Peter Hammerschmidt,Kirsten Anerations can be concluded that epoxy resin mortars which are penetrated by chemicals (HCl; NaOH) show a low durability of the adhesion between epoxy resin and quartz and therefore they change their properties very rapidly.

Stephan Maykusers, such as glass and graphite. Among the many reasons for this interest is the possibility of fabricating materials for use as primary and secondary structures that, on the basis of weight, are stronger and more rigid than conventional materials of construction.

Albrecht Rohrmann,Johannes Schädlerhow it is made and the effects of process variables, including the resultant chemistry, on the initial properties.* Then, knowing (or presuming) the component properties and attributes, one may try to calculate the properties of any given composite structure made from these and at the same time esti

Björn Egner,Dieter Rinkd have properties superior to the components considered separately. The layered systems made of cement composites and that are used in construction typically consist of an overlay with a constant or variable thickness, usually made of cement mortar and a substrate, for which mainly concrete is used

Matthias Wohltmann events between these two types of cells that promote the passage of the leukocyte out of the blood vessel. In the past few years, there has been a dramatic increase in our understanding of this complex process, with multiple new receptor interactions being identified and activation induced changes
