The Late Agricultural Development of Central Arabian Oases—Archaeobotanical and Archaeozoological Studies of the al‐Kharj Oasis

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT While oasis settlements emerged during the Bronze Age in Eastern and Northern Arabia, the settlement process in Central Arabia was different. Excavations at al‐Yamāma—main ancient settlement of the al‐Kharj oasis (Riyadh Province, KSA)—suggest that the latter did not emerge before the second half of the first millennium BCE.

Vegetation dynamics and dominant driving factors in a semi-arid coal mining area under a disturbance–restoration zoning framework

Geocarto International
Understanding vegetation dynamics in arid mining ecosystems remains limited, despite the extensive disturbances imposed by mining activities. Integrating remote sensing and field observations, we applied the Mann–Kendall test, Theil–Sen slope, the ...

The Early Upper Palaeolithic open‐air site of Friedrichsdorf‐Seulberg, Germany, in the context of the northern central European Aurignacian

Boreas, EarlyView.
Our knowledge of the Early Upper Palaeolithic occupation in northern central Europe is very limited, and recent research at the open‐air site of Friedrichsdorf‐Seulberg in Hesse, Germany, provides important new information on the Aurignacian. The site is rather small (26.5 m2) and spatial analysis identified a central hearth with two associated ...

Peak particle velocity for rockbursts in underground coal mines and for shot-hole explosions in open-pit mines

, 2011
The paper presents some results of in-situ seismological observations in hard-coal mines in the Ostrava-Karviná Coal Basin (OKCB) (Czech Republic) and in open-pit brown-coal and shale mines in Northwest and Central Bohemia, respectively.

‘Elbow grease and yellow soap’: Housework time in working‐class households in late‐nineteenth and early twentieth‐century Britain

The Economic History Review, EarlyView.
Abstract Housework is central to feminist calls for recognition of women's work, economic histories explaining the sexual division of labour, and claims regarding the progressive role of scientific knowledge. Yet little is known about the time it actually took. We address this lacuna.
