Oceanographic Observations: North Atlantic Standard Monitoring Sections A1, A2, A3, and A4, 1967-1968

Description: Abstract: Seasonal variations in the Labrador Current are described using a defined Labrador Current Water together with geostrophic currents and salinity-temperature variations. The analysis is based on Standard Monitoring Sections occupied during 1967 and 1968 by U.S. Coast Guard cutters.

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.

Trafficability of Soils: Effects of Surface Conditions on Drawbar Pull of a Wheeled Vehicle

Description: "A study was conducted to (a) investigate the effects of soil surface conditions on one-pass drawbar pull capabilities of a wheeled vehicle, (b) relate optimum drawbar pull to soil strength as measured by several instruments, (c) develop tentative equations for predicting optimum tractive coefficient, and (d) determine effects of tire characteristics (tread pattern and deflection) on drawbar pull. One hundred and six drawbar pullslip tests were conducted with a 3/4-ton M37 truck at a gross weig… 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).

Deflection-Coverage Relationship for Flexible Pavements

Description: Summary: "This study was conducted for the purpose of developing a relationship between elastic pavement deflection and pavement performance (number of traffic applications necessary to cause failure). Data for the study were taken from past studies of airfield and highway pavements. A summary of test conditions, failure criteria, and traffic type is given for each data source. A relationship was developed between elastic deflection and the number of coverages of traffic for combined airfield a… more

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
