Abstract: The compressive and tensile properties of polyester polymer and polymer concrete were studied under various curing conditions, temperature, and strain rate. The curing temperature was varied from room temperature to 80°C. ...

Abstract: Inherent in the history of the engineering profession has been constant advance in its methods of carrying out its tasks and ever-improving quality of its work output. In this country, it has ...

Abstract: A previous study by the author of January temperatures in the mid-stratosphere at several arctic stations near 80W has been extended to include stations in other sectors of the Arctic and the additional months of December ...

Abstract: Revised means, frequency distributions and other statistics based on ten years of January temperature observations at the 200-, 100- and 50-mb levels are presented for four arctic stations. The frequency distributions are ...

Abstract: Some effects of the western mountain complex of North America on cyclones are investigated from the standpoint of how the vorticity tendency field might be influenced by orographically-induced vertical motion and divergence. ...

Abstract: Irregularities in sea-surface sunglint patterns have been frequently noticed in photographs from earth-orbiting satellites. High-resolution color photographs from low-altitude manned spacecraft missions have shown small-scale ...

Abstract: Multi-window infrared measurements, together with visual channel observations, enable relatively high-resolution and accurate local, regional, and global retrievals of ocean surface temperatures to be repetitively and ...

Abstract: The thermal structure of the troposphere and lower stratosphere during the movement eastward of several Pacific troughs is examined primarily from the standpoint of the distribution of baroclinity within a vertical plane ...

Abstract: Errors in operational forecasts produced by high-speed electronic computers can be classed broadly into two categories: (1) those resulting from inadequacies of the dynamic model, and (2) those resulting from poor specification ...
