A two-step wood protection process using alternative wood protection agents in combination with an oil treatment
(Chapter, 2011)In this study, natural polymers were tested as possible alternatives for conventional wood preservative in a two-step process. Scots pine sapwood blocks were impregnated with chitosan, tannin, propiconazole and Wolmanit ... -
Comparison of a photogrammetric canopy height model (CHM) with a lidar derived CHM in Vestfold county
(Chapter, 2011)Digital aerial images over Vestfold county were acquired by TerraTec in summer 2007 with a Vexcel UltraCamX sensor. The flying height above-ground was approximately 2800-3000 m which resulted in images of approximately ... -
Effect of kerfing on crack formation in Scots pine log house timber
(Chapter, 2011)In Norway log buildings are normally produced from logs canted on two sides. The canted faces are prone to crack formation during drying. This can cause some disadvantages, e.g. the cracks can trap water from rainfall, ... -
Effects of wood properties on surface mould growth on coated claddings of Norway spruce
(Chapter, 2011)Development of surface moulds and staining fungi on painted spruce panels with known origin and wood properties was investigated over a period of 4 years. Materials of Norway spruce (Picea abies) were sampled from two sites ... -
ENERGY CONSUMPTION BY ENERGY WOOD SUPPLY
(Chapter, 2010) -
EXTRACTING AND CHIPPING HARDWOOD CROWNS FOR ENERGY
(Chapter, 2010) -
Extracting data for single trees from photogrammetric canopy height models and true orthophotographs
(Chapter, 2011)Top dieback and mortality of Norway spruce is a particular forest damage that has severe occurrences in scattered forest stands in southeast Norway. As a part of a project to study the extent and causes of the damage we ... -
Functional genomics of wood degradation - a project summary
(Chapter, 2011)Modified wood can provide protection against a range of wood deteriorating organisms. Several hypotheses have been put forward for the mode of action against wood decaying fungi, including inhibition of action of specific ... -
Lammas shoots in spruce - occurrence, genetics and climate
(Chapter, 2011) -
Leaching of commonly used impregnation agents affected by wood properties
(Chapter, 2011)The objective of the study was to assess the influence of wood properties on copper leaching from wood treated with preservatives. Scots pine (Pinus sylvestris L.) trees were harvested from two different stands in Norway ... -
Natural durability of wood in Norway - results after eight years above ground exposure
(Chapter, 2011)Some of the most common Norwegian wood species were tested in a Double layer test in South East Norway. After eight years of exposure the highest decay rating (≥3) was found in Scots pine sapwood, Norway spruce, alder, ... -
Pine weevils - a threat to successful regeneration
(Chapter, 2011)The pine weevil (Hylobius abietis) is an important pest to conifer seedlings in large parts of Europe. To get an objective measure of the extent of damages related to pine weevils in South-Eastern Norway, a survey was ... -
Quantifying fungi in logging residues with real-time PCR
(Chapter, 2011)Logging residues, branches and treetops after logging, were considered in the past as unsalable portions of the felled trees and remained on the landing. Currently, logging residues are harvested, stored in piles for ... -
Short and long-term effects of whole-tree thinning on forest growth
(Chapter, 2011)The use of logging residues for bioenergy is encouraged in many countries, due to an increasing demand for renewable energy. However, there is concern that removal of logging residues may cause a long-term reduction in ...
