Abstract: A method of improving the evaporation from surface bodies of water which comprises artificially inducing air flow over a body of water using air jets at an air flow rate of at least 10 m/second while the water partial pressure of air at the surface temperature of the body of water (Pbs) is greater than the water partial pressure of the ambient air at the surface temperature of the body of water (Pas). The rate of evaporation can be materially enhanced by the transfer of geothermal heat from the lower region of the body of water to the surface region by means of a heat exchanger or a heat pipe.

Abstract: A method for determining virtually a set of design allowables for a composite material is disclosed. The method includes receiving information about the composite material and a given set of architectures, available test data of the composite material, and a test matrix identifying desired tests to be performed virtually on the composite material and different set of architectures.

Finite element models of relevant test specimens are generated according to the test matrix and integrating the micromechanical material properties, and are analyzed. A set of allowables and associated properties is generated based on the finite element analyses results.

Abstract: A multi-purpose bed liner and deck topper includes a shell that may be connected to a vehicle cargo bed. The shell is movable between a bed liner position and an inverted deck topper position. The shell includes a shell base and shell sidewalls extending from the shell base.
