ca{sup +2} high pH system, and that further tests be performed on the Betz-1175.

The Laboratory for Nuclear Science has continued its study into the feasibility of networks, changing the focus of the investigation from the possible ways of collaborating with the MIT Information Processing Center in implementing a connection to the ARPA net to a wider consideration of the implications of computer resource sharing via networks. This report describes experiments performed on the ARPA net in collaboration with the Lawrence Berkeley Laboratory and experiments in more conventional forms of remote job entry to that site and others in ERDA. It discusses the use of the Multics mail as set up for ERDA, comparing it to other mail systems. Plans for future experiments in the ARPA net and for investigation of networks other than the ARPA net are proposed. The conclusion was reached that resource sharing via networks is both feasible and desirable provided certain interface problems are solved. Recommendations are made for more investigation into the human factors involved in network use, methods of providing consulting help to users, and determination of the most cost effective use of remote resource sharing. For the Laboratory for Nuclear Science, it is concluded that access to other ERDA computers via networks will meet some of our …

The kinetics of the Li electrode in LiOH(aq) was investigated. Electrode polarization was measured by voltammetric techniques. Graphs show the following results: anodic limiting current density increases with flow rate; limiting current density depends on flow rate and bulk electrolyte concentration; and electrode resistance is weakly dependent on flow rate. An intuitive model of mass transport-limited dissolution appears to be substantiated. The following tentative conclusions were reached: an upper limit to the rate of discharge of a lithium--water battery anode will be set by the mass transfer limitations of the flow system, and not by the kinetics of the charge transport within any microscopic surface films on the anode; the resistance of the anode surface film in the linear polarization region is quite low and essentially independent of flow rate; the plane parallel electrode geometry results in as low an electrode resistance as any so far investigated and should be considered for automotive battery design. 3 figures.

The work reported in this progress report is focused on determining the proper scope of a regional assessment study program suitable for BER/ERDA. Within the tentative scope selected, a tentative set of purposes, goals, and objectives is identified for a preliminary specification of a geographical region. The initial specification of the region includes the states of Pennsylvania, New Jersey, Delaware, Maryland, and Virginia. The tentative scope of considerations for the regional assessment study program encompasses the interacting facets of environment, energy, and economic well-being of the region with the overarching goal of reconciling these facets within the decision framework of the region.

Applications of 10 to 40 ppM chlorine were ineffective in control of Asiatic clams that had colonized the suction well of a cooling water pump for one of the Savannah River production reactors. Accumulated mud on the floors and walls of the basin protected large numbers of clams from lethal chlorine exposures. After clams were removed from chlorine exposures of 9, 17, 25, and 54 hours, respective survivals after seven days in a recovery chamber were 97 percent, 84 percent, 47 percent, and 10 percent. Of the clams that were protected by mud during the entire test (54 hours), 65 percent were alive after seven days in the recovery chamber. (auth)

The increasing importance of Nd glass lasers in laser fusion technology has emphasized the inadequacy in the understanding of the optical properties of rare earth ions in glasses. Indeed, it has been difficult to generate models for the performance of these devices, and the selection of host glasses could be done by little more than a trial-and-error approach. The technique of laser-induced fluorescence line-narrowing developed within the last few years provides a new and powerful tool for the study of these systems. In this technique, a laser excites within the inhomogeneously broadened absorption bands a selected subgroup of the ions in the system, namely those whose absorption energy is resonant with the laser. If the excitation does not migrate among the entire collection of ions prior to fluorescence, the fluorescence that is observed is only from the group that was excited and is narrowed. This permits the selective study of classes of ion sites within the ensemble. The concept is indicated schematically. By the use of a tunable laser, such as a dye laser, it is possible to vary the class of sites, defined by energy, that is excited and thereby study the important spectroscopic properties and their variations, unclouded …

Abstract: The Air Launched Balloon System (ALBS) development history is traced and the circumstances leading up to planned ALBS flight tests are described, including a report on successful tests of the cryogenic storage subsystem. The theoretical performance of a candidate parachute development system--35-ft (10. 67 m) diameter ring sail drogue, 64-ft (19.51 m) diameter flat circular main chute--is mathematically analyzed using a number of stated assumptions. Contingency arrangements (e.g., use of ballast) and their impact are discussed. Data indicate that the ALBS mid-air deployment concepts require experimental proof-of-concept testing to ensure optimum component selection. Parachute subsystem verification tests planned for the autumn of 1976 at El Centro, Calif., are outlined along with plans for partial and complete ALBS system test drops from a carrier balloon in 1977 at White Sands Missile Range.
