    University essay from KTH/Betongbyggnad

    Author : Tobias Dahlin; Magnus Yngvesson; [2014]
    Keywords : Tubed Mega Frame; self-compacting concrete; construction methodology; skyscrapers; advanced formwork systems; floor cycle; construction sequencing; time planning; Tubed Mega Frame; självkompakterande betong; byggmetodik; avancerade formsystem; våningscykel; sekvensering av byggnation;

    Abstract : As a response to the ever denser cities, skyscrapers have become yet more popular and are growing more and taller than ever. A new efficient structural system for skyscrapers has been proposed by Tyréns AB, called the Tubed Mega Frame. This structural system consists of hollow concrete tubes at the perimeter of the building. READ MORE

  3. 17. Rotational Diffusion of Cellulose Nanofibrils.

    University essay from KTH/Mekanik

    Author : Johan Wärnegård; William Hedén; [2014]
    Keywords : ;

    Abstract : Cellulose nanofibrils, CNF, is a technical term for the smallest crystalline constituents of wood. Namely particles of cylindrical shape measuring 20-40 nm in diameter and 1-2 um in length. These fibrils display high ultimate tensile strength and a Young's modulus comparable to Kevlar. READ MORE

  4. 18. Epoxidised linseed oil as hydrophobic substance for wood protection : technology of treatment and properties of modified wood

    University essay from SLU/Dept. of Forest Products

    Author : Victor Fernández-Cano; [2013]
    Keywords : dimensional stability; epoxidised linseed oil; FT-IR spectroscopy; impregnation; leaching; linseed oil; mechanical properties; modified wood; Scots pine sapwood; two-step process;

    Abstract : Public concern about the release of toxic compounds from wood-based products drives legislation towards enforcing industries to find and use more sustainable solutions for wood treatment. Plant oils are good alternatives to treat wood, minimizing or even neutralizing the impact on the environment. READ MORE

  5. 19. Röjningsformens effekt på tallens (Pinus sylvestris L.) tillväxt och kvalitetsegenskaper

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Axel Eriksson; [2012]
    Keywords : kvistdiameter; elasticitetsmodul; toppröjning; stråkröjning; branch diameter; modulus of elasticity; topping; corridor cleaning;

    Abstract : Tallen (Pinus Sylvestris L.) är för den svenska skogsindustrin ett av de viktigaste trädslagen. Tallens kvalitet är påverkbar genom röjning, där röjningens intensitet och tidpunkt är avgörande för tallens diametertillväxt, årsringsbredd, kvistdiameter, krongränshöjd, stamform, juvenilvedsandel och elasticitetsmodul.

  6. 20. Design of Equipment for Characterization of Elastomers Using Impact Testing

    University essay from Lunds universitet/Maskinteknik (CI); Lunds universitet/Byggnadsmekanik

    Author : Per Sjöberg; Fredrik Axelsson; [2010]
    Keywords : Technology and Engineering;

    Abstract : Ett viktigt moment vid tillverkning av kartongmaterial till livsmedels-förpackningar är laminatorn. I laminatorn täcks råpappersmaterialet av smält polymer i det så kallade nypet. Nypet i sin tur består av en stor kylvals och en mindre gummiklädd nypvals. Genom att styra kraften som verkar på nypvalsen kan kontakttrycket i nypet regleras. READ MORE
