Long-term forest soil monitoring and research often requires a comparison of laboratory data generated at different times and in different laboratories. Quantifying the uncertainty associated with these analyses is necessary to assess temporal changes in soil properties. Forest soil chemical properties, and methods to measure these properties, often differ from agronomic and horticultural soils. Soil proficiency programs do not generally include forest soil samples that are highly acidic, high in extractable Al, low in extractable Ca and often high in carbon. To determine the uncertainty associated with specific analytical methods for forest soils, we collected and distributed samples from two …

Stress-Strain Behavior By Image Analysis, Mix Density And Pre-Strain Effects Of Eps Geofoam, Chen Liu
Theses - ALL
In order to have a deeper understanding of the engineering performances of EPS geofoam, it is necessary to study the stress-strain response and internal strain distribution when loaded. In this investigation, the key objective is to study the stress-strain behavior of EPS geofoam under different conditions and develop construction practical suggestions when using geofoam. The scope of this research is divided into three main sections: (1) study the effect of induced anisotropy on the stress-strain behavior of EPS geofoam; (2) evaluate stress distribution within EPS blocks by using image analysis system; (3) analyze the effect of combining different EPS densities …
