Near Surface Geophysics, EarlyView.Abstract Electrical resistivity tomography (ERT) has been shown to be effective for surveying and monitoring dams, due to the method's sensitivity to moisture content and relevant physical properties (e.g., porosity). Automated ERT systems, capable of time‐lapse monitoring, can be used to detect variations in ground conditions.

Soil reaction to heavily loaded rubber tracks and tyres [PDF]
, 2007 The importance of undercarriage design with respect to its effect on soil density changes grows with the size of harvest machinery. Therefore this study elucidates the mechanics of soil displacement caused by different undercarriage systems of combine ...

Polymer International, EarlyView.The 100% recycling of optimal polycarbonate/acrylonitrile–butadiene–styrene/poly(methyl methacrylate) (PC/ABS/PMMA) blends, identified through the mixture design, over multiple successive cycles provides valuable insights into their life cycle. Subsequently, chemical, rheological, thermal and mechanical characterizations will be carried out to evaluate

Permafrost and Periglacial Processes, EarlyView.ABSTRACT Under continued climate warming, understanding present‐day permafrost distribution and the controls on ground thaw are critical for predicting permafrost thaw trajectories and associated implications. This study presents a high‐resolution investigation of permafrost extent and active layer thickness (ALT) across a coniferous forested hillslope

Unsaturated soil mechanics for slope stabilization
, 2011 Rainfall-induced slope failures commonly occur in the unsaturated zone above groundwater table in many steep residual soil slopes. Dynamic variations in groundwater table and flux boundary conditions across ground surface result in changes in pore-water ...

A modification of the mixed form of Richards equation and its application in vertically inhomogeneous soils [PDF]
, 2011 Recently, new soil data maps were developed, which include vertical soil properties like soil type. Implementing those into a multilayer Soil-Vegetation-Atmosphere-Transfer (SVAT) scheme, discontinuities in the water content occur at the interface ...

Modelling the Thermo-plasticity of Unsaturated Soils
, 2013 This paper presents a highly-coupled thermo-plasticity model for unsaturated soils. The effect of temperature on the mechanics of unsaturated soils is briefly addressed. Then the equations of the developed model, so-called ACMEG-TS, are detailed. Finally, the model is validated by the means of comparisons with experiments.

Pest Management Science, EarlyView.SYN‐A, a naturally derived synergist, inhibited key metabolic pathways associated with pyrethroid insecticide resistance in cabbage stem flea beetle (CSFB) and its parasitoid Microctonus brassicae. SYN‐A restored pyrethroid efficacy against resistant CSFB allowing up to 80% reduction in application rates.
