  2. 21. Succession of wood-inhabiting fungal communities : diversity and species interactions during the decomposition of Norway spruce

    Author : Elisabet Ottosson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Dead wood constitutes an important substrate for biodiversity in boreal forests. As the wood decays, fungal communities develop and species associations are formed. Species interactions are thought to affect community development, but the mycelial dynamics within fungal communities are poorly understood. READ MORE

  4. 22. How has time and space affected plant biodiversity in the Hjälmö-Lådna archipelago?

    Author : Josefin Reimark; Sara Cousins; Regina Lindborg; Urban Emanuelsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical Geography; naturgeografi;

    Abstract : Traditionally European farmland management has declined during the last century, mainlydue to abandonment or intensification. When traditional management is replaced by newmethods many species are negatively affected and often threatened with extinction. READ MORE

  5. 23. Modelling and strength grading of structural timber and glulam lamellae on the basis of optical scanning and dynamic excitation

    Author : Andreas Briggert; Anders Olsson; Jan Oscarsson; Mikael Perstorper; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fibre direction; finger joint; machine strength grading; knots; tracheid effect; Norway spruce; Byggteknik; Civil engineering;

    Abstract : Machine strength grading of sawn timber is a sawmill process in which density, modulus of elasticity (MOE) and bending or tensile strength are predicted such that the timber can be assigned to strength classes. The predictions of these properties are performed using one or several so-called indicating properties (IPs), which represent a board property, or combination of board properties, measured non-destructively.

  6. 24. Train crashes : consequences for passengers

    Author : Rebecca Forsberg; Ulf Björnstig; Britt-Inger Saveman; Inggard Lereim; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Accident; crash; disaster; experiences; injuries; injury inducing objects; media coverage; railway; safety;

    Abstract : Background: Globally, and in Sweden, passenger railway transport is steadily increasing. Sweden has been relatively free from severe train crashes in the last decades, but the railway infrastructure is alarmingly worn and overburdened, which may be one reason for an increasing number of reported mishaps.
