Torque required to twist and cut loose Scots pine stumps [PDF]
, 2012 Stump wood is a possible source of renewable energy, but before its potential as a fuel can be utilised to a high degree, new harvesting techniques should be developed to reduce the environmental impact (notably ground disturbance) of harvesting stumps ...

Advanced Materials, EarlyView.A Nb‐proximitized Josephson junction based on a WTe2/α‐Fe2O3 heterostructure exhibits a robust superconducting diode effect with programmable polarity. The diode direction can be trained by magnetic fields and switched by temperature cycling, revealing tunable finite‐momentum pairing states and competing superconducting states in symmetry‐broken ...

Beech shearing/high-stumping to control understory interference
The Forestry Chronicle, 2017 The research evaluated opportunities for cutting off small understory beech root suckers at 0.6-0.9 m above ground. By six years (pilot test) after cutting with lopping shears in a closed-canopy uneven-aged northern hardwood stand, 91% of high stumps ...

Advanced Materials, EarlyView.Molecular doping of conjugated polymers is fundamentally constrained by thermodynamic phase behavior. This Perspective reframes doping efficiency and stability in terms of miscibility limits, binodals, and solvus boundaries, highlighting the role of effective interaction parameters and charge transfer.

Spruce regeneration on woody microsites in a subalpine forest in the western Carpathians
Silva Fennica, 2015 The density of [L.] Karst. regeneration on different microsites, the quantity and quality of woody microsites, and seedling occurrence probability on stumps and fallen deadwood were studied in a subalpine forest that has been under protection for ...

) stumps on their colonisation by insects in the mountains
, 2019 Tree stumps provide habitat for insect assemblages, which are influenced by various factors. Among these factors, physical and chemical changes of the stumps, fungi developing in the dead wood and stump size are most often reported.
