Journal of Quaternary Science, EarlyView.ABSTRACT This paper examines regional and chronological variations in Acheulean handaxe morphology during Marine Isotope Stage 11 (c. 425–365 ka BP) in Britain. Using a data set of 737 handaxes from 13 securely dated sites in East Anglia and the Thames Valley, we apply three‐dimensional geometric morphometric analysis to examine morphological ...

Controlled Irradiative Formation of Penitentes
, 2006 Spike-shaped structures are produced by light-driven ablation in very different contexts. Penitentes 1-4 m high are common on Andean glaciers, where their formation changes glacier dynamics and hydrology.

Decoupling climate and human impacts on the nitrogen cycle during the Irish Bronze Age
Journal of Quaternary Science, EarlyView.ABSTRACT Disentangling climate variability and human activity in past nitrogen cycling is key to understanding ecosystems. Previous studies in Ireland observed a widespread, permanent shift in terrestrial nitrogen cycling during Later Prehistory, potentially linked to intensifying land‐use.

Journal of Quaternary Science, EarlyView.ABSTRACT During the last glacial period, the Laurentide Ice Sheet (LIS) was the largest terrestrial ice sheet on Earth. Its evolution since the Last Glacial Maximum profoundly influenced Earth's geodynamics and surface processes. Investigating the past dynamics of the LIS provides critical insights into how contemporary ice sheets may respond to ...

Journal of the Science of Food and Agriculture, EarlyView.Abstract BACKGROUND Assessing crop's responses to elevated carbon dioxide (eCO2) is crucial for global food security. This study examines the impact of eCO2 (700 μmol mol−1) on the cultivars of lentil (Lens culinaris), local Pardina Verde Rayada lentil (PVRL), and commercial Pardina lentil (PL) in terms of the productivity and nutritional composition ...

Photooxidation of 18‐Carbon Polyunsaturated Fatty Acids to Prepare Mono‐Hydroxylated Octadecanoids
Lipids, EarlyView.We developed a fast and simple one‐step synthetic strategy to produce mono‐hydroxylated metabolites based on the photosensitized oxidation of 18‐carbon polyunsaturated fatty acids (PUFAs). This approach could likely be extended to other PUFAs, suggesting that photosensitized oxidation could be employed to rapidly prepare hydroperoxides from multiple ...

Hydrographic measurements in Jökulsárlón lagoon, Iceland [PDF]
, 2013 Jökulsárlón lagoon is an enclosed lake bordering the retreating Breidamerkurjökull glacier which flows down from the Vatnajökull ice cap. As the glacier calves most of the ice it releases decays within the lake and the addition of the stored fresh water ...
