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 weight of 7240 lb. One tire size (9.00-16, 8-PR), two tread patterns (smooth and nondirectional military), and two tire deflections (15% and 35%) were tested. Surface conditions varied from dry and firm, to wetted with small amounts of water, to flooded. Asphalt surfaces also were tested" (p. xi).

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.

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 and highway data and for airfield data only. The relationship of wheel load and tire pressure is given, and a multiple-regression equation was determined to predict coverages as a function of wheel load, tire pressure, and deflection" (p. xi).

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).

Transport-Depletion Desalination Pilot Plant

Description: From Summary: "The transport-depletion data obtained by the Southern Research Institute and by the Bureau of Reclamation at Denver, Colorado and at Webster, South Dakota, was reviewed. This data review made it possible to develop a design methodology for the pilot plant, and to identify the additional data required to adequately predict the performance of a transport-depletion stack."

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."

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 scale plant operating conditions."

Operation of the Multi-Effect Multi-Stage Flash Distillation Plant (Clair Engle), Fourth Report (Semi-Annual), San Diego, California

Description: From Summary, Conclusions, and Recommendations: "The operation and development programs carried out in the CEP, E-1A and LMC plant during the period July 1, 1970 to December 31, 1970 are described in this report. Data was developed on several development tasks as follows. A summary is presented of material evaluation studies made over the past three and a half years. Data on the experiences with coatings, mortar linings, elastomers, and nonferrous and ferrous metals are included. Details are presented of coatings and linings installed in the CEP II Effect including methods of surface preparation and costs."

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 a photograph.
