Expansivity of Neogene clays and glacial tills from central Poland [PDF]
, 2014 The revision of classification methodologies for determination of soil expansivity revealed that parameters most frequently used for this purpose are: the liquid limit, plasticity index and swelling parameters which also predominate in older systems of ...

Anisotropy and cyclic loading characteristics of a stiff Bolders Bank glacial till at Cowden [PDF]
E3S Web of ConferencesGlacial tills are widespread across the world, common in northern Europe and found under the North and Baltic Seas. Their geological and geotechnical characterisation is important to the geotechnical design of a wide range of onshore and offshore ...

Scottish late-glacial moraines: debris supply, genesis and significance [PDF]
, 2012 A variety of moraine forms were deposited by glaciers during the Loch Lomond Stadial. Study of such moraines and related landforms provides a valuable source of data on patterns of landscape evolution and climatic change. This thesis presents detailed

An evaluation of strain softening of glacial tills as a result of pore pressure dynamics. [PDF]
, 2013 Deep-seated progressive failures of cuttings in heavily overconsolidated clays have been observed in the field and are well documented, especially for London Clays (Potts, Kovacevic, & Vaughan, 1997; Smethurst, Powrie, & Clarke, 2006; Take, 2003),

Sediment behavior controls equilibrium width of subglacial channels
Journal of Glaciology, 2017 Flow-frictional resistance at the base of glaciers and ice sheets is strongly linked to subglacial water pressure. Understanding the physical mechanisms that govern meltwater fluxes in subglacial channels is hence critical for constraining variations in ...

Rab1A Promotes Hepatic Steatosis by Suppressing Mitophagy via the Raf‐1/ERK1/2/PINK1 Signaling Axis
Advanced Science, EarlyView.Why does fat accumulate in the liver? Our study reveals Rab1A as the molecular switch that silences the cell's mitochondrial cleanup crew. Turning Rab1A off reactivates mitophagy, clears excess fat, and reverses fatty liver disease in mice—offering a promising new therapeutic target for MASLD, a growing global health challenge.

Advanced Science, EarlyView.A rare de novo IFT122‐A773E variant is identified in idiopathic pediatric uveitis and shown to exacerbate retinal inflammation and barrier dysfunction. Mechanistically, the variant enhances IFT43 interaction, elevates calcium signaling, and activates the MEK/ERK/FRA1 axis, revealing a previously unrecognized cilia‐associated pathway that may increase ...
