  1. 1. Aspects on wettability and surface composition of modified wood

    Författare :Lars-Elof Bryne; Ove Söderström; Charles R. Frihart; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wettability; contact angle; work of adhesion; Lewis acid-base; modified wood; Building engineering; Byggnadsteknik;

    Sammanfattning : Wood is often combined with other materials such as thermoplastics, adhesives and coatings. In general, combinations of wood and polymers especially in outdoor exposure have poor long-term durability. LÄS MER

  3. 2. Adhesion to machined and laser ablated wood surfaces

    Författare :Micael Stehr; KTH; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; ablation; adhesion; checks; coating; cracks; excimer laser; gluing; IR laser; mechanical machining; mechanical weak boundary layer; microscopy; notched specimens; pine; planing; sample preparation; sawing; scanning electronmicroscopy; spruce; tip-cracks; UV laser; weak boundary layer; wood;

    Sammanfattning : This thesis is a contribution to the R&D-program ValueActivation at KTH,Division of Wood Technology and Processingand containsfive papers related to the evaluation and development ofmachining techniques (mechanical and irradiation treatments)whereby weak boundaries at the wood surfaces in the form of(mechanical) weak boundary layers and (micro) cracks due tomechanical treatment can be avoided.The first paper describes the development of a method–using a UV laser–to study the mechanically weakenedboundaries.

    Författare :Olof Hedling; Filmvetenskap; []
    Nyckelord :HUMANIORA; HUMANITIES; Cambridge English School; F. R. Leavis; Hollywood cinema; modernism; gender criticism; anti-modernism; Humaniora; Humanities; film studies; Film criticism;

    Sammanfattning : British film critic Robin Wood began to publish on film in 1960. Since then, he has written or co-written 13 books, and also published hundreds of essays and articles in books, in journals, and in different encyclopedias. At the same time, Wood has been a key figure in the development of what has become academic film studies. LÄS MER

  5. 4. Fungal taxonomy and systematics in the digital era, with an outlook on the cantharelloid clade (Basidiomycota)

    Författare :R. Henrik Nilsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cantharelloid clade; ectomycorrhiza; Agaricomycetes; phyloinformatics; barcoding;

    Sammanfattning : Fungi form a large and ubiquitous group of organisms where species identification and delimitation on morphological grounds often fall short. DNA sequences have proved an invaluable information source for these pursuits and are now routinely used in most mycological laboratories. LÄS MER

  7. 5. On reflections of wood : wood quality features modelled by means of multivariate image projections to latent structures in multispectral images

    Författare :Olle Hagman; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Sammanfattning : Classifying logs and boards has an essential economic impact on the forest products industry. In a modern production chain, quality control and raw material specifications are essential to fulfill production system demands as well as end user demands. LÄS MER
