Available in PDF, EPUB and Kindle. Book excerpt: Sources of error that have been identified on the gamma-ray soil density gauge are: (1) sensitivity to local density variations, especially at the soil surface, (2) sensitivity to soil composition, and (3) inaccurate calibration techniques. An attempt was made to solve these problems by developing for each gauge calibration models that enable stable and homogenous non-soil standards to be used for calibration. Calibration standards and calibration models for each gauge were found and tested. In the process of developing and testing the new nuclear gauge calibration model, the dual-gauge principal of compensating these gauges for variations in soil composition was discovered. The air-gap method of using this principal is explained and was optimized by using the calibration model developed in the current study.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study was to evaluate the suitability of existing instrumentation and techniques and to stimulate development of modified or new procedures to measure the amount and state of water in highway components, such as embankments, subgrades, base courses, pavements, and structures. In accomplishing this objective, the researchers conducted an extensive literature review. Those techniques that appear to be immediately applicable to highway problems were evaluated using a linear decision model for comparing instrument performance characteristics with specific moisture measurement needs. A comprehensive list of performance characteristics with which to make this comparison was compiled.

Available in PDF, EPUB and Kindle. Book excerpt: The photosynthetic process of higher plants converts carbon dioxide, water, and, light quanta into reduced sugars. The enzymes which catalyze this conversion are contained within the chloroplasts and can be thought of as split into two distinct groups. In one group are the enzymes of the IIlightll reactions, which harvest the light, oxidize water and generate two energy-rich intermediates, ATP and NADPH. These two intermediates plus carbon dioxide are the substrates for the second group, the IIdarkll reactions or Cal vi n cycle, which produce the reduced sugars. The chloroplast is completely bounded by an outer membrane. There is a separate, highly convoluted membrane system, the thyla koid system, enclosed within the chloroplast. The enzymes of the light reactions are physically associated with the thylakoid mem branes, while the Calvin cycle enzymes are free-floating within the stroma, or soluble part of the chloroplast (Fig. 1).
