In a series of excellent studies, DENNIS and co-workers, 1962, have described a new method for left heart bypass without thoracotomy. A cannula was placed in the left atrium via the superior caval vein and the right atrium, according to a method described by BEVEGARD et al., 1960, where the atrial septum is punctured with a needle from the superior vena cava. DENNIS et al. used a manually regulated roller pump for the left heart bypass. ...

This paper investigates the problem of predicting gravity values in ocean areas which are sparsely surveyed. Some of the prediction techniques currently employed are summarized and a brief review of gravity reductions pertinent to this study are presented. In an effort to use accepted statistical algorithms supplemented by other supporting geophysical data, gravity prediction by the method of pseudo-density profiling is then developed. This interpolating procedure uses the correlation of free-air gravity and bathymetry to predict values in ocean areas where gravity observations are sparse but bottom topography is known in detail. An integral part of the method is optimizing the gravity/bathymetric relationship by low-pass filtering the bathymetry. Conclusions of this study are based on examples of both one- and two-dimensional applications and illustrate that under the proper conditions, the pseudo-density method produces results which are superior to other interpolation techniques. In areas where coverage is not so sparse, departure of predicted gravity from observed values provides a method for inferring lateral variations in density associated with regional geology and tectonics., Master's thesis.

The Navy Technical Manual System (NTMS) is intended to support and improve the preparation, revision, storage, distribution, management and control of Navy technical manuals. This report presents a concept for an information system which supports the creation, preparation/revision and distribution of TM materials., See also report dated 6 Jun 75, AD-A012 232.

A theoretical framework for predicting leachate quality in confined disposal facilities was developed using mass transport theory. The physical-chemical processes governing leaching were identified and described mathematically. Various approaches to describing contaminant transfer form the dredged material solids to the aqueous phase were considered, including equilibrium concepts, dissolution kinetics, intraparticle diffusion, and film effects. The approach recommended for application to dredged material uses an operationally defined distribution (partitioning) coefficient to relate aqueous phase concentration to solid phase concentration. This approach assumes equilibrium within the dredged material between solid and aqueous phases. The equilibrium approach assumes that interphase transfer kinetics are fast compared to the percolation rate of water through dredged material. A sequential batch leach test is recommended for obtaining distribution coefficients, and a pressurized column test using divided-flow (double-ring) parameters is recommended as a physical model of reduced scale for verifying the distribution coefficients obtained in batch tests. The design concepts for the laboratory tests are preliminary, and additional evaluation on the basis of actual test results will be needed before the procedures recommended can be adopted.

An evaluation of the 1965.0 epoch, H. O. 1706 World Magnetic Variation Chart is performed by direct comparison of charted and observed values. Results of this study provide an estimate of chart reliability based on the correlation of the computed spherical harmonic surface and individual field data values. (Author)
