Psoriasis is a chronic inflammatory skin disease characterised by immune cytokine stimulated epidermal hyperproliferation. Previous modelling studies of psoriatic have been limited to 2D models and lacked cell-cell interactions. We developed the first 3D agent-based model cell dynamics gain insights into complex spatio-temporal changes, in particular how stimuli induces hyperproliferation alter...

production of fe-c alloy powders by mechanical alloying was studied. fe and graphite elemental powdermixtures containing 0.8 and 1.5wt.% graphite were mechanically alloyed using a planetary ball mill. thestructural changes of powder particles during mechanical alloying were studied by x-ray diffractometery,scanning electron microscopy and microhardness measurements. for both compositions, mecha...
