Coupled 3-D full-Stokes modelling of tidewater glaciers
Annals of Glaciology, 2022 Tidewater glaciers are an important and difficult part of the cryosphere to study owing to their complex nature and often inaccessible and physically challenging environments. The interaction of glacier and fjord processes furthermore presents particular

Journal of the American Chemical Society, 1996 A simple method to prepare porphyrin 'wheels' on a micrometer scale is described. It is possible to arrange several types of porphyrin derivatives, including Protoporphyrin IX and Chlorophyll-a, in the form of rings using this method. A mechanism for the formation of these types of assemblies is proposed that is based on the generation of '2D-gas ...

Soil Compaction Effects on Root-Zone Hydrology and Vegetation in Boreal Forest Clearcuts [PDF]
, 2019 Soil compaction is a common consequence of forestry traffic traversing unprotected, moist soils; it decreases porosity and affects hydraulic conductivity even in coarse-textured soils. The aim here was to study root-zone hydrology and vegetation in three

A control volume based formulation of the discrete Kirchoff triangular thin plate bending element [PDF]
, 2009 A control volume method is presented for predicting the displacement and rotation of thin transversely loaded flat plates. The new procedure uses discrete Kirchoff triangle (DKT) elements but introduces a dual mesh of interconnected control volumes (CVs)

Shape optimisation of rim structure of aluminium alloy car wheels based on 90° impact test
Scientific ReportsAutomotive wheels are critical components for vehicular safety, with the rim subjected primarily to radial bending loads during operation. Balancing rim thickness and structural integrity under these loading conditions is imperative.
