With the increasing insight into the connections and governing laws it soon became obvious, however, that such a clear separation could be regarded as more or less obsolete; within almost any field of chemic

Electron microscopy has provided many new characters that have initiated phylogenetic discussions about the relationships among the “golden algae”. Consequently, new taxa have been described or old ones revised

Classification of Structural Sandwich Panel Behaviourn the relative stiffnesses of the face and core materials. The number of combinations possible, and the complexity of the equations that sometimes emerge from analyses of sandwich behaviour, can make it difficult for the designer to decide which aspects of sandwich behaviour are important, and which

The Development of Sandwich Structures for Naval Vessels During 25 Years of the FRPsandwich technique started in the late-60’s in close co-operation between Karlskronavarvet (KKRV), Royal Institute of Technology (KTH) and the Swedish Defence Materials Administration (FMV). An extensive research and development work has been performed since then to increase the structura
