2. Heterogeneities in samples of contaminated soil
Abstract : Many factors are important during sampling of contaminated soil. One of these is the sample sizes used. By estimation of the Heterogeneity Invariant (HI) it is possible to balance the sample size to one uncertainty contribution that is attached to sampling and sample handling. This is called the Fundamental error. READ MORE

3. Stainless steels fabricated by laser melting : Scaled-down structural hierarchies and microstructural heterogeneities
Abstract : Additive manufacturing is revolutionizing the way of production and use of materials. The clear tendency for shifting from mass production to individual production of net-shape components has encouraged using selective laser melting (SLM) or electron beam melting (EBM). READ MORE

4. Modeling of dose and sensitivity heterogeneities in radiation therapy
Abstract : The increased interest in the use of light ion therapy is due to the high dose conformity to the target and the dense energy deposition along the tracks resulting in increased relative biological effectiveness compared to conventional radiation therapy. In spite of the good clinical experience, fundamental research on the characteristics of the ion beams is still needed in order to be able to fully explore their use. READ MORE

5. Solute transport through fractured rocks : the influence of geological heterogeneities and stagnant water zones
Abstract : To describe reactive solute transport and retardation through fractured rocks, three models are developed in the study with different focuses on the physical processes involved and different simplifications of the basic building block of the heterogeneous rock domain. The first model evaluates the effects of the heterogeneity of the rock matrix and the stagnant water zones in part of the fracture plane. READ MORE
