Analysis of Soil Structure Turnover with Garnet Particles and X-Ray Microtomography
Matter turnover in soil is tightly linked to soil structure which governs the heterogeneous distribution of habitats, reaction sites and pathways in soil. Thereby, the temporal dynamics of soil structure alteration is deemed to be important for essential ecosystem functions of soil but very little is known about it. A major reason for this knowledge gap is the lack of methods to study soil stru...
متن کاملDynamics of soil pore space structure investigated by X-ray microtomography
Transport and transformation processes of solid, liquid and gaseous compounds/components in soils are intimately connected and strongly dependent on the state of soil structure and pore space geometries. Soil structure in turn is inherently dynamic due to changes in pore water pressure resulting in shrinking and swelling and/or soil compaction and shear deformation by applying external loads an...
متن کاملX-Ray Microtomography for Food Quality Analysis
In an effort to understand the physical and rheological behavior as well as the mechanical and sensory attributes of foods, processing focus and emphasis have shifted to the microstructure level. Microstructure elements such as air bubbles or cells, starch granules, protein assemblies and food biopolymer matrices contribute greatly to the identity and quality of foods (Aguilera, 2005). The micr...

First, X-ray computed to...
متن کاملNetwork Analysis of Filter Cake Pore Structure by High Resolution X-Ray Microtomography
Continuous filtration of fine particles involves filter cake formation and removal of surface moisture by drawing air through the pore structure network. Conventional network theory can be use to study the phenomena of flow through a porous structure by treating the pores as discrete volumes and connecting these with pore throats as resistances of zero volume. In this regard, analysis of the po...
