  1. 1. Circular Business Model Design : Business Opportunities from Retaining Value of Products and Materials

    Författare :Julia L.K. Nußholz; Internationella miljöinstitutet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Circular Economy; business model innovation; circular business model; Resource efficiency; Reuse; Life cycle management; Value creation; sustainability assessment; Circular business model tools;

    Sammanfattning : Today our economy is largely based on linear material flows, and many products, such as electronics, furniture,building materials and textiles, are discarded even when they could still be used. Without urgent action, globalwaste is expected to increase by 70% by 2060 and global materials use is expected to more than double. LÄS MER

  3. 2. Clinical effects of reduced iron content and fortification with bovine lactoferrin in infant formula

    Författare :Maria Björmsjö; Staffan K. Berglund; Olle Hernell; Mary Fewtrell; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; infant formula; lactoferrin; bovine lactoferrin; iron; iron supplementation; iron fortification; iron status; infant nutrition; cytokines; neurodevelopment; vaccine response; infection-related morbidity; pediatrik; Pediatrics;

    Sammanfattning : Background: Breast milk, with its complex, individual and over time adapting composition, is considered the optimal source of nutrition for infants during the first months of life. Two possible contributing factors to the benefits of breastfeeding compared to infant formula-feeding are the differences in iron and lactoferrin (Lf) concentrations between breast milk and infant formula.

  4. 3. Nanoparticles for multifunctional drug delivery systems

    Författare :Jian Qin; Mamoun Muhammed; Paavo K J Kinnunen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; drug delivery; stimuli-sensitive; SPION; PLLA; PNIPAAm; gold; MRI; cytotoxicity; Pluronic; phase transfer; Materials chemistry; Materialkemi;

    Sammanfattning : Multifunctional drug delivery systems incorporated with stimuli-sensitive drug release, magnetic nanoparticles and magnetic resonance (MR) T2 contrast agents is attracting increasing attention recently. In this thesis, works on polymer nanospheres response to temperature change, superparamagnetic iron oxide nanoparticles (SPION)/polymeric composite materials for MR imaging contrast agents are summarized.

  5. 4. "Sweetenings" and "Babylonish Gabble" : Flute Vibrato and Articulation of Fast Passages in the 18:th and 19:th centuries

    Författare :Maria Bania; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Historical Performance Practice; Flute; Vibrato; Articulation; Double-tonguing; Artistic Research; Flattement; Johann Joachim Quantz; Johann George Tromlitz; Morten Raehs; Johan Helmich Roman; Charles Nicholson; Louis Drouët;

    Sammanfattning : During the 18th and 19th centuries, vibrato as well as the articulation of fast passages was often not indicated in the musical scores, but was left to the players discretion within prevailing practice. A finger-vibrato technique that this study names the flattement technique was the most recommended vibrato technique in Western classical music throughout the 18th century. LÄS MER

  7. 5. Structure-Reactivity Correlations for Reactions of Palladium(II) and Platinum(IV) Complexes

    Författare :Tiesheng Shi; Kemiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; thiol; l-methionine; maleic acid; carboxylic acid; thioether; platinum IV ; palladium II ; linear free energy relationship; volumes of activation; structure-reactivity correlation; reduction; substitution; equilibria; kinetics; mechanism; glutathione; Animal physiology; Djurfysiologi;

    Sammanfattning : The kinetics and mechanism for substitution reactions on tetraaquapalladium(II) by an extended series of thioethers, a great number of carboxylic acids, and olefins have been studied by use of UV-VIS, stopped-flow, and high-pressure stopped-flow spectrophotometry and NMR spectroscopy. Second-order rate constants k and activation parameters (activation enthalpies, entropies, and volumes) for formation of monodentate 1:1 complexes have been determined. LÄS MER
