Flow injection with an integrated retention/photometric detection unit for the determination of iron in water
(ACADEMIC PRESS INC JNL-COMP SUBSCRIPTIONS, 1996-05)
An integrated retention/photometric detection method for the determination of microamounts of iron was developed. The method is based on the retention of the reaction product of the analyte with ferrozine in a flow cell ...

Effects of Biological Stabilization on the Water Retention Properties of Unsaturated Soils
(Asce-amer Soc Civil Engineers, 2019-07-01)
The soil water retention curve (SWRC) is one of the most fundamental characteristics of unsaturated soils. Because unsaturated soils are subjected to a range of natural processes and engineered treatments, a thorough ...
Impact of land use changes on the hydrological properties of volcanic ash soils in South Ecuador
(2002-06)
The effect of land use on the water retention capacity of Umbric Andosols in south Ecuador was studied. The objective was to acquire a better insight into the hydrological processes of the ecosystem and the role of the ...
Simple functions for describing soil water retention and the unsaturated hydraulic conductivity from saturation to complete dryness
(2020-09-01)
Many applications require accurate soil hydraulic functions that can describe the dynamics of water in variably saturated systems from full saturation to complete dryness. Current functions considering zero water content ...
