Improved Microscopical Settling Tube

A Combined Raindrop Aggregate Destruction Test-Settling Tube (RADT-ST) Approach to Identify the Settling Velocity

The use of sediment settling velocity based on mineral grain size distribution in erosion models ignores the effects of aggregation on settling velocity. The alternative approach, wet-sieved aggregate size distribution, on the other hand, cannot represent all destructive processes that eroded soils may experience under impacting raindrops. Therefore, without considering raindrop impact, both me...

A vacuum tube based improved solar cooker

A new type of improved solar cooker based upon the use of a single vacuum tube is presented in this paper. The proposed cooker utilizes a solar collector consisting of parallel plane rectangular glass mirror strips mounted inside a wooden frame and requiring one dimensional solar tracking through a common driver. The proposed design can be either installed over the roof top of a house or near a...

Direct Readout of Sediment Analyses by Settling Tube for Computer Processing.

Sediment fall-velocities measured by the Woods Hole Rapid Sediment Analyzer can now be obtained directly on punched paper tape in a form suitable for processing by a computer. This technique saves much time because it eliminates manual card punching, a step in which an operator transfers values from sediment analyses to punch cards in order to make the data acceptable tocomputers.
