Suction tests on sliding soil in interface landslide based on filter paper method
Suction is a decisive factor to control the state of unsaturated soils. The filter paper method is an indirect method for measuring suction, which has the advantages of low cost, large measuring range and high precision.

A rapid method for determining the soil-water characteristic curves in the full suction range
The traditional methods for determining the soil-water characteristic curve (SWCC) in the full suction range always takes several months. To better guide the engineering practice with the theory of unsaturated soil mechanics, the rapid determination of ...

Performance of Three Enzymic Methods for Filter Paper Glucose Determination [PDF]
Collection of blood spots on filter paper offers a practical alternative for home monitoring of diabetic patients. We have compared the merits of three protein precipitants, trichloracetic acid (TCA), perchloric acid (PCA) and sulphosalicylic acid (SSA) for the elution of glucose from the filter paper, and their subsequent effects on three enzymic ...
