The provision of seamless public transport supply requires a complete understanding of the real traffic dynamics, comprising origin-to-destination multimodal mobility patterns along the transport network. However, most current solutions are centred on th
Preliminary in vitro tests with pre-osteoblast cell line show good cell-material interaction on the matrices prepared in the presence of Mg. To the best of our knowledge this work represents the first attempt to mineralize recombinant collagen type I derived protein proving the simultaneous effect ...
The influence of that transformation on the Young moduli and T• of formed polymers is considered. This is exemplified by the epoxy cure process. Another aspect is the mechanism of plastic deformation of polymeric glasses and the third one is the isothermal enthalpy and volume relaxations in ...
PC-CT, on the other hand, is non-destructive, 3D and fully quantitative. Importantly, not only do we demonstrate achievement of high image quality at two different synchrotron facilities, but also with commercial x-ray equipment, which makes the method available to any research laboratory. The ...
While we could have obtained an optimal error term with the same proof idea, the weaker bound is sufficient for our analysis and we use it for simplicity. Recall that the flat pieces of the contours \gamma _1 and \gamma _2 from Fig. 3 lie on the lower and upper half plane, ...
(PLGA) using a high pressure gas that avoids the use of organic solvents and high temperatures. However, the technique typically yields a closed pore structure, which is disadvantageous in many applications of cell transplantation. In addition, a solid skin of polymer results on the exterior ...
