Evaluation of Spiro Orthocarbonate Monomers Capable of Polymerization with Expansion as Ingredients in Dental Composite Materials characterized by an expansion in volume. While potential applications for these unique monomers are quite extensive, the topic of dental restorative resins is one area of polymeric biomaterials, in which the need for materials with reduced polymerization shrinkage is well established. An efficient

,Was die Bankangestellten „sind“,and the change in the characteristics of X60 steel over time as a result of its degradation. It is shown that the turbulence of the oil flow and the shocks significantly reduce the residual life of the pipeline. The degradation of its material (X60 steel) over time puts the value of this resource in
