An isotopic perspective on the transport of Byzantine mining camp laborers into southwestern Jordan.
Abstract
The Byzantine Empire managed a complex administrative network that controlled the mining and processing of natural resources from within its boundaries. Scholars relying upon archeological and textual evidence debate the level of imperial involvement in these ventures, particularly i...

Abstract
We identified genetic kinship among the individuals. A direct child-parent relationship was detected in one burial, providing the oldest molecular genetic evidence of a nuclear family. Strontium isotope analyses point to different origins for males and children versus females. By this approach, we g...

Abstract
At Elsau near Winterthur (CH), a 9th century AD grave with a female skeleton was found in 2003. This grave was reopened one to six years after burial. After manipulating the partially decayed skeleton, the grave was filled with a layer of rocks and a claw of a sea eagle as well as the paw of a fox w...

Abstract
The metallic radionuclide (86)Y was produced by irradiation of enriched (86)SrCO(3) on a low-energy proton-only cyclotron. Irradiations up to 20 microA for 2h were performed with 11 MeV protons using a water-cooled target mounting with circulating chilled helium. Experimental thick target yields of...
