Numerical simulation for regular drainage in peat soil

Drainage of Peat and Muck Lands Drainage of Peat and Much Lands

Peat and muck soils have unique biological, physical, and chemical properties, and on them the common drainage and management practices that are used on mineral soils are not suitable. Biologically the organic soils support hosts of micro-organisms, mostly bacteria, which are largely responsible for the formation and alteration of the peat. The action of the anaerobic micro-organisms builds up ...

Numerical Simulation of Transport and Diffusion in Drainage Media

In this thesis we develop the numerical tools to simulate heat diffusion in a tissue domain (liver) with a pair of blood vessel trees, coupled with heat advection through these vessels. This problem arises as part of the simulation of radio-frequency ablation of tumors. We develop our methods for a two-dimensional geometry to keep testing and visualization simple while being able to focus on th...

Numerical simulation of unsaturated soil behaviour

The mechanical behaviour of unsaturated soils is one of the challenging topics in the field of geotechnical engineering. The use of finite element technique is considered as a promising method to solve settlement and heave problems, as associated with unsaturated soil. Nevertheless, the success of the numerical analysis is strongly dependent on constitutive model being used. The well-known Barc...

Metatranscriptomic analysis of arctic peat soil microbiota.

Recent advances in meta-omics and particularly metatranscriptomic approaches have enabled detailed studies of the structure and function of microbial communities in many ecosystems. Molecular analyses of peat soils, ecosystems important to the global carbon balance, are still challenging due to the presence of coextracted substances that inhibit enzymes used in downstream applications. We sampl...
