Environmental dynamics and timing of the late Eemian interglacial to the Weichselian pleniglacial at Lichtenberg, Germany: implications for the Oerel and Glinde interstadials

Boreas, EarlyView.
The terrestrial sediment archives of northern Germany provide important insights into Late Pleistocene climate variability, but continuous and well‐dated records remain rare. In particular, the age and stratigraphic position of the Oerel and Glinde interstadials within the Early Weichselian to pleniglacial transition remain poorly constrained.

Evaluation of the Rb/Sr ratio as an indicator of chemical weathering: a case study from five sedimentary sections in Northeast China

Boreas, EarlyView.
Chemical weathering plays a pivotal role in the Earth's surface material cycle and global climate regulation. It not only facilitates the reconstruction of palaeoclimate characteristics but also provides essential insights into Earth's evolutionary history.

Acoustic Emission Characteristic Parameters and Damage Model of Cement-Modified Aeolian Sand Compression Failure

Applied Sciences
Aeolian sand is widely distributed in desert areas, but it has certain challenges in the application of roadbed engineering due to its loose particles and poor stability. Cement-modified aeolian sand has gradually become the mainstream improvement method

Influential Factors in Transportation and Mechanical Properties of Aeolian Sand-Based Cemented Filling Material

Minerals, 2019
Given that normal filling technology generally cannot be used for mining in the western part of China, as it has only a few sources for filling gangue, the feasibility of instead using cemented filling materials with aeolian sand as the aggregate is ...

Geochemical and granulometric fingerprints of 8200 years of westerly wind variability in inner‐fjord lake sediments from Svalbard

Boreas, EarlyView.
The Arctic is warming faster than any other region on Earth. As sea ice diminishes, the surface boundary conditions, such as roughness and air–sea coupling, change and open‐water fetch increases. This may enhance wind forcing on Arctic coasts. Lake sediments can record these changes through the deposition of wind‐blown grains and elements, offering ...

Experimental Study on Fabrication of Environment-Friendly Concrete by Solidifying Aeolian Sand and Natural Gravel with Fly Ash-Based Geopolymer

Buildings
To tackle the shortage of river sand resources and excessive carbon emissions in building materials, environment-friendly concrete can be fabricated by solidifying aeolian sand and natural gravel with a fly ash-based geopolymer.

Spatial variation in morphological traits of natural Haloxylon ammodendron populations on the eastern margin of the Badain Jaran Desert

Plant Biology, EarlyView.
Natural Haloxylon ammodendron populations on the eastern margin of the Badain Jaran Desert showed size‐associated differences in plant height, crown diameter, and spatial patterns among stem‐base diameter classes. These patterns describe morphological spatial variation but do not establish specific environmental drivers.

Simulation of realistic infrared texture of aeolian sand ripples

, 2011
Texture is of vital importance when rendering realistic infrared images. Traditional attempts to simulate infrared textures often suffer from insufficient realism seen in actual infrared images.

Alternative approaches to dryland reclamation enhance vegetation cover and soil stability at a former uranium mine

Restoration Ecology, EarlyView.
Abstract Introduction Conventional reclamation methods to recover dryland ecosystems after mineral extraction often have low success. Alternative reclamation techniques may help overcome the many challenges to establishing persistent native vegetation and stable soils.

Seismic Damage Behavior of Aeolian Sand Concrete Columns with an Inner Square Steel Tube

Advances in Civil Engineering, 2019
In order to promote the application of aeolian sand in steel-concrete composite structures, the aeolian sand concrete columns with an inner square steel tube is proposed in this paper. This kind of column is composed of aeolian sand concrete, reinforcing
