Productivity of boreal forests in relation to climate and vegetation zones

, 2005
Many properties of forest stands in the boreal main zone have means that are specific to each boreal zone (i.e. subzones of the main climatic zone). These properties are arranged in zonal systems, called forest vegetational zones.

Sheath‐to‐Artery Diameter Ratio: A Robust Predictor of Early Access‐Site Adverse Events in Percutaneous Procedures

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Vascular access site complications (VASCs) remain an important source of morbidity following percutaneous interventions. Although the sheath‐to‐femoral artery ratio is a recognized risk factor in transcatheter aortic valve implantation (TAVI), its role across a broader range of femoral procedures is less well defined.

Challenges of Bio‐Syngas Conversion to High‐Value‐Added Liquid Chemicals and Fuels via COx Hydrogenation

Carbon Energy, EarlyView.
Converting biomass‐derived syngas into value‐added fuels and chemicals offers a promising route toward carbon neutrality, yet unfavorable H2/COx ratios, elevated CO2 levels, and trace impurities pose persistent obstacles. This review examines strategies spanning syngas conditioning, impurity‐tolerant catalyst development, and integrated process design,

Management Challenges for Multiple-Species Boreal Forests [PDF]

Recent research in natural sciences shows that boreal forests' dynamics are much more complex than what many models traditionally used in forestry economics reflect. This essay analyses some challenges of accounting for such complexity.

Warmer Sphagnum moss, less soil carbon loss : Anaerobic respiration and temperature response along a boreal forest-peatland ecotone [PDF]

Climate warming is predicted to rapidly change the local environmental conditions in peatland systems at high latitudes. This study explored soil respiration rates with microbial community compositions along a transect from well-drained upland forest to ...

Atom Swapping Reaction on Diborylcarbenoid: Synthesis and Electronic Structure of Inorganic Chalcogenophene Analogues

Chemistry – A European Journal, EarlyView.
ABSTRACT Inorganic analogues of aromatic compounds, wherein C═C bonds are replaced with B─N bonds, are isoelectronic with the original aromatic compounds, however, they can show different properties. While borazine, an inorganic analogue of benzene, has been well‐studied, inorganic analogues of chalcogenophene have been less explored.

Carbon emission assessment of tunnel infrastructures: From construction to operation

Deep Underground Science and Engineering, EarlyView.
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...
