Pressure-Pulse Propagation in Two-Phase One- and Two-Component Mixtures

Description: Report issued by the Argonne National Laboratory discussing the propagation velocity of pressure pulses in two-phase mixtures. As stated in the abstract, "in this study, a comprehensive analytical development of the propagation velocity of small pressure pulses is presented for bubble, annular, stratified, droplet, and slug-flow regimes. Particular attention is given to the influence of flow regime on the momentum transfer between phases" (p. 9). This report includes tables, illustrations, and … more

The Proton Nuclear Magnetic Resonance Spectra of Pyridines

Description: Report discussing the proton NMR spectra of 32 pyridines in two solvents, carbon tetrachloride and bezene-d6, are presented. The chemical-shift and differential-shift values are correlated with the substitutent position and with the solvent media. The ring protons and the protons on alkyl substituents are tabulated. The paramagnetic shift of the protons adjacent to the nitrogen is discussed, and a proposed structure for the pyridine-benzene complex that is consistent with the observed anomalous… more

Second Annual Report: Operation of the Muti-Stage Flash Distillation Plant, San Diego, California

Description: From Introduction: "The Office of Saline Water (OSW) maintains the MSF Module at the San Diego Test Facility, Chula Vista, California, for the purpose of further advancing and developing the state of art of the multistage flash distillation process and thereby reduce the cost of seawater conversion. The MSF Module has been built and operated to obtain engineering design and operating data to serve as a basis for: a. Future process development. b. Improved full scale plant design. Improved full … more

Shock-Absorbing Materials, Report 2: Cellular Concrete as a Backpacking Material

Description: Partial abstract: "The use of low-density cellular concrete, having an oven-dry unit weight of 50 pcf or less, as a backpacking material for deeply buried protective structures was studied. Cellular concrete was found to be suitable for this type of application. A number of physical properties of cellular concrete were determined to provide input to design codes" (p. 4).

A Technique for Quantifying Forest Stands for Management Evaluations

Description: "In this study, a system for describing the three-dimensional geometry of trees and stands is presented. The system consists of two survey instruments, a theodolite and transit, and basic triangulation principles. A spotting laser has recently been added to the system to facilitate the spotting of the tree nodes to be surveyed" (p. ix). Results show significant differences in tree productivity as a result of fertilization and changes in heights, bole diameters, etc.

Third Report on Horizontal-Tube Multiple-Effect Process Pilot Plant Tests

Description: From Summary: "This report describes the continuing work on HTME distillation plants, the first portions of which were reported in References 1 and 2. A major purpose in the testing of the three-effect pilot plant was to demonstrate mutiple-effect operability of the the horizontal tube method, when utilizing basically the same construction methods and materials as those proposed for commercial HTME plants."
