Mesenchymal stem cells (MSCs) have the potential to differentiate to other cells and this feature makes it as an attractive source in tissue engineering. Mesenchymal stem cells are subjected to many mechanical stimuli in vivo such as an in vivo pressure loading and one of the cell respond to these stimuli is differentiation to cartilage or bone cell. One of the most significant ways for this goal...
Currently, very few experimental results describing the behavior of subcables under transverse load are available. Those results are of importance for predicting how a full-sized cable-in-conduit conductor behaves during operations. Current experimental devices used to study the effect of transverse load on the electrical performance of cables utilize concave plates to apply...

The handling of photovoltaic cells is getting a growing concern. Due to the significant fraction of the material costs on the overall costs of solar wafers the cell thickness was reduced from initially 300 μm down to 200 μm or even 150 μm. At the same time, the size of typical cells remained at 156 × 156 mm2. Thus, solar cells have the same thickness like microelectronic chips but their size is about...
Delamination between copper and epoxy molding compound (EMC) is one of the common failure modes in packages due to relatively weak adhesion at the interface. Delamination is difficult to predict because a package is often with a complex structure design constructed with different materials and under combined normal and shear loading. Development of cohesive zone elements applied in FEM has emerged...
