  1. 1. A numerical and experimental study of initial defibration of wood

    Sammanfattning : A major drawback of the defibration or refining process in manufacturing pulp is that of its large energy requirements. If the mechanics of the process were better understood, large amounts of energy could probably be saved. The initial defibration seems to be crucial for both the quality of the pulp and the total consumption of energy. LÄS MER

    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; nature; urban gardening and agriculture; morality; valuations; practice; urban nature; environmentalism;

    Sammanfattning : Recent studies have shown the way assumptions about nature have blinded us to the classed and racialized morality of environmental activism and the deeply moral nature of our debates about the environment. Moral values and imaginaries that trust in the transformative capacity of nature to improve people, cities and society are ubiquitous in the urban context. LÄS MER
