Fractional List Packing for Layered Graphs

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT The fractional list packing number χ ℓ • ( G ) ${\chi }_{\ell }^{\bullet }(G)$ of a graph G $G$ is a graph invariant that has recently arisen from the study of disjoint list‐colourings. It measures how large the lists of a list‐assignment L : V ( G ) → 2 N $L:V(G)\to {2}^{{\mathbb{N}}}$ need to be to ensure the existence of a “perfectly ...

Stable Cuts, NAC‐Colourings and Flexible Realisations of Graphs

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT A (2‐dimensional) realisation of a graph G $G$ is a pair ( G , p ) $(G,p)$, where p $p$ maps the vertices of G $G$ to R 2 ${{\mathbb{R}}}^{2}$. A realisation is flexible if it can be continuously deformed while keeping the edge lengths fixed, and rigid otherwise.

Shear fracture properties of green-glued polyurethane wood adhesive bonds

open access: yes, 2005
The shear fracture properties of green-glued polyurethane wood adhesive bonds subjected to kiln drying were investigated. The local shear strength and fracture energy of the wood adhesive bonds were determined from experimentally recorded complete shear ...

Decoupling climate and human impacts on the nitrogen cycle during the Irish Bronze Age

open access: yesJournal 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.

Effect of saline irrigation on Tetragonia tetragonioides (Pall.) Kuntze grown on different soil types under greenhouse conditions

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Climate change and population growth are major challenges for sustainable food production, particularly in regions affected by water scarcity and soil salinization. In this context, halophytes represent promising candidates as alternative and sustainable food crops for salt‐affected areas.

Reclaimed Well Sites on Salt Affected Soils: Electrical Conductivity and Sodium Adsorption Ratio as Plant Community Response Indicators

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Salt affected soils are common worldwide, resulting from natural causes and anthropogenic activities. Saline and sodic soils often occur in association with oil and gas production, impacting soil properties which can impede vegetation growth and development.
