  2. 11. The influence of fibre characteristics on bulk and strength properties of TMP and CTMP from spruce

    Author : Niklas Klinga; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; Kemiteknik;

    Abstract : This thesis is intended to contribute to an increased knowledge about the influence of fibre characteristics on bulk and strength properties of thermomechanical pulp (TMP) and chemithermomechanical pulp (CTMP) from spruce. It deals with laboratory sheet properties and how they are affected by the conditions during pressing and drying, e.g. READ MORE

  4. 12. The Influence of Molecular Adhesion on Paper Strength

    Author : Malin Eriksson; Lars Wågberg; Orlando Rojas; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi;

    Abstract : This thesis deals with the influence of molecular adhesion on paper strength. By combining the use of high-resolution techniques and silica/cellulose surfaces, with various fibre–fibre and sheet testing techniques, new information regarding the molecular mechanisms responsible for paper strength has been obtained.

  5. 13. Properties of Ugandan minerals and fireclay refractories

    Author : John Baptist Kirabira; Stefan Jonsson; Thomas Johansson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; kaolin; clay; Ugandan minerals; fireclay; refractory; powders characterization; beneficiation; ceramics; mullite; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Abstract : Development of products which can be produced from a country’s natural resources is very important as far as the industrialization of a nation and saving foreign exchange is concerned. Presently, industries in Uganda and the other states in the Lake Victoria region import all refractory-related-consumables, as the demand cannot be met locally. READ MORE

  6. 14. Delubrication of Chromium Prealloyed Powder Metallurgy Steels

    Author : Seshendra Karamchedu; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alloyed sintered steels; delubrication; surface oxide; sintering atmosphere; processing atmosphere control; lubricant;

    Abstract : Consolidation of steel components produced by means of powder metallurgy (PM) is achieved typically through compaction and sintering. During consolidation, final dimensions of the part are already achieved after compaction, while sintering imparts strength to the components. READ MORE

  7. 15. Green-Blue Water Potential: : Building water resilience to attain the SDGs on food and poverty in Africa

    Author : Maganizo Kruger Nyasulu; Ingo Fetzer; Stefan Liersch; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; agriculture; green-blue water resilience; sustainable development goals; climate change; land use change; vetenskap om hållbar utveckling; Sustainability Science;

    Abstract : Attaining the Sustainable Development Goals (SDGs) of eradicating hunger and securing sustainable food for all by 2030, constitutes a major global challenge, particularly in sub-Saharan Africa (SSA). Here, malnourishment, poverty, and population growth are among the highest in the world, and some regions are constantly subject to extreme water variability and scarcity. READ MORE
