Work-Function Anisotropies As An Origin Of Long-Range Surface Forces, Nancy Burnham, R Colton, H Pollock
Work-Function Anisotropies As An Origin Of Long-Range Surface Forces, Nancy Burnham, R Colton, H Pollock
Nancy A. Burnham
Unusual effects noticed in previous force microscopy data are explained by a model based on work-function anisotropies and their associated patch charges. Measurable forces between macroscopic bodies can be due to the interaction of patch charges, with important consequences in the fields of surface forces, contact mechanics, adhesion, Schottky barriers, and the surface properties of insulators.

Effects Of Hurricane Hugo On Agricultural Structures, Jay D. Harmon, George F. Grandle, Clyde L. Barth
Jay D. Harmon
A tour of damage to agricultural structures by hurricane Hugo was conducted. Empty grain bins which exhibited improper anchorage tended to fail. Post-frame buildings that were improperly anchored, braced or fastened failed, while others that were designed and constructed using sound engineering practices generally withstood hurricane winds.
