  2. 21. Elastohydrodynamic lubrication under non-steady conditions

    Author : Roland Larsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : The six papers presented in this thesis consider the effects on elastohydrodynamic lubrication (ehl) of non-steady conditions. The vast majority of ehl investigations, both experiemental and theoretical, utilise steady state conditions, i.e. constant load, velocity, geometry and temperature. READ MORE

  4. 22. Faba bean foods: Structure and texture : Evaluation of faba bean component behaviours in different product matrices

    Author : Klara Nilsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Faba bean (Vicia faba minor) is a cool-climate crop that could serve as a locally sourced sustainable ingredient in transition towards a more plant-based diet in temperate regions. Poor texture is one of the main aversion factors of plant-based foods, so this thesis characterised the functionality of faba bean components and their effect on structure and texture in different food matrices.

  5. 23. Extension of PC-SAFT to model inhomogeneous and transport properties

    Author : Gulou Shen; Georgios Kontogeorgis; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : CO2 separation plays an important role in greenhouse gas emission mitigation, in bio-fuel production via biomass gasification as well as in biogas upgrading. The current CO2 separation technologies are energy intensive, and new cost-effective CO2 separation technologies are needed. READ MORE

  6. 24. Characterization of cellulose pulps and the influence of their properties on the process and production of viscose and cellulose ethers

    Author : Peter Strunk; Bertil Eliasson; Roland Adden; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cellulose ether; dissolving pulp; ethyl hydroxyethyl cellulose; hardwood; multivariate data analysis; reactivity; softwood; sulfate; sulfite; viscose;

    Abstract : Today’s market offers an ever-increasing range of cellulose pulps (derivative pulps) made fromvarious wood types through different delignification processes. Each pulp segment has its uniquecharacteristics, which makes it difficult for the producer of cellulose derivatives to choose the mostsuitable pulp for optimum processability and product quality.

  7. 25. Dynamical properties of interfacial water and its role for biomolecular dynamics

    Author : Helen Jansson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Water is the foundation of life, and without it life as we know it would not exist. An organism consists to a large extent of water, and apart from a few larger reservoirs, a large fraction of the water in a body is closely associated with surfaces of biomolecules of different kinds. This water is denoted biological water. READ MORE
