  1. 1. Utvärdering av biotopvårdande åtgärder i Grimåsbäcken. En analys av fysikaliska egenskaper och sammansättning av makroevertebrater.

    Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Författare :Björn Andermo; [2024-01-22]
    Nyckelord :Channelized streams; retention; biotope preservation; macroinvertebrates; bottom substrate; woody debris.;

    Sammanfattning : Many streams have been exposed to extensive anthropogenic impact for the benefit of forestry and agriculture. The effects has mainly been channelization characterized by lowered and straightened channels. This homogeneous morphology leads to decreased ability to retain water as well as lost connection to the floodplain. LÄS MER

  3. 2. Implementation of Level of Development for BIM Collaboration in Timber Building Subsystems Design: A Case Study of I-Joist Construction Elements

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Isabell Gustafsson; [2024]
    Nyckelord :BIM; I-Joist; LOD; Level of Development; Timber Building Subsystems;

    Sammanfattning : Due to time, cost, and environmental challenges, wood has become a more common building material even for more complex buildings. Implementing the concept of Level of Development (LOD) on timber structures could provide a tool for BIM collaboration that may save cost and time, and in the early stages mediate wood as an available building material.

  4. 3. Jämförelse mellan fyra olika bjälklag med avseende på LCA

    M1-uppsats, KTH/Byggteknik och design

    Författare :Hamza El Yasini; Malki Hanna; [2023]
    Nyckelord :;

    Sammanfattning : In today's society, there are several different options for frame solutions, such as material and design. The purpose of the work is to compare four different options of joists and show the difference between the materials considering carbon dioxide emissions. LÄS MER

  5. 4. The restoration period : a new era in forestry

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Ester Andersson; [2023]
    Nyckelord :historical forest management; past logging; restoration;

    Sammanfattning : In the last 200 years the boreal forests of Sweden have undergone a dramatic transformation. After a long history of high grading the largest trees foresters grew increasingly concerned about the state of logged over forests. The big question was how to regenerate and increase the productivity of sparse forests. LÄS MER

  7. 5. Minska miljöpåverkan och utgifterna: optimera tillgodogörande av spillmaterial

    Kandidat-uppsats, Jönköping University/JTH, Byggnadsteknik och belysningsvetenskap

    Författare :Angelina Jonsson; Wilma Panboon; [2023]
    Nyckelord :Avfallshantering; Avfallshierarkin; Behandling; Blandat avfall; Återvinning.;

    Sammanfattning : Introduction – The construction sector accounts for 40 % of all the waste in Sweden. The negative climate impact is increasing successively and to keep global warming below 2,4 – 2,6 degrees Celsius, climate measures are required. Waste reduction is a central part of preventing climate impact. LÄS MER
