  1. 1. Arterial Injury due to Infections in Early Life-A Possible Link in Coronary Heart Disease (Functional and Structural Studies in Animals and Children)

    Författare :Petru Liuba; Lund Pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatri; Pediatrics; Kardiovaskulära systemet; Cardiovascular system; cardiovascular risk factors; thickening; infection; endothelial dysfunction;

    Sammanfattning : Although the clinical manifestations of atherosclerotic CHD occur in adult life, the preclinical phase begins long before, seemingly already in childhood. There is supportive evidence from both epidemiological studies and animal experiments that infections could contribute to the pathogenesis of arterial disease, including atherosclerosis. LÄS MER

  3. 2. Modelling Aspects of Wastewater Treatment Processes

    Författare :Ulf Jeppsson; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatiska system; control engineering; robotics; Automation; thickening; solids flux; simulation; secondary clarifier; protozoa; predators; parameter estimation; model reduction; model identifiability; mathematical modelling; clarification; biofilm; activated sludge; robotteknik; reglerteknik;

    Sammanfattning : Wastewater treatment processes are inherently dynamic because of the large variations in the influent wastewater flow rate, concentration and composition. Moreover, these variations are to a large extent not possible to control. LÄS MER

  4. 3. Numerical study of dense particle flows under planar shear

    Författare :Junhao Dong; Beräkningskemi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dense suspension; granular flow; shear thickening; oscillatory flow; rheology; Discrete element method;

    Sammanfattning : In this thesis I conducted numerical simulations to study the flow behavior of dense particle flows composed of hard particles under planar shear using the discrete element method. The simulations were carried out in two dimensional systems, where the particles are modelled as circular discs. The discs are non-Brownian and neutrally buoyant. LÄS MER

  7. 5. Hydrophobically Modified Polymers. Rheology and Molecular Associations

    Författare :Leif Karlson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polymer self diffusion; Physical chemistry; Fysikalisk kemi; rheology; hydrophobically modified polyethylene glycol; hydrophobically modified ethyl hydroxyethyl cellulose; cyclodextrin; hydrophobically modified polymer; associative thickener;

    Sammanfattning : Structure- property relationships and thickening mechanism in aqueous solution of two hydrophobically modified polymers (HM-P) with different architecture have been investigated. The two polymers, hydrophobically modified ethyl hydroxyethyl cellulose (HM-EHEC) and hydrophobically modified polyethylene glycol (HM-PEG), are commonly used as associative thickeners in the paint industry.
