Surface mobility using wheeled mobile robots (Rovers) is one of the important technologies for lunar/planetary exploration missions. The rover in these missions significantly expands the exploration area and thus increases the scientific or programmatic return from the mission. These planetary exploration rovers are expected to travel long distances and perform complex tasks in order to fulfill...
Cadmium (Cd) concentration in soil solution and its bioavailability is controlled by sorption-desorption reactions. The objective of this research was to compare Cd adsorption behavior in six calcareous and four acid soils. Soil samples were equilibrated with 0.01 M Ca(NO3)2 containing 25 to 3200 mg Cd L−1. Results showed that the tendency for adsorption was high at low Cd concentrations (0-400...
We collected and analyzed breakthrough curve (BTC) data to identify the parameters controlling transport from a series of undisturbed fully saturated soil cores and a field test at the Shale Hills Critical Zone Observatory in central Pennsylvania. The soil cores were collected in a continuous hole extending across the soil profile vertically at one location to quantify how solute transport beha...
