A Technique for Quantifying Forest Stands for Management Evaluations

A Technique for Quantifying Forest Stands for Management Evaluations

Date: December 1971
Creator: West, Henry W. & Allen, H. H.
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

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

Date: April 1971
Creator: Rush, Edgar S. & Robinson, J. H.
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).

Deflection-Coverage Relationship for Flexible Pavements

Deflection-Coverage Relationship for Flexible Pavements

Date: June 1971
Creator: Joseph, Alfred H. & Hall, Jim W.
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).

Date: June 1971
Creator: Hoff, G. C.
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.

The Effect of Time Ordering on the Lyman α Profile

The Effect of Time Ordering on the Lyman α Profile

Date: June 1971
Creator: Godgrey, J. T.; Vidal, C. R.; Smith, E. W. & Cooper, J.
Description: Report investigating the effects of time-ordering over the complete line profile using a unified theory of spectral line broadening previously developed. The behavior of the time-ordered thermal average and un-time-ordered thermal average are compared. The Fourier transform of the thermal average is obtained analytically. Calculations for the line profile of the Lyman-[functional symbol alpha] line of hydrogen are presented and are representative in that the full thermal average is replaced by the thermal average with the electron velocity distribution approximated by f(v)=[functional symbol alpha] (v-vav) where vav is the thermal velocity for the plasma in question.

Date: 1971
Creator: McDonald, F. R.; Decora, A. W. & Cook, G. L.
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 paramagnetic shift is presented. The utility of the data in the identification of pyridine compounds found in shale-oil naphtha is demonstrated.
