Matemathics Model Analysis of Biomechanical Behaviour of Three Dental Materials to Loading Related to Bruxism
The aim of study is to highlights the biomechanical behaviour of three dental materials during loading related to bruxism. It was created a finite element model of mandibular canin. The modelling was performed in Rhinoceros, AutoCad and the finite element analysis was performed in COSMOSWorks 2010. Occlusal loading was applied vertical and had a value of 1000N. The analysed cervical restorations were performed by dental amalgam, composite resins and glassionomer cements. The results confirm clinical observations related to the correlations between maximal occlusal forces to incisal margin of canin and maximal tensions to the level of cervical restorations

Investigating phase behavior and structural changes in NiO Ni YSZ composite with monochromatic in situ 2D and static 3D neutron imaging
Non-destructive characterisation of dopant spatial distribution in cuprate superconductors
Proper characterisation of investigated samples is vital when studying
superconductivity as impurities and doping inhomogeneities can affect the
physical properties of the measured system. We present a method where a
polarised neutron imaging setup utilises the precession of spin-polarised
neutrons in the presence of a trapped field in the superconducting sample to
spatially map out the critical temperature for the phase transition between
superconducting and non-superconducting states. We demonstrate this method on a
superconducting crystal of the prototypical high-temperature superconductor
(La,Sr)CuO. The results, which are backed up by complementary magnetic
susceptibility measurements, show that the method is able to resolve minor
variations in the transition temperature across the length of the LSCO crystal,
caused by inhomogeneities in strontium doping.Comment: 11 pages, 7 figure
