In 30 trees from two over 100 years old, immission-damaged beech stands in the Hils, Lower Saxonia, the growth increment at breast height (1,30 m) as well as moisture content and wood density were investigated. Trees of damage class 2 with the greatest damage showed greater increment from...

The short-term water resistance of one urea formaldehyde (UF) and two phenol formaldehyde (PF) resins in particleboard of Norway spruce, resin films, and impregnated glass filters are compared. The results indicate that the physical properties of particleboard can be degraded through wood-adhesive...

containing microfibrillated cellulose (LMFC) produced from non-delignified pine and spruce sawdust directly or after lignin-preserving sulfonation, and evaluate their grade by measuring strength properties of self-standing films made from the LMFCs and by determining their ability to reinforce fluting ...
This is not limited to bimetallic catalysts, trimetallic or multimetallic catalysts also possess more outstanding catalytic properties, such as good active stability and selectivity, than monometallic catalysts, but are limited by the fact that their synthesis may be more complex, wordy, and relatively...
We present results from field and pot trials showing that chemical (pH, phosphate availability) and physical (water holding capacity) properties of composted wastes can be adjusted to meet the requirements of target species by careful selection and mixing of wastes prior to composting and by mixing...
