  1. 1. Conservation Laws, Numerical Schemes and Control Strategies for Sedimentation and Wastewater Treatment

    Författare :Sebastian Farås; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Conservation law; Temple class system; numerical scheme; continuous sedimentation;

    Sammanfattning : A consistent theme throughout this thesis is quasilinear partial differential equations (PDEs) appearing in one-dimensional models of sedimentation for solid-liquid separation of suspensions. We mainly focus on continuous sedimentation in so-called clarifier-thickeners (CTs), which are found in mineral processing and wastewater treatment. LÄS MER

  2. 2. Methylisothiazolinones. Diagnosis and prevention of allergic contact dermatitis

    Författare :Birgitta Gruvberger; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; venereology; Dermatologi; Dermatology; Prevention.; Chemical burns; Occupational dermatoses; Allergic contact dermatitis; Guinea pig maximization test; Isolation identification of contact sensitizers; Inactivation; Methylisothiazolinones; Kathon® CG; venereologi;

    Sammanfattning : Preservatives are biologically active substances which are required in water-based products/systems to prevent growth of micro-organisms. Kathon® CG (K-CG), one of several preservatives based on 5-chloro-2-methyl-4-isothiazolinon-3-one (MCI) and 2-methyl-4-isothiazolin-3-one (MI) has been shown to be a common sensitizer in dermatitis patients.

  3. 3. Hydrophobically Modified Polymers. Rheology and Molecular Associations

    Författare :Leif Karlson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 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.

  4. 4. Association and Interactions in Protein-Surfactant Systems

    Författare :Anna Stenstam; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; catanionic surfactant; SANS; NMR; gel; sodium alkylsulfate; Protein-surfactant interactions; lysozyme; LH2; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : Aggregation in protein-surfactant systems have been studied with the ambition of reaching a deeper understanding of the balance of the interaction forces involved. A pure system with maximized electrostatic interactions has been used. LÄS MER

  5. 5. Structure and Phase Stability of Polyelectrolyte-Macroion Solutions

    Författare :Marie Skepö; Kemiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi; hydrophobicity; spatially distributed interaction sites; protein-polymer interaction; Monte Carlo Simulations; redissolution; phase separation; cluster; complex; Polyelectrolytes; macroions;

    Sammanfattning : Polyelectrolytes are polymers bearing ionisable groups, which, in polar solvents, can dissociate into charged polymer chains (polyelectrolytes) and small counterions. In aqueous solutions, polyelectrolytes interact strongly with other macroions and in particular they tend to associate with objects of opposite charge and form complexes. LÄS MER
