New Results From the Pre‐Pottery Neolithic Site of Al Uyaynah, Tabuk, in Northwestern Saudi Arabia
ABSTRACT Al Uyaynah is a low sandstone mound on an alluvial plain, long known for its extensive surface remains of stone‐built circular and rectangular structures. Following test excavations in 2012, more detailed excavation was undertaken in 2016 within one of the largest rectangular stone structures.

Much of this literature looks at such supply‐chain disentanglement from the viewpoint of corporate and formal regulatory practices ...

ABSTRACT Background There is compelling evidence that treating high‐grade squamous intraepithelial lesions (HSIL), the anal squamous cell cancer (ASCC) precursor, reduces the risk of developing ASCC. Using high‐resolution anoscopy (HRA), surgical excision, ablative and topical therapies are widely used to treat HSIL.

ABSTRACT Ten timbers from the spire scaffold of Salisbury Cathedral were dated using a combination of ring‐width dendrochronology, stable oxygen isotopic dendrochronology and radiocarbon dating. Seven timbers were coeval and assigned a combined empirical felling date range of 1352–1378, which was further refined to 1351–1359 (OxCal 95.4%).

Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...
