CULTURAL FUSION IN LATE BRONZE AGE GOLDWORK: DIADEMS AND MOUTH‐PIECES FROM HALA SULTAN TEKKE, CYPRUS
Summary This study investigates recently discovered gold diadems and mouth‐pieces from seven chamber tombs and one shaft tomb at the Late Bronze Age cemetery of Hala Sultan Tekke, dating from the fifteenth to the thirteenth centuries BC. The chamber tombs, all containing multi‐generational burials, yielded a variety of ornaments, which are analysed in ...

Testing the Strength of Buried Surface Hoar Weak Layers Under Combined Compression and Shear Loading
Abstract We experimentally determined the multiaxial strength of weak layers of buried surface hoar using displacement‐controlled tests under combined normal and shear loading on a custom testing machine. We tested 63 samples from three different weak layers, with strengths ranging from 1 to 10 kPa with considerable scattering. While shear strength was
