  2. 1. Towards the Rational Design of Molecularly Imprinted Polymers

    Author : Håkan S Andersson; Ann-Christin Koch-Schmidt; Ian A Nicholls; Klaus Mosbach; Richard F Venn; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thermodynamics; Molecular Recognition; Polyvalency; Cooperativity; Electrostatic Interactions; Hydrophobic Effect; Chromatography; Frontal Analysis; HPLC; Spectroscopy; Molecularly Imprinted Polymer; Molecular Imprinting; Crown Ether; Template Polymerisation; Cyclodextrin; Biochemistry; Metabolism; Biokemi; Biotechnology; Bioteknik; molecular recognition; Biokemi;

    Abstract : Molecular imprinting is a technique by which polymeric materials selective for a given target molecule can be created through a casting procedure. Functionalised monomers are added to a solution of molecular templates. READ MORE

  4. 2. Neurotoxic Effects of Nicotine During Neonatal Brain Development : Critical Period and Adult Susceptibility

    Author : Emma Ankarberg; Per Eriksson; Richard F. Seegal; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; nicotine; neonatal development; behaviour; nicotinic receptors; susceptibility; cholinergic system; paraoxon; PBDE; Biologi; Biology; Biologi;

    Abstract : This thesis examined neurotoxic effects of nicotine exposure during a defined critical period of neonatal brain development in mice.In our environment there are numerous hazardous contaminants that an individual can be exposed to during its entire lifetime. READ MORE

  5. 3. Grease lubrication mechanisms in bearing seals

    Author : Pieter Baart; Richard F. Salant; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : Rolling bearings contain seals to keep lubricant inside and contaminants outside the bearing system. These systems are often lubricated with grease; the grease acts as a lubricant for the bearing and seal and improves the sealing efficiency. In this thesis, the influence of lubricating grease on bearing seal performance is studied. READ MORE

  6. 4. Of seagrass and society : Exploring contributions of tropical seagrass meadows to food security

    Author : Benjamin Jones; Johan S. Eklöf; Lina M. Nordlund; Leanne C. Cullen-Unsworth; Richard K.F. Unsworth; Maricela de la Torre-Castro; Christina Hicks; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Biodiversity; Blue food; Food security; Social-ecological systems; Small-scale fisheries; Seagrass meadows; marinbiologi; Marine Biology;

    Abstract : Conserving biodiversity while simultaneously feeding a growing population is one of the grand challenges of the Anthropocene. Recently, global assessments have shone a light on the importance of the marine environment for the supply of food (often termed blue food), as well as the diverse and many livelihood opportunities associated to it.

  7. 5. Infrared spectroscopy as a tool to reconstruct past lake-ecosystem changes : Method development and application in lake-sediment studies

    Author : Carsten Meyer-Jacob; Richard Bindler; Hendrik Vogel; Jan Karlsson; John F. Boyle; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fourier transform infrared spectroscopy; visible-near infrared spectroscopy; PLS regression; biogenic silica; climate change; carbon cycling; lake-water quality; geochemistry; paleolimnology; Holocene; Lake El’gygytgyn; Torneträsk;

    Abstract : Natural archives such as lake sediments allow us to assess contemporary ecosystem responses to climate and environmental changes in a long-term context beyond the few decades to at most few centuries covered by monitoring or historical data. To achieve a comprehensive view of the changes preserved in sediment records, multi-proxy studies – ideally in high resolution – are necessary. READ MORE
