Soil conditions required for reaction wood formation of drunken trees in a continuous permafrost region

open access: yesArctic, Antarctic, and Alpine Research, 2020
Black spruce trees lean to form “drunken” forest on degrading permafrost; however, the causes of tree leaning on continuous permafrost remain unclear. Leaning events are recorded by reaction wood formation in tree rings, and it remains unclear what soil ...

PROPERTIES OF CHARCOAL PRODUCED FROM REACTION WOOD IN TREES INCLINED DUE TO WIND1

open access: yesRevista Árvore, 2017
Inclined trees produce reaction wood, whose properties are distinct from normal wood. This situation can affect the production of charcoal. This study was conducted to evaluate the quality of charcoal derived from reaction wood in trees of a commercial ...

Influence of Pre-Impregnation Acetic Anhydride and Heating Time on Mechanical and Physical Properties of Wood-Plastic Composites

open access: yesDrvna Industrija, 2023
This research aimed to assess the influence of different pre-impregnation times (PITs) (60, 180, and 300 min), heating or reaction times (H/RTs) (60, 90, and 120 min), and chemical modification of wood flour (WF) on the mechanical and physical properties

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

open access: yesFEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral
