..., with emphasis on facilitating runoff and evaporation. Evaporation is an important mechanism for moisture egress, and the larger the area of the evaporative surface, the more efficient the removal of moisture. As joints between individual stone blocks function as micro-scale storm sewers, sealing open joints...

... and is based on effluent removal through surface evaporation with some contribution from plant transpiration. It is possible to reduce the size of a septic tank drain field, for a given effluent flow rate, by combining the two disposal methods. The amount of reduction is proportional to the absorbic capacity...

... This paper describes a laboratory test system in which droplet evaporation data are generated from experiments conducted entirely within a controlled environment chamber. Validation of the test system using deionized water is described. Observed results of evaporation as a function of time...

This paper describes the occurrence and impact of these errors...

... In this paper we report the results of a series of laboratory experiments that were designed to quantify the effects of adding an anti-evaporant to a permethrin formulation. Assessments were made of the effects of the anti-evaporant upon: droplet evaporation rates, droplet retention and bounce...

After temperature stabilization, the specimen was removed from the conditioning medium while the temperatures were recorded four times per second from all thermocouples using a data acquisition system and a computer. The results show that evaporative cooling causes significant changes...

... Previously, we reported a comparison of damage resistance of various coating materials deposited by vacuum evaporation and measured at 2.7 and 3.8 μm. It was found that Si films fail by a thermal process and, in agreement with other studies, that high-index materials, such as Si, tend to have...
