  1. 1. Dispersion Coating for Active Food Packaging: : Aroma Interactions and Oxygen Scavenging

    University dissertation from Fakulteten för teknik- och naturvetenskap

    Author : Anna Nestorson; Karlstads universitet.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP Kemiteknik; Chemical Engineering; Kemiteknik; Active food packaging; Dispersion coating; Latex; Aroma compounds; Oxygen scavenging;

    Abstract : ABSTRACTActive packaging materials prolong the shelf life or preserve the quality of packed food by absorbing oxygen, ethylene, moisture or odours, or by releasing antimicrobial agents, antioxidants or flavours. In dispersion coating, a latex is applied onto paper or paperboard to form a barrier film against water, water vapour, oil or gases. READ MORE

  2. 2. 231Pa and Th isotopes as tracers of deep water ventilation and scavenging in the Mediterranean Sea

    University dissertation from Stockholm : Stockholm University

    Author : Sandra Gdaniec; Stockholms universitet.; Stockholms universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; geokemi; Geochemistry; 231Pa; 230Th; 232Th; Mediterranean Sea; scavenging; deep water ventilation; Protactinium; Thorium; particle transport; deep water circulation;

    Abstract : The naturally occurring isotopes 231Pa and 230Th are used as tracers of marine biogeochemical processes. They are both produced from the radioactive decay of their uniformly distributed uranium parents (235U and 234U) in seawater. READ MORE

  4. 4. Hygroscopic Growth of Atmospheric Aerosol Particles and Its Relation to Nucleation Scavenging in Clouds

    University dissertation from Division of Nuclear Physics, Lund University, Box 118, S-221 00 Lund, Sweden

    Author : Birgitta Svenningsson; Lund University.; Lunds universitet.; [1997]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aerosol formation; atmospheric aerosols; hygroscopic growth; nucleation scavenging; cloud; water activity; external mixing; tandem differential mobility analyser; Kärnfysik; cloud condensation nuclei spectra; Nuclear physics; TDMA; Fysicumarkivet A:1997:Svenningsson; inorganic salts;

    Abstract : Aerosol particles in the atmosphere are important in several aspects. Some major aerosol constituents that are deposited in ecosystems are acidic or fertilisers and some minor or trace constituents are toxic. READ MORE

  5. 5. Cell-Penetrating Peptides for Mitochondrial Targeting

    University dissertation from Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Author : Carmine Pasquale Cerrato; Stockholms universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mitochondrial targeting; cell-penetrating peptides; antioxidant activity; scavenging ability; oligonucleotide delivery; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : Mitochondria have simply been known as the cell’s powerhouse for a long time, with its vital function of producing ATP. However, substantially more attention was directed towards these organelles once they were recognized to perform several essential functions having an impact in cell biology, pharmaceutics and medicine.
