  1. 1. Colour Response in Drying of Nordic Hardwoods

    Författare :Stefan Stenudd; Thomas Thörnqvist; Timo Kärki; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; beech; Betula pendula; birch; CIELAB; discolouration; drying; Fagus sylvatica; log storage; oak; press drying; wood colour; Quercus robur; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : Colour and appearance of hardwood are of great importance for the interiorand furniture industry. The widespread use of transparent surface treatmentand a fashion that prescribe light colour on many species, means that deviationfrom the ideal have considerable impact on the industrial operations.

  3. 2. Water Curtains in Gas Storage. An Experimental Study

    Författare :Carl-Olof Söder; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; analytical simulations; unlined gas storage; jointed rock; gas migration; gas containment; geo-hydrological test methods; hydromechanical breakdown;

    Sammanfattning : Water curtains have been used for more than 20 years to prevent the escape of gas from caverns excavated in rock. Today, the use of water curtains appears to be increasing, with applications in various forms of storage caverns. LÄS MER

  4. 3. Characterization, toxicity and treatment of wood leachate generated outdoors by the wood-based industry

    Författare :Henric Svensson; Linnéuniversitetet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Wood leachate; Log yard runoff; Stormwater; Toxicity; Artemia salina; Vibrio fischeri; Constructed wetlands; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : Wood is a natural raw material, and would hardly be considered a risk to the environment. However, the handling of wood materials on an industrial scale has been shown to have a negative impact on water bodies that run-off from industrial sites that process wood-based materials. LÄS MER

  5. 4. Management of forest biomass terminals

    Författare :Kalvis Kons; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Terminals and log-yards are becoming increasingly important in Nordic forest supply chains because of the need to support the rising production capacity of pulp mills and heat and power plants. Most modern terminals and log-yards handle multiple assortments, must accommodate multiple incoming and outgoing modes of transport, and have multiple storage areas. LÄS MER

  7. 5. Prediction of wood species and pulp brightness from roundwood measurements

    Författare :David Nilsson; Ulf Edlund; Michael Sjöström; Olav Kvalheim; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Design of Experiments; ISO brightness; Multivariate Image Analysis; Multivariate Modelling; NIR spectroscopy; Norway spruce; PCA; PLS; Roundwood; Scots pine; Organic chemistry; Organisk kemi;

    Sammanfattning : This thesis presents a number of studies, where a multivariate approach was taken to construct models that predict wood species and thermo mechanical pulp brightness from roundwood of Norway spruce and Scots pine. The first and second studies produced multivariate prediction models for wood species from the bark of spruce and pine. LÄS MER
