An Introduction to the Rock Art of Khaybar
Arabian Archaeology and Epigraphy, EarlyView.ABSTRACT Between 2020 and 2024, the Khaybar Longue Durée Archaeological Project recorded 2333 rock art panels around the oasis of Khaybar in northwest Arabia. This dataset documents changing visual expression in a previously under‐researched region. The rock art broadly follows chronological and stylistic patterns observed elsewhere in northern Arabia.

International Journal for Simulation and Multidisciplinary Design Optimization, 2019 The machining industries always eye on increasing hardness and reducing the friction at the cutting tool–workpiece interface to reduce flank wear, thereby enhancing the tool life. The present study investigates the effect of deep cryogenic treatment (DCT)

Determination of absolute tool wear by γ-γ coincidence counting of radiotracers
γ-γ coincidence methods have been applied to obtain absolute flank and crater wear volumes from irradiated high speed steel (HSS) tools using 60Co as the radiotracer. Consistent absolute results can be obtained irrespective of the exact counting geometry
