Particle analyzers utilize particle 'focusing' by establishing high particle concentrations within a thin stream of gas. Most specimens for analysis, like gunpowder residue in ambient air, do not show these properties. Aerodynamic lens arrays which consist of many tubes which reshape the particle fl.....

A subchondral defect is usually characterized by a structural breakdown of the articular cartilage and the bone underneath due to trauma or disease, leading to chronic disabilities. Treating such defects is an important medical target since in the adult patient, damaged cartilage cannot spontaneousl.....

Infra-red (IR) imaging (in the LWIR and MWIR bands) is widely used for observation and surveillance applications. Most of IR optical materials are very sensitive to temperature changes. This sensitivity is reflected in a temperature dependent refractive index, that in turn it affects the focal lengt.....

Highlights:p53, the most important tumour suppressor protein in the cell, is a homotetrameric protein that has a pivotal role in the cellular anti cancer defense mechanism.p53 is active as a tetramer: the tetramer binds DNA much tighter than the monomer / dimer and is retained in the nucleus while t.....
